Department of Public Works O Regular Agenda: 1:30 PM Page 1 of 1 Jefferson County Board of Commissioners Agenda Request To: Board of Commissioners Philip Morley, County Administrator From: Monte Reinders, Public Works Director/County Enginee� Agenda Date: November 20, 2017 Subject: Briefing of the Proposed 2018-2023 Six -Year Transportation Improvement Program Statement of Issue: Public Works Director/ County Engineer, Monte Reinders and Engineering Services Manager, Eric Kuzma to brief the Board of County Commissioners of the upcoming public hearing and proposed adoption of the 2018-2023 Jefferson County Six -Year Transportation Improvement Program (TIP). Analysis / Strategic Goals / Pros 8t 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 relies heavily on the availability of outside grant and program funding from the State and Federal government. Fiscal impact is evaluated through the annual budgeting process including adoption of an Annual Road Construction Program. Recommendation: No action required.

Public Works Director/County Engineer Welcome to the 2018-2023 Six -Year Transportation Improvement Program (T.I.P.). The Six -Year T.I.P. is a "rolling" plan that is updated each year to provide direction to transportation improvements on Jefferson County's 400 -mile public road system. Development of the T.I.P. is a process that identifies needs, prioritizes those needs, develops projects to meet the needs, and rolls prioritized projects into a plan intended to occur over the next six years. A range of different project types is included in the T.I.P. The T.I.P. is strongly influenced by the availability of funding, and many of the projects listed do not, as yet, have secured funding. Historically, projects on Jefferson County's T.I.P. have averaged more than 70% funding from State and Federal sources. Many non -local transportation revenue sources however only fund certain types of improvements on certain types of roads, and as such Federal and State priorities can strongly influence what actually gets accomplished. Lack of available local match funds limits the number and size of grants that can be utilized. Local funds available for this proposed 6 -year capital program average only $277,000 per year. Jefferson County has a limited tax base with transportation revenues among the lowest in western Washington when measured in terms of dollars available per road mile. The county road fund has seen a 25% overall reduction in annual operating revenue due to loss of federal land timber revenue in recent years. As a result, road fund reserves are drawn down more and more each year. The Six -Year T.I.P., like any other capital improvement plan is only a plan for what should be done, provided adequate funding is available. It shows what funding must be sought and/or what revenue sources must be developed. Decisions about which projects actually get advanced are made through the annual County budgeting process. Since the Six -Year T.I.P. is updated annually, it can be changed to reflect new needs, priorities, and changed budgetary conditions. I hope you find this document useful in understanding Jefferson County's Transportation Improvement Program. If you would like more information, feel free to contact the Jefferson County Public Works office, located at 623 Sheridan Street, at (360)385-9160. Monte Reinders, P.E.

Public Works Director/County Engineer FROM: Monte Reinders, P.E., Public Works Director/County Engineet�A/2__ DATE: November 1, 2017 SUBJECT: Bridge Condition Report 2017 INTRODUCTION As required by WAC 136-20-060, each county engineer shall furnish the county legislative authority with a written report of the findings of the bridge inspection effort. This report shall be made available to said authority and shall be consulted during the preparation of the proposed six- year transportation program revision. The report shall include the county engineer's recommendations as to replacement, repair or load restriction for each deficient bridge. The resolution of adoption of the six-year transportation program shall include assurances to the effect that the county engineer's report with respect to deficient bridges was available to said authority during the preparation of the program. BRIDGE INVENTORY Jefferson County Public Works has 32 active bridges — see the attached Master Bridge List (Appendix A) for a listing of the county bridges. Jefferson County also has two permanently closed bridges, which are not listed on the Master Bridge List. BRIDGE INSPECTIONS The National Bridge Inspection Standards (NBIS) and WAC 136-20-030 mandate that public agencies inspect and report on all bridges at least once every two years (routine inspection). Jefferson County staff performs all routine inspections. Special inspections are required for bridges that cannot be inspected adequately from the ground. For these bridges an Under -Bridge Bridge Condition Report 2016 Page 1 of 4 17 Inspection Truck (UBIT) is required. Steel bridges with fracture critical members may also require special inspections with the UBIT and/or other special equipment. Jefferson County has two bridges which require the UBIT inspection and one bridge which requires both the UBIT and the fracture critical inspection (identified in the attached Master Bridge List). Jefferson County currently has a contract with the Washington State Department of Transportation (WSDOT) to perform these inspections. Jefferson County Public Works has split up the bridge inspections so that East Jefferson County bridges are inspected in odd -numbered years and West Jefferson County bridges are inspected in even -numbered years. In conformance with that schedule, Jefferson County completed the biennial inspections for all East Jefferson County bridges in 2017, with the exception of the Contractor's Creek Bridge, which was inspected by WSDOT with the UBIT in July 2016. The completed inspection reports were submitted to WSDOT, which verifies compliance with the NBIS and reports to the Federal Highway Administration (FHWA). FEDERAL AUDIT In July 2017, FHWA and WSDOT conducted an office and field review of Jefferson County's bridge inspection program. The office review consisted of reviewing the County's individual bridge files for consistency with state and federal requirements. The office review resulted in some minor needed corrections, which are being addressed. The field review consisted of federal and state bridge inspection personnel conducting mock bridge inspections on two of the county's bridges, and comparing their findings with the county's bridge inspection reports for those bridges. The field review resulted in no needed corrections. 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 by the bridge inspector. The SR is a number from 0 to 100, with 100 being an entirely sufficient bridge, and 0 being an entirely insufficient or deficient bridge. For additional explanation of the sufficiency rating and other ratings see the attached WSDOT publication, Bridges and Structures — Ratings (Appendix B). The sufficiency rating is used to determine if a bridge is eligible for federal rehabilitation or replacement funding. Currently, none of the county's bridges have any major deficiencies, and none are eligible for rehabilitation or replacement. As described in previous Bridge Condition reports, the Tower Creek Bridge is being monitored for potential scour problems associated with down -cutting of the streambed. The Tower Creek streambed experienced significant down -cutting in 2007-2008 due to migration of the Hoh River and heavy flows in Tower Creek. However, based on regular monitoring, the streambed elevation has been relatively stable since 2008. Public Works will continue to monitor this situation. Plans for replacement of the Tower Creek Bridge are in the preliminary engineering phase. This project is being managed by the Federal Highway Administration Western Federal Lands Division, and is being funded completely by a Federal Lands Access Program grant. Bridge Condition Report 2016 Page 2 of 4 18 POSTED BRIDGES All bridges are required to have a "Load Rating" calculation. The Load Rating establishes how much weight the bridge can carry for several standard configurations of vehicle axle loads. If the load rating calculation shows that a bridge cannot safely carry the legal traffic loads then the bridge must be posted with the appropriate load limits. Jefferson County currently does not have any bridges with load restrictions. The load rating values (in tons) are listed on the attached Master Bridge List (Appendix A). A 2013 FHWA mandate requires that all bridges be load rated for a relatively new class of vehicle, the Specialized Hauling Vehicle (SHV). SHV's are closely -spaced multi -axle single unit trucks introduced by the trucking industry in the last decade. Examples include dump trucks, construction vehicles, solid waste trucks and other hauling trucks. The FHWA has divided bridges into two categories, with the first category requiring updated load ratings by December 31, 2017, and the second category requiring updated load ratings by December 31, 2022. Jefferson County is currently finalizing load ratings for three bridges for the 2017 deadline. An additional twenty-two bridges will need to be re -load rated prior to the 2022 deadline. It is possible that some Jefferson County bridges will need to be load posted for SHV's after the load rating results are known. OBSOLETE BRIDGES The Old Little Quilcene Bridge and the Maple Creek Bridge have been placed in obsolete status and removed from the Master Bridge List. Both are permanently closed to vehicular traffic. This action removes the requirement for biennial bridge inspection. EMERGENCY REPAIRS AND INSPECTIONS In June 2017, a minor repair was performed at Meyers Creek Bridge on Belfrage Road, where a void was discovered under the asphalt in the westerly approach to the bridge. The void was filled in and the surfacing was repaired. MAINTENANCE ACTIVITIES Routine maintenance of the county's bridges is conducted by the road maintenance department. Typical routine maintenance consists of deck cleaning, brush clearing, and minor miscellaneous repairs. COMPLETED PROJECTS Completed projects include the following: • A new bridge was added to the system in the summer/fall of 2016. At an unnamed tributary to the Hoh River at Upper Hoh Road MP 6.95, a 21 ft. span, pre -cast, reinforced concrete three -sided structure was constructed. This project replaced an under -sized Bridge Condition Report 2016 Page 3 of 4 IN culvert where gravel has plugged and spilled out over the roadway numerous times in the past. The new bridge also corrected a fish -passage barrier. The project was funded with 100% funding from the Federal Highway Administration. An 80 ft. span steel pedestrian bridge was installed over Chimacum Creek as part of the Rick Tollefson Memorial Trail project. This project is expected to be complete in November 2017. The pedestrian bridge will be added to Jefferson County's bridge inventory and inspected on a routine basis, but will not be reported to WSDOT and FHWA, as pedestrian bridges are not part of the federal bridge inspection program. CURRENT PROJECTS Current projects include the following: • An 80 foot span concrete bridge on West Uncas Rd MP 0.804 is in the final design phase. Construction is scheduled for 2018. This project is being funded by a Salmon Recovery Funding Board grant (approx. 85%), a National Fish Passage Program grant (approx. 10%), and local funds (approx. 5%). PROGRAMMED PROJECTS There are no programmed bridge projects at this time. RECOMMENDED PROJECTS There are no recommended bridge projects at this time.

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 must perform periodic inspections of bridges greater than 20 feet in span on at least a biennial basis. SR6 Wiliapa River bridge Page 1 of 2 SR20 Deception Pass Bridge 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 28 WSDOT - Bridges and Structures - Ratings WSDOT has 137 state owned bridges that are classified as structurally deficient 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. There are 866 WSDOT bridqes that are rated "Functionally Obsolete" Page 2 of Interstate 82 Columbia River bridge near Umatilla 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.

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 e. ua al 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) orthe 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. 30 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 31 Bridge audition 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. "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. 32
