NATURAL WATERS Hungry Junction lmprovement Proiect lune 4,2025 of the site, including photographs taken during the site reconnaissance. The memo will include key hydraulic information needed for permit application. Assumptions: . Up to 60 hours for a Principal and 8 hours for an Administrative Assistant are available for Task 2.7. o A draft version of the memo will be provided to KCPW for review and one set of combined comments. Task 2.8 Final Hydraulic Basis of Design Memo Upon concurrence of resolution of comments from the draft memo (Task 2.7) and obtaining permits, the memo will be finalized. The scour analysis (Task 2.5) based on the geotechnical and structure information provided by KCPW and updates from permitting will be incorporated into the Final memo. Assumptions: o A draft version of the Final memo will be provided to KCPW for review and one set of combined comments. . Up to 20 hours for a Principal and 4 hours for an Administrative Assistant are available for Task 2.8. Task 2.9 Channel, LWM and Revelment Design Natural Waters will design the proposed channel, LWM and revetment necessary for the Hungry Junction water crossing. The design will allow for natural stream processes to the extent practicable given project constraints (e.g., ROW, adjacent infrastructure, project costs, etc'). The design will focus on creating a sustainable creek cross section, profile, and alignmenU which will aim to reduce future maintenance while providing suitable habitat for aquatic organisms based on WDFW criteria. Calculations will be provided in the Final memo (Task 2.8). Assumptions: o The channel, LWM and revetment design will only be in the vicinity of the Hungry Junction water crossing. Transitions will be discussed with KCPW to tie into the existing banks upstream and downstream of the project limits provided by KCPW. o The Reecer Creek design will have similar geomorphic features (e.g', creek substrate) as the upstream and downstream reaches of Reecer Creek. o lt is assumed that any scour/bank protection will consist of a rock revetment with potential incorPoration of LWM. e All CAD work and plan sheet development will be performed by KCPW staff. . Up to 24 hours are available for Task 2.9. 4lPage
