Rum River 2>rairie Preliminary .Plat Review February 28, 2006 2 of 4 Landscaping Plan: The following comments are offered regarding the landscaping plan, dated February 2, 20136; City Code requires that every single family lot receive two (2) overstory trees, consisting of · mL'rture of corfiferous and deciduous species (not less than 25% of either type). Your submitted landscape plan proposes to plant 49 trees and save six of the existing trees. Filly-two trees are required for 26 Iots, and a combination of newly planted and preserved trees can be used to meet that requirements. The City strongly recommends the installation of a berm and additional landscaping along the rear of the lots proposed to front Arms~zung Boulevard. The purpose of this is to mitigate potential noise complaints and provide an appealing road frontage to Armstrong Boulevard. Tree Preservation Plan: It is unclear which trees will be part of any tree preservation efforts taken with existing trees on the Rum R/vet Prairie plat. Please submit a revised site plan indicating the location of any trees to be saved if you wish to gain landscaping credit for preserved trees. Wetlands: It appears that there is a small wetland located on the Kelly Acres site. This should be verified by a wetland delineator and delineated on the site plan. However, it does not appear that there are any significant wetlands located in the development area. The stormwater calculations must be submitted to the Lower Rum' River Water Management Organization (LRKWMO) for review and approyal. A permit must be obtained from the LRRWMO. A N-PDES permit is also required with a courtesy copy of the permit sent to the City of 1~ amsey. Drainage and Grading: Ali Iots with grade less than 2% drainage will require a certificate of grading prior to occupancy. A building summary is required showing lot, block, lowest opening, garage op~ning, I00 year flood elevation pond wetland, centerline elevation; front yard slope (%), rear yard slope (%)and a list of the lots require grading certificates. The city does not allow infiltration basins. Please revise the grading plan showing elevations at lot corners and proposed spot elevations. Also, the drainage arrows and contours do not match. Please submit a revised drainage plan that reconciles the drainage areas and provide revisions to drainage plan after revising streets to show a cul-de-sac at the terminus of Wolverine Street. Further city comments will follow revisions to the preliminary grading, drainage, and utility plans. Streets and Access: Staff would like to explore shifling Wolverine Street to the west to more closely align with existing Wolverine Street north of County Road 63.. Please submit a revised plan showing options for the realignment of Wolverine Street. The City is requiring that proposed Wolverine Street end in a cul-de-sac at the Tiger Street intersection to avoid stacking conflicts on Tiger Street and Armstrong Blvd. Thus, the City will also be requiring the construction of proposed 171st Avenue within the proposed Kelly Acres 21
