 City of Solana Beach
Section 2
Shoreline and Coastal Bluff Management Strategies Draft MEIR
Project Description
Encroachments into the public beach shall be mitigated to the satisfaction of the city
council.
B.
A special use permit for any other erosion control measure, bluff repair or work on the
coastal bluff not otherwise addressed in subsection A of this section, or in SBMC
17.62.100 shall be denied unless the city council finds that the measure is:
1.
A necessary preventative measure to stop or control erosion of the bluff; and
2.
The measure will not adversely affect the bluff.
In addition, Chapters 17.62.140 and 17.62.160 of the Solana Beach Municipal Code discuss the
maintenance and repair of defense structures and measures and restrictions for landscaping,
irrigation, and drainage on the bluff tops, respectively.
As the preceding discussion demonstrates, the City's Shoreline and Coastal Bluff Protection
Ordinance embodies a comprehensive strategy for limiting the circumstances in which shoreline
protective devices may be constructed, and for ensuring the minimization of the environmental
impacts such structures may create. The Ordinance creates what the City considers to be a
proactive approach intended to minimize the circumstances in which large intrusive seawalls are
necessary. Such a goal can be accomplished by allowing upon the receipt of permit
applications construction of small, nonintrusive structures (e.g., notch fills) as a means of
halting erosion before it becomes so pronounced that larger structures are necessary to protect
property owners' rights under the Coastal Act. (See Pub. Resources Code, 30235.)
Notably, an approval from the City by no means alters or eliminates a property owner's need to
obtain various additional permit approvals from other public agencies. Such entities include the
California Coastal Commission, and may include the California State Lands Commission and
the United States Army Corps of Engineers.
2.1.2 Intensity
Under the City's existing Ordinance special use permits for shoreline protection devices along
the Solana Beach coastline would continue. These devices include: various types of seawalls,
revetments, shotcrete walls/cave or notch infills, and cobble berms. Approximately 20 percent
of the Solana Beach coastline is armored with seawalls. The percentage of the Solana Beach
coastline with some type of protection increases to about 45 percent, when including concrete
installed on the coast to infill notches and seacaves, rip rap revetment (not in areas of other
types of protective devices) as well as rock bolts installed to stabilize the lower bluff.
Cantilever Seawalls
Cantilever seawalls are typically constructed to protect the bluffs from wave-energy erosion
caused by sand and cobble thrown against the toes of the cliffs. Seawalls stop soil erosion from
reaching the beach and can cause the potential loss of beach width in areas where the bluff
