Dear Ms. Mattson:
This is in response to your request for comments on Public Notice Number CESPL-2009-00575 -
MLM for the San Elijo Lagoon Restoration Project (Gent) in Encinitas, San Diego County,
California.
Please review the current effective countywide Flood Insurance Rate Maps (FIRMS) for the
County of San Diego (Community Number 060284) and City of Encinitas (Community Number
060726), Maps revised September 29, 2006 . Please note that the City of Encinitas, San Diego
County, California is a participant in the National Flood Insurance Program (NFIP) . The
minimum, basic NFIP floodplain management building requirements are described in Vol . 44
Code of Federal Regulations (44 CFR), Sections 59 through 65 .
A summary of these NFIP floodplain management building requirements are as follows :
• All buildings constructed within a riverine floodplain, (i. e. , Flood Zones A, AO, AH, AE,
and Al through A30 as delineated on the FIRM), must be elevated so that the lowest
floor is at or above the Base Flood Elevation level in accordance with the effective Flood
Insurance Rate Map .
• If the area of construction is located within a Regulatory Floodway as delineated on the
FIRM, any development must not increase base flood elevation levels . The term
development means any man-made change to improved or unimproved real estate,
including but not limited to buildings, other structures, mining, dredging, filling,
grading, paving, excavation or drilling operations, and storage of equipment or
materials. A hydrologic and hydraulic analysis must be performed prior to the start of
development, and must demonstrate that the development would not cause any rise in
base flood levels . No rise is permitted within regulatory floodways.
