Howard R. Green Company Project No. 822530-0030 Feasibility Study Yankton Street Road Improvements Elk River, MN I. Introduction At the October 27, 2003, regularly scheduled City Council meeting, Mark Olson of 18778 Yankton Street and Diane Thiesen of 18741 Yankton Street appeared at open mike to request that the City widen Yankton Street from Trunk Highway (TH) 10 to where it dead ends, in front of his property at 18784 Yankton Street. In response to Mr. Olson and Ms. Thiesen's request, the City Council authorized Howard R. Green Company to prepare this report to determine the feasibility of widening and reconstructing Yankton Street. Exhibit I shows the project location. II. Scope III. The purpose of this study is to examine the feasibility of widening and reconstructing approximately 1,450-feet of Yankton Street from TH 10 to a proposed cul-de-sac in front of 18748 YanktgmStreet. This report will include information on the existing conditions of th¢~,et, proposed improvements, estimated costs, and proposed assess~'~s t'~. e benefited properties using the City's Assessment Manual and past p~ as a guide. Existing Conditions ~ Presently Yankton Street is ~~f(~t dead end, rural section, gravel surfaced road with an average wi~- ~roximately 17 feet. It appears, based on the preliminary survey, that4~i~s'~f the road are located outside of the established right-of-way. ~rnents of the right-of-way are 66 feet wide, 20 feet wide and 40 feet wide as d~dicated in the Alderwood Plat and the Sixth Plat of Camp Cozy. There are no public utilities along the street. Homes in the area are served by private wells and septic systems. Storm Drainage System There is a ditch on the west side of the road that conveys storm water to two culverts (see Exhibit 2). One culvert outlets directly into the Elk River, and the other outlets into the front yard of 18741 Yankton Street, where storm runoff flows over land to the Elk River. IV. Proposed Improvements A. Street Improvements Yankton Street is proposed to be reconstructed to a 24-foot wide bituminous surfaced urban section with bituminous berm. A 24-foot section would not meet the City's minimum standard width of 32 feet. This report attempts to balance the impacts that widening the road and regrading the ditch would have on the environment by providing a road that two vehicles can easily pass each other on. A cul-de-sac would be constructed on the north end of the street. The proposed typical street section would be in accordance with the City standards and would consist of 1-1/2 inches of bituminous wear, 2 inches of
