SUBJECT: Biological Technical Report for APN #206-180-40
Polzin Lot
Carlsbad, CA 92008
This letter report summarizes the results of a site investigation by Planning Systems' biologists
regarding the existing vegetation occurring on the Polzin lot and Adams Street frontage, a 0.34 acre
single family zoned parcel, APN #206-180-40, located on the north side of Adams Street in Carlsbad,
California. The investigation also includes the offsite 0.01 acre right-of-way (ROW) frontage owned
by the City of Carlsbad. The property presently is vacant and is planned for improvement with a
single family residence and associated driveway, landscaping and associated improvements. This
report identifies vegetation communities and plant species existing on-site, quantifies proposed
project related impacts, and addresses mitigation measures, if necessary to reduce potential project
impacts to biological habitats to a level of insignificance.
1.0 Executive Summary
The Polzin property is located on the northeast side of Adams Street in an urbanized area of the City
of Carlsbad. The site is located approximately 450 feet northeast of Agua Hedionda Lagoon. The
property is located within the City of Carlsbad Subarea Plan Area of the North County Multiple
Habitat Conservation Program (MHCP). The City of Carlsbad manages compliance with the MHC
through their approved Habitat Management Plan for Natural Communities (HMP). The site is not
located within an existing or proposed hardline preserve area or within a standards area of the HMP.
The Polzin property and ROW frontage has been highly disturbed and regularly maintained over the
years. Existing on-site plant associations include only two land cover types; Non-Native Grassland
(NNG) and Disturbed Habitat (DH). These vegetation communities are not considered sensitive
habitats. The project will impact a total of0.15 acres ofNNG and a total of 0.20 acres of DH. NNG
occurs in locations on the site where Hottentot Fig (Carpobrotus edulis) is not present to suppress
weed growth. Species present include Brome Grass (Bromus sp.), Tumbleweed (Salsola tragus),
Sahara Mustard (Brassica tournefortii) and African Fountain Grass (Cenchrus setaceus). The onsite
DH land cover are areas that have been physically disturbed (by previous legal human activity) and
are no longer recognizable as a native or naturalized vegetation association, but continues to retain a
soil substrate. No special status plant species were observed to occur on the property.
Notwithstanding that the two land cover types are not considered sensitive habitats, the vegetation is
considered of value to fauna which utilize the vegetation area as foraging habitat, and thus mitigation
for impacts to NNG and DH is required in order to reduce the impacts to a level of insignificance.
The City HMP provides that these impacts may be mitigated for through payment of an In-Lieu fee
based on a City approved fee schedule. Thus the project will be required to pay this HMP In-Lieu
mitigation fee in order to reduce the impacts to a less than significant level. This requirement is
referenced in Mitigation Measure BI0-1.

The project would not directly impact any federal or state threatened or endangered plant or wildlife
species. However the project has the potential to result in significant indirect impacts to common
and/or sensitive nesting birds potentially occurring within the Diegan Coastal Sage Scrub (DCSS)
located offsite and across Adams Street to the southwest. These indirect impacts could result from
construction noise levels if construction occurred during the nesting season. These impacts will be
reduced to a level of insignificance with the implementation of Mitigation Measure BIO-2, requiring
biological monitoring of nesting season construction.
No wetlands, riparian habitat or other habitat considered jurisdictional by the U.S. Army Corps of
Engineers, California Department of Fish and Wildlife or the Regional Water Quality Control Board
are identified on the property. The project will not negatively affect existing or proposed wildlife
corridors.
In light of these factors; implementation of the proposed project, including project compliance with
Mitigation Measures BIO-1 and BIO-2 referenced in this report, will result in all potential biological
impacts being reduced to a level of less than significant. No other mitigation is required.
2.0 Setting
While the Polzin property is geographically oriented at an angle off of due north-south longitude; for
purposes of this report the lot is assumed to face south onto Adams Street frontage. The parcel is
generally rectangular in shape, 0.34 acre in size (total 0.35 acres including Adams Street frontage
ROW and dedication), and is located on the north side of Adams Street, between Hoover Street and
Highland Drive, in Carlsbad, CA. (Figure I; Location Map). The parcel is located in an urbanized
setting, surrounded on the north, east and west by single family lots/homes. Across Adams Street to
the south, vacant land containing natural DCSS habitat exists with Agua Hedionda Lagoon further to
the south and beyond.
The approximate center of the property is 33.146925 degrees North latitude and 117.328781 degrees
West longitude on the U.S. Geological Survey 7.5-minute series topographic San Luis Rey quadrangle
map. See Figure 2; USGS Map. The Property is approximately 0.6 miles inland from the Pacific
Ocean, and 450 feet north of the Agua Hedionda Lagoon within City of Carlsbad Local Facilities
Management Plan Zone 1.
The property is considered foothill terrain, sloping from a high point of 127 feet msl at the northern
property line, to a low point of 92 feet msl at the southwesterly corner of the lot. Drainage across the
site is generally characterized as sheet flow. The site is not listed in the National Wetland Inventory.
The soils report for the property indicates that the site contains fill/weathered material to a depth of 3
to 4 feet, with sandstone underlying the fill/weathered material. The sandstone consists of dense to
very dense, slightly silty sandstone. No groundwater was encountered by the geologists during the
soils test pit analyses. No structures exist on the property.
3.0 Methodology
An initial investigation of biological history through a review of pertinent scientific literature was
undertaken to assess a baseline from which to inventory the biological resources potentially occurring
in the area. Federal register listing, protocols, and species data provided by the U.S. Fish and Wildlife
Service (USFWS) were reviewed in conjunction with anticipated federally listed species potentially
occurring within the project site.

Resources reviewed to assess the history of the property in and around the area include; the California
Natural Diversity Database (CNDDB), the California Department of Fish and Wildlife (CDFW)
Natural Heritage database, the San Diego Association of Governments (SAND AG) database and the
San Diego Natural History Museum.
A biological field survey of the Polzin property was also conducted. The survey fieldwork was
conducted by biologist Greg Evans on November 14, 2016. Survey conditions were good,
approximately 72 degrees air temperature, clear skies with a light breeze. Vegetation was mapped in
the field directly onto a 200-scale (1 inch= 200 feet) false-color digital orthographic map of the
property (Google Earth 2016). A Trimble R2 GNSS handheld sub-meter receiver was available but
determined not to be necessary. These boundaries and locations were digitized using an aerial
photograph and AutoCAD software. The entire site was traversed on foot. All plant species were
recorded. Vegetation community classifications used in this report follow Holland (1986) and
Oberbauer et al. (2008).
Animals identified during the field survey were identified by sight, call, tracks or scat. In addition to
species actually detected, expected use of the site by other wildlife was derived from the analysis of
habitats on the site. A resulting list of all plant and animal species observed on the property is
provided in Appendix A to this report.
4.0 Survey Limitations
Plant species observed on-site were identified and are listed in Appendix A. Some additional forbs
and annuals may be present but are not in a vegetative phase in November, and therefore not available
for observation. Some annuals observed are also not listed because they were so desiccated that
identification is uncertain. Rare plants that could be identified during the fall were sought. Species
typically found during spring focused surveys were not sought during November. The property has
been so regularly-maintained that Spring-blooming rare plants are not anticipated. Project mapping
has been restricted to areas within the properly lines, and to the Adams Street right-of-way south of
the parcel.
5.0 Applicable Regulatory Authority
Native upland vegetation along coastal southern California can possess unique ecological functions
and values, and in many cases are protected from human-induced destruction or degradation by a state
and local statutes. The regulatory land use documents applicable to the subject area are identified
below.
5 .1 California Coastal Zone
The project site is located within the Mello II Local Coastal Program segment of the California
Coastal Zone. The Mello II segment Land Use and Implementation documents have been certified by
the California Coastal Commission and thus the City of Carlsbad possesses land use permitting
authority for coastal development permits in this segment. The property is located outside of the
Coastal Commission appeal area. The Mello II documents identify the subject property as appropriate
for a single family home. This would include the residence structure, driveway, decks, patio, and
landscaping and accessory single family uses. Thus the proposed single family home and its
associated uses are permitted land uses per the Local Coastal Program.

5.2 City of Carlsbad Habitat Management Plan
The Carlsbad HMP provides policy regulation for vegetation resources and botanical land cover within
the City of Carlsbad. The HMP was adopted by the City in December 1999, and the final approvals
from USFWS and CDFW, including implementing agreement and terms and conditions, were granted
in November 2004. The purpose of the Carlsbad HMP is to guide the design, management, monitoring
and public use of a habitat preserve system throughout the city boundaries of the City of Carlsbad.
The Carlsbad HMP calls for 6,478 acres of natural habitat to be preserved within the City as well as
the protection of an additional 308 acres of habitat outside the City. The HMP identifies core
candidate preserve areas, linkages, and special resource areas which are intended to form the
background pattern of protected open spaces throughout the City. Within the Core and Linkage Areas,
the HMP requires that adequate open space preserve patterns be established through the protection of
hardline preserve areas. Within the context of this HMP, hardlines for this area of the City of Carlsbad
have been approved by the USFWS, CDFW and the City. These hardlines demarcate the limits of
development from the limits of habitat preserve.
Per the HMP, the subject property is located wholly within the area identified as developable. The
property is not located within or immediately adjacent to an existing or proposed Hardline Preserve
Area, a Focus Planning Area or a linkage or a Special Resource Area. The property is regulated by a
special set of Coastal Zone conservation standards articulated in Section D.7, Standards 7-1 through 7-
12.
While the property is also not located within a hardline or an identified HMP standards area, property
to the south, across Adams Street, is recognized in the HMP as a standards area. As a result, potential
edge effects and potential adjacency issues to sensitive habitats within this standards area are
addressed in this report.
6.0 Vegetation Resources
As indicated, a field plant survey of the subject property has been conducted. This survey concludes
that the vast majority of the property has been disturbed and regularly maintained and that two land
cover types (NNG and DH) occur and have been mapped on the Polzin property (See Figure 3;
Existing Vegetation Resources). A total of 20 species of vegetation were recorded on the property.
Appendix A includes a cumulative list of these plant species. These vegetation communities and plant
status are discussed in the following sections.
6.1 Non-Native Grassland (Code 42200) (0.15 acre)
Non-native Grassland consists of a dense to sparse cover of non-native, low-growing annual grasses
with flowering culms. Annual forbs are typically the dominant species. Germination occurs with the
onset of the rains in late fall. Growth, flowering and seed-set occurs from winter through spring.
NNG plants are typically dead through the dry summer-fall season, persisting only as seeds. Onsite,
the dominant NNG species are Red Brome (bromus rubens), Slender wild oat (Avena barbata),
Ripcut grass (Bromus diandrus) and African fountain grass (Cenchrus setaceus).
Non-Native Grassland is considered a non-sensitive vegetation community, although it does possess
biological value based on its importance as a foraging area for birds.

6.2 Disturbed Habitat (Code 11300) (0.20 acres)
Land cover that are designated "Disturbed Habitat" are areas that have been physically disturbed (by
previous legal human activity) and are no longer recognizable as a native or naturalized vegetation
association, but continues to retain a soil substrate. Typically vegetation in these areas is nearly
exclusively composed of non-native plant species such as ornamentals or ruderal exotic species that
take advantage of disturbance, or shows signs of past or present human activities that removes any
capability of providing viable natural habitat for uses other than dispersal. Examples of disturbed land
include areas that have been graded, repeatedly cleared for fuel management purposes and/or
experienced repeated use that prevents natural revegetation. Much of the Polzin property has been
regularly maintained to this condition. Onsite, Hottentot Fig (Carpobrotus edulis) has established
over most of the DH area. Other on-site species associated with this land cover include Castor bean
(Ricinus communis.), Spurge (Euphorbia SP) and Prickly lettuce (Lactuca serriola).
Disturbed Habitat is considered a non-sensitive vegetation community.
6.3 Summary of Vegetation Resources
A summary table of the existing vegetation resources on the property is provided in Table 1.

TOTAL 0.34 0.01 0.35
6.4 Special Status Plant Species
Special-status plant species considered in this report are those that are; (a) listed by federal and/or state
agencies, proposed for listing as threatened or endangered, or listed as candidate species; or (b) listed
as proposed for coverage in the Carlsbad HMP. The potential for special-status plant species to occur
on site was evaluated based on the elevation, soils, vegetation communities, and level of disturbance of
the site, as well as their status and distribution in the vicinity of the project area.
No federally listed or state listed plant species were detected or are expected to occur onsite due to the
marginal habitat quality, soils and disturbed condition. Likewise, none of the twenty-six (26) plant
species proposed for coverage under the HMP were identified.

7.0 Jurisdictional Aquatic Resources
The subject property does not contain any freshwater ponds, riparian hydrology or wetlands.
8.0 Wildlife
The Polzin property is not located within or adjacent to a USFWS designated critical habitat for any
federally listed species. The project site could provide occasional nesting or foraging area for
protected reptiles such as the Orange-throated whiptail (Aspidoscelis hyperythra beldingi), or birds
such as the Southern California rufous-crowned sparrow (Aimophila ruficeps), the Northern harrier
(Circus cyaneus), the Cooper's hawk (Accipter cooperii) and/or the White-tailed kite (Elanus
leucurus). While the Coastal California gnatcatcher (Polioptila californica californica) has been
documented off site to the south of the property, this species is not expected to breed or forage on the
Polzin property based on a lack of suitable habitat. Due to the severely limited amount of native
vegetation on the site, no substantive nesting sites or habitat for listed animal species are expected to
inhabit the subject property.
An animal survey was conducted in conjunction with the vegetation field work on November 14,
2016. The only invertebrate observed was the Cabbage White butterfly (Pieris rapae). No reptiles or
amphibians were observed. Evidence (burrows) of California ground squirrel (Otospermophilus
beecheyi) and scat of Brush rabbit (Sylvilagus bachmani) was observed on the property. Birds
observed within and around the area are the Western scrub jay (Aphelocoma coerulescens), Anna's
Hummingbird (Archilochus anna), Common crow (Corvus brachyrhynchos), Western Kingbird
(Tyranus verticalis) and Song sparrow (Melospiza melodia). Red-tailed hawk (Buteo jamaicensis)
was observed offsite foraging near the Agua Hedionda Lagoon shoreline.
9.0 Wildlife Movement Corridors
The City of Carlsbad HMP addresses potential impacts to native and sensitive species and habitats
while providing mitigation options in the form of conserved lands that satisfy the habitat-protection
requirements of the PESA and CESA. The HMP provides for open space connectivity that is
conducive to animal movement, allowing animals to access significant areas for foraging, hunting and
water sources. In addition, these protected habitat corridors allow the dispersal of individuals away
from high human population areas and facilitate the exchange of genetic traits between populations.
Thus the HMP preserve is a network of large blocks of open spaces with interconnecting linkages
which serve to benefit the animals which live and utilize these areas.
The subject property is not located within any Carlsbad HMP designated Focus Planning Areas
(FPA's), Linkages, or Special Resource Areas. However, the parcel is approximately 400 feet north
of Core Area #4, as shown on Figure 4 of the HMP. Core Area 4 includes critical upland and wetland
communities and several populations of sensitive plant and animal species. The project site is
detached from this FP A by single family designated lots and the Adams Street public roadway. The
proposed project site is identified as a future development area on Figure 17 of the HMP.
The project site is located within the Mello II Segment of the Carlsbad Local Coastal Program (LCP),
with the principal objective of this plan including protection of coastal waters and associated
tributaries. The City of Carlsbad is the permitting authority within this LCP area.

10.0 Evaluation of Project Impacts
The environmental impacts relative to biological resources are assessed using impact significance
criteria which mirror the policy statement contained in the California Environmental Quality Act
(CEQA) at Section 21001(c) of the California Public Resources Code. This section is summarized in
the following section.
10 .1 Thresholds of Significance
Pursuant to the requirements of the State CEQA Guidelines, a significant impact to a biological
resource would occur if implementation of the project would:
a. Have a substantial adverse effect, either directly or through habitat modifications, on a
species identified as a candidate, sensitive or special status species in local or regional plans,
policies or regulations, or by the CDFW or the USFWS;
b. Have a substantial adverse effect on any riparian habitat or other sensitive natural
community identified in local or regional plan s, policies, and regulations or by CDFW or
USFWS;
c. Have a substantial adverse effect on federally protected wetlands as defined by Section
404 of the Clean Water Act (including, but not limited to, marsh, riparian scrub, etc.)
through direct removal, filling, hydrological interruption or other means;
d. Interfere substantially with the movement of any native resident or migratory fish or wild life
species or with established native resident or migratory wildlife corridors, or impede the use
of native wildlife nursery sites;
e. Conflict with any local policies or ordinances protecting biological resources, such as tree
preservation policy or ordinance; or
f Conflict with the provisions of the City of Carlsbad HMP, NCCP or other approved local,
regional or state habitat conservation plan.
10.2 Quantification of Impacts
The Project plans indicate that the entire Property area will be impacted by the proposed project
development. Therefore a total of 0.35 acres of vegetation communities will be directly impacted.
However, since no sensitive habitats or special-status plants occur on the property, the project will not
result in impacts to any sensitive habitats or plants. Table 2 below quantifies the impacts to
vegetation communities on the subject property that will result from implementation of the project.

The driveway entrance at Adams Street will also include some minimal impacts to Disturbed Habitat
at Adams Street.
Thus it is concluded that, subject to compliance with Mitigation Measure BIO-1 below, the proposed
project will not have a substantial adverse effect, either directly or through habitat modifications, on a
species identified as a candidate, sensitive or special status species in the local HMP, or policies or
regulations, or by the CDFW or the USFWS.
Further, the proposed project will not have a substantial adverse effect on any riparian habitat or other
sensitive natural community because those vegetation communities do not exist on the property.
Since the project site is not directly adjacent to flammable, native vegetation, the project does not
require any fire modification or buffer zone. Since the project site is highly-disturbed and has been
regularly maintained, it will not result in a significant impact to wildlife.
Also, the project will not have a substantial adverse effect on federally protected wetlands as
defined by Section 404 of the Clean Water Act because no wetlands or other waters defined in the
Clean Water Act exist on the property. It is expected that the project will comply with all applicable
water quality regulations per the National Pollutant Discharge Elimination System permit process and
implement applicable Best Management Practices during construction activities. Erosion control
measures will be implemented to avoid drainage and sedimentation of downstream areas.
Additionally, the project is surrounded on three sides by residential development and will not
interfere substantially with the movement of any native resident or migratory fish or wild life species
or with established native resident or migratory wildlife corridors, or impede the use of native wildlife
nursery sites because the project is consistent with the HMP and complies with the wildlife corridors
identified in that plan.
The proposed project is not within a hardline or standards area and will not conflict with the HMP or
any other local policies or ordinances protecting biological resources, and as mentioned, it will not
conflict with the provisions of the City of Carlsbad HMP, NCCP or other approved local, regional or
state habitat conservation plan. Indirect impacts from the project on the HMP standards area south of
Adams Street could be significant during construction if the construction activities were to disturb or
otherwise negatively aff~ct bird nesting on this adjacent property. With the adoption of Mitigation
Measure BIO-2, which requires monitoring of construction noise, this possible indirect impact will be
mitigated to a level of less than significant.
11.0 MITIGATION MEASURES
Impacts associated with this project occur to 0.35 acre ofNNG and DH. These impacts will require
mitigation pursuant to the Carlsbad HMP regulations in order to reduce the impacts to a level of
insignificance. Notwithstanding that these land cover types are not considered sensitive habitats, the
vegetation is considered of value to fauna which utilize the vegetation area as foraging habitat, and
thus mitigation for impacts to NNG and DH is required in order to reduce the impacts to a level of
insignificance. The City HMP provides that these impacts may be mitigated for through payment of
an In-Lieu fee based on a City approved fee schedule. Thus Mitigation Measure BIO-1 is required in
order to reduce these impacts to a level of insignificance.

B1O-1. Prior to issuance of a grading permit, the project applicant will pay the per acre In-
Lieu mitigation fee for 0.15 acre of NNG and 0.20 acre of DH in an amount as determined by
the Carlsbad City Council.
Additionally, the project would not directly impact any federal or state threatened or endangered plant
or wildlife species. However the project has the potential to result in significant indirect impacts to
common and/or sensitive nesting birds potentially occurring within the Diegan Coastal Sage Scrub
(DCSS) located offsite and across Adams Street to the southwest. These indirect impacts could result
from construction noise levels if construction occurred during the nesting season. Thus these impacts
will be reduced to a level of insignificance with the implementation of Mitigation Measure BI0-2,
requiring biological monitoring of nesting season construction.
B1O-2. If grading of the site is planned during the avian breeding season (February 15 to
August 31); a qualified biologist shall conduct a pre-construction survey in the adjacent coastal
sage scrub habitat (south of Adams Street) for nesting California gnatcatchers. Please note that
the offsite suitable coastal sage scrub habitat is located on private land and authorization to
access the property to conduct the nesting surveys will require authorization by the landowner.
If authorization is granted, the bird survey shall take place not more than three days prior to
the beginning of clearing or grading activities. If authorization is not granted, reasonable
efforts will be made, in consultation with the biologist and the Carlsbad Planning Department
to minimize the construction noise experienced in the adjacent habitat. No activities which
would result in noise levels exceeding 60 dBA hourly Leq within at the off site coastal sage scrub
shall be allowed. A biologist shall monitor the noise levels. Ambient noise shall be excluded
from the 60 dBA calculation.
In light of these factors, project compliance with Mitigation Measures BI0-1 and BI0-2 above will
reduce all potential biological impacts to a level of less than significant. No other mitigation is
required.
