Item # 5.4. MEMORANDUM TO: Mayor and City Council FROM: John Anderson, P.E. DATE: April 12, 2010 SUBJECT: Main Street Pavement Rehabilitation Background The City Council discussed the need for pavement rehabilitation on Main Street from Lowell Avenue to the Bridge in 2009. This item was included in the Capital Improvement Plan for 2010. The City Council has expressed an interest in assessing a portion of the cost of this project to the benefiting properties. Staff feels that it is worth considering expanding the scope to include the section of Main Street from the Bridge to Orono Road. Proposed Improvement The proposed pavement rehabilitation process proposed for this roadway is Full Depth Reclamation. This is the same process as was done in 2009 in the Morton /Norfolk neighborhood. It involves grinding the existing pavement and blending it with the gravel below, shaping and placing two, two- inch layers of bituminous pavement. Plans for this work have been prepared as part of the stimulus funding application submitted in 2009. The standard fox pedestrian ramps has changed since the reconstruction in 1988 and possible upgrades to these installations may be required to be included in this project. Assessments The areas that this section of Main Street is in have been assessed for various past projects that include the following, 1988 Main Street Reconstruction, 2003 Reconstruction, 2005 Reconstruction, 2008 Overlay, 2009 Full Depth Reclamation. It has been assumed that properties previously assessed fox all projects, except the 1988 Main Street Reconstruction, will not be assessed for the 2010 project. Staff is suggesting that the assessment rate for 2010 be set based on bituminous overlay projects in the past. Schedule As the project is proposed to be assessed, the schedule fox the project needs to accommodate the public hearings and notices required by MN Chapter 429. A project schedule has been laid out that begins with the Ciry Council considering ordering a Feasibility Study at the Apri119, 2010 Ciry Council meeting. T'he construction is targeted to begin after the Sherburne County Fair Parade in mid July on Main Street and conclude before school opens in September. I have prepared a presentation on these issues and will be in attendance at the Apri112, 2010 Ciry Council Workshop to present this material and answer questions.
