sedimentation in County roadside ditches. These combined efforts allow PW to keep the current <br />paved roadway network from slipping back to gravel (REHABILITATION/REPLACEMENT). <br />Decreasing PRESERVATION efforts will annually place more roads into "rehabilitation" status <br />and ultimate decline leads to "replacement" status. PRESERVATION is essentially maintaining <br />the status quo. It is important to note, that this ten-year TAMP contemplates very little capacity <br />building of new infrastructure and focuses on maintaining what we have currently on the road and <br />bridge network. For the ten-year TAMP the PRESERVATION service level presumes all bridges <br />remain in asset inventory. PRESERVATION will necessitate a voter lift of the Road Levy. <br />Insufficient funding of PRESERVATION efforts necessitates divesting of assets. In the case of <br />Public Works' infrastructure, this means closing bridges and allowing paved roads to deteriorate <br />back to gravel (REHABILITATION/REPLACEMENT). As a means of controlling the loss of <br />inventory, Public Works recommends the public identify a critical roadway network that manages <br />the inevitable decline of assets and reduction of paved road inventory — in the absence of additional <br />revenue. The reduction of road inventory scenario maintains functional class prioritization of <br />arterials and collectors. Local access is assumed to be expendable as a paved road asset. Network <br />wide roadway service levels will decrease as efforts are made to stabilize the prioritized paved <br />road network. As decisions are made to abandon duplicative roads (north -south and east -west), <br />associated bridges will drop off the County's asset inventory associated with those abandoned <br />roads. Bridges represent the largest one-time expenditures to the Road Fund. The asset reduction <br />scenario (REHABILITATION/REPLACEMENT) removes those bridges associated with local <br />roadways slated to return to gravel. Local road pavement reductions generate the retained tax <br />funding needed to preserve the priority road network of arterials and collector roadways. <br />Kittitas County Department of Public Works 2022-2032 Transportation Asset Management Plan <br />Janaury 2022: Page 9 <br />
