AREA B This area was eliminated from the 2009 project based on input from the public who wished to see the overall cost of the project reduced. These streets are being considered for improvements as part of the last remaining unimproved streets from the 2003 study which already have city water main. In the 2009 study, these streets were slated for full reconstruction. However due to the fact that a reconstruction of the road would trigger the need for costly rain gardens or other infiltration features, a more limited scope of improvement is being considered. Area B is proposed to be a part of the project studied under this report. Proposed improvements include: • Full bituminous removal and replacement • Spot repairs of curb and gutter • Limited draintile installation STREET IMPROVEMENTS - FULL BITUMINOUS REMOVAL AND REPLACEMENT Streets in this portion of the project will have the existing gravel section left in place along with the curb and gutter. The new section will consist of draintile, the existing gravel base and new bituminous (see Figure 4). Spot repairs to the curb and gutter as well as to the gravel base could be made as necessary. Draintile could be trenched in along the front edge of each of the curb lines to help maintain the integrity of the subbase. For the most part, curb and gutter in these segments is in good condition and will require only spot repairs. This means that little or no disturbance behind the curb will take place, keeping costs at a minimum. Part of the reason for the deterioration of these streets is often a lack of proper surface drainage. Therefore, the proposed improvements include additional catch basins and storm sewer where it is both needed and reasonably feasible.
