Project is required to construct ultimate improvements on Baker Street including but not limited to design and construction of Baker Street realignment, asphalt pavement construction, curb, gutter, sidewalk, driveway approach(s), streetlights, striping, striping removal, signage relocations, utility relocations, and ADA curb ramp constructions. 2. Project is required to construct ultimate improvements on Pierce Street including but not limited to design and construction of Pierce Street realignment, asphalt pavement construction, curb, gutter, sidewalk, driveway approach(s), streetlights, striping, striping removal, signage relocations, utility relocations, and ADA curb ramp constructions. 3. Ensure the following dedications are recorded on the final map or per separate instrument(s) at or prior to the final map recording: a. A dedication along Baker Street property frontage such that the full width is 68 feet. Baker Street is classified as a Collector Roadway in the General Plan Circulation Element with 68-feet full-width and 48-feet curb to curb width. b. A dedication along Pierce Street such that the full width is 60 feet. Pierce Street is classified as a Local Roadway in the General Plan Circulation Element with a 60-feet full width and a 40-feet curb to curb width. c. Dedication(s) of right-of-way necessary to realign Baker Street and Pierce Street for future alignment. 4. Project is required to provide adequate secondary access for proposed Parcels 2 and 3. 5. Ensure the Tentative Map is titled properly and show the flood lines at the northeasterly area of the map. 6. Please see attached redlined comments for preliminary drainage report. a. In General, there are some inconsistencies between the WQMP and hydrology report (i.e. hydrology report discusses MWS for Baker Street treatm ent and there is no treatment in the WQMP). Ensure both are reflective of the other. 7. Project WQMP will be required to treat the flows from the improved Baker Street and Pierce Street DMAs. 8. The project Preliminary W QMP Site Plan legend should show the WQMP facilities identified in a different color than the parking lot. 9. The project will be required to submit a Preliminary Soils Report/Geotechnical Study. Please provide a preliminary report in the formal submittal. a. Since the project proposes to use infiltration for some of its water quality facilities, infiltration testing will be required. Ensure all infiltration tests are performed in accordance with the Riverside County Flood Control Water Conservation District (RCFCWCD), Design Handbook for LID BMPs.

Project will need to provide a Hydraulic analysis section in the Drainage Report for the proposed storm drain lines. 11. An easement to the City of Lake Elsinore will be required for the proposed 36-inch storm drain lines. 12. The hillside grading proposed for the project will be required to follow Lake Elsinore Municipal Code 15.72. Conceptually, the grading plan exceeds the 30-foot vertical cut limit in various locations. 13. The conceptual grading plan includes general note information that does not detail the gradin g. Please review the design manual and include pertinent information such as area of disturbance, import, export, etc. 14. Ensure proper sight distances meet City standard for each driveway. Existing or placement of utilities, landscaping, and signage shall not obstruct sight distances. 15. Project will be required to complete a Traffic Scoping Agreement with the City Traffic Engineer for review and approval. Please use TIA Preparation Guide (http://www.lake- elsinore.org/home/showdocument?id=26703). a. If found required by the Traffic Scoping Agreement, a Traffic Impact Analysis will need to be submitted for review and approval. 16. All Overhead utilities (34.5 KV or lower) shall be ungrounded per LEMC 16.64. 17. It is recommended to coordinate with SCE early and often in the development process to review load forecasts and started advanced engineering study to determine the method and scope for providing service. 18. The project will be subject to pay Engineering assessed Development Impact Fees that includes but not limited to K-Rat, Area Drainage Fee, Transportation Uniform Mitigation Fee, and Traffic Infrastructure Fee. 19. Project is required to detain the incremental 10-year pre- and post-development difference. 20. Installation of streetlights along all constructed streets identified in the project will be required. Streetlight system shall be a LS-2B system. Location and pole specifications may be determined at design stage. 21. The maintenance exhibit does not include maintenance responsibilities for the basins, access roads, etc. Who will be responsible for each? 22. A pre-treatment facility will be required upstream of the underground infiltration facilities. 23. Additional comments will follow upon further information provided.
