Homes <br />built within 100-yearflood zones are required to purchase flood insurance. While regional and local stormwater drainage channels have largely mitigated <br />flood risks in Santa Ana, severe weather may still have a substantial impact on the areas protected by channels or in a 500-yearflood zone. <br />FEMA Flood Zones <br />_ Zone A, AE, AH, & AD 1 % Annual Chance Flood Hazard (100-Year Flood) <br />— Zone X, 0.2%Annual Chance Flood Hazard (500-Year Flood) <br />CITY OF SANTA ANA GENERAL PLAN <br />Sou¢e!
