  • Corralitos

  • Foothill
  • Llagas
  • Maple
  • Paradise

Please view our Annual Flood Report (PDF) that also has a local map showing the location of the SFHA's.

Sand Bag Stations In Morgan Hill
Update as of November 2025 - the City has sand and empty bags available for residents, newly relocated to the Community Park parking lot. Remember to bring your own shovel. A nearby address to map to for the Community Park parking lot is 171 W. Edmundson, across from the tennis courts.

In addition to Community Park, Valley Water supplies a similar sand bag station on Old Monterey Road near Llagas Road. The closest nearby address to map to is the El Toro Fire Station, 18300 Old Monterey Road. 

Valley Water's Flooding & Safety webpage includes a map to check locations for other sand bag sites in the greater South County area. Click on the icon for each location for an address and details.

Please note that the City's previous sand bag location at Edes Court has been relocated to the Community Park parking lot. The Valley Water map link may still show last year's location address.

Sand bag supplies are removed when rainy weather subsides.
