|Floodplains in Chandler
Several small areas in Chandler are located in what is commonly referred to as the 100-year floodplain. These areas are generally adjacent to canal banks and railroad track embankments where water ponds can develop during periods of heavy rainfall.
To determine whether your property is located in a floodplain, go to the Flood Control District of Maricopa County website at fcd.maricopa.gov/business/maps.aspx. This site provides the current effective floodplain map and additional resources including available Elevation Certificates and Flood Hazard Identification Studies. Currently there is an active study in which west Chandler is included, the Tempe Area Drainage Master Study (ADMS) to assess flooding in this region.
The City of Chandler participates in the National Flood Insurance Program (NFIP) through the Department of Homeland Security's Federal Emergency Management Agency (FEMA). As a participant of the NFIP, the City adopted Floodplain Management Resolution 4876 and has established development requirements consistent with federal criteria.
Flood insurance is available to almost everyone from the federal government’s NFIP. Most homeowners’ policies do not cover flood losses. Contact your insurance agent concerning such coverage. More information regarding flood protection is available from FEMA (fema.gov or floodsmart.gov).
Construction within flood zones is tightly regulated by the Maricopa County Flood Control District. Permits are required for any building or site alterations to ensure maximum protection against flooding is maintained.
