North Shoreview Flood Improvement Project

November 2024 Project Update: 

On November 18, 2024, FEMA formally notified the City of San Mateo that changes shown on Letter of Map Revision (LOMR) Determination Document (dated May 29, 2024) were effective as of October 11, 2024.

The updated Flood Insurance Rate Map (FIRM) show changes in significant portions of the North Central and North Shoreview neighborhoods from Zone AE to Zone X.

What does this mean for you?

  • If your home is now mapped within Zone X (area with reduced flood risk due to levee), flood insurance becomes optional. 
    1. Please note: Flood insurance requirements are not dictated by the City and a homeowner’s ability to cancel existing policies will need to be addressed directly with mortgage lenders. The City urges residents to make individual decisions regarding flood risk and is not advocating for continuance or cancellation of flood insurance policies. 

Where can I find more resources?

Lastly, the City of San Mateo would like to remind residents of upcoming special assessments fees. In March 2018, voters of the North Shoreview and North Central neighborhoods approved the formation of a Special Assessment District to contribute funding toward the flood improvements protecting your community. The City deferred collecting fees until a formal resolution from FEMA was finalized. Now with the FIRM update, members of the North Shoreview Flood Assessment District can expect to see a fee on their 2025-26 property tax bills (note: not 2024-25), ranging from $62/year – $178/year for most single-family homes, with the typical amount being $108/year. The special assessment is set to expire 20 years after which the fee will no longer be collected. We understand this may be news to newer homeowners in the area and encourage residents to reach out should they have any questions regarding the assessment district.
