Level 2 Meeting - SPW
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

Objectives for 3 Stewardship Plans
Synthesize Existing and Historic Information
Clarify and Identify Watershed Management
Problems/Issues
Improve or Develop Stewardship
Opportunities
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?
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?
Overall Approach
for Synthesizing Existing Information
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

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.
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
Rough classification of the mainstem
Permanente Creek slopes
Approach will
be adapted to
local conditions.
based on Montgomery and Buffington (1997)
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)
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
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)?
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
Next Steps
Next Meeting: March 2004
