ENVIRONMENTAL IMPACT ANALYSIS INITIAL STUDY

subdivision of acres into 4--L�
The proposed development is located on the
II. ENVIRONMENTAL CHECKLIST
The environmental checklist completed for this project
shows the potential environmental impact of this project
III. MITIGATION MEASURES
The environmental checklist identified areas where an
environmental impact will take place as a consequence of
the proposed development. The following pages discuss
these impacts and mitigation measures to be taken to
reduce these effects.
1. Earth
a. No impact
b. & c. The proposal will result in disruptions,
displacements, compaction, overcovering of
the soil and a change in the topography and
ground surface features. This is due to
proposed grading to be done when the
implementation of the project is commenced.
Unless mitigation measures are taken, once
the land surface is disturbed wind erosion
might occur. Note should be made that no
exceptional topographical features exist on
the site.
Mitigation measures proposed are as follows:
- Prior to any grading permits being issued,
the Applicant shall submit (to the Planning
and Development Department) an interim
landscape program for the entire tract which

shall be for the purpose of wind erosion and
dust control.
The Applicant shall submit a grading plan
prior to issuance of building permit with a
engineering geological and soils engineering
report.
Drainage disposal facilities shall be
provided on the site as required by the
Director of Public Works. og��
d. to f. No impact.
g. This area is located in Groundshaking Zone IV
as identified on the Riverside Seismic 1
Geology information maps. The site, however
is not in close proximity to any established
fault line, nor does it lie in any zone
susceptible to liquefication. There will
however be some groundshaking in the event of
fault activity, depending upon the magnitude,
location and other characteristics of the
tremor.
The Uniform Building Code provides seismic
safety standards for buildings which help
mitigate the above impact.

Fringe Toed Lizard Habitat Conservation Plan
has identified special reserves to be set
aside for these reptiles. The developer of
this site will pay a mitigation fee to help
acquire these special reserves.
d. & e. No impact.
Noise
a. & b. This development will result in an
increase in existing noise levels but this
will occur primarily during construction
periods. The City Ordinance has set forward
work hours for construction crews and adverse
noise after hours should therefore be minimal.
Future residents in this development will be
exposed to traffic noise from
Mitigation measures for the above are as
follows:
- The La Quinta General Plan requires noise
studies for all projects within 2,800 feet of
the centerline of major streets, i.e.,
- The General Plan also states that barrier
design standards should also be developed to
minimize the visual impact of sound barriers.
- The General Plan also states that the
following setbacks are required,
along 20 feet and along
10 feet.
Light and Glare
This proposal will introduce an additional
illuminated area to the City. To alleviate any
possible problems the City reviews all lighting
plans prior to installation.
Land Use. �V6AE��
Natural Resources 6Xo ,�
a. This development will increase the rate of
use of natural resources. The effect will
however be gradual and proportionately very
small.

11. Population
This proposal introduces single family units to the
La Quinta area. The affect of residential growth
in this area is addressed by the Master
Environmental Assessment of the La Quinta General
Plan.

13. Transportation/Circulation

increase of vehicular movement in the
surrounding area. This issue has been dealt
with in the Master Environmental Study for
the La Quinta General Plan.

this will be gradual and minimal.
14. Public Services
a. to f. This development will result in the
increased demand for public services. The
Master Environmental Study for the La Quinta
General Plan has addressed these issues.
The developer is required to pay fees or make a
land dedication for park and school facilities and
form a landscape maintenance district.

21. Mandatory Findings of Significance.
a. Does the project have the potential
to degrade the quality of the

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. Does the project have the potential to
achieve short-term, to the disadvantage
of long-term, environmental goals? (A
short-term impact on the environment is
one in which occurs in a relatively brief
definitive period of time while long-term
impacts will endure well in the future).
c. Does the project have impacts which are _
individually limited, but cumulatively
considerable? (A project may impact on two
or more separate resources where the impact
on each resource is relatively small, but
where the effect of the total of those
impacts on the environment is significant).
d. Does the project have environmental _
effects which will cause substantial
adverse effects on human beings, either
directly or indirectly?

IV. Determination
(To be completed by the Lead Agency).
On the basis of this initial evaluation:
I find that the proposed project COULD NOT have a
significant effect on the environment, and a NEGATIVE
DECLARATION will be prepared.
I find that although the proposed project could have
a significant effect on the environment, there will
not be a significant effect in this case because the
mitigation measures described on an attached sheet
have been added to the project.
A NEGATIVE DECLARATION WILL BE PREPARED.
I find the proposed project MAY have a significant
effect on the environment, and an ENVIRONMENTAL
IMPACT REPORT is required.
