KITTITAS COUNTY <br />DEPARTMENT OF PUBLIC WORKS <br />PUBLIC WORKS — BOARD OF COUNTY COMMISSIONERS <br />ENGINEER'S REPORT — GAME FARM ROAD (MILE POST 1.04 TO MILE POST <br />2.54) SPEED LIMIT REDUCTION REQUEST <br />PUBLIC HEARING DATE SEPTEMBER 17, 2019 <br />ACTION REQUESTED CONSIDER REDUCING THE POSTED <br />SPEED FROM 50 MPH TO 35 MPH <br />LEAD STAFF: Mark R. Cook, Public Works Director/County Engineer <br />RECOMMENDATION: <br />Reduce the posted 50 Mile per Hour (MPH) speed limit to 35 MPH. <br />BACKGROUND: <br />Currently the speed limit along Game Farm Road from Wilson Creek Road (MP 1.04) to Naneum <br />Road (MP 2.54) is 50 MPH. A county resident requested the County Engineer evaluate the road <br />segment for sight distance restrictions resulting from numerous vertical curves in the roadway <br />segment. Public Works survey staff conducted a survey of four vertical curves following the site <br />visit by the County Engineer. The results of the survey were presented to Kittitas County <br />Commissioners during Public Works study session of August 26, 2019. <br />DISCUSSION: <br />County Roads are typically designed to national standards relative to horizontal and vertical <br />curve requirements. Vertical curves typically are designed such that a car can safely stop in a <br />distance defined by the posted speed limit. The four vertical curves surveyed on Game Farm <br />Road do not meet national minimum standards for safe sight stopping distance at 50 MPH. <br />Three of the curves meet the requirements for 35 MPH while a fourth requires a slower speed. <br />Public Works proposes lowering the speed limit on Game Farm Road (MP 1.04 to MP 2.54) to <br />meet minimum national standards for safe sight stopping distance. The fourth curve will be <br />signed as an advisory 25 MPH. These changes are anticipated to increase safety for area <br />residents and the traveling public. <br />FISCAL IMPACTS: <br />The cost of re -posting Game Farm Road to 35 MPH is expected not to exceed $3,000.00. <br />ATTACHMENTS: <br />EXHIBIT 1: Game Farm Road Survey Results <br />Page 1 of 2 <br />PUBLIC WORKS BOARD OF COUNTY CONMUSSIONERS ENGINEER'S REPORT <br />
