also be installed to vent exhaust fumes from the engine bays, An emergency generator and two above
ground fuel tanks enclosed within a masonry structure are proposed along the southern property
boundary ,
The living quarters will accommodate 10 personnel to staff a 3-person engine company, a 4-person
truck company, a future Battalion Chief, and possibly a two-person ambulance company, The station
will include office space for the Fire Prevention Division as well as for Police Department use,
Approximately twenty-seven on site parking spaces are proposed, including handicapped spaces,
Grading for the construction of Street "A" will result in a cut slope along the north side of the
roadway ranging in height from 35 feet near La Media Road to 60 feet at the present terminus of
Street "A" near the Village Two High School site, The cut slope along the south site of the roadway
w¡]] range from two fcct near the fire station to 20 feet in height near the Village Two High School
site.
C Compliance with Zoning and Plans
The proposed firc station is includcd in the Otay Ranch General Development Plan (GDP) as a
necessary public facility, The station is included in the adopted GDP Village Two Land Use Plan;
thus, the construction of the station is compatible with the Chula Vista General Plan and Otay Ranch
GDP, A redesignation of the site from Planned Community (PC) zone to Public/Quasi-Public (P-Q)
zone is proposed to allow for a public use within Village Two prior to the processing of the SPA plan.
Construction of the proposed fire station would conform to the City's environmental plans and
polices, Development of the project site was anticipated as a part of the GDP and the Otay Ranch
Resource Management Plan (RMP) and the Phasc 2 RMP, The f;re station would not affect
agricultural resources, The majority of the site has been graded as a part of the construction of
Olympic Parkway, No agricultural activities occur on the project site,
D, Public Comments
On May I, 2002 a Notice of Initial Study was circulated to property owners within a 500-foot radius
of the proposed project site, The public review period ended May 13,2002, One comment letter was
received hom the Otay Water DIstrict This commcnt letter recommended that the City coordinate
with the DIstrict throughout the planning process,
E IdentificatIon or Environmcntal Effects
An Initial Study conducted by the City of ChuJa Vista (including the attached Environmental
Checklist fonn) detcnnined that although the proposed project could have a significant environmental
effect, there wIll not be a sIgnificant effect in this case because mitigation measures described in
Section F below have been added to the project The preparation of an Environmental Impact Report
wIll not be required, This Mitigated Negative Declaration has been prepared in accordance with
Scction 15070 of the State CEQA Guidelines,
1. Geophysical alld \Vater
Although construction grading for Street "A" and the proposed fire station will be performed in
compliancc with the City of Chula Vista Grading Ordinance (Ordinance 1797, as amended),
significant water quality impacts could occur during the construction period due to disruptions of
the soiL Following construction of the fjre station significant water quality impacts could result
from runoff that includes sedimentation, hydrocarbons, nutrients, pesticides, and debris,
2 06107/02
2. Air Quality
The proposed project would generate sufficient emissions and dust during construction-re1ated
activities to result in a short-term significant, but mitigable, impacts to air quality, Although air
quality impacts resulting from construction related emissions are potentially significant, they are
considered short-term in duration since construction is a relatively short-term, one-time activity,
Dust control during grading operations would be regulated in accordance with City of Chula
Vista grading standards and the rules and regulations of the San Diego Air Pollution Control
District (APCD}
3. Hazards
The proposed fire station site will include above ground storage tanks (1,000 gl. of diesel and 500
gl. of gasoJine) for operation of the emergency generator and fire engines, Emergency shutoff
switches and a fire suppression system will be installed. Potentially significant hazard impacts
could occur if a leak occurred in either of the fuel tanks
4. Noise
The emergency generator may produce a noise level or 85 dB at 80 fcet without noise attenuation,
111e generator would be operated during power outages and for monthly testing, Monthly testing
is nonnally conducted on Saturdays, The Village Two multi-family residential units planned for
constTUction to the south and west of the proposed fire station could be significantly impacted by
the emergency generator noise even though a six- foot high wall is also proposed to be constructed
along the proposed tire station's southem and wcstem site boundary,
S. Paleontological Resources
Previous grading in the Otay Ranch area has uncovered a wide variety of fossil remains and there
is a pOSSIbility that fossils may be uncovered during the cut grading for the extension of Street
"A" Potentially significant paleontological resource impacts could occur if fossils are uncovered
during the grading operation,
F, Mitigation Necessary to A void Significant Impacts
Project-specific mitigation measures arc required to reduce potential environmental impacts identified
in the Initial Study to a less than significant level. The mitigation measures will be made a condition
of approval, as well as requirements of the attached Mitigation Monitoring Reporting Program
(Attachmcnt "A"),
Geophysical & Water
Erosion and Sedimentation
---
I. Prior to the issuance of a grading permit, a water quality report shall be submitted to the City
Engmeering Department that addresses all appJicable regulations established by the V,S,
Environmental Protection Agency (USEPA) as set forth in the Natural Pollutant Discharge
Ellmmation System (NPDES) pennit requirements for urban runoff and stonn water discharge
and any rcgulations adopted by the CIty of Chula Vista pursuant to the NPDES regulations or
requlremcnts. Thc site-specIfic water quality report will address pollutants of concem and
implemcntatlon or Best Management PractIces (I3MPs), This study will to ensure that
3 06/07/02
pollutants and runoff from the project will be reduced to the maximum extent practicable
(MEP). Implementation of the recommended BMPs during and after construction would
reduce erosion and sedimentation in the downstream storm drain system to a less than
significant leveL The recommendations of the approved water quality report will be adopted
as requirements of the proposed project
2, The National Pollutant Discharge Elimination Systems (NPDES) Permit Order No, 2001-01 and
Best Management Practices (BMPs) are required to be implemented during and after construction
to prevent sedimentation and other pollutants from entering the storm drain system, Short-term
construction erosion would be reduced to a less than significant level by the installation of
temporary de silting and erosion control devices, These devices include de silting basins, berms,
hay bales, silt fences, dikes, and shoring, Pollutants resulting from the use of the site as a fire
station shall be reduced to a less than s1gnificant level through the installation of a flow-based
catch basin and/or gross pollutant traps that capture and retain floatable, trash, debris, and fine
sand,
Air Quality
Construction Related Emissions
}, All unpaved construction areas shaH be sprinkled with water or other acceptable dust control
agents during dust-generating activities to reduce dust emissions, Additional watering or dust
control agents shall be applied during dry weather or windy days until dust emissions are not
visible,
4, Trucks hauling dirt and debris shall bc properly covered to reduce windblown dust and spills,
5, A 20-mile-per-hour speed limit on unpaved surfaces in connection with the project shall be
enforced,
6, On dry days, dirt and debris spilled onto paved surfaces shall be swept up immcdiately to reduce
fe-suspension of particulate maller caused by vehicle movement. Approach routes to
construction sites shall be cleaned daily of construction-related dirt in dry weatheL
7, On-site stockpiles of excavated material shall be covered or watered,
8, Disturbed areas shall be hydroseeded, landscaped, or developed as quickly as possible and as
directed by the City to reduce dust generation,
9, lleavy-duty construction equipment with modified combustion/fuel injection systems for
emissions control shall be utilized during grading and construction activities, Catalytic reduction
for gasoline-powered cquipment shall be used, A1so, construction equipment shall be equipped
with prcehambcr diese! engines (or equivalent) together with proper maintenance
Hazards
Fuel Leaks
10, The above ground fuel tanks shall be of double wan construction,
4 06/07/02
11, The above ground fuel tanks shall be constructed within a containment basin having a
capacity of 150% of the fuel tank capacity,
Noise
Emergency Generator
12, The emergency generator shall be enclosed in a masonry structure capable ofreducing
generator noise to 45 dB (A) at all property lines.
Paleontological Resonrces
Gut Grading
13, A qualified a paleontologist will be retained to implement a paleontological monitoring
and recovery program as a condition of the project construction contract A qualified
paleontologist is defined as an individual with and MS or PhD, in paleontology or
geology that is a recognized expert in the identification and recovery of fossil materials,
14, The qualified paleontologist will attend the project pre-construction meeting to discuss
project-grading plans with the project contractor(s), If the qualified paleontologist
detcn11ines that proposed excavation/grading will likely cut into undisturbed portions of
the underlying geologic formation, then monitoring will be conducted as outlined below,
15, The project paleontologist or a paleontological monitor will be on-site during original
cutting of the underlying geologic formation, A paleontological monitor is defined as an
individual who has experiencc in collection and salvage of fossil materials, and who is
working under the direction of a qualified paleontologist. Monitoring of the noted
geologic units will be at least half time at the beginning of excavation, and will be either
increased or decreased depending on initial results (per direction by the project
paleontologist)
16, In the event that well-preserved fossils are discovered, the project paleontologist will
havc the authority to temporarily halt or rcdirect construction activities in the discovery
area to allow recovery in a timely manner (typically on the order of 1 hour to 2 days), All
collected fossil remains will be cleaned, sorted and catalogued, and deposited in an
appropriated scientific institution such as the San Diego Muscum of Natural History,
17, A report (with a map showing fossil site locations) summarizing the result, analyses and
conclusions of the above described monitoring/recovery program will be submitted to the
City of Chula Vista Planning Departmcnt within three months of terminating monitoring
activities,

determined that the site is suitable for development A nine-foot high fill slope created for the
construction of La Media Road will be located at the eastern edge of the site, A 13-foot high fill slope
will be located immediately off-site to the west to create the level building pad, Grading for the proposed
fire station will generate 119,454 cubic yards (c,y,) of cut material; 20,134 cf will be placed on site as
fill material, and 99,320 c,y, will be exported to the Village Two borrow site or to Otay Ranch Village
Six, which is located east of Village Two, across La Media Road, In Village Six the export material
would be used to create building pads,
Compliance with the building design and construction requirements of the Uniform Building Code
requirements would avoid potentially significant structural impacts resulting from seismic activity, City
of Chula Vista standard engineering conditions require that improvement plans be based on a site-specific
geotechnical/soils study submitted concurrently with the first set of grading plans, Recommendations
included in the geotechnical study will reflect site-specific soil conditions as determined by borings and
trenches, erosion potential during and after construction, soil permeability and infiltration, and corrosivity
testing, The grading recommendations will specifically address undocumented till, bentonite, landslide
debris, kelp by-products, and groundwateL No significant geologic effects are anticipated to result from
construction of the proposed project

Grading for the construction of Street" A" will result in a cut slope along the north side of the roadway
ranging in height from 35 feet near La Media Road to 60 feet at the present terminus of Street "A" near
the Village Two High School site, The cut slope along the south site of the roadway will range from two
feet near the proposed project to 20 feet in height near the Village Two High School site, The cut slopes
required for the construction of Street "A" would be temporary slopes until such time as grading for the
construction of Village Two occurs, The slopes will be planted as required by the City of Chula Vista
Grading Ordinance (Ordinance 1797, as amended) to prevent erosion and downstream water quality
impacts, The final configuration, and landscaping, of these temporary slopes will be determined when
grading plans for Village Two are completed.
The U,S, Department of Agriculture Soil Survey identifies the soils at the project site as Diablo clay, 9-
IS percent slope (DaD), which are classified as Hydrologic Group D. Diablo clay soils are rated as
having a high runoff potential and moderate erosion potentiaL Water quality pollutants commonly found
in urban runoff include: sediment discharge due to construction activities and post-construction areas left
bare; nutrients from fertilizers; trash and debris deposited in drain inlets; hydrocarbons from paved areas;
and pesticides from landscaping.
Although construction grading for Street "A" and the proposed fire station will be performed in
compliance with the City ofChula Vista Grading Ordinance (Ordinance 1797, as amended). significant
water quality impacts could occur during the construction period due to disruptions of the soiL Following

Comments: The proposed project site is not located in a mapped t100d zone and no significant t100d
impacts would result from developing the site, As shown on the preliminary grading plan, brow ditches
around the south and west boundaries of the site will divert runoff from the adjacent multi-family
residential area around the proposed project site, An onsite storm drain system, including a t1ow-based
catch basin will convey onsite runoff to the Street" A" storm drain. This storm drain will connect to the
storm drain in La Media Road and Olympic Parkway, No "wet" training drills will be conducted at the
proposed fire station that would result in a discharge of pollutants into the storm drain system,
The City Engineering Division has reviewed and concurs with the results of a preliminary drainage
analysis completed for the project A condition of project approval will require that onsite drainage
facilities be included in the first submittal of grading and improvement plans, Additional detailed
drainage studies will be prepared concurrently with the final grading plans for the project as required by
the Grading Ordinance,
All grading operations will be performed in compliance with the City of Chula Vista Grading Ordinance
(Ordinance 1797, as amended), The onsite parking area is classitïed as a Priority Development Project
by Section F I ,b(2)(a)viii of the National Pollution Discharge Elimination System (NPDES) Permit,
Order No, 20-11-0 L This classification requires compliance with the Standard Urban Storm Water
Mitigation Plans (SUSMPs) and Numeric Sizing Criteria of the Permit A site-specific water quality
report that addresses pollutants of concern and implementation of Best Management Practices (BMPs) will
be prepared and approved by the City prior to the issuance of a grading permit This study will ensure
that pollutants and runoff from the project will be reduced to the maximum extent practicable (MEP),
Implementation of the recommended BMPs during and after construction would reduce erosion and
sedimentation in the downstream storm drain system to a less than significant leveL
Short-term erosion impacts would be reduced to a less than significant level by the installation of
tcmporary desilting and erosion control devices required by the NPDES Permit, and specitied on the
grading and improvement plans ilL These devices include desilting basins, berms, hay bales, silt fences,
dikes, and shoring, Potentially significant long-term water quality impacts could result from runoff
carrying sediments, hydrocarbons, nutrients, pesticides, and debris, These long-term impacts would be
reduced to a less than significant level by the implementation of BMPs as specified in the NPDES Permit
The geophysical mitigation measures included in Section XIX will assure that the NPDES Permit
requirements and BMPs are implemented,
Adequate public water service is available to the site, Groundwater would not be impacted because there
would be no additions or withdrawals from the local aquifer-
Mitigation: Geophysical mitigation measures #1 and #2 listed in Section XIX would reduce short-term
and long-term water quality impacts to a less than significant leveL

Comments: Engine combustion emissions and dust generated during construction-related activities could
potentially result in short-term significant, but mitigable, impacts to air quality, Fugitive dust would also
be created as a result of clearing, earth movement, and travel on unpaved surfaces. Although air quality
impacts resulting from construction-related emissions may be potentially significant, these emissions are
considered short-term in duration since construction is a relatively short-term, one-time activity. Dust
control during grading operations would be regulated in accordance with the rules and regulations of the
San Diego Air Pollution Control District (APCD), During construction of the proposed project, the
project will be suhject to mitigation measures outlined helow in Section XIX,
A vehicle exhaust extraction system would be installed in the proposed fire station to vent fire engine
exhaust from the equipment bays, The design of the exhaust system is the same as the system used in the
existing tire stations; the proposed vent system will disperse all exhaust so as to prevent it from adversely
affecting adjacent land uses, The proposed fire station is consistent with the General Plan land use
designations that were used for the Regional Air Quality ModeL Emissions from traffic associated with
the proposed fire station will be less than significant because they would be consistent with the emission
projections included in the Regional Air Quality ModeL No sensitive receptors would be located in the
adjacent areas, No significant long-term air quality impacts are expected to result

Comments: Street "A" (Santa Venetia) and La Media Road will be constructed prior to the completion
of the proposed fire station, La Media Road is classified as a 6-Lane Prime Arterial and Street" A" is
classified as Class III Collector roadway, Ingress and egress to the site will be from Street "A." The
City Engineering Division has projected that the Fire Station will generate 100 average daily trips (ADT)
(assuming 10 persons @ 10 trips per day), This level of traffic would have a less than significant impact
on the local road network. The proposed project is consistent with the City's Transportation Phasing Plan
and General Plan Traffic Element No impacts to traffic and circulation are anticipated,

a) Increases in existing noise levels? 0 0 IS] 0
b) Exposure of people to severe noise levels? 0 IS] 0 0
Comments: Heavy earth moving equipment may produce noise levels in excess of 70 dB(A) at a
distance of SO feet during the construction period of the proposed project Construction noise is
considered to be less than significant because (I) it is a short-term activity with intermittent periods of
noise generation, and (2) the area surrounding the extension of Street" A" and the fire station are
vacant. Grading operations would occur between 7:00 a.m, and 5:00 p,m, Monday through Friday,
Construction noise is exempt from the provisions of the City noise ordinance (see Municipal Code
section 19,68,060), Consequently, noise associated with the grading operation would be regulated by
conditions included in the approved grading permit
Noise associated with the operation of the proposed tire station would be comparable to other fire
stations in the city, Fire sirens would be the most noticeable source of noise associated with the
proposed tirc station; however, such sirens are exempt from noise regulations (Municipal Code Section
19,68,060,A), Air conditioning equipment will be at ground level and in an enclosure,
The emergency generator may produce a noise level or 85 dB at 80 feet without noise attenuation, The
generator would be operated during power outages and for monthly testing, Monthly testing is normally
conducted on Saturdays, Noise standards for the adjacent multi-family residential area are set forth in
Table III of Chapter 19,68 of the Municipal Code. The standards are as follows:
7 a,m, to 10 p,m, (weekdays)/8 a,m, to 10 p,m, (weekends) - 55 dB(A)
10 p,m, to 7 a,m, (weekdays)/IO p.m. to 8 a,m, (weekends) - 45 dB(A)
The Village Two multi-family residential units planned for construction to the south and west of the
proposed fire station could be significantly impacted by the emergency generator noise even though a
six-foot high wall is also proposed to be constructed along the proposed fire station's southern and
western site boundary,
Mitigation: Mitigation measures listed in Section XIX would reduce noise impacts to a less than

Comments: New utilities to be installed in Street" A" and La Media Road as part of the Village Two
Otay Ranch project would serve the proposed fire station. Onsite drainage facilities will he constructed
as approved on the project's improvement and grading plan,
The proposed fire station is within the Otay Water District 7]] Zone service area, The projected daily
water demand is 3.348 gallons based on an average project demand of2,232 gallons per day (gpd) per
acre, Water service would be available from a 20-inch transmission main in La Media Road south of
Olympic Parkway or a 12-inch line in Street" A," Either of these lines would meet the water service
requirements of the proposed fire station. including fire flow requirements, The estimated hydraulic
grade line in the 71] Zone system during a maximum day demand plus I ,500 gallons per minute (gpm)
at the proposed tIre station site is 665 feeL The residual pressure is 84 pounds per square-inch (psi); the
minimum allowable pressure is 20 psL
Sewage flows from the proposed fire station will flow by gravity to the Poggi Canyon Interceptor in
Olympic Parkway through the 12-inch gravity line in La Media Road or an 8-inch gravity line in Street
"A." The Sewer Service Study for Village Two and Fire Station #7 indicates that either of these lines
have sufficient capacity to serve the proposed fire station, Sewage generation from the proposed fire
station has been calculated at 3,750 gallons per day (gpd) based on an average generation rate of 2,500
gpd/acre, The City Engineering Department also reported that either sewer line would adequately serve
the proposed fire station because it is rated at 13-4 Equivalent Dwelling Units (EDUs) and the Village
Two sewer system has 4,276 EDU's of remaining capacity, Consequently no significant impacts would
occur.
563 ChecklisLdoc 12 Prepared 6/7/02

The projected surface runoff from the proposed fire station site is 5 cubic feet per second (cfs), The
runoff would be conveyed to the Poggi Canyon Creek channel via the storm drain system installed for
Village Two. The Poggi Canyon regional detention facility has been designed to reduce the 100-year
storm event flows to below the pre-developed 1 DO-year peak !low condition, Pre-development and post-
development calculations are contained in the Master Drainage Study for Poggi Canyon Creek and Wolf
Canyon Creek - Otay Ranch Village Two TM Study dated March 20,2002, Consequently, development

The following project revisions or mitigation measures have been incorporated into the project and
will be implemented during the design, construction, and operation of the project:
GEOPHYSICAL
Erosion and Sedimentation
L Prior to the issuance of a grading permit, a site-specific water quality report shall be submitted to
the City Engineering Department that addresses all applicable regulations established by the U,S,
Environmental Protection Agency (USEPA) as set forth in the Natural Pollutant Discharge
Elimination System (NPDES) permit requirements for urban runoff and storm water discharge
and any regulations adopted by the City of Chula Vista pursuant to the NPDES regulations or
requirements. The site-specific water quality report will address pollutants of concern and
implementation of Best Management Practices (BMPs), This study will to ensure that pollutants
and runoff Irom the project will be reduced to the maximum extent practicable (MEP).
Implementation of the recommended 13MPs during and afler construction would reduce erosion
and scdimentation in the downstream storm drain system to a less than signitìeant level. The
reconunendations provided in the approved water quality report shall also be adopted as
requirements of the proposed project:
2, The National Pollutant Discharge Elimination Systems (NPDES) Permit Order No, 2001-01 and
Best Managemcnt Practices (BMPs) are required to be implemented during and afler construction
to prevent sedimentation and other pollutants trom entering the storm drain system, Short-term
construction erosion would be reduced to a less than significant level by the installation of
temporary desilting and erosion control devices, These devices include desiiting basins, berms,
hay bales, silt fences, dikes, and shoring, Pollutants resulting from the use of the site as a fire
station shall be reduced to a less than significant level through the installation of a flow-based
catch basin and/or gross pollutant traps that capture and retain floatable, trash, debris, and fine
sand,
