West Covina participates in the National Flood Insurance Program and enforces floodplain management regulations consistent with FEMA requirements. Local waterways include the San Gabriel River and five tributaries: Walnut Creek, San Jose Creek, Puente Creek, and Big Dalton Wash. Most of the City lies outside the 100-year floodplain, but some areas near these waterways carry Zone A or Zone AE designations on FEMA Flood Insurance Rate Maps (FIRMs). Development in Special Flood Hazard Areas requires elevation certificates, flood-proofing, and permits from the Community Development Department. The Safe Clean Water Program (Measure W) imposes a parcel tax of 2.5 cents per square foot of impermeable area within the LA County Flood Control District to fund stormwater quality improvements. Projects requiring soil disturbance permits must implement Best Management Practices per the NPDES Municipal Stormwater Permit. Flood maps are available through FEMA's Map Service Center at msc.fema.gov.
Building in a flood zone without proper permits and elevation certificates violates the NFIP. Non-compliance may result in inability to obtain flood insurance, building code violations, and potential loss of community NFIP eligibility.
