B. Proiect Description
The proposed project consists of the development of two High Tech High public charter schools and
an Environmental Research Center (ERe) on approximately 10 acres of undeveloped land located in
eastern Chula Vista (refer to Figure 2). The proposed project would be constructed in two phases:
Phase One consists of a 64,000 square-foot (sf) 9" through 12" grade high school and environmental
research center that will accommodate 550 students and 36 faculty members on an approximate 8-
acre parcel. Phase Two would include the addition of a 70,000 sf K_81h grade school that will
accommodate an additional 700 students and 47 faculty members on an adjacent 2-acre parcel. School
phasing is summarized in Table I below. Each school building would include classrooms, specialty
labs, administration offices, a commons/dining area, and supportlbuilding core facilities.

Outside areas would include leaming patios, plazas, walkways, dining terraces, play yards
including half basketball courts, green space, areas for drop off and pick-up, and parking
spaces for cars and bicycles.
The ERC will be highly integrated with the high school and will consist of specialty labs,
outdoor growing areas, and other facilities for environmentally- focused research and
teaching involving students, faculty, and visiting researchers and community members.
Ancillary activities and programs including, but not limited to, fundraising, athletic,
preschool, childcare, adult education, research, performing arts, and community events may
take place on the campus before, during, or after regular school hours and on weekends and
holidays as well. The completed project will include grading to create appropriate building
pads, on-site parking, open recreational space, landscaping, lighting, signage, pedestrian
pathways, fencing, and retaining walls. Proposed lighting will consist of standard security,
pathway, and parking lighting standards. The proposed project will also evaluate the use of
an approximate l2-acre borrow immediately adjacent to the site that would provide 400,000
cubic yards of soils needed to create the building pads and a relatively flat campus. The
overall impact area (campus, access roads, slopes, and borrow area) encompasses
approximately 26 acres.
Zone Change
A redesignation of the lO-acre school site from Planned Community (PC) zone to
Public/Ouasi-Public WoO) zone is DroDosed in order to allow a DubEe use within University
Campus area Drior to the processing of the University Campus Sectional Planning Area
(SPA) Plan.

Hours of ODe ration:
The proposed schools and ERC would generally operate between 8:30 AM to 4:00 PM
Monday through Friday, with limited ancillary activities offered before and after school
hours and weekends and holidays as well. The start and end times for the different schools
may be staggered to minimize traffic congestion during peak drop-off and pick-up times.
Parking:
The proposed project would meet the minimum requirements set forth in the Chula Vista
Municipal Code for on-site parking for the two schools. Because the research center is an
extension of the high school and will have no faculty, staff, or students independent of the
schools, no additional parking is required for this facility.
LEED Certification
The proposed project is in the process of seeking certification through the Collaborative for
High Performance Schools and the latest US Green Building Council Certification:
Leadership in Energy and Environmental Design (LEED) for Schools. Measures that would
be implemented to achieve certification include, but are not limited, to integrating a 50kW
photovoltaic system in the roof design, imposing a minimum daylight factor of 2% in at least
75% of classrooms and regularly-occupied spaces, and installation of a Building
Management System (BMS) will be integrated with the lighting, irrigation, and mechanical
system to maximize energy and water efficiency. The project encourages alternative
transportation by including bicycle storage and changing facilities. Similarly, parking areas
would include preferred parking for low emitting/fuel-efficient vehicles as well as preferred
parking for carpools, which would encourage alternative transportation options. In order to
improve energy use, the project would exceed the standard California Title-24 Energy Code
by a minimum of 15 percent.
C. Comoliance with Zoning and Plans
The proposed project site is located in the P-C Zone (Planned Community/Otay Ranch
University Campus) and PQ (public/Quasi-Public) General Plan land use designation. The
proposed project is consistent with the goals, objectives, and policies of the City's General Plan
and Otay Ranch General Development Plan (GDP) for the establishment of educational and
research institutions within this area. A redesignation of the proposed school site from PC
zone to P-Q zone is proposed to allow for a public use within University Campus area prior
to the processing of the University Campus Sectional Planning Area (SPA) Plan.
Otay Ranch General Development Plan/Subregional Plan Program EIR
The Final Program Environmental hnpact Report (Program EIR #90-01) for Olay Ranch
General Development Plan/Subregional Plan (GDP/SRP) was prepared and certified jointly
by the City of Chula Vista and County of San Diego. The Program EIR 90-0 I addresses the

Page I environmental Impacts of implementation of the Otay Ranch GPNGDP/SRP and related
documents, which include Facility Implementation Plans, a Village Phasing Plan, Phase One
Resource Management Plan (RMP), and a ServiceIRevenue Plan. As part of Program EIR
90-01, a Mitigation Monitoring and Reporting Program (MMRP) was prepared to define
implementation of the mitigation measures described in the Program EIR. Relative to the
project site, the Program EIR identified potentially significant impacts associated with
agricultural resources, landform development, biological resources, and air quality with
build-out of the site in accordance with the GDP.
A Statement of Overriding Considerations was adopted for Program EIR #90-01 that
addressed impacts to agricultural resources, landform development, biological resources, and
air quality within the development area of the proposed project. Thus, the potential impacts
(direct andlor cumulative) associated with agricultural resources, landform development,
biological resources, and air quality within this area have been assumed, considered and
approved through the adoption of the Statement of Overriding Considerations for the Otay
Ranch GDP.
D. Public Comments
On July 13, 2007, a Notice of Initial Study was circulated to property owners and residents
within a SOD-foot radius of the proposed project site. The notice period ended July 2S, 2007.
Two written comment letters were received during the public review period. The comment
letters included comments pertaining to the project's exemption of school fees from Chula
Vista Elementary School District, consistency with the Olay Ranch General Development
Plan, biological resources, water quality, air quality, and project alternatives. The issues
regarding biological resources, water quality, and air quality are addressed in the Mitigated
Negative Declaration sections below.
On November 7. 2007 a Notice of Availabilitv of the Proposed Mitigated Negative
Declaration for the proiect was posted in the County Clerk's Office and circulated to oroDertv
owners and residents within a SOO-foot radius of the proiect as well as those individuals who
have requested to be notified but who are located bevond the SOO-foot radius. The 30-dav
public comment Deriod closed on December 7.2007.
The Citv received I comment letter during the 30-dav public review Deriod. The comment
letter was submitted iointlv bv the Californian Deoartment of Fish and Game and US Fish
and Wildlife Service (Wildlife Agencies). The Wildlife Agencies expressed a concern
regarding: I) the draft mitigation language for landscaDing requirements and. 2) the potential
for Burrowing Owls to be Dresent on site. The issues raised in these letters have been
addressed in the Mitigated Negative Declaration and attached checklist. as well as in the
attached response to comments (Attachment "B").

E. Identification of Environmental Effects
An Initial Study conducted by the City of Chula Vista (including the attached Environmental
Checklist form) determined that although the proposed project could have a significant
envirorunental effect, there would not be a significant effect in this case because mitigation
measures described in Section F below have been added to the project. Therefore, the
preparation of an Envirorunental Impact Report will not be required. This Mitigated
Negative Declaration has been prepared in accordance with Section 15070 of the State
CEQA Guidelines.
AESTHETICS
Steep SloDe Analvsis
The Otay Ranch General Development Plan (GDP) and Resource Management Plan (RMP)
established a ranch-wide standard that required preservation of at least 83 percent of the steep
slopes (slopes with gradients of 25% or greater) throughout the Otay Ranch. As an
implementing action of the GDP/RMP, a steep slope allocation table was provided a part of
the Phase 2 RMP (Exhibit 29). Geographically, the project site is located within the
University Campus planning area (formerly referred to as Otay Ranch Village 10). The
original steep slope tabulation assumed that approximately 1,30 I steep slopes acres would be
impacted, and specifically allocated 55.7 acres of steep slope impact to Village 10.
In November 1998, the Sectional Planning Area (SPA) One Planrevised the original steep
slope allocations to Villages One, Five, Thirteen and Fifteen. Based on this reallocation, the
total number of estimated steep slopes impacts in Otay Ranch was reduced to 1,281.5 acres.
Overall, the SPA One revisions resulted in a net surplus of 18.8 acres of steep slope
encroachment as compared to the originally forecasted GDP impact of 1,301 acres. In
addition, based on a current tabulation for completed SPA plans (Villages One, Five, Six,
Eleven, and the Freeway Commercial), it has been estimated that an additional 1.0 acres of
steep slopes were not impacted as a part ofthe grading for these projects. The combination
of both of these totals results in a total surplus of19.8 (18.8 + 1.0) acres of steep slopes that
can be impacted, while still maintaining the 83% slope preservation standard.
The Phase 2 RMP requires that the application of the preservation standard must be reviewed
and monitored as additional projects are processed within the Otay Ranch GDP Planning
Area to ensure that the ranch-wide goal of steep slope preservation is maintained. The
project area includes approximately .35 acres of impacted steep slopes (Steep Slope Review,
REF, September 6, 2007). This estimated impact to steep slopes within Village 10 would not
exceed the RMP steep slope allocation of 55.7 acres. Therefore, implementation of the
proposed project would not significantly impact the ranch-wide steep slope preservation
standard.

Page lAir Qualitv
To assess potential air quality impacts ofthe project, an Air Quality Assessment for the High
Tech High University Park, dated September 19, 2007 was prepared by RFB Consulting.
The results of this analysis are summarized below.
Thresholds of Significance
To determine whether a project would create potential air quality impacts, the City evaluates
project emissions thresholds in accordance with the South Coast Air Quality Management
District (SQAMD) standards.
Short-Term Emissions (Construction)
As stated in the air quality assessment, all grading activities, including those for Phase II
development, would occur with the development of Phase 1. As such, Phase II
implementation consisted of construction of building facilities. Construction equipment used
for grading would include graders, off-highway vehicles, and tractors. Approximately
400,000 cubic yards of earth would be moved from an adjacent borrow site in order to create
building pads and a relatively flat campus. The project, as proposed, would be balanced and
does not include soil hauling from off-site locations.
The results of the air quality modeling for short-term construction operations are presented
below in Table 2. Based on the results of the air quality assessment, the proposed project
would exceed SCAQMDs thresholds for both PMIO and PMZ5 without implementation of
mitigation measures during grading operations. Other project emissions associated with
grading activities, including CO, ROG, NO" and SOx, would not exceed SCAQMD
thresholds.

J. The reduction/credits for constnlctionemission mitigations are based on mitigation included in the URBEMIS 2002 computer model
and as typically required by the SCAQMD. The mitigation includes the following: properly maintain or mobile and other
construction equipment; replace ground cover in disturbed areas quickly; water exposed surfaces thrtt times daily; cover stock. piles
with tarps; water all haul roads three times daily; and limit speeds on unpaved roads to 15 miles per hour.

The mitigation measures contained in Section F below would reduce short-tenn construction
related impacts to a level ofless than significant. These measures are included as a part of the
Mitigation Measure Monitoring and Reporting Program.
Cumulative Short-Term Emissions
Other projects in the area include the Sweetwater Union High School District (SUSHD)
Middle School 12 I High School 14 project, Eastern Urban Center (EUC), and the Otay
Ranch Village 2 SPA Plan. Both the EVC and SUHSD projects are currently in development
planning and have yet to obtain building entitlements. The Olay Ranch Village 2 SPA Plan
has been approved and is currently under construction and discussed below. Mass and rough
grading of the SUSHD Middle School were completed as part of initial grading activities for
the Otay Ranch Village II SPA Plan development, while grading of the EUC is not expected
to occur until mid to late 2008. By comparison, grading of the proposed project is expected
to be complete by early 2008. Therefore, for the purposes of this evaluation, it was assumed
that grading operations associated with the proposed project would not occur simultaneously
with grading operations associated with either the EUC or SUSHD developments.
The Otay Ranch Village 2 SPA Plan development is located approximately 1.5 miles west of
the proposed project and is currently in various stages of construction including: mass, rough,
and precise grading. As indicated above under the discussion of Short-tenn Emissions, the

age PMIO emissions are associated with fugitive dust particles, which would primarily affect
sensitive receptors within the immediate area of grading operations. The air quality modeling
prepared for the Otay Ranch Village 2 SPA Plan Final Environmental Impact Report (FEIR
02-02) concluded that impacts associated with construction emissions, including PMIO, would
be less than significant with the incorporation of mitigation measures. Similarly, as indicated
in Table 2 above, the proposed project also would not result in exceeding the SCAQMD
thresholds for PMIO with the implementation of project specific mitigation measures
including, but not limited to: watering of exposed surfaces three times daily; covering stock
piles 'with tarps; watering all haul roads three times daily; and limiting speeds on unpaved
roads to 15 miles per hour.
Therefore, based upon the distance separating the proposed proj ect from Otay Ranch Village
2 SPA Plan development and localized effect of PM 10 emissions, the findings and mitigation
measures contained in FEIR 02-02, and the air quality analysis performed for the proposed
project, the proposed project's incremental contribution to short-term cumulative
construction impacts would be considered less than significant.
Long-Term. Year 2010 and 2030 Emissions (Operation)
For purposes of this air quality emissions analysis, operational related air quality impacts
were studied for Year 2010 and 2030 buildout. Emissions were quantified based on the
buildout of both Phase 1 and Phase II. Long-term air quality impacts would consist of mobile
source emissions generated from project-related traffic and from stationary source emissions
generated directly from naturaJ gas. Emissions associated with each of these sources are
shown in Table 3 below. Based on the results of the air quaJity assessment, the proposed
project would not result in significant long-term air quality impacts.

Cumulative Long-Term Impacts
Implementation of the proposed project would result in an increase in emissions, which
would contribute to region-wide emissions on a cumulative basis. Based on the analysis
provided, the proposed project would not result in an exceedance of criteria pollutants for
long-term operational impacts. The proposed project would also be consistent with the land
use designations provided in the City's General Plan. Therefore, the proposed project would
result in a less than significant impact regarding cumulative impacts.
CO Analysis (Hot Spots)
In order to determine the potential for significant air quality impacts associated with CO
emissions, an evaluation of CO hot spots was completed. This was done to determine if the
proposed project emissions exceeded the acceptable regional criteria and violated the CO
standard. The CO "hot spots" were based upon the findings of the project traffic study.
According to the Traffic Impact Analysis, full build out of the project would warrant a CO
hotspot analysis at the Olympic ParkwaylEastlake Parkway and Birch RoadlEastlake
Parkway intersections. Future CO projections for these intersections were modeled using the
existing lane configurations. The projected traffic volumes were then modeled using the
CALINE4 dispersion model and the resultant values were added to an ambient concentration.
Based on the results of the CO hot spot analysis, the surrounding intersections would not
result in exceeding Federal or State CO standards; therefore, impacts would be considered
less than significant.
City ofChula Vista CO2 Reduction Plan
In order to reduce greenhouse gas emissions, the City of Chula Vista has prepared the CO2
Reduction Plan. The CO2 Reduction Plan aims to reduce CO2 emissions to 80 percent of
1990 levels by the year 2010. As a response to the City's C02 Reduction Plan, the proposed
project is in the process of seeking certification through the Collaborative for High
Performance Schools and the latest US Green Building Council Certification: LEED for
Schools. In accordance with eh City's CO2 Reduction Plan and to aid in achieving LEED
Certification, the proposed project includes, but is not limited to: integrating a 50kW
photovoltaic system in the roof design, imposing a minimum daylight factor of 2% in at least
75% of classrooms and regularly-occupied spaces, and installation of a Building
Management System (BMS) will be integrated with the lighting, irrigation, and mechanical
system to maximize energy and water efficiency. The project encourages alternative
transportation by including bicycle storage and changing facilities. Similarly, parking areas
would include preferred parking for low emitting/fuel-efficient vehicles as well as preferred
parking for carpools, which would encourage alternative transportation options. In order to
improve energy use, the project would exceed the standard California Title-24 Energy Code
by a minimum of 15 percent.

Page I iilobal Climate Chanfle
In 1988, the United Nations established the Intergovernmental Panel on Climate Change to
evaluate the impacts of global warming and to develop strategies that nations could
implement to curtail global climate change. In 1992, the United States joined other countries
around the world in signing the United Nations' Framework Convention on Climate Change
agreement with the goal of controlling greenhouse gas emissions, including methane. As a
result, the Climate Change Action Plan (CCAP) was developed to address the reduction of
greenhouse gases in the United States. The CCAP consists of more than 50 voluntary
programs. Additionally, the Montreal Protocol was originally signed in 1987 and
substantially amended in 1990 and 1992. The Montreal Protocol stipulates that the
production and consumption of compounds that deplete ozone in the stratosphere (i.e.,
chlorofluorocarbons, halons, carbon tetrachloride, and methyl chloroform) were to be phased
out by year 2000.
On June 1, 2005, the Governor of California signed Executive Order S-3-05, which
established the following greenhouse gas emission reduction targets for the State of
California:
. By 2010, reduce greenhouse gas emissions to 2000 levels;
. By 2020, reduce greenhouse gas emissions to 1990 levels; and
. By 2050, reduce greenhouse gas emissions to 80 percent below 1990 levels.
Executive Order '5-3-05 also recognized the importance of preparedness in that it directed the
Secretary of the California Environmental Protection Agency (CaIEPA) to lead an effort to
evaluate the impacts of climate change on California and to examine adaptation measures
that would best prepare the state to respond to the adverse consequences of climate change.
In response to S-3-05, the California Climate Action Team (CCAT) was convened, which
comprised of representatives from CalEPA, CARB, Integrated Waste Management,
California Energy Commission, and several other state departments. The CCA T prepared the
Climate Action Team Report to Governor Schwarzenegger and the Legislature (dated March
2006), which provides an overview of scientific evidence regarding climate change as well as
potential effects on California. The report also provides recommendations regarding
strategies the state should pursue to reduce climate change emissions.
In addition to Executive Order S-3-05, the California Legislature passed Assembly Bill 32
(Global Warming Solutions Act) (AB-32) on August 31, 2006. It requires the State's global
warming emissions to be reduced to 1990 levels by 2020. The reduction would be
accomplished through an enforceable statewide cap on global warming emissions that would
be phased in starting in 2012. Emission reductions shall include carbon sequestration projects
and best management practices that are technologically feasible and cost-effective.
However, AB-32 does not provide thresholds or methodologies for analyzing a project's
impacts regarding global climate change. AB-32 primarily provides a timeframe for
establishing plans, policies, and studies to address global climate change.

PageI\l7l1gnt ofJeglsfatlOn such as AB-32 and Execullve Order S-3-05, there has been much
debate regarding the analysis of global climate change in CEQA documents. As previously
mentioned, although several studies are available regarding the overall impacts associated
global climate change, the conclusions and predictions vary with each report. Based on the
current scientific literature, on a proposed project of this size, it would be speculative to
determine whether the contribution of any particular project or plans to greenhouse gas
emissions and climate changes are significant.
Based on an investigation of compliance with local air quality thresholds, future long-term
operational impacts, incorporation of Green House Gas Reduction measures, and consistency
the City's CO Reduction Program, the proposed project would still have the potential to
result in emissions associated with greenhouse gases. However, there is significant
uncertainty involved in making predictions of the extent of which the project operations have
on greenhouse gas emissions and global climate change. Therefore, a conclusion on the
significance of the environmental impact of climate change cannot be reached. Section
15145 of the CEQA Guidelines provides that, if after a thorough investigation a lead agency
frods that a particular impact is too speculative for evaluation, the agency should note its
conclusion and terminate discussion of the impacts.
Biolol!ical Resources
A Biological Resources Report and Impact Analysis was prepared by Dudek and Associates,
dated May 2007, to assess the potential direct, indirect, and cumulative impacts to sensitive
biological resources of the project. Biological surveys of the study area were conducted by
Dudek biologist Tricia Wotipka on June 28 and November 28, 2006, to map and assess the
existing vegetation and to conduct a general reconnaissance-level survey for plant and animal
species recognized as sensitive by local, state, or federal wildlife agencies and/or
environmental organizations. The results of the report are summarized below.
The approximate 26-acre project site (campus, borrow area, slopes and access roads) consists
of two altered or non-native habitat types: 24.15 acres of agriculture and 2.18 acres of
disturbed land. No natural vegetation communitieslhabitat types including jurisdictional
waters of the U.S.lState, including wetlands, were observed within the approximate 26-acre
study area. The proposed project is within a development area of a Covered Project as
identified in the City's MSCP Subarea Plan and as such has not been identified as a strategic
preserve area within the City nor is it located within a designated conservation area;
therefore, the proposed project would not impact the goals and objectives of the City's
MSCP Subarea Plan. Lands adjacent to the project site include developed lands to north
including Hunte Parkway and the Otay Ranch Village II SPA development, and
undeveloped former agricultural lands to the east, south and west. The City's MSCP Subarea
Preserve is located approximately 3,000 feet southeast of the project study area.
On June 28, 2006, and November 28, 2006, Dudek biologist Tricia L. Wotipka conducted a
general biological resources assessment of the approximately 26-acre study area, which
included a general wildlife and botanical survey, vegetation community mapping, and the

entire study area was walked to thoroughly complete the resource inventory.
Soils
According to Bowman (1973), the site supports two soil types within the Olivenhain series:
Olivenhain cobbly loam (OhC), 2 to 9 percent slopes and Olivenhain cobbly loam, 9 to 30
percent slopes. Soils in the Olivenhain series are typically characterized by well-drained,
moderately deep to deep cobbly loarns with a very cobbly clay subsoil (Bowman 1973). In
many places, microrelief of broad-base low hummocks, locally called mima mounds, may be
evident (Bowman 1973).
Botanv -Existing Plant Communities and Floral Diversitv
The majority of the site is in a highly disturbed state, which has been most likely affected by
previous grading, disking, ranching, and farming activities. No jurisdictional waters of the
U.S./State, including wetlands, under the jurisdiction of the U.S. Army Corps of Engineers
(ACOE), the Regional Water Quality Control Board (RWQCB), the CDFG, and the City's
Wetland Protection Prograrn (WPP) were identified within the 26-acre site. In accordance
with Table 5-3 of the City's MSCP Subarea Plan, the study area supports approximately
24.15 acres of agriculture and 2.18 acres of disturbed land. These vegetation
communities/land covers are graphically depicted in Figure 3 below; similarly, their acreages
are presented in Table 4.

These areas contain very few native shrubs and pastures are dominated by non-native
grasses, doveweed, and black mustard.
Within the study area, agricultural lands occupy a majority of the site (92 percent) and is
dominated by wild radish (Raphanus sativus), garland chrysanthemum (Chrysanthemum
coronarium), short-podded mustard (Hirschfeldia incana), black mustard (Brassica nigra),
ripgut brome (Bromus diandrus), and foxtail chess (Bromus madritensis).

Disturbed land refers to areas where persistent mechanical disturbance has resulted in
severely limited natural vegetation growth. Disturbed land can include dirt roads, abandoned
pads, unvegetated, manufactured slopes, and other man-made land covers. Within the study
area, disturbed land refers to the sparsely vegetated, 2:1 manufactured slope along Hunte
Parkway.
Implementation of the proposed project would result in direct, permanent impacts to
approximately 26 acres of non-native plant communitieslland covers, including 24.15 acres
of agriculture and 2.18 acres of disturbed land. Impacts to Tier IV habitat are not considered
significant in accordance with the City's MSCP Subarea Plan. Consequently, mitigation for
direct impacts to Tier IV habitat is not required.
Sensitive Biological Resources
Sensitive Vegetation Communities
No natural and/or sensitive vegetation communities, including wetlands and non-wetland
waters of the U.SJState, were identified within the 26-acre study area. Agriculture and
disturbed land are considered non-native Tier IV land covers in accordance with the City's
MSCP Subarea Plan and as such have very little to no biological value. The proposed project
would not result in direct impacts to sensitive vegetation communities and; therefore, impacts
are considered less than significant.
Sensitive Plants
No state- or federally-listed endangered or threatened species or species considered sensitive
by the California Native Plant Society (CNPS) were observed within the study area and due
to the extent of disturbance present, none are expected to occur. Therefore, direct impacts to
sensitive plant species are considered less than significant.
The City's MSCP Subarea Plan Preserve is located approximately 3,000 feet southeast of the
project study area. Although the City's MSCP Preserve is not immediately adjacent to the
project site, implementation of the proposed project has the potential to indirectly impact off-
site, native vegetation communities due to the introduction of invasive non-native species on
the project site. Implementation of the mitigation measures contained in Section F below
would reduce potential indirect impacts to adjacent biological resources to a level of less than
significant.
Sensitive Wildlife
No state- or federally-listed threatened or endangered animal species, or evidence of nesting
birds (i.e., nest building, territorial defense, transport of nesting material or food for young,
etc.) was identified during the spring general reconnaissance. Given the extent of disturbance

In addition, the study area has a moderate potential to provide foraging habitat for the
following avian species: white-tailed kite (Elan us leucurus), a USFWS Migratory Nongame
Birds of Management Concern (MNBMC), and the loggerhead shrike (Lanius ludovicianus),
a California Species of Concern (CSe). Implementation of the mitigation measures contained
in Section F below would reduce potential impacts to sensitive wildlife species to a level of
less than significant.
Habitat Linkal!es
Wildlife corridors are linear features that connect large patches of natural open space and
provide avenues for the immigration and emigration of animals. Salt Creek, which is located
off site approximately 3,000 feet southeast of the study area, is the only biological resource
in the project vicinity that may serve as a wildlife movement corridor. The study area itself is
not located within a movement corridor and is not expected to aid in the movement of
wildlife species because of its close proximity to other disturbed and developed sites. The
study area does not function as a habitat linkage or wildlife corridor; therefore, impacts are
considered less than significant. .
Regional Conservation - Cumulative Impacts
The cumulative assessment of biological resources impacts relies on the Chula Vista's
adopted MSCP Subarea Plan. Preservation of the region's biological resources is addressed
through the implementation of regional habitat plans. Impacts to biological resources in
Chula Vista are managed through the Chula Vista MSCP Subarea Plan, which incorporates
the Otay Ranch Resource Management Plan (RMP). Implementation of the City's MSCP
Subarea Plan contributes significant habitat conservation both within the Chula Vista
Subarea and within the Chula Vista MSCP Planning Area in the unincorporated County
Multi-Habitat Planning Area (MHP A).
The City's MSCP Subarea Plan designates the entire project area as a development area
within a Covered Project (i.e., Otay Ranch). A Covered Project refers to those projects within
Chula Vista for which hard-line Preserve boundaries have been established pursuant to the
Subarea Plan and where conservation measures consistent with the MSCP Subregional Plan
and the City's Subarea Plan have been or will be specified as binding conditions of approval
in the proposed project plans.
In addition to the City's MSCP Subarea Plan, the Otay Ranch area is governed by several
plarming documents that are relevant to biological resources within the study area. They
include the Otay Ranch General Development Plan! Subregional Plan (GDP/SRP) and the
Otay Ranch RMP. The Otay Ranch Resource Management Plan (RMP) further defines how
High Tech High University Park
Case Number: IS-07-014

Resolution No. 2007-300
Page 22>pen space is to be conserved and managed for biological resource value and constitutes the
California Environmental Quality Act (CEQA) mitigation for biological impacts associated
with development. Compliance relies on progressive acquisition of the designated Otay
Ranch Preserve areas to occur with each development approval.
In accordance with the City's MSCP Subarea Plan and Olay Ranch RMP, the proposed
project is considered a "corrunon use" facility. Common use areas include, but are not limited
to, local parks and public schools and are distinguished from other beneficial uses because of
their widespread benefit to the region. Pursuant to the Olay Ranch RMP, corrunon use areas
have been assumed with regards to preserve assembly and are not subject to conveyance
obligations pursuant to the OlaY Ranch RMP; therefore, the proposed project would not
impact the goals and objectives of the City's approved Subarea Plan and supporting Otay
RanchRMP.
A Statement of Overriding Considerations was adopted for the.Otay Ranch GDP in October
1993 that addressed impacts to biological resources, which included the loss of potential
foraging habitat within the development area of the proposed project. Thus, the loss of
potential foraging habitat within this area has been assumed, considered and approved
through the adoption of the Statement of Overriding Considerations (SOC) for the Otay
Ranch GDP. The construction of the proposed project would not result in any new significant
cumulative impacts that were not contemplated in the SOCs nor increase the severity of any
identified impacts in EIR 90-01.
Cultural! Paleontolo!!ical Resources
Cultural Resources
An archeological survey and significance evaluation of the project site (and adjacent borrow
area) was conducted by Brian F. Smith and Associates (Archeological Assessment for the
High Tech High Chula Vista Project. December 6, 2006, revised Aprilll, 2007). The results
of the archeological survey and significance evaluation are summarized below. A copy of the
archeological assessment is available for review at the City's Planning and Building
Department.
One previously unrecorded prehistoric site, SDI-18-136, was discovered during the
archeological survey. A testing program was conducted in order to determine the significance
of the newly discovered resource. The testing program sufficiently documented the resource,
consisting of a minimal marine shell scatter, and has subsequently exhausted any research
potential. Therefore, the significance evaluation conducted for SDI-18-136 determined that
the site is not significant according to criteria specified in State CEQA Guidelines, Section
15064.5. Impacts to this site resulting from project implementation would be considered less
than significant and no mitigation measures are required.
As noted in the archeological survey, a moderate potential still exists for additional
unrecorded sites to be discovered during initial grading operations. Therefore, to ensure that
impacts to potentially significant archeological resources are mitigated to less than

Page"~ficant, an archeological monitor shall be present during all cutting of previously
undisturbed soil. Implementation of the mitigation measures contained in Section F below
would reduce potential impacts to significant archeological resources to a level of less than
significant.
Paleontological Resources
In accordance with Appendix G of the CEQA Guidelines, impacts to paleontological
resources would be significant if the proposed project directly or indirectly destroys a unique
paleontological resource or site or unique geologic feature.
Grading for the proposed project would not impact any known paleontological resources;
however, grading activities have the potential to impact fossils that are potentially buried in
the underlying formations. The occurrence of fossils within the covered bedrock cannot be
evaluated prior to exposure. Areas of the Otay Formation with accumulations of colluvial
and alluvial deposits in the drainage course bottoms may be exposed during grading and
construction activities. The proposed grading of the Otay Formation sandstone would move
material with high sensitivity for paleontological resources. Exposure of these formations
could result in the unearthing of fossil remains, which could damage the fossils if they were
not recovered and salvaged. Destruction of the paleontological resources from these
formations would be a direct, potentially significant impact.
The mitigation measures contained in Section F below would mitigate potentially significant
impacts to paleontological resources below a level of significance.
Geolol!Y and Soils
In order to assess the potential geological and soils impact of the proposed project and the
associated off-site borrow area, a Geotechnical Investigation was prepared by GEOCON, Inc.
(Geotechnical Investigation, High Tech High Chula Vista, GEOCON Incorporated, February
13,2007). The results of this investigation are summarized below.
Soil conditions encountered during the geotechnical investigation included surficial deposits
comprised of compacted fill, topsoil, and colluvium. The geologic units include Tertiary-age
Otay Formation sandstone and mud stone members, Otay Formation bentonite member and
the Otay Formation gritstone member.
Soils
Development of the proposed project would result in a high school/middle school campus
with associated play yards, landscaping, parking, and access roads. Grading activities, which
remove the existing vegetative cover, would expose soils to runoff and erosion. The soils
contained in the project area have severe erosion susceptibility, resulting in a potentially
significant erosion impact. Construction on liquefiable soils within drainages could result in
injuries or loss of property during ground shaking of sufficient magnitude and duration.
Expansive soils within pavement, foundation, or slab sub grade could heave when wetted,
High Tech High University Park
Case Number: IS-07-014
Page 19
Resolution No. 2007-300 .
Page 24esulting in cracking or failure of these development Improvements. Development on
compressible soils could potentially settle under increased load and damage structures, roads,
and property.
Surficial soils (compacted fill, colluvium, and topsoil) are not considered suitable for the
support of fill or structural loads in their present condition. No additional soil or geologic
conditions were encountered or identified as part of the site-specific geotechnical
investigation that would preclude the development of the project as proposed, provided the
recommendations contained in the Geotechnical Investigation Report (Geotechnical
Investigation, High Tech High Chula Vista, GEOCON Incorporated, February 13, 2007) are
followed.
The potential discharge of silt during construction activities could result in siltation impacts
downstream. Appropriate erosion control measures would be identified in conjunction with
the preparation of final grading plans and would be implemented during construction. The
implementation of appropriate water quality best management practices (BMPs) during
construction would be required in accordance with the Chula Vista Standard Urban Storm
Water Mitigation Plan (SUSMP) and the City's Storm Water Management Standards
Manual. All portions of the development area disturbed during construction would either be
developed or would be appropriately landscaped in compliance with the Chula Vista
Municipal Code, Sections 19.36.090 and 19.36.110. Compliance with the above requirements
would be ensured by the City Engineer prior to the issuance of grading permits for the
proposed project and during construction. Therefore, the potential for the discharge of silt
into the drainage system would be less than significant.
Groundwater
Groundwater was not encountered during the geotechnical exploration of the site. Dependent
of the time of year grading is performed, perched water conditions may develop within the
westerly drainage possibly requiring some dewatering to facilitate removal of the colluvium.
A subsurface drainage system should be installed at the base of the canyon cleanout to
preclude the build up of water within fill materials. Groundwater is not expected to adversely
impact the development of the property as proposed, provided the recommendations
contained in the Geotechnical Investigation Report are followed.
Seismicity
Based on the Geotechnical reconnaissance, evidence obtained in the exploratory borings and
trenches, and a review of geologic maps, reports, and aerial photographs, the project site is
not located on any known active, potentially active, or inactive fault traces as defined by the
California Geological Survey (CGS). The CGS considers a fault seismically active when
evidence suggests seismic activity within the last 11,000 years. Based on a review of
available geologic data and published reports the project is not located within a State of
California Earthquake Fault Zone.
High Tech High University Park
Case Number: IS-07.0 14

~
Res9,!ution No. 2007-300
PageL!5 potentially active La Nacion Fault is located approximately 3 miles west of the project
site. The site could be subject to moderate to sever ground shaking in the event of a major
earthquake along this fault- However, as stated in the Geotechnical report, no geologic
conditions exist (including the La Nacion Fault) that would preclude the development of the
property provided that the recommendations of the Geotechnical investigation are
implemented. Therefore, impacts associated with seismicity/ground shaking are not expected
to adversely impact the development of the property as proposed, provided the
recommendations contained in the Geotechnical Investigation Report are followed.
Liquefaction
Liquefaction is generally limited to granular soil deposits located below the groundwater
table which are relatively loose, unconsolidated condition that are subjected to ground
accelerations from a large earthquake. Due to the dense nature of the underlying formational
soils, remedial grading recommendations and the lack of near-surface ground water table, the
potential for liquefaction at the site is considered less than significant.
Tsunamis, Seiches, and Earthquake-Induced Flooding
Tsunamis, seiches, and earthquake-induced flooding are not expected to occur on the project
site given its distance inland and elevation above the Otay Reservoirs.
A final soils report is required to be prepared to the satisfaction of the City Engineer, prior to
the issuance of grading and construction permits. Erosion control measures will be identified
in conjunction with the preparation of the grading plans and implemented during the
construction phase.
Implementation of project-specific design mltJgation measures as described in the
geotechnical investigation (Geotechnical Investigation, High Tech High Chula Vista,
GEOCON Incorporated, February 13,2007) would be required to reduce or avoid significant
impacts resulting from compressible and expansive soils. Potential impacts resulting from
geologic hazards would be reduced below a level of significance through implementation of
the project design recommendations contained in the Geotechnical investigation
(Geotechnical Investigation, High Tech High Chula Vista, GEOCON Incorporated, February
13, 2007), compliance with the City's Building Code, California State building codes (e.g.,
Title 24 of the California Code of Regulations, and the UBC), standard practices of the
Association of Structural Engineers of California, and the mitigation measures contained in
Section F below. These measures are included as a part of the Mitigation Measure
Monitoring and Reporting Program.
Hazards aod Hazardous Materials.
A Phase I Environmental Site Assessment (ESA) was prepared by Dudek and Associates
(dated May 2007) to assess the potential for hazardous materials to be located on the project
site. The Phase I ESA was prepared in accordance with the guidelines stipulated in the
High Tech High University Park
Case Number: IS-07-0l4
Page 21
Resolution No. 2007-300
Page 26American Society for Testing and Materials Standard E-1527-05. The results of the Phase I
ESA are summarized bellow. .
Information obtained during the Phase I ESA indicated that the project site and surrounding
areas have been used for dry farming and potentially irrigated farming, as well as cattle and
sheep grazing. Pesticides may have been used during agricultural activity on irrigated parts of
Otay Ranch after 1950. Previous environmental investigations on nearby portions of Otay
Ranch detected levels of arsenic and organochlorine pesticides that exceed the United States
Environmental Protection Agency's (USEPAs) preliminary remediation goals (PRGs). The
Phase I ESA prepared for the proposed project reveled no evidence or recognized
environmental conditions in connection with the project site except for the historical
agricultural activities. .
The results of the Phase I ESA could not confirm the use of pesticides on the project site and
associated borrow area and, therefore, recommended a Phase II ESA be conducted to further
evaluate the site for the presence of excessive levels of arsenic and organochlorine pesticides.
A Phase II ESA was prepared by Dudek and Associates (dated July 2007) to further assess
the potential for hazardous materials to be located on the project site. The results of the
Phase II ESA are summarized bellow.
As stated in the Phase II ESA, IS soil samples were collected at IS locations on the project
site (and associated borrow area) for arsenic and organochlorine pesticides analysis. The
results of the soil analysis indicated that the concentration levels for organochlorine
pesticides were less than CallEPA California Health Screening Levels (CHSLs).
Additionally, as stated in the Phase II ESA, three soil samples representing the highest
concentrations of organochlorine pesticides were also tested for organophosphorus
pesticides. The results of which indicated that the organophosphorus concentrations for all
three samples were below laboratory detection limits.
As previously stated, the soil samples were also analyzed for excessive levels arsenic. The
results indicated that, although the soil samples had detectible concentrations of arsenic, the
concentrations were within the range of naturally occurring arsenic concentrations in
Southern California including areas within the immediate vicinity of the project site. Based
on the results of the Phase II ESA, no further action is required; therefore, impacts associated
with hazardous materials are considered less than significant and no mitigation is required.
Hvdrolo~ and Water Quality
In order to assess potential impacts to Hydrology and Water Quality, a Preliminary Drainage
Study and Water Quality Technical Report were prepared by RBF Consulting August 10,
2007 and September 11, 2007, respectively. The results of those analyses are summarized
below.

Pagmting Conditions
The project site consists of undeveloped, former fannlands, with no eXlstmg drainage
improvements. Runoff from the undeveloped site currently drains to one of two tributary
canyons of Salt Creek. The existing receiving tributaries are devoid of vibrant vegetation and
generally devoid of dry weather runoff. The western portion of the project site, south of the
existing grading of Hunte Parkway, drains to a valley tributary of Salt Creek. This tributary
merges with Salt Creek just upstream of the confluence with Otay River. The eastern portion
of the project site drains to tributary of Salt Creek and then to a regional water quality basin
constructed as part of the Otay Ranch Village II SPA Plan development.
The most immediate receiving waters for the project site are the unnamed tributaries to Salt
Creek. Once flow reaches Salt Creek, the runoff progresses in a southerly direction to the
Otay River and then westerly, via the Otay River, to San Diego Bay. According to the
California 303(d) list published by the San Diego Regional Water Quality Control Board
(R WQCB Region 9), none of the receiving waters for the site are impaired for any pollutants.
Additionally, no Federal Emergency Management Agency (FEMA) Special Flood Hazard
Areas (SFHAs) have been mapped on the project site.
Hydrologic Effect of the Project
As stated in the preliminary drainage report, development of the project will increase
impervious areas and overall drainage area to the western receiving tributary. Based on the
preliminary site design, all runoff from the development footprint of the two schools would
discharge to the western tributary via storm drain conveyance system. Grading of the borrow
site located to the south and east of the site will be performed such that runoff from the
borrow area will maintain existing flow patterns.
To moderate the increase in flow resulting from site development, a detention basin has been
proposed within the multi-purposed field area. The detention basin has been designed to
attenuate the 2, 10, and lOO-year developed design flows to pre-development peak flows to
the western tributary. In addition, an energy dissipation devise will be installed at the
proposed storm drain outfall to reduce the effects of concentrated flows. Based on the results
ofthe preliminary drainage study, the hydrological effects of the project are concidered to be
less than significant.
On-Site Improvements
Permanent Treatment, Site Design, and Source Control BMPs shall be included as part of the
project in accordance with the City of Chula Vista SUSMP requirements and the Water
Quality Technical Report for the High Tech High (RBF Consulting, September 11,2007).
The facilities proposed to manage runoff and water quality from the site include, but are not
limited to: grading of pads to direct runoff away from structures, storm drain systems to
direct on-site runoff to appropriate outfall locations, rip rap systems, vegetated swales
(including use of the play field), detention basin, and sub-drains to be installed at all canyon
fill areas.

In accordance with the City's Standard Urban Stormwater Mitigation Plan (SUSMP) and
RWQCBs new NPDES permit adopted January 24, 2007, the project is also required to
implement Low Impact Development (LID) design features. Features included in the site
design to minimize the transfer to off-site facilities and maximize on-site treatment include,
but are not limited to, the following:
. Discharge of roof runoff to landscape areas and not directly to storm drains. This
includes minimizing the amount of roof gutters to reduce concentrated roof flows.
. Sheet flow of parking lot drainage to landscape areas to maximize contact with
landscaping before runoff enters the storm drains. This will result in increased
infiltration and treatment.
. Use of vegetated swales to convey runoff from parking areas. This will increase
infiltration and treatment of runoff before excess runoff enters storm drains.
. On-site detention facility and sheet flow of runoff across landscaped playing field
areas. Flow from the detention facility is regulated to attenuate the peak 100, 10, and
2-year flows to pre-development flow conditions.
. Use of decomposed granite for future pad areas of the Environmental Research
Center instead of concrete pavement in order to minimize the quantity of runoff from
the site.
Temporary Construction Improvements
Best Management Practices (BMPs) to prevent, reduce, or treat water pollutants will be
implemented during the constructing phase of the project and include, but are not limited to,
vegetation stabilization (hydroseeding), desilting basins, silt fencing, straw wattles, gravel
bags, storm drain inlet protection, construction ingress/egress stabilization, spill prevention
control, and employees and subcontractor training.
The project applicant shall obtain an NPDES Permit for Construction Activity from SWRCB.
Adherence to all conditions of the General Permit for Construction Activity is required. The
applicant shall be required under the SWRCB General Construction Permit to develop a
SWPPP and a Monitoring program Plan. The SWPPP shall specify both construction and
post-construction structural and non-structural pollution prevention measures. The SWPPP
shall also address operation and maintenance of post-construction pollution prevention
measures, including short-term and long-term funding sources and the party or parties that
will be responsible for the implementation of said measures.
In addition, the applicant must provide to the satisfaction of the City Engineer verification
that a complete and accurate Notice-of-Intent (NOn has been filed with the SWRCB. A
copy of the acknowledgement from the SWRCB that a NOI has been received for this project
shall be filed with the City ofChula Vista when received. Further, a copy of the completed

As a standard condition of approval, a final drainage study will be required in conjunction
with the preparation of the project grading plans. Properly designed drainage facilities will
be installed at the time of the site development to the satisfaction of the City Engineer. In
addition. compliance with required NPDES regulations and BMPs will reduce water quality
impacts to a less than significance level. These measures are included as a part of the
Mitigation Monitoring and Reporting Program (See Section F).
Noise
To assess the potential noise impacts of the project, an acoustical impact analysis was
prepared by RBF Consulting, Acoustical Assessment for the High Tech High University Park,
dated October 30, 2007 a copy of which is available for review at the Planning and Building
Department. The results of this analysis are summarized below.
Noise Standards
The acoustical analysis assessed the project with respect to the regulations contained in
Chapter 19.68, Performance Standards and Noise Control, of the Chula Vista Municipal
Code (noise control ordinance) and the noise element of the Chula Vista General Plan.
Pursuant to the noise control ordinance, no person shall operate, or cause to be operated, any
source of sound at any location within the city or allow the creation of any noise on property
owned, leased, occupied, or otherwise controlled by such person which exceeds the
established noise level limits (CVMC S 19.68.030(A)(4)). The noise level limits of the noise
control ordinance vary by receiving land use category and time of day (daytime versus
nighttime). Per Section 19.68.030 (B)( 4) of the noise control ordinance, if the ambient noise
level exceeds the established noise level limit, then the allowable noise exposure standard
shall be the ambient noise level. The existing and potential future noise-sensitive uses
adjacent to the project site potentially affected by project-generated noise consist of single-,
and multi-family residential units to the north.
For the evaluation of potential off-site receivers due to on-site noise sources, the City noise
ordinance allows the facility to make hourly average noise levels of up to 55 dBA Leq (60
dBA Leq for multi-family) or the ambient, whichever is higher, during the daytime hours at
the residential property line. When evaluating the potential noise impacts to on-site receivers
due to off-site sources (i.e., traffic), for this project the City has specified a land use
compatibility noise standard of 65 community noise equivalent level (CNEL) for on-site
outdoor use areas and 70 CNEL for the outdoor activity court (basketball court).
Existing Conditions
Ambient noise levels were measured during daytime hours at three locations in order to
ascertain the typical worst-case existing sound levels. The hourly average sound level (Leq)
recorded over the monitoring period ranged from 68.3 dBA Leq near the intersection of
High Tech High University Park
Case Number: /5-07-0/4
Page 25
Resolution No. 2007-300
Page 3<Plympic Parkway and Exploration Falls Drive to 46.9 dBA Leq near the intersection of
Hunte Parkway and Olympic Parkway. By comparison, the existing ambient noise
measurement collected at the project site was 47.5 dBA Leq.
On-Site Noise Levels
Phase I Development
Based on a review of the preliminary site plans for Phase I, the nearest on-site sensitive noise
receptors to Hunte Parkway include the out door activity court (basketball court) and north
facing building fa<;:ades. As stated in the acoustical assessment, noise levels (under full build
out conditions) noise levels at these locations would be approximately 65.3 dBA CNEL. As
previously stated, the applicable noise threshold for the basketball court area would be 70
dBA CNEL; therefore, noise levels at the basketball court would be consistent with the City
of Chula Vista noise standards and considered less than significant.
The north-facing building facades are also located within the 65 dBA CNEL noise contour
and as such would be subject to applicable requirements of the California Uniform Building
Code (UBC) that establishes a 45 dBA CNEL interior noise threshold for sensitive indoor
receptors. Standard construction practices typically provide an outdoor to indoor attenuation
rate of approximately 20 dBA. As previously discussed, the project would exceed the
standard California Title-24 Energy Code by a minimum of 15 percent. Therefore, interior
noise levels with buildings associated with Phase I development would be reduced to a level
of less than significant though the use of industry standard construction materials and
techniques consistent with the UBe. Compliance with UBC is required for all projects and is
verified through the City's development plan check process prior to issuance of building
permits.
Phase II Development
Preliminary site plans for Phase II are currently not available and the exact building locations
and sensitive outdoor uses such as play areas have not yet been determined. As indicated in
the analysis for Phase I, at 230 feet from the Hunte Parkway roadway centerline, noise levels
would be slightly above 65 dBA CNEL. Therefore, a potently significant impact would
occur if future buildings and/or outdoor use areas were proposed within 230 feet of the
roadway centerline. Prior to the issuance of building design permits for Phase II construction,
the applicant shall be required to prepare, to the satisfaction the Environmental Review
Coordinator, a subsequent acoustical assessment permits to ensure that sensitive outdoor uses
would not be exposed to noise levels exceeding 65 dBA CNEL. This mitigation measure is
included as a part of the Mitigation Monitoring and Reporting Program (See Section F).
Implementation of the mitigation measures contained in Section F of this MND would reduce
potential noise impacts to a level ofless than significant.

Resolution No. 2007-300
Pag&j~tionary Noise Sources
Potentially significant stationary noise sources associated with the school operations and
development activities consist of rooftop air conditioners (HV AC) or equipment and school
operations/activities. A summary of the analysis of estimated noise generated by these
stationary sources is as follows:
HV AC/Roof-mounted Equipment
The proposed project would require the use of heating, ventilation, and air conditioning units
(HV AC) at the school building, the location, type, number of units, and unit specifications of
which are currently not available. Noise levels from the mechanical equipment would be
minimized by orienting equipment away from any identified sensitive receptors, proper
selection of equipment, shielding, and proper installation. Impacts associated with roof
mounted HV AC equipment are anticipated to be less than significant. However, upon
completion of final site plans including mechanical design, the applicant shall be required to
submit a supplemental noise analyses and mechanical plans for each phase subject to review
the City Envirorunental Review Coordinator prior to issuance of building pennits for each
respective phase.
Upon review of supplemental noise analysis, if it is determined that there are potential noise
impacts created by the HV AC or other mechanical equipment, then applicable mitigation
measures shall be developed to ensure these impacts are reduced to a level of less than
significant. The applicant shall be required to be in compliance with applicable mitigation
measures identified in the updated noise analysis. This mitigation measure is included as a
part of the Mitigation Monitoring and Reporting Program (See Section F).
Public Address (PA) System and Bell Signal System
Typical noise sources generated from school facilities and sports events include public
address systems and bell signal systems that are essential to a school facility. The City of
Chula Vista Noise Ordinance, Section 19.68.050, regulates these signaling devices. Limiting
the operation cycle or sounding of these devices to no more than two minutes continually in
any 60-rninute period or intermittent sounding over a five-minute period in any hour.
Currently, the project proposal does not include the use ofPA and/or bell system. However,
in the event that such a system is proposed, the applicant shall be required to submit a
supplemental noise analysis based on final site designs and to the satisfaction of the
Environmental Review Coordinator, to verify conformance with Chula Vista Noise
Ordinance, Section 19.68.050.
Upon review of supplemental noise analysis, if it is determined that there are potential noise
impacts created by the P A system or bell signal system, then applicable mitigation measures
shall be developed to ensure these impacts are lessened to a level of less than significant.
The applicant shall be required to be in compliance with applicable mitigation measures
identi fied in the updated noise analysis. This mitigation measure is contained in Section F
below.

School Operations/Activities
The acoustical assessment prepared by RBF also included an evaluation of other potential
noise generating operations andlor activates including routine landscape maintenance,
ancillary activities (outdoor activity court, pre-school, adult education, etc.), and parking lot
activities (parking lot traffic, car door slamming, conversations). As detailed in the acoustical
assessment, noise associated with operational activities would not exceed the City's
applicable noise standards; therefore, impacts associated with school operations/activities are
considered less than significant.
Short-term Construction Activities
A variety of noise-generating equipment would be used during the construction phase of the
project. Construction equipment utilized during development may include scrapers dump
trucks, loaders, jackhammers, and concrete mixers, along with others.
Construction activities are exempt from the exterior noise standards specified in Chapter
19.68 as discussed in Section 19.68.060 of the City's Municipal Code. However,
construction noise has the potential to be a nuisance in existing residential areas in the
vicinity of the project site. Pursuant to the Chula Vista Municipal Code Section 17.24.050
(Paragraph J), construction is prohibited Monday through Friday from 10:00 P.M. to 7:00
A.M., and from 10:00 P.M. to 8:00 A.M. on Saturdays and Sundays. Compliance with this
regulation will ensure that construction noise does not cause a significant nuisance noise
impact.
Although construction noise is exempt from the levels specified in Section 19.68.040,
potential construction noise levels were estimated for assessment of potential impacts to on-
site receivers (e.g., classrooms) during the development of Phase II. Cumulative worst-case
levels associated with construction equipment were calculated for the closest sensitive on-site
receptors (i.e., classrooms/school buildings) during the construction of Phase II. The City
does not have fixed operation standards for these types of construction activities, however,
assessment is discussed below.
Noise produced by construction equipment varies substantially, depending upon the type of
equipment being used and its operation and maintenance. Construction noise is generally of
relatively short duration, lasting from a few days to a period of months. Noise impacts
associated with construction activities would typically occur in several distinct phases, each
with its own noise characteristics. The first phase, site preparation, is generally the noisiest
and has the shortest duration. Activities that occur during this phase include earth-moving
and compacting of soils. High noise levels are created during this phase from the operation
of heavy-duty trucks, backhoes, and front-end loaders. The majority of this type of
construction wiIl occur during the development of Phase 1.

Case Number: /S-07-014

Resolution No. 2007-300
Pagt-Sjtated III the acoustical impact report, a reasonable worst-case evaluation assumed that the
three loudest pieces of equipment would operate simultaneously and continuously over at
least one hour within a focused area of 15 yards of each other. The combined sound level of
three of the loudest pieces of equipment (scraper, bulldozer, and heavy truck) is 92 dBA
measured at 50 feet from the noise source. These estimations of noise levels take into account
distance to receptor attenuation, attenuation from molecular absorption, and anomalous
excess attenuation.
Construction activities associated with Phase II development has the potential to adversely
affect noise-sensitive uses such as classrooms and other school buildings. As such, these
noise levels are considered to represent a potentially significant impact. Although the City
does not regulate construction noise during the day it should be noted that if noise levels are
found to be excessive enough to disrupt classroom activities, or impact students or teachers
in the classrooms, onsite temporary noise barriers or other noise abatement measures shall be
implemented on a case-by-case basis to provide adequate attenuation to the affected phased
areas.
The project would be required to limit construction hours, place muffiers on equipment
engines, and orient stationary sources to direct noise away from sensitive uses. These
measures are included as a part of the Mitigation Monitoring and Reporting Program (See
Section F). Thus, construction-related impacts would be less than significant.
Transportationrrraffic
A Traffic Impact Analysis was prepared by Rick Engineering Company (dated May I, 2007)
in order to identify potential traffic impacts associated with the development of the proposed
project. The results of the traffic impact analysis are summarized below.
Intersection and Roadwav Segment Analvsis Methodologv
The project driveways, nearby intersections and roadways were analyzed under the following
scenanos:
.
Near Term (2010) No Project
Near Term (2010) with Phase I Project .
Near Term (2010) with Phase 1 + Phase II Project
Long Term (2030) No Project

The level of service for roadway operations was calculated based on the City's Average
Daily Trip Table for each roadway classification (Table B-1, Page 6 of the City ofChula Vita
Traffic Impact Study Manual).
The level of signalized intersections was calculated using the methodologies described in
Chapter 16 of the 2000 Highway Capacity Manual (HCM). The level if service for signalized
intersections is defined in terms of average control delay, which is made up of a number of

signalized intersection analysis also takes into account intersection spacing and coordination.
The cycle lengths were optimized to complete the intersection LOS analysis.
Significance Criteria
The City's "Guidelines for Traffic Impact Studies" was utilized for the basis of determining
potential impacts, both project specific or cumulative, to freeway segments, roadway
segments, and intersections.
Existing Conditions
The project site is located on the south side of Hunte Parkway, east of the future extension of
Discovery Falls Drive. Public access to the site will be provided via one driveway off of the
future extension of Discovery Falls Drive. A dedicated emergency access will be provided
off of Hunte Parkway. Currently, all roadway segments and intersections within the study
area operate at an acceptable level of service in accordance with City threshold standards.
Proiect Trip Generation
Phase I of the project would generate 1,100 daily trips with 220 (154 inbound and 66
outbound) trips during the a.m. peak-hour and 110 (44 inbound and 66 outbound) trips during
p.m. peak-hour. The Phase n portion of the project would generate 1,331 daily trips with 416
(250 inbound and 166 outbound) trips during the a.m. peak-hour and 120 (48 inbound and 72
outbound) trips during p.m. peak-hour. The entire project (phase I + Phase ll) would generate
a total of 2,431 daily trips with 636 (404 inbound and 232 outbound) trips during the a.m.
peak-hour and 230 (92 inbound and 138 outbound) trips during p.m. peak-hour.
Near Term (2010) Condition
Based on the information provided in the draft SUHSD Middle School12/High School 14
traffic impact study prepared by Katz, Okitsu and Associates dated October 2006, turning
movement volumes at some of the study intersections (common intersections with Katz,
Okitsu and Associates traffic study) for Near-Term (2010) Condition were formulated. The
turning movement volumes at the remaining study intersections were based on a comparison
of traffic forecasts from the City's tollway model and traffic forecasts obtained from
Linscott, Law and Greenspan Engineers staff for a freeway. Traffic volumes were
reduced/adjusted to represent future forecasts for the toll condition at the remaining
intersections.
Based on the modeling results for Near-Term (2010) No Project conditions, all of the study
intersections and roadway segments are expected to operate at acceptable levels of service.
Under Near-Term (2010) + Phase I Project Conditions, significant impacts would occur
without improvements to the intersection of Discovery Falls Drive at Hunte Parkway. The

level ofless than significant:
.
Installation of fully activated traffic signals at the intersection of Hunte Parkway at
Discovery Falls.
Install a westbound left turn pocket on Hunte Parkway at Discovery Falls
Install a northbound left turn pocket on Discovery Falls at Hunte Parkway
Install a southbound left turn pocket on Discovery Falls at the Project Driveway
Install a one lane inbound and two lanes outbound at the Project Driveway
.
.
.
.
Similarly, potentially significant impacts associated with Near-Term (2010) with Phase I plus
Phase II Project Condition traffic would be mitigated to less than significant with
implementation ofthe following street improvements:
. . Install an eastbound right turn pocket on Hunte Parkway at Discovery Falls
. Install one additional lane inbound to have two lanes inbound and two lanes outbound
at the Project Driveway
Long Term (2030) Condition
Based on the modeling results for Long-Term (2030) No Project Condition, all of the study
intersections and roadway segments are expected to operate at acceptable levels of service.
With implementation of the traffic control measures described above, all of the study
intersections and the roadway segments are expected to operate at acceptable levels of
service under Long-Term (2030) plus Project (Phase I + Phase II) Condition.
The mitigation measures described in Section F below would mitigate traffic impacts to a
level ofless than significant.
Proiect Site Access and Circulation
Access to the project will be provided via two access points: a full access driveway that
would connect with the south leg of the Hunte ParkwaylDiscovery Falls intersection
providing full access; and an Emergency Vehicle only access driveway on Hunte Parkway.
The project driveway on Discovery Falls will form a Tee-intersection with Discovery Falls.
Discovery Falls will not be open for traffic operations south of the project driveway under
Near-Term Conditions; therefore, only two turning movements will be provided under near-
term project conditions: Inbound project vehicles turning left into the project driveway from
southbound Discovery Falls; and the outbound project vehicles turning right onto northbound
Discovery Falls from the project driveway. These two movements will be non-conflicting
and do not need traffic controL These two movements will occur simultaneously resulting in
reduced stacking of vehicles at the project access. Under long -term conditions, Discovery
Falls is expected to be open for traffic operations south of the Project Driveway. An all-way

mtersectlOn.
At the intersection of Discovery Falls and the Project Driveway, two right turn lanes are
required to sufficiently accommodate the project vehicles turning right onto northbound
Discovery Falls for Phase I buildout. The southbound Discovery Falls approach at this
intersection would be provided with one lane striped as a left turn only lane to accommodate
the project vehicles turning left into the driveway with one receiving lane on the project
driveway under Phase I buildout. An additional left turn lane will be provided along
southbound Discovery Falls approach at this intersection with an additional receiving lane on
the project driveway to accommodate the increased number of project vehicles with Phase II
buildout.
At the intersection of Hunte Parkway and Discovery Falls, there would be a considerable
number of project vehicles (335 vehicles during the AM peak) turning right onto southbound
Discovery Falls from eastbound Hunte Parkway during the school peak hours. The
intersection level of service calculations show that the intersection of Hunte Parkway and
Discovery Falls is expected to operate acceptably under Near-Term (2010) with Phase I plus
Phase II Project and Long-Term (2030) with Project Conditions. However, to reduce the
potential queuing issues, an exclusive right turn lane for the eastbound Hunte Parkway
approach would be required. In addition, overlap phasing for the eastbound right turn
movements are also required to allow for simulations movement to occur with the
northbound left turn movement, thereby reducing potential queuing impacts for the
eastbound right turn movement.
Drop-offIPick-up Areas
Based on the proposed site plan, there is a drop-offlpick-up area located on the eastern side
of the project site. This drop-offi'pick-up area would take access from the driveway at
Discovery Falls. The project traffic in the drop-off7pick-up area will circulate in a one-way
counterclockwise fashion in which cars park curbside to drop-off students. Based on the
preliminary site plan, the one-way circular travel way has a total width of 30 feet with
approximately 200 feet of storage. Additionally, a 10-foot wide passenger drop off/pick up
lane and a 20-foot travel way, which includes a fire lane, is provided. Parking should be
prohibited within the inside curb lane of the travel way to allow for fire/emergency vehicle
access. An attendant should be present during the peak drop-off /pick-up periods to keep
circulation flowing in a safe marmer and to ensure fire/emergency lane is not constricted or
blocked. Lastly, to discourage mid-block pedestrian crossing on Discovery Falls, parking and
stopping must be prohibited on both sides of Discovery Falls and Hunte Parkway in the
vicinity of the project site.
The mitigation measures contained in Section F below would mitigate potential impacts to
queuing and pedestrian safety to a level of less than significance. These measures are
included as a part of the Mitigation Monitoring and Reporting Program.

5. Prior to issuance of land development permits, including clearing or grubbing and
grading permits, the applicant shall incorporate into grading plans to the satisfaction of
the City Engineer and Environmental Review Coordinator, the following:
"Prior to issuance of any grading permits, the applicant shall confirm to the City of
Chula Vista that a qualified paleontologist has been retained to cany out the following
mitigation program. The paleontologist shall attend pregrade meetings to consult with
grading and excavation contractors. (A qualified paleontologist is defined as an
individual with a M.S. or Ph.D. in paleontology or geology who is familiar with
paleontological procedures and techniques.)
A paleon/ological monitor shall be on-site at all times during the original cutting of
previously undisturbed sediments of highly sensitive geologic formations (Otay
Formations) to inspect cuts for contained fossils. The paleontological monitor shall work
under the direction of a qualified paleontologist. (A paleontological monitor is defined
as an individual who has experience in the col/ection and salvage offossil materials.)
In the event that fossils are discovered in unknown sensitive formations, it may be
necessary to increase the per-day field monitoring time. Conversely, if fossils are not
discovered, the monitoring should be reduced.
When fossils are discovered. the paleontologist (or paleontological monitor) shall
recover them. In instances where recovery requires an extended salvage time, the
paleontologist (or paleontological monitor) shall be allowed to temporarily direct, divert,
or halt grading to allow recovery offossil remains in a timely manner. Where deemed
appropriate by the paleontologist (or paleontological monitor), a screen-washing
operation for small fossil remains shall be set up.
Prepared fossils, along with copies of all pertinent field notes, photographs, and maps,
shall be deposited (with the applicant's permission) in a scientific institution with
paleontological collections such as the San Diego Natural History Museum. A final
summary report shall be completed which outlines the results of the mitigation program.
This report shall include discussion of the methods used, stratigraphy exposed, fossils
collected. and significance of recovered fossils. "

Resolution No. 2007-300
Page 41 documents to the satisfaction of the City Engineer. Recommendations to be implemented
include, but are not limited to:
. Grading plans shall indicate that excavations within the sandstone-mudstone
member of the Otay Formation will encounter bentonite layer or zones with
bentonite rich materials. These materials are highly expansive and should be
placed in deeper fill areas and a least 10 feet below proposed finish grade
elevations.
Grading plans shall indicate that cut pads that expose claystone or bentonite
materials should be under cut to completely remove the expansive soils. If the
bentonite or claystone layers are relatively thin and can be completely removed
in the upper I to 3 feet, then the depth of undercut should be at least 3 feet.
Where expansive materials extend deeper that 3 feet, the undercuts should be at
least 5 feet below proposed finish pad grade elevations. After the over-
excavations have been performed, the area should be brought back to design
subgrade elevations with properly compacted low expansive granular soils.
Grading plans shall indicate that, in order to reduce the potential for differential
settlement, the cut portion of cut-fill transition pad (future ERe Finish Floor
547) should be undercut to a depth of at least 3 feet and replaced with
compacted, low expansive (El less that 50) fill soils. The main high school
building, approximately 425 feet in length, will be underlain by approximately 0
to 70 feet of fill. The cut portion of this building should be undercut at least 5
feet at the north end (FF 547) and the undercut should be increased to 10 feet at
a distance of approximately 75 feet from the north end (FF 548). Over-
excavations should be cut at a gradient of I percent toward the street or toward
the deepest fill area to provide drainage for moisture along the contact between
formational material and compacted fill.
Grading plans shall indicate that, where practical, the upper 3 feet of building
pads (cut or fill) and 12 inches in pavement areas should consist off properly
compacted low (EI less that 50) expansive granular soils. Highly expansive
material should be placed in deeper fill areas and properly compacted.
Grading and building plans shall indicate that under no circumstances should
water be allowed to pond adjacent to footings. The building pads should be
properly finish graded after the buildings and other improvements are in place
so that drainage water is directed away from foundations, pavements, concrete
slabs, and slope tops to controlled drainage devices.
Landscape Plans shall incorporate drought-tolerant vegetation having variable
root depths and requiring minimal landscape irrigation along all slope areas.
