Summary
Placer County participates in the National Flood Insurance Program (NFIP) and enforces a Flood Damage Prevention Ordinance through Placer County Public Works. Any construction or development in a FEMA Special Flood Hazard Area (SFHA) requires a floodplain development permit and an Elevation Certificate.
Floodplain management is a community effort of corrective and preventive measures for reducing flood damage to properties. The program aims to protect public health and safety, reduce damage to buildings and contents, and prevent increases in flood damage from new construction. For building in flood areas, Placer County applies the Flood Damage Prevention Ordinance, Article 15.52. Residents in communities implementing floodplain management activities qualify for flood insurance premium rate reductions. Flood zone, elevation certificate, and construction requirement information is administered by the Department of Public Works.
Full Breakdown
Placer County's Flood Damage Prevention Ordinance is adopted under 44 CFR Part 60 and administered by Placer County Public Works. SFHAs in Placer County are identified on the FEMA Flood Insurance Rate Maps (FIRMs), typically Zone A, AE, AO, and AH along the American River, Bear River, Dry Creek, Auburn Ravine, Coon Creek, Pleasant Grove Creek, and other tributaries. Before construction or development begins inside an SFHA, the property owner must obtain a Floodplain Development Permit. New residential structures and substantial improvements must be elevated with the lowest floor at or above the base flood elevation (BFE); non-residential structures must be elevated or dry-floodproofed. An Elevation Certificate prepared by a licensed surveyor or engineer is required to document compliance and rate the structure for NFIP insurance. Mandatory federal flood insurance applies to federally backed mortgages on properties in SFHAs. Floodplain disclosure to buyers is required under Cal. Civ. Code §1103.
Violations & Fines
Development in an SFHA without a Floodplain Development Permit is a violation of the County's Flood Damage Prevention Ordinance enforced by Placer County Public Works and Building Services. Non-compliance can result in stop-work orders, fines, FEMA flood-insurance rating penalties, and required mitigation or removal.
