Transcription

1 FACT SHEET Title of Proposal Pierce County Flood Control Zone District Comprehensive Plan of Development Nature and Location of Proposed Action Pierce County Flood Control Zone District is developing a long-term plan to guide river management on the Puyallup, White, Carbon, and Nisqually rivers, as well as the tributary Greenwater and Mashel rivers and South Prairie Creek. The Comprehensive Plan of Development identifies and recommends regional programs and projects related to flooding and channel migration to: 1) reduce risks to public health and safety, 2) reduce public and private property damage, and 3) reduce facility maintenance costs. The proposed CPOD focuses on the main stems of major rivers in Pierce County, including the lower reaches of other large rivers with historical peak streamflows over 5,000 cubic feet per second (cfs). Five thousand (5,000) cfs is the threshold at which a river or stream may have a channel migration zone. The approximate extents of the rivers are described in the following: Puyallup River System: Lower, Middle, Upper (from Commencement Bay at River Mile [RM] 0.0 to Champion Bridge at RM 29) The Lower Puyallup River from the mouth at Commencement Bay (RM 0.0) to the confluence of the White River (RM 10.3) The Middle-Puyallup River from the confluence of the White River (RM 10.3) to the confluence of the Carbon River (RM 17.4) The Upper Puyallup River from the confluence of the Carbon River (RM 17.4) to Champion Bridge (RM 29.0) White River System: Lower, Upper, and Greenwater River The Lower White River from its confluence with the Puyallup River (RM 0.0) to the King/Pierce County boundary (RM 5.5) The Upper White River near the community of Greenwater (RM 42.3 to RM 50.5) The Greenwater River from its confluence with the White River (RM 0.0) to approximately RM 4.0 Carbon River System: Carbon River and South Prairie Creek The Carbon River from its mouth at the Puyallup River (RM 0.0) to approximately the intersection of Alward Road and 245th Avenue East (RM 8.4) The South Prairie Creek River from its confluence with Carbon River (RM 0.0) to the Town of South Prairie (RM 6.4) and RM 22 to RM 24.

2 Nisqually River System: Middle, Upper, and Mashel River The Middle Nisqually River in the McKenna area (RM 21.3 to RM 26.0) The Mashel River from its confluence with Nisqually River (RM 0.0) to the Town of Eatonville (RM 6.8) The Upper Nisqually River from the community of Elbe (RM 50.5) to Mt. Rainier National Park (RM 65.8) Proponent Pierce County Flood Control Zone District Date of Implementation The Board of Supervisors is expected to approve the proposed CPOD in September Implementation of programs and capital projects recommended by the CPOD would occur in years subsequent to plan approval.
