Carson FAQ
Is my Carson property in a flood zone?
Most of Carson is in Zone X (minimal flood hazard), but properties near the Dominguez Channel or Compton Creek may be in Zone AE. Use the FEMA Map Service Center (msc.fema.gov) and enter your address to see the current FIRM panel for your parcel.
Do I need flood insurance in Carson?
Flood insurance is mandatory only for properties in a Special Flood Hazard Area (Zone A or AE) with a federally backed mortgage. In Zone X it is optional but recommended — about 25% of NFIP claims nationally come from properties outside the high-risk zones.
What if I want to build an addition in a Zone AE area?
Carson building permits in Zone AE must demonstrate that the lowest finished floor of habitable space is at or above the Base Flood Elevation shown on the FIRM, use flood-damage-resistant materials below BFE, and meet anchoring and venting requirements of CBC §1612 and ASCE 24. Improvements valued above 50% of the existing structure require the entire building to be brought into compliance.
