  1. Santa Clara Valley Water DistrictWatershed Stewardship Plans for Lower Peninsula, West Valley, and Guadalupe February 23, 2004Level 2 Meeting - SPW

  2. Meeting Objectives • Debrief on project status for new attendees • Review the project schedule • Reach consensus on project terminology • Receive input on stakeholder engagement strategies • Receive input on management issues/questions • Receive input on coarse-scale assessment methodology

  3. Lower Peninsula Watershed Area West Valley Watershed Area Guadalupe Watershed Area

  4. Objectives for 3 Stewardship Plans • Synthesize Existing and Historic Information • Clarify and Identify Watershed Management Problems/Issues • Improve or Develop Stewardship Opportunities

  5. Discussion topics:Stakeholder Engagement Strategy • Management Questions/Issues • Existing Conditions (e.g. where are the hardened channels?) • Issues to be Addressed through the Planning Process (e.g., clarify sensitive areas along the creeks) • Collective Vision for Each Watershed • District Staff Document - Board Linkage? • WRPC Linkage? • Natural Food Protection? • Other key stakeholders?

  6. Review Stakeholder online Comments on TM#3 • Level 2 needs to include all WMI / SPW participants including regulatory agencies. • Invitations / mailing list needs updating and action. • How will meeting outcomes and other stewardship elements be measured? • Process for submitting “Action Items” for consideration to District Management?

  7. Coarse Scale Main characteristics of each Watershed organized by functional indicator Provide foundation for understanding stewardship issues, problems, or opportunities Provide basis for selection of more detailed analysis objectives or areas (e.g., watersheds or creeks - 3) Finer Scale Field Work (new data) for the areas identified Information for conceptual design solutions Overall Approach for Synthesizing Existing Information

  8. Stewardship Plans Coarse And Fine Scale Indicators

  9. Review Stakeholder Online Comments for TM #4A (4.2 and 4.3) • GIS Coordination and data access? • Information and reports identified have been distributed to the project team. • Use of interviews with District Staff to help identify projects needed and wanted by the District will help ensure follow through. • Fine-scale methods will be explained in greater detail in TM#4b. • Rosgen will be used where possible.

  10. Coarse Scale Analysis • Data Compilation • WMI Characterization Report • WMI Assessment Reports • FAHCE Summary Report • SCVURPPP Sediment Impairment Report • GIS Layers – land ownership, zoning, existing and historical land use, imperviousness, mining • Analysis • Longitudinal Profiles 3rd Order+ streams (e.g., main stem, tributaries) • Geomorphic Process Domains; Potential Erosion • Landslide Susceptibility • Identify Data Gaps And Strategize How to Deal with These data gaps

  11. Rough classification of the mainstem Permanente Creek slopes Approach will be adapted to local conditions. based on Montgomery and Buffington (1997)

  12. Permanente Creek erosion hazard • Preliminary - methodology being refined. • Current map does not include geology, land use, or mass wasting • Results provide foundation for general stewardship planning (e.g., ordinances)

  13. Guadalupe Overview • Example Template - not first draft • Additional historical ecology and background on water supply and flood protection objectives to define feasible restoration trajectories. • Additional value added maps and summary tables (e.g., erosion hazard) • Need to implement coarse-scale analysis

  14. Stakeholder Online Comments on Guadalupe Summary • No comments on template format suggests miscommunication to stakeholders on purpose of document. • Several factual corrections and additions to be considered in developing draft. • Geographical boundaries to be addressed in watershed plan (e.g., Alviso Slough)?

  15. Proposed Finer Scale Analysis • Based on a refined version of model used in Coyote Creek (combined HGM/IBI) • Fill in the Data Gaps for watershed or creeks selected or identified • Model provides more detailed functional analysis than previously available • Model uses existing and newly collected field data • Develop conceptual design solutions

  16. Next Steps • Next Meeting: March 2004 • Website:www.valleywater.org/_wmiClick on Stewardship Plan User Id: spw password:stewardship03
