KITTITAS COUNTY <br />DEPARTMENT OF PUBLIC WORKS <br />PUBLIC WORKS — BOARD OF COUNTY COMMISSIONERS <br />STUDY SESSION STAFF REPORT <br />STUDY SESSION DATE: May 8, 2017 <br />TOPIC: Wiehl Road Improvement District <br />ACTION REQUESTED: Informational <br />LEAD STAFF: Mark R. Cook <br />RECOMMENDATION: <br />Direct staff finalize the financial plan for the RID and gather petition signatures <br />supporting RID formulation. <br />BREIFING SUMMARY: <br />• Residents accessing Wiehl Road are preparing a petition to finalize a Road <br />Improvement District <br />• Public Works has completed a design and cost estimate for construction <br />• The community still needs to resolve multiple parcel ownership issues <br />• Public Works needs to resolve a commercial activity using the road <br />• Late comers may require resolution <br />BACKGROUND: <br />Last year, Public Works (PW) pulled community members together discussing the need <br />to improve Wiehl Road. Currently, Wiehl Road is unopened County Right of Way <br />serving approximately 30 households. Some of the homes remain on temporary <br />occupancy permits dating back several years. <br />The proposal affords access to 63 lots of varying size (Exhibit 1). At buildout, the private <br />dead end roadway will serve in excess of 30 lots without a secondary access. Many of <br />the lots predate the revised road standard maximum lot service number of 30. <br />DISCUSSION: <br />PW has evaluated the possibility of constructing a public road within existing right of <br />way. Owing to slope conditions, a public roadway requires significantly more right of <br />way supporting a series of switch backs to achieve the required maximum roadway grade <br />of 12 percent. The cost of the public roadway exceeds $1.3 million. The RID proposes a <br />private roadway built at 15 percent with an asphalt pavement thickness of 0.3 feet <br />(Exhibit 2) Guardrail and retaining walls are also proposed within the RID. <br />During our discussion last week (04-28-2017), three property owners were identified as <br />owning multiple properties within the RID. A fourth property owner was identified as <br />Page I of 4 <br />PUBLIC WORKS BOARD OF COUNTY COMMISSIONERS WORK SESSION STAFF REPORT <br />
