1 Jordan River Watershed Council STREAM FUNCTION INDEX (SFI) July 15, 2009

2 OUTLINE Stream Function Index (SFI) purpose, structure, and methodology SFI Data and Reports Recommendations and Opportunities What s s Next? Discussion

3 SFI Purpose Rapid assessment protocol of stream habitat, hydrology, water quality and social factors that influence both water quality and quality of life Streams are used to indicate overall watershed health Used as the monitoring tool for the Water Quality Stewardship Plan (WaQSP( WaQSP) Used to assess BMP effectiveness Updated on a six-year cycle with the WaQSP

4 SFI Structure

5 SFI Data and Reports Data was collected between 2006 and 2008 Final SFI report will be available (online or via SLCo Flood Control Division) Late August (Annual Watershed Symposium) City Reports will be distributed to cities and posted on Water Resources Website ( Late August (Annual Watershed Symposium CD s s of GIS data will also be available: Kathlyn J. Collins (801)

6 Targets? Many targets were based on stream type (Rosgen Stream Type) Other targets were based on fishery and water quality beneficial use categories

7 Stream Types in SLCo

8 Stream Types in SLCo

9 SFI Habitat Function Habitat Function was divided into two sub-groups: Stream Channel Pool/Riffle Ratio Minimum Water Depth Fish Passage Habitat Structure Flow Diversions Riparian Habitat Riparian Width Riparian Density

15 SFI Hydrology Function Hydrology Function was divided into two sub-groups: Floodplain Conveyance Floodplain Development Floodplain Connectivity Stream Stability Pfankuch Stability Hydraulic Alteration

16 SFI Hydrology Function

17 SFI Hydrology Function

18 SFI Hydrology Function

19 SFI Water Quality Function Water Quality Function was divided into three sub-groups: Regulatory 303(d) list status Aquatic Macroinvertebrates Monitoring Total Phosphorus Temperature Total Dissolved Solids (TDS) Dissolved Oxygen (DO) E. Coli

25 EHI Final Scores

26 SFI Social Aesthetic Function Social Aesthetic Function was divided into three sub-groups: Aesthetics Management Visual Aesthetic Trails (Lines) Connectivity Resource Compatibility Amentities (Nodes) Location Accessibility (ADA approved) Restrooms Resource Compatibility (Nodes)

27 SFI Social Aesthetic Function

28 SFI Social Aesthetic Function

29 SFI Social Aesthetic Function

30 SFI Social Aesthetic Function

31 SFI Social/Aesthetic

32 SFI Final Scores

33 Recommendations Many of the SFI/EHI scores could be improved through Stream Restoration and Enhancement Projects. Wind River Watershed Bank Stabilization $46,000 to $222,000 per river mile Channel Rehabilitation $41,000 to $137,000 per river mile Riparian Restoration $4,000 to $8,000 per river mile North Carolina Ecosystem Enhancement Program Rural Streams $ per foot Urban Streams $ per foot Salt Lake County Jordan River prices have varied based on labor and material cost plus the need (or lack thereof) to contract construction work out

34 WaQSP Cost Estimates

35 Walden Park Project

36 WaQSP Implementation Tasks Develop sensitive areas overlay zone ordinance template for use on the west side of unincorporated Salt Lake County and within cities. Expand water quality and quantity data collection. Provide assistance, coordination, facilitation and oversight for water quality improvement grant applications. Implement BMPs for stormwater quality purposes.
