BRADY CITY MANAGER DATE: FEBRUARY 9, 2010 SUBJECT: MODIFICATION TO GRADING PERMIT FOR THE PROJECT KNOWN AS LA STRADA, LOCATED WITHIN THE NORTHERN PORTION OF THE CANYON CREEK SPECIFIC PLAN, TO PERMIT SUPPLEMENTAL GRADING OF THE FOLLOWING: 22 REMAINDER LOTS, A PARK SITE, FOUR (4) RESIDENTIAL STREETS, DRAINAGE DITCHES, AND PROCESSING OF CLASS 11 BASE Background In April 2005, the City Council approved General Plan Amendment No. 2005-01 and Tentative Tract Map No. 32077, conducted first and second reading of an ordinance approving Canyon Creek Specific Plan No. 85-1, and adopted Mitigated Negative Declaration No. 2005-01 (State Clearinghouse No. 2005041168: the "MND") for a project commonly known as La Strada. According to the MND, the La Strada project was expected to require approximately 810,000 cubic yards each of cut and fill, resulting in a balance of cut and fill on the project site. It was not anticipated that material would be transported to or from the project site, as all grading material would be absorbed and utilized in various areas on- site. On February 8, 2008, after plan check was submitted and approved, the City of Lake Elsinore issued the project owner Grading Permit No. 07-3003 for the grading of 170,000 cubic yards of material for a borrow site and erosion control. Grading Permit No. 07-3003 was set to expire August 6, 2008. Immediately after Grading Permit No. 07-3003 was issued, the project owner commenced grading in accordance with the permit and completed this grading prior to the permit expiration date. Thereafter, in June 2008, the City issued the project owner Grading Permit No. 08-294, which permitted rough grading of 1,715,940 cubic yards of combined cut and fill on-site. The project owner posted security and commenced grading pursuant to the permit. CC February 09, 2010 Item No. 10 Page 1 of 85 Modification to La Strada Grading Permit February 9, 2010 Page 2 of 5 By letter dated November 19, 2008, the project owner's civil engineer certified that Lots 1 through 15, 19 through 32, 38 through 59, 73 through 75, 78 through 82, 86, 107 through 112, and 118 through 128 had been rough graded in accordance with the approved grading plan. As a result, the project owner requested that the security that it had posted in connection with the issuance of the Grading Permit 08-294 be reduced by fifty percent (50%). Staff responded to the security reduction request by letter dated December 9, 2008. Staff informed the project owner that the City would reduce the owner's grading bond by 50% but would not release the cash bond until precise grading had been completed and permanent erosion control measures were in place. Based on this statement, it was clear that additional grading work needed to be completed on-site. The portions of the project site that were not certified by the project owner's civil engineer are marked by a significant amount of rock material. In order to complete the project grading, the rock must be removed and transported off-site. Neither the MND prepared for the La Strada project nor the grading permits issued contemplated removal of rock material from the project site or the sizing of the rock material to prepare it for off-site transport. Discussion Modification Request The applicant is requesting a modification to the existing Grading Permit 08-294 to include the processing and removal of in situ rock material. Specifically, the applicant requests the following: permission to grade twenty-two (22) remaining residential lots, a park site, four (4) residential streets, on-site slope embankments including approximately 1,000 feet of drainage ditches and processing of approximately 12,000 tons of Class II base for on-site use. In addition, the applicant requests permission to grade, process and export approximately 104,000 tons of material. This activity will include moving material to a rock crusher where it will be reduced to gravel then separated into various sizes for off- site sale. Once sized, the material will be exported by way of trucks carrying loads of up to 25 tons (or 16 cubic yards of material) per load to various locations. There are three potential hauling routes for the export of the 104,000 tons of material. They are: • Haul Route 1 - Project site to La Strada to Summerhill to Diamond Drive to 1-15 (Attachment 1). CC February 09, 2010 Item No. 10 Page 2 of 85 Modification to La Strada Grading Permit February 9, 2010 Page 3 of 5 • Haul Route 2 - Project site to Bella Vista to Dirt Road to Greenwald to SR-74 (Attachment 2). • Haul Route 3 - Project site to extension of La Strada (new alignment) to Camino Del Norte to Main Street to 1-15 (Attachment 3). New Grading Ordinance and Notice of Public Hearing In the past, issuance and modification of grading permits, which includes hauling activity, was an administrative function. However, on January 12, 2010, the City Council conducted second reading of an ordinance amending Chapter 15.72 of the Lake Elsinore Municipal Code regarding grading standards by adding Section 15.72.065 and amending Sections 15.72.020, 15.72.030, 15.72.050 Subpart F and 15.72.070 Subparts A and B. The new grading ordinance requires that any hauling over 5,000 cubic yards of earthen material be evaluated and approved by the City Council after a noticed public meeting. This, ordinance will become effective thirty days from second reading, or February 11, 2010. Given that the proposed modifications to Grading Permit 08-294 are under consideration tonight, February 9, 2010, before the provisions of the new grading ordinance become effective, the applicant's request is not formally subject to the new grading ordinance. However, the applicant agreed to comply with the public meeting and noticing requirements of the new grading ordinance. Staff accordingly mailed notice to all property owners within a minimum of three hundred (300) feet of the access road(s) to the grading site as well as property owners within three hundred (300) feet of the La Strada project site at least 10 days in advance of the day, time and place of this City Council public meeting. Notice was also posted on the project site. CEQA Analysis In accordance with the California Environmental Quality Act (Cal. Pub. Res. Code 21000 et seq.: "CEQA") and the State Guidelines for Implementation of CEQA (14 C.C.R. 15000 et seq.: "CEQA Guidelines"), the attached Initial Study/Addendum was prepared in order to determine whether the proposed modifications to the grading permit would result in a change in circumstances, new impacts, or new information of substantial importance requiring the preparation of a new or subsequent or supplemental MND. A copy of the Initial Study/Addendum to the MND is attached hereto as Attachment 4 for the Council's review. The Initial Study/Addendum reviews new information of substantial importance that was not known and could not have been known with exercise of reasonable diligence at the time the MND was certified (i.e., the existence of rock material that must be removed from the project site). It further examines whether, as a result of any changes or any new information, preparation of a subsequent or supplemental MND is required. This CC February 09, 2010 Item No. 10 Page 3 of 85 Modification to La Strada Grading Permit February 9, 2010 Page 4 of 5 examination includes an analysis of the provisions of Section 21166 of CEQA and Section 15164 of the State CEQA Guidelines and their applicability to the proposed activity. The focus of the examination is on whether the Final MND adequately addresses the impacts associated with development of the proposed activity. Based upon the information provided in the attached Initial Study/Addendum, the modifications to the grading permit with Haul Routes 1 or 2 would not result in any new significant impacts and the conclusions in the MND prepared for the La Strada project support the applicant's request. If Haul Route 3 is selected, however, additional CEQA analysis would be required, and an addendum would not provide adequate analysis. Fiscal Impact None. Recommendation 1. By minute action, approve the applicant's requested modifications to Grading Permit No. 08-294 set forth in this Staff Report. 2. By minute action, select which of the three proposed Haul Routes set forth in this Staff Report the applicant shall follow. 3. Alternatives for Addendum: a. If Haul Route 1 or 2 is selected, by minute action, approve the Addendum to MND. b. If Haul Route 3 is selected, by minute action, reject Addendum and direct staff to prepare further environmental review of Haul Route 3.

That Final MND included an amendment to the overall Canyon Creek Specific Plan (Amendment No.3). The Canyon Creek Specific Plan was also analyzed in an EIR (SCH No. 2005041168). These documents serve as the environmental review of the proposed activity, as required pursuant to the provisions of the California Environmental Quality Act (CEQA), Public Resources Code Section 21000, et seq., and the State CEQA Guidelines. A complete description of the proposed activity is included in Section 2.0. Pursuant to the provisions of CEQA and the State CEQA Guidelines, the City of Lake Elsinore is the Lead Agency and is charged with the responsibility of deciding whether or not to approve the proposed activity. As part of the decision-making process, the City is required to review and consider the potential environmental effects that could result from the modification of the project analyzed in the previously certified EIR. 1.2 PREVIOUS ENVIRONMENTAL DOCUMENTATION In 2005, the Lake Elsinore City Council adopted the Final MND for the La Strada project. The Final MND addressed potential impacts associated with the General Plan Amendment, Specific Plan Amendment and Tentative Tract Map for the La Strada project. All environmental subject areas were determined to either have no impact, be less than significant in relation to the identified significance threshold levels, or to be mitigated to a level of less than significant through recommended mitigation measures. 1.3 FINDINGS OF THIS INITIAL STUDY/ADDENDUM Pursuant to CEQA and the State CEQA Guidelines, this Initial Study/Addendum has been prepared in order to determine whether the proposed modified grading permit for the La Strada project will result in a change in circumstances, new impacts, or new information of substantial importance requiring the preparation of a new or subsequent or supplemental MND. This Addendum reviews new information that was not known and could not have been known with exercise of reasonable diligence at the time the Final MND was certified. It further examines whether, as a result of any changes or any new information, preparation of a subsequent or supplemental MND is required. This examination includes an analysis of the provisions of Section 21166 of CEQA and Section 15164 of the State CEQA Guidelines and their applicability to the proposed activity. The focus of the examination is on whether the Final MND adequately addresses the impacts associated with the proposed activity. Pursuant to CEQA and the State CEQA Guidelines, the City's environmental review of the proposed activity is limited to examining the environmental effects associated with the changes between the previously adopted Final MND and the potential impacts which may result from implementation of the proposed activity. This focus is due to the fact that the Final MND has already addressed the environmental impacts associated with the La Strada project and that the Lake Elsinore City Council determined that the Final MND was adequate and met the provisions of CEQA. La Strada Modified Grading Permit 1 City of Lake Elsinore Canyon Creek Specific Plan February 2010 CC February 09, 2010 Item No. 10 Page 9 of 85 Initial Studv Addendum Based upon the information provided in the attached Initial Study/Addendum, the modified grading permit with Haul Routes 1 or 2 would not result in any new significant impacts and the conclusions in the Final MNM prepared for the La Strada project are valid the proposed activity. If Haul Route 3 is selected, additional CEQA analysis would be required, and more information would be needed to determine if an addendum would provide an adequate analysis. 1.3.1 Use of an Addendum to a Previously Certified CEQA document Section 15164(b) of the State CEQA Guidelines states that an Addendum to a negative declaration shall be prepared "if only minor technical changes or additions are necessary or none of the conditions described in Section 15162 calling for preparation of a subsequent EIR or negative declaration have occurred." Section 15162 of the State CEQA Guidelines identifies the conditions that require preparation of a subsequent negative declaration. A proposed change in a project will require preparation of a subsequent negative declaration if. 1. The change in the project is substantial. Substantial changes in the project are those that would require major revision of the previous negative declaration due to the involvement of new significant environmental effects, or if a substantial increase in the severity of previously identified significant effects has occurred. 2. The circumstances under which the project is undertaken have substantially changed. Substantial changes in circumstances are those defined as those that would require major revisions of the previous negative declaration in order to describe and analyze new significant environmental effects, or any changes that would cause a substantial increase in the severity of the previously identified significant effects. 3. New information of substantial importance, which was not known and could have not been known, with the exercise of reasonable diligence at the time the previous negative declaration was certified, shows: A. The project will have one or more significant effects not discussed in the previous negative declaration; B. The significant effects previously examined will be substantially more severe than identified in the previous negative declaration; C. Mitigation measures or alternatives previously found not to be feasible would in fact be feasible, and would substantially reduce one or more significant effects of the project, but the project proponent declines to adopt the mitigation measures or alternatives; or D. Mitigation measures or alternatives that are considerably different from those analyzed in the previous negative declaration would substantially reduce one or more significant effects on the environment, but the project proponent declines to adopt the mitigation measures or alternatives. If none of the above conditions is met, the City is not permitted to require preparation of a subsequent negative declaration. Rather, the City may require preparation of an Addendum, or the City may decide that no further environmental documentation is necessary. La Strada Modified Grading Permit 2 City of Lake Elsinore Canyon Creek Specific Plan February 2010 CC February 09, 2010 Item No. 10 Page 10 of 85 Initial Studv Addendum This Initial Study/Addendum has evaluated each of the issues addressed in the Final MND, as well as each of the issues contained in the checklist presented in Section 3.0 of this document. Based on this analysis and the information contained herein, there is no evidence that the proposed activity requires major changes to the Final MND if the modified grading plan uses Haul Routes 1 or 2. Comparison of the approved La Strada project with the proposed activity, as described in Section 2.3 of this document, indicates that there are no new significant environmental impacts associated with implementation of the proposed activity. If Haul Route 3 was selected, additional CEQA analysis beyond an addendum would be required. This Initial Study/Addendum relies on use of an Environmental Checklist Form (Form), as suggested in Section 15063 (d)(3) of the State CEQA Guidelines. The Form is used: • To evaluate whether or not there are any new or more severe significant environmental effects associated with implementation of the proposed activity and proposed amendments; and • To review whether there is new information or circumstances that would require preparation of additional environmental documentation in the form of a subsequent or supplemental MND, or if an Addendum is appropriate. Section 3.0 of this document contains the Checklist Form and explains the basis for each response to the questions on the Form. 1.4 EXISTING DOCUMENTS TO BE INCORPORATED BY REFERENCE Section 15150 of the State CEQA Guidelines permits an environmental document to incorporate by reference other documents that provide relevant data. The documents outlined in this section are hereby incorporated by reference, and the pertinent material is summarized throughout this Initial Study/Addendum, where that information is relevant to the analysis of impacts of the proposed activity. Any document incorporated by reference is available for review at City of Lake Elsinore Planning Division. City of Lake Elsinore. 2005.

The site is located east of Lake Elsinore and Interstate 15, and approximately one mile west of Canyon Lake. Figure 1 shows the project site in a regional and local context. 2.2 DISCRETIONARY ACTIONS The proposed activity requires the following discretionary actions by the City of Lake Elsinore: • Approval of modifications to grading permit. 2.3 PROJECT DESCRIPTION The proposed project supplemental grading operation would grade 22 remaining residential lots, a park site, four (4) residential streets, on site slope embankments including approximately 1000-feet of drainage ditches and processing of approximately 12,000 tons of Class II base for on-site use within the approved La Strada project area. The proposed activity would also grade, process and export approximately 104,000 tons of material. This activity will include moving material to an onsite rock crusher where it will be reduced to gravel then separated into various sizes for offsite sale. Once sized, the material will be exported via trucks to various locations. These trucks are capable of hauling 25-tons or 16 cubic yards per load. Three potential hauling routes for the export of the 104,000 tons of material are considered in this analysis: Haul Route 1: From project site to I-15 via La Strada, Smnmerhill Drive and Diamond Drive (Figure 2). Haul Route 2: From the project site to SR-74 via La Strada, Bella Vista, and an unimproved road, and Greenwald Avenue (Figure 3). Haul Route 3: From project site to I-15 via New La Strada, Camino del Norte and Main Street ramps (Figure 4). 2.4 EXISTING CONDITIONS The Final MND for the La Strada project included a summary of existing on-site conditions. Conditions within the limits of the project area have undergone grading since the adopted of the Final MND. 2.5 FINDINGS AND CONCLUSIONS Based on the proposed activity description, each of the issues addressed in the Final MND as well as each of the issues contained in the checklist presented in Section 3.0 of this document have been evaluated, leading to the following findings and conclusions: La Strada Modified Grading Permit Canyon Creek Specific Plan 4 City of Lake Elsinore February 2010 CC February 09, 2010 Item No. 10 Page 12 of 85 Initial Studv Addendum • The modified grading permit will be required to implement previously approved mitigation measures, as applicable, from Final MND 2005-1. • Selection of Haul Routes 1 or 2 will not result in any substantial changes which would require the preparation of a subsequent or supplemental MND. This Addendum provides adequate CEQA evaluation. • Selection of Haul Route 3 would require additional CEQA analysis beyond an addendum, including analysis related to biological resources and cultural resources. Thus, with selection of Haul Route 1 and 2, none of the conditions described in Section 15162 calling for preparation of a subsequent MND have occurred. The change in the project analyzed in the Final MND for the La Strada project is not substantial. Substantial changes in the project are those that would require "major revisions of the previous MND due to the involvement of new significant environmental effects, or a substantial increase in the severity of previously identified significant effects." As noted above, the proposed modifications to the grading permit will not result in new significant impacts or a substantial increase in the severity of previously identified significant effects. The circumstances under which the project is undertaken have substantially changed. Substantial changes in the circumstances under which the project is being undertaken are those defined as those that would "require major revisions of the previous MND due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects." The only changes required in the La Strada Final MND to address the impacts of the proposed modifications to the grading permit are to include the proposed activity description contained in this Addendum as part of the La Strada MND project description. 3. New information of substantial importance, which was not known and could have not been known, with the exercise of reasonable diligence at the time the previous MND was certified, shows: • "The project will have one or more significant effects not discussed in the previous MND...; • Significant effects previously examined will be substantially more severe than shown in the previous MND; • Mitigation measures or alternatives previously found not to be feasible would in fact be feasible, and would substantially reduce one or more significant effects of the project, but the project proponents decline to adopt the mitigation measure or alternative; or • Mitigation measures or alternatives that are considerably different from those analyzed in the previous EIR would substantially reduce one or more significant effects on the environment, but the project proponents decline to adopt the mitigation measure or alternative." As noted above, there is no evidence that any of these conditions exist. Section 15164 of the State CEQA Guidelines states that an Addendum to a negative declaration shall be prepared "if some changes or additions are necessary, but none of the conditions described in Section 15162 calling for preparation of a subsequent MND have occurred." Since none of the conditions of Section 15162 of the State CEQA Guidelines occur, an Addendum to Final MND 2005-1 is the appropriate form of environmental documentation under CEQA for the proposed activity.

Activity Description: The La Strada supplemental grading operation proposes to grade 22 remaining residential lots, a park site, four residential streets, on-site slope embankments including approximately 1,000 feet of drainage ditches, and processing of approximately 12,000 tons of Class II base for on-site use. The activity is also proposing to grade, process and export approximately 104,000 tons of material. This activity will include moving material to an onsite rock crusher where it will be reduced to gravel then separated into various sizes for offsite sale. Once sized, the material will be exported via trucks to various locations. These trucks are capable of hauling 25-tons or 16 cubic yards per load. Three potential hauling routes for the export of the 104,000 tons of material are considered in this analysis: Haul Route 1: From project site to I-15 via La Strada, Summerhill Drive and Diamond Drive (Figure 2). Haul Route 2: From the project site to SR-74 via La Strada, Bella Vista, and an unimproved road, and Greenwald Avenue (Figure 3). Haul Route 3: From project site to I-15 via New La Strada, Camino del Norte and Main Street ramps (Figure 4). 9.

Public Agencies Whose Approval is City of Lake Elsinore Required (e.g., permits, financing approval, or participation agreement): La Strada Modified Grading Permit 2 City of Lake Elsinore Canyon Creek Specific Plan February 2010 CC February 09, 2010 Item No. 10 Page 19 of 85 Initial Determination: (To Be Completed by the Lead Agency) On the basis of this initial evaluation: The City finds that the proposed activity COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared. The City finds that although the proposed activity could have a significant effect on the environment, there will not be a significant effect in this case because the mitigation measures described on an attached sheet have been added to the project. A NEGATIVE DECLARATION will be prepared. The City finds the proposed activity may have a significant effect(s) on the environment, but at least one effect: (1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and (2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets. If the effect is a potentially significant impact or potentially significant unless mitigated an ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to addressed. ❑ The City finds that changes to the project or the circumstances under which the project would be undertaken require major revisions to the previous EIR in order to make the previous EIR adequately apply to the proposed activity in accordance with Public Resources Code Section 21166 and CEQA Guidelines Section 15163. Thus, a SUBSEQUENT EIR shall be prepared. The City finds that changes to the project or the circumstances under which the activity would be undertaken with Haul Route 3 would require only minor revision to the previous MND in order to make the previous MND adequately apply to the proposed activity in accordance with Public Resources Code Section 21166 and CEQA Guidelines Section 15163. Thus, a SUPPLEMENTAL MND shall be prepared. Alternatively, The City finds that the significant effects that would result from the proposed activity with Haul Routes 1 and 2 have been addressed in an earlier MITIGATED NEGATIVE DECLARATION, and that none of the determinations set forth in Public Resources Code Section 21166 and State CEQA Guidelines Section 15162 can be established.

EARLIER ANALYSES Earlier analyses may be used where, pursuant to the tiering, program EIR, or other CEQA process, one or more effects have been adequately analyzed in an earlier FIR or Negative Declaration (Section 15063[c][3][D]). • Mitigated Negative Declaration No. 2005-1 for the La Strada Planning Area (General Plan No. 2005-01/Canyon Creek Speck Plan No. 85-1 Amendment No. 3ITentative Tract Map No. 32007). SCH No. 20050411 68 (April 2005). La Strada Modified Grading Permit Canyon Creek Specific Plan 17 City of Lake Elsinore February 2010 CC February 09, 2010 Item No. 10 Page 34 of 85 Initial Discussion of the Environmental Checklist Form Responses The following Initial Study Environmental Checklist Form responses provide a summary and substantiation of the findings of the City of Lake Elsinore. The proposed activity is the approval of a modified grading plan. 1. Aesthetics - Would the proposed activity: a) Have a substantial adverse effect on a scenic vista? MND No. 2005-1 Conclusion: Less than Significant The Final MND prepared for the La Strada Planning Area concluded the project site was not located within or near a scenic vista (per Exhibit 28 of the General Plan). Therefore, it was concluded that the project would have a less than significant impact on scenic vistas (page 27). Discussion of Modified Grading Permit: Grading activities would occur within the same project footprint and result in the same final grading elevations and designs. Under Haul Routes 1 and 2 no additional grading or landform modification would be required, as hauling would occur on existing roads. Under Haul Route 3, a new road (New La Strada) would be constructed to connect the project site to I-15. However, since no scenic vistas occur in the project vicinity, no additional impact associated with the new road is anticipated. Finding. Implementation of the modified grading plan would neither negate nor exacerbate the significance of the impact to scenic vistas/resources. The impact would remain less than significant regardless of implementation of the proposed activity. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a State scenic highway? MAD No. 2005-1 Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that with incorporation of a mitigation measure (Lb-1), the project would have a less than significant impact to scenic resources (page 27). This mitigation measure calls for the developer to incorporate architecture and landscaping into the site land forms, minimize grading impacts, incorporate contour grading and included innovative designs and materials to the extent feasible for the project. Discussion of Modified Grading Permit: Mitigation identified in MND No. 2005-1 would still be applicable to the proposed activity and the changes attributed to the modified grading permit would not result in any new impacts that would substantially damage scenic resources. Grading activities would occur within the same project footprint and result in the same final grading elevations and designs. Therefore, a less than significant impact is identified. This conclusion applies to all three of the haul routes. Finding: Implementation of the modified grading plan would neither negate nor exacerbate the significance of the impact to scenic resources. The impact would remain less than significant regardless of implementation of the proposed activity. There are no new impacts, changes, or La Strada Modified Grading Permit 18 City of Lake Elsinore Canyon Creek Specific Plan February 2010 CC February 09, 2010 Item No. 10 Page 35 of 85 Initial new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. c) Substantially degrade the existing visual character or quality of the site and its surroundings? MND No. 2005-1 Conclusion: Less than Significant. The Final MND prepared for the La Strada Planning Area concluded the project would have a less than significant impact with regard to degradation of the existing visual character or quality of the site and its surroundings (page 27). Discussion of Modified Grading Permit: Grading activities would occur within the same project footprint and result in the same final grading elevations and designs. The project site is currently in a partially-graded condition, and grading activities are anticipated to occur for an additional two months. It will take up to 7 months to process and export the excess graded material. After that time, the proposed development plans (already approved) for the project site would be implemented, which would include construction of home sites. Therefore, the graded landscape that is visible from adjacent residential developments would be a temporary condition and no additional impacts are identified. This conclusion applies to all three haul routes. Finding: Implementation of the modified grading plan would neither negate nor exacerbate the significance of the impact to visual quality. The impact would remain less than significant regardless of implementation of the proposed activity. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. d) Create a new source of substantial light or glare that would adversely affect daytime or nighttime views in the area? MND No. 2005-1 Conclusion: Less than Significant Impact. The Final MND prepared for the La Strada Planning Area concluded the project would have a less than significant impact with regard to lighting and glare (page 28). Discussion ofModifed Grading Permit. The grading operations would occur during daytime and would not require night lighting. Therefore, no issues pertaining to lighting and glare are identified for the modified grading plan. Therefore, a less than significant impact is identified. Use of existing roads as with haul route one and two would not impact light or glare. Similarly, construction of a new haul route (haul route #3) would not create a source of substantial light or glare. Therefore, a conclusion of less than significant applies to all three haul routes. Finding: Implementation of the modified grading plan would neither negate nor exacerbate the significance of the impact to daytime or nighttime views in the area. The impact would remain less than significant regardless of implementation of the proposed activity. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND.

Agricultural Resources - Would the proposed activity: a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non-agricultural use? MAID No. 2005-1 Conclusion: No Impact. The Final MND prepared for the La Strada Planning Area concluded the project would not have an impact to farmland (page 28). Discussion of Modified Grading Permit. Modification of the grading permit would not result in any impacts to prime farmland, unique farmland or farmland of statewide importance since these resources do not occur in the project site. Therefore, no impact is identified. This conclusion applies to all the haul routes. Finding: Because there is no Prime Farmland, Unique Farmland, or Farmland of Statewide Importance in the project area, there are no new impacts for this issue area. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. b) Conflict with existing zoning for agricultural use, or a Williamson Act contract? MND No. 2005-1 Conclusion: No Impact. The Final MND prepared for the La Strada Planning Area concluded the project would not have an impact to areas zoned for agricultural use or held in a Williamson Act contract (page 28). Discussion of Modified Grading Permit. Modification of the grading permit would not result in any impacts to lands zoned for agricultural use or land held under a Williamson Act. There are no Williamson Act contract lands in the project area. The project site is zoned for residential and open space and is already approved for development. Therefore, no impact is identified. This conclusion applies to all the haul routes. Finding: Because there are no agricultural uses or Williamson Act contracts in the planning area, there are no new impacts for this issue area. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. c) Involve other changes in the existing environment which, due to their location or nature, could result in conversion of farmland to non-agricultural use? MND No. 2005-1 Conclusion: No Impact. The Final MND prepared for the La Strada Planning Area concluded the project would not involve other changes in the existing environment which, due to their location or nature, could result in conversion of farmland to non-agricultural use (page 28). Discussion of Modified Grading Permit: Modification of the grading permit would not result in any impacts to lands with an existing zoning for agricultural use or land held under a Williamson Act. There are no Williamson Act contract lands in the project area. The project site is zoned for residential and open space and is already approved for development. Therefore, no impact is identified. This conclusion applies to all the haul routes. La Strada Modified Grading Permit 20 City of Lake Elsinore Canyon Creek Specific Plan February 2010 CC February 09, 2010 Item No. 10 Page 37 of 85 Initial Finding: Because there are no agricultural uses or Williamson Act contracts in the planning area, there are no new impacts for this issue area. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. 3. Air Quality -Would the proposed activity: a) Conflict with or obstruct implementation of the applicable air quality plan? MND No. 2005-1 Conclusion: Less than Significant. The Final MND prepared for the La Strada Planning Area concluded the project would not conflict with, or obstruct, implementation of the applicable air quality plan (page 28). Discussion of Modified Grading Permit. The proposed activity relates to the air quality planning process through the growth forecasts that were used as inputs into the regional transportation model. If a proposed development is consistent with those growth forecasts, and if all available emissions reduction strategies are implemented as effectively as possible on a project-specific basis, then the project is consistent with the Air Quality Management Plan (AQMP). Modifications to the grading plan would not result in an increase in density beyond what is approved for the site. Haul Route 1 is a fully developed road that would not result in any air quality emissions. Haul Route 2 is an improved road that may require implementation of basic dust control measures outlined in mitigation measures III.b-2 through III.b-16. Haul Route 3 requires construction of a new road through an undeveloped area. Construction of this road was contemplated in the La Strada Final MND but not fully analyzed because the final alignment was unknown. As stated in the La Strada Final MND, construction of Haul Route 3 would require additional California Environmental Quality Act (CEQA) analysis to fully address all potential construction impacts. Finding: The proposed modification to the grading permit would not increase the level of intensity of development as originally proposed in the Final MND. The impact to regional air quality plans would remain less than significant regardless of implementation of the proposed activity. Therefore, there are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. b) Violate any air quality standard or contribute substantially to an existing or projected air quality violation? MAD No. 2005-1 Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that with incorporation of mitigation measures (III.b-2 through III.b-16), the project would not violate any air quality standard or contribute substantially to an existing or projected air quality violation (page 31). These mitigation measures call for use of low emissions construction equipment, site watering, use of soil tracking controls for construction vehicles, use of slope stabilizers and seeding to minimize dust generation. Discussion of Modified Grading Permit. An URBEMIS 2007 (version 9.2.4) model run was conducted to estimate the emissions associated with the proposed grading and hauling activities. This analysis was conducted as Final MND 2005-1 did not consider emissions associated with La Strada Modified Grading Permit 21 City of Lake Elsinore Canyon Creek Specific Plan - February 2010 CC February 09, 2010 Item No. 10 Page 38 of 85 Initial materials export. The URBEMIS model output is included as Appendix B. The following assumptions were used for the modeling: • Acres to be graded: 5.04 acres • Volume of exported material (cy): 80,000 cy • Type of equipment: hauling equipment= 16-yard transfer trucks • Processing equipment = rock crusher, sizing screens and conveyor belt system • Loading equipment = front end loader • Grading equipment = bulldozer • Haul distance: average Distance = 30 miles round trip • Truck trips: average 10 trips per day or worst case: one 40-trip day per week • Construction dates: grading -May 2010 to June 2010; grading activity will be five days a week, Monday through Friday from 7:00 AM to 4:30 PM • Hauling -May 2010 to December 2010; hauling activity will be five days per week, 8:00 AM to 4:00 PM. As shown in Table 1, the grading and hauling emissions are below the South Coast Air Quality Management District (SCAQMD) thresholds in both summer and winter and in both the mitigated and unmitigated conditions. The mitigated condition detailed in Table 1 assumes the use of basic dust control measures including watering. Additionally, the activity, as part of the overall La Strada project, will still have to implement mitigation measures III.b-2 through I11.13-16, as applicable, from the Final MND for the La Strada project. Therefore, the changes in grading and hauling activity associated with the modified grading permit would not change the conclusions from the Final MND. Table 1.

For modeling purposes, the following dust control measures were assumed: (1) Watering of exposed surfaces twice daily; (2) Application of soil stabilizers to inactive areas; (3) Stabilizing soil in equipment loading/unloading areas; (4) and managing haul road dust by watering twice daily. La Strada Modified Grading Permit Canyon Creek Specific Plan 22 City of Lake Elsinore February 2010 CC February 09, 2010 Item No. 10 Page 39 of 85 Initial (4) NOx - oxides of nitrous VOC - volatile organic compounds PM - particulate matter SOx - oxides of sulfur Route 1 is a fully developed road that would not result in any air quality emissions. Haul Route 2 is an improved road that may require implementation of basic dust control measures outlined in mitigation measures HI.b-2 through IH.b-16. Haul Route 3 requires construction of a new road through an undeveloped area. Construction of this road was contemplated in the La Strada Final MND but not fully analyzed because the final alignment was unknown. As stated in the La Strada Final MND, construction of Haul Route 3 would require additional CEQA analysis to fully address all potential construction impacts. Finding: Because prescribed mitigation measures from the Final MND (III.b-2 through III.b-16), would be implemented, the air quality modeling data demonstrates that the proposed activity would neither negate nor substantially exacerbate the significance of impacts to air quality if either Haul Routes 1 or 2 were selected. The impact would remain mitigated to below a level of significance. Thus, the previously identified air quality impacts would not be made substantially more severe as a result of the proposed activity and there are no changes or new information that would require the preparation of a Supplemental or Subsequent MND. If Haul Route 3 is selected, a previously undisturbed area would be graded for a road. Emissions analysis for new road construction would be required. Subsequent analysis for air quality would be required and a determination regarding the adequacy of a MND Addendum cannot be made at this time. c) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable Federal or State ambient air quality standard (including releasing emissions exceeding quantitative thresholds for ozone precursors)? MND No. 2005-I Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that with incorporation of mitigation measures (III.b-2 through IR.b-16), the project would not violate any air quality standard or contribute substantially to an existing or projected air quality violation (page 31). Discussion of Modified Grading Permit: The South Coast Air Basin is in non-attainment for federal and state ambient air quality standards for ozone (03), particulate matter less than 10 microns in size (PMro), and carbon monoxide (CO). As shown in Table 1 above, the proposed grading and hauling activities would not result in emissions greater than the SCAQMD thresholds for construction for either of these criteria pollutants. In addition, the proposed activity, as part of the La Strada project, will still have to implement mitigation measures III.b-2 through III.b-16, as applicable, from the Final MND for the La Strada project. The conclusion from the Final MND regarding cumulative impacts remains applicable. Haul Route 1 is a fully developed road that would not result in any air quality emissions. Haul Route 2 is an improved road that may require implementation of basic dust control measures outlined in MM III.b-2 through MM III.b-16. Haul Route 3 requires construction of a new road through an undeveloped area. Construction of this road was contemplated in the La Strada Final MND but not fully analyzed because the final alignment was unknown. Construction of Haul 'La Strada Modified Grading Permit 23 City of Lake Elsinore Canyon Creek Specific Plan February 2010 CC February 09, 2010 Item No. 10 Page 40 of 85 Initial Route 3 would require additional CEQA analysis to fully address all potential construction impacts. Finding: Because prescribed mitigation measures from the Final MND (IR.b-2 through HI.b-16), would be implemented, the air quality modeling data demonstrates that the proposed activity would neither negate nor substantially exacerbate the significance of cumulative impacts to air quality if Haul Routes 1 or 2 were selected. The impact would remain mitigated to below a level of significance. Thus, the previously identified air quality impacts would not be made substantially more severe as a result of the proposed activity and there are no changes or new information that would require the preparation of a Supplemental or Subsequent MND. If Haul Route 3 is selected, a previously undisturbed area would be graded for a road. Emissions analysis for new road construction would be required. Subsequent analysis for air quality would be required and a determination regarding the adequacy of a MND Addendum cannot be made at this time. d) Expose sensitive receptors to substantial pollutant concentrations? MND No. 2005-I Conclusion: Less than Significant with Mitigation Incorporation The Final MND prepared for the La Strada Planning Area concluded that with incorporation of mitigation measures (HI.b-2 through IH.b-16), the project would adequately control fugitive dust and was not forecast to expose sensitive receptors to significant fugitive dust pollution. No other emissions pose a potential for exposure to substantial pollutant concentrations (page 31). Discussion of Modified Grading Permit: The project site has existing residential development to the east. Additionally, depending on the haul route selected (Haul Routes 1 and 2); the haul trucks may pass through portions of a residential neighborhood. As noted in response 3.b., the proposed activity will not exceed any of the thresholds for pollutants, thus there is not a potential to expose sensitive receptors to significant emissions. Mitigation measures identified for fugitive dust in the original Final MND would remain a requirement of this project. This conclusion applies to all the haul routes. Finding: Because prescribed mitigation measures from the Final MND (III.b-2 through III.b-16), would be implemented, the proposed activity would neither negate nor substantially exacerbate the significance of air quality impacts to sensitive receptors. The impact would remain mitigated to below a level of significance. Thus, the previously identified air quality impacts would not be made substantially more severe as a result of the proposed activity and there are no changes or new information that would require the preparation of a Supplemental or Subsequent MND. e) Create objectionable odors affecting a substantial number of people? MAD No. 2005-I Conclusion: Less than Significant. The Final MND for the La Strada Planning Area noted that the project could include activities that would have diesel and asphalt odors; however, those odors were determined to be short-term and less than significant (page 32). Discussion of Modified Grading Permit: Grading equipment used could include diesel fuel odors, however, these will continue to be short term activities (two months for grading and seven months for hauling), and no additional impact is identified beyond that already identified in the Final MND for the La Strada project. This conclusion applies to all the haul routes. La Strada Modified Grading Permit 24 City of Lake Elsinore Canyon Creek Specific Plan February 2010 CC February 09, 2010 Item No. 10 Page 41 of 85 Initial Finding: The potential for a short-term odor impact would remain less than significant regardless of implementation of the proposed activity. Therefore, there are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. 4. Biological Resources - Would the proposed activity: a) Have a substantial adverse effect, either directly or indirectly or through habitat modification, on any species identified as a candidate, sensitive, or special status in local or regional plans, policies, or regulations, or by the California Department of Fish and Game or U.S Fish and Wildlife Service? MND No. 2005-I Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that with incorporation of a mitigation measure (fV.a-1) the project would have a less than significant impact to any species identified as a candidate, sensitive, or special status in local or regional plans, policies, or regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service. The mitigation requires the permanent preservation of 75.5 acres of habitat as open space (page 33). Discussion of Modified Grading Permit. Since the proposed activity grading falls within the development footprint considered in the Final MND, no new significant impacts from the grading related to sensitive biological resources are identified. If Haul Routes I or 2 are selected for soils export, then the impact to biological resources would remain mitigated to below a level of significance. Therefore, there are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. If Haul Route 3 is selected, a previously undisturbed area would be graded for a road. Construction of this road was contemplated in the La Strada Final MND but not fully analyzed because the final alignment was unknown. As stated in the La Strada Final MND, construction of Haul Route 3 would require additional CEQA analysis to fully address all potential construction impacts. Therefore a determination regarding the adequacy of a MND Addendum cannot be made at this time. Finding: If Haul Routes I or 2 are selected, the previously identified biological resource impacts would not be made substantially more severe as a result of the proposed activity and there are no changes or new information that would require the preparation of a Supplemental or Subsequent MND. However, If Haul Route 3 is selected an additional CEQA analysis to fully address all potential construction impacts shall be conducted. Therefore, a determination regarding the adequacy of a MND Addendum for Haul Route 3 cannot be made at this time. b) Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, or regulations, or by the California Department of Fish and Game or the U.S. Fish and Wildlife Service? MAD No. 2005-I Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that with incorporation of a mitigation measure (IV.b-1) the project would have a less than significant impact effect on any riparian La Strada Modified Grading Permit 25 City of Lake Elsinore Canyon Creek Specific Plan February 2010 CC February 09, 2010 Item No. 10 Page 42 of 85 Initial habitat or other sensitive natural community identified in local or regional plans, policies, or regulations, or by the California Department of Fish and Game or the U.S. Fish and Wildlife Service. The mitigation requires the creation of 0.04 acre of non-wetland waters of the U.S. and 0.12 acre of CDFG jurisdictions southern willow scrub (page 33). Discussion of Modifted Grading Permit: Since the proposed activity grading falls within the development footprint considered in the Final MND, no new significant impacts from the grading related to sensitive riparian habitats are identified. If Haul Routes 1 or 2 are selected for soils export, then the impact to riparian or sensitive habitats would remain mitigated to below a level of significance. Therefore, there are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. If Haul Route 3 is selected, a previously undisturbed area would be graded for a road. Construction of this road was contemplated in the La Strada Final MD but not fully analyzed because the final alignment was unknown. As stated in the La Strada Final MND, construction of Haul Route 3 would require additional CEQA analysis to fully address all potential construction impacts. Therefore a determination regarding the adequacy of a MND Addendum cannot be made at this time. Finding: If Haul Routes 1 or 2 are selected, the previously identified impacts to riparian and sensitive habitats would not be made substantially more severe as a result of the proposed activity and there are no changes or new information that would require the preparation of a Supplemental or Subsequent MND. However, if Haul Route 3 is selected an additional CEQA analysis to fully address all potential construction impacts shall be conducted. Therefore, a determination regarding the adequacy of a MND Addendum for Haul Route 3 cannot be made at this time. c) Have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? See discussion under IV.b, above. d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native or resident migratory wildlife corridors, or impede the use of native wildlife nursery sites? MND No. 2005-1 Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that with incorporation of a mitigation measure (IV.a-1) the project would have a less than significant impact on the movement of any native resident or migratory fish or wildlife species or with established native or resident migratory wildlife corridors, or impede the use of native wildlife nursery site (page 34). The mitigation requires the permanent preservation of 75.5 acres of habitat as open space, which has already been implemented. Discussion of Modifted Grading Permit: The proposed activity would be required to implement previously approved mitigation measures. Additionally, since the proposed activity grading falls La Strada Modified Grading Permit 26 City of Lake Elsinore Canyon Creek Specific Plan February 2010 CC February 09, 2010 Item No. 10 Page 43 of 85 Initial within the development footprint considered in the Final MND, no new significant impacts from the grading related to the movement of any native resident or migratory fish or wildlife species or with established native or resident migratory wildlife corridors, or impede the use of native wildlife nursery sites are identified. If Haul Routes I or 2 are selected for soils export, then the impact to the movement of any native resident or migratory fish or wildlife species or with established native or resident migratory wildlife corridors, or impede the use of native wildlife nursery sites riparian or sensitive habitats would remain mitigated to below a level of significance. Therefore, there are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. If Haul Route 3 is selected, a previously undisturbed area would be graded for a road. Construction of this road was contemplated in the La Strada Final MND but not fully analyzed because the final alignment was unknown. As stated in the La Strada Final MND, construction of Haul Route 3 would require additional CEQA analysis to fully address all potential construction impacts. Therefore, a determination regarding the adequacy of a MND Addendum with regard to the movement of any native resident or migratory fish or wildlife species or with established native or resident migratory wildlife corridors, or impede the use of native wildlife nursery sites cannot be made at this time. Finding: Under Haul Routes I or 2, the previously identified impacts to wildlife movement would not be made substantially more severe as a result of the proposed activity and there are no changes or new information that would require the preparation of a Supplemental or Subsequent MND. If Haul Route 3 is selected, an additional CEQA analysis to fully address all potential construction impacts would be required. Therefore a determination regarding the adequacy of a MND Addendum cannot be made at this time. e) Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? MND No. 2005-1 Conclusion: No Impact. The Final MND prepared for the La Strada Planning Area concluded that the project would not conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance (page 34). Discussion of Modified Grading Permit: The City does not have a tree preservation policy or ordinance. Therefore, no impact is identified. This conclusion applies to all the haul routes. Finding: Because the proposed activity would not conflict with City policies or ordinances, there are no new impacts identified for this issue area. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. fl Conflict with the provisions of an adopted habitat conservation plan, natural community conservation plan, or other approved local, regional, or State habitat conservation plan? MND No. 2005-1 Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that with incorporation of a mitigation measure (N.a-I and iV.b-1) the project would have a less than significant impact with regard to La Strada Modified Grading Permit 27 City of Lake Elsinore Canyon Creek Specific Plan February 2010 CC February 09, 2010 Item No. 10 Page 44 of 85 Initial conflict with the provisions of the Multiple Species Habitat Conservation Plan (MSHCP). The Final MND concluded that the project was consistent with the MSHCP (page 34). Discussion ofModifted Grading Permit: Because the proposed activity falls within the development footprint considered in the Final MND, no new significant impacts related to a conflict with the MSHCP are identified. Mitigation identified in the Final MND would still be applicable. Therefore, a less than significant impact with mitigation is identified. Additionally, hauling under Haul Routes 1 and 2 would occur on existing disturbed areas. Hauling under Route 3 would require the construction of a new road through undisturbed areas; however, those areas were analyzed in the Final MND for the La Strada project and the road was considered in the MSHCP, and no additional impacts would occur due to the modification of the grading plan. Finding: Because prescribed mitigation measures from the Final MND (fV.a-1 and IV.b-1) would be implemented, the proposed activity would neither negate nor substantially exacerbate the significance of biological resource impacts. The impact would remain mitigated to below a level of significance. Thus, the previously identified biological resource impacts would not be made substantially more severe as a result of the proposed activity and there are no changes or new information that would require the preparation of a Supplemental or Subsequent MND. 5. Cultural Resources -Would the proposed activity: a) Cause a substantial adverse change in the significance of a historical resource as defined in §15064.5? MND No. 2005-1 Conclusion: Less Than Significant Impact. The Final MND prepared for the La Strada Planning Area concluded the project would have a less than significant impact to historic resources (page 34). Discussion of Modified Grading Permit: Grading activities would occur within the area analyzed in Final MND 2005-1, thus no new impact related to grading would occur with the proposed activity. Hauling under Routes 1 and 2 would occur within existing roadways, thus there would be no impact to historical resources, as any potential disturbance to historical resources would have already occurred. Hauling under Route 3 would require the construction of a new road through an area that has not been analyzed for historical resources. Therefore, with regard to Route 3, additional analysis would be required to determine if there is a potential to impact historical resources. Finding: If Haul Routes 1 or 2 are selected for soils export, then the impact to historical resources would remain less than significant. Therefore, there are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. If Haul Route 3 is selected, a previously undisturbed area would be graded for a road. Subsequent analysis for historical resources would be required and a determination regarding the adequacy of a MND Addendum for purposes of Haul Route 3 cannot be made at this time. b) Cause a substantial adverse change in the significance of an archaeological resource pursuant to §15064.5? La Strada Modified Grading Permit 28 City of Lake Elsinore Canyon Creek Specifc Plan February 2010 CC February 09, 2010 Item No. 10 Page 45 of 85 Initial Study MND No. 2005-1 Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that with incorporation of mitigation measures (V.b-1 and V.b-3), the project would have a less than significant impact to archaeological resources (page 35). These mitigation measures call for the stopping of construction activity if cultural materials or human remains are encountered during construction. Discussion of Modified Grading Permit: Grading activities would occur within the area analyzed in Final MND 2005-1, thus no new impact related to grading would occur with the proposed activity. Hauling under Routes 1 and 2 would occur within existing roadways, thus there would be no impact to archaeological resources, as any potential disturbance to historical resources would have already occurred. Hauling under Route 3 would require the construction of a new road through an area that has not been analyzed for archaeological resources. Therefore, with regard to Haul Route 3, additional analysis would be required to determine if there is a potential to impact archaeological resources. Finding: If Haul Routes 1 or 2 are selected for soils export, then the impact to archaeological resources would remain less than significant. Therefore, there are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. If Haul Route 3 is selected, a previously undisturbed area would be graded for a road. Subsequent analysis for archaeological resources would be required and a determination regarding the adequacy of a MND Addendum for purposes of Haul Route 3 cannot be made at this time. c) Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature? MAD No. 2005-1 Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that with incorporation of mitigation measure (V.b-2) the project would have a less than significant impact to paleontological resources (page 35). This mitigation measure calls for the stopping of construction activity if paleontological materials are encountered during construction. Discussion of Modified Grading Permit: Mitigation identified in the Final MND would still be applicable to the proposed activity. Grading activities would occur within the area analyzed in Final MND 2005-1, thus no new impact related to grading would occur with the proposed activity. Hauling under Routes I and 2 would occur within existing roadways, thus there would be no impact to paleontological resources, as any potential disturbance to paleontological resources would have already occurred. Hauling under Haul Route 3 would require the construction of a new road through an area that has not been analyzed for paleontological resources. Therefore, with regard to Route 3, additional analysis would be required to determine if there is a potential to impact paleontological resources. Finding: If Haul Routes 1 or 2 are selected for soils export, then the impact to paleontological resources would remain less than significant. Therefore, there are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. La Strada Modified Grading Permit 29 City of Lake Elsinore Canyon Creek Specific Plan February 2010 CC February 09, 2010 Item No. 10 Page 46 of 85 Initial If Haul Route 3 is selected, a previously undisturbed area would be graded for a road. Subsequent analysis for paleontological resources would be required and a determination regarding the adequacy of a MND Addendum cannot be made at this time. d) Disturb any human remains, including those interred outside offormal cemeteries? MND No. 2005-1 Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that with incorporation of a mitigation measure (V.b-3) the project would have a less than significant impact with regard to human remains (page 35). This mitigation measure calls for the stopping of construction activity if human remains are encountered during construction. Discussion ofModifled Grading Permit. Mitigation V.b-3 identified in the Final MND would still be applicable to the proposed activity. Grading activities would occur within the area analyzed in Final MND 2005-1, thus no new impact related to grading would occur with the proposed activity. Hauling under Routes I and 2 would occur within existing roadways, thus there would be no impact to human remains, as any potential disturbance to human remains would have already occurred. Hauling under Route 3 would require the construction of a new road through an area that has not been analyzed for human remains. Therefore, with regard to Route 3, additional analysis would be required to determine if there is a potential to impact human remains interred outside of a formal cemetery. Finding: If Haul Routes 1 or 2 are selected for soils export, then the potential impact to human remains outside formal cemeteries would remain less than significant. Therefore, there are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. If Haul Route 3 is selected, a previously undisturbed area would be graded for a road. Subsequent analysis for cultural resources would be required and a determination regarding the adequacy of a MND Addendum for purposes of Haul Route 3 cannot be made at this time. 6. Geology and Soils -Would the proposed activity: a) Expose people or structures to potential adverse effects, including risk of loss, injury, or death involving. i) Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault? MND No. 2005-1 Conclusion: Less Than Significant Impact. The Final MND prepared for the La Strada Planning Area concluded the project would have a less than significant impact with regard to rupture of known earthquake faults (page 35). Discussion of Modified Grading Permit. Based upon review of the Draft Lake Elsinore General Plan Update (2009) and Alquist-Priolo Earthquake Fault Zoning Maps, the project site is not located on a known fault. The Elsinore fault runs approximately two miles west of the project site. Therefore, a less than significant impact is identified. This conclusion applies to each of the three hauling routes. La Strada Modified Grading Permit 30 City of Lake Elsinore Canyon Creek Specific Plan February 2010 CC February 09, 2010 Item No. 10 Page 47 of 85 Initial Finding: Because the planning area does not fault within an Alquist-Priolo fault zone, the impact would remain less than significant regardless of implementation of the proposed activity. Therefore, there are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent NMD. ii) Strong seismic ground shaking? MND No. 2005-1 Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that with incorporation of mitigation measure (VI.a-1), which identified specific foundation and structure requirements for future structures on the site, impacts related to seismic ground shaking would be less than significant (page 36). Discussion of Modified Grading Permit: The changes with the grading permit address export of material that was not previously considered; it does not address any changes to how future residential structures will be built on the project site. Future development on the site would still be required to adhere to the mitigation measures identified in Final MND 2005-1. The proposed changes in the grading plan would not result in an impact related to this issue area. Therefore, a less than significant impact is identified. This conclusion applies to each of the three hauling routes. Finding: Because prescribed mitigation measures from the Final MND (VI.a-1), would be implemented, the proposed activity would neither negate nor substantially exacerbate the significance of impacts related to seismic ground shaking. The impact would remain mitigated to below a level of significance. Thus, the previously identified seismic impact would not be made substantially more severe as a result of the proposed activity and there are no changes or new information that would require the preparation of a Supplemental or Subsequent MND. iii) Seismic-related ground failure, including liquefaction? MND No. 2005-1 Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that the project site is not located within a liquefaction zone. The Final MND also noted that with incorporation of a mitigation measure (VI.a-2), which requires adherence to the geotechnical recommendations within a comprehensive geotechnical analysis, impacts would be less than significant (page 36). Discussion of Modified Grading Permit: The modified grading plan would not result in any changes that would impact the site's susceptibility for liquefaction. The General Plan Update (City of Lake Elsniore 2009) includes liquefaction zones from the Riverside County Integrated Project. On this map, the La Strada planning area is identified has having a very low risk of liquefaction. Therefore, a less than significant impact is identified. This conclusion applies to all three haul routes. Finding: Because prescribed mitigation measures from the Final NIND (VI.a-2) would be implemented, the proposed activity would neither negate nor substantially exacerbate the significance of impacts related to liquefaction. The impact would remain mitigated to below La Strada Modified Grading Permit 31 City of Lake Elsinore Canyon Creek Specific Plan February 2010 CC February 09, 2010 Item No. 10 Page 48 of 86 Initial a level of significance. Thus, the previously identified liquefaction impact would not be made substantially more severe as a result of the proposed activity and there are no changes or new information that would require the preparation of a Supplemental or Subsequent MND. iv) Landslides? MND No. 2005-1 Conclusion: Less than Significant Impact. The Final MND prepared for the La Strada Planning Area noted that no landslides were mapped during the field reconnaissance and no ancient landslides are known to exist on the project site (page 36). Therefore, a less than significant impact was identified. Discussion ofModifted Grading Permit: Grading activities under the modified grading plan would not increase the potential for landslides. Therefore, a less than significant impact is identified. This conclusion is consistent regardless of which of the three hauling routes is used. Finding: Because the modification to the grading plan to include the export of fill would not affect the potential for landslides to occur, the impact related to landslides would remain less than significant regardless of implementation of the proposed activity. Therefore, there are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. b) Result in substantial soil erosion or loss of topsoil? MAD No. 2005-1 Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that, as with any development, soil erosion can result during construction, as grading and construction can loosen surface soils and make soils susceptible to effect of wind and water movements. Mitigation was identified (VI.b-1), which reduced this impact to below a level of significance (page 36). The mitigation measures calls for implementation of best management practice that are identified in the Storm Water Pollution Prevention Plan (SWPPP) for the project. Discussion of Modified Grading Permit: Because the grading permit modifications focus on the export of excess materials, the modification would not change grading activities in a manner that would increase soil erosion or the loss of topsoil. The proposed activity would still be required to implement best management practices identified in the SWPPP. Additionally, mitigation measures identified for air quality, which require dampening of soils to minimize loss of soil by wind-driven forces would be still be required to be implemented under the proposed activity and would further help to minimize soil loss. Thus, no change in impact is identified. This conclusion would remain the same for each of the haul routes. Finding: Because prescribed mitigation measures from the Final MND (VI.b-1) would be implemented, the proposed activity would neither negate nor substantially exacerbate the significance of impacts associated with soil erosion. The impact would remain mitigated to below a level of significance. Thus, the previously identified impact related to soil erosion would not be made substantially more severe as a result of the proposed activity and there are no changes or new information that would require the preparation of a Supplemental or Subsequent MND. La Strada Modified Grading Permit 32 City of Lake Elsinore Canyon Creek Specific Plan - February 2010 CC February 09, 2010 Item No. 10 Page 49 of 85 Initial c) Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the proposed activity, and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction, or collapse? MAD No. 2005-1 Conclusion: Less than Significant Impact. The Final MND prepared for the La Strada Planning Area concluded that no adverse effects related to site stability were identified for the project (page 37). Based upon the bedrock and topsoil type on the project site, there is a low potential for on- or off-site landslide, lateral spreading, subsidence, liquefaction, or collapse. Discussion of Modified Grading Permit. Since bedrock conditions have not changed for the project site, grading activities under the modified grading plan would not increase the potential for on- or off-site landslide; lateral spreading, subsidence, liquefaction, or collapse. Therefore, a less than significant impact is identified. This conclusion is consistent regardless of which of the three hauling routes is used. Finding: Because grading activities under the modified grading plan would not increase the potential for on- or off-site landslide, lateral spreading, subsidence, liquefaction, or collapse, the related geological impacts would remain less than significant regardless of implementation of the proposed activity. Therefore, there are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. d) Be located on expansive soils, as defined in Table 18-1-b of the Uniform Building Code (UBC) creating substantial risks to life or property? MAD No. 2005-1 Conclusion: Less than Significant Impact. The Final MND prepared for the La Strada Planning Area concluded that the soils on the project site were not identified in the technical studies prepared for the project as expansive soils, as defined by Table 18-1-B of the UBC. Therefore, a less than significant impact was identified. Discussion of Specific Plan Amendment: Since bedrock and soils conditions have not changed for the project site, grading activities under the modified grading plan would not result in an increase in risk related to expansive soils. Therefore, a less than significant impact is identified. This conclusion is consistent regardless of which of the three hauling routes is used. Finding: Because grading activities under the modified grading plan would not result in an increase in risk related to expansive soils, the related geological impacts would remain less than significant regardless of implementation of the proposed activity. Therefore, there are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. e) Have soils incapable of adequately supporting the use of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal of wastewater? MND No. 2005-1 Conclusion: No Impact. The Final MND prepared for the La Strada Planning Area concluded that the soils on the project site were not capable of supporting septic tanks unless engineering modifications were made. However, the La Strada project did not propose septic tanks; rather, the project would connect to the Elsinore Valley Municipal Water District (EVMWD) wastewater collection and treatment system (page 37). La Strada Modified Grading Permit 33 City of Lake Elsinore Canyon Creek Specific Plan February 2010 . CC February 09, 2010 Item No. 10 Page 50 of 85 Initial Discussion of Modified Grading Permit. The modified grading plan does not change the proposed wastewater treatment approach for the La Strada project. The future residences would still connect to EVMWD wastewater collection and treatment system. Thus, no changes to the conclusion from Final MND 2005-1 are identified for the proposed activity and no impact is identified. This conclusion applies to all three hauling routes. Finding: Because the modified grading plan would not change the proposed wastewater treatment approach for the La Strada project, there would continue to be no impact to the capacity of soils to handle septic tanks or alternative wastewater disposal systems as a result of the proposed activity. Therefore, there are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. 7. Greenhouse Gas Emissions -Would the proposed activity: According to CEQA Guidelines Section 15002(a)(1), one of the basic purposes of CEQA is to, "inform governmental decision makers and the public about the potential significant environmental effects of proposed actions." Pursuant to SB 97 discussion of global warming impacts is newly required by CEQA Statutes and Guidelines. The earth's atmospheric greenhouse gases (GHGs) and clouds influence the earth's temperature by absorbing infrared radiation (heat) rising from the earth's sun-warmed surface that would otherwise escape into space. The process is commonly known as the Greenhouse Effect. Release of GHGs into the atmosphere enhances the Greenhouse Effect causing temperature to increase. The GHGs responsible for increasing the Greenhouse Effect and their relative contribution to the rise in temperatures include carbon dioxide (CO2); methane (CHA near- surface ozone (03); nitrous oxide (N2O); and chlorofluorocarbons (CFCs). These GHGs are primarily associated with the burning of fossil fuels (during transport, electricity generation, industry, manufacturing, etc.), deforestation, agricultural activity and gases from solid waste disposal. The most common GHG by volume is CO2, which constitutes approximately 84 percent of all GHG emissions in California. Worldwide, the State of California ranks as the 16`6 largest emitter of CO2 and is responsible for approximately 2 percent of the world's CO2 emissions (CEC 2006a). The State Legislature adopted the public policy position that global warming is, "a serious threat to the economic well being, public health, natural resources, and the environment of California" (Health and Safety Code Section 38501). Further, the State Legislature has determined that "potential adverse impacts of global warming include the exacerbation of air quality problems, a reduction in the quality and quantity of water to the state from the Sierra snow pack, a rise in sea levels resulting in the displacement of thousands of coastal businesses and residences, damage to marine ecosystems and the natural environment, and an increase in the incidences of infectious disease, asthma, and other human health related problems", and that "global warming will have detrimental effects on some of California's largest industries, including agriculture, wine, tourism, skiing, recreational and commercial fishing, and forestry [and] ...will also increase the strain on electricity supplies necessary to meet the demand for summer air-conditioning in the hottest parts of the state" (Health and Safety Code Section 38501). These public policy statements became law with the enactment of AB 32, Statutes of 2006. La Strada Modified Grading Permit 34 City of Lake Elsinore Canyon Creek Specific Plan February 2010 CC February 09, 2010 Item No. 10 Page 51 of 85 Initial a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment? MND No. 2005-1: No analysis. The previous document did not analyze greenhouse gas emissions. Discussion of Modified Grading Permit: The modified grading plan would generate greenhouse gas emissions through the use of diesel trucks during the grading and hauling activities. The amount of C02 was calculated using EMFAC2007. The following assumptions were made: • Acres to be graded: 5.04 acres • Volume of exported material (cy): 80,000 cy • Type of Equipment: Hauling equipment = 16-yard transfer trucks • Processing equipment = rock crusher, sizing screens and conveyor belt system; • Loading equipment = front end loader • Grading equipment = bulldozer • Haul Distance: Average Distance = 30 miles round trip • Truck Trips: Average 10-trips per day or worst case: one 40 trip day per week. • Construction Dates: Grading - May 2010 to June 2010; grading activity will be five days a week, Monday through Friday from 7:30 AM to 4:30 PM • Hauling -May 2010 to December 2010; hauling activity will be five days per week from 8:00 AM to 4:00 PM. The C02 outputs were run for idling (0 mph) and for an assumed average highway speed of 55 mph, only for heavy-duty diesel trucks (HDT). The following table provides the C02 emissions calculated for the proposed activity. Note that the idling (0 mph) emission factor is in units of grams/hour of idle time, whereas the highway speed (55 mph) emission factor is in units of grams/mile travelled. Table 2: C02 Emission Factors Speed C02 Emission Factor 0 mph (idling) 6748.317 grams/hour (357.05 Ibs/day) 55 mph 1621.747 grams/mile (4,290 Ibs/day) Source: EMFAC2007 The incremental increase in C02 emissions as a result of the modified grading plan is presumed to be less than significant given that the use of diesel trucks is only for the duration of construction related activities and is considered to be a temporary impact. Neither the City nor the South Coast Air Quality Management District (SCAQMD) has adopted standards to provide a quantitative comparison or threshold. As shown in Table 1, the grading and hauling emissions for criteria pollutants (which includes ozone precursors and nitrous oxides) are below the SCAQMD thresholds in both summer and winter and in both the mitigated and unmitigated La Strada Modified Grading Permit Canyon Creek Specific Plan 35 City of Lake Elsinore February 2010 CC February 09, 2010 Item No. 10 Page 52 of 85 Initial Study conditions. The mitigated condition detailed in Table 1 assumes the use of basic dust control measures including watering. Additionally, the proposed activity will still have to implement mitigation measures III.b-2 through III.b-16, as applicable, from the Final MND for the La Strada project. These mitigation measures call for use of low emissions construction equipment, site watering, use of soil tracking controls for construction vehicles, use of slope stabilizers and seeding to minimize dust generation. This analysis applies to all haul routes. Finding: Based upon the analysis prepared, the greenhouse gas emissions would be less than significant. This issue area was not addressed in Final MND 2005-1, since this topic was not required to be addressed. The analysis presented herein concludes that there would not be any new significant impacts. b) Conflict with any applicable plan, policy or regulation of an agency adopted for the purpose of reducing the emissions of greenhouse gases? MND No. 2005-1: No analysis. The previous document did not analyze greenhouse gas emissions. Discussion of Modified Grading Permit. The City is currently in the process of preparing a climate action plan that will address greenhouse gas emissions inventory within the city. As mentioned in Section 3, Air Quality, modifications to the grading plan would not result in an increase in density beyond what is approved for the site. Therefore, the modified grading plan would not conflict with any applicable plans or policies. In addition, the proposed activity, as part of the La Strada project, would still have to implement mitigation measures III.b-2 through III.b-16, as applicable, from the Final MND for the La Strada project. Therefore, impacts are determined to be less than significant. This conclusion applies to all three haul routes. Finding: Based upon the analysis prepared, the greenhouse gas emissions would be less than significant. This issue area was not addressed in Final MND 2005-1, since this topic was not required to be addressed. The analysis presented herein concludes that there would not be any new significant impacts. 8. Hazards and Hazardous Materials -Would the proposed activity: a) Create a significant hazard to the public or the environment through the routine transport, use or disposal of hazardous materials? MND No. 2005-1 Conclusion: No Impact. The Final MND prepared for the La Strada Planning Area concluded that the project would not create a significant hazard to the public or the environment through the routine transport, use or disposal of hazardous materials (page 37). Discussion of Modified Grading Permit. The modified grading plan for the proposed activity includes export of soils materials from the project site. Depending on the hauling route selected, some of the routes include hauling materials go through portions of residential neighborhoods (Haul Routes 1 and 2). However, the soil material being hauled would not be characterized as a hazardous material. Therefore, a less than significant impact is identified for this issue area. This conclusion would apply to all three hauling routes. La Strada Modified Grading Permit Canyon Creek Specific Plan 36 City of Lake Elsinore February 2010 CC February 09, 2010 Item No. 10 Page 53 of 85 Initial Finding: Because the proposed activity would not result in transporting hazardous materials, there are no new impacts identified for this issue area. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. b) Create a significant harm to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? MND No. 2005-1 Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that with incorporation of a mitigation measure (VII.b-1), the project would reduce impacts related to potential release of hazardous materials to the environment (page 37). Such materials identified in the analysis included household quantities of cleaners or petroleum products from construction activities. Mitigation measure VII.b-lcalled for the containments of any spilled or leaking petroleum products and that any hazardous material is disposed of at a properly licensed disposal or treatment facility. Discussion ofModifted Grading Permit: Grading activities are not typically characterized as an activity that would create significant harm to the public or the environment through reasonably foreseeable upset and accident. The proposed activity includes modification to the grading permit to allow for the export of fill material and would not change proposed land uses. In addition, VII.b-1 would continue to apply to the proposed activity. Further the proposed activity would adhere to the mitigation measures identified in the Final EIR. Therefore, no new impact is identified for this issue area. This conclusion applies to all three hauling routes. Finding: Because prescribed mitigation measures from the Final MND (VII.b-1) would be implemented, the proposed activity would neither negate nor substantially exacerbate the significance of impacts related to the release of hazardous materials into the environment. The impact would remain mitigated to below a level of significance. Thus, the previously identified hazardous materials impacts would not be made substantially more severe as a result of the proposed activity and there are no changes or new information that would require the preparation of a Supplemental or Subsequent MND. c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? MND No. 2005-1 Conclusion: No Impact. The Final MND prepared for the La Strada Planning Area noted that the Tuscany Hills Community Park and Tuscany Hills Elementary School are within ''A mile from the project site. However, the analysis concluded that the neither the proposed use nor construction activities pose a potential to generate significant hazards emissions as part of the project (page 37). Discussion of Modified Grading Permit: Tuscany Hills Elementary school is located approximately 1/4 mile to the east of the proposed grading area. Under Haul Route 2, trucks would pass along Bella Vista adjacent to a portion of Tuscany Hills Community Park, but would not pass by the school. As noted in response 3.b., the proposed activity will not exceed any of the thresholds for pollutants, thus there is not a potential to expose sensitive receptors to significant emissions. Mitigation measures identified for fugitive dust in the original Final MND would remain a requirement of this proposed activity. Therefore, no new impacts are identified. La Strada Modified Grading Permit 37 City of Lake Elsinore Canyon Creek Specific Plan February 2010 CC February 09, 2010 Item No. 10 Page 54 of 85 Initial Finding: Because the proposed activity would not result in the emission of hazardous materials within '/a mile of a school site, there are no new impacts identified for this issue area. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. d) Be on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code 675962.5 and, as a result, would it create a significant hazard for people residing or working in the project area? MND No. 2005-I Conclusion: No Impact. The Final MND prepared for the La Strada Planning Area determined that the project is not located on any hazardous materials sites compiled pursuant to Government Code Section 65962.5 (page 38) and no impact was identified for this issue area. Discussion of Modified Grading Permit. Due to the passage of time, and updated hazards database search was conducted by Environmental Data Research (EDR) (January 2010) for the proposed grading sites. The search results are included as Appendix C of this document. As identified in the search, the project site is not identified as a hazardous materials site of concern. Therefore, no impact is identified for this issue area and the conclusions of the Final MND remain consistent. This conclusion applies to all three haul routes. Finding: Because the proposed activity site is not identified as a hazardous site of concern, there are no new impacts identified for this issue area. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. e) For a project located within an airport land use plan or, where such a plan has been adopted, within 2 miles of a public airport, would the project result in a safety hazard for people residing or working in the project area? MND No. 2005-I Conclusion: No Impact. The Final MND prepared for the La Strada Planning Area determined that the project is not located within an airport land use plan area or within two miles of a public airport or public use airport (page 38). Thus, no impacts were identified for this issue area. Discussion of Modified Grading Permit: No changes to the existing conditions with regard to airport land use plans or public airstrips has been identified. No new public air strips or airport land use plans covering the project site have been identified since certification of Final MND 2005-1. Therefore, no new impact is identified. This conclusion applies to all three haul routes. Finding: Because the proposed activity site is not located within an airport land use plan area or within two miles of an airport, there are no new impacts identified for this issue area. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. La Strada Modified Grading Permit Canyon Creek Specific Plan 38 City of Lake Elsinore February 2010 CC February 09, 2010 Item No. 10 Page 55 of 85 Initial J) For a project within the vicinity of a private airstrip, would the project result in a safety hazard for people residing or working in the project area? MAD No. 2005-1 Conclusion: No Impact. The Final MND prepared for the La Strada Planning Area determined that the project is not located in the vicinity of a private airstrip (page 38). Thus, no impacts were identified for this issue area. Discussion ofModifzed Grading Permit. No changes to the existing conditions with regard to private airstrips have been identified. No new private airstrips in the vicinity of the project site have been identified since certification of Final MND 2005-1. Therefore, no new impact is identified. This conclusion applies to all three haul routes. Finding: Because the proposed activity site is not located within the vicinity of a private air strip, there are no new impacts identified for this issue area. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. g) Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan? AND No. 2005-1 Conclusion: Less than Significant Impact The Final MND prepared for the La Strada Planning Area noted that there are no known emergency response plans or emergency evacuation plans applicable to the project site. Therefore, impacts were determined to be less than significant (page 38). Discussion of Modified Grading Permit. Since preparation of the Final MND, no new emergency response plans have been developed that would be impacted by the modified grading plan. Haul trucks would adhere to all traffic regulations, including yielding to emergency vehicles. No street closures would be required due to the proposed activity. Therefore, no additional impact is identified due to the modified grading permit. This conclusion applies to all three haul routes. Finding: Because the proposed activity would not conflict with and emergency response plan, there are no new impacts identified for this issue area. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. Iz) Expose people or structures to a significant risk of loss, injury or death involving wildland fires, including where wildlands are adjacent to urbanized area or where residences are intermixed with wildlands? MAD No. 2005-1 Conclusion: Less than Significant Impact with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area noted that with incorporation of design features as part of the conditions of project approval, the La Strada project would reduce impacts related to loss, injury and risk from wildlife fires to below a level of significance (page 38). These design features included incorporation of fuel modification zones to provide adequate setbacks from vegetative fuel La Strada Modified Grading Permit Canyon Creek Specific Plan 39 City of Lake Elsinore February 2010 CC February 09, 2010 Item No. 10 Page 56 of 85 Initial Discussion of Modified Grading Permit: The modifications to the grading plan include export of materials from the project site by one of three haul routes and do not result in any changes related to the future residences that are permitted on the site under the already approved La Strada development plan. Future structures on the project site would be constructed per the previously adopted conditions of approval. The modified grading permit does not result in any changes that would necessitate changes to the Final MND conclusions. This conclusion applies to all three haul routes. Finding: Because prescribed conditions of approval related to the incorporation of design features to reduce risk of wildland fire impacts would be implemented, the proposed activity would neither negate nor substantially exacerbate the significance of impacts related to wildland fires. The impact would remain less than significant. Thus, the previously identified wildland fire impacts would not be made substantially more severe as a result of the proposed activity and there are no changes or new information that would require the preparation of a Supplemental or Subsequent MND. 9. Hydrology and Water Quality- Would the proposed activity: a) Violate any water quality standards or waste discharge requirements? MND No. 2005-I Conclusion: Less than Significant Impact with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area noted that with incorporation of mitigation measures identified in the geology section of the MND (related to implementation of SWPPP best management practices), impacts related to water quality standards would be reduced to below a level of significance (page 39). Discussion of Modified Grading Permit. Modifications to the grading permit would not change grading activities in a manner that would result in a change in the Final MND conclusions regarding water quality standards and waste discharge requirements. The proposed activity would still be required to implement best management practices identified in the SWPPP. Additionally, mitigation measures identified for air quality, which require dampening of soils to minimize loss of soil by wind-driven forces would still be required to be implemented under the La Strada project and would further help to minimize soil loss. Thus, no change in impact is identified. This conclusion would remain the same for each of the haul routes. Finding: Because prescribed mitigation measures from the Final MND (III-b.l through III.b-16 for air quality) would be implemented, the proposed activity would neither negate nor substantially exacerbate the significance of water quality impacts. The impact would remain mitigated to below a level of significance. Thus, the previously identified water quality impacts would not be made substantially more severe as a result of the proposed activity and there are no changes or new information that would require the preparation of a Supplemental or Subsequent MND. b) Substantially deplete groundwater supplies or interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level (e.g., the production rate of preexisting nearby wells would drop to a level that would not support existing land uses or planned uses for which permits have been granted)? La Strada Modified Grading Permit 40 City of Lake Elsinore Canyon Creek Specific Plan February 2010 CC February 09, 2010 Item No. 10 Page 57 of 85 Initial Stud MND No. 2005-1 Conclusion: Less than Significant Impact The Final MND prepared for the La Strada Planning Area noted that the project site is underlain by bedrock and would not be considered a groundwater recharge area. The analysis concluded that the project would have a less than significant impact with regard to depletion of groundwater or groundwater recharge (page 39). Discussion of Modified Grading Permit. The modified grading plan would not result in a change with regard to groundwater recharge or use. As noted in the Final MND, underlying bedrock precludes the site from being an area for groundwater recharge. Modifications to the grading plan do not change that conclusion. Modifications to the grading plan do not result in an increase in groundwater use. Therefore, previous conclusions in the Final MND are still accurate. This conclusion applies to all three haul routes. Finding: Because the proposed activity would not alter existing conditions which preclude an impact related to the depletion of groundwater supplies, there are no new impacts identified for this issue area. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. c) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, in a manner that would result in substantial erosion or siltation on- or off-site? MND No. 2005-1 Conclusion: Less than Significant Impact. The Final MND prepared for the La Strada Planning Area noted that the project would alter a small portion of a stream. However, the proposed drainage design would capture storm runoff and convey flows through a detention basin and then into existing drainage facilities. Impacts were determined to be less than significant (page 39). Discussion of Modified Grading Permit. Modifications to the grading plan address the export of excess soil material through one of three haul routes. Grading on the project site would still be conducted in a manner to ensure that the existing drainage pattern of the site would not be substantially altered. Additionally, hauling under Routes I and 2 would occur on existing disturbed areas and, therefore, would not result in impacts to existing drainage patterns. Haul Route 3 would require the construction of a new road through undisturbed areas. Construction of this road was contemplated in the La Strada Final MND but not fully analyzed because the final alignment was unknown. As stated in the La Strada Final MND, construction of Haul Route 3 would require additional CEQA analysis to fully address all potential construction impacts. Finding: Under Haul Routes I and 2, the proposed activity would not substantially alter drainage patterns and there are no new impacts identified for this issue area. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. Haul Route 3 would require the construction of a new road through undisturbed areas. Construction of this road was contemplated in the La Strada Final MND but not fully analyzed because the final alignment was unknown. As stated in the La Strada Final WD, construction of Haul Route 3 would require additional CEQA analysis to fully address all potential construction impacts. A conclusion regarding the appropriateness of an MND Addendum for purposes of Haul Route 3 cannot be made. La Strada Modified Grading Permit Canyon Creek Specific Plan 41 City of Lake Elsinore February 2010 CC February 09, 2010 Item No. 10 Page 58 of 85 Initial d) Substantially alter the existing drainage pattern of the site or area, including through tl:e alteration of tile course of a stream or river, or substantially increase the rate or amount of surface runoff in a manner that would result in flooding on- or off-site? MND No. 2005-I Conclusion: Less than Significant Impact with Mitigation Incorporated The Final MND prepared for the La Strada Planning Area concluded that the project would not substantially alter the existing drainage patterns of the site. The site Hydrology Study prepared for the project indicated that due to the increased runoff associated with development, an onsite detention basin is needed to meet the 10 year 24 hour hydrology calculations (page 39). Implementation of a mitigation measure (VIIIA-1), that requires the installation of a detention basin, would ensure that the impact is less than significant. Discussion of Modified Grading Permit: Modifications to the grading plan address the export of excess soil material through one of three haul routes. Grading on the project site would still be conducted in a manner to ensure that the existing drainage pattern of the site would not be substantially altered to increase the rate or amount of surface runoff in a manner that would result in flooding on- or off-site. Additionally, hauling under Routes 1 and 2 would occur on existing disturbed areas and therefore would not result in impacts to existing drainage patterns. Haul Route 3 would require the construction of a new road through undisturbed areas. Construction of this road was contemplated in the La Strada Final MND but not fully analyzed because the final alignment was unknown. As stated in the La Strada Final MND, construction of Haul Route 3 would require additional CEQA analysis to fully address all potential construction impacts. Finding: Under Haul Routes 1 and 2, the proposed activity would not substantially alter drainage patterns and there are no new impacts identified for this issue area. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. Haul Route 3 would require the construction of a new road through undisturbed areas. Construction of this road was contemplated in the La Strada Final MND but not fully analyzed because the final alignment was unknown. As stated in the La Strada Final MND, construction of Haul Route 3 would require additional CEQA analysis to fully address all potential construction impacts. A conclusion regarding the appropriateness of an MND Addendum for purposes of Haul Route 3 cannot be made. e) Create or contribute runoff water that would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff? MND No. 2005-1 Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that the project with incorporation of project design features as a condition of project approval, would not contribute or create runoff water that would exceed the capacity of existing or planned stormwater drainage systems. Design features referenced include implementation of the best management practices identified in the SWPPP (page 40). Discussion of Modified Grading Permit: Modifications to the grading plan address the export of excess soil material through one of three haul routes. Grading on the project site would still be conducted in a manner to ensure that the proposed activity would not create or contribute runoff water that would exceed the capacity of existing or planned stormwater drainage systems. Future La Strada Modified Grading Permit 42 City of Lake Elsinore Canyon Creek Specific Plan February 2010 CC February 09, 2010 Item No. 10 Page 59 of 85 Initial development on the project site, which was approved as part of the original Canyon Hills Specific Plan, as modified by MND 2005-1, will be developed in a manner consistent with the drainage and stormwater master plan for the site. Therefore, no new impacts related to stormwater are identified for the proposed activity. This conclusion is applicable to all three haul routes. Finding: Because prescribed project design features included in the original conditions of approval for the La Strada MND would be implemented, the proposed activity would neither negate nor substantially exacerbate the significance of hydrology and water quality impacts. The impact would remain mitigated to below a level of significance. Thus, the previously identified hydrology and water quality impacts would not be made substantially more severe as a result of the proposed activity and there are no changes or new information that would require the preparation of a Supplemental or Subsequent MND. J) Otherwise substantially degrade water quality? MAD No. 2005-1 Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that with incorporation of project design features as a condition of project approval, the project would not substantially degrade water quality. Design features referenced include implementation of the best management practices identified in the SWPPP (page 40). Discussion ofModifted Grading Permit. Modifications to the grading plan address the export of excess soil material through one of three haul routes. Grading on the project site would still be conducted in a manner to ensure that the proposed activity would not create or contribute runoff water that would exceed the capacity of existing or planned stormwater drainage systems. Future development on the project site, which was approved as part of the original Canyon Hills Specific Plan, as modified by MND 2005-1, will be developed in a manner consistent with the drainage and stormwater master plan for the site. Mitigation measures already in place for the La Strada project include a variety of mitigation measures related to dust control and suppression (mitigation measures III.b-1 through III.b-16). Therefore, no new impacts related to stormwater are identified for the proposed activity. This conclusion is applicable to all three haul routes. Finding: Because prescribed mitigation measures (III.b-1 through III.b-16) from the Final MND would be implemented, the proposed activity would neither negate nor substantially exacerbate the significance of water quality impacts. The impact would remain mitigated to below a level of significance. Thus, the previously identified water quality impacts would not be made substantially more severe as a result of the proposed activity and there are no changes or new information that would require the preparation of a Supplemental or Subsequent MND. La Strada Modified Grading Permit Canyon Creek Specific Plan 43 City of Lake Elsinore February 2010 CC February 09, 2010 Item No. 10 Page 60 of 85 Initial g) Place housing within a 100 year food hazard area as mapped on a Federal Flood Hazard Boundary or Flood Insurance Rate Map or other food hazard delineation? MND No. 2005-1 Conclusion: Less than Significant. The Final MND prepared for the La Strada Planning Area concluded that the site is not in an area designated as a 100-year floodplain (page 40). Discussion of Modified Grading Permit. The project site remains outside of a designated 100-year floodplain, thus impacts are still less than significant. This conclusion is applicable to all three haul routes. Findings: Because the proposed activity site is not within a designated 100-year floodplain, there are no new impacts identified for this issue area. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. h) Place within a 100 year food hazard area structures that would impede or redirect flood flows. MAD No. 2005-1 Conclusion: Less than Significant. The Final MND prepared for the La Strada Planning Area concluded that the site is not in an area designated as a 100-year floodplain (page 40). Discussion of Modified Grading Permit. The project site remains outside of a designated 100- year floodplain, thus impacts are still less than significant. This conclusion is applicable to all three haul routes. Findings: Because the proposed activity site is not within a designated 100-year floodplain, there are no new impacts identified for this issue area. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. i) Expose people or structures to a significant risk of loss, injury, or death involving flooding, including flooding as a result of the failure of a levee or dam? MND No. 2005-1 Conclusion: Less than Significant. The Final MND prepared for the La Strada Planning Area concluded that there are no upstream dams or levees which could pose a flooding risk to the project site. Additionally, the site is outside of a 100-year floodplain. Thus impacts were identified as less than significant (page 40). Discussion of Modified Grading Permit. The project site remains outside of a designated 100- year floodplain and is not located downstream of any dams or levees; thus impacts would continue to be less than significant. This conclusion is applicable to all three haul routes. Findings: Because the proposed activity site is not downstream of any dams or levees, nor is located within a designated 100-year floodplain, there are no new impacts identified for this issue area. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. La Strada Modified Grading Permit 44 City of Lake Elsinore Canyon Creek Specific Plan February 2010 CC February 09, 2010 Item No. 10 Page 61 of 85 Initial Study j) Expose people or structures to inundation by seiche, tsunami, or mudflow? MAD No. 2005-1 Conclusion: No Impact. The Final MND prepared for the La Strada Planning Area concluded that the project site is not subject to mudflows, seiches or tsunamis due to project's elevation and distance from bodies of water (page 40). Discussion ofModifred Grading Permit. The project site remains at an elevation and distance away from water bodies that impacts would not occur related to inundation by seiche, tsunami or mudflow. Therefore, no impact is identified. This conclusion is applicable to all three haul routes. Findings: Because the proposed activity site would not be subject to inundation by seiche, tsunami, or mudflow, there are no new impacts identified for this issue area. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. 10. Land Use and Planning - Would the proposed activity: a) Physically divide an established community? MND No. 2005-1 Conclusion: Less than Significant The Final MND prepared for the La Strada Planning Area concluded that the project would not result in the division of an established community and that impacts would be less than significant (page 40). Discussion ofModifted Grading Permit. The grading plan modifications address the routing of haul material that needs to be exported from the site. This activity would not result in the division of an established community. Therefore, impacts would be less than significant. This conclusion would apply to all three haul routes. Findings: Because the proposed activity site would not result in the division of an established community, there are no new impacts identified for this issue area. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. b) Conflict with any applicable land use plan, policy, or regulation of an agency with jurisdiction over the project (including, but not limited to the general plan, specific plan, local coastal program, or zoning ordinance) adopted for the purpose of avoiding or mitigating an environmental effect? MAD No. 2005-1 Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that with approval of the Specific Plan Amendment proposed at that time, the project would reduce conflicts with applicable land use plans (page 41). Discussion of Modified Grading Permit. The grading plan modifications address the routing of haul material that needs to be exported from the site. This activity would not result in the inconsistency with adopted land use plans. Therefore, impacts would be less than significant. La Strada Modified Grading Permit Canyon Creek Specific Plan 45 City of Lake Elsinore February 2010 CC February 09, 2010 Item No. 10 Page 62 of 85 Initial With regard to land use compatibility, depending on the haul route that is selected (Haul Routed and 2) trucks may pass through residential areas. Construction activities are governed by the City's Noise Ordinance (Section 17.78.080), which limits the hours and days of the week that construction activity can occur. Hauling activities would fall under that as well. Also, it is estimated that, on average, 10 haul trucks would remove material per day, which equates to a little more than one truck per hour. Depending on demand, that number of trucks could increase to 40 trucks per day. This would only happen once per week. Under that scenario, 8 hour work day equates to an average of 5 trucks per hour or one truck every 12 minutes. Again, this would be no more than once a week. Under typical scenarios, trucks would generally be at the rate of one per hour. Under either scenario, this would not be characterized as an intensity that would cause a land use compatibility impact due to the short-term nature of construction. This conclusion applies to Haul Routes l and 2. Haul Route 3 would not involve trucks moving through residential areas, as it proposes taking the export material across the project site to I-15 via New La Strada, Camino del Norte and the Main Street ramps. Under all hauling routes, impacts would be less than significant. Findings: Because the proposed activity site would not conflict with an adopted land use plan or ordinance, and the Specific Plan Amendment has already been adopted, there are no new impacts identified for this issue area. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. c) Conflict with any applicable habitat conservation plan or natural community conservation plan? MND No. 2005-I Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that project was designed to comply with the intent of the MSHCP. The analysis noted that the access road to La Strada was conceptual at the time, but would occur within the open space. The analysis goes on to note that the road was identified within the MSHCP. The analysis also noted that when the final alignment for La Strada (Haul Route 3) is identified, additional CEQA analysis would be conducted (page 41). Discussion of Modified Grading Permit: Because the proposed grading area is consistent with the grading area analyzed in the Final MND, no new significant impacts related to a conflict with the MSHCP are identified. Mitigation identified in the Final MND would still be applicable. Additionally, Haul Routes 1 and 2 would occur on existing disturbed areas and, therefore, would not result in biological impacts. Hauling under Scenario 3 would require the construction of a new road through undisturbed areas dedicated for conservation in the MSHCP. However, the MSHCP considered construction of La Strada Road, but does not identify a final alignment. Construction of this road was contemplated in the La Strada Final MND but not fully analyzed because the final alignment was unknown. As stated in the La Strada Final MND, construction of Haul Route 3 would require additional CEQA analysis to fully address all potential construction impacts and consistency with the MSHCP. Finding: Because prescribed mitigation measures from the Final MND (III.b-1 through III.b-16) have already been implemented, the proposed activity would neither negate nor substantially exacerbate the significance of impacts to the MSHCP. The impact would remain mitigated to below a level of significance. Thus, the previously identified impact associated with compliance La Strada Modified Grading Permit 46 City of Lake Elsinore Canyon Creek Specific Plan February 2010 CC February 09, 2010 Item No. 10 Page 63 of 85 Initial to the MSHCP would not be made substantially more severe as a result of the proposed activity and there are no changes or new information that would require the preparation of a Supplemental or Subsequent MND. 11. Mineral Resources -Would the proposed activity: a) Result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the State? MAD No. 2005-1 Conclusion: No Impact. The Final MND prepared for the La Strada Planning Area concluded that the project site does not contain any mineral resources that would be of value to the State or region. Therefore, no impact was identified for this issue area (page 41). Discussion of Modified Grading Permit. The project site is not known to support unique mineral resource, therefore, the modified grading plan would not result in any impacts. This conclusion applies to all three haul routes. Finding: Because the proposed activity site does not contain any mineral resources that would be of value to the State or region, there are no new impacts identified for the loss of mineral resources. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. b) Result in the loss of availability of a locally important mineral resource recovery site delineated on a local general plan, specific plan or other land use plan? MND No. 2005-1 Conclusion: No Impact. The Final MND prepared for the La Strada Planning Area concluded that the project site is not designated as a locally-important mineral resource recovery site by any plan. Therefore, no impact was identified for this issue area (page 41). Discussion of Modified Grading Permit. The project site is not known to support any unique locally important mineral resource recovery site delineated on a local general plan, specific plan or other land use plan, therefore, the modified grading plan would not result in any impacts. This conclusion applies to all three haul routes. Finding. Because the proposed activity site is not identified as a locally important mineral resource recovery site, there are no new impacts identified for this issue area. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. 12. Noise - Would the proposed activity: a) Result in the exposure of persons to or generation of noise levels in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? MAD No. 2005-1 Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that the project would result in the exposure of persons to or generate a level of noise in excess of standards established by the City during both the construction and operation phase of the project (page 42). Mitigation measures La Strada Modified Grading Permit 47 City of Lake Elsinore Canyon Creek Specific Plan February 2010 CC February 09, 2010 Item No. 10 Page 64 of 85 Initial Study were identified (XI.a-1 through XI.a-8) to reduce the impacts to below a level of significance. Mitigation measures Xl.a-1 through XI.a-4 address potential impacts related to future vehicular noise from La Strada impacting the residential uses on the site. Mitigation included construction of a sound wall for select lots facing La Strada, providing a "closed window" condition for select homes, providing windows that meet Sound Transmission Class (STC) rating of 26 or higher for select homes and also providing weather stripping solid core exterior doors and exterior wall/roof assemblies free of cut outs or openings for homes facing La Strada. Mitigation measures XI.1-1.5 through XI. 1-8 address construction related noise and required locating construction and stockpiling areas away from existing residential uses as far as practicable, limiting the days and time of construction activities, establishing a noise complaint program and using noise control equipment on construction equipment. With these mitigation measures, operational and construction impacts were determined to be less than significant (page 43). Discussion of Modified Grading Permit: The proposed modifications to the grading permit would have no impact on operational noise. Noise associated with the grading for this project was already addressed in the Final MND prepared for the project and was determined to be less than significant with incorporation of mitigation. That mitigation would continue to apply. The proposed modified grading permit includes a processing component to the grading, as well as export via one of three haul routes. The processing and hauling would be required to comply with the City's Noise Ordinance (Section 17.78.080.F.1), which addresses short-term noise impacts and construction scheduling. The proposed activity would be required to adhere to these requirements, as well as the previous noise mitigation indentified in MND 2005-1. Additionally, the proposed processing area is buffered approximately 250 feet from the closest sensitive residential receptor. Given the large attenuation of noise with distance, as well as the timing limits on construction activities, the processing would not result in an impact to adjacent sensitive receptors. With regard to noise associated with haul trucks, depending on the haul route that is selected (Haul Routes 1 and 2) trucks may pass through residential areas. As noted, construction activities are governed by the City's Noise Ordinance, which limits the hours and days of the week that construction activity can occur. Hauling activities would fall under that as well. Also, it is estimated that, on average, 10 haul trucks would remove material per day, which equates to a little more than one truck per hour. In some instances, depending on demand, that number of trucks could increase to 40 trucks per day. Assuming an 8-hour work day, that equates to an average of 5 trucks per hour or one truck every 12 minutes. This would not be characterized as an intensity that would cause a substantial increase in the noise environment. This conclusion applies to Hauling Routes 1 and 2. Hauling Route 3 would not involve trucks moving through residential areas, as it proposes taking the export material across the project site to I-15 via New La Strada, Camino del Norte and the Main Street ramps. Under all haul routes, impacts would be less than significant with mitigation already prescribed in the Final MD. Finding: Because prescribed mitigation measures from the Final MND (XI.1-5 through XI.1-8) would be implemented, the proposed activity would neither negate nor substantially exacerbate the significance of noise impacts. The impact would remain mitigated to below a level of significance. Thus, the previously identified noise impacts would not be made substantially more severe as a result of the proposed activity and there are no changes or new information that would require the preparation of a Supplemental or Subsequent MND. La Strada Modified Grading Permit Canyon Creek Specific Plan 48 City of Lake Elsinore February 2010 CC February 09, 2010 Item No. 10 Page 65 of 85 Initial Study b) Expose persons to or generation of excessive groundborne vibration or groundborne noise levels? MND No. 2005-1 Conclusion: Less than Significant. The Final MND prepared for the La Strada Planning Area concluded that the project may expose some existing residential uses in the east to vibration or groundborne noise during construction, but that no high-nuisance activities such as blasting or pile driving would occur (page 43). These disturbances were determined to be temporary and less than significant. Discussion of Modified Grading Permit: The modified grading plan would not result in any change in activity which would result in an increase in excessive groundborne vibrations or noise above the level previously analyzed. No pile driving or blasting would be required. Therefore, no new impacts are identified. This conclusion applies to all three haul routes. Finding: Because the proposed activity would not result in an increase in excessive groundborne vibrations, the proposed activity would neither negate nor substantially exacerbate the significance of vibration impacts. The impact would remain less than significant. Thus, the previously identified vibration impacts would not be made substantially more severe as a result of the proposed activity and there are no changes or new information that would require the preparation of a Supplemental or Subsequent MND. c) Result in a substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project? MND No. 2005-1 Conclusion: Less than Significant. The Final MND prepared for the La Strada Planning Area concluded that the project would result in permanent increases in the ambient noise environment, but those increases were below a level of significance (page 43). Discussion of Modified Grading Permit: The modified grading permit does not result in a long- term change in noise conditions compared to what was analyzed in Final MND 2005-1. The modified grading plan changes the distribution of short term construction noise due to the potential for routing of haul trucks through residential neighborhoods. This is addressed in 1 l.a. In conclusion, the modified grading permit does not result in any new substantial permanent increase in ambient noise levels in the project area that were not considered as part of the Final MND. A less than significant impact is identified for this issue area. This conclusion applies to all three haul routes. Finding: Because the proposed modifications to the grading plan have no effect on land use and intensity, the proposed activity would not result in a permanent increase in ambient noise levels beyond what was already analyzed in the Final MND. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. d) Result in a substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels existing without the project? La Strada Modified Grading Permit Canyon Creek Specific Plan 49 City of Lake Elsinore February 2010 CC February 09, 2010 Item No. 10 Page 66 of 85 Initial MND No. 2005-1 Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that the project would result in a temporary or periodic increase ambient noise levels due to short-term construction noise. Mitigation measures XI.1-5 through XI.1-8 address construction related noise and required locating construction and stockpiling areas way from existing residential as far as practicable, limiting the day and time of construction activities, establishing a noise complaint program, and using noise control equipment on construction equipment. With these mitigation measures, impacts were determined to be less than significant (page 43). Discussion of Modified Grading permit: Noise associated with grading for the proposed activity has already been addressed in the Final MND prepared for the La Strada project. The proposed modified grading permit includes a processing component to the grading, as well as export via one of three routes. The processing and hauling would be required to comply with the City's Noise Ordinance (Section 17.78.080.F.1), which addresses short-term noise impacts and construction scheduling.

In some instances, depending on demand, that number of trucks could increase to 40 trucks per day. Assuming an 8 hour work day, that equates to an average of 5 trucks per hour or one truck every 12 minutes. This would not be characterized as an intensity that would cause a substantial increase in the noise environment. This conclusion applies to Haul Routes 1 and 2. Haul Route 3 would not involve trucks moving through residential areas, as it proposes taking the export material across the project site to I-15 via new La Strada, Camino del Norte and the Main Street ramps. Under all hauling routes, impacts would be less than significant. Finding: Because prescribed mitigation measures from the Final MND (XI. 1-5 through XI.1-8) would be implemented, the proposed activity would neither negate nor substantially exacerbate the significance of short-term noise impacts. The impact would remain mitigated to below a level of significance. Thus, the previously identified noise impacts would not be made substantially more severe as a result of the proposed activity and there are no changes or new information that would require the preparation of a Supplemental or Subsequent MND. e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? La Strada Modified Grading Permit Canyon Creek Specific Plan 50 City of Lake Elsinore February 2010 CC February 09, 2010 Item No. 10 Page 67 of 85 Initial Stud MAD No. 2005-1 Conclusion: No Impact. The Final MND prepared for the La Strada Planning Area concluded that the project site is not located in an airport land use plan or within two miles of a public or private airport. Therefore, no impact was identified for this issue area (page 43). Discussion of Modified Grading Permit: The existing conditions remain the same with regard to the project's location within an airport land use plan or adjacency to an airstrip. Therefore, no impact is identified for this issue area. This conclusion applies to all three haul routes. Finding. Because the proposed activity site is not located within an airport land use plan or within two miles of an airport, there are no new impacts identified for this issue area. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. J9 For a project within the vicinity of a private airstrip, would the project expose people residing or working in the project area to excessive noise levels? MND No. 2005-1 Conclusion: No Impact. The Final MND prepared for the La Strada Planning Area concluded that the project site is not located within two miles of a private airport. Therefore, no impact was identified for this issue area (page 43). Discussion ofModifted Grading Permit. The existing conditions remain the same with regard to the proposed activity's location not being near a private airstrip. Therefore, no impact is identified for this issue area. This conclusion applies to all three haul routes. Finding: Because the proposed activity site is not located within the vicinity an airstrip, there are no new impacts identified for this issue area. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. 13. Population and Housing - Would the proposed activity: a) Induce substantial population growth in an area, either directly (e.g., by proposing new homes and businesses) or indirectly (e.g., through extension of roads or other infrastructure)? MAD No. 2005-1 Conclusion: Less than Significant. The Final MND prepared for the La Strada Planning Area concluded that the project would not induce substantial population growth either directly or indirectly. Impacts were determined to be less than significant (page 44). Discussion ofModifted Grading Permit: The modified grading plan addresses grading and export of excess soil material. These changes do not result in any changes in density or development of infrastructure that would result in substantial population growth. Under Haul Route 3, a road would be constructed to connect the project site with I-15 via New La Strada, Camino del Norte and the Main Street ramps. This road was contemplated in the La Strada MND and was not identified as being growth inducing. Further, La Strada is identified as a secondary road in the City's proposed General Plan Update Circulation Element. Therefore, impacts are still determined to be less than significant for hauling under Route 3. For Haul Routes. l and 2, no new roads would be developed and impacts would also be less than significant. La Strada Modified Grading Permit 51 City of Lake Elsinore Canyon Creek Specific Plan February 2010 CC February 09, 2010 Item No. 10 Page 68 of 85 Initial Finding: Because the proposed activity does not propose changes in density or development of infrastructure that would result in substantial population growth, there are no new impacts identified for this issue area. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. b) Displace substantial numbers of existing housing, necessitating the construction of replacement housing elsewhere? MAD No. 2005-1 Conclusion: No Impact. The Final MND prepared for the La Strada Planning Area concluded that the project would not have an impact related to displacement of housing, as the project site is vacant (page 44). Discussion of Modified Grading Permit: The project site is currently vacant. Therefore, the proposed modified grading plan would not result in the displacement of housing. Therefore, no impact is identified for this issue area. This conclusion would apply to all three haul routes. Finding: Because the proposed activity site is vacant and would not displace existing housing, there are no new impacts identified for this issue area. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. c) Displace substantial numbers of people, necessitating the construction of replacement housing elsewhere? MND No. 2005-1 Conclusion: No Impact. The Final MND prepared for the La Strada Planning Area concluded that the project would not have an impact related to displacement of people since the project site is vacant (page 44). Discussion of Modified Grading Permit: The project site is currently vacant. Therefore, the proposed modified grading plan would not result in the displacement of people. Therefore, no impact is identified for this issue area. This conclusion would apply to all three haul routes. Finding: Because the proposed activity site is vacant and would not displace existing housing or people, there are no new impacts identified for this issue area. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. 14. Public Services - Would the proposed activity: a) Result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which would cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for any of the following public services? i) Fire protection? La Strada Modified Grading Permit Canyon Creek Specific Plan 52 City of Lake Elsinore February 2010 CC February 09, 2010 Item No. 10 Page 69 of 85 Initial MAD No. 2005-1 Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that the project would reduce impacts to fire protection service to below a level of significance through the payment of Development Impact Fees, a portion of which goes towards funding facilities and staff for fire protection (page 44). Discussion of Modified Grading Permit: Implementation of the modified grading plan would not affect the proposed uses or density already approved in the Canyon Lake Specific Plan Amendment. Therefore, the proposed activity would not result in an increase in demand for fire protection services at the project site. A less than significant impact is identified for this issue area. This conclusion applies to all three haul routes. Finding. Because the proposed activity does not propose changes to the land use plan and density of the site, no additional impacts to fire protection would occur. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. ii) Police protection? MND No. 2005-1 Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that the project would reduce impacts to police protection service to below a level of significance through the implementation of standard conditions of approval (page 45). Discussion of Modified Grading Permit. Implementation of the modified grading plan would not affect the proposed uses or density already approved in the Canyon Lake Specific Plan Amendment. Therefore, the proposed activity would not result in an increase in demand for police services. A less than significant impact is identified for this issue area. This conclusion applies to all three haul routes. Finding: Because the proposed activity does not propose changes to the land use plan and density of the site, no additional impacts to fire protection would occur. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. iii) Schools? MAD No. 2005-1 Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that development within the planning area would increase student enrollment at schools within the Lake Elsinore Unified School District. To offset any potential cumulative impact on the school district's education system, the La Strada project is required to pay appropriate school fees in accordance with SB 50 (page 45). This would reduce impacts to school services below a level of significance through the implementation of standard conditions of approval. Discussion of Modified Grading Permit: Implementation of the modified grading plan would not affect the proposed uses or density already approved in the Final MND for the La Strada project. Therefore, the proposed activity would not result in an increase in demand for La Strada Modified Grading Permit 53 City of Lake Elsinore Canyon Creek Specific Plan February 2010 CC February 09, 2010 Item No. 10 Page 70 of 85 Initial schools. A less than significant impact is identified for this issue area. This conclusion applies to all three haul routes. Finding. Because the proposed activity does not propose changes to the land use plan and density of the site, no additional impacts to schools would occur. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. iv) Parks? MND No. 2005-1 Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that the proposed activity would reduce impacts to parks to below a level of significance through the payment of park fees per proposed dwelling unit (page 45). These park fees would go to acquire and maintain additional park space within the City. Discussion of Modified Grading Permit. Implementation of the modified grading plan would not affect the proposed uses or density already approved in the Final MND for the proposed activity site. Therefore, the proposed activity would not result in an increase in demand for parks. A less than significant impact is identified for this issue area. This conclusion applies to all three haul routes. Finding: Because the proposed activity does not propose changes to the land use plan and density of the site, no additional impacts to parks would occur. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. v) Other public facilities? MAD No. 2005-1 Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that the project would reduce impacts to other public facilities through the payment of appropriate library and developer fees (page 45). Discussion of Modified Grading Permit: Implementation of the modified grading plan would not affect the proposed uses or density already approved in the Final MND for the La Strada project. Therefore, the proposed activity would not result in an increase in demand for library or other public facilities. A less than significant impact is identified for this issue area. This conclusion applies to all three haul routes. Finding: Because the proposed activity does not propose changes to the land use plan and density of the site, no additional impacts to parks would occur. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. La Strada Modified Grading Permit Canyon Creek Specific Plan 54 City of Lake Elsinore February 2010 CC February 09, 2010 Item No. 10 Page 71 of 85 Initial 15. Recreation - Would the proposed activity: a) Increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? MAD No. 2005-1 Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that the project would reduce recreation impacts through the payment of park fees per the Quimby Act (page 45). These park fees would be applied toward requiring and maintaining additional park space within the City and reduce the potential impact to recreation services and facilities to below a level of significance. Discussion of Modified Grading Permit: Implementation of the modified grading plan would not affect the proposed uses or density already approved in the Final MND for the La Strada project. Therefore, the proposed activity would not result in an increase in the use of recreational facilities. A less than significant impact is identified for this issue area. This conclusion applies to all three haul routes. Finding. Because the proposed activity does not propose changes to the land use plan and density of the site, no additional impacts to recreational facilities would occur. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. b) Provide recreational facilities or require the construction or expansion of recreational facilities that might have an adverse physical effect on the environment? MND No. 2005-1 Conclusion: Less than Significant. The Final MND prepared for the La Strada Planning Area concluded that the project would not have any additional environmental impacts associated with recreational amenity development beyond those already considered in the Final MND. Impacts were determined to be less than significant (page 46). Discussion of Modified Grading Permit: Implementation of the modified grading plan would not affect the proposed uses or density already approved in the Final MND for the La Strada project. Therefore, the proposed activity would not result in an increase in demand for recreational facilities. A less than significant impact is identified for this issue area. This conclusion applies to all three haul routes. Finding: Because the proposed activity does not propose changes to the land use plan and density of the site, no additional impacts to recreational facilities would occur. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. 16. Transportation/Traffic - Would the proposed activity: a) Cause an increase in traffic that is substantial in relation to the existing traffic load and capacity of the street system (i.e., result in a substantial increase in either the number of vehicle trips, the volume to capacity ratio on roads, or congestion at intersections)? La Strada Modified Grading Permit 55 City of Lake Elsinore Canyon Creek Specific Plan February 2010 CC February 09, 2010 Item No. 10 Page 72 of 85 Initial Study MND No. 2005-I Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that the project would cause an increase in traffic which would be substantial in relation to the existing traffic load. However, implementation of mitigation measures (XV-1 through XV-10) reduced the impact to less than significant (page 48). Mitigation measures XV-1 through XV-10 call for specific roadway and intersection enhancements to increase capacity and improve overall traffic flow. Discussion of Modified Grading Permit: The modified grading permit would allow for the hauling of soil export material. On average, 10 haul trucks would remove material per day, which equates to a little more than one truck per hour. In some instances, depending on demand, that number of trucks could increase to 40 trucks per day. This may occur once a week. Assuming an 8 hour work day, that equates to an average of 5 trucks per hour or one truck every 12 minutes. This would not be characterized as an intensity that would cause a substantial increase in the traffic. This applies to all haul routes. Additionally, intersection capacity analysis conducted at Summerhill Road and Railroad Canyon for Haul Route 1 noted that operations would remain at LOS C, which is considered adequate (Appendix D). Finding: Because prescribed mitigation measures from the Final MND (XV-1 through XV-10) would be implemented, the proposed activity would neither negate nor substantially exacerbate the significance of impacts association with operational traffic. Regarding construction traffic, the addition of truck trips (Haul Routes 1, 2 or 3) would not impact the existing traffic load and capacity of the circulation network. The impact would remain mitigated to below a level of significance. Thus, the previously identified impact related to traffic would not be made substantially more severe as a result of the proposed activity and there are no changes or new information that would require the preparation of a Supplemental or Subsequent MND. b) Exceed, either individually or cumulatively, a level of service standard established by the county congestion management agency for designated roads or highways? MAY) No. 2005-I Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that the project would add to a cumulative traffic impact. However, implementation of mitigation measures (XV-1 through XV- 10) reduced the impact to less than significant (page 48). Mitigation measures XV-1 through XV- 10 call for specific roadway and intersection enhancements to increase capacity and improve overall traffic flow. Discussion of Modified Grading Permit: The modified grading permit would allow for the hauling of soil export material. On average, 10 haul trucks would remove material per day, which equates to a little more than one truck per hour. In some instances, depending on demand, that number of trucks could increase to 40 trucks per day (no more than once per week). Assuming an 8-hour work day, that equates to an average of five trucks per hour or one truck every 12 minutes. The addition of up to five trucks per hour (once a week) or one truck per hour (other days) would not be characterized as an exceedence, either individually or cumulatively, of a level of service standard established by the county congestion management agency for designated roads or highways. This conclusion applies to all three haul routes. Finding: Because prescribed mitigation measures from the Final MND (XV-1 through XV-10) would be implemented, the proposed activity would neither negate nor substantially exacerbate the significance of impacts association with operational traffic. Regarding construction traffic, La Strada Modified Grading Permit 56 City of Lake Elsinore Canyon Creek Specific Plan February 2010 CC February 09, 2010 Item No. 10 Page 73 of 85 Initial the addition of truck trips would not exceed the City's level of service standard of D. The impact would remain mitigated to below a level of significance. Thus, the previously identified impact related to traffic would not be made substantially more severe as a result of the proposed activity and there are no changes or new information that would require the preparation of a Supplemental or Subsequent MND. c) Result in a change in air traffic patterns, including either an increase in traffic levels or a change in location that results in substantial safety risks? MAD No. 2005-1 Conclusion: No Impact. The Final MND prepared for the La Strada Planning Area concluded that the project would have no impact related to air traffic patterns since the project is not located near an airport (page 48). Discussion of Modified Grading Permit: No airports are located in the vicinity of the project site. Additionally, the proposed activity, which is a modification to the grading plan, would not result in any changes to air traffic patterns. Thus no impact is identified. This conclusion applies to all three haul routes. Finding: Because the proposed activity is not located near an airport, nor would it impact air traffic patterns, no impact would occur related to air traffic patterns. Therefore, there are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. d) Substantially increase hazards due to a design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? MAD No. 2005-1 Conclusion: Less than Significant Impact. The Final MND prepared for the La Strada Planning Area concluded that the project would have no impact related to hazards due to a design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment (page 48). Discussion of Modified Grading Permit: The modified grading permit does not result in any changes to street design. Therefore, the impact would continue to be less than significant. This conclusion applies to all three haul routes. Finding: Because the proposed activity would not affect design features related to street design or incompatible uses, a less than significant impact would continue to occur related to hazardous design features. Therefore, there are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. e) Result in inadequate emergency access? MND No. 2005-I Conclusion: Less than Significant Impact. The Final MND prepared for the La Strada Planning Area concluded that the project would have a less than significant impact with regard to emergency access (page 48). Both the police and fire department reviewed the project and did not express any concerns regarding the project and emergency access. La Strada Modified Grading Permit Canyon Creek Specific Plan 57 City of Lake Elsinore February 2010 CC February 09, 2010 Item No. 10 Page 74 of 85 Initial Study Discussion of Modified Grading Permit. The proposed activity identifies three haul routes to remove excess soil material from the project site. There is existing access to the project site through an adjacent residential neighborhood. Three haul routes are considered. Haul Route 1 would take material from project site to I-15 via La Strada and Summerhill Drive. Haul Route 2 would move material would be taken to SR-74 via La Strada, Bella Vista, and an unimproved road and Greenwald Avenue. Haul Route 3 would remove material from the project site to I-15 via New La Strada, Camino del Norte and Main Street ramps. None of these haul routes would result in inadequate emergency access to either the project site or adjacent uses. Finding. Because the proposed activity would not result in inadequate emergency access, no new impacts related to this issue area would occur. Therefore, there are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. J) Result in inadequate parking capacity? MND No. 2005-1 Conclusion: Less than Significant Impact. The Final MND prepared for the La Strada Planning Area concluded that the project would provide adequate parking per the City's General Plan and Zoning Code and that impacts would be less than significant (page 49). Discussion of Modified Grading Permit. The proposed activity is a modification to the grading plan and would not result in any changes to the proposed parking. No parking restrictions would be implemented due to the proposed hauling, regardless of what hauling scenario was selected. Therefore, impacts remain less than significant. Finding: Because the proposed activity would not result in inadequate parking, no new impacts related to this issue area would occur. Therefore, there are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. g) Conflict with adopted policies, plans, or programs supporting alternative transportation (e.g., bus turnouts, bicycle racks)? MND No. 2005-1 Conclusion: Less than Significant Impact. The Final MND prepared for the La Strada Planning Area concluded that the project would not have any proposed activities or designs that would conflict with any existing policies related to alternative transportation (page 49). Discussion of Modified Grading Permit. The proposed activity is a modification to the grading plan and would not result in any changes to the alternative transportation. Thus impacts remain less than significant. This conclusion applies to all three haul routes. Finding. Because the proposed activity would not conflict with adopted policies regarding alternative transportation, no new impacts related to this issue area would occur. Therefore, there are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. La Strada Modified Grading Permit Canyon Creek Specific Plan 58 City of Lake Elsinore February 2010 CC February 09, 2010 Item No. 10 Page 75 of 85 Initial Stud 17. Utilities and Service Systems - Would the proposed activity: a) Exceed wastewater treatment requirements of the applicable Regional Water Quality Control Board? MAD No. 2005-1 Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that the project would mitigate any potential impacts related to wastewater treatment through implementation of a SWPPP and compliance with a project-specific Water Quality Management Plan (WQMP) (page 49). Discussion of Modified Grading Permit. Implementation of the modified grading plan would not affect the proposed uses or density already approved for the project site in the Final MND. Therefore, the proposed activity would not result in an increase in demand for wastewater treatment services above the level previously analyzed in the Final MND. A less than significant impact is identified for this issue area. This conclusion applies to all three haul routes. Finding: Because the proposed activity does not propose changes to the land use plan and density of the site, no additional demand for wastewater treatment requirements would occur. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MD. b) Require or result in the construction of new water or wastewater treatment facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? MND No. 2005-1 Conclusion: Less than Significant Impact. The Final MND prepared for the La Strada Planning Area concluded that the wastewater generated by the project would have adequate capacity to be served by existing EVMWD facilities. In addition, the project applicant would pay connection and operation fees which would also add to future plan capacity. Impacts were determined to be less than significant (page 49). Discussion of Modified Grading Permit: Implementation of the modified grading plan would not affect the proposed uses or density already approved in the Canyon Creek Specific Plan Amendment. Therefore, the project would not result in an increase in demand for water and wastewater services above the levels previously analyzed in the Final MND. A less than significant impact is identified for this issue area. This conclusion applies to all three haul routes. Finding: Because the proposed activity does not propose changes to the land use plan and density of the site, no additional demand for water and wastewater treatment requirements would result. There are no new impacts, changes, or new information associated with the proposed activity that would require the preparation of a Supplemental or Subsequent MND. c) Require or result in the construction of new stormwater drainage facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? La Strada Modified Grading Permit Canyon Creek Specific Plan 59 City of Lake Elsinore February 2010 CC February 09, 2010 Item No. 10 Page 76 of 85 Initial MND No. 2005-1 Conclusion: Less than Significant with Mitigation Incorporation. The Final MND prepared for the La Strada Planning Area concluded that the project would not have any potential impacts related to stormwater drainage facilities, as the project would install detention basins and maintain runoff in a manner that meets downstream design requirements. With implementation of the detention basin as part of the project design features, impacts were reduced to below a level of significance (page 49). Discussion of Modified Grading Permit: Implementation of the modified grading permit does not result in an increase in need for stormwater drainage facilities. Buildout of the project area would be consistent with the previously approved Tract Map that accompanied Final MND 2005-1 and would include adequate stormwater facilities as well as the detention basin. Modification of the grading permit does not modify the project plans with regard to stormwater management and detention. Therefore, no new impacts are identified. This conclusion applies to all three haul routes. Finding. No new impacts for this issue area are identified and there are no changes in information that would require preparation of an FIR or a Supplemental or Subsequent MND exist. d) Have sufficient water supplies available to serve the project from existing entitlements and resources, or are new or expanded entitlements needed? MND No. 2005-1 Conclusion: Less than Significant Impact. The Final MND prepared for the La Strada Planning Area concluded that the project needed to provide additional water storage to meet the anticipated water demand. A one million gallon water storage reservoir was installed as part of the La Strada plan. Additionally, EVMWD indicated that they have adequate water to supply the project. Therefore, impacts were determined to be less than significant (page 50). Discussion of Modified Grading Permit. The proposed activity is a modification to the grading plan and does not result in any changes to the need for water supply or storage. Therefore, the conclusions of Final MND 2005-1 remain adequate and no additional impacts are identified. This conclusion applies to all three haul routes. Finding. No new impacts for this issue area and no changes in information that would require preparation of an FIR or a Supplemental or Subsequent MND exist. e) Result in a determination by the wastewater treatment provider that serves or may serve the project that it has adequate capacity to serve the project's projected demand in addition to the provider's existing commitments? MND No. 2005-1 Conclusion: Less than Significant Impact. The Final MND prepared for the La Strada Planning Area concluded that adequate wastewater treatment capacity was available to not only serve the project, but also additional service needs from other projects in the EVMWD service area. Therefore, impacts were determined to be less than significant (page 50). La Strada Modified Grading Permit Canyon Creek Specific Plan 60 City of Lake Elsinore February 2010 CC February 09, 2010 Item No. 10 Page 77 of 85 Initial Discussion of Modified Grading Permit: The proposed activity is a modification to the grading plan and does not result in any changes in demand for wastewater treatment capacity. Therefore, the conclusions of Final MND 2005-1 remain adequate and no additional impacts are identified. This conclusion applies to all three haul routes. Finding: No new impacts for this issue area and no changes in information that would require preparation of an EIR or a Supplemental or Subsequent MND exist. f Be served by a landfill with sufficient permitted capacity to accommodate the project's solid waste disposal needs? MND No. 2005-I Conclusion: Less than Significant Impact. The Final MND prepared for the La Strada Planning Area concluded that project would not generate solid waste above the capacities identified in the General Plan. Additionally, the City participates in a mandatory source reduction and recycling program which diverts solid waste from the landfills. Thus, impacts were determined to be less than significant (page 50). Discussion of Modified Grading Permit: The proposed activity is a modification to the grading plan and does not result in any changes in demand for landfill capacity. Excess soil from the grading operations on the project site will be exported from the site to other construction projects, thus reducing the amount of material that would be directed to the landfill. Therefore, the conclusions of Final MD 2005-1 remain adequate and no additional impacts are identified. This conclusion applies to all three haul routes. Finding. No new impacts for this issue area and no changes in information that would require preparation of an EIR or a Supplemental or Subsequent MND exist. g) Comply with Federal, State, and local statutes and regulations related to solid waste? MAD No. 2005-I Conclusion: Less than Significant Impact. The Final MND prepared for the La Strada Planning Area concluded that project would not conflict with and Federal, State or local statues or regulations with regard to solid waste (page 50). Discussion ofModifted Grading Permit: The proposed activity is a modification to the grading plan and does not result in any project changes which would cause incompliance with Federal, State or local statutes. Therefore, the conclusions of Final MND 2005-1 remain adequate and no additional impacts are identified. This conclusion applies to all three haul routes. Finding: No new impacts for this issue area and no changes in information that would require preparation of an EIR a Supplemental or Subsequent MND exist. La Strada Modified Grading Permit Canyon Creek Specific Plan 61 City of Lake Elsinore February 2010 CC February 09, 2010 Item No. 10 Page 78 of 85 Initial 18. Mandatory Findings of Significance a) POTENTIAL TO DEGRADE: Does the proposed activity have the potential to degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal, or eliminate important examples of the major periods of California history or prehistory? MAD No. 2005-1 Conclusion: Less than Significant Impact. The Final MND prepared for the La Strada Planning Area concluded that project would be located in a sensitive habitat area and is located within the MSHCP planning area. The project proposed included a set aside of permanent open space, consistent with the requirements of the MSCHP. This set aside reduced the potential for the project to degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self- sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal, or eliminate important examples of the major periods of California history or prehistory to below a level of significance (page 51). Discussion of Modified Grading Permit. Modification of the grading plan does not result in any changes to the proposed habitat conservation that was identified in the Specific Plan. Haul Routes I and 2 would export the soil via existing roadways. Therefore, the proposed activity does not result in new impacts which change the conclusions of Final MND 2005-1. Haul Route 3 would construct a road to connect the project site to I-15 via New La Strada, Camino del Norte and the Main Street ramp, a portion of which will go through portion of the proposed open space areas; however, this roadway was contemplated in the MSCHP and would not be considered a significant impact. However, additional CEQA analysis would be required for Haul Route 3 to make these mandatory findings. Finding: For the proposed activity under Haul Routes 1 and 2, there are no changes or new information associated with this proposed activity that would require the preparation of an EIR or a Supplemental or Subsequent MND. For Haul Route 3, additional analysis would be required to make the findings. b) CUMULATIVE IMPACTS: Does the proposed activity have impacts that are individually limited, but cumulatively considerable? ("Cumulatively considerable" means that the incremental effects of a project are considerable when reviewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future project.) MAD No. 2005-1 Conclusion: The Final MND prepared for the La Strada project did not identify any cumulative impacts that cannot be mitigated to below a level of significance. Implementation of design features and mitigation measure identified for biological resources, air quality and traffic in the Final MND reduces all impact to below a level of significance (page 51). . Discussion of Modified Grading Permit: Implementation of the modified grading permit will not result in an increase in cumulative impacts above and beyond those identified in Final MND La Strada Modified Grading Permit 62 City of Lake Elsinore Canyon Creek Specific Plan February 2010 CC February 09, 2010 Item No. 10 Page 79 of 85 Initial 2005-1. The proposed activity will still be required to implement the design feature and mitigation measures for biological resources, air quality and traffic. This conclusion applies to all three haul routes. Finding: Therefore, there are no changes or new information associated with this proposed activity that would require the preparation of an EIR or a Supplemental or Subsequent MND c) ADVERSE IMPACTS ONHUMANS: Does the proposed activity have environmental effects on human beings, either directly or indirectly? MND No. 2005-1 Conclusion: The Final MND prepared for the La Strada project noted that several impacts which could cause a substantial adverse effect on human being either directly or indirectly were mitigate to below a level of significance (page 51). Discussion of Modified Grading Permit. Potential effects to humans could result if the proposed activity would have impacts related to public health/safety, air quality or hazards. Based upon the analysis presented in this initial study, the proposed activity will not result in any impacts above and beyond those identified in Final MND 2005-1. The proposed activity will adhere to the City's Noise Ordinance for construction activities. This will ensure elevated sound levels are not generated which would be a nuisance to sensitive receptors. The air quality modeling for the proposed activity did not identify an exceedance of any criteria pollutant thresholds. Additionally, the proposed activity would implement the mitigation measures related to air quality identified in Final MND 2005-1. In summary, the modified grading permit does not result in any impacts to human beings, either directly or indirectly, that were not already considered in Final MND 2005-1. This analysis applies to all three haul routes. Finding: Therefore, there are no changes or new information associated with this proposed activity that would require the preparation of an FIR or a Supplemental or Subsequent MND. 19.
