PROPOSED CONSTRUCTION General Comments City staff has worked closely with the neighborhood to develop preliminary plans that meet the needs of both the neighborhood and the City at large. This is a Municipal State Aid (MSA) roadway and state aid funds will be used to pay for a portion of the costs; the roadway must be constructed to meet minimum MSA standards. The preliminary design, as presented in this report, meets all applicable standards. The proposed street width and parking is discussed in the following sections of the report. The roadway will be constructed with a 10 -ton structural design, bituminous pavement, and concrete curb and gutter north of Roselawn Ave. The new pavement section for the road will be a reclaimed aggregate base with 4 inches of new bituminous pavement. This recommended improvement will meet the City's and State Aid's minimum standard for a 10 -ton design roadway. The concrete curb and gutter will be B618 barrier curb design and will be constructed on both sides of the roadway north of Roselawn Ave. There is also a small stretch of bituminous curb south of Roselawn and this will also be replaced with concrete curb and gutter. Existing street grades will be maintained in their current condition. The final design may take advantage of some minor variations of a few inches in order to provide a better transition from roadway to private driveways where possible. The existing manholes and other structures will be adjusted as necessary as part of this project. The sanitary sewer mains were lined in 2014. In addition, property owners with roots in their sanitary sewer services will be given an opportunity to replace their services at their expense. Staff is not recommending replacement of the watermain due to the low historical occurrence of watermain breaks in this area. There may be some maintenance work on sanitary and water main structures such as manholes, valves and hydrants as a part of this project that will be funded by the appropriate utility fund. If unsuitable material is encountered beneath the existing pavement during construction, it will be removed and replaced with suitable backfill material. Any sod that is damaged as a result of the project will be replaced. As staff is recommending maintaining the existing profile/grade of the roadway, we do not anticipate impacts to in place driveways. If staff is able to make some adjustments that favor the driveway grades and/or the transition from roadway to driveway, driveway approaches will be removed approximately between the existing pavement and the property line. The removed driveway will be replaced with similar material- bituminous or concrete. Project P -ST -SW -15-02 Feasibility Report Victoria Street Reconstruction ou
