Our Goal Prioritized System Approach Integrated Process: Annual Budget Development Dam Safety & Readiness Program Communications Strategy Early & robust stakeholder coordination Tentative Extended NavLock outage: after 2016 Target: 2017, subject to funding availability

CSRS Requirements Prioritization Risk-informed decision process System reliability considerations Requirements list: Portland/Walla Walla Districts & Northwestern Division Periodic team meetings to review the list Reprioritized with new information/condition changes Addition of new or deletion of completed projects

The Columbia-Snake Inland Navigation Bonneville Miter Gates The Dalles Downstream gate NavLock Controls Upstream Gate

2011: New Gate Issues during break-in The Dalles Downstream Navigation Lock Gate Gudgeon bushing failures, gate vibration. 2012: Temporary repair for gudgeon bushing 1 replaced in December 2012 emergency lock outage Remaining 3 replaced during March 2013 lock outage 2013: Design Documentation Report Determine permanent gudgeon bushing repair Investigate gate vibration Determine corrosion control system Investigate gudgeon anchor replacement

Bonneville Downstream Navigation Lock Gate 2011: D/S Miter Gate inspection Skin plate/stiffener: quoin cracks Emergency repairs to strengthen pintle Gate no longer miters until fully loaded 2012: Gate fully instrumented Inspection: no further pintle corner cracking Resolving Remote monitoring challenges 2013: ROV inspection Corner stiffening seems to be performing well

Coordination Objectives CSRS maintenance/recapitalization with available funds Integrate into NWD budgeting process Coordination with PNWA & other stakeholders Use Inland Marine Transportation Improvement Report

Mouth of the Columbia River (MCR) Jetties Sand Island pile dikes 1930-1935 Columbia River Estuary Jetty A 1.6 miles long, 1938-39 Clatsop Spit Peacock Spit North Jetty 2 miles long, 1914-1917 Pacific Ocean South Jetty 6 miles long 1885-1913

BUILDING STRONG

FY 13: South Jetty (O&M) Dune Stabilization South Jetty Root & Trestle Bay: $5.5M Detailed Design Report, P&S, dynamic cobblestone revetment construction

South Jetty Dune Stabilization FY 13 milestones 28 June Contract Award 12 July Notice to Proceed 29 July Begin construction 11 October Complete construction

FY 14 PBUD: Jetty A Major Rehab (CG) - $1M Detailed Design Report, initiate P&S, Mitigation Plan, and physical modeling for head stabilization Based on Major Rehabilitation Report approved June 2012 Jetty A, Oct. 2012

MCR North Jetty FY 14 Capability (O&M) Two separate actions supported by the Major Maintenance Report: (1) Lagoon Fill: $10.32M (2) Critical Repairs: $13.25M Critical Repairs STA 86-99 Lagoon Fill

North Jetty Lagoon Fill (O&M, $10.32M capability) Redirects overland flow away from the jetty structure Dissipates flow into a constructed sump Places gravel, sand and quarry stone on the landward side of the jetty to eliminate the tidal flow through the jetty All three actions will stabilize the North Jetty Root and its foundation Stabilization Areas Oct. 2012

MCR Jetties Future work beyond FY 14 Jetty A, North Jetty, and South Jetty rehabilitation (CG funding) Seven-year construction plan developed in the FY 12 Major Rehabilitation Report supporting $257.2M in jetty repairs (Approximately $31M for Jetty A, $79.8M for the North Jetty and $146.4M for the South Jetty Major Rehab Report actions support measures that will prevent frequent and costly emergency repairs in the future.
