CHAPTER THREE: LEVELS OF SERVICE <br />Recognizing the significance of voting a near doubling of Road Fund levy from property tax <br />increases, PW has prepared this ten-year TAMP. This ten-year plan is expected to set <br />transportation service levels and associated expectations for service, at reduced financial impact <br />as forecast in the twenty-year plan. Maintaining current levels of service (2021) with associated <br />revenue increases (PRESERVATION) and reducing assets consistent with no levy increase <br />(REHABILITATION/REPLACEMENT) - provide the two options for funding consideration. <br />The ten-year plan evaluates bridge overall sufficiency ratings and specifically looks at deck <br />element ratings to forecast probable maintenance, PRESERVATION, and replacement costing. <br />Roads are now evaluated for PRESERVATION or REHABILITATION/REPLACEMENT. The <br />two levels of asset condition are directly related to cost. Typically, preserving an asset is the most <br />cost-effective approach followed by REHABILITATION/REPLACEMENT. The often -used <br />analogy is changing your oil in your car or buying a new motor. What is critical to recognize is <br />that failure in meeting PRESERVATION targets for roads and bridges results in exponential <br />increases in costs as the asset tend towards replacement. Federal and State transportation <br />guidelines dictate closure actions of bridges by local government — directly tied to asset decline. <br />Any level of service discussion necessitates assigning priorities for asset protection. Public <br />transportation road networks are assigned significance using the Federal Highway <br />Administration designation system: Federal Functional Classification. Roads are identified as <br />increasingly important based on frequency of use: travel demand and associated average daily <br />traffic. Rural systems (county) are assigned in order of importance to travelers as: Local Access <br />(neighborhood roads), Minor Collectors (multiple neighborhoods), Major Collectors (regional <br />areas) and Minor Arterials (multiple areas). Specific road examples of classification are Cooke <br />Canyon Road (Local), Cabin Creek Road (Minor Collector), and Cove Road (Major Collector). <br />The County has no Minor Arterials on the existing County Road network (not surprising given <br />current County population). The Public Works Department maintains a "County Road Log" of <br />every road owned or maintained by the -County. The log is updated annually reflecting changes <br />in average daily traffic and/or new road construction. A robust traffic counting system enables <br />the annual amendment. What we do not have is a community driven system for prioritizing local <br />roadways for preservation. Pursuing a level of service REHABILITATION/REPLACEMENT <br />necessitates prioritizing local roadways for PRESERVATION. Implementing the <br />REHABILITATION/REPLACEMENT service level will require a reduction of local roadway <br />maintenance. This plan does not address this future need, should County residents elect to adopt <br />a declining level of service on its road network moving away from PRESERVATION towards <br />REHABILITATION/REPLACEMENT. <br />Kittitas County Department of Public Works 2022-2032 Transportation Asset Management Plan <br />Janaury 2022: Page 5 <br />
