KITTITAS COUNTY <br />DEPARTMENT OF PUBLIC WORKS <br />PUBLIC WORKS — BOARD OF COUNTY COMMISSIONERS <br />STUDY SESSION STAFF REPORT <br />STUDY SESSION DATE: August 26, 2019 <br />TOPIC: Game Farm Road Speed Reduction <br />ACTION REQUESTED: Set a Public Hearing Considering a Speed Reduction for <br />Game Farm Road Mile Post 1.04 to Mile Post 2.54 <br />LEAD STAFF: <br />Mark R. Cook <br />RECOMMENDATION: <br />Set a public hearing considering a speed reduction for Game Farm Road mile post 1.04 <br />(Wilson Creek Road) to mile post 2.54. <br />BRIEFING SUMMARY: <br />• Recently, Public Works (PW) conducted a sight distance study on four vertical curves <br />on Game Farm Road between Wilson Creek Road and Naneum Road <br />• The road segment is currently 50 MPH <br />• The roadway lanes are narrow, approximately ten feet <br />• Sight distance for three curves is met at 35 MPH with a single curve dropping down <br />to 25 MPH <br />• PW suggests reducing the speed to 35 MPH and signing an advisory of 25 MPH at <br />the worse curve <br />BACKGROUND: <br />A moderate sized subdivision is approved and the road network has been taken on system on <br />Game Farm between Wilson Creek Road and Naneum Road. Construction of residential lots <br />has not begun at this time. Once built, the residential traffic on the road segment will likely <br />double in average daily traffic counts. Existing vertical curves do not meet minimum sight <br />distance design standards for 50 MPH. <br />ETI' Curtis has conducted an engineering evaluation of existing vertical curves along Game <br />Farm Road and confirmed the curves do not meet minimum sight distance requirements for <br />50 MPH. One curve does not meet 35 MPH design standards. PW recommends reducing the <br />speed on Game Farm (1.04 to 2.54) to 35 MPH and signing an advisory at 25 MPH for single <br />none compliant curve. <br />FISCAL IMPACTS: <br />Resigning the road segment is expected to cost approximately $2,000. <br />ATTACHMENTS: <br />Exhibit 1: Curve graphic <br />Page 1 of 2 <br />PUBLIC WORKS BOARD OF COUNTY CONMUSSIONERS WORK SESSION STAFF REPORT <br />
