CASE # CONSIDER ESTABLISHING AN ASSESSMENT POLICY FOR MSA STREET CONSTRUCTION PROJECTS By: Steven Jnnkowski, City Engineer Background: At its May 20,2008 meeting the Public Works Committee considered improvements to Andrie . Street and 164th Lane which are eligible for Mlmicipal State Aid (MSA) funding. The adequacy ofMSA funds for the City's entire system was questioned. It was suggested that any policy adopted must be affordable and sustainable as it would need to be applied to the entire MSA system. The,purpose of this case is to present an overview of the City's MSA system future needs and to solicit direction toward an assessment policy. To assist the Committee in assessing future MSA system needs the City's current designated system has been divided into attached Tablesl through 4. A description of needs anticipated within the next ten years for each group is as follows: . Table 1 includes 7.15 miles ofMSA streets which are similar to Andrie Street and 164th Lane in that they were constructed between 20 and 32 years ago as residential streets l;l11d were later added to the MSA system. Most of these segments function as main collector streets for a neighborhood or commercial area. Assuming that 50% to 100 % of these streets would be reconstructed with concrete curb and gutter; new surfacing; and trail or sidewalk within the next lO years ata cost of $700,000 per mile, the needs for this segment of the system would range between $2.5 million and $5.0 miUion. . Table 2 includ.es 8.46 miles ofMSA streets which are over 20 years old. Most of these streets function as main collector streets throughout the City. Assuming that 50% to 100% of these segments would need to be reconstructed and include trail within the next 10 years at a cost of 1,000,000 per mile, the total needs for this segment of the system would be between $4.3 million and $8.6 million. . Table 3 contains 11.76 mile of other existing MSA streets which are newer than 20 years. Assuming that within the next ten years those segments older than 10 years (5.5 miles) will require a bituminous overlay at a cost of $200,000 per mile, the total needs for this segment of the system would be $1.1miUion. . . Table 4 includes 8.07 miles of nonexistent MSA street. These are future routes that have been designated but have not been constructed. Assuming that 20% to 50% of these routes would be constnlcted within the next ten years at a cost of$1,000,OOO per mile, the total needs for this segment of the /System would be between $1.6 million and $4.0 mUlion. Under the scenarios presented above the total ten year cost would range between $9.5 and $18.7 million. These costs do not include right of way and easement acquisition. An analysis ofMSA revenues that might be expected over the next ten years rollows. The current annual MSA allocation is $880,730, and with the recent gas tax increase the revenues had been projected to be approximately $1,000,000. However this projection was based upon the -23-
