Project Subcommittee Subcommittee Purpose/Goals: – Develop a master inventory of flood-related projects in the Chehalis Basin Seven sets of discussions: – September 9 – October 4 – October 20 (Flood Authority Workshop) – November 22 – January 13 – February 3 (Conference Call) – March 1

Project Matrix Flood related projects from 15 different flood planning documents. – Chehalis Flood Authority Project List May 2011 – New Projects Proposed by Flood Authority Jurisdictions (11/22/2010) – Confederated Tribes of the Chehalis Reservation CFHMP (3/17/2009) – Chehalis River Basin Draft Comprehensive Flood Management Plan (June 2010) – Centralia Comprehensive Flood Management and Natural Hazards Mitigation (4/2011) – Thurston County Annual Progress Report – Implementing Flood Hazard Mitigation Initiatives in the Natural Hazards Mitigation Plan (8/11/2011) – City of Aberdeen Public Works Master Project List (January 2011) – ACOE Mitigation Projects in the Chehalis Basin – Grays Harbor County Draft Hazard Mitigation Plan 2001 – City of Chehalis from Bob Nacht 10/10/2011 – Lewis County Comprehensive Flood Hazard Management Plan – Grays Harbor County Draft Hazard Mitigation Plan 2011 – Description of Potential Enhancement Projects in Upper Chehalis Watershed – Chehalis Basin Watershed Management Plan – Chehalis Basin Partnership – Multi-Purpose Water Storage Assessment

Proposed Goal of Project Matrix “The purpose of this matrix of projects is to reflect the Chehalis River Basin Flood Authority’s priorities to provide flood relief and protection in the basin.”

Project Matrix Projects sorted into nine different sections – Floodplain Protection (includes retention, and levees/dikes – Reduction of Damage to Existing Structures – Bank Stabilization – Conveyance Capacity – Planning/Implementing and Data Collection – Education and Public Information – Emergency Response and Preparedness – Potential Flood Projects with Ecological Opportunities (includes correcting barrier culverts) – Programmatic Solutions-i.e. regulation changes, tax breaks

Project Matrix Projects may be grouped under a sub heading (“Retention Projects” or “Levees and Dikes” under Floodplain Protection) – In these cases, the project heading is numbered following the project numbering sequence. – Projects under the heading are numbered in Roman Numerals Matrix of projects is not prioritized – Meant to serve as a baseline of projects for potential future funding – Served as source material for 2012 legislative jobs package

Projects to be Removed Matrix Matrix of projects that are proposed to be removed from the Projects Matrix – Repetitive – Completed – Currently funded and on-going – Source of project unknown – No longer a priority

Request to the Flood Authority Provide recommendations on: – 1. Proposed Goal – 2. Overall Approach – 3. Do you have any additional projects for the Project Matrix? – 4. Do you have any additional sources that should be reviewed for additional projects?

More Details for the Project Matrix Upon approval of the approach and scope of the Project Matrix, the goal of the Project Subcommittee will be to add: – More detailed description, including precise location – Estimated cost – Flood benefit – Stage of Readiness
