INTRODUCTION A petition for bituminous paving was received and certified to the City Council on May 9, 1995, by three properties fronting on the segment of Bison Street between County Road #63 and 171st Avenue. The purpose of this study is to determine the feasibility associated with providing this segment of Bison Street with bituminous pavement. This study will describe the extent of the improvements proposed and identify the project costs and financing obligations. The final section of this report also describes the process the City will employ for this improvement project and provides a projected schedule for key milestones. EXISTING CONDITION~ The present street consists of a rural street section with a gravel and sand surface approximately 21-26 feet in width. The depth of the gravel surface was found to be between zero to three inches. The history of the road right-of-way is somewhat involved. In 1966, the roadway was intended to run a/ong the common border of two properties which occupied the entire north/south distance between C.R. 4/63 and the half section line of Section 9. At that time, each property owner conveyed an easement to the other for access purposes from C.R. #63 to the half section line of Section 9. As parcels were created from these original two, the City began maintaining the existing roadway. Since no formal deed was given to the City, its right-of-way claim is based upon State Statute 160.05(1) which deems streets to be public after six years of maintenance. The City thus has a claim of two rods (or 33 feet) from the centerline of actual use. Nonetheless, both Anderson Estates and Dellwood Hills subdivisions have subsequently dedicated 33 feet of fight-of-way along the boundary between the original two properties which was the original intended location of the road. In addition, the City entered into a stipulation in June 1982 with Leonard and Lorraine Hinton, the property owners at that time, of parcels five and six, to place the roadway in its originally intended location when it became paved. The actual location of the roadway lies as much as 25 feet outside the intended right-of-way at County Road #63 and returns within the intended right-of-way by the time it reaches the intersection with 171st Avenue. PROPOSED IMPROVEMENTS It is proposed to regrade the street to return the roadway to the center of its intended right-of-way north of 171st Avenue. It is proposed to provide a 24 foot wide bituminous roadway consisting of two-inch bituminous wear course placed on top of a four-inch Class 5 base course. The road section shall have a two-foot gravel shoulder and a two foot deep drainage ditch on each side. Culverts will be placed beneath two driveways and a third culvert will be placed across Bison Street at the intersection with 171st Avenue. While this does not meet the suburban standard of a 30 foot roadway with a bituminous curb, it does provide a minimum cost solution to paving this street and it is consistent with the road section in adjacent Golden Eagle Estates. It also eliminates the need for obtaining a drainage easement which would be required if the drainage were to be concentrated by curbline and discharged at specific locations. Following paving of the roadway, disturbed areas will be restored by fertilizing, seeding and mulching available salvaged topsoil. ESTIMATED PROJECT COSTS The estimated construction costs for the project is presented in Table I and includes detailed construction costs and overhead costs. Overhead costs include, but are not limited to, engineering, construction staking, inspection, fiscal, legal, administrative and contingencies. Overhead costs for the project are estimated based upon percentages of construction cost. These percentages are estimated as follows: I I I I I I I I I I I I I I ! I I I
