1.0 SUMMARY
The project is a Tentative Parcel Map to subdivide 5.68 acres into four parcels plus a remainder parcel. The project
site is located at 9046 Westhill Road within the community of Lakeside, in the County of San Diego and the
unincorporated lands within the Metro-Lakeside-Jamul segment of the South County Multiple Species
Conservation Program (MSCP; Figure 1). This report provides information regarding existing conditions,
compliance with the County of San Diego Resource Protection Ordinance (RPO), County of San Diego Report
Format and Content Requirements, Biological Resources and the Biological Mitigation Ordinance (BMO; County
2010), and performs an impact analysis based on the current site design. This letter report also identifies any
potential mitigation measures to reduce any impacts to below a level of significance.
A general biological survey, sensitive species presence/potential survey and the Resource Protection Ordinance
(RPO) surveys were performed onsite. Biological resources observed include three (3) habitat types: Disturbed
coastal sage scrub, Disturbed habitat (graded, hydroseeded, mowed area) and Developed area (existing homes
and driveways).
No local, state or federally listed Endemic/Special Status plant or wildlife species was observed onsite.
One potentially significant biological impact is proposed to occur as a result of a potential loss of 0.16 acres of
disturbed coastal sage scrub. This habitat is not located within the grading/impact footprint and will be preserved
onsite.
An HLP is not required for this project because it is located within the approved South County MSCP area. As such,
take authorization has been granted for covered species including the coastal California gnatcatcher. Mitigation
is still required per the BMO.
2.0 INTRODUCTION, PROJECT DESCRIPTION, LOCATION, SETTING
The project site is located at 9046 Westhill Road within the community of Lakeside, in the County of San Diego
and the unincorporated lands within Metro Lakeside-Jamul. The proposed Project, within APN’s 385-023-19-00
and 385-023-20-00, includes the re-development of the existing graded pads, roadways and manufactured slopes
within the Project area (Figures 2 and 3). The project is a proposed residential subdivision of a 5.68-acre project
site into four (4) parcels.
The site is subject to the General Plan Regional Category Semi-Rural, Land Use Designation Semi-Rural Residential
(SR-1). Zoning for the site is Limited Agriculture (A70). The site is developed with an existing Single-Family
Residence which will be retained and coastal sage scrub habitat located adjacent to the northern Property line.
Access would be provided by private driveways connecting to a new private road which will connect to Westhill
Terrace.
Topography, Soils, Land Use
The project site occurs within a generally developed landscape, with residential development on all sides; there is
a section of Preserve Habitat to the west (Rattlesnake Mountain Preserve), and then more housing. As such, the
majority of the site is mildly topographically varied with the western portion of the site comprised of a
5
manufactured/altered slope and backyard area. Site elevation differs by approximately 60 feet across the site and
slopes downward from the west boundary (adjacent to the Rattlesnake Mountain Preserve) of the site east
towards the center of the properties.
Soils (USDA web soil survey, 2017) onsite are comprised of Vista Course sandy loam (15-30% slopes) on the
western 1/3 of the site consisting of the slope and Visalia sandy loam (5-9% slopes) on the balance of the site.
Onsite, the property is generally developed or disturbed with the historic grading and residential uses; surrounding
the perimeter of the Property are existing residential homes, Fuel Modification/Brush Management Zone
protecting the existing residences (on and offsite neighbors) and the Rattlesnake Mountain Preserve.
3.0 REGIONAL CONTEXT
The proposed project is within the unincorporated land within the Metro-Lakeside-Jamul segment of the South
County San Diego Multiple Species Conservation Program (MSCP) planning area. The property is not within a
proposed Pre-Approved Mitigation Area (PAMA). The site is in an area of existing residential development and
infrastructure improvements. The effected parcels are surrounded by residential development to the north, east
and south and the Rattlesnake Mountain Preserve to the west.
4.0 SURVEY METHODOLOGY
BLUE senior biologist, Michael Jefferson, conducted the surveys within the project area on and March 28th 2017.
The entire site, as well as a 100-foot buffer surrounding the Property, was surveyed on foot and habitat mapped
on a digital aerial of the Property (Figure 4).
Mapping was performed following the County of San Diego Report Format and Content Requirements, Biological
Resources (County 2010). Wildlife species were identified directly by sight or by vocalizations, and indirectly by
scat, tracks, or burrows. Field notes were maintained throughout the surveys and species of interest were
mapped. The primary focus of the survey was to document and map the size, location, and general quality of all
habitat types and the presence or potential presence of any sensitive resources onsite.
TABLE 1 Survey Details

Vegetation communities were assessed and mapped on a color aerial with topography flown in March 2015 (Google
earth). Animal species observed directly or detected from calls, tracks, scat, nests, or other sign were noted. All
plant species observed on-site were also noted, and plants that could not be identified in the field were identified
later using taxonomic keys.

Limitations to the compilation of a comprehensive faunal and floral checklist were few within the survey area –
most of which had been previously, legally, graded. The general quality of graded land and urbanized habitat
within the survey area is, as expected, of low quality. Surveys were completed at the optimal time and due to the
historic grading of the area as well as the ongoing use and maintenance it was determined that the existing site
conditions precluded the recommendation of additional surveys being recommended as a comprehensive
checklist was prepared.
Prior to conducting the biological survey, a thorough review of relevant maps, databases, and literature pertaining
to biological resources was performed. Recent aerial imagery (Google Earth 2017), topographic maps (USGS 2012),
soils maps (USDA 2017), and other maps of the project site and immediate vicinity were acquired and reviewed
to obtain updated information on the natural environmental setting. In addition, a query of sensitive species and
habitat databases was conducted, including the California Natural Diversity Database (CNDDB; CDFG 2012a), the
California Native Plant Society Electronic Inventory (CNPSEI; CNPS 2012), and the Consortium of California
Herbarium (Consortium 2012) applications, as well as a review of regional species lists produced by the USFWS
(USFWS 2012a) and CDFW (CDFW 2011, 2012a, CDFW 2012b, and 2012c).
The pre-survey investigation also included a verification of whether or not the project site falls within areas
designated as final or proposed USFWS Critical Habitat for federally threatened or endangered species (USFWS
2012b). No USFWS designated Critical Habitat is located onsite. Immediately offsite to the west is the Rattlesnake
Mountain Preserve and USFWS designated gnatcatcher critical habitat.
The complete list of sensitive species (CNDDB) and habitats that have been previously recorded within the vicinity
of the project site was compiled, and all recorded locations of species and other resources were mapped and
overlaid onto aerial imagery using Geographic Information Systems (GIS) software. The CNDDB list of sensitive
species included all database results for areas within 9 California USGS 7.5 minute topographic quadrangles.
Delineated boundaries of all features identified within the study area were recorded using a 1” =100’ aerial
photograph.
5.0 HABITATS/VEGETATION COMMUNITIES/WILDLIFE
The following discussion summarizes the existing and potentially present biological resources onsite and within
the project footprint, as determined from the completed general biological survey, sensitive species
presence/potential survey and the Resource Protection Ordinance.
Biological resources observed include three (3) habitat types. Habitats observed include: Disturbed Coastal Sage
Scrub (CSS), Disturbed habitat (graded, hydroseeded, avocado mowed) and Developed areas.
No Jurisdictional and/or County RPO waters/wetlands were observed onsite. No state, federally listed, or locally
identified Special Status plant or wildlife species were observed onsite.

5.1 Habitat/Vegetation Communities
Habitat descriptions are based on the County of San Diego Report Format and Content Requirements, Biological
Resources (County 2010) and Terrestrial Vegetation Communities in San Diego County based in Holland’s
Descriptions (Holland, 2010).
The habitat types observed include: Disturbed Coastal Sage Scrub, Disturbed Habitat and Developed Area. A
complete list of plant species observed onsite is included in Appendix A.
Coastal Sage Scrub (Holland Code 32000)
Coastal sage scrub is a native scrub-type community that is widespread throughout the lower elevations of
southern California. For the purposes of this assessment, coastal sage scrub has been defined to include elements
of Diegan coastal sage scrub (Holland 1986), coastal scrub, coyote brush series (CDFW 2008), and California
buckwheat series (Sawyer and Keeler-Wolf 2009) due to the potential variability of stands that exist within the
property. Coastal sage scrub vegetation consists of low-growing, drought-deciduous, perennial and evergreen
shrubs adapted to xeric sites supported by steep and gentle sloping topography with severely drained soils or
clays that release stored soil moisture slowly. This habitat may occur as a dense scrub-type community of
scattered shrubs, sub-shrubs, and herbs generally less than 3 feet tall and often developing considerable cover.
Typical stands of coastal sage scrub are dominated by the native shrub, California sagebrush (Artemisia
californica), with a sub-dominance of one or more native shrubs, and an herbaceous understory consisting of
native and non-native grasses and annual forbs. Species include California sagebrush, California buckwheat
(Eriogonum fasciculatum), black sage (Salvia mellifera), white sage (Salvia apiana), laurel sumac (Malosma
laurina), sticky monkeyflower (Mimulus auranticus), and California aster (Corethrogyne filaginifolia), among
others. This community is fire-adapted, with many constituent species being able to sprout new stems from
remnant crowns after a burn. In southern California, this community typically intergrades with coastal dunes scrub
and foredune habitats along the coast, and with grassland, chaparral, and oak woodland habitats at inland locales.
Onsite, the 0.16 acres of disturbed coastal sage scrub occurs on the north-western corner of the Property, adjacent
to the Rattlesnake Mountain Preserve. The habitat is dominated by sage (Artemisia Californica) and buckwheat
(Eriogonum fasciculatum) with mustard ssp. (Hirschfeldia incana) as the dominant understory interspersed
amongst the shrubs. The onsite disturbed CSS is considered Moderate Value and supports nesting or foraging
potential for the coastal California gnatcatcher (Polioptila californica californica). No CAGN or nests were observed
at the time of the survey.
Disturbed Habitat (Holland Code 11000)
Description: Characterized by predominantly non-native species introduced and established through human
action. These areas are not typically artificially irrigated, but receive water from precipitation or runoff.
Distribution: Throughout San Diego County especially in highly populated areas, coastal and riparian zones.
This designation is used for the majority of the site, totaling 4.96 acres, which was historically graded, cleared and
maintained for the existing on and offsite residential uses and brush management. The dominant species within
8
the Disturbed area is mustard ssp. (Hirschfeldia incana) or Erodium ssp. Also within this area is a grove of avocado
trees, compacted dirt roads and fencing.
Developed (Holland Code 12000)
Description: Areas that have been constructed upon or otherwise physically altered to an extent that native
vegetation is no longer supported. Developed land is characterized by permanent or semi-permanent structures,
pavement or hardscape, and landscaped areas that often require irrigation. Areas where no natural land is
evident due to a large amount of debris or other materials being placed upon it may also be considered
Urban/Developed (e.g., car recycling plant, quarry).
Characteristic Species: Unvegetated or landscaped with a variety of ornamental (usually non-native) plants.
This designation is used for the portion of the site, totaling 0.56 acres, that supports the existing house and roads.
TABLE 2 Vegetation Communities
Habitat Type Habitat Tier On-Site (Acres)
Coastal sage scrub II 0.16
Disturbed Habitat IV 4.96
Developed IV 0.56
Total 5.68
5.2 Wildlife
A total of 8 wildlife species were identified onsite. A complete list of wildlife species observed onsite is included
as Appendix B.
Invertebrates observed included harvester ants (Pogonomyrmex barbatus) observed on the south-western
corner of the Property. The reptile species observed onsite, within the Disturbed slopes was the western fence
lizard (Sceloporus occidentalis). Bird species observed included common raven (Corvus corax), mourning dove
(Zenaida macroura), scrub jay (Aphelocoma californica), and house finch (Carpodacus mexicanus). No mammals
were observed or detected onsite.
The property is generally un-developed but mechanically altered (graded and maintained) and surrounded by
moderate density development and not within or adjacent to an existing recognized habitat corridor.
Immediately to the west, the Property boundary is adjacent to the Rattlesnake Mountain Preserve. However, due
to the developed and disturbed nature of the onsite habitat, and lack of quality habitat, no animals, or sign of
animal movement through the property was observed. The area does not support a functioning corridor, linkage
or nursery site. As a result, no sensitive wildlife (raptors, owls, mammals, etc.) are expected to occur onsite.
6.0 SPECIAL STATUS SPECIES and SENSITIVE RESOURCES
Sensitive or special interest plant and wildlife species and habitats are those which are considered rare,
threatened, or endangered within the state or region by local, state, or federal resource conservation agencies.
9
Sensitive habitats, as identified by these same groups, are those which generally support plant or wildlife species
considered sensitive by these resource protection agencies or groups. Sensitive species and habitats are so called
because of their limited distribution, restricted habitat requirements, particular susceptibility to human
disturbance, degradation due to development or invasion by non- native species, or a combination of all of these
factors.
In addition to BMO, RPO and the County of San Diego Report Format and Content Requirements, Biological
Resources (County 2010), the following were used in the determination of sensitive biological resources: U.S. Fish
and Wildlife Service (USFWS); and California Department of Fish and Wildlife (CDFW). An explanation of the
sensitivity codes used in this report is included in Appendix E.
6.1 Sensitive Habitats
Disturbed Coastal Sage Scrub was observed onsite and is considered a sensitive habitat. Even if in a disturbed
condition, Coastal Sage Scrub habitat is considered sensitive by the resources agencies since it may still serve as
habitat for wildlife.
6.2 Sensitive Plants
Sensitive or special interest plant species are those which are considered rare, threatened, or endangered within
the state or region by local, state, or federal resource conservation agencies. Sensitive plant species are so called
because of their limited distribution, restricted habitat requirements, or of particular susceptibility to human
disturbance, or a combination of these factors. Sources used for the determination of sensitive plant species
include: CDFW (2015), CNPS (2013), and CNDDB (2015).
No sensitive plant species were observed onsite and due to the disturbed and developed nature of the Property,
none are expected to occur.
Sensitive Plant Species with the Potential to Occur Onsite
Thirty-one sensitive plants were assessed for the potential to occur onsite and are discussed in Appendix C. In
summary, of the thirty-one sensitive plants assessed, none has greater than a low potential to occur onsite due
to lack of observations in the area and onsite, a lack of appropriate soils, hydrologic conditions and the disturbed
and developed nature of the site.
6.3 Sensitive Animals
Sensitive or special interest wildlife species and habitats are those which are considered rare, threatened, or
endangered within the state or region by local, state, or federal resource conservation agencies. Sensitive
species are so called because of their limited distribution, restricted habitat requirements, or particular
susceptibility to human disturbance, or a combination of these factors. Sources used for the determination of
sensitive biological resources include: USFWS, CDFW. Additional species receive federal protection under the
Bald Eagle Protection Act and the Migratory Bird Treaty Act and Convention for the Protection of Migratory Birds
and Animals.
10
The CDFW also lists species as threatened or endangered, or candidates for listing as threatened or endangered.
Lower sensitivity animals may be listed as “species of special concern” (CDFW). The CDFW further classifies some
species under the following categories: “fully protected,” “protected furbearer,” “harvest species,” “protected
amphibian,” and “protected reptile.” The designation “protected” indicates that a species may not be taken or
possessed except under special permit from the CDFW; “fully protected” indicates that a species can be taken
only for scientific purposes. The designation “harvest species” indicates that take of the species is controlled by
the state government.
6.3.1 Sensitive Wildlife Observed
No sensitive wildlife species were observed/detected onsite. Due to the presence of disturbed coastal sage scrub,
there is a moderate chance for the coastal California gnatcatcher to occur onsite.
6.3.2 Sensitive Wildlife Species with the Potential to Occur Onsite (not observed)
Numerous sensitive species have been historically observed in the general area, specifically the California
gnatcatcher which has been observed offsite to the west within the Rattlesnake Mountain Preserve. A complete
list and explanation as to the potential occurrence of all Sensitive Wildlife with the Potential to Occur is described
in Appendix D.
Coastal California gnatcatcher (Polioptila californica californica) is a USFWS Threatened species, a State Species
of Special Concern, and a County Group 1 species. The California gnatcatcher is closely associated with coastal
sage scrub vegetation, particularly Diegan coastal sage scrub occurring on gentle slopes within the maritime and
coastal climate zones. In San Diego and Orange counties, the California gnatcatcher occurs most commonly in
coastal sage scrub vegetation with high proportions of Artemisia californica and Eriogonum fasciculatum and less
commonly in sub-associations dominated by Salvia mellifera or Rhus integrifolia.
The property supports a small pocket of disturbed coastal sage scrub in the NW corner that is potentially suitable
habitat for the coastal California gnatcatcher onsite; none were observed onsite during the general surveys. While
the CSS onsite is in a disturbed condition, there is a moderate potential for the species to occur on-site due to the
presence of appropriate habitat and historical observations in the adjacent Preserve.
Additional species with a moderate potential to occur include:
San Diego Horned Lizard (Phrynosoma coronatum blainvillii)
LISTING: USFWS - Federal Special Concern Species
CDFG - California Species of Special Concern
DISTRIBUTION: California and Baja California, Mexico.
HABITAT: Open chaparral, sage scrub, pine/oak woodlands, grasslands, and along
washes.
STATUS: Declining, primarily due to habitat destruction and habitat degradation.
Status as an object for pet collection has also attributed to its decline.
11
ONSITE STATUS: Not observed. Harvester ants observed onsite, adjacent to quality habitat; moderate
potential to occur onsite.
Belding's Orange-throated Whiptail (Cnemidophorus hyperythrus beldingi)
LISTING: USFWS - Federal Special Concern Species
CDFG- California Species of Special Concern
DISTRIBUTION: Limited; found from southern Orange, western Riverside, and San Diego
counties south to southern Baja California, Mexico.
HABITAT: Open woodlands, sage scrub, chaparral, and along the edges of riparian
zones and washes.
STATUS: This species is still relatively common in areas where good habitat occurs;
however, vast areas of former habitat in the coastal lowlands have been
converted to urban and agricultural development.
ONSITE STATUS: Not observed. Harvester ants observed onsite, adjacent to quality habitat; moderate
potential to occur onsite.
Southern California Rufous-crowned Sparrow (Aimophila ruficeps canescens)
LISTING: USFWS - Federal Special Concern Species
CDFG -California Species of Special Concern
DISTRIBUTION: Coastal southern California from Santa Barbara County south into
northern Baja California, Mexico.
HABITAT: Sparse, low scrub, often mixed with grasses on rocky slopes. California
Sagebrush (Artemisia californica) is often present.
STATUS: Uncommon to fairly common but localized resident. Listing is based on
concern that this species is among the most sensitive to habitat fragmentation
ONSITE STATUS: Not observed. Adjacent to quality habitat; moderate potential to occur onsite.
6.3.3 Raptors/Owls
The survey area supports a mature ornamental and avocado trees. Mature trees can support barn owls and
raptor nesting. Raptors are large predatory or scavenger birds that typically require tall trees for perching and
nesting associated with adjacent open grasslands to forage. Due to declining habitat and the associated declining
numbers of these species on the whole, many raptor species have been designated as California Species of Special
Concern by the CDFW. These species are protected, especially during their critical nesting and wintering stages.
Raptors are protected under the CDFW California Raptor Protection Act (Title 14, Section 670). No raptors or
barn owls, roosts, or sign such as pellets, were observed onsite.
In addition, the site has a low potential for raptor foraging. This is because the property is surrounded by moderate
density residential development, is generally sloped, un-developed and mechanically altered (graded and
maintained); supporting maintained disturbed habitat that lacked indicators of mammals (burrows); the area of
fallow/open land is small, approximately 5 acres on/offsite. As a result, the area is not suitable/utilized as foraging
habitat for raptors/owls.
12
7.0 JURISDICTIONAL WETLANDS and WATERWAYS
A formal preliminary protocol ACOE wetland delineation was not completed. No potentially jurisdictional/RPO
wetlands/waters were observed onsite.
8.0 OTHER UNIQUE FEATURES/RESOURCES
Wildlife Corridors
Development within San Diego County has reduced the total available open space for wildlife populations, and in
some instances, created isolated "islands" of habitat. In general, corridors and linkages are smaller constrained
areas of habitat that connect larger areas of habitat which are otherwise separated by rugged terrain, changes in
vegetation, or urban development. This allows for an exchange of gene pool between wildlife populations, which
increases the genetic viability of otherwise isolated populations. Wildlife corridors are especially important for
species with large habitat ranges or seasonal migrations. A corridor is a specific route that is used for the
movement and migration of species, and may be different from a linkage in that it represents a smaller or
narrower avenue for movement. A linkage is an area of land that supports or contributes to the long-term
movement of wildlife and genetic exchange by providing live-in habitat that connects to other habitat areas. Many
linkages occur as stepping-stone linkages that are comprised of fragmented archipelago arrangement of habitat
over a linear distance. In either case, corridors and linkages will be comprised of land features which accommodate
the movement of all sizes of wildlife, including large animals on a regional scale. Their contributing areas will
support adequate vegetation cover, providing visual continuity and long lines of sight, so as to encourage the use
of the corridor by all types of wildlife. In San Diego County, important corridors/linkages have been identified on
the local and regional scale in establishing a connection between the northern and southern regional populations
of the coastal California gnatcatcher.
The property is un-developed but mechanically altered (graded and maintained) and surrounded by moderate
density development and not within or adjacent to an existing recognized habitat corridor. Immediately to the
west, the Property boundary is adjacent to the Rattlesnake Mountain Preserve. However, due to the developed
and disturbed nature of the onsite habitat, and lack of quality habitat, no animals, or sign of animal movement
through the property was observed. The area does not support a functioning corridor or linkage.
9.0 REGULATORY REQUIREMENTS
This section addresses potential direct, indirect, and cumulative impacts to biological resources that would result
from implementation of the proposed project, and provides analyses of significance for each potential impact.
Applicable Resource Conservation Plans and Ordinances
In San Diego County, guidelines and regulations have been adopted which define and provide protection to certain
types of sensitive biological resources. The San Diego MSCP Plan for the southwestern portion of San Diego County
was approved in 1997 and covers 85 species. The City of San Diego, portions of the unincorporated County and
ten additional city jurisdictions make up the San Diego MSCP Plan area. The County Subarea Plan was adopted by
the Board of Supervisors in March 1998.
In addition, the following regulations are applicable to the Project, as follows:
13
Migratory Bird Treaty Act
The Migratory Bird Treaty Act (MBTA) of 1918 (16 U.S. Code 703-711) implements an international treaty for the
conservation and management of bird species that may migrate through more than one country. The MBTA
protects all common wild birds found in the U.S. except the house sparrow, starling, feral pigeon, and resident
game birds such as pheasant, grouse, quail, and wild turkey. Enforced in the U.S. by the USFWS, the MBTA makes
it unlawful to take, possess, buy, sell, purchase, or barter any migratory bird listed in Code of Federal Regulations
Title 50, Part 10, including feathers or other parts, nests, eggs, or products, except as allowed by implementing
regulations. Disturbance that causes nest abandonment and/or loss of reproductive effort (e.g., killing or
abandonment of eggs or young) may be considered a “take” and is potentially punishable by fines and/or
imprisonment. In 1972, the MBTA was amended to include protection for migratory birds of prey (raptors).
Generally, applicants who obtain a federal ESA Section 10(a) permit simultaneously receive a three-year MBTA
permit for ESA-listed migratory birds.
Biological Mitigation Ordinance
The Biological Mitigation Ordinance (BMO) is the implementing ordinance for the Multiple Species Conservation
Program County Subarea Plan. Compliance with this ordinance allows the County to issue Incidental Take Permits
for projects that impact sensitive habitats.
Resource Protection Ordinance (RPO)
The purpose of the RPO is to protect sensitive resources and prevent their degradation and loss. The sensitive
resources protected by the RPO include wetlands, wetland buffer areas, and sensitive habitat lands, which are
defined as follows:
"Wetland" areas include lands which are transitional between terrestrial and aquatic systems where the water
table is usually at or near the surface or where the land is covered by water. Lands having one or more of the
following attributes are “wetlands:”
(a). At least periodically, the land supports a predominance of hydrophytes
(plants whose habitat is water or very wet places);
(b). The substratum is predominantly undrained hydric soil; or
(c). An ephemeral or perennial stream is present, whose substratum is predominately non-soil and such lands
contribute substantially to the biological functions or values of wetlands in the drainage system.
"Wetland buffer" areas include lands which provide a buffer area of an appropriate size to protect the
environmental and functional habitat values of the wetland, or which are integrally important in supporting the
full range of the wetland and adjacent upland biological community.
"Sensitive habitat lands" include those which support unique vegetation communities, or the habitats of rare or
endangered species or sub-species of animals or plants, including the area which is necessary to support a viable
population of any of these species in perpetuity, or which is critical to the proper functioning of a balanced natural
ecosystem or which serves as a functioning corridor. (County, 2012)
14
Direct Impacts are immediate impacts resulting from the permanent or temporary removal of habitat as required
for the Project.
Indirect Impacts result from changes in land use adjacent to natural habitat and primarily result from adverse
“edge effects;” either short-term indirect impacts related to construction or long-term, chronic indirect impacts
associated with urban development. During construction of the project, short-term indirect impacts include dust
and noise which could temporarily disrupt habitat and species vitality or construction related soil erosion and run-
off. Long-term indirect impacts may include intrusions by humans and domestic pets, noise, lighting, invasion by
exotic plant and wildlife species, use of toxic chemicals (fertilizers, pesticides, herbicides, and other hazardous
materials), soil erosion, litter, fire, and hydrological changes (e.g., groundwater level and quality).
Cumulative Impacts refer to incremental individual environmental effects of two or more projects when
considered together. These impacts taken individually may be minor, but collectively significant as they occur over
a period.
Thresholds of Significance refer to the evaluation of whether an impact to a biological resource is significant must
consider both the resource itself and the role of that resource in a regional context. Substantial impacts
are those that contribute to, or result in, permanent loss of an important resource, such as a population of a
rare plant or animal. Impacts may be important locally because they result in an adverse alteration of existing
site conditions, but considered not significant because they do not contribute substantially to the permanent loss
of that resource regionally. The severity of an impact is the primary determinant of whether that impact can be
mitigated to a level below significant. Generally, there are three levels of adverse impacts associated with
biological resources: significant, locally important, and not significant. The determination of significance follows
the County of San Diego Guidelines For Determining Significance for Biological Resources (2010).
10.0 SIGNIFICANCE of PROJECT IMPACTS
Impacts to biological resources are assessed by County staff through the CEQA review process, and through review
of the project’s consistency with the County MSCP Subarea Plan requirements and as described in the County of
San Diego Guidelines for Determining Significance and Report Format and Content Requirements, Biological
Resources (County of San Diego, 2010).
10.1 Avoidance and Minimization
The proposed project has been designed to avoid impacts to biological resources to minimize significant direct,
indirect and cumulative impacts. The proposed development is clustered within the existing disturbed and
developed portion of the site (Figures 6).
No direct Project related impacts (grading/Brush Management Zone) to the CSS are proposed. This sensitive
habitat will be placed in a biological open space easement (adjacent to the existing Open Space Preserve). As a
result, the is no impact to the CSS will occur. The biological open space easement will be protected from future
fire clearing through the dedication of a 100-foot wide limited building zone easement.
15
10.2 Proposed Project Impacts
Of the existing 5.68-acre Property, a total of 2.91 acres of area/habitat is proposed to be impacted by grading
and direct project impacts (Table 5, Figures 6 and 7) for the development of the Property
All impacts are within the disturbed/developed portion of the Property; no potentially significant impacts are
proposed. Because the 0.16 acres of onsite CSS are to be preserved within a biological open space easement, no
CSS impacts are proposed.
10.3 Significance of Impacts
Generally, there are three levels of adverse impacts associated with biological resources: significant, less than
significant, and no impact. These levels of impacts were applied to the project site and are used below in the
discussion of specific potential impacts.
10.3.1 Sensitive Plant Community Impacts
No potentially significant impacts to the onsite CSS (the only sensitive habitat onsite) are proposed. A biological
open space easement and 100-foot wide limited building zone easement are required of the proposed project.
The 100-foot-wide LBZ easement, as measured from the outer edge of the created OS, has been incorporated
into the project to protect the created onsite OS (Figure 6). The 0.16 acres of onsite CSS will be preserved within
the biological open space easement (totaling 0.26 acres).

Total 5.68 5.52 0.26 0.0 *On and Off-site grading
10.3.2 Sensitive Plant Species Impacts
No sensitive plant species were documented or are expected to occur onsite. No potentially significant
impacts to sensitive plant species are expected to occur.
10.3.3 Sensitive Wildlife Species Impacts
No sensitive wildlife species were documented onsite. No grading or Project related impacts are proposed within
the onsite CSS. The site supports no existing/historical bird/raptor nests but does support potential owl/raptor
nesting habitat (disturbed habitat and mature ornamental trees). These potential impacts would be mitigated to
less than significant levels with the implementation of mitigation measure(s):
16
No mammal, burrows, or bird activity/presence was observed. Because barn owls and raptors have been
historically observed in the grading/impact area and there is nesting/roosting potential in onsite trees as well as
large open areas onsite, owl/raptor nesting within this Property has the potential to occur.
As previously described, the property is surrounded by moderate density residential development, is generally
sloped, un-developed and mechanically altered (graded and maintained); supporting maintained disturbed
habitat that lacked indicators of mammals (burrows). The area of fallow/open land is small, approximately 5 acres
on/offsite. As a result, the loss of the disturbed habitat that could potentially be utilized for foraging birds is less
than significant because no foraging activity was observed and the area is not suitable/utilized as foraging habitat.
No additional mitigation for loss of foraging habitat is recommended at this time.
As potentially appropriate raptor nesting sites have been observed onsite, preventative mitigation measures to
preclude direct and/or indirect impacts violating the Migratory Bird Treaty Act (MBTA) shall be implemented.
Potential nesting sites are defined as large trees, and/or man-made towers/poles etc. Preventative mitigation
(pre-construction surveys) are described (Proposed Mitigation, below).
No potentially significant impacts to Sensitive Wildlife species are expected to occur with the implementation of
the proposed mitigation measure(s).
11.0 PROPOSED MITIGATION
Under CEQA, mitigation is required for all significant biological impacts (e.g. impacts within highly constrained
areas). In addition, the CDFW 1600, RWQCB 401 Certificate and the ACOE 404 permit process generally require
mitigation for the loss of wetland resources. The following mitigation measures are recommendations to locally
important biological impacts. Although mitigation measures are not often required for locally important impacts,
local jurisdictions often implement these measures to minimize cumulative impacts within the region.
Per Appendix G of the State CEQA guidelines, the proposed project would have a potentially significant
impact to onsite biological resources if it would:
• Have a substantial adverse effect, either directly or through habitat modifications, on any species
identified as a candidate, sensitive, or special-status species in local or regional plans, policies, or
regulations, or by the California Department of Fish and Wildlife or U.S. Fish and Wildlife Service.
• Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified
in local or regional plans, policies, regulations, or by the California Department of Fish and Wildlife or U.S.
Fish and Wildlife Service.
• 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.
• Interfere substantially with the movement of any native resident or migratory fish or wildlife species or
with established native resident or migratory wildlife corridors or impede the use of native wildlife nursery
sites.
17
• Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation
policy or ordinance.
• Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation
Plan, or other approved local, regional, or state habitat conservation plan.
11.1 Direct Impacts - Mitigation
Direct impacts mean those impacts that cause a permanent alteration of the physical, chemical or biological
properties of the surface or of the functions and values of a habitat.
In order to prevent potentially significant direct impacts to CSS, dedication of a biological open space easement
and adjacent 100-foot wide limited building zone easement are proposed. Open space signage will be placed at
the edge of the proposed easement.
To prevent potential significant impacts to breeding birds/raptors, if brushing, clearing and/or grading is proposed
during the bird/raptor breeding season (February 1 – August 31) then a pre-construction survey for active nests
shall be performed no more than three days prior to the initiation of construction. If an active nest is identified
onsite, then grading shall be postponed until the nest is no longer active.
11.2 Indirect Impacts
Temporary impacts mean those impacts that do not cause a permanent alteration of the physical, chemical or
biological properties of the surface or of the functions and values of a habitat. Temporary impacts include
activities in which the ground is restored to its preconstruction contours and elevations, such that previous
functions and values are restored.
No potentially indirect impacts are proposed or expected to occur. In order to protect sensitive biological
resources within the proposed biological open space easement from vegetation management requirements,
introduction of exotic pest plants, and increased light and noise, pursuant to CEQA, a Limited Building Zone (LBZ)
easement shall be created. This 100-foot-deep LBZ easement, as measured from the outer edge of the created
OS, has been incorporated into the project to protect the created onsite OS (Figure 6).
12.0 CUMULATIVE IMPACTS
The proposed project will not contribute to the cumulative loss of Coastal Sage Scrub (CSS) within the local
community of Lakeside and unincorporated San Diego County. The Project will preserve and protect all onsite CSS.
The Property does not support an identified wildlife corridor and the steep slopes and ridgeline will remain
undeveloped allowing the existing wildlife movement to continue unimpeded. The Project creates a biologically-
viable preserve design that will maintain and contribute toward a future preserve system in this portion of the
County. The project includes a dedicated Limited Building Zone (LBZ) Easement onsite to prohibit construction of
habitable structures that would require fire-clearing into the onsite preserve.
This Project has a proposed positive contribution to the Preserve. The project site avoids all direct impacts to CSS.
Through these proposed design and mitigation measures, the project will have no cumulatively impact to
biological resources.
