 City of Solana Beach
Section 2
Shoreline and Coastal Bluff Management Strategies Draft MEIR
Project Description
mitigation fee" by the Coastal Commission). This alternative, in the long term, will likely result in
armoring the entire natural coastal bluff with shoreline protection structures in Solana Beach,
even if there is no policy at the City level to prevent construction of shoreline structures.
Notably, however, the past practices of the Coastal Commission, particularly in the nearby City
of Encinitas, strongly suggest that the Coastal Commission is less likely to implement a
proactive approach favoring notch fills and seacave fills than would occur under the No Project
Alternative, but instead is likely to take action only when erosive conditions have become so
severe that large, intrusive seawalls are the only viable means of adequately protecting bluff-top
properties. See Figures 2-1 through 2-7 for the location of areas potentially subject to bluff
protection structures.
2.2.2 Intensity
Under the repeal of the City's Ordinance, coastal development permits for shoreline protection
devices along the Solana Beach coastline would continue to be required; however the City of
Solana would relinquish its current responsibility under the Ordinance and would leave the sole
responsibility and approval for all shoreline protection devices to the California Coastal
Commission. These devices include: various types of seawalls, revetments, shotcrete
walls/cave or notch infills, and cobble berms. Because the California Coastal Commission,
under specified circumstances, cannot deny shoreline protection permits for the protection of
public and private properties, the armoring of the entire natural coastal bluff, especially with
seawalls, has a higher probability of occurring than would occur if the City's Ordinance were left
in effect.
2.2.3 Location
As mentioned previously, approximately 45 percent of the Solana Beach's coastline has various
types of shoreline and bluff protection devices in place. It would be too speculative to describe
site-specific locations for the construction of future shoreline protection devices and which
specific device would be constructed due to the unpredictability of wave and tide conditions,
beach width, and cliff strength (Flick 2001). Site observations indicate that there are currently
three unfilled seacaves along Solana Beach's shoreline that could be filled (Figures 2-1, 2-2,
and 2-4).
2.2.4 Implementation
Implementation costs and funding options for the various types of shoreline and bluff protection
devices under this alternative would be identical to those listed in Table 2-1.
2.3 Sand Replenishment and Retention Program Alternative
2.3.1 Characteristics
This alternative involves implementing a sand replenishment and retention program in Solana
Beach. This alternative is in addition to, though it should be complementary to, the San Diego
