2023 Docket Enabling Ordinance December 19, 2023 <br />Page 66 <br /> <br /> <br />B. Private Roads. A Private road is defined as any access serving five or more lots <br />(including residential, commercial, industrial, or agricultural use), residences, or multi- <br />family units that is privately owned and maintained. <br /> Private roads are classified as urban and rural just as the public county road system. <br />They must meet the Kittitas County private road minimum design standards as <br />identified in these standards. Benefited property owners are required to perform their <br />own maintenance and repair work. Operation and maintenance agreements to provide <br />for this work on both the road network and the stormwater system are required. Short <br />plats proposed on properties to which the access is over private roads that do not meet <br />the standards in this section shall be recommended for denial unless upgraded to the <br />current standard. <br />1. Private Rural Road: Like rural county roads, private rural roads serve rural lots. <br />They typically lack urban elements such as curb and gutter, sidewalks, and <br />underground storm drainage systems, but may include other pedestrian and <br />bicycle facilities. Storm drainage systems for rural roads typically utilize ditches <br />and culverts. See KC Standard Plan 8. <br />12.03.040 Terrain Classification. <br />For the purposes of these standards, existing and proposed roadways in Kittitas County are <br />divided into terrain classifications based on ratios of roadway profile slopes present for a given <br />roadway segment. Profile slopes shall not exceed 10% maximum in any classification. Terrain <br />classifications shall be as follows: <br />A. FLAT –At least 75% of the existing terrain along the roadway corridor has a profile slope <br />that is less than or equal to 5%. The remaining 25% of the existing terrain along the <br />roadway corridor may be steeper than 5%. <br />B. ROLLING TERRAIN – Moderate changes in elevation with respect to the roadway <br />corridor, and occasional steep slopes offer some restriction to normal horizontal and <br />vertical roadway alignment. At least 75% of the existing terrain along the roadway <br />corridor has profile slopes that are greater than 5% and less than or equal to 10%. The <br />remaining 25% of the existing terrain along the roadway corridor may be classified as <br />either flat or rolling. <br />C. MOUNTAINOUS TERRAIN - Longitudinal and transverse changes in the elevation with <br />respect to the road or street are abrupt, and frequent cut and fill is needed to obtain
