Title: 12 - Roads, Parks and Waterways

Chapter: 04 - Urban and Rural Public Road Standards

Section: 85 - Existing roads

A.   If a portion, or all, of a parcel as shown on the latest county equalized assessment roll abuts an existing county road and such parcel is subject to this chapter, the applicant shall make an irrevocable offer of dedication of sufficient right-of-way to enable the abutting section of road to be constructed to the standards set forth herein. The applicant shall improve the following portions of the abutting road to comply with this chapter subject to the following:

1.  If the parcel abuts both sides of a county road, the im­provements, as determined under Subsection (A)(3) of this section, shall be made to the full width of the road.

2.  If the parcel abuts one side only of a county road, the improvements, as determined under Subsection (A)(3) of this section, shall be made to the abutting one-half width of the road except as hereinafter provided.

3.  Road improvements described in Subsections (A)(1) and (A)(2) of this section shall be performed by either widen­ing the existing road or reconstructing the existing road as determined below:

Case I: If the cross slope of the existing traffic lane is equal to or more than 1.5 percent and equal to or less than 3.5 percent and the existing longitudinal grade of the road meets drainage and safety standards as approved by the county engineer, then: construct a new pavement section between the edge of the existing street and the lip of the new gutter (or hinge point, if rural). The new pavement section shall follow the existing longitudinal grade of the road and match a gutter (urban) or shoulder (rural) that has been designed with a uniform longitudinal slope. The design goal shall be to provide a cross slope for the pave­ment section of 2.5 percent slope if possible.

Case II: If the cross slope of the existing traffic lane is less than 1.5 percent or more than 3.5 percent and the existing longitudinal grade of the road meets drainage and safety standards as approved by the county engineer, then: recon­struct the entire half width of the road from the centerline to the lip of the new gutter (or hinge point, if rural) and provide a cross slope of 2.5 percent.

Case III: If the cross slope of both lanes (entire road width) of the existing pavement is either less than 1.5 percent or more than 3.5 percent and/or the developer or county engineer desires to change the longitudinal grade of the road, then: both lanes of the road shall be recon­structed with the proper cross slope and grade.

B.   Road improvements for projects which front onto existing roads shall, at a minimum, extend along the frontage of the parcel being developed.

C.   If a portion or all of an existing single-family residentially zoned parcel, within an urban area, as shown on the latest county equalized assessment roll, abuts an existing county road or city street and such parcel is subject to this chapter, see Section 12.04.111. (Ord. 97-17 (part), 1997.)
