Shoreline and Coastal Bluff Management Strategies Draft MEIR
Environmental Impact Analyses
armoring the entire coastal bluff and as discussed above. The City's Shoreline and Coastal
Bluff Protection Ordinance takes a more proactive approach in reducing erosion of the bluffs
and minimizes effects that could result in a future need to construct a more intrusive device.
The City's Shoreline and Coastal Bluff Protection Ordinance imposes setbacks and blufftop
erosion management measures such as irrigation controls, restrictions on grading of bluff tops,
and seacliff faces and restrictions on drainage over bluff tops and seacliff faces as follows:
Place shoreline defense structures at the most feasible landward location.
Use native vegetation that requires minimum watering.
Lawns and similar ground cover are permitted but are subject to strict watering
requirements.
Landscape standards shall discourage work on the bluff face.
Automatic irrigation systems shall be prohibited within 100 feet of the coastal bluff unless the
systems incorporate automatic shut-off valves and moisture sensors.
Retrofit with drip, mist and other very low flow irrigation devices of irrigation systems on the
bluff or within 25 feet of the bluff top edge.
Drainage over the bluff edge or through the bluff shall be prohibited unless the water is
contained within a pipe drainage system approved by the City Engineer.
In addition, the City's ordinance requires that wall designs address wave reflection. The
Ordinance requires that wall design should consider the surface characteristics of the seacliff
and of the protective structure (slope and surface roughness), and the locations of the seacliff
and seacliff protective structure relative to each other, to mitigate the negative effects of wave
reflection from protective devices. Sand loss impacts from wall reflection aspects not mitigated
through design can be mitigated through sand banking in coordination with the mitigation of
other consequences (see below).
Mitigation
Continuation of this policy, in the long-term, will likely result in armoring the entire natural
coastal bluff with shoreline protection structures in Solana Beach. To address such a prospect,
described below are additional "mitigation measures" that, if implemented by the City and/or
other governmental agencies, might reduce or avoid the long-term need for total coastal
armoring. It is important to understand, however, that under Alternative 1, the City would not be
taking any action, but instead would be leaving its existing Ordinance in place. As a result, the
City would not be "approving" any "project" with "significant environmental effects" for which
"mitigation measures" must be adopted if "feasible." In other words, in the unique situation
facing the City, standard CEQA terms "environmental impacts" and "mitigation" do not
