A 2 foot shoulder on the west side <br /> <br />B.3³®±¬ 7 ³¤± <br /> <br />Concrete curb and gutter will be used to replace all existing bituminous curb and will also be <br />installed in areas north of Roselawn Ave that does not currently have curb. Existing storm water <br />catch basins and other infrastructure will be replaced with new castings to bring them up to City <br />standards and also to work with the new concrete curb and gutter. Additional catch basins will <br />be installed where needed. The boulevards and yards will be graded to drain to the street, <br />where possible. Where this is not possible, catch basins will be extended into areas to capture <br />water. <br />This road is located within the Capital Region Watershed District (CRWD). CRWD requires that <br />this project provide volume control and treatment for the storm water runoff. This can be <br />accomplished through a variety of potential Best Management Practices (BMPs) for stormwater <br />management. <br />City staff is recommending the installation of several hundred feet of perforated pipe along the <br />east-west portion of Victoria Street that will allow rate control, provide some infiltration and also <br />address some drainage concerns in the area. The outlet to this new system is proposed to drain <br />into the very southeast corner of Pioneer Park. A pretreatment cell will be installed at this outlet <br />to provide treatment of the stormwater before discharging into the existing wetland in this area. <br />A raingarden is also proposed in the northwest corner of Larpenteur Ave and Victoria St to <br />provide infiltration, rate control and treatment of stormwater before draining into the <br />Larpenteur Ave stormwater system. <br />%±®²¨®­ #®­³±®« <br />As part of the project plans and specifications, staff is required to prepare a storm water <br />pollution prevention plan (SWPPP) for the purposes of enforcing erosion and sediment control <br />rules. The SWPPP will include erosion and sediment control methods that will be implemented <br />throughout the project. Silt fence, bio-rolls, erosion control blanket, and other best <br />management practices will be utilized where direct runoff might occur. Inlet protection will be <br />used to protect both the existing and new catch basins during construction. Street sweeping will <br />occur, as needed, on all paved street surfaces throughout the project, including intersecting <br />streets. Exposed soils and aggregate material will be watered as needed as a dust-control <br />measure. An erosion and sediment control plan sheet and storm water pollution prevention <br />plan will be created during the design phase of this project. Immediate turf establishment in <br />areas of soil disturbance will be required such as placing seed and erosion control blanket. After <br />street and utility work is completed, sod and/or hydro mulched seed will be placed as the <br />permanent turf establishment in all disturbed areas. The City, in coordination with the <br />watershed district, will closely monitor all erosion and sediment control measures throughout <br />the construction process. The selected contractor will be required to install all preventative <br />measures and maintain them as required by the City, CRWD, MPCA, and other regulatory <br />agencies. <br />C.0±¨µ ³¤ 5³¨«¨³¨¤² <br /> <br />Private utility companies have been notified that this project is being considered for construction <br />in 2015.
