I I Alternate No.1 Streets , Alternate No. 1 consists of upgrading streets within Zone 1 of the City's pavement management program, as well as all necessary seal coating. Zone 1 includes the area generally northeast of I Highway 10 and west of Lexington Avenue. The proposed work involves the reconstruction of Colleen Avenue, Colleen Circle, Femwood Avenue, and James Avenue; and the bituminous overlayment of various surrounding streets as shown in Exhibit 1. I Colleen Avenue runs from McClung Drive to Hamline Avenue, while Colleen Circle and James Avenue both branch off of Colleen Avenue. Colleen Avenue and Colleen Circle have PCI ratings I of 58 and 59 respectively, indicating that bituminous overlay is no longer a cost-effective option for rehabilitation. The streets consist of bituminous surface in fair condition, with extensive areas of light and moderate severity cracking. Colleen Avenue is 2,400 feet long and 33 feet wide. I Colleen Circle is 205 feet long and 33 feet wide with an 88-foot diameter cul-de-sac. Both streets have existing D418 surmountable concrete curb and gutter. I James Avenue has a PCI of 37, indicating structural failure. The street has extensive alligator cracking and patch areas. It is 625 feet long and 30 feet wide. It has D418 surmountable curb I and gutter from Colleen Avenue to 137 feet south of Colleen Avenue and a bituminous berm through the remainder of the segment. An existing storm sewer system collects runoff near Indian Oaks Court and directs it to the wetland/pond located east of James Avenue. -. It is proposed to reconstruct all of the streets (with the exception of Fernwood Avenue) to the City of Arden Hills standard street width of 32 feet, as measured from curb face to curb face . Existing I bituminous and surmountable curb would be replaced with B618 concrete curb and gutter. Where necessary, the streets would be subcut and select granular borrow and draintiIe would be installed, as required by subsurface soil conditions. The storm sewer and other utilities would be upgraded I as needed, based upon Public Works input and information obtained from the follow-up report. I The costs associated with Alternate NO.1 are included in the Project Costs portion of this report. I Alternate No.2 Streets Alternate No.2 focuses on improving streets near the intersection of Snelling Avenue and County I Road E, in addition to the proposed seal coating and the reconstruction of Femwood Avenue. This intersection is located near the borders of Zones 3, 4, and 5 of the City's pavement management program. The streets to be reconstructed are Oak Avenue, Pascal Avenue, and a I portion of McCracken Lane. At the same time, several nearby streets would receive bituminous overlay improvements. Streets proposed for improvement under this alternate are presented on Exhibit 2. I Oak Avenue is a dead-end street that branches north from County Road E to the west of Snelling f' Avenue. It is 1,758 feet long and 26 feet in width. The bituminous surface is in poor condition, receiving a PCI of 41. The street has extensive areas of patching and alligator cracking, indicating an unstable subgrade and potential subgrade drainage problems. The street has a I shallow bituminous berm and an existing storm sewer system. Oak Avenue has steep side slopes FEAS-520.068 -5- 520-068-10
