Jankowski, City Engineer CASE Background: At tonight's meeting, public hearings will be held on Improvement Projects #98-01 through 98- 12, which will comprise the 1998 Annual Street Maintenance Program. A copy of the feasibility study was originally presented at the February 10, 1998 Council meeting, and has been transmitted to the Council under separate cover from tonight's agenda. The City performed its first sealcoating work in 1981, and has had an annual program for addressing the preventative maintenance needs of its bituminous streets since that time. A copy of the City's pavement history and sealcoating program is illustrated in the attached table. Through the 1990 program, it was the City's policy to assess the total cost of this program. Beginning in 1991, the City changed policy, and now assesses 50 percent of the total project cost. The City has a considerable investment in the nearly 132 miles of paved roadway for which it is responsible. It is estimated that the replacement costs of the bituminous and road base approaches $10 million. In order to preserve the investment in its bituminous pavements, the City has a goal of applying a sealcoat to new pavements, including overlays after a five-year period and to reseal an overlay as needed at seven-year succeeding intervals. This year's program consists of twelve individual projects, covering 12.54 miles, which will receive sealcoating preceded by crack filling of the cracks wider than 1/4 inch. In addition, 9.01 miles of street in five projects, #98-08 through #98-12, will receive 1-1/2 inch bituminous overlays. Projects have been aggregated by properties having similar lot sizes and pavement conditions, usually by subdivision. Total project costs are then calculated for each project and divided equally among the number of benefited properties. Project #98-01 is somewhat unique in that it incorporates 29 indi:vidu~l subdivisions, all but two of which have sewer and water. These subdivisions have many common characteristics including similar lot areas and frontages. All are new pavement ranging from three to six years old, and all have had developer escrows contributed toward the first sealcoating. For these reasons, they have been aggregated into a single project. Project #98-12 proposes a bituminous overlay project on 5.5 miles of Minnesota State Aid (MSA) streets which include 167th Avenue from T.H. #47 to C.S.A.H. #5, 153rd Avenue from C.S.A.H. #5 to Roanoke Street, and Variolite Street and 155th Avenue west of County Road #56. The total project cost on these roadways is estimated to be $353,063 and is anticipated to be funded through the City's MSA construction account which currently has a balance of $685,000. Our past practice has been to assess properties fronting on MSA roads which have no other frontage on local streets, an amount equal to the average assessment which other properties receiving a similar benefit had been assessed in that year's program. This was done with 153rd/155th Avenue in the 1995 program and with 167th Avenue in the 1992 program.
