Special Flood Hazard Areas (SFHA’s)

Know Your Local Flood Hazard:

Flooding in our City is caused by:

  • A creek over topping its banks;
  • Clogged catch basin or storm drains;
  • Poor site drainage; Mud and debris laden flows from the hills above Milpitas.

Certain areas have been designated by the Federal Emergency Management Agency (FEMA) as Special Flood Hazard Areas (SFHA). Approximately one-quarter of the City is within these flood zones SFHAs are by definition, areas within the 100-year flood boundary as mapped by FEMA. A “100-year flood” refers to a flood level with a 1 percent or greater chance of being equaled or exceeded in any given year. There is a 26% chance that a structure located in an SFHA will be inundated by a 100-year flood during the life of a 30-year mortgage. In comparison, the risk of fire is approximately 5% in the same time period. Smaller floods have a greater chance of occurring in any given year and can still create a significant hazard to life and property.

In Milpitas, SFHAs are generally located near the following major creeks: Calera, Penitencia, Berryessa, Los Coches, and Tularcitos.
