D2: Revitalize Stream, Upland and Wetland Habitat

Project D2 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 such as giant reed (Arundo donax), as well as education for nearby landowners and other stakeholder groups on the control of harmful species.

Project D2 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 habitat so it can 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 April 2017)

  • Staff are developing watershed master plans, Stream Corridor Priority Plans, and mapping habitats in order to manage activities, develop partnerships, and meet regulatory requirements (CEQA, environmental permits).

  • Completed 2.5 acres of non-native tree, shrub, and vine removals along the Guadalupe River for the Clean, Safe Creeks and Natural Flood Protection grant and to meet U. S. Army Corps of Engineers levee and flood protection criteria. Here are maps of pre-revitalization non-native and invasive plant cover prior to removal:

  • Controlled 7 to 8 acres of invasive plants along Stevens and Saratoga creeks in coordination with the district's Stream Maintenance Program (SMP)
  • Controlled approximately 4 acres of smooth cordgrass (Spartina alternflora) in partnership with the Invasive Spartina Project

     Meeting Key Performance Indicators:  

1. Revitalizing approximately 14 acres of non-native habitats on the Guadalupe River, Stevens Creek, Saratoga Creek, and South San Francisco Bay.

2. Developing partnerships with Santa Clara County Parks, California Coastal Conservancy, and Midpeninsula Regional Open Space District.

3. Plant palettes for revegetation projects

 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 (Completed see item 3 above).
