ENVIRONMENTAL IMPACT ASSESSMENT
ENVIRONMENTAL EVALUATION / EARLIER ANALYSES DISCUSSION
PROJECT BACKGROUND INFORMATION
A. Earlier Analysis and its applicability to project
See discussion under item # XVII. Earlier Analysis, below.
B. Environmental Analysis
The subdivision site consists of 27.7 acres of vacant land previously used for agricultural operations and surrounded
by residential and agricultural properties. The western portion of the site is crossed diagonally by an existing
SDG&E major power line easement. The elevations onsite vary from a high of about 316 feet in the northeastern
corner to a low of about 200 feet above mean sea level within the lower canyon area in the western portion of the
site. The site drains predominantly down the steep slope areas leading to a natural drainage which follows generally
along the SDG&E easement, flowing toward the north to Encinas Creek. The majority of the plateau portion of the
site has been cultivated in the past. The steep slope areas contain southern mixed chaparral and non-native
grassland. Some wetland habitat species are located along the lower drainage.
There are no major onsite or offsite facility improvements necessary for the development of the project.
Construction is currently underway for the westerly extension of Poinsettia Lane, south of the subject site, to Aviara
Parkway by the adjacent Ocean Bluff (Cantamar) development. Black Rail Road, located on the east side of the
adjacent easterly parcel, is also currently under construction by the Cobblestone (Marbrisa) development. Existing
improvements to the site include dirt roads, water lines and overhead powerlines.
I. LAND USE AND PLANNING
a) The proposal is consistent with the existing underlying General Plan designations of Residential Low Medium
(RLM) (0-4 du/ac) and Open Space (OS). A Zone Change is being processed concurrent with this application to
rezone the subject property from the "holding" zone of Limited Control (L-C) to One Family Residential (R-1-7500-
Q) with the Qualified Development Overlay, consistent with the existing general plan designation. This will not
alter the anticipated General Plan land use for the property and thus, no significant land use impacts are anticipated.
b) The proposed project does not conflict with any City of Carlsbad environmental plans or policies. The Roesch
parcel is subject to the Mello II Local Coastal Program (LCP). A Local Coastal Program Amendment (LCPA) is
required to change the zoning from L-C to R-l and is being processed concurrent with the project for this purpose.
The project is consistent with the Mello II land use policies.
c) The proposal is consistent with existing and proposed land use in the vicinity. Adjacent residential land use consists
of RLM designated properties with R-l and L-C zoning that have recently constructed or approved residential
subdivisions or are vacant with agricultural operations. The Sambi and Mariners Point subdivisions to the west and
southwest have recently completed construction and the Cobblestone (MarBrisa, CT 84-32A) residential subdivision
to the north and Ocean Bluff (Cantamar 93-09A) project adjacent to the east are currently under development. The
site Adjacent to the northwest has an approved TM for the Mariano (CT 97-14) single family subdivision. The
properties to the south and southeast are vacant or have existing agricultural operations onsite. A community park is
proposed at a site less than a quarter mile to the east.

Topographically, the southeastern quarter of the site is relatively flat and has been in agricultural use. Most of the
remaining portion of the site is represented by steep slopes leading to a drainage way. The proposed project will be
topographically separated and buffered from the adjacent parcels to the north, west and southwest by steep slope and
natural habitat areas as part of the project open space area. The project was designed to tie into the circulation
system of the adjacent Ocean Bluff development to the east.
Due to the project's direct access from Brigantine Drive off of Poinsettia Lane, project traffic would not impact
surrounding properties. The projected ADT for this 21 unit residential project (210 ADT) is also considerably less
than the number of average daily trips (590 ADT), determined by multiplying the net acres onsite by the growth
control factor of 3.2, which was allocated for in the Zone 20 LFMP and Specific Plan, based on a gross analysis of
the entire zone.
d) Approximately a quarter of the site has historically been used for agricultural cultivation. The project site is located
outside of the Coastal Agricultural Overlay Zone (Sites II and III) of the Mello II Segment of Carlsbad's Local
Coastal Program. Thus, the mitigation options provided in the Local Coastal Plan (LCP) for the conversion of
agricultural lands to urban uses are not required including the option to pay an agricultural conversion mitigation
fee. The PEIR required mitigation to reduce impacts to neighboring properties which provide agricultural uses (i.e.
to the south) including notification to future residential land owners that this area is subject to dust, pesticide, and
odors associated with adjacent agricultural operations will still apply. The provision of temporary road connections
to maintain continued access to adjacent agricultural properties to the south should not be necessary during
construction as these parcels should have access via Aviara Parkway, Poinsettia Lane, and/or Brigantine Drive.
e) The project site is located within an area of the City which has recently being developed, including the Cobblestone,
Sambi, Mariners Point and Ocean Bluff subdivisions to the north, west, southwest, and east, respectively and the
approved Mariano development to the northwest. The proposed project will not adversely impact the access to
these subdivisions as the onsite circulation was designed to tie into the surrounding circulation patterns. Potential
residential developments to the south and southeast will not be adversely impacted. Accordingly, this proposed 21
lot residential subdivision project will not disrupt or divide the physical arrangement of an established community.
II. POPULATION AND HOUSING
a) The City of Carlsbad's Growth Management Program established performance standards for public facilities, a
population limit and a housing limit at buildout of the City. The proposed project contains fewer units than was
anticipated in the Zone 20 LFMP. The anticipated density based on the allowed growth management control point
multiplied by the site net acreage (as analyzed on a zone basis in the facilities plan) provides for 59 units for the
subject parcel, whereas 21 units are currently being proposed. Thus, the Citywide Growth Management dwelling
unit and population buildout caps will not be exceeded and public facilities and services will be available to meet the
anticipated demand for the project.
b) As specified by the Zone 20 PEIR, the development of projects including transportation routes, public services, and
land uses within the Zone 20 planning area is not growth inducing since the area has been previously planned and
designated for residential development by the City's General Plan, Growth Management Program, and Zone 20
LFMP. The provision of Poinsettia Lane, to be constructed offsite to the south as a condition of adjacent
subdivisions, will provide the final segment of the extension from Aviara Parkway to the Aviara Phase III project.
There are no major offsite facility improvements required for this development, thus there would be no impacts on
growth in the area. Also, development already exists to the east, west, north, and south of Zone 20 properties;
therefore, urbanization of the area is inevitable.
c) The project site is currently undeveloped, so no existing housing will be displaced. No existing affordable housing
units will be negatively impacted by the proposed development. The project proposes to satisfy the 15%
inclusionary housing requirement by purchasing 3.15 offsite credits in the existing Villa Loma affordable apartment
project. The offsite proposal for this property was acknowledged by the Carlsbad Housing Commission in their
review of the southwest quadrant analysis regarding the use of affordable housing credits in the Villa Loma project.

III. GEOLOGIC PROBLEMS
Consistent with the PEIR for Environmental Area I, an additional geotechnical investigation has been prepared for
the project. The Soil and Geologic Reconnaissance, Roesch Property, prepared by Geocon, Inc., dated April, 1998
states that "in our opinion, no soil, groundwater, and/or geologic conditions exist at the site that would preclude the
development of the property as presently considered, provided the recommendations of this report are followed".
Geotechnical recommendations will be incorporated as project conditions in accordance with the Zone 20 PEIR.
a, b) Faulting & Seismicity - According to the geotechnical report, "a review of geologic literature, experience with the
soil and geologic conditions in the general area, and observations during the field investigation indicate that no
active faults are located at the site. The nearest known active fault is the Rose Canyon Fault Zone located
approximately 7 miles west of the site." "Proposed improvements should, however, consider seismic design
requirements in accordance with locally applicable governing agency codes."
c) Liquefaction - As stated in the report: "liquefaction occurs in loose cohesionless soils located below the water table
that are subjected to large accelerations during strong earthquakes. Due to the very dense nature of the formational
units, the removal and recompaction of the surficial soils, and the lack of a permanent groundwater table, the
potential for liquefaction of the site subsoils is considered to be very low."
d) Seiche, tsunami, or volcanic hazard - Because there are no volcanoes located within the City of Carlsbad and
because the project site is not located proximate to a bay, lake or ocean, no impacts involving seiches, tsunamis or
volcanic hazards are anticipated.
e) Landslides or mudflows - The Santiago Formation typically possesses weak claystone seams and fractures that may
be subject to slope instability. Observations during the field reconnaissance and review of stereoscopic aerial
photographs revealed characteristic topography of three landslides within the western portion of the proposed
development. Subsurface investigation is required to verify the existence and extent of the potential landslides.
IV. WATER
a,c,d) Additional impervious surfaces will be created with development of the project, which as a result, reduces
absorption rates and increases surface runoff. Grading permit standards and the Zone 20 Local Facilities
Management Plan require adequate drainage facilities to service the site. Post development surface runoff must not
carry any increased velocity at the property line from a 10-year/6 hour storm event based on the hydrology standards
of the Mello II Segment of Carlsbad's Local Coastal Program. Compliance with the National Pollution Discharge
Elimination System (NPDES) requirements will reduce surface pollutants to an acceptable level prior to discharge.
These measures and erosion control mitigations (i.e. landscaping, adequate drainage facilities and proper soil
compaction) will serve toward reducing water quality impacts to below a level of significance.
b) The project site is not located within a floodplain or within an area which is subject to flooding. Due to the site's
elevation and the proposed grading, there is little risk of flooding on the proposed site building pads. Also, with the
construction of an adequate on-site drainage system and proper finish surface grades, the risk of flooding should be
minimized within the proposed building areas. Therefore, no portions of the property or future project residents
would be exposed to flood hazards.
e) A natural drainageway is located within the western portion of the site, generally trending north/south along the
SDGE easement, which flows northerly to Encinas Creek. The proposed project is designed to not affect this
drainage area, to leave it in a natural state in a permanent open space easement. Drainage control measures will be
incorporated into the project design to ensure that the project will not change the course or flow of water toward the
creek.
f-i) There exist no potable ground water basins within the City. According to the geotechnical report, "No groundwater
or seepage was observed within the property or encountered during our site reconnaissance. Perched groundwater
can be expected to occur within alluvial soils during remedial grading. However, it is not anticipated that
groundwater will adversely affect the project or present a hazard to the site." Due to project drainage, erosion

ROESCH PROPERTY

JHA/mka/EIA
control prevention measures, and depth of ground water onsite, no impacts to groundwater quantity, quality, or
direction or rate of flow are anticipated.
V. AIR QUALITY
a) In that a greater number of units were allocated in projections for development of the area, the air quality impacts for
this 21-unit project have already been considered in the Master EIR for the Updated 1994 Carlsbad General Plan.
The 21 units proposed will present less air quality impacts than the 59 units assumed for the property in projected
buildout calculations. The project also implements various air quality mitigation measures. For example, due to the
location of new units in close proximity to a major roadway (Poinsettia Lane) and employment opportunities,
vehicle cold starts, vehicle trip lengths and roadway congestion may be reduced in that residents are more likely to
bike or walk to work.
Operation-related emissions are considered cumulatively significant because the project is located within a "non-
attainment basin", therefore, the "Initial Study" checklist is marked "Potentially Significant Impact". This project is
consistent with the General Plan, therefore, the preparation of an EIR is not required because the certification of
Final Master EIR 93-01, by the City Council Resolution No. 94-246, included a "Statement Of Overriding
Considerations" for air quality impacts. This "Statement of Overriding Consideration" applies to all subsequent
projects covered by the General Plan's Final Master EIR, including this project, therefore, no further environmental
review of air quality impacts is required. This document is available at the Planning Department. The applicable
and appropriate General Plan air quality mitigation measures have been incorporated into the design of the project or
will be included as conditions of project approval.
Construction activities associated with the project would result in potential short-term air quality impacts. Principal
pollutants from these activities include fugitive dust particles due to grading and transportation of construction
materials and, to a lesser degree, emissions from construction vehicles. The Grading Ordinance contains provisions
to minimize the release of construction related pollutants; therefore, air quality impacts resulting from future project
related construction activities would not be considered significant in that the project shall be conditioned to comply
with the Grading Ordinance.
b) Other than project air emissions associated with gas and electric power consumption and vehicle miles traveled, this
21 unit residential project will not generate any other air pollutants. There exist no sensitive receptors (schools or
hospitals) within close proximity to the project site, therefore potential exposure of sensitive receptors to project air
emissions is not considered a significant impact.
c,d) Because of the project's small size (21 dwelling units) and it's location within a relatively developed area, no
significant impacts to air movement, moisture, temperature, or climate are anticipated. This residential project is not
anticipated to create objectionable odors.
VI. TRANSPORTATION/CIRCULATION
a) To lessen or minimize the impact on circulation associated with General Plan buildout, numerous mitigation
measures have been recommended in the Final Master EIR. These include 1) measures to ensure the provision of
circulation facilities concurrent with need; 2) provisions to develop alternative modes of transportation such as trails,
bicycle routes, additional sidewalks, pedestrian linkages, and commuter rail systems; and 3) participation in regional
circulation strategies when adopted. The diversion of regional through traffic from a failing Interstate or State
Highway onto City streets creates impacts that are not within the jurisdiction of the City to control. The applicable
and appropriate General Plan circulation mitigation measures have either been incorporated into the design of the
project or are included as conditions of project approval.
Regional related circulation impacts are considered cumulatively significant because of the failure of intersections at
buildout of the General Plan due to regional through-traffic, therefore, the "Initial Study" checklist is marked
"Potentially Significant Impact". This project is consistent with the General Plan, therefore, the preparation of an
EIR is not required because the certification of Final Master EIR 93-01, by City Council Resolution No. 94-246,
included a "Statement of Overriding Considerations" for circulation impacts. This "Statement" applies to all
4 JACK HENTHORN & ASSOCIATES
ROESCH PROPERTY
December 9, 1998
JHA/mka/EIA
subsequent projects covered by the General Plan's Master EIR, including this project, therefore, no further
environmental review of circulation impacts is required.
The proposed project would generate approximately 210 ADT. A Circulation Impact Analysis is not required for
projects proposing an increase of less than 500 ADT's. The project is providing access from Brigantine Drive off of
Poinsettia Lane. Poinsettia Lane is being constructed to the south by adjacent developments. The major
improvements identified in the Zone 20 LFMP have already been installed or are currently being provided for by
other nearby developments to accommodate increased vehicle trips and mitigate traffic congestion. It is anticipated
that with the implementation of these circulation improvements, all corridors and intersections in the project vicinity
would operate at acceptable levels of service and there would be no significant circulation or traffic impacts.
b,c) All project on-site circulation improvements shall be required to comply with minimum engineering design and
safety standards. Internal access between the project site and the adjacent development to the east is provided in the
design. The onsite circulation is designed in accordance with the General Plan Circulation Element and City
standards thereby avoiding hazards to safety from design features. Additionally, temporary road connections to
maintain continued access to adjacent agricultural properties that could be impacted by future improvements will be
provided, as needed.
d) Required parking will be provided onsite. Each proposed lot will be required to have a minimum 2-car garage per
single family unit.
e) Pedestrian and bicycle access will be accommodated by standard full width right of way improvements including
sidewalks along all internal streets.
f) The project as proposed complies with adopted policies supporting alternative transportation. Specifically, in that
the project will be located in proximity to a major roadway (Poinsettia Lane) and employment opportunities within
the surrounding businessparks, and that alternative transportation opportunities exist including bus transit, and
bicycle or pedestrian access.
g) The project is not located in close proximity to a railroad or navigable waterway, therefore, no rail or waterborne
impacts are anticipated. The project is also consistent with the McClellan Palomar Airport Comprehensive Land
Use Plan and located outside of the Airport Influence Area. Therefore, no air traffic impacts are anticipated.
VII. BIOLOGICAL RESOURCES
a-e) See "Biological Resources Assessment of the Roesch Site" dated December 4, 1998, prepared by Natural Resource
Consultants. This subsequent biological study provides a focused, current and detailed project level analysis of the
site specific biological impacts and provides project level mitigation measures.
VIII. ENERGY AND MINERAL RESOURCES
a) Consistent with Title 24 regulations of the State Building Code, the project will be designed to incorporate energy
conservation measures where feasible. Otherwise, the project does not conflict with any adopted energy
conservation plans.
b) The project's compliance with Building Codes, Title 20, and Chapter 17 of the Municipal Code in accordance with
the MEIR (Electricity and Natural Gas Section) mitigation measures to reduce impacts associated with the use of
nonrenewable resources in a wasteful manner will ensure the implementation of energy conservation measures. The
subject property does not contain any known non-renewable resources of any significance, so no non-renewable
resources will be used in a wasteful or inefficient manner.
c) The subject property does not contain any known mineral resources (natural gas, oil, coal or gravel) that would be of
future value to the region and the residents of the State.

IX. HAZARDS
a,b,c) A single family residential project is not a use typically associated with risks such as accidental explosion or release
of hazardous substances, thereby creating a potential health hazard. Although agricultural operations may continue
on parcels in the vicinity of the Roesch subdivision, compliance with the Zone 20 PEIR measures and Zone 20
Specific Plan development regulations to buffer residential development from agricultural operations will avoid
health hazards resulting from pesticide residue. This 21-unit residential project will not create any health hazard.
The project will, also not interfere with an emergency response plan or emergency evacuation plan.
d) The project site has been previously used for agricultural purposes so the potential exists for soil contamination. The
soil may be tested for pesticide residue. If significant levels of pesticide residue are present in the soil, appropriate
mitigation measures shall be followed.
e) This project has native vegetation located onsite and on adjacent properties offsite, which could be subject to fire
hazard. Pursuant to the City's Landscape Manual, a Fire Suppression Plan is proposed to mitigate future potential
fire hazards.
X. NOISE
a) Implementation of the proposed 21 unit project will incrementally increase existing noise levels in the project
vicinity. However, the increased noise associated with 21 residential single-family units (and 210 additional average
daily auto trips) would not result in a significant increase in noise levels within the project vicinity.
b) There will not be significant impacts to the project created by traffic noise from future Poinsettia Lane provided that
the required acoustical report's recommended mitigation measures are adhered to. A sound wall is not required
onsite because exterior traffic noise on the adjacent lots falls below 60 dB(A) CNEL. This is due to a combination
of items: 1) the projected ADT's on Poinsettia Lane are not as high as other arterial roadways (i.e. Aviara Parkway);
2) there is a significant topographic variation between the roadway and the pads; and future development on the
parcels between the subject site and Poinsettia Lane will further buffer the site from traffic noise. The proposed 5'
high wood fence located along the rear yards of Lots 20 and 21 will provide additional noise attenuation from
Poinsettia Lane. There is no development proposed within over 600 feet from Aviara Parkway and no acoustical
mitigations are necessary in association to this roadway. Prior to the issuance of building permits for this project,
the project applicant may be conditioned to submit an acoustical analysis to the City which analyzes and
recommends mitigation measures to limit interior noise levels to less than 45 dBA CNEL.
Based on exhibits in the McClellan-Palomar Comprehensive Land Use Plan and Zone 20 Specific Plan, the project
site is located south of the CNEL noise contours for the McClellan-Palomar Airport and thus, should not be
negatively impacted by overflight or noise generated by the airport.
XL PUBLIC SERVICES
a-e) In accordance with the City's MEIR, the project must be consistent with and will be conditioned to comply with the
City's adopted Growth Management performance standards for public facilities and services to ensure that adequate
public facilities are provided prior to or concurrent with development. The project is within and subject to the Zone
20 Specific Plan requiring it to be in accordance with the approved Zone 20 LFMP thereby ensuring that
performance standards for public facilities will be met through build-out of the zone.
Consistent with the City's Growth Management Plan and applicable state law, the project applicant shall be required
to submit evidence to the City that project impacts to school facilities have been adequately mitigated prior to the
issuance of a grading or building permit. The project mitigation will involve a financial contribution to the Carlsbad
Unified School District, Community Facilities District (CFD) fund.

XIII. AESTHETICS
a,b) Perimeter landscaping and existing City building height restrictions will mitigate potential negative aesthetic impacts
of the project.
Development of the project requires 42,700 cubic yards of grading. This results in acceptable grading quantities of
6,280 cubic yards per graded acre . The proposed grading conforms to the City's revised Hillside Development
Ordinance. Manufactured slopes will be screened with landscaping. Cut slopes will not exceed 16 feet and fill
slopes will not exceed 40 feet in height. The proposed development follows the natural countours of the existing
topography by preserving the topographic integrity of the relatively flat mesa and preserving the more extreme
variations in topography in the canyonarea in a proposed permanent open space easement. Therefore, the alteration
of the topography would not create a significant aesthetic impact.
The Zone 20 PEIR includes a visual impact analysis and provides architectural design guidelines that new
development should comply with. The viewshed analysis determined that any potential impacts to the Palomar
Airport Road viewshed (Section 3.13.2.2.4) would not be significant as the views from this location are not
"visually sensitive". The El Camino Real viewshed (Section 3.13.2.2.5) was also determined not to be significant
due to the distance from the site and the high speeds at which the motorist is traveling at, results in viewing only a
small percentage of the Specific Plan Area. The architectural guidelines suggest that building products be varied
with one and two story-elements. This site should not be constrained to single story units over a portion of the
subdivision as it is not a ridgeline development.
c) The project would not create significant light and glare impacts on surrounding properties. The site would be
buffered from surrounding properties by building setbacks, topography, slope landscaping, and open space areas
with natural vegetation. In addition, the project shall be conditioned so that all project lighting be designed to reflect
downward to avoid impacts to surrounding properties.
XIV. CULTURAL RESOURCES
a-e) Paleontological and historical resources were analyzed in the Zone 20, Specific Plan PEIR by RMW Paleo
Associates and Brian Mooney Associates, respectively. There were no cultural resource sites identified in these
studies within the Roesch Property site. The paleontology report suggested that "capping the study area are
Quaternary age marine terrace deposits. ... No fossils are known from these deposits in the study area. ... The
Quaternary age marine terrace deposits have a low potential for the discovery of fossils."
XV. RECREATION
a, b) On-site recreational amenities will be provided individually for each 7,500 minimum square-foot, single family lot.
In addition, Aviara Park is proposed to the east less than a quarter mile away and Poinsettia Community Park (42
acres) is located less than 1/2 mile to the west. Accordingly, project impacts to recreational amenities are not
regarded as significant.
XVI. MANDATORY FINDINGS OF SIGNIFICANCE
a) As discussed in the attached Biological Resources report, the project will result in the loss of 1.37 acres of southern
maritime chaparral habitat. However, project design mitigates direct impacts to southern maritime chaparral by
proposing an open space easement over 74% of the native habitat area onsite. This area is also considered valuable
in the City's draft HMP document as a part of Linkage Area F.
b) All project related impacts must be considered to be cumulatively considerable when viewed in connection with the
effects of continued growth and development within the City, Northern San Diego County and San Diego County in
general. However, with the exception of significant and unmitigable regional air quality impacts identified within
the Master EIR for the City's Updated 1994 General Plan, (for which a Statement of Overriding Considerations has
been adopted by the Carlsbad City Council), this project will implement project specific mitigation measures to
reduce project specific impacts to a level of insignificance. The implementation of these project mitigation measures
will incrementally reduce cumulative considerable impacts to a level of insignificance.

c) As previously discussed within this document, this 21 unit residential, detached single family project will not create
environmental effects which will cause substantial adverse effects on human beings either directly or indirectly.
Alternatives:
Project alternatives are required when there is evidence that the proect will have a significant adverse impact on the
environment and an alternative would lessen or mitigate those adverse impacts. Public Resources Code Section 21002
forbids the approval of projects with significant adverse impacts when feasible alternatives or mitigation measures can
substantially lessen such impacts. A "significant effect" is defined as one which has a substantial adverse impact. Given
related project mitigation conditions, this project has "NO" significant physical environmental impacts, therefore, there is
no substantial adverse impact and no justification for requiring a discussion of alternatives (an alternative would not lessen
an impact if there is no substantial adverse impact).
XVII. EARLIER ANALYSES
a,b) Earlier analysis of this proposed single family residential project has been completed through the 1994 General Plan
Update (GPA 94-01) and related Master Environmental Impact Report (MEIR 93-01). The MEIR is cited as source #1 in
the preceding checklist. This proposal is consistent with the applicable portions of the General Plan and is considered a
project that was described in MEIR 93-01 as within its scope. All feasible mitigation measures identified in MEIR 93-01
which are appropriate to the project have been incorporated into this project.
The project site is located within the area subject to the requirements of the Zone 20 Specific Plan. CEQA compliance for
the specific plan was achieved through the certification of the Zone 20 Program EIR which identified, analyzed, and
recommended mitigation to reduce potentially significant impacts to insignificant levels. The Zone 20 Program EIR
(PEIR) analyzed potential impacts to agriculture, air quality, biology, circulation, land use, noise, pesticide residue,
paleontology, public facilities financing, soils/geology, and visual aesthetics that could result from the development of the
Specific Plan area. The Program EIR was intended to be used in the review of subsequent projects within Zone 20. This
project incorporates the required Zone 20 PEIR mitigation measures and, through the analysis of the required additional
biological, geotechnical, hydrological, and acoustical analyses, a determination can be made that no additional significant
impacts beyond those identified and mitigated by the Program EIR will result from this project and no additional
environmental documentation is required (Prior Compliance). The following environmental evaluation briefly explains the
basis for this determination along with identifying the source documents which support the environmental determination.
The Zone 20 Program EIR and additional technical studies are cited as source documents for this environmental evaluation.
