I ~ most severe in the western end of the street, again, indicating major structural distress within the pavement section. Bussard Court has a Pavement Rating of 30 of a possible 100. Storm drainage flows toward the intersection of Bussard and Snelling Avenue where it is collected by catch basins and routed through storm sewer piping. A catch basin is also I located within the cuI de sac on the west end of the street. This drains to the west into Lake Johanna. It would be appropriate to place additional catch basins at the opening of the cui de sac and change the grades along Bussard Court to improve the storm drainage system, making I it an adequate system to remove storm runoff from the subgrade, streets and tributary properties. I AET advanced three soil borings within Bussard Court, indicating two-inches of bituminous pavement overlying four to ten-inches of non-crushed gravel base. The boring locations are presented on Exhibit 3 and the report is presented in Appendix A. The subgrade soils are I mostly sandy lean clay fill with some clayey sand and lean clay. The fill placed in the cuI de sac was particularly soft and moist, again indicating the need for subgrade drainage if reconstruction is the selected option of rehabilitation. I Dunlan Street I Dunlap Street extends from Ingerson Road north approximately 1,100 feet to a dead end north of Cannon Avenue. The roadway is approximately 32-feet in width and has deteriorated II bituminous curbing within a 6O-foot wide right-of-way. The area in which the roadway is located is again zoned R-l, single family residential. Due to the zoning and associated traffic characteristics of Dunlap Street, the street should be constructed to meet the 32-foot wide, 7- I ton design standard for an urban residential street. There are no apparent maintenance requirements associated with the watermain. The sewer is scheduled for televising prior to the construction taking place to determine whether any maintenance or repairs are required. I The existing bituminous surface along Dunlap Street is level and the distress is less severe than the pavement on Amble Drive and Bussard Court. There is alligator cracking and some I surface scaling present along the entire length of Dunlap Street. Additional information regarding the pavement conditions is presented in AET's report. Again, Dunlap Street is one of three streets most in need of rehabilitation in the City with a Pavement Rating of 33 out of I a possible 100 points. . Storm drainage flows toward Tiller Lane which was reconstructed in 1991 with subgrade I drainage and storm sewer improvements. The street grades along Dunlap Street are currently inadequate to remove the runoff from the street and tributary areas just north of Ingerson Road. Additional catch basins and storm sewer piping may be necessary to better I accommodate the storm drainage in the vicinity of this intersection. AET advanced three soil borings along the length of Dunlap Street indicating bituminous I {' 7 I
