This project allows Valley Water to revitalize habitat for rare, threatened or endangered species or vegetation types, and create a more contiguous corridor for wildlife, including pollinators. Funding helps to restore degraded habitat by removing invasive plants and/or revegetating with native species. Funding is prioritized for projects that include community partnerships or provide education for nearby landowners and other stakeholder groups on the control of harmful species.
The project will also create an Early Detection and Rapid Response Program to identify and treat small infestations of new weeds before they become established.
Increasing the quality and quantity of native habitat areas and improving the connections between them are important adaptive strategies to support native species as climate conditions change. It increases access to new areas for migration and more room for hiding, hunting, breeding and rearing as needs evolve and increase.
KPI #1: Acres revitalized
Continuing 3 partnerships to revitalize native habitats, cooperate on Early Detection and Rapid Response (EDRR), identify occurrences, and remove invasive plants:
- Midpeninsula Regional Open Space District (since July 2017): Midpen is working to bring back native landscapes and biodiversity that once thrived on the Bear Creek Redwoods Open Space Preserve above Lexington Reservoir. Volunteers removed harmful invasive plants along its creeks to improve habitat for rare wildlife. Click here for a map showing work areas.
- California State Coastal Conservancy (since 2018): Controlling invasive smooth cordgrass (Spartina alterniflora) in partnership with the CA State Coastal Conservancy and Invasive Spartina Project. Click for a map of invasive Spartina coverage
- City of San José (since 2018): Working cooperatively with the City of San José on Coyote Creek in response to the 2017 flood, Valley Water's Stream Maintenance Program removed some of the giant reed (Arundo donax) at Oakland Road. The City and its contractors continue giant reed clearing and native habitat restoration at this location. Map
KPI #2: Early Detection and Rapid Response Program Manual
- Draft target list of EDRR species has been developed
KPI #3: Identify and treat emergent invasive species
- 163 populations of target species have been identified and documented (10 new since 7/1/2021)
KPI #4: Information sheets for early detection of invasive species

FY22-36 Key Performance Indicators for the Safe, Clean Water Program
Revitalize at least 21 acres over a 15-year period through native plant revegetation and/or removal of invasive exotic species.
Develop an Early Detection and Rapid Response Program Manual.
Identify and treat at least 100 occurrences of emergent invasive species over a 15-year period, as identified through the Early Detection and Rapid Response Program.
Develop at least eight (8) information sheets for Early Detection of Invasive Plant Species.
Increases viability of native plant species by reducing competition from non-native, invasive species
Improves habitat by installing tidal, riparian, and upland plant species or allowing native vegetation to passively regenerate after treatment/removal of invasive species
Improves ecological function of existing riparian, wetland and potentially upland habitats to support more diverse wildlife species
Improves patchy wildlife corridors by increasing connectivity with nearby habitat areas
Increases community awareness about the damaging impact that non-native, invasive plants have on local ecosystems
Helps to prevent new invasive species from becoming established
Early Detection Invasive Species Information Sheets will guide staff and public on identification and treatment options, raise public awareness, and help prevent the spread of new noxious weeds

About the Safe, Clean Water and Natural Flood Protection Program
In November 2020, voters in Santa Clara County overwhelmingly approved Measure S, a renewal of Valley Water’s Safe, Clean Water and Natural Flood Protection Program.
The program was first passed by voters in 2000 as the Clean, Safe Creeks and Natural Flood Protection Plan, then again in 2012 as the Safe, Clean Water and Natural Flood Protection Program. The renewal of the Safe, Clean Water Program will continue to provide approximately $47 million annually for local projects that deliver safe, clean water, natural flood protection, and environmental stewardship to all the communities we serve in Santa Clara County.
While evaluating ways to improve the 2012 program, Valley Water gathered feedback from more than 21,000 community members. That helped Valley Water create the six priorities for the renewed Safe, Clean Water Program, which are:
Priority A: Ensure a Safe, Reliable Water Supply
Priority B: Reduce Toxins, Hazards and Contaminants in our Waterways
Priority C: Protect our Water Supply and Dams from Earthquakes and Other Natural Disasters
Priority D: Restore Wildlife Habitat and Provide Open Space
Priority E: Provide Flood Protection to Homes, Businesses, Schools, Streets and Highways
Priority F: Support Public Health and Public Safety for Our Community
Each year, Valley Water prepares a report providing a progress update for each of these program priorities, along with fiscal year accomplishments.
To ensure transparency and accountability to the voters, the ballot measure also created an Independent Monitoring Committee, appointed by the Santa Clara Valley Water District Board of Directors. The Independent Monitoring Committee annually reviews the program’s progress to ensure the outcomes are achieved in a cost-efficient manner and reports its findings to the Board. Additionally, the IMC also reviews each proposed 5-year implementation plan prior to its submittal for Board approval.
In addition, the program requires three independent audits.
