INTRODUCTION At the May 20, 2008 Public Works Committee meeting the Committee was presented with a petition signed by 54 persons representing 36 of the 67 properties benefitted by this proposed project, A copy of this petition is included in Appendix A. Andrie Street and 164th Lane had been proposed for a bituminous overlay in 2008 as a part of the annual street maintenance program. The petition requested that Andrie and 164th Lane receive additional improvements primarily concrete curb and gutter and other elements which would bring the street in compliance with Municipal State Aid (MSA) standards, City Council directed the preparation of this feasibility study on June 10, 2008 in response to this petition. The project area and benefitted properties is, illustrated in Figure 1. This report will identify the existing street condition along with the proposed improvements and the associated costs and financing, including the cost to each benefitted property, The reader is referred to the proposed improvement and financing sections of this report for the details concerning these project elements. Finally this report will provide a project timeline. EXISTING CONDITIONS Both Andrie Street and 164th Lane were constructed in 1985 as a 31 feet wide roadway with a four inch class 5 base and a two inch bituminous wear course which was standard construction requirements at that time. The roadway has a bituminous berm curb and is serviced with storm sewer and a number of catchbasins which discharge to adjacent low areas. These areas are encumbered with drainage and utility easements to allow. for this purpose. The road has received periodic maintenance including cracksealing and sealcoating operations which were performed most recently in 1999, The road surface is exhibiting deficiencies consistent with its age which include alligator cracking in low lying and flat areas, and particularly severe raveling along the bituminous curb line. This raveling has probably been aggravated by the intensive use of irrigation systems along the roadway. At several locations the drainage must travel overland for a distance in excess of 700 feet to reach a storm sewer. Many of the catch basin structures are constructed of concrete block which have failed or are deteriorating, PROPOSED IMPROVEMENTS The existing two inch mat of bituminous along with the bituminous curb and gutter shall be removed and shall be reclaimed as base material at a minimum thickness of four inches: A 32 foot wide bituminous pavement is to be constructed in the center of the 66 foot right of way. The pavement section will consist of a four to six inch class 5/reclaimed bituminous base, two inches of bituminous base course, and 1,5 inches bituminous wear course which constitutes a 10 ton street design in Ramsey's sandy Page 2
