Valentine Court is proposed to be 24 feet wide, and Valentine Crest. Road is proposed to be 28 feet wide, which matches the existing conditions. It isprop osed to use B618 curb and gutter on the project. It provides a traffic barrier, eases snow plowing, and provides increased drainage capacity. From the survey, the residents did not have a strong preference on the type of curb proposed. There is a vegetated island at the end of Valentine Court that is hard for large vehicles and snow plows to workaround. The City's Public Works Department has suggested that it be modified to accommodate truck turning movements. In addition, it is being con sidered as an area for stormwater management. It is proposed to improve this area with this project. Driveways will be matched in kind with either bituminous or concrete. Concrete aprons will be installed at gravel driveways and as needed to control drainage. Boulevard areas will be restored with 6 inches of topsoil and sod. Tree removal will only be as necessary to replace utilities.. Tree replacement will be considered along with clear zone set backs. The clear zone is for safety; it provides an area behind the curb without obstacles. 4.1.2 Janet Court, Katie Lane, and Katie Court The existing bituminous pavement is in need of reinforcement. It is recommended that the streets be milled to a depth of 2 inches and fortified with a 2-inch overlay. The curb and utter will only be replaced where sunken or damaged, and the roadway alignment g Y p .. will not change. Necessary corrections to the subgrade will be made in areas exhibiting g more severe signs of distress prior to paving the overlay. PCI ratings for these roadways range from marginal to adequate. While improvements to the adequate sections may seem premature, when combined with the marginal segments, it will likely be more cost-effective to make improvements at this time. If improvements p , are ost onedthe project costs would increase due to increased deterioration, as well as p p construction cost increases. Also, in keeping with the neighborhood approach, comp leting the neighborhood improvements at the. same time will minimize inconveniences to the residents. 4.2 Storm Sewer 4.2.1 Valentine Avenue, Valentine Court, and Valentine Crest Road Storm sewer improvements include replacing the existing concrete pipe and manholes as needed. Catch basins will be added to improve drainage in problem areas identified by City staff/residents and in low points. To meet State Aid requirements a drainage report for Valentine Avenue will be completed ensuringsufficient drainage of the roadway and right of way to Mn/DOT standards. The drainage report includes a project -specific catch basin spacing design, pipe i capacity design, and a HydroCAD anaylsis.
