Hi Mike:


As indicated on the San Diego Seismic Safety Study maps, Coast Walk is located in Geologic Hazard Category 43, which is characterized as generally unstable coastal bluffs, with unfavorable jointing, and local high erosion rates.  A geotechnical investigation report should be required for any proposed development in this area, which demonstrates adequate slope stability, adequate bluff edge setbacks to account for bluff recession, and suitable site conditions for the intended use.


Best regards,
