2/9/2011 Pavement Management Plan-2011 Supplement The City of Centerville adopted a Pavement Management Study and Plan dated October 9, 2003. This plan was the basis for improvement projects in 2004 and 2009. This plan identified one additional list of streets that needed reconstruction which is scheduled for 2015. The city currently has 17 miles of paved streets. The city streets are generally 32 feet wide from face of curb to face of curb and have concrete curb and gutter. The City of Centerville's Pavement Management plan consists of four distinct parts—annual crack filing, seal coating, mill and overlay, and total street reconstruction. Crack Fillins� This is done on an annual basis in order to mitigate the damage caused by water penetrating the base of the street through surface cracks in the asphalt. Budget $15,000 included in annual General Fund operations. Seal Coatins� Seal coating is a process of laying down oil and covering it with rock in order to extend the useful life of the road surface. Each section of street is completed approximately every six years. The City plans to seal half the streets at a time resulting in a project every three years. The budget contains $60,000 each year which accumulates in fund balance until the third year when a project is completed. 'I Budget: $60,000 in annual General Fund operations. '� Street Reconstruction There is one major street reconstruction project left within the city to get all of the city streets to substantially the same standard of construction. Areas are shown on the map attached as Exhibit A. They consist of—Area 1: South Robin Lane North Robin Lane West Robin Lane ' Cardinal Drive; Area 2: Peterson Trail, Fox Run, Houle Circle & Ha�eld Road; Area 3: 73rd Street between Mill Road and the portion completed in 2009; Area 4: Center Street east of Dupre along with Sumac and Ivy Courts; Area 5: Mound Trail and LaValle Drive watermain; Area 6: ', Downtown streets (except Centerville Road s of Main and not including streetscapes). Areas 1, 4, 5 and 6 include the cost of city water in the project. It is anticipated that the cost of water would i be paid by the Water Fund in the same manner as 2009 and then collected upon hookup in the form of a connection fee. Area 6 has some sanitary sewer costs that would be paid by the Sewer fund. Cost estimates are contained on the attached Exhibit B. In order to fund this project it is anticipated that the City will issue improvement bonds in the amount of about $3.5 million that are repaid through a combination of tax levies and special assessments as shown on the attached Debt Service and Levy Summary-Exhibit C. The policy of past practice is to assess approximately 25% of street reconstruction. Estimated 2015 Project Cost in 2011 dollars: �4,487,500 Mill and Overlav The newest component to the capital improvement plan is the mill and overlay as maintenance. This is not a complete reconstruction of the street, but rather milling off part or all of the surface and then reapplying the asphalt surface. The first mill and overlay in the plan is proposed for 2020 and is estimated to cost about $1.2 million. If the Council wishes to avoid issuing debt for the project and special assessment for part of the cost, it is recommended that the City begin
