ENVIRONMENTAL REVIEW --NOTICE OF DETERMINATION
A preliminary environmental review -of the proposed project for the
Balboa Island Bridge Rehabilitation, Phases I and II, has been per-
formed. The review was conducted in accordancewiththe requirements
of the California Environmental• Quality Act of 1970, the State "Guide-
lines 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.

BALBOA ISLAND BRIDGE REHABILITATION., PHASES I & II
(C-2014)
NEGATIVE DECLARATION
BY
CITY OF NEWPORT BEACH
PUBLIC WORKS DEPARTMENT
1. PROJECT LOCATION: The bridge is a portion of Marine Avenue, crossing
over Balboa Island Channel from the mainland to Balboa Island.
2. PROJECT DESCRIPTION: The bridge rehabilitation work includes pile
placement; restoration of existing piling and substructure; construc-
tion of pile caps, curbs, sidewalks, railing bases, approach slabs,
roadway surface, and connecting stairways and ramps; installation
of deck restraints (seismic ties), handrailing, roadway and naviga-
tion clearance lighting and expansion joints; striping and signing
for pedestrians, bicyclists and motorists.
3. PROJECT GOALS: The project provides for restoration of vertical load
capacity; deck restraint in the event of earthquake; restoration of
deteriorated concrete; increased safety for pedestrian and bicyclists;
conformance with navigational lighting standards; and a positive
aesthetic effect upon the bridge structure.
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 effects on the environment during
construction.
5. BASIS FOR NEGATIVE DECLARATION: This project is consistent with the
General Plan policies of Newport Beach and could not have signifi-
cant effect on the environment.
6. Initial Study: The Public Works Department of the City of Newport
Beach has prepared an initial study in accordance with Sections 15081
and 15082 of Chapter 3, Guidelines for Implementation of the California
Environmental Quality Act of 1970, Title 14, Division 6 of the
California Administrative Code. Copies of the study may be obtained
from said Department during normal working hours.

(C-2014)
INITIAL STUDY
BY
CITY OF NEWPORT BEACH
PUBLIC WORKS DEPARTMENT
A. CONFORMANCE WITH GENERAL PLAN POLICY
This project is in accord with the General Plan Policies of the City of
Newport Beach, in particular the topics "Circulation and Transportation",
"Future Growth", Preservation and Redevelopment", "Community Design" and
"Shorelines."
B. LAND USE
These improvements will be constructed within established rights -of -way,
and will not require the relocation of people or disturbance of build-
ings.
C. DISRUPTIONS OF THE SOIL
Additional piles must be driven along each pile cap to restore the
original vertical load capacity and to conform to current vertical load
design standards. These 16-inch square piles will be driven to approxi-
mate elevation.20 feet, or at least 6 feet into bedrock. Such driving
will cause local displacements of soil which are not considered signifi-
cant.
D. LIGHT AND GLARE
Incandescent deck lighting will be replaced as a portion of the project.
Proposed luminaires will be energy efficient high-pressure sodium which
provide good color rendition at low (70 watt) intensity. Light and glare
emitted from these fixtures should not create a significant deleterious
effect upon the environment.
E. ALTERATION TO WATERBORNE TRAFFIC
Pile and pile cap construction will reduce navigational channel clear-
ances. The proposed clearances and net reductions between piles are
21'-2" and 3'-8", respectively, through the center navigational span,
and 22'-6" and 2'-10", respectively, through the outside navigational
spans. It is felt that these clearance reductions will not inflict
substantial alteration upon waterborne traffic since 1) the majority of
boats anchored in Balboa Island Channel do not pass under Marine Avenue
en route to the harbor or ocean, and 2) the 11% reduction of clearance
through outside navigational spans will still provide adequate clearance
for the majority of waterborne traffic wishing to pass under Marine
Avenue.
Balboa Island Bridge Rehabilitation, Phases I & II Initial Study (cont'd)
F. SHORT-TERM EFFECTS
On -site construction is expected to begin in September 1980 and to be
completed by April 1981. Pile driving, which occurs during the first
stage of construction, will be quite noisy. The contractor will there-
fore be permitted to construct the project only during normal working
hours to ensure a minimum of disturbance.
Two flagmen will be required to direct one lane of traffic over the
bridge during those stages of construction when the other lane is un-
usable. It is felt that only a minimum of inconvenience will exist
since this construction will occur during the low -traffic season.
G. ENVIRONMENTAL CHECKLIST
An environmental checklist has been completed as a portion of this
study. See Appendix I (attached).

21. Mandatory Findings of'Significance.
(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?
b. Does the project have the poten-
tial to achieve short-term, to the
disadvantage of long-term, environ-
mental 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 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 environ-
mental effects which will cause
substantial adverse effects on
human beings, either directly
or indirectly?
