Sno-Stilly Riparian Zone Management Strategy
From Salish Sea Wiki
Salmon Recovery and TMDL implementation. A narrative effort will summarize existing ecosystem recovery strategies. A spatial analysis will evaluate a broadly defined riparian zone, differentiate between floodplain and tributary units, and then target interventions at a parcel level. This work will develop priorities for the National Estuary Programs riparian easement program, and aims to integrate farmland protection work to increase Snohomish Agricultural Resilience.
- Snohomish CD has secured NEP funding for a planning phase.
- The County and NOAA have pledged technical assistance support.
- The project team has had two meetings to define scales of analysis, data sources, and roles.
- We have completed a draft spatial analysis, that is currently under technical review
- We are aiming for a public discussion of riparian zone strategy refinement at a November riparian workgroup.
- File:SCD 2016 riparian easement grant proposal.pdf describes funding requested from NEP riparian easement program for planning.
- File:SCD 2016 riparian easement grant figures.pdf provides maps and concept for expanded riparian zone analysis.
- Pilot areas were selected based on recent prioritization work in the Lower Stillaguamish Floodplain, North Fork Stillaguamish Floodplain, Jim Creek Watershed, and Pilchuck Creek Watershed, recent habitat analysis in Pilchuck River Watershed, and impending TMDL analyses in the Pilchuck River Watershed and French Creek Watershed.
