Lake Dalwigk Restoration Work
The Lake Dalwigk Community-Based Urban Greening Project will enhance a minimally-vegetated, 44-acre stormwater detention basin in central Vallejo. A diverse palette of carefully selected native plants will be installed, including 240 trees; 2,200 shrubs; 16,000 rush, sedge, and grass plugs; and 5 acres of wildflower and grass seed. In addition to improving the park aesthetics, this new vegetation will provide cover and food resources for wildlife and migratory birds, mitigate climate change by capturing atmospheric carbon, and improve water quality by filtering and storing stormwater. Trees will help shade the existing foot path around the perimeter of the lake, which connects nearby neighborhoods to a Park & Ride facility, thus improving access to public transportation and reducing greenhouse gas emissions.
Visitor outreach will include volunteer planting events beginning Winter 2018-2019, and continue through Winter 2020-2021. Bi-annual bird surveys will be conducted by Napa-Solano Audubon and volunteer citizen-scientists. Park amenities will also be installed, including interpretive stops, a hydration station, and dog waste stations with bags and garbage cans.
This project will be completed thanks to funding by the State Coastal Conservancy, and in cooperation with several project partners, including:
- Vallejo Flood and Wastewater District
- Greater Vallejo Recreation District
- Vallejo Watershed Alliance
- City of Vallejo
- Napa-Solano Audubon Society
- Natural Resources Conservation Service
- Vallejo City Unified School District
Several species of resident and migratory waterfowl can be spotted at Lake Dalwigk throughout the year and at our bi-annual volunteer bird surveys
