5.8.4 Painter Creek Stream Restoration

ProjectPainter Creek Stream Restoration Phase I
DescriptionRestoration of 1,400 feet of Painter Creek to stabilize streambanks, manage riparian vegetation, and improve in-stream habitat
NeedThe Upper Watershed Stream Assessment identified several areas of erosion on Painter Creek, many of which were concentrated in Reach 1 from Jennings Bay to Painter Creek Drive. The subreach between CR 110 and West Branch Road is identified in the HHPLS as a reach with low scour potential but expected future increased volume contributed by development to the west. The streambanks of this subreach are heavily wooded and steeply sloped. There are several spot erosion areas, and the heavy canopy limits the growth of understory and bank stabilizing vegetation. A stream restoration project on this 1,400 foot segment is proposed to thin riparian trees, revegetate the streambanks, add in-stream fish and macroinvertebrate habitat, and improve streambank stability through bioengineering. Also incorporated into this proposed project would be a geomorphic assessment to aid in the design of the project and acquisition of easements along the corridor.
OutcomeStabilized streambanks with bioengineering and hard armoring where necessary to reduce erosion potential; riparian zone with native vegetation that provides near-stream habitat and that reduces pollutant contribution from runoff; enhanced fish and macroinvertebrate habitat.
Estimated Cost and FundingGeomorphic analysis, easement acquisition, permitting, construction, vegetation management contract, and project management. Funding source is the District capital levy.$844,600

ProjectPainter Creek Stream Restoration Phase II
DescriptionRestoration of 2,400 feet of Painter Creek to stabilize streambanks, manage riparian vegetation, and improve in-stream habitat
NeedThe Upper Watershed Stream Assessment identified several areas of erosion on Painter Creek, many of which were concentrated in Reach 1 from Jennings Bay to Painter Creek Drive. The subreach between Painter Road and West Branch Road, approximately 2,400 feet in length, is in similar condition to the subreach in Phase I but the streambanks are less steep and there is less scour potential. Restoration of this segment, ?Phase II,? would include streambank restoration, fish and macroinvertebrate habitat improvements, and buffer restoration. Also incorporated into this proposed project would be a geomorphic assessment to aid in the design of the project and acquisition of easements along the corridor.
