Storm Drainage System Existing neighborhood drainage patterns are as shown in Appendix A. The total drainage area under analysis as part of this feasibility study is 30 acres. All street and private property drainage within this area drains directly into Johanna Marsh, which is a wetland complex and City park property adjacent to the neighborhood that carries drainage from Lake Josephine to Lake Johanna. Most street drainage is overland with minimal storm sewer conveyance. Generally, drainage is channeled along the edges of the streets and relies on the boulevard edges to keep the drainage impounded. Approximately 96% of the overall neighborhood drainage area drains overland to Ridgewood Lane at its intersections with Edgewater Street and Glenhill Road. Catch basins and culverts located at or near these intersections capture overland flows, and channel the flows via culverts and ditches to the Johanna Marsh wetland. The remaining area drains to the wetland overland via the MnDOT Highway 51 ditch. All flows discharge to the wetland untreated, with no formal opportunities for sediment, oil, debris capture. Existing storm sewer conveyances are generally in poor condition and have reached the end of their useful life. Existing drainage conveyances are insufficient for capturing excessive overland street flows causing boulevard erosion, excessive pavement deterioration and icing hazards. Upgrades to the existing neighborhood drainage system are essential for properly managing storm drainage from the roadway and provide treatment prior to discharge into Johanna Marsh. The recommended storm drainage system improvements are discussed later in this report. PROPOSED STREET IMPROVEMENTS Due to the existing conditions of the roadways as previously outlined and as shown in the soil borings, City staff is providing two alternatives to be considered for rehabilitation of the roadways. Alternative 1 involves full reconstruction of the street section and adding concrete curb and gutter. Alternative 2 consists of reclaiming the existing bituminous surface and constructing a new pavement on the reclaimed base. Alternative 1 - Reconstruction In 2008, the City of Roseville reconstructed Asbury Avenue and Ridgewood Road up to the City limits to a street width of 28 feet (face of curb to face of curb). A surmountable curb, style 5518, was constructed on the Roseville project. This was the result of a discussion with both Roseville and Arden Hills' residents at a neighborhood meeting about continuity of the street once both cities completed their street improvements. The sections of Asbury Avenue and Ridgewood Road from the municipal border to Glenhill Road within the City limits of Arden Hills were considered to be included in the 2008 Roseville project, but it was decided to delay this work until the streets in the entire neighborhood in Arden Hills could be rehabilitated. To maintain continuity with the already reconstructed street in Roseville, it is proposed to reconstruct Asbury Avenue and Ridgewood Road to a 28 foot width (face to face). Due to the low volume of traffic in the area, it is proposed to narrow Glenhill Road from a 30 foot width to a 28 foot (face to face) width from Asbury to Ridgewood. Since Glenhill Road is 5
