F. 173ra Avenue Existing Conditions This segment of unpaved roadway consist of a 20-foot sand surface for a distance of 1600 feet west o f C SAH 5, just south o f C R 6 3. This roadway exists within 66-foo~ right-of-way and services two farmsteads and another single family residence whose driveway is less than 200 feet off of CSAH 5. The roadway is adequately elevated above farmland which exists on both sides of the roadway, except for the westernmost 100 to 200 feet. The roadway does not end'in a cul- de-sac, but rather turns southward extending into a private driveway: Tlxere appears to be little opportunity to construct a cul-de-sac at the terminus since the adjacent side stope.s r/se 3 to 4 feet above the elevation of_the existing road. Proposed improvement - Alternative A - Gravel Surface The major length of this roadway would only receive four inches of~avel to the existing surface. On the westernmost 150 feet ditches would be established conforming to the cross section illustrated in Figure A. Following construction, an application of calcium chloride for dust control would be applied annually in spring or summer. The road would be regraded approximately monthly betWeen April and October. AtSer five years 2.inches of Class 5 would be added to the surface. Proposed Improvements - Alternative A - Paved Surface Similar improvements to those described in Alternative A above would be made to improve drainage on the far west end of the roadway. The roadway would be surfaced with two inches of Class 5 as illustrated in Figure B..Following construction, a seal coating would be applied after 5 Years.
