In conformance with replaced in 2020-2021 by the Federal Highway that schedule, Jefferson County completed the Administration Western Federal Lands Division, biennial inspections for all East Jefferson County and is being funded entirely by a Federal Lands bridges in 2019.The completed inspection Access Program grant. reports were submitted to WSDOT, which verifies compliance with the NBIS and reports to the Federal Highway Administration (FHWA). �. • DEFICIENT BRIDGES • ., All bridges are assigned a sufficiency rating (SR), which is a calculated score based on numbers �� ��, � assigned to all of the bridge elements reviewed ifs by the bridge inspector. The SR is a number fromj�,,, 0 to 100, with 100 being an entirely sufficient bridge, and 0 being an entirely insufficient bridge. -,- . ' ` For additional explanation of the sufficiency " ' `' -tite rating and other ratings see the attached WSDOT Tower Creek Bridge publication, Bridges and Structures—Ratings (Appendix B). The sufficiency rating is used POSTED BRIDGES to determine if a bridge is eligible for federal rehabilitation or replacement funding. Under All bridges are required to have a "Load Rating" the current funding requirements, to be eligible calculation. The Load Rating establishes how for replacement a bridge must be structurally much weight the bridge can carry for several deficient and have a sufficiency rating of less standard configurations of vehicle axle loads. If than 40; to be eligible for rehabilitation a the load rating calculation shows that a bridge bridge must be structurally deficient and have a cannot safely carry one or more of the legal sufficiency rating of less than 80. Currently, none vehicle axle load configurations, then the bridge of the county's bridges meet these criteria, and must be posted with the appropriate load limits. therefore none are eligible for rehabilitation or Jefferson County currently has two bridges that replacement. require load posting, Meyers Bridge on Belfrage Road and Hemphill Creek Bridge on Dowans As described in previous Bridge Condition reports, Creek Road.

Fish Passage Program grant (approx. 10%), and local funds (approx. 5%). MAINTENANCE ACTIVITIES t, a,. . Routine maintenance of the county's bridges is �,�� `�� i"�' conducted by the road maintenance department. }a� 4 � Typical routine maintenance consists of deck cleaning, brush clearing, and minor miscellaneous :.- .� repairs. In April 2019, the County applied for$90,830 in Bridge Replacement Advisory Committee (BRAC) I funds for a preventative maintenance project on the Hurst Creek Bridge, Clearwater Road milepost 2.66. The Hurst Creek Bridge has concrete girders with steel diaphragms between the girders at mid-span. The steel diaphragms are in need of Wally Bowman Bridge repainting or replacement. In September 2019 we learned the project would not be funded through BRAC, so an alternative funding source will need CURRENT PROJECTS to be found. Current projects include the following: Upper Hoh Road/Olympic National Park Federal Lands Access Program (FLAP) Project: • Design is nearly complete on a new 120 ft. long concrete bridge to replace the existing bridge at Tower Creek, Upper Hoh Road milepost 7.5. This project is being managed by the Federal Highway Administration Western Federal Lands Division, and is funded entirely by a FLAP grant. Construction is scheduled for 2021-2022.

WMII Department o/Transportation Bridge Ratings The safety of bridge structures in Washington State is ensured through a meticulous inspection system. All public bridge owners, such as WSDOT, Counties and Cities, follow the same bridge inspection procedures. The condition rating of all bridge ,� decks, superstructures and substructures and other elements � ; ;, based on these inspections. , USDOT's Federal Highway Administration (FHWA) requires all public bridge owners (state, city, and county ) to inspect and . their bridges and report information including bridge condition ratings as part of their requirements in the National Bridge Inventory Standards (NBIS). Important aspects of the NBIS were: 1. All states SR20 Deception Pass Bridge must 1 1` perform periodic inspections . of bridges greater than 20 feet in span on at least a biennial SR6 Wiliapa River bridge basis. 2. Data collection was standardized and must be reported to FHWA. 3. Qualifications for inspection personnel were defined. 4. Training programs were developed and implemented. 5. The Bridge Replacement Program (BRP) was established to provide funding for bridge replacement on the system. Structurally Deficient Structurally deficient means that a bridge requires repair or replacement of a certain component. This may include cracked or spalled concrete, the bridge deck, the support structure, or the entire bridge itself. If the condition is such that it no longer is able to carry its intended traffic loads it may be weight restricted. Being structurally deficient does not imply that the bridge is in danger of collapse or unsafe to the traveling public. If a bridge is open then it is considered safe. A bridge is classified as"Structurally Deficient"when bridge inspectors give either the superstructure, deck, and/or substructure a rating of four or less on a scale of zero to nine. WSDOT's poor condition category uses the same data, criteria, and rating scale. http://www.wsdot.wa.gov/Bridge/Reporting/BridgeRatings.htm 8/14/2015 WSDOT - Bridges and Structures - Ratings Page 2 ofi WSDOT has 137 state owned bridges that are classified as structurally deficient v 1 ; as of Jan. 2015. A list of these bridges is available in pdf and web page and �' _ . map format. Functionally Obsolete Functional obsolescence is assessed by comparing the existing design of each bridge to current standards. A bridge can be categorized functionally obsolete a number of ways including: ' * , substandard bridge widths, low vertical clearance that can lead to repeated damage from over height trucks, load-carrying capacity, or flood potential. Interstate 82 Columbia River bridge near Umatilla There are 866 WSDOT bridges that are rated"Functionally Obsolete" Good, Fair, Poor Condition Rating Good: A range from no problems to some minor deterioration of structural elements. Fair: All primary structural elements are sound but may have deficiencies such as minor section loss, deterioration, cracking, spalling, or scour. Poor: Advanced deficiencies such as section loss, deterioration, cracking, spalling, scour, or seriously affected primary structural components. Bridges rated in poor condition may be posted with truck weight restrictions. A summary of the WSDOT bridge network conditions is available in the 2014 Bridge Annual Report in the Gray notebook. Copyright WSDOT© 2015 http://wu-w.wsdot.wa.gov/Bridge/Reporting/BridgeRatings.htm 8/14/2015 VDIar Bridge inspection Definitions What are "general condition ratings?" According to the National Bridge Inspection Standards (NBIS), condition ratings are used to describe an existing bridge or culvert compared with its condition if it were new. The ratings are based on the materials, physical condition of the deck (riding surface), the superstructure (supports immediately beneath the driving surface) and the substructures (foundation and supporting posts and piers). General condition ratings range from 0 (failed condition) to 9 (excellent). For detailed definitions, click here. Which bridges are included in the NBI system? NBI structures are bridges or culverts that carry vehicular traffic and have an opening longer than 20 feet measured along the center of the roadway. What bridges are not considered part of the NBI system? Non-NBI structures include bridges or culverts that carry vehicular traffic and are equal to or less than 20 feet measured along the center of the roadway. VDOT exceeds the NBI standards by inspecting and documenting in our inventory all bridges regardless of their length and all culverts having an opening greater than 36 square feet. What is a "structurally deficient" bridge? Bridges are considered structurally deficient if they have been restricted to light vehicles, closed to traffic or require rehabilitation. Structurally deficient means there are elements of the bridge that need to be monitored and/or repaired. The fact that a bridge is "structurally deficient" does not imply that it is likely to collapse or that it is unsafe. It means the bridge must be monitored, inspected and maintained. How is "structural deficiency" determined? The condition of different parts of a bridge is rated on a scale of 0 to 9 (with 9 being "excellent" and zero being "failed"). A structurally deficient bridge is one for which the deck (riding surface), the superstructure (supports immediately beneath the driving surface) or the substructure (foundation and supporting posts and piers) are rated in condition 4 or less. What makes a bridge structurally deficient, and are structural deficient bridges unsafe? The fact that a bridge is "structurally deficient" does not imply that it is likely to collapse or that it is unsafe. A "deficient" bridge is one with some maintenance concerns that do not pose a safety risk. A "deficient" bridge typically requires maintenance and repair and eventual rehabilitation or replacement to address deficiencies. To remain open to traffic, structurally deficient bridges are often posted with reduced weight limits that restrict the gross weight of vehicles using the bridges. If unsafe conditions are identified during a physical inspection, the structure must be closed. What is a "functionally obsolete" bridge? A functionally obsolete bridge is one that was built to standards that are not used today. These bridges are not automatically rated as structurally deficient, nor are they inherently unsafe. Functionally obsolete bridges are those that do not have adequate lane widths, shoulder widths, or vertical clearances to serve current traffic demand, or those that may be occasionally flooded. A functionally obsolete bridge is similar to an older house. A house built in 1950 might be perfectly acceptable to live in, but it does not meet all of today's building codes. Yet, when it comes time to consider upgrading that house or making improvements, the owner must look at ways to bring the structure up to current standards. What is a "fracture-critical" bridge? A fracture-critical bridge is one that does not contain redundant supporting elements. This means that if those key supports fail, the bridge would be in danger of collapse. This does not mean the bridge is inherently unsafe, only that there is a lack of redundancy in its design. What is a bridge's "sufficiency rating?" Sufficiency ratings were developed by the Federal Highway Administration to serve as a prioritization tool to allocate funds. The rating varies from 0 percent(poor) to 100 percent (very good). The formula considers structural adequacy, whether the bridge is functionally obsolete and level of service provided to the public. History of Federal Bridge Inspection Program The federal bridge inspection program regulations were developed as a result of the Federal-Aid Highway Act of 1968 following the collapse of the Silver Bridge in Point Pleasant, West Virginia. The United States Secretary of Transportation established the National Bridge Inspection Standards (NBIS) to locate and evaluate existing bridge deficiencies to ensure the safety of the traveling public. The 1968 Federal-Aid Highway Act directed the states to maintain an inventory of federal-aid highway system bridges. This was amended over time to establish criteria for NBIS bridges including: • Defining the NBIS to bridges to those on the federal-aid highway system • Requiring inspections of bridges longer than 20 feet on all public roads • Expanding bridge inspection programs to include special inspection procedures for fracture- critical members and underwater inspection Bridge ( andition Code key Code Description N NOT APPLICABLE 9 EXCELLENT CONDITION 8 VERY GOOD CONDITION No problems noted. 7 GOOD CONDITION Some minor problems. 6 SATISFACTORY CONDITION Structural elements show some minor deterioration. 5 FAIR CONDITION All primary structural elements are sound but may have some minor section loss (due to corrosion), cracking, spalling (deterioration of concrete surface) or scour (erosion of soil) 4 POOR CONDITION Advanced section loss, deterioration, spalling or scour. 3 SERIOUS CONDITION Loss of section, deterioration, spalling or scour have seriously affected primary structural components. Local failures are possible. Fatigue cracks in steel or shear cracks in concrete may be present. 2 CRITICAL CONDITION Advanced deterioration of primary structural elements. Fatigue cracks in steel or shear cracks in concrete may be present or scour may have removed substructure support. Unless closely monitored it may be necessary to close the bridge until corrective action is taken. 1 "IMMINENT" FAILURE CONDITION Major deterioration or section loss present in critical structural components or obvious vertical or horizontal movement affecting structure stability. Bridge is closed to traffic but corrective action may put back in light service. 0 FAILED CONDITION Out of service - beyond corrective action. Department of Public Works O Regular Agenda: 10:00 AM Page 1 of 1 Jefferson County Board of Commissioners Agenda Request To: Board of Commissioners Philip Morley, County Administrator From: Monte Reinders, PE, Public Works Director/County Engin Agenda Date: November 12, 2019 // Subject: Adoption of 2020-2025 Six-Year Transportation Improvement Program (TIP) Statement of Issue: Conduct a public hearing for the purpose of receiving public testimony concerning adoption of the 2020-2025 Jefferson County Six-Year Transportation Improvement Program (TIP). Analysis / Strategic Goals / Pros &t Cons: RCW 36.81.121 requires the annual adoption of a six-year transportation improvement program after holding a public hearing. The purpose of the law is to "assure that each county shall perpetually have available advanced plans looking to the future for not less than six years as a guide in carrying out a coordinated transportation program" (RCW 36.81.121(1)). Fiscal Impact / Cost-Benefit Analysis: The TIP is a planning document and identifies the likely availability of outside grant and program funding from the State and Federal government, and local revenues. Fiscal impact is evaluated through the annual budgeting process including adoption of an Annual Construction Program. Recommendation: After considering public testimony, approve by Resolution the proposed Six-Year Transportation Improvement Program. Return a signed copy of the resolution to Public Works for further processing.
