Chehalis River Basin Flood Authority Education and Outreach

Chehalis River Basin Flood Authority Education and Outreach Subcommittee Actions and Activities Benefiting the Basin February 2013

Today’s Presentation n Raise awareness n Encourage discussion n Key messages we’d like to leave you with. . . 1. Broad agreement -- For the first time in a century there is broad agreement on the next steps to reduce flood damage and enhance salmon runs in the Basin. 2. Basin-wide strategy -- A Basin-wide strategy can protect communities along the river and enhance salmon runs. 3. Flood Authority – Positioned to continue to be a galvanizing force in the Basin for implementation of tools, and projects. n Discussion Feb. 2013 2

Chehalis River Basin Flood Authority n Formed in 2008 n Formal body focused on (1) flood hazard mitigation throughout the Basin and (2) decisions that would be. . . q informed by science q protective of Basin residents/communities q environmentally appropriate n Basin jurisdictions represented Grays Harbor County City of Centralia City of Napavine Lewis County City of Chehalis City of Oakville Thurston County City of Cosmopolis Town of Pe Ell City of Aberdeen City of Montesano Town of Bucoda Feb. 2013 3

Background n High flow events. . . l I-5 closed 1990, 1996, 2007, 2009 l Five largest events since 1986 -- Frequent Floods are getting worse and damage is increasing. . . l Chart -- Chehalis River Flow Rates near Grand Mound (cubic ft. /sec. ) 90000 80000 3 70000 60000 50000 40000 6 7 9 13 13 11 4 10 16 1 2 5 8 12 15 30000 20000 19 3 19 2 3 19 4 3 19 6 3 19 8 4 19 0 4 19 2 4 19 4 4 19 6 4 19 8 5 19 0 5 19 2 5 19 4 5 19 6 5 19 8 6 19 0 6 19 2 6 19 4 6 19 6 6 19 8 7 19 0 7 19 2 7 19 4 7 19 6 7 19 8 8 19 0 8 19 2 8 19 4 8 19 6 8 19 8 9 19 0 9 19 1 9 19 3 9 19 5 9 19 6 9 20 8 0 20 0 0 20 2 0 20 4 0 20 6 0 20 8 1 20 0 12 0 Feb. 2013 7

Background n Chehalis is the second largest river basin in the state, rich in natural resources. . . Feb. 2013 8

Need -- Strategy, Tools, Action. . . Strategy = Basin-Wide Solution n Significant reduction of flood damage. n Solving one area’s problems doesn’t increase problems for others. William D. Ruckelshaus Center n Five areas: ü major capital projects ü localized projects ü land use management ü environmental enhancements ü flood warning and emergency response City of Oakville http: //www. oakvillecityhall. com Feb. 2013 9

Tools -- Flood Warning System n www. chehalisriverflood. com n Front-facing website. n Back-end data collection and data synchronization system. n Improves forecasting and early-warning. Feb. 2013 10

Tools -- Flood Warning System n Localized tracking, forecasting. . . Chehalis River near Grand Mound Feb. 2013 11

Tools -- Hydraulic Analysis Model n Science-based model to inform decision-makers on the hydraulic effects of potential flood relief alternatives (at basin-wide and localized scales). n 25 potential flood relief projects or project combinations were analyzed/evaluated with the model. n Covers mouth of the Chehalis River upstream to Pe Ell (108 miles). Feb. 2013 12

Tools -- Hydraulic Analysis Model n Now have analytic ability to understand potential project effects, downstream and up. Feb. 2013 13

Tools -- Hydraulic Analysis Model n Example: Basinwide effects analysis (Chehalis Basin Flood Hazard Mitigation Alternatives Report, 12/2012) Feb. 2013 14

Tools -- Fish Studies n Two significant fish studies conducted in Upper Basin (WRIA 23). 1. Analyze effect of dam alternatives on Spring Chinook, Steelhead and Coho. 2. Prioritize potential fish habitat enhancement opportunities. n Initial projections. . . Species Spring Chinook Multi-Purpose Dam Flood Control. Only Dam Fish Habitat Enhancement Measures 20% � 4% � likely same as Coho Steelhead 7% � 11% � likely same as Coho 1% � Feb. 2013 4 -5% � 15

Action -- 2012 Jobs Now Act Projects n $5, 000 provided under 2012 Jobs Now Act. q $1, 875, 000 -- Repair/modification of levees and dikes. q $2, 075, 000 -- Modification of Sickman Ford bridge, and floodplain culverts. q $50, 000 -- Installation/calibration of rain gauge on Chehalis reservation. q $500, 000 -- Construction of evacuation routes and critter pads. q $500, 000 -- Improvements to areas affected by Satsop river. n Half the funds allocated to date. ü Grays Harbor County ü Adna ü Aberdeen ü Montesano ü Bucoda ü ü WA Conservation Commission Chehalis.

Action -- 2013 Proposed State Capital Budget n Governor workgroup convened to develop prioritized list of projects for 2013 state capital budget based on Basin-wide solution. q Chehalis Tribe q Washington Dairy Federation q Chehalis Flood Authority q Governor’s staff n Proposed budget. . . 1. Construct local flood damage reduction projects now ($10. 7 million) 2. Complete design alternatives for large-scale flood damage reduction projects ($9. 2 million): q Upper basin water retention-engineering and design q I-5 protection options 3. Construct multipurpose projects that reduce flood damage and benefit fish ($4. 3 million) 4. Reduce residential damage ($1. 8 million) 5. Ensure successful implementation ($2. 2 million) Feb. 2013 17

Action -- 2013 Proposed State Capital Budget n Proposed budget ($10. 7 million for local projects). . . http: //goo. gl/maps/g. Wob 9 Feb. 2013 18

Looking Ahead. . . n Continue to focus on local small/mid-scale projects (like was done in 2012 with Jobs Now Act projects). n Major projects: l Upper Basin Dam – Evaluate design alternatives to determine permit feasibility, engineering safety and mitigation requirements by December 2014. l I-5, Airport, Twin Cities – Conduct design and engineering analysis on four protection alternatives. n Continue to improve existing tools (usability improvements to Flood Warning System). n Continue to be a galvanizing force for the Basin.
