The total cost of street, storm sewer, watermam, and sanitary sewer improvements was estimated to be$394,900. Existing Conditions There is currently no roadway that connects Veterans Drive and Sunwood Drive NW in the proposed project area and no buildings exist on the adjacent sites. At each of the adjacent roadways, there are existing entry points into the site. Based on available aerial mapping, the width was measured to be 36' face-to-face. It was assumed that storm sewer, watermain, and sanitary sewer do not exist within the proposed roadway corridor,but that stubs for these utilities are available at the entry point from Sunwood Drive NW. No subsurface soil information was available for the preparation of this report. A conservative assumption that silty/clayey sands are located onsite was used. Proposed Improvements The proposed street section for Yolite Street was assumed to be a 275-foot long, 36-foot wide (face- to-face) urban street section between Veterans Drive and Sunwood Drive NW. The proposed street section will consist of 1.5 inches of bituminous wearing course, 2 inches of bituminous base course, 8 inches of Class 5 aggregate base, and 12 inches of select granular borrow over an acceptable, compacted subgrade. It was assumed that the future site uses would not generate a significant amount of truck traffic. A geotechnical study was not provided by the City and so it was conservatively assumed that a 12 inch sand section will be added to the City standard detail for an urban street. Concrete curb and gutter will be installed on both sides of the street and will tie into the existing curb and gutter at Veterans Drive and Sunwood Drive NW at each end. A 6-foot wide 6" concrete walk is proposed on both the east and the west side of Yolite Street. Streetscape improvements, in accordance with the Ramsey COR design standards, are proposed for the 6-foot wide boulevards between the proposed curb and concrete walk. These improvements include deciduous trees, two types of lighting units, irrigation systems, and benches for pedestrians. Page 1
