Recent changes to flood insurance and building requirements as follows:
- February 2000, FEMA rescinded mandatory flood insurance covering 18 square mile area
adjacent to lower LA River (see attached map). Approximately 130,000 residents in
west Long Beach, Los Angeles, Carson, and Gardena are no longer required to carry
flood insurance, saving the property owners approximately $10 million in annual premiums.
- September 2000, FEMA downgraded the Zone AR designation to Zone A99, lifting the
special restrictions for new buildings.
- May 2001, FEMA rescinded mandatory flood insurance covering a 10 square mile area adjacent
to the Rio Hondo Channel. Approximately 70,000 residents in Pico Rivera, Downey, and Montebello
are no longer required to carry flood insurance.
- January 2002, the remaining A99 flood zones were removed across 64 square miles,
encompassing 12 communities, and relieving some 300,000 property owners of mandatory flood
In 1991, the cities of Bellflower, Carson, Downey, Lakewood, Paramount, Pico Rivera, and South Gate
formed the LACDA Alliance to promote support for the Federal funding of the LACDA Project and efforts
to minimize the impacts of mandatory flood insurance in the pre-project overflow area. The LACDA
Alliance has been an important agency partner to ensure the timely completion of the LACDA Project.
Need for State Involvement
State Subvention Funding needed to allow County to complete urgently needed projects that were deferred
to allow LACDA Project to proceed on schedule. The LACDA Project will afford critical flood protection
to some 36 miles of State-owned highway and freeway facilities as well as other major facilities
associated with the State's economy.
