INTRODUCTIO~ A petition dated July 7, 2004 signed by all three of the residents located on the St. Francis Boulevard frontage road so of' 160c" Lane was received at the July 20, 2004 meeting of the Public Works Committee. This petition which is included as Appendix A of this report requested improvement of the existing dirt roadway and consideration of.financial assistance from the City in making improvements. The Public .Works Committee and the City Council responded by providing direction to staff relative to ti-is issue at their July 20, 2004 and August 10~ 2004 meetings, .respectively. The minutes of these meetings addressing this issue is contained in Appendix B of th.is report This report is intended to comply with the City Council direction and will identify the cun'ent conditions and along with the proposed imp.rovements and the associated costs. Finally this report will outline the proposed method of £mancing for each element of the improvements. EXISTING CONDITIOtNS The existing street consists of a graded native sand base roadway with rural roadside ditches on both sides. The roadway is approximate 21 feet wide for a length 700 feet south of' 160th Lane. This segment is terminated with an egg shaped cul de sac Which is approximately 80 feet long and 60 feet wide. This existing roadway does not appear to be centered within the 45 foot right of way that is dedicated for this service road on the plat of the Hall Anderson subdivision. Instead it appears that the east edge of the roadway is located on the east right of way. The northerly two residences fronting on this road are set back 30 feet from the west right of way line, while the southerly residence is set back 40 feet. Three residences are serviced by this road. The north and south properties have a single driveway access, while the middle parcel has two driveways, one for the residence and a second for a detached out building. PROPOSED IMPROVEMENTS This project proposes tO grade the roadway to a width of 32 feet with the additional 1 l feet of width extending westward from the- existing- alignment. This would result in the .existing residences being located between 45 to 55 feet from the edge of the paved roadway. The pavement section shall consist of 4 inches of class 5; two inches of bituminous base course and 1.5 inches of bituminous wear course. The easternmost eight feet of this section shall be striped for use as a trail for pedestrian and non motor/zed traffic. In order to confine the widened roadway to the 45 foot right of way reserved for the city, it will be necessary to install a bituminous b'erm curb along the western edge of the pavement. This will also preserve the landscaped hedgerows of trees and.shrubs, which would otherwise need to be removed to accommodate a ditch section. The vertical grade of the road way shall be approximately the same as the existing, however, this grade may -126-
