Description    


The Greater Oregon City Watershed Council (GOCWC) proposes to develop a set of construction-ready design products that will enable for future restoration of instream and riparian habitats over approximately 0.15 miles of Holcomb creek through placement of large wood in the channel. The project location is on Holcomb Creek 0.2 miles upstream from its confluence with Abernethy Creek. Stream inventories conducted in 2017 and 2019 indicated a lack or large wood and associated complex habitat throughout the Abernethy Creek watershed. Preparation of final engineering drawings and construction level contracting documents for project implementation will be accomplished. The project tasks include completing necessary hydraulic modeling and data analysis in support of the designs, developing 60% design and associated drawings for regulatory permitting, and finalizing design and drawings with an engineer’s cost estimate for construction.

Project Benefit    


The project will benefit salmon and steelhead through development of a construction ready design that will pave the way for the proposed restoration measures to be implemented. The design completed under this grant will allow for regulatory authorizations to be secured and construction to take place during the established in-water work period. The project design will focus on establishing the conditions necessary to create and maintain complex instream habitat as well as improve riparian conditions that provide shading and long-term recruitment potential for wood in the stream.
