LEAP 2023-04/Baker Industrial
WESTERN RIVERSIDE COUNTY MULTIPLE SPECIES
CONSERVATION PLAN CONSISTENCY FINDINGS
April 19, 2024
Background
Paragraph C of the Western Riverside County Multiple Species Conservation Plan (MSHCP)
Section 6.1.1 (Property Owner Initiated Habitat Evaluation and Acquisition Negotiation Strategy
[HANS]) establishes procedures regarding the evaluation of properties for which a development
application is not filed and states that “(1) Initial Application Review - Applications for proposed
projects which are within the Criteria Area shall be subject to an initial review to determine if all or
part of the property is necessary for inclusion in the MSHCP Conservation Area.” The subject
application (LEAP 2023-04) was submitted to the City of Lake Elsinore (City) for such a
determination.
The following analysis and findings are based upon text found in the MSHCP and site-specific
documentation from the following documents:
• “Western Riverside County Multiple Species Habitat Conservation Plan Consistency
Analysis – Baker Industrial” dated February 2024, prepared by Glenn Lukos Associates,
Inc.
• “Determination of Biologically Equivalent or Superior Preservation (DBESP) Analysis for
Impacts to MSHCP Riparian/Riverine Areas and Vernal Pools, and Narrow Endemic/
Criteria Area Plants – Baker Industrial Project” dated February 2024, prepared by Glenn
Lukos Associates, Inc.
Project Site Description
The LEAP 2023-04/Baker Industrial Project (Project) site comprises approximately 124.60 acres
in the City of Lake Elsinore, Riverside California [Figure 1 – Regional Map] and is located within
an un-sectioned portion of Township 5 South, Range 5 West, of the U.S. Geological Survey
(USGS) 7.5-minute quadrangle map Lake Elsinore, California [Figure 2– Vicinity Map]. The
Project site is located southwest of Interstate-15, the Lake Elsinore Outlet Center and Temescal
Creek/Collier Marsh. The Project site includes the following Assessor’s Parcel Numbers (APNs):

The ground elevation at the Project site ranges from 1,310 above mean sea level (AMSL) to 1,455
feet AMSL.
Soils within the Onsite portion of the Project site consist mainly of Lodo Rocky Loam and Willows
Silty Clay (saline-alkali). The Willows soils occur in the lower portions of site, with the rocky loam
soil occurring in the higher elevation areas. The Willows soils extend into the site from the adjacent
Collier Marsh area. These alkaline soils are strongly associated with the plant species that occur
in the vernal pools located immediately northeast of Baker Street. The “Offsite” (undeveloped)
portions of the Project site predominantly consist of fine sandy loam soils. The proposed RCA
Conserved Lands consist of Willows silty clay soils as well as the fine sandy loam soils.

Development Project Description
The overall Project site totals 124.60 acres and consists of five components:
1. The Industrial Project development footprint (referred to as the “Onsite” portion of the
Project)
2. Baker Street Improvements (Offsite)
3. A proposed City Maintenance Area (Offsite) – to be located along the edge of Baker
Street
4. Additional Street Improvements (Offsite) – includes improvements to Pierce Street and
Nichols Road
5. RCA Conserved Lands – includes 33.66 acres of lands to be conserved by the Project
located northeast of the proposed City Maintenance Area and southeast of Pierce
Street/Nichols Road
The Onsite Project consists of two industrial buildings (approximately 1,002,000 square feet of
industrial space) and associated improvements including vehicle parking fields, additional trailer
parking field, storm water drainage and treatment, and water and sewer lines.
33.66 acres of land will be set aside for conservation and deeded to the RCA. The RCA
Conservation Lands portion is bordered by the Baker Street, Pierce Street and Nichols Road
improvements. (See Figure 3, Site Plan).
The Project is part of the City’s Business District.

Findings
1. Development of the Project site would be a project under the City’s MSHCP Resolution,
and the City would be required to make an MSHCP Consistency finding before approval of
a development application.
The Project site is located within MSHCP Criteria Cells Pursuant to the City’s MSHCP
Resolution, the Project has been reviewed for MSHCP consistency, including consistency with
“Other Plan Requirements.” These include the Protection of Species Associated with
Riparian/Riverine Areas and Vernal Pool Guidelines (MSHCP, § 6.1.2), Protection of Narrow
Endemic Plant Species Guidelines (MSHCP, § 6.1.3), Additional Survey Needs and
Procedures (MSHCP, § 6.3.2), Urban/Wildlands Interface Guidelines (MSHCP, § 6.1.4),
Vegetation Mapping (MSHCP, § 6.3.1) requirements, Fuels Management Guidelines
(MSHCP, § 6.4), and payment of the MSHCP Local Development Mitigation Fee (MSHCP
Ordinance, § 4).
2. The proposed Project is subject to the City’s LEAP and the County’s Joint Project Review
processes.
Approximately 1.61 acres of the project site is located in Criteria Cell 4157, 71.27 acres of the
Project site is located in Criteria Cell 4166 and approximately 1.26 and 4.83 acres of the
8
Project site are located in Criteria Cells 4060 and 4067 respectively, which are part of Cell
Group W. The Project site is located in the MSHCP Elsinore Area Plan, Subunit 3 (Elsinore).
Therefore, a formal and complete LEAP application, LEAP 2023-04 was submitted to the City
on June 13, 2023.
3. The proposed Project is consistent with the Riparian/Riverine Areas and Vernal Pools
Guidelines.
Glenn Lukos Associates, Inc. (GLA) conducted field surveys April 2020, February, April and
July 2021, and April and July 2022 to identify and map riparian/riverine areas and vernal pools
within the Project site.
The Project site contains approximately 3.03 acres of MSHCP riparian/riverine areas,
including 2.36 acres of riparian habitats associated with Alberhill Creek, and 0.67 acre
associated with six drainage features (Drainage A through F). Approximately 2.58 acres of
riparian/riverine areas are inside Criteria Cells and 0.45 acre of riverine areas are outside
Criteria Cells. The 2.36 acres associated with Alberhill Creek includes 1.14 acres of Southern
Willow Riparian Scrub, 0.73 acre of Alkali Playa, 0.09 acre of Open Water, and 0.40 acre of
Semi-Natural Herbaceous Grassland.
The proposed Project will permanently (directly) impact approximately 0.50 acre of MSHCP
riverine areas but will not impact any riparian habitat. Impacts will occur to five drainage
features (A, B, C, D and F). These impacts could not feasibly be avoided due to the hydrology
and storm water requirements of the proposed Project. The Determination of Biological
Equivalent or Superior Preservation (DBESP) demonstrates that impacts to riverine areas
have been minimized to the fullest extent practicable and that proposed mitigation will result
in biologically superior conditions compared to the current conditions. Table 2 summarizes
Project impacts to riverine features.

Drainage D 0 0.09 0.09
Drainage F 0 0.20 0.20
Total 0.05 0.45 0.50
The Project will mitigate impacts to 0.50 acre of riverine areas offsite through the purchase of
mitigation credits from the Riverpark Mitigation Bank. The mitigation credits will include a
minimum of 1:1 of re-establishment and 2:1 of re-establishment and/or re-habilitation. Since
the Riverpark Mitigation Bank involves the restoration of areas adjacent to the San Jacinto
River, the mitigation bank lands provide hydrologic functions to the San Jacinto River
floodplain similar to the functions provided by drainage features to be impacted at the Project
site that are tributary to the Alberhill Creek floodplain. As a matter of habitat replacement, the
purchase of 1.50 acres of mitigation credits (1:1 of re-establishment and 2:1 of re-
establishment and/or re-habilitation) will be biologically superior compared with the impacts.
Vernal Pools
The Project site contains three areas on the northeastern side of Baker Street that pond
seasonally and exhibit the three wetland parameters to meet the definition of MSHCP Vernal
Pools. These areas are referenced herein as Vernal Pools 1, 2, and 3, all of which are inside
Criteria Cells.
The Project will permanently impact up to 0.08 acre of vernal pools including 0.01 acre of
Vernal Pool 2 and 0.07 acre of Vernal Pool 3 along the southern edge because of constructing
the storm drain outlets along the edge of the Baker Street improvements although much, if
not all, of the impacts might be temporary. The southern edge of Vernal Pool 3 will be
recontoured following the completion of construction of the Baker Street improvements and
the storm drain outlets, and the vernal pool is included in the Project’s proposed RCA
Conserved Land. The potential impact to Vernal Pool 2 is limited to 0.01 acre at the southern
edge, and it is expected that work limits will be adjusted in the field under the supervision of
the Project Biologist to fully avoid Vernal Pool 2. Vernal Pool 1 will be avoided by the Project,
Both Vernal Pools 1 and 2 will also be part of the RCA Conserved Land.
In order to reduce indirect effects to Vernal Pool 3, the Project will construct the two storm
drain outlets and configure the post-Project hydrology in a manner that will mimic the existing
10
conditions to the maximum extent feasible. The outlets will be constructed approximately 250
feet apart from each other and will collectively release water such that runoff will be spread
between the two outlets and into the vernal pool similar to the existing condition.
Following the completion of construction, the southern edge of Vernal Pool 3 will be re-
contoured and any portion of the 0.07-acre impacts that are temporary will be restored.
Although this impact area includes 0.01 acre of Vernal Pool 2, it is expected that the work
area limits will be adjusted in the field under the supervision of the Project Biologist to fully
avoid Vernal Pool 2. Any permanent impacts to the vernal pools will be mitigated by expanding
Vernal Pool 3 on the opposite side from the impacts through recontouring and revegetating.
The vernal pool will be expanded by at least a 3:1 ratio versus the permanent impacts.
Assuming up to 0.08-acre permanent impacts, the vernal pool will be expanded by 0.25 acre.
A Habitat Management and Monitoring Plan (HMMP) will be prepared to address the vernal
pool mitigation, including site preparation, non-native plant removal (if applicable),
maintenance, success criteria, and monitoring. The monitoring will include hydrologic
monitoring to confirm that the recontoured areas inundate sufficiently to support wetland
conditions. The HMMP will be provided to the RCA and Wildlife Agencies for review and
approval.
The Project is therefore consistent with the Riparian/Riverine Areas and Vernal Pool
Guidelines set forth in Section 6.1.2 of the MSHCP.
4. The proposed Project is consistent with the Protection of Narrow Endemic Plant Species
Guidelines.
The Project site occurs within the Narrow Endemic Plant Species Survey Area (NEPSSA) for
the following target species:
• Munz’s onion (Allium munzii)
• San Diego ambrosia (Ambrosia pumila)
• Slender-horned spineflower (Dodecahema leptoceras)
• Many-stemmed dudleya (Dudleya multicaulis)
• Spreading navarretia (Navarretia fossalis)
• California Orcutt grass (Orcuttia californica)
• San Miguel savory (Clinopodium chandleri)
• Hammitt’s clay-cress (Sibaropsis hammittii)
• Wright’s trichocoronis (Trichocoronis wrightii var. wrightii).
GLA biologists performed general and focused plant surveys for the Project site in both 2020
and 2022. One Narrow Endemic Plant species (San Diego ambrosia) was detected at the
Project site. San Diego ambrosia was detected in several locations, including two locations
in the southern end of the site (most of the plants within the Project site), one location in the
central portion of the site, three small locations adjacent to Pierce Street, and one small
11
location adjacent to Nichols Road. GLA biologists estimated 9,000 plants over 0.44 acre of
habitat with long-term conservation value for the species.
The Project will impact San Diego ambrosia in several locations, including in the southern
portion of the Industrial footprint (Onsite) and within the proposed offsite road improvements
along Pierce Street and Nichols Road.
All impacts to plant habitat with long-term conservation value will be mitigated within the
proposed RCA Conserved Lands. To mitigate the loss of 0.44 acre of habitat with long-term
conservation value for San Diego ambrosia, the Project will restore approximately 1.25 acres
of degraded habitat in the Alberhill Creek floodplain with San Diego ambrosia. The proposed
restoration area consists of an area dominated by non-native grasses and forbs where San
Diego ambrosia was detected in the past but due to overgrowth by invasive vegetation, San
Diego ambrosia was not detected during plant surveys for the Project. The Project will develop
a HMMP that will identify site preparation methods, the proposed plant palette, proposed
success criteria, and maintenance/long-term monitoring procedures. The HMMP will be
submitted to the City, RCA, United States Fish and Wildlife Service (USFWS), California
Department of Fish and Game (CDFW) and the Regional Water Quality Control Board for
review and approval prior to implantation of the proposed mitigation.
The proposed Project provides preservation and mitigation for San Diego ambrosia that is
biologically superior to the current conditions and is therefore consistent with the Protection
of Narrow Endemic Plant Species Guidelines.
5. The proposed Project is consistent with the Additional Survey Needs and Procedures.
The MSHCP requires additional surveys for certain species if the project is located in certain
locations. Pursuant to MSHCP Figure 6-2 (Criteria Area Species Survey Area), Figure 6-3
(Amphibian Species Survey Areas with Criteria Area), Figure 6-4 (Burrowing Owl Survey
Areas with Criteria Area), and Figure 6-5 (Mammal Species Survey Areas with Criteria Area),
burrowing owl surveys are required for the subject property prior to approval of a development
proposal.
The property is not located within survey areas for criteria area species (MSHCP Figure 6-2),
amphibian species (MSHCP Figure 6-3), or mammal species (MSHCP Figure 6-5) and
surveys for those species are not required.
Burrowing Owl
The Project site is located within the MSHCP Survey Area for the burrowing owl. GLA
conducted a burrowing owl (Athene cunicularia) habitat assessment and focused borrow
survey in 2020 and 2022 and focused owl surveys on March 9, April 4, May 2, and June 3,
2022. No burrowing owls were detected within the Project site during focused surveys.
12
As a mitigation measure for the proposed Project, the City will require a pre-construction
presence/absence survey for burrowing owl to be conducted within 30 days of the
commencement of project-related grading or other land disturbance activities to ensure that
the species has not moved onto the site since completion of the surveys. The pre-construction
survey should occur within 30 days prior to ground disturbing activity. Owls located as a result
of survey efforts will be relocated. If burrowing owl have colonized the Project Onsite or the
Offsite improvements area prior to the initiation of construction, the project proponent should
immediately inform the City, RCA and the Wildlife Agencies, and coordinate on the potential
need for preparation, review and approval of a Burrowing Owl Protection and Relocation Plan,
prior to any ground disturbance.
Therefore, the subject project is consistent with the Additional Survey Needs and Procedures
of the MSHCP.
6. The proposed Project is consistent with the Urban/Wildlands Interface Guidelines.
Section 6.1.4 of the MSHCP sets forth guidelines that are intended to address indirect effects
associated with locating development in proximity to the MSHCP Conservation Area, where
applicable.
The guidelines in Section 6.1.4 of the MSHCP are intended to address indirect effects
associated with development near MSHCP Conserved Areas. Developments in proximity to
MSHCP Conserved Areas may result in “edge effects” that might adversely affect biological
resources within MSHCP Conserved Areas.
According to the MSHCP development may occur adjacent to Conservation Areas. Future
Development in proximity to Conservation Areas may result in Edge Effects that will adversely
affect biological resources within the Conservation Areas. To minimize such Edge Effects, the
Project Applicant will be required to follow the Urban/Wildlands Interface Guidelines in Section
6.1.4 of the MSHCP to minimize urban/wildlands interface issues in the nearby Criteria Area.
These include measures related to indirect impacts such as water quality (drainage), use of
toxics, night lighting, indirect noise, invasive plant and wildlife species, protection of habitat
areas (barriers), and grading/land development adjacent to habitat areas.
Drainage
Pursuant to the Urban/Wildlife Interface Guide (UWIG), proposed developments in proximity
to the MSHCP Conservation Area shall incorporate measures, including measures required
through the National Pollutant Discharge Elimination System (NPDES) requirements, to
ensure that the quantity and quality of runoff discharged to the MSHCP Conservation Area is
not altered in an adverse way when compared with existing conditions.
The Project includes the preparation of a Preliminary Hydrology Study to analyze the existing
condition storm flows across the property as well as the proposed condition conveyances to
existing discharge locations. The hydrology study will confirm flow values based on standard
13
storm intensities and discharge volumes, flow rates, and velocities. The Project also includes
a Preliminary Water Quality Management Plan (WQMP) that identifies the Best Management
Practices (BMPs) proposed to be implemented to treat project related pollutants for onsite and
offsite impervious improvements. The WQMP will identify the post-construction treatment
control and site design BMPs to treat specific pollutants from onsite impervious areas as well
as the public right-of-way prior to discharge at historical locations on the northern side of the
proposed Baker Street corridor improvements. BMPs located within the public right-of-way of
Baker Street and Nichols Road will treat roadway specific pollutants within bio-
retention/modular wetland facilities upstream of the specified discharge locations. A Storm
Water Pollution Prevention Plan (SWPPP) will be prepared and implemented prior to onsite
and offsite project construction disturbance. The SWPPP will focus on the design, installation,
and treatment of construction related pollutants. The SWPPP document will be approved
through the State of California and the Project will be registered as required by the
Construction General Permit. The Project will be monitored before, during and after rain
events to ensure BMP implementation and effectiveness in protecting downstream habitats
and receiving water bodies.
Toxics
The UWIG states that land uses proposed in proximity to the MSHCP Conservation Area that
use chemicals or generate bioproducts such as manure that are potentially toxic or may
adversely affect wildlife species. Habitat or water quality shall incorporate measures to ensure
that application of such chemicals does not result in discharge to the MSHCP Conservation
Area. Measures such as those employed to address drainage issues will be implemented for
toxics.
The proposed Project will implement a SWPPP that will address runoff during construction.
Lighting
Night lighting shall be directed away from the MSHCP Conservation Area to protect species
within the MSHCP Conservation Area from direct night lighting. Shielding shall be
incorporated in project designs to ensure ambient lighting in the MSHCP Conservation Area
is not increased.
The Project will incorporate an onsite lighting design that provides the required lighting levels
for normal operation onsite. Exterior lighting can be designed as downward facing to prevent
unnecessary foot candles outside of the Project boundary. The City of Lake Elsinore requires
public streetlights every 200 feet on both sides of newly constructed public roadways per Lake
Elsinore standards 503 and 508. The Project proponent will work with the City to design a
public roadway lighting design that is sensitive to neighboring sensitive receptors.
Noise
The UWIG states “Proposed noise generating land uses affecting the MSHCP Conservation
Area shall incorporate setbacks, berms or walls to minimize the effects of noise on MSHCP
14
Conservation Area resources pursuant to applicable rules, regulations and guidelines related
to land use noise standards. For planning purposes, wildlife within the MSHCP Conservation
Area should not be subject to noise that would exceed residential noise standards.”
The Project intends to provide Good Neighbor Policy screening to reduce noise impacts to
neighboring properties. In addition, the City of Lake Elsinore Good Neighbor Policy requires
additional edge condition screening along public right-of-way that will help reduce normal
operation noise levels due to the placement of upgraded landscaping and fencing. A noise
analysis will be prepared along with other environmental impact studies to determine project
related noise impacts. If noise levels exceed neighboring sensitive receptor levels, the study
will identify mitigations of condition and implement to achieve acceptable noise levels.
Invasives
Plant species acceptable for the Project’s landscaping must not be considered an invasive
species pursuant to Table 6-2 of the MSHCP. To ensure this, the final landscape plans must
be reviewed and verified by the City for consistency with the plant species list in Table 6-2 of
the MSHCP. Allowable use of invasive species on a project site is based on the proximity of
the plantings to the Conservation Area, the sensitivity of resources in the Conservation Area
to invasion, and barriers to plant and seed dispersal. If the site is sufficiently contained such
that invasive plantings would not be able to spread outside of the developed Project footprint,
invasive plantings may be allowed on the site. However, the City will make the final decision
on the suitability of this species for the Project’s landscape plan.
Barriers
According to the UWIG, proposed land uses adjacent to the MSHCP Conservation Area shall
incorporate barriers, where appropriate in individual project designs to minimize unauthorized
public access, domestic animal predation, illegal trespass or dumping in the MSHCP
Conservation Area. Such barriers may include native landscaping, rocks/boulders, fencing,
walls, signage and/or other appropriate mechanisms.
Barriers would restrict direct access to the MSHCP Conservation Area from the project site
by unauthorized public access or domestic animals. Under the MSHCP, suitable barriers
include native landscaping, rocks/boulders, fencing, walls, signage, and/or other appropriate
mechanisms. The barriers would and should be placed within the boundaries of the
development and will be outside of the confines of the open space/MSHCP Conservation
Area.
Grading/Land Development
The UWIG states, “Manufactured slopes associated with proposed site development shall not
extend into the MSHCP Conservation Area.”
Manufactured slopes associated with proposed site development shall not extend into the
MSHCP Conservation Area. No manufactured slopes are anticipated to be constructed within
the MSHCP Conservation Area. Should manufactured slopes be necessary, they will be kept
15
within the boundaries of the development footprint and not encroach into the MSHCP
Conservation Area.
For these reasons, the subject project is consistent with the UWIG.
7. The proposed project is consistent with the Vegetation Mapping requirements.
GLA mapped nine distinct vegetation/land use types for the Project site, including Akali
Grassland, Akali Playa, Disturbed/Developed, Open Water, Riversidean Sage Scrub, Semi-
Natural Herbaceous Grassland, Disturbed Semi-Natural Herbaceous Grassland, Southern
Willow Scrub and Vernal Pool. One natural plant community is supported by the Project site:
Riversidean Sage Scrub (RSS). In addition, the site supports two (2) land cover types that
would be classified as disturbed and developed. (See Figure 4, Vegetation). The land cover
types are described in further detail below.
Alkali Grassland
Alkali grassland covers 4.06 acres of the Project site on the northeast side of Baker Street,
primarily surrounding and/or associated with the vernal pools. Soil within these areas is
mapped as Willows silty clay, which consists of well-drained, moderately slow permeable
soils. Alkali grassland within the Project site includes alkali adapted plant species as well as
rare plants. Dominant species within the meadow and marsh vegetation community include
alkali weed (Cressa truxillensis), silverscale saltbush (Atriplex argentea), alkali mallow
(Malvella leprosa), Harding grass (Phalaris aquatica), neckweed (Veronica peregrina), and
foxtail barley (Hordeum murinum). This vegetation category also supports a variety of special-
status plants including Coulter's goldfields (Lasthenia glabrata ssp. coulteri), San Jacinto
valley crownscale (Atriplex coronata var. notatior), and vernal barley (Hordeum intercedens).
Alkali Playa
The Project site contains 0.73 acre of alkali playa, all of which occurs within the proposed
RCA Conserved Land. Alkali playas are also dry lakes or edges of dry lakes that typically
undergo periods of temporary inundation during the wet season and have high concentrations
of alkali salts (Holland 1986). As such, alkali playas are dominated by plant species adapted
to a salty substrate.
The disturbed alkali playa within the Project site is located within the Alberhill Creek floodplain.
Dominant species include alkali weed, alkali heath (Frankenia salina), salt grass, silverscale
saltbush, and bush seepweed (Suaeda nigra). The alkali playa vegetation community within
the Project site supports several rare plant species including Coulter’s goldfields, San Jacinto
Valley crownscale, and vernal barley.
16
Disturbed/Developed
The Project site contains 18.34 of disturbed/developed land consisting of paved roads,
unpaved access roads, and former residential lots. The disturbed/developed areas occur
primarily along Baker Street, both within RCA conserved land and impact areas. The
disturbed/developed portions of the site remain generally unvegetated, although ruderal
species occur intermittently within and along the edges of these areas. Dominant species
include coastal heron’s bill (Erodium cicutarium), Russian thistle (Salsola tragus), London
rocket (Sisymbrium irio), cheeseweed (Malva parviflora), and summer mustard (Hirschfeldia
incana).
Open Water
The Project site contains open water, covering approximately 0.09 acre. This land use type
consists of a perennial portion of Alberhill Creek which flows through the northern limit of RCA
conserved lands.
Riversidean Sage Scrub
A 3.01-acre patch of California Buckwheat Scrub occurs in the southwestern portion of the
Project site. This intact vegetation community occurs on a steep slope, contains clay soils,
and exhibits environmental characteristics typical of sage scrub communities such as spaced
apart shrubs providing an open canopy to allow for interspersed growth of grasses and forbs.
The Riversidean Sage Scrub vegetation community is dominated by shrub species including
brittlebush (Encelia farinosa), California sagebrush (Artemisia californica), black sage (Salvia
mellifera), and California buckwheat (Eriogonum fasciculatum). The understory consists of
lower growing shrubs and perennial and annual herbs such as common sandaster
(Corethrogyne filaginifolia), clustered tarweed (Deinandra fasciculata), blue dicks
(Dichelostemma capitatum), wild cucumber (Marah macrocarpa), California plantain
(Plantago erecta), and splendid mariposa (Calochortus splendens). Non-native grasses also
occur in the understory including common Mediterranean grass (Schismus barbatus) and
various brome species (Bromus spp.).
Semi-Natural Herbaceous Grassland
The majority of the Project site consists of semi-natural herbaceous grassland. This vegetation
community comprises 69.71 acres and occurs throughout the entirety of the site, in both RCA
conserved lands and impact areas. Although these areas currently remain largely
undisturbed, the overall plant community exhibits significant historic disturbance that removed
the mosaic of native plants that would have otherwise been present and replaced it with exotic
species. As such, due to the current predominance of non-native species, the term “semi-
natural” is used to describe this herbaceous grassland.
In early spring, before annual grasses emerge, this vegetation community is dominated with
common fiddleneck (Amsinckia intermedia), London rocket, cheeseweed, and coastal heron’s
bill. Also present in early spring are sporadically occurring patches of native wildflowers
17
including lupine (Lupinus bicolor), chick lupine (Lupinus microcarpus), goldfields (Lasthenia
californica), and red maids (Calandrinia menziesii). Then, in late spring and early summer,
this vegetation community is almost entirely dominated with non-native grass species
including red brome (Bromus rubens), ripgut brome (Bromus diandrus), foxtail barley, and slim
oat (Avena barbata).
Disturbed Semi-Natural Herbaceous Grassland
The Project site contains 26.27 acres of land mapped as disturbed semi-natural herbaceous
grassland. This vegetation community occurs in the central portion of the site, bordering Baker
Street on both sites, and also occurs in both RCA conserved lands and impact areas. It is
nearly identical to the vegetation community described above (semi-natural herbaceous
grassland); however, these areas currently experience more disturbance in the form of routine
mowing and disking. As such, the disturbed semi-natural herbaceous grassland excludes
pockets of native wildflowers and any semblance of a historic native plant community.
The disturbed semi-natural herbaceous grassland is dominated with a variety of weedy,
annual species including summer mustard, stinknet (Oncosiphon piluliferum), prickly lettuce
(Lactuca serriola), London rocket, cheeseweed, coastal heron’s bill, red brome, ripgut brome,
foxtail barley, and slim oat.
Southern Willow Riparian Scrub
The Project site contains 1.14 acres of southern willow riparian scrub as part of RCA
conserved land, within and adjacent to Alberhill Creek. Southern willow riparian scrub consists
of dense, broadleaved, winter-deciduous stands of trees dominated by shrubby willows (Salix
spp.) in association with mule fat (Baccharis salicifolia). This vegetation community contains
an assortment of young and mature trees, with willows ranging from 15- to 50-feet tall and is
dominated by black willow (Salix gooddingii), red willow (Salix laevigata), and arroyo willow
(Salix lasiolepis). Other species sporadically observed in association with this plant
community include mule fat (Baccharis salicifolia), tamarisk (Tamarix ramosissima), western
ragweed (Ambrosia psilostachya), big saltbush (Atriplex lentiformis), saltgrass (Distichlis
spicata), and yerba mansa (Anemopsis californica).
Vernal Pools
Three vernal pools occur within the Project site on the northeast side of Baker Street,
accounting for 1.25 acres. Vernal pools are ephemeral wetlands that form in shallow
depressions underlain by a substrate near the surface that restricts the downward percolation
of water. Depressions in the landscape fill with rainwater and runoff from adjacent areas during
the winter and may remain inundated until spring or early summer, sometimes drying more
than once during the wet season. Smaller pools can fill, and dry, and larger pools can hold
water longer and may, in the deeper portions, support species that are more representative
of freshwater marshes. Vernal pools are well-known for their high level of endemism (Stone,
1989) and abundance of rare, threatened, or endangered species (Sawyer and Keeler-Wolf,
18
1995). Vernal pools are dominated by native annual plants, with low to moderate levels of
perennial herbaceous cover (MSHCP 2023).
Within the Project site, the northernmost seasonal pool (Vernal Pool 3) is partially supported
by runoff from an adjacent ephemeral drainage, while the remaining two pools (Vernal Pool 1
and 2) are depressional features that inundate from direct rainfall and runoff from the
immediate local watershed. Dominant plant species within the pools include alkali
plagiobothrys (Plagiobothrys leptocladus), alkali weed, alkali mallow, common toad rush
(Juncus bufonius), and Harding grass (Phalaris aquatica). This vegetation category also
supports a variety of special-status plants within the Project site including Coulter's goldfields,
small-flowered microseris (Microseris douglasii ssp. platycarpha), San Jacinto Valley
crownscale, and vernal barley.
This mapping is sufficient under the MSHCP and is consistent with the MSHCP vegetation
mapping requirements.
8. The proposed project is consistent with the Fuels Management Guidelines.
Section 6.4 of the MSHCP requires that new developments adjacent to the MSHCP
Conservation Area or other undeveloped lands incorporate any fuel/brush management zones
and Best Management Practices.
The Project will be required to incorporate the BMPs outlined in Volume I, Appendix C of the
MSHCP as part of the development pursuant to regulatory requirements.
Therefore, the Project is consistent with the Fuels Management Guidelines as set forth in
Section 6.4 of the MSHCP.

Residential, density between 8.0 and 14.0 dwelling units per acre $1,766 per dwelling unit
Residential density greater than 14.0 dwelling units per acre $781 per dwelling unit
Commercial $19,066 per acre
Industrial $19,066 per acre
10. The proposed project is consistent with the MSHCP Reserve Assembly Requirements.
MSHCP Sequential Approach
The MSHCP describes a sequential approach to application of the Reserve Assembly
guidance provided in the MSHCP (MSHCP, page 3-122 through 3-124). The Project can be
shown to be consistent with the MSHCP Reserve Assembly Requirements on an Area Plan
and Area Plan Subunit Basis as outlined below.
Step 1 – Examine the Project in the context of the overall MSHCP Conservation Area by
relating the Project to the MSHCP Conservation Area description in Section 3.2.2 of
the Plan and the descriptions of the applicable Cores and Linkages in Section 3.2.3
of the Plan. (MSHCP, page 3-122)
Section 3.2.2 of the MSHCP summarizes the MSHCP Conservation Area in terms of
bioregions, vegetation, soils, patch size and edge affected land. Section 3.2.2 also states,
“The MSHCP Conservation Area may also be described in terms of Cores and Linkages.”
(MSHCP, page 3-19). The following description of the Project site in the context of the overall
MSHCP Conservation Area is in terms of applicable Cores and Linkages.
Per the MSHCP, conservation within Cell 4166 will contribute to assembly of Proposed
Linkage 2. The MSHCP describes Proposed Linkage 2 as:
a) “Proposed Linkage 2”
Proposed Linkage 2 is comprised of wetland Habitat associated with Collier Marsh in the
City of Lake Elsinore. It supports key populations of the following species: yellow-breasted
21
chat, San Diego ambrosia, downy woodpecker, least Bell's vireo, yellow warbler and
southwestern willow flycatcher. Maintenance of wetland functions and values and water
quality of Collier Marsh is important for these species. As shown in Table 3 below, areas
not affected by edge within this Linkage total approximately 70 acres of the total 160 acres
occupied by this Linkage. Since this Linkage may be affected by edge, treatment and
management of edge conditions will be necessary to ensure that land uses adjacent to
the Linkage do not degrade water quality or inhibit floodplain processes. Guidelines
Pertaining to Urban/Wildlands Interface for the management of edge factors such as
lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this
document.

The Project will dedicate 30.11 acres of land in Cell 4166 to the MSHCP Conservation
Area, all of which are associated with Collier Marsh and adjacent areas. Additionally, the
Project will implement Section 6.1.4 Guidelines Pertaining to Urban/Wildlands Interface
as discussed in Section 6 of this document.
Approximately 6.09 acres of the Project site is within Cell Group W (1.26 acres in Cell#
4060 and 4.83 acres in Cell# 4067), consisting of offsite improvements to Nichols Road
from the proposed intersection with Baker Street on the west to the existing Collier Road
intersection on the east. The MSHCP Criteria for the Cell Group states that Conservation
within this Cell Group will contribute to assembly of Proposed Core 1. The MSHCP
describes Proposed Core 1 as:
“Proposed Core 1”
Proposed Core 1 is located approximately in the east-central region
of the Plan Area. This Core Area consists largely of private lands in
the Alberhill area but also contains small pieces of Public/Quasi-
22
Public Lands. The Core exists in two blocks, one east and one west
of I-15. Connections are made from the Core to Proposed Linkage
1, Proposed Linkage 2 (Alberhill Creek), Proposed Linkage 3, and
Existing Core C (Lake Mathews/Estelle Mountain). The Core
provides Habitat for species and also provides for movement of
species. Key populations of coastal California gnatcatcher, Munz’s
onion, many-stemmed dudleya, cactus wren, tricolored blackbird,
and yellow warbler are supported in this Core Area. The Core likely
provides for movement of common mammals such as bobcat. Since
this Core is contiguous with Existing Core C (Lake Mathews/ Estelle
Mountain) via an approximately 10,000-foot connection, the
functional area of the Core is much greater than 7,470 acres
reported in Table 2, below. Because a portion of the Core is
surrounded by city (Lake Elsinore) and community development
planned land uses, and since this Core may be affected by the
proposed Hemet to Corona/Lake Elsinore Community and
Environmental Transportation Acceptability Process (CETAP)
Corridor, management of edge conditions in these areas will be
needed to maintain high quality Habitat within the Core. Guidelines
Pertaining to Urban/Wildlands Interface for the management of
edge factors such as lighting, urban runoff, toxics, and domestic
predators are presented in Section 6.1 of this document.
As shown on Table 4 below, 6,350 acres of the total 7,470 acres
occupied by Core 1 are not affected by edge. Adjacent planned land
uses and major Covered Activities traversing the Linkage may affect
resources within the Linkage. Adjacent planned land uses for
Proposed Core 1 include City (Lake Elsinore), Rural Mountainous,
Community Development, Open Space/ Conservation. Land use
activities within the City and Community Development designation
may result in Edge Effects associated with fire suppression, fire,
and dispersal of invasive species. Guidelines Pertaining to
Urban/Wildlands Interface for the management of edge factors
such as lighting, urban runoff, toxics, and domestic predators are
presented in Section 6.1 of this document.

Step 2 – Identification of the specific Area Plan and Area Plan Subunit within which the
particular project is located. Planning Species and Biological Issues and
Considerations as well as variable target acreages for the overall Area Plan and
Area Plan Subunit should be reviewed between Permittee staff and the applicant
along with any variable project specific biological information. Planning Species and
Biological Issues and Considerations that apply to the specific project should be
identified. Not all Planning Species and Biological Issues and Considerations for
particular Area Plan or Area Plan Subunit will apply to every project. (MSHCP, page
3-122)
A majority of the Project site (71.27 acres) is located within Subunit 3 (Elsinore) of the
Elsinore Area Plan. Another 7.70 acres of the Project site is located within Subunit 2
(Alberhill) of the Elsinore Area Plan. The remainder of the Project site (45.63 acres) is
outside of the Criteria Area.
Subunit 3 (Elsinore) has a target acreage range for Additional Reserve Lands 925-1,815
acres. It includes the following list of biological issues and considerations that relate to the
conservation goals of the MSHCP:
• Conserve wetlands including Temescal Wash, Collier Marsh, Alberhill Creek, Lake
Elsinore and the floodplain east of Lake Elsinore (including marsh Habitats) and
maintain water quality.
• Conserve clay soils supporting Munz's onion.
24
• Conserve Travers-Willow-Domino soil series.
• Conserve foraging Habitat for raptors, providing a sage scrub-grassland ecotone.
• Conserve grassland Habitat for mountain plover.

• Maintain opportunities for Core and Linkage Habitat for Quino checkerspot butterfly.
The Project will dedicate 30.11 acres of land in Subunit 3, associated with Cell 4166, to
the MSHCP Conservation Area, which will contribute to Proposed Linkage 2 as well as
the following biological issues and considerations identified for Subunit 3.
• Conserve wetlands including Temescal Wash, Collier Marsh, Alberhill Creek, Lake
Elsinore and the floodplain east of Lake Elsinore (including marsh Habitats) and
maintain water quality.
• Conserve Travers-Willow-Domino soil series.
• Conserve foraging Habitat for raptors, providing a sage scrub-grassland ecotone.
• Conserve grassland Habitat for mountain plover.
• Conserve breeding Habitat for northern harrier.
• Maintain linkage area for bobcat.
• Conserve San Diego ambrosia at Alberhill and Nichols Road or find new populations
that would allow for loss of known populations.
• Maintain opportunities for Core and Linkage Habitat for Quino checkerspot butterfly.
Subunit 2 (Alberhill) has a target acreage range for Additional Reserve Lands of 1,760-
3,010 acres. It includes the following list of biological issues and considerations that relate
to the conservation goals of the MSHCP:
• Provide Core Areas for the California gnatcatcher within suitable Habitat east and
west of I-15.
• Provide a northwest-southeast connection along the hills between Estelle Mountain
and Sedco Hills, primarily for coastal California gnatcatchers, but also other sage
scrub species.
• Conserve alkali soils supporting sensitive plants such as San Diego ambrosia, vernal
barley and Coulter's goldfields.
• Conserve clay soils supporting sensitive plants such as Munz's onion, many-
stemmed dudleya, small-flowered morning glory and Palmer's grapplinghook.
• Conserve wetlands including Temescal Wash and Alberhill Creek.
• Maintain upland Habitats in Alberhill and provide connection north to Estelle
Mountain, North Peak, and BLM Lands.
25

• Conserve foraging Habitat for raptors, providing a sage scrub-grassland ecotone.
• Maintain Core and Linkage Habitat for bobcat.
• Maintain Core and Linkage Habitat for mountain lion east of I-15.
• Maintain Core and Linkage Habitat for Stephens' kangaroo rat east of I-15.
• Maintain Core Area for Riverside fairy shrimp.
• Maintain opportunities for Core and Linkage Habitat for Quino checkerspot butterfly.
The Project will dedicate 1.89 acres of land in Subunit 2, associated with Cell 4067 (Cell
Group W), to the MSHCP Conservation Area which will contribute to Proposed Core 1 as
well as the following biological issues and considerations for Subunit 2:
• Conserve alkali soils supporting sensitive plants such as San Diego ambrosia, vernal
barley and Coulter's goldfields.
• Maintain upland Habitats in Alberhill and provide connection north to Estelle
Mountain, North Peak, and Bureau of Land Management (BLM) Lands.
• Conserve foraging Habitat for raptors, providing a sage scrub-grassland ecotone.
• Maintain Core and Linkage Habitat for bobcat.
Step 3 – Review of the specific Criteria for the identified Cell or Cell Group within which the
Project site is located.
a) Pursuant to page 3-122 of the MSHCP, the “first criterion for each Cell or Cell Group
is the identification of the applicable Core or Linkage. This relationship of the project
to the applicable Core or Linkage should already have been identified and discussed
as part of the first steps in the sequential process.”
Criteria Cells and Cell Groups for which the proposed Project are located are described in
Table 5, below.

b) “The next criteria for each Cell or Cell Group” as described on page 3-122 of the
MSHCP “are the identification of Vegetation Communities toward which
Conservation should be directed along with connectivity requirements.”
Table 6 identifies the Project’s relation to the Criteria Cell/Criteria Group, below.
Table 6. Criteria by Cell or Cell Group
Criteria Cell Criteria Project’s Relation to Criteria
Cell/Cell Group
4157
Conservation within this Cell will
contribute to assembly of
Proposed Core 1. Conservation
within this Cell will focus on
coastal sage scrub, chaparral
and grassland habitat. Areas
conserved within this Cell will be
connected to coastal sage scrub
and chaparral habitat proposed
for conservation in Cell #4156 to
the west and to chaparral and
grassland habitat proposed for
conservation in Cell #4057 to the
north. Conservation within this
Cell will range from 45 percent to
55 percent of the Cell focusing in
the western half of the Cell.
The 1.61-acre portion of the
Project in Cell 4157 is in the very
northeastern corner of this Cell. It
supports mostly
Developed/Disturbed land
associated with Nichols Road
along with a small portion of
Disturbed Semi-Natural
Herbaceous Grassland. All of the
Project area within Cell 4157 is,
or will be, developed as part of
off-site improvements.
4166
Conservation within this Cell will
contribute to assembly of
Proposed Linkage 2.
Conservation within this Cell will
focus on meadow, marsh,
riparian scrub, woodland and
forest habitat along Alberhill
Creek and adjacent grassland
habitat. Areas conserved within
this Cell will be connected to
riparian scrub, woodland, forest
and grassland habitat proposed

4060 (Cell Group W)
Conservation Cell Group W will
contribute to assembly of
Proposed Core 1. Conservation
within this Cell Group will focus
on riparian scrub, woodland and
forest habitat associated with
Alberhill Creek and adjacent
coastal sage scrub and
grassland habitat. Areas
conserved within this Cell Group
will be connected to coastal sage
scrub, riparian scrub, woodland
and forest habitat proposed for

Cell Group will range from 80
percent to 90 percent of the Cell
Group focusing in the
northwestern portion of the Cell
Group.
The 6.09 acre portion of the
Project located in Cell Group W
is located in the far southern
portion of Cells 4060 and 4067.
Vegetation communities within
this portion of the Project area
include Disturbed/Developed,
Southern Willow Scrub,
Disturbed Semi-Natural
Herbaceous Grassland, and
Semi-Natural Herbaceous
Grassland. An approximately 52-
acre portion of Cell 4060, in the
northwest, northeast, and
southwest quadrangles of the
Cell, is MSHCP Conserved
Additional Reserve Lands.
4067 (Cell Group W)
c) “Finally, the project should be examined with respect to the percentage conservation
portion of the Cell Criteria, which is the last criterion provided for each Cell and Cell
Group.”. (MSHCP, pages 3-122 and 3-123)
Table 7 provides a breakdown of Project site acreages for those portions within the Criteria
Area and the Percentage Conservation Portion of the Cell Criteria.
1.61 acres of the Project site is located in the northeastern quadrant of Criteria Cell 4157,
consisting of Disturbed/Developed and Disturbed Semi-Natural Herbaceous Grassland
associated with Nichols Road. The Criteria for Cell 4157 call for conservation of
conservation of 45 percent to 55 percent, or 72 to 88 acres, of coastal sage scrub,
chaparral, and grassland habitat in the western half of the Cell. The Project will not develop
areas identified for conservation in Cell 4157.
71.27 acres of the Project site are located in the northwest, southwest, and southeast
quadrants of Criteria Cell 4166. The Criteria for Cell 4166 call for conservation of 10
percent to 20 percent, or 16 to 32 acres, of meadow, marsh, riparian scrub, woodland and
forest habitat in the northeastern portion of the Cell. Approximately 3.5 acres of Additional
Conservation Lands already exist in the eastern Portion of Cell 4166. The Project will
contribute 30.11 acres within Cell 4166 to the RCA for inclusion in the Conservation Area.
This exceeds the conservation acreage goal for the Cell. The portion of the Project within
28
Cell 4166 that will be developed for the Project is located in the southwestern portion of
the cell.
6.09 acres of the Project site are located in the southern portion of Cell Group W (Cells
4060 and 4067). The Criteria for Cell Group W call for conservation of 80 percent to 90
percent (384 to 432 acres) of riparian scrub, woodland and forest habitat associated with
Alberhill Creek and adjacent coastal sage scrub and grassland habitat. Approximately 51
acres of Additional Conservation Lands already exist in the northern and eastern Portion
of Cell Group W. The Project will contribute 1.89 acres of land consisting of grassland and
riparian scrub habitats within Cell 4067 for inclusion in the Conservation Area. The
remainder of the Project site (45.63 acres) is outside of the Criteria Area. Reserve
Assembly requirements for each independent Cell and Cell Group are described in Table
7 below.

MSHCP Covered Roads
The Project includes offsite roadway improvements to Nichols Road, which is a covered road
under the MSHCP.
Section 7 of the MSHCP describes covered Activities/Allowable Uses. Section 7.3.5
describes Planned Roads within the Criteria Area (“Covered Roads”) as “Planned roadways
are defined as either existing facilities that require improvements (i.e. widening) or a new
facilities to be constructed. Planned roadways include seven types of roadways, freeways,
CETAP Corridors and other major facilities that have been identified as part of the General
Plan circulation element. Planned roadways are depicted in a general fashion on the County
Circulation Element.” (MSHCP, Page 7-25) “Evaluations of planned roadways with respect to
Conservation of biological resources have been conducted throughout the MSHCP planning
29
process. As a result, only those planned roadways identified in this section are Covered
Activities within the Criteria Area. Roadways other than those identified in this section are not
covered without an amendment to the MSHCP in accordance with the procedures described
in Section 6.10 of this document.” (MSHCP, page 7-31)
The MSHCP states that “[t]he improvement/construction of circulation element roadways
shown on Figure 7-1 [of the MSHCP] are Covered Activities within the Criteria Area, as well
as the operation and Maintenance Activities conducted for these facilities. The Circulation
element roads included in Figure 7-1 and that are analyzed in this section include a composite
of County and Cities General Plan Circulation Elements.” (MSHCP, page 7-31) MSHCP
Figure 7-1 shows Railroad Canyon Road adjacent to the project site as an “Arterial” road with
a 128-foot right-of-way.
Improvements to Nichols Road will occur as part of the Project. Nichols Road improvements
will likely consist of an interim intersection with appropriate pavement tapering to the east and
west leading away from the new intersection with Baker Street. Minor roadway resurfacing
may be required along the existing Nichols Road segment between the Baker Street
intersection and the Collier Avenue intersection. The Nichols and Collier intersection may also
include minor surface improvements, revised lane striping and potential traffic control/signage
improvements. The Project impact footprint, (i.e., the Project limit of disturbance) includes all
areas needed to construct the improvements.
Conclusion
All development proposed within Criteria Cells is either located in areas not described for
conservation or consists of street improvements within existing developed roadways that will not
expand the existing roadway. In addition, the Project will conserve approximately 33.66 acres,
including 32.00 acres within the Criteria Area consisting of the northeastern portion of Cell 4166
and southern portion of Cell 4067, which includes and is adjacent to Alberhill Creek/Collier Marsh.
Therefore, the proposed development and conservation are consistent with the Reserve
Assembly requirements for the applicable Criteria Cells and the Project is consistent with the
MSHCP.
