Florence Avenue, just west of the Interstate 605 freeway. The site is currently improved with a
high voltage transmission tower.
10. Description of surrounding properties:
A variety of land uses surround the subject site. A summary of these uses is as follows:
North - The properties to the north of the project site are developed with high voltage
transmission towers; no other structures exist. As such, the properties are not zoned
and do not have a General Plan land use designation. In addition, Interstate 5 and
Interstate 605 intersect just north of the project site.
East - The area to the east of the project site is developed with a Caltrans maintenance facility
and Interstate 605 and as such, does not have a zoning or General Plan land use
designation.
South - The property to the south of the project site is developed with a public park. The
property's zoning is C -2 (General Commercial) and its General Plan land use
designation is OS (Open Space).
West - The area to the west of the project site exists as the San Gabriel River. As such, the
area does not have a zoning or General Plan land use designation.
11. City Characteristics:
The City of Downey is 12.8 square mile community that is located in the southeastern part of Los
Angeles County. According to the 2000 census, the population of the City of Downey is 107,323
persons. The City of Downey is located about 12 miles southeast of downtown Los Angeles and
is bounded by: the Rio Hondo River on the west; Telegraph Road on the north; the San Gabriel
River on the east; and Gardendale Street and Foster Road on the south. Cities bordering

The analysis considers the project's short -term impacts (construction - related), and its operational or day -
to -day impacts. For each question, there are four possible responses. They include:
1. No Impact. Future development arising from the project's implementation will not have any
measurable environmental impact on the environment and no additional analysis is required.
2. Less Than Significant Impact. The development associated with project implementation will
have the potential to impact the environment; these impacts, however, will be less than the levels
or thresholds that are considered significant and no additional analysis is required.
3. Potentially Significant Impact Unless Mitigated. The development will have the potential to
generate impacts which will have a significant effect on the environment; however, mitigation
measures will be effective in reducing the impacts to levels that are less than significant.
4. Potentially Significant Impact. Future implementation will have impacts that are considered
significant, and additional analysis is required to identify mitigation measures that could reduce
these impacts to less than significant levels.

(a and b): The City of Downey is located within the southeastern portion of Los Angeles County. This area is
relatively flat and does not contain any scenic vistas, rock outcroppings or state scenic highways. Furthermore,
the proposed project will not result in the removal of any existing trees nor are there any historical buildings within
the area.
(c): An inherent concern with construction of cellular towers is the potential for a visual impact to the surrounding
area. To address this concern, the applicant has designed the cellular antennas as an integrated part of the
existing high voltage transmission tower. This design will allow the proposed antennas to blend in with the project
site's existing structure and thereby have a less than significant aesthetic impact on the surrounding vicinity.
(d): The proposed antennas and ground- mounted equipment will not require the use of lights and as such will
not create impacts from light or glare.
2. AGRICULTURE RESOURCES. In determining whether impacts to agricultural resources are significant
environmental effects, lead agencies may refer to the California Agricultural Land Evaluation and Site
Assessment Model (1997) prepared by the California Department of Conservation as an optional model to
use in assessing impacts on agriculture and farmland. Would the project:
0
(a through c): The City of Downey is an urbanized area that is mostly built out with only infill development
potential. There are no agricultural lands within the City's boundaries. Furthermore, the City's General Plan
(Vision 2025) does not include provisions for agricultural uses in the future. While the City has a variety of zoning
districts, in which agricultural uses are only allowed in the Open Space (O -S) zone. The project site is not an O-
S zoned property.

3. AIR QUALITY. Where available, the significance criteria established by the applicable air quality
management or air pollution control district may be relied upon to make the following determinations. Would
the project:
a. Conflict with or obstruct implementation of the applicable air ❑ ❑ 12 ❑
quality plan?
b. Violate any air quality standard or contribute substantially to ❑ ❑ 12 ❑
an existing or projected air quality violation?
c. Result in a cumulatively considerable net increase of any
criteria pollutant for which the project region is non- ❑ ❑ 0 ❑
attainment under an applicable federal or state ambient air
quality standard (including releasing emissions which
exceed quantitative thresholds for ozone precursors)?
❑ ❑ 0 ❑
(a through e): Long term air quality impacts are not anticipated with the operation of the proposed cellular
antennas or equipment. The project will not emit particulates into the air and will be powered through the existing
electrical grid. Furthermore, cellular towers are self sustained and do not require frequent employee visits to the
site, other than monthly maintenance.
Short term impacts, however, are anticipated during project construction and are created as the project is
constructed. Nevertheless, the impacts are short term in nature; and therefore, are considered to be less than
significant. Furthermore, any construction related impacts are addressed by the mitigation measures set forth in
the Mitigation Monitoring Program of the Final Environmental Impact Report (FEIR) that was prepared for the
Downey Vision 2025 Comprehensive General Plan Update (SCH #2004031159), which was certified on January
25, 2005.

impede the use of native wildlife nursery sites?
e. Conflict with any local policies or ordinances protecting ❑ ❑ ❑
biological resources? (i.e. tree preservation ordinance).
f. Conflict with the provisions of an adopted Habitat
Conservation Plan, Natural Community Conservation Plan, ❑ ❑ ❑
or other approved local, regional or state habitat
conservation plan?
Response:
(a through f): The City of Downey is an urbanized area that is mostly built out with only infill development
potential. According to the Final Environmental Impact Report (FEIR) that was prepared for the Downey Vision
2025 Comprehensive General Plan Update (SCH #2004031159), which was certified on January 25, 2005, there
are no known species identified as a candidate, sensitive, or special status species; no known wetlands; and no
known native resident or migratory fish or wildlife species or established native resident or migratory wildlife
corridors, or native wildlife nursery sites within the City. Furthermore, the City of Downey does not have any local
policies or ordinances protecting biological resources, nor is there any adopted Habitat Conservation, Natural
Community Conservation, or other approved local, regional or state habitat conservation plans. Finally, the
proposed project will not result in any of the existing mature landscaping, other than minimal amounts of grass,
being removed from the site.
5. CULTURAL RESOURCES. Would the project:
a. Cause a substantial adverse change in the significance of a ❑ ❑ ❑
historical resource as defined in CEQA Guidelines 5064.85?
b. Cause a substantial adverse change in the significance of
an archaeological resource pursuant to CEQA Guidelines ❑ ❑ ❑
5064.5?
c. Directly or indirectly destroy a unique paleontological ❑ ❑ ❑
resource or site or unique geologic feature?
d. Disturb any human remains, including those interred outside ❑ ❑ ❑
of formal cemeteries?
Response:
(a): While the existing structures on site are older than 50 years, they are not known to be associated with
events of persons of historically significant importance. Additionally, the existing structures do not have a unique
architectural appearance or are likely to yield information about history or prehistory. Finally, the proposed
project will not involve the demolition or alteration of any structures on or off the site, as such; there is no
potential impact to historical structures.
(b and c): Archaeological and /or paleontological resources are not typically encountered within the City of
Downey and there are no known archaeological or paleontological resources on the site. Nevertheless, should
any be discovered during construction, the applicant is required to comply with the provisions set forth Section
15064.5 of Title 14, Chapter 3 of the California Code of Regulations (CEQA Guidelines).

(d): Since burials within the City of Downey have occurred in the Downey Cemetery since the late 1880's,
human remains are not typically encountered during construction. Nevertheless, should any be discovered
during construction, the applicant is required to comply with the provisions set forth Section 15064.5 of Title 14,
Chapter 3 of the California Code of Regulations (CEQA Guidelines).
6. GEOLOGY AND SOILS. Would the project:
a. Expose people or structures to potential substantial adverse
effects, including the risk of loss, injury, or death involving:
1) Rupture of a known earthquake fault, as delineated on
the most recent Alquist - Priolo Earthquake Fault Zoning ❑ ❑ 12 ❑
Map issued by the State Geologist for the area or based
on other substantial evidence of a known fault?
2) Strong seismic ground shaking?
3) Seismic - related ground failure, including liquefaction?
4) Landslides?
b. Result in substantial soil erosion or the loss of topsoil?
d. Be located on expansive soil, as defined in the California
Building Code, creating substantial risks to life or property?
e. Have soils incapable of adequately supporting the use of
septic tanks or alternative wastewater disposal systems
where sewers are not available for the disposal of water?

(al and a2): The City of Downey is not located within a Alquist - Priolo Earthquake Fault Zone. Nevertheless, the
City, like much of Southern California, is located in an area that is considered seismically active. The nearest
known fault to the City is the Whittier fault, which is approximately 5 miles from the City's boundaries. According
to the Southern California Earthquake Data Center, the maximum probable earthquake that can be generated by
the Whittier Fault is a magnitude 7.2. This impact is considered to be less than significant since all construction
is required to be designed and built to the seismic safety standards set forth in the Building Code, which will
minimize the risk of loss, injury, or death due to seismic activity.
(a3): According to the Final Environmental Impact Report (FEIR) that was prepared for the Downey Vision 2025
Comprehensive General Plan Update (SCH #2004031159), which was certified on January 25, 2005, the entire
City is within a Liquefaction Zone. According to the Building, all new construction is required to submit a soil and
geological report prior to the issuance of building permits. Said report shall include an analysis of the liquefaction
potential and recommend a foundation design to address the local condition.
CEQA INITIAL STUDY - PLN -11 -00088 3.0 - ENVIRONMENTAL EVALUATION
(b): Loss of topsoil and /or soil erosion is not expected since the is landscaped. Furthermore, construction
activities are required to incorporate best Management Practices (BMP's) to prevent soil erosion during
construction.
(c and d): Prior to the issuance of building permits, the applicant is required to submit a soil and geological
report. Said report shall demonstrate how the project will mitigate any soil stability issued, including lateral
spreading, subsidence, liquefaction, and expansive soils.
(e): The City of Downey is an urban area that is served by a sanitary sewer system. New septic tanks are
prohibited within the City.
7. HAZARDS AND HAZARDOUS MATERIALS: Would the project:
a. Create a significant hazard to the public or the environment
through the routine transport, use, or disposal of hazardous
materials?
b. Create a significant hazard to the public or the environment
through reasonably foreseeable upset and accident ❑ ❑ ❑
conditions involving the release of hazardous materials into
the environment?
c. Emit hazardous emissions or handle hazardous or acutely
hazardous materials, substances, or waste within one -
quarter mile of an existing or proposed school?

8. HYDROLOGY AND WATER QUALITY. Would the project:
a. Violate any water quality standards or waste discharge
requirements?
b. Substantially deplete groundwater supplies or interfere
substantially with groundwater recharge such that there
would be a net deficit in aquifer volume or a lowering of the
local groundwater table level (e.g., the production rate of
pre- existing nearby wells would drop to a level which would
not support existing land uses or planned uses for which
permits have been granted)?
d. Substantially alter the existing drainage pattern of the site or

(a through f): The proposed project, as with all construction within the City of Downey, is required to comply
with the National Pollution Discharge Elimination System (NPDES). This includes retaining storm water from the
impervious areas created by the project and allowing it to recharge into the ground. By retaining the water on
site, there will be no violations to water quality standards, no additional impact to the storm water system, and no
alterations to existing drainage patterns from the site and surrounding area.
(g and h): Pursuant to Flood Zone Map No. 0606450005A, as revised on January 11, 2002, the subject site is in
Zone X, which is a 500 -year flood zone. Accordingly, impacts from a 100 -year flood event are not anticipated.
(i): The subject site, as with most of the City, is located between the San Gabriel River and the Rio Hondo
Channel. According to the Final Environmental Impact Report (FEIR) that was prepared for the Downey Vision
2025 Comprehensive General Plan Update (SCH #2004031159), which was certified on January 25, 2005, both
of these flood control channels have been designed to meet or exceed the discharge capacity for a 100 -year
flood. Furthermore, the FEIR notes that there are no concerns with a potential levee break on either channel.

(a through d): The proposed cellular antennae and ground mounted equipment does not generate any
significant noise, and as such, will not result in a long term impact. Notwithstanding this, short term impacts are
anticipated during construction of the project. These impacts are considered less than significant due to the short
term nature of construction. Additionally, the construction is required to comply with Municipal Code Section
4606.5, which limits the hours of construction.
(e and f): The City of Downey is not located within an airport land use plan, within two miles of a public airport or
public use airport, or within the vicinity of a private airstrip.

(a through c): The proposed cellular antennae and related equipment will not result in the creation of jobs or
housing; therefore will not induce growth to the area. Furthermore, the antennae will be located on an existing
high voltage transmission tower with all related equipment being located on the ground under the tower and as
such will not displace people or create the need for new residences.

15. TRANSPORTATION /TRAFFIC. Would the project:
a. Cause an increase in traffic which is substantial in relation to
the existing traffic load and capacity of the street system
(i.e., result in a substantial increase in either the number of
vehicle trips, the volume to capacity ratio on roads, or
congestion at intersections)?
❑ ❑ ❑
b. Exceed, either individually or cumulatively, a level of service ❑ ❑ ❑
standard established by the county congestion management
agency for designated roads or highways?
c. Result in a change in air traffic patterns, including either an ❑ ❑ ❑
increase in traffic levels or a change in location that results
in substantial safety risks?
d. Substantially increase hazards due to a design feature (e.g., ❑ ❑ ❑
sharp curves or dangerous intersections) or incompatible
uses (e.g., farm equipment)?
e. Result in inadequate emergency access? ❑ ❑ ❑
f. Result in inadequate parking capacity? ❑ ❑ ❑
g. Conflict with adopted policies, plans, or programs supporting ❑ ❑ ❑
alternative transportation (e.g., bus turnouts, bicycle racks)?
Response:
(a and b): The proposed project will not directly or indirectly result in new development. Furthermore, the site is
unmanned and typically only requires a site visit once a month for maintenance. As such, it will create a
significant number of vehicle trips or create traffic impacts
(c): The unmanned cellular antennae will not alter existing air traffic patterns or create additional air traffic.

(d through g): The proposed cellular antennae will be located on an existing high voltage transmission tower
with all related equipment being located on the ground under the tower. This location is ideal since it will not
create a hazard to pedestrians, emergency access, bicycles, alternative transportation, or impede on the existing
parking.

(a): The City of Downey is an urbanized area that is mostly built out with only infill development potential.
According to the Final Environmental Impact Report (FEIR) that was prepared for the Downey Vision 2025
Comprehensive General Plan Update (SCH #2004031159), which was certified on January 25, 2005, there are
no known species identified as a candidate, sensitive, or special status species. Additionally, there are no known
wetlands, as defined by Section 404 of the Clean Water Act, within the City. Furthermore, the proposed project
will not result in the demolition of any existing structures. As such, the proposed project will not degrade the
quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife
population to drop below self- sustaining levels, threaten to eliminate a plant or animal community, reduce the
number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major
periods of California history or prehistory.
(b and c): Based on the analysis contained within this initial study, the proposed project is not anticipated to
create a significant impact. When considered with past, current, and other proposed projects in the City, it is
unlikely that the project will contribute towards any cumulative impact. Therefore, the project will not cause
substantial adverse effects on human beings, either directly or indirectly
