Catherine Creek 44 Phase 3 - Southern Cross

  • GRMW ID: 1927
  • Fiscal Year: 2016

The project includes construction of approximately 4,200 linear feet of new main channel (including four confluences with the existing channel); construction/excavation of approximately 955 linear feet of perennial side channel; construction of approximately 425 linear feet of new ephemeral side channel; construction of approximately 1,425 linear feet of alcoves and spring channels; construction of approximately 9,200 linear feet of floodplain swale complexes; construction of 15 riffles in the main channel; construction of 142 main channel wood structure components; construction of approximately 570 linear feet of edge roughness; construction of approximately 1,075 feet of brush mattress; construction/placement of 336 floodplain roughness features (primarily large and small wood structures and whole trees); and the excavation of over 50,000 cubic yards of material (design quantity) over a two year construction period. Design changes from 75% design to 100% design on the CC44, Parcel 3, Southern Cross parcel were incorporated to maximize adult spawning and juvenile rearing habitat uplift along an approximate 0.78 mile reach of mainstem Catherine Creek which was acquired in fee title through the CTUIR-BPA Accord for fish conservation purposes. The property presents the largest and most significant opportunity to expand, create, and enhance core spawning and rearing habitat for ESA spring-summer chinook salmon and summer steelhead within the Catherine Creek Atlas Tier 1 Biological Significant Reach, CCC3a1.
