ENVIRONMENTAL REVIEW --NOTICE OF DETERMINATION
BY
CITY OF NEWPORT BEACH
PUBLIC WORKS DEPARTMENT
SAN JOAQUIN HILLS ROAD SUBDRAIN AND SURFACE DRAIN RECONSTRUCTION
A preliminary environmental review of the project for San Joaquin
Hills Road Subdrain and Surface Drain Reconstruction has been performed. The
review was conducted in accordance with the requirements of the California
Environmental Qualiity Act of 1970, the State "Guidelines for Implementation of
the California Environmental Quality Act of 1970," and the City's "Policies and
Procedures for Implementing the California Environmental Quality Act."
The environmental statement has been reviewed and was approved by the
City's Environmental Affairs Committee.
As a result of the preliminary review, it has been determined that:
1. The project is approved.
2. The project will not .have a significant effect on the environment.
3. An environmental impact report has not been prepared. A Negative
Declaration has been prepared and is attached hereto.

PUBI.IC WORKS DEPARTMENT
SAN JOAQUIN HILLS ROAD SUBDRAIN AND SURFACE DRAIN RECONSTRUCTION
1. PROJECT LOCATION: The proposed subdrain and surface drain
reconstruction is along the existing southerly San Joaquin Hills Rpad
right-of-way, beginning at 350 feet easterly and ending at 1100 feet
easterly, approximately, of Back Bay Drive in the City of Newport
Beach, County of Orange.
2. PROJECT DESCRIPTION: An approximate 10 foot width by 750 foot length
of area will be cleared of brush and an existing asphalt concrete
surface drain. A 12 inch diameter subdrain pipe will be installed in a
5 foot deep trench, the pipe will be covered with 3 feet of drainage
gravel, and a 5 foot wide concrete "veep ditch will be built above the
grave for the 750 foot length. Approximately 400 linear feet of
concrete curb and gutter will be built to replace the remaining
portion of asphalt curb.
3. PROJECT GOALS: The project will reduce the quantity of shallow
groundwater under San Joaquin Hills Road, thereby reducing the need to
reconstruct the roadway in the not too distant future. The project
also provides for restoration of surface drainage capability and for
the control of rainfall runoff along San Joaquin Hills Road.
4. EFFECT ON THE ENVIRONMENT: There will be no significant long-term
irreversible or irretrievable effects on the environment. There will
be minimal, acceptable short-term disturbances caused by construction
activity.
5. BASIS FOR NEGATIVE DECLARATION: This project is consistent with the
General Plan of the City of Newport Beach and will not have a
significant effect on the environment.
6. INITIAL STUDY: The Public Works Department of the City of Newport
Beach as prepared the Negative Declaration and its Initial Study in
accordance with Articles 6 and 5, respectively, of Chapter 3,
Guidelines for Implementation of the California Environmental Quality
Act. Copies of the Initial Study may be obtained from the Public Works
Department during normal business hours.

A. CONFORMANCE WITH THE GENERAL PLAN: This project is consistent with
existing zoning, plans and other land use controls established in the
General Plan of the City of Newport Beach.
B. ENVIRONMENTAL CHECKLIST FORM:
An Environmental Checklist Form (copy
portion of this Study. The following
questions presented on the checklist,
answers:
attached) has been completed as a
statements, referenced to
explain all "yes" and "maybe"
II,1.b.& c. An approximate 10 foot wide by 750 foot long area behind
the southerly curb of San Joaquin Hills Road, beginning
approximately 350 feet easterly of Back Bay Drive, will be
cleared of brush and asphalt concrete surface drain. The
earth will be trenched 2 feet wide by 5 feet deep and a
subdrain pipe will be installed and covered with gravel
to 2 feet below the existing top of curb elevation. A
5 foot wide concrete "vee" surface drain will then be
built to replace the. existing surface drain, which is
severely broken and overgrown with vegetation.
II.3.f.& g. The purpose of the subdrain construction is to intercept
the substantial quantity of ground water migrating
northerly from the undeveloped parcel southerly of San
Joaquin Hills Road. This shallow ground water will be
conveyed into an existing storm drain system, which
empties nearby into Upper Newport Bay. The quantity of
ground water will decrease within the top 5 feet of earth
adjacent to San Joaquin Hills Road.
II.14.e. The effect of the subdrain construction will be to relieve
the excess moisture in the subgrade of San Joaquin Hills
Road. If this excess is not removed, the roadway will
rapidly deteriorate, lose its structural integrity, and
require reconstruction (including subdrain) instead of
routine surface maintenance.

a. Does the project have the potential to
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?
I. 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 which occurs in a relatively brief
definitive period of time while long-
term impacts will endure well into the
future.)
c. Does the project have impacts which
are individually limited, but cumu-
latively 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?
