Andrie Street and 164k~' Lane had been proposed for a bituminous overlay in 200$ as a part ofhhe annual street maintenance program. The petition requested that Andrie and 164 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 casts 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. E~isTINC cal'~z~I~rlc-Ns Both Andrie Street and 164" Lane were constructed in 1985 as a 3l 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 stone sewer and a number of catch.basins 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. PR~?PQSELI IIY~PR~VEMENTS The existing two inch mat of bituminous along with the bituminous curb and gutter shall be removed anal shall be reclaimed as basematerial at a minimum thickness of foux 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 -112 - ,~.. • .,~.-._..-~.~.. .~.,-.,....~.,~..._W._. ..~._„ -Page 2 •..._..~.,~.~. ,.-,.~.•-..~,~.,,~..~._.. .~_•
