CHAPTER SIX: REVENUES Road Fund Levy 2011 to 2021 The Road Fund was significantly impacted financially from 2015 to 2019 owing to Levy Shifts authorized by the Board of County Commissioners. From 2013 through 2019, $5.6 million dollars were shifted out of the Road Fund and utilized for other purposes. In 2020, Public Works Administration successfully restored (utilizing banked capacity in the Road Fund) significant funding beginning in 2020 and continuing in 2021. This action is expected to reduce future Levy lift requests meeting selected levels of service. Road Levy revenue history (2012 — 2021) appears as APPENDIX 3 to this plan. TAMP Revenue Forecast Assumptions Local government in the State of Washington may increase tax revenue annually with a cap at one percent per year without taking a larger increase to a vote by county residents. This ten-year TAMP uses 2022 Road Fund Levy revenue and increases it by one percent per year for each year of the study period. 2021 — 2031 Revenue Forecasts appear as APPENDIX 4 of this plan. PW has been extremely successful generating supplemental funding for asset replacement during the previous six years. This ten-year TAMP utilizes our previous ten-year revenue history in supplemental funding and imposes professional judgement to forecast likely supplemental funding during the study period. This forecast is subjective but not without performance experience and incorporates informed decision making based on that experience. The risk of over predicting supplemental revenue, is that PW fails to meet PRESERVATION funding levels and additional REHABILITATION costs require assignment to the plan — reducing service levels. Individual funding sources have been evaluated for continued program performance during the study period. While much discussion has been recently occurring around infrastructure funding, the reality for local government is that a minimal amount of federal spending will make it to the local level. CHAPTER SEVEN: LEVELS OF SERVICE AND RISK 10 Year Service Levels — PRESERVATION versus REHABILITATION/REPLACEMENT Currently, Public Works utilizes pavement management techniques that essentially places a surface wearing course on all paved roads every seven years. This "chip seat' practice results in resurfacing of the roadway wearing course of approximately 70 miles of roadway every year. This is a standard pavement preservation technique utilized by Public Works organizations across the country. Prior to surfacing, the selected roadways are "crack sealed" and "pre -leveled" to reduce roadbed and road subgrade failure. These business practices are consistent with PRESERVATION of the road asset. Maintenance of County roads also includes additional PRESERVATION efforts such as vegetation and drainage maintenance. These activities manage vegetation growth and Kittitas County Department of Public Works 2022-2032 Transportation Asset Management Plan Janaury 2022: Page 8
