CASE #2 CONSIDER PROCESS FOR STREETS SCHEDULED FOR RECONSTRUCTION IN 2006 CIP By: Steven Jankowski, City Engineer Background: The Capital Improvement Program has two street reconstruction projects scheduled for implementation in 2006; Dysprosium Street from CR 116 to 143ra Avenue, and Garnet Street and 168th Avenue in the Now and Then Estates subdivision. Both these projects should receive careful consideration pr/or to proceeding with implementation. In the case of the Now and Then Estates, these streets were constructed in 1988 with a mad structure that was typical for the City's predominant sandy soils. This area however contains clay soils and the roadway exhibited signs of pavement failure shortly after construction. As a consequence the City has patched these streets on an as needed basis and has never performed routine maintenance knowing that reconstruction would ultimately be required. Consequently these residents have never been assessed for the repair and maintenance that other City residents have incurred. On the other hand these residents have endured the generally poor condition of these roads over this period. One element of this project would be to determine what portion of the cost of the reconstruction shall be assessed to the residents. A second issue associated with this project relates to the close proximity that sanitary sewer and water will be to this subdivision by the end of 2006. It would seem inappropriate to reconstruct these roadways without the installatibn of urban services given the proximity the proposed Brookfield development and the indicated desire by many of the residents within Now and Then Estates to subdivide their properties. The installation of urban utilities in this subdivision in turn would require consensus on where future streets are to be installed. Finally, the activity associated with the construction of the Brookfield development is likely to have an impact on the streets in Now and Then Estates despite best efforts to limit traffic through this subdivision. It may result in a better product if this reconstruction was implemented after a substantial portion of the Brookfield Development has taken place. Dysprosium Street was constructed between 1985 and 1987 and has received periodic preventative maintenance, but the pavement condition has deteriorated to a point were reconstruction of the pavement is recommended. This is particularly true because of additional design considerations such as adding sidewalks and incorporating traffic calming and an enhanced streetscape. The Dysprosium Street project has a similar issue relating to the level of contribution from the benefiting property owners. However, recent discussions of revising the configuration of TH 47 also has an impact upon this project.
