D2: Revitalize Stream, Upland and Wetland Habitat

This project allows the District to remove non-native, invasive plants, and revegetate habitat with native species when needed. Funding also restores degraded habitat between revegetated sites to create a more contiguous habitat corridor for wildlife. This project includes targeted control of especially damaging non-native, invasive plant species Arundo donax, and education for nearby landowners and other stakeholder groups on the control of harmful species. This project also helps implement the Stream Corridor Priority Plans developed in Project D3.


  • Increases viability of native riparian species by reducing competition from non-native, invasive species
  • Improves habitat by installing tidal and riparian plant species
  • Improves ecological function of existing riparian and wetland habitats to support more diverse wildlife species
  • Improves patchy wildlife corridors by increasing connectivity of habitat
  • Increases community awareness about the damaging impact that non-native, invasive plants have on local ecosystems

Project Status

(As of November 2017)

KPI #1: Revitalize at least 21 acres, guided by the 5 Stream Corridor Priority Plans

Removed approximately 12.5 acres of invasive exotic species to support existing native riparian habitat on the Guadalupe River, Stevens Creek, Saratoga Creek and South San Francisco Bay. 
  • Completed 0.5 acres of non-native tree, shrub, and vine removals along the Guadalupe River in addition to 2.0 acres completed under a Clean, Safe Creeks and Natural Flood Protection grant.  Here are maps of pre-revitalization non-native and invasive plant cover prior to removal:

  • Controlled invasive plants along 5.5 acres of Stevens Creek and 2.3 acres of Saratoga Creek in coordination with the District's Stream Maintenance Program (SMP)  

KPI #2: Provide funding for revitalization of  at least 7 of 21 acres through community partnerships

  • Established a partnership with the Midpeninsula Regional Open Space District
  • Negotiating partnerships with the California State Coastal Conservancy, City of San José, and Santa Clara County Parks. 
  • Working cooperatively with the City of San José on mid-Coyote Creek in response to the 2017 flood by mapping and assessing habitats to meet regulatory requirements for D2 native habitat revitalization (CEQA, environmental permits), following the District's SMP invasive vegetation removal. 
  • Formed the Santa Clara County Wildlife Corridors Working Groups with US Fish and Wildlife Services (USFWS), California Department of Fish and Wildlife (CDFW), CalTrans, Santa Clara Valley Transportation Authority (VTA), Santa Clara County Parks, Santa Clara Valley Habitat Agency, Peninsula Open Space Trust (POST), Open Space Authority (OSA), The Nature Conservancy (TNC), De Anza College, and others
KPI #3: Develop at least 2 plant palettes for use on revegetation projects

Completed 5 plant palettes for revegetation projects, landscaping and native gardens with links to use by birds, bees, butterflies, and wildlife. 

 Key Performance Indicators

  1. Revitalize at least 21 acres, guided by the 5 Stream Corridor Priority Plans, through native plant revegetation and removal of invasive exotic species. 
  2. Provide funding for revitalization of at least 7 of 21 acres through community partnerships.
  3. Develop at least 2 plant palettes for use on revegetation projects to support birds and other wildlife.
