Flood Zone Basics for Gilbert Residents
New Gilbert residents are often surprised to learn that certain areas within the Town are susceptible to flooding. Gilbert slopes from east to west - and in the event of heavy rainfall, flood waters can accumulate in areas adjacent to the east side of railroad and canal embankments. Residents should exercise caution around washes and low-lying areas, which can quickly fill with water during a severe storm.
In partnership with the Flood Control District of Maricopa County, the Town has taken many measures to reduce the risk of flooding in the community. For example, Freestone and Crossroads Parks serve a dual purpose as retention facilities to collect and hold flood waters. Also, the Eastern Maricopa Floodway helps to intercept flood water flows from the north before they even reach Gilbert, while also intercepting flows from the Sonoqui and Queen Creek Washes. The Town’s Floodplain Management Ordinance - originally adopted in January 1980 and most recently updated in October, 2013 - establishes minimum development requirements for areas identified as Special Flood Hazard Areas (SFHAs). These requirements minimize flooding and erosion hazards and protect the natural resources within flood prone areas.
Flood Insurance for Gilbert Residents
The Town of Gilbert participates in the National Flood Insurance Program (NFIP), meaning that all property owners in Gilbert can purchase flood insurance. For communities in the NFIP, Federal Emergency Management Agency (FEMA) has a voluntary program called the Community Rating System (CRS) in which participating communities receive discounts on flood insurance premiums based on community activities such as open space preservation, establishment of a storm water management program, drainage system maintenance, and flood warning and response. The Town of Gilbert has participated in the CRS program for many years.
Once every 5 years, the Insurance Services Office verifies Gilbert’s floodplain management program. In April 2019, FEMA informed the Town of an improvement in our CRS program rating, resulting in an additional 5% reduction in flood insurance rates for Town of Gilbert residents in the SFHA. The discount for Gilbert policy holders goes up from 10% to 15% for policies issued or renewed on or after May 1, 2019. There are currently a total of 204 flood insurance policies in Gilbert’s SFHA, each with an average annual premium of $829. This CRS improvement will result in a 5% reduction ($41 average annual savings) for each of these 204 flood insurance policies in the special flood hazard area.
