PLANNING COMMISSION
PLANNING DEPARTMENT
- CITY OF CARLSBAD - CARLSBAD BOULEVARD SHORE
ECTION - Request of a Planning Commission Determination for General
Plan Consistency for the construction of a shore protection seawall and the
placement of rock revetment designed to protect Carlsbad Boulevard and its
associated improvements from storm wave damage. The project area is on
the west side of Carlsbad Boulevard south of the inflow jetty on the north
side of Agua Hedionda Lagoon to the beach area around the warm water
outflow jetty on the south side of the Lagoon. The project site is located in
Local Facilities Management Zone 1 with General Plan and zoning
designations of Open Space.
I.RECOMMENDATION
That the Planning Commission ADOPT Resolution No. 3191 approving the Negative
Declaration issued by the Planning Director and ADOPT Resolution No. 3192 approving
PCD/GPC 91-1 making the determination that the proposed City project is consistent with
the General Plan based on the findings and subject to the conditions contained therein.
II.PROJECT DESCRIPTION AND BACKGROUND
Section 65401 of the California Government Code requires that a General Plan Consistency
Determination be made for major public works projects.
Project Background
This project is for the protection of the recently widened Carlsbad Boulevard and associated
improvements and utilities. The City Council declared its intent of reconstructing and
widening Carlsbad Boulevard through Council Resolution No. 7770 after the storm damage
of the 1983 winter season. The Carlsbad Boulevard widening was intended to be followed
by the implementation of an unspecified shore protection measure.
The Carlsbad Boulevard improvements requiring protection include a divided roadway with
a median, parallel parking on the west side, sidewalks on both sides, landscaping and
lighting. In addition, there are utilities including a 12 inch water main, a four inch H.P.
gas main, telephone lines, electrical lines and storm drains.

MARCH 6, 1991

A feasibility study was performed by Woodward-Clyde Consultants to assess various shore
protection measures. Ultimately, a 3 foot 6 inch high concrete wall was identified as the
most effective and cost-beneficial shore protection measure. The City Council authorized
the preparation of a project design in July 1990 (Resolution No. 90-242).
Project Area
Part of the project area, as shown on Attachment "A", is approximately 2,600 feet in length
on the west side of existing Carlsbad Boulevard between the inflow jetty on the north side
of Agua Hedionda Lagoon and the warm water outflow jetty on the south side of the
Lagoon. This stretch is Carlsbad Boulevard's lowest elevation averaging +13 to +16 feet
above Mean Sea Level Datum. The average beach width is 150 to 200 feet with one to six
inch diameter cobbles covered by a thin summer time sand layer averaging one to three
feet in thickness. This sand is usually removed by wave action during the winter wave
season. Periodic overtopping and washing out of Carlsbad Boulevard often occurs during
episodes of high tide and high wave condition. This stretch of Carlsbad Boulevard has a
history of being washed out resulting in closure and costly repairs. This area will be the
site of the main shore protection seawall.
The rest of the project area is located approximately 8,00j0 feet to the south and will
contain a smaller seawall (south seawall) and rock revetment to protect Carlsbad
Boulevard.
Main Seawall
The proposed main concrete seawall is approximately 2,200 feet long and will tie into the
existing rock revetments near the jetties at each end of the project area. The color of the
concrete seawall will be Mesa Buff (Beach Sand).
There will be five recessed breaks in the wall to allow for beach access approximately every
300 feet in the form of three vehicle access ramps and two pedestrian stairways. The three
ramps are intended for lifeguard and emergency vehicle access but will also be for
pedestrians. These three ramp areas will include amenities such as one foot raised viewing
platforms, lifeguard towers, drinking fountains, trash receptacles, benches and triple trunk
palm tree landscaping as shown on Attachments "C", "D" and "E". The walls in the
lifeguard ramp areas will be treated with one layer of clear tile. No tables or flagpoles are
proposed. The two pedestrian stairways will not have any art treatment or amenities.
The seawall will include or contain a relief pattern (described below) and will be staggered
so as to not present a continuous linear feature.
Seawall Art Design
The main and south seawall will include an art design by artist Raul Guerrero, cast in relief
onto the length of the concrete wall by a mold. The proposed design, as shown on
Attachment "B", features a rhythmic fish pattern integrated with wavelets. This design is
PCD/GPC 91-1 - CARLS1AD BOULEVARD SHORE PROTE'

intended to add visual interest to the wall which will also receive a graffiti proof treatment.
The proposed fish pattern design and ramp amenities have been reviewed and approved
by the City's Arts Commission.
South Seawall
The 240 foot long south seawall will be the same color and design as the main seawall.
See attachment "A" for the location.
Slope Stabilization
The third component of the project is the placement of rock revetment to protect the
southbound lanes of Carlsbad Boulevard. From erosion and potential wave undercutting
which could lead to slope failure see Attachment "A" for the location.
III. ANALYSIS
Planning Issues
1. Is the proposed Carlsbad Boulevard shoreline protection project consistent with the
goals and policies of various elements of the General Plan? Specifically, is the
project consistent with the following elements?
* Open Space
* Land Use
* Public Safety
* Arts
* Scenic Highways
DISCUSSION
Open Space Element
This project will enhance the outdoor recreational opportunities within this stretch of the
City beach/open space area while providing shoreline protection to Carlsbad Boulevard.
As such it complies with the following goals and policies of the Open Space Element:
Guideline #6 "open space lands held by the public for recreational use should be
accessible and should be provided with essential utilities, public
facilities and services"
Guideline #7 "proper design criteria should be utilized to preserve the unique and
special resources in the City and to integrate them into the design of
any development."

MARCH 6, 1991

Land Use Element
Lagoon Guideline (#3) calls for future development adjacent to lagoons and beaches to
"provide maximum physical and visual accessibility to these resources for public use and
enjoyment." The proposed development will accomplish this objective while also providing
public safety and protecting Carlsbad Boulevard from costly damage and is therefore
consistent with this element.
Public Safety Element
The proposed improvement will improve public safety, minimize the possibility of injury
or damage to property and improve emergency access (both to the beach, and via Carlsbad
Boulevard). The project therefore complies with Goals 1 and 3 of the Safety Element of
the General Plan.
Arts Element
Two objectives of this element are to "develop and maintain an environment that
encourages diverse program activity in the arts" and "to establish the City's role in
encouraging and providing works of art in public places". To meet these objectives, two
policies are stated.
1. An Arts Commission shall provide "a forum for arts concerns and recommendations
to elected officials and their staff concerning arts issues".
2. Contract "for cultural services with local art organizations and individual artists".
An individual artist has contracted to develop the seawall's art design.
The proposed wall design was reviewed and approved by the City's Arts Commission and
an individual artist was contracted to develop the wall's design. The installation of art
within this highly visible stretch of the City's beach area will satisfy this objective (No. 1
above).
Scenic Highways Element
Carlsbad Boulevard is eligible for a scenic highway designation by this element. By
providing amenities and protecting Carlsbad Boulevard from damage in this scenic area,
the project addresses one of the goals of this element to "provide a process for the
establishment of convenient and safe scenic pleasure drives and scenic routes to major
recreational areas and points of historical, scenic or cultural significance" (Goal #2). Since
this project adds to the preservation and enhancement of the scenic qualities of a selected
corridor (Carlsbad Boulevard), it is also consistent with Policy C.3.3 of the Circulation
Element which calls for coordination "with the development of the scenic route program
addressed in the Scenic Highways Element . . . ".

IV. ENVIRONMENTAL REVIEW
Staff has reviewed the Environmental Impact Assessment Part I (EIA) and has completed
the EIA Part II. The environmental benefits from this project include (1) the increased
protection of Carlsbad Boulevard and associated improvements from storm damage and/or
slope failure, (2) increased public safety, (3) enhanced opportunities for recreation by
pedestrians and handicapped persons, and (4) the creation of a barrier to overwash and
overtopping and wind blown sand. The primary potential environmental impact was visual
aesthetics. This impact has been reduced to insignificance by (1) the development and
implementation of the proposed art design and associated amenities and (2) the application
of graffiti-proof treatment to the seawalls. The Planning Director has determined that as
designed the project will not have a significant adverse effect on the environment and
therefore, has issued a Negative Declaration on January 31, 1991. This environmental
review has undergone the required state level review due to its coastal zone location.
There were no public comments received during the public review period for this Negative
Declaration.
