CASE # (, d� PUBLIC HEARING AND LEVY OF SPECIAL ASSESSMENTS FOR THE 2010 STREET MAINTENANCE PROGRAM By: Steven J Jankowski, Assistant City Engineer Background: The 2010 Street Maintenance Program consists of six individual projects addressing the maintenance needs of 14.24 miles of streets. Three projects involve crack fill /sealcoat covering 11.44 miles of roadway. One of the sealcoating projects is being special assessed in accordance with the City's Street Maintenance Policy. The crack fill /sealcoat assessments were previously assessed 50% of the project cost, however the assessment on this type of maintenance work is being phased out, with 2013 scheduled as the last year for which assessments will be utilized for this type of work. This year the assessment for sealcoat/crack fill work is 29% of the project cost. The remaining two projects are the first seals for these streets and are being financed through developer escrows and city Municipal State Aid (MSA) funds. Three projects involve a 1 /2 inch bituminous overlay covering 2.80 miles of roadway. Two of the projects have been completed and the third project, a bituminous overlay of Waco Street and 142 " Avenue in the River Bend subdivision, is scheduled to be completed prior to the public hearing. The final costs have been estimated at the time of this writing. It is City policy to assess 50% of the project cost to the benefited property owners for overlay projects. Final assessments are determined by dividing the total assessable amount equally between the number of benefitted properties within the project area. One overlay project, Project 10 -06, has only 12 assessable properties and is being assessed the average assessment of the other 2010 bituminous overlay project; consistent with assessment policy # 7. Below is a summary of the assessments proposed on each project along with a comparison to the estimated costs reported to property owners prior to the March 9, 2010 public hearing: For Improvement Project 10 -04 the actual costs were higher than those estimated in the feasibility primarily because the amount of concrete curb replacement substantially exceeded anticipated quantities. This assessment was limited to 110% of the original estimate. This project also affected the average overlay cost associated with the Final Feas Study % of Assessment Est.
