FEMA updated the nation’s flood maps under a program called Map Modernization. The City of Santa Clarita’s flood maps prior to this were over thirty years old. As part of this effort, FEMA also required the reassessment of all structures shown on the previous maps as levees. The railroad embankment that runs along Railroad Avenue was previously credited as a levee. With new FEMA policies, the railroad embankment no longer meets current levee certification requirements and was decertified by FEMA. As a result, the flood map for the Newhall area is changing. 

Possible changes to the Flood Insurance Rate Map affecting your property:

  • Map change from high-risk zone (A zone) to a moderate risk flood zone (Shaded X zone)
  • Map change from high-risk zone (A zone) to a low-risk zone (Unshaded X zone)
  • Map change from low-risk zone (Unshaded X zone) to a higher risk zone (A zone)

If you have a mortgage from a federally regulated or insured lender and the building(s) on your parcel(s) are within the A zone, then by federal law, your lender must require you to carry flood insurance when these flood maps become effective.  Flood insurance is available through the FEMA’s National Flood Insurance Program (NFIP).  Contact your insurance agent to learn about the lower-cost Preferred Risk Policy Two-Year Eligibility Extension and “grandfathering” options offered by the NFIP for properties being mapped into higher-risk areas for the first time.

Local officials will be holding a public meeting on Tuesday, August 21, 2012 at 6:00 p.m. at Hart Hall located at 24151 Newhall Avenue.  City staff also will be available to assist residents one-on-one and provide information.

A Letter of Map Revision (LOMR) was issued to our community effective June 15, 2012 which fixed an incorrect zone designation released on the 2008 flood map for Newhall. This correction was necessary to ensure proper grandfathering when the new flood map becomes effective. This document should be presented to your flood insurance agent to make certain that you receive the correct grandfathering rates when purchasing flood insurance.
