Natural Resources Agency Awards Grants to Address Flooding in Urbanized Areas and Provide Multiple Benefits Across the State

Published Date:

SACRAMENTO – To guard against urban flooding and deliver multiple environmental benefits, the California Natural Resources Agency today directed $87.6 million in grant funding to 26 projects across the state.

The projects, 19 of which will benefit disadvantaged communities, employ a mix of traditional and green infrastructure solutions to alleviate urban flooding and protect persons and property from flood damage. The grants are part of the Urban Flood Protection grant program funded by Proposition 68.

“Amidst drought, we cannot forget about California’s flood risks,” said California Secretary for Natural Resources Wade Crowfoot. “Climate change is driving more intense winter storms that can bring severe flooding. In response, these exemplary projects will help to protect local communities, infrastructure and natural places from worsening flood threats.”

In 2018, California voters passed the California Drought, Water, Parks, Climate, Coastal Protection, and Outdoor Access for All Act of 2018 (Proposition 68), which directed the Natural Resources Agency to administer a competitive grant program for projects that address flooding in urbanized areas and provide multiple benefits.

A few projects are highlighted below, with the full list of projects following.

The City of Mendota was awarded $4.2 million to reduce severe flooding along two blocks of Naples Street with low impact development street tree sponges and conventional drainage infrastructure to capture and convey stormwater runoff to an extended dry detention basin.

The City of Richmond was awarded $1.5 million to restore Rheem Creek to address creek overflows and flooding in the Rollingwood community. The project will grade a geographically stable channel, remove invasive species and excessive sediment, and plant native riparian vegetation to improve creek habitat.

The Trust for Public Land was awarded $3 million to acquire approximately 56 acres of floodplain and uplands along the lower Ventura River to protect it from development and provide future restoration to help mitigate flooding impacts downstream. Once restored, the property will be open to the public as a new open space park.
