The Santa Clara Basin


Santa clara basin watershed management initiative

Santa Clara Basin Watershed Management Initiative

  • Started in 1996

  • Stakeholders include:

    • USEPA & Regional Water Quality Control Board

    • State and Federal Resource Agencies

    • Cities, Towns & County

    • Santa Clara Valley Water District

    • Valley Transportation Authority

    • Environmental Advocates

    • Citizens Groups

    • Business Interests


Watershed planning process

Watershed Planning Process

  • Watershed Characteristics Report

  • Pilot Watershed Assessments

  • A Vision for Our Watershed

  • Subgroups created 112 Action Worksheets

  • Action Plan Technical Advisory Group

    • Which of these actions are being done now?


Watershed action plan

Watershed Action Plan

  • For each of seven issues:

    • An aspect of the watershed vision

    • Natural & social history of environmental issue

    • Existing law & regulation

    • Status of implementation

    • Watershed management objectives


A plan to get savvy about urban watersheds

  • 1. Stream Protection & Restoration

  • Vision: Support salmon & steelhead

  • - Restore seasonal flows and overbanking

  • - Restore and maintain in-stream habitat

  • History: Dams, flow diversions, channelization

  • Science: River continuum & stream equilibrium

  • Policy: Flows, Permits, Sediment TMDLs

  • Status: Stewardship added to District mission

  • Objective: Integrate flood protection & restoration

  • - Commit to long-term Adaptive Management

2. Floodplain & Riparian Planning

Vision: Continuous riparian corridors & floodplains

- For flood management, habitat, parks, trails

History & Science: Ideas about flood control and floodplain management (Gilbert White, 1942)

- Landscape ecology & riparian corridors

Policies: NFIP, City & District, Trails Plan

Objective: Integrated planning process

  • Shared sense of place

3. Conserving Biodiversity

Vision: Comprehensive plan to preserve biodiversity

(variety of habitats, organisms, & genetic makeup)

Also provide for jobs & housing

History: Open space preservation along with sprawl

Science: What is critical habitat?

Policy: ESA, HCPs, NCCPs

Status: HCP/NCCP in Santa Clara County

Objective: Creation & management of habitat reserves

3. Conserving Biodiversity in Wetlands

Status: Acquisition of 15,000 additional acres

- Expand the SF Bay National Wildlife Refuge

Objective: Facilitate restoration of salt ponds, maintain flood protection, protect water quality

- Comprehensive planning process

4. General Plans & Specific Area Plans

Vision: Protected corridors with intense development

History: Modernism + incentives + economics = Sprawl

Policies: California General Plan Law, “Smart Growth”

Objective: Incorporate vision into General Plans

- Reach out to “smart growth” advocates

- Plan for designation & acquisition of habitat corridors

5. Site Development & Drainage

Vision: Retrofitted drainage systems protect streams

Science: Imperviousness & effects on streams

- Site and drainage design solutions

History: Cities’ slow changes in design standards

Policy: Amended municipal stormwater permit

Objective: Assist implementation of permit & coordinate with other aspects of vision

6. Assessments, TMDLs, & Discharge Permits

Vision: Waters fishable, swimmable, without pollution

History: Success in cleaning up wastewater discharges

- New issues: Flow diversions, exotic species, nonpoint

Science: Sources, fate, transport, effects of each pollutant

Policies: Stormwater discharge permit, TMDLs

Status: Site-specific objectives for Cu & Ni

- TMDLs for Hg, PCBs, CHCs, diazinon, dioxins/furans

- Watch list for trash, pathogens, sediment/siltation, PBDEs, EDCs

Objective: Improve TMDL process, consensus-based discharge permits

7. Water Conservation & Recycling

Vision: Rely primarily on local sources, maximize conservation & recycling, balance with other needs

History: Overpumping, subsidence, dams & diversions, water imports, salt marsh conversion

Policy: California conservation policy

- Central Valley Improvement Act

- Flow cap on wastewater discharge

Status: 10% of wastewater flow is recycled

Objective: Use state-mandated Integrated Water Resource Planning to gauge & focus water conservation & recycling


A watershed plan is all about

A Watershed Plan is All About…

  • A shared vision of the future

  • Collective discovery and learning

    • About watershed science

    • About environmental policy & regulation

  • Aligning, coordinating & integrating existing environmental protection policies & programs

  • Creating an effective long-term institutionfor adaptive management of watersheds


Watershed initiative s future role

Watershed Initiative’s Future Role

  • Facilitate stakeholder groups

    • Genuine collaboration

    • Fresh technical & policy perspectives

  • Recommend solutions to policy-makers

    • Bring consensus to boards, managers, & funders

  • Educate and involve the public
