Shade Tree Creek Preliminary Plat Review-3 March 24, 2006 3 of 5 Management Organization Permit (LLRWMO) is required for this plat. Final plat approval will be contingent on receipt of this permit. It also appears that wetland impact and mitigation is proposed. Approximately 15,000 square feet of wetland impact is proposed. The Wetland Conservation Act requires any impact to be mitigated at a 2 to 1 ratio. The proposed plat indicates approximately 15,000 square feet of mitigation. An additional 15,000 square feet of mitigation is required, and should be indicated on the final plat. Drainage and Grading: · Retaining walls need to signed by an Engineer and submitted to the City of Ramsey for approval. Any retaining walls higher than 42" must have an approved railing or fence. · The storm water calculations must be submitted to the Lower Rum River Water Management Organization (LRRWMO) for review and approval. · A NPDES permit is also required with a courtesy copy of the City of Ramsey. · The proposed lift station must be encumbered with a drainage and utility easement Streets and Access: The preliminary plat proposes to provide a public street (Erkium Street) from 177th Avenue to service the proposed 16 single family lots, ending in a cul-de-sac. Staff is requesting that this road be constructed to the plat boundary on the south and must be constructed to urban standards to the southernmost lot. The remainder of Erkium Street can be paved to rural standards: Wayne and Marian Meloche are the property owners south of the plat and currently have a private easement through your property under the Development Agreement for Riverbrook. This private road easement will need to be vacated once the public road is constructed. Additionally, an appeal to the City Council has been requested to reverse the Board of Adjustment's denial of a variance for cul-de-sac length for Erkium Street. If the variance appeal is not granted, the preliminary plat will need to be revised to accommodate a shorter cul-de-sac. The plan also shows a road to the west, which must be constructed to rural road standards to the extent of the parcel in order to facilitate better access to the proposed 16 lots and to provide access to the community drainfield. It is preferred that a connection be made to the west to 177th Avenue. The City is exploring options for obtaining right-of-way to make that connection continuous ali the way to Hw. 47 to the west. A service road wiI1 be required for construction, with a minimum of a Class 5 surface, to access the area of the proposed common septic system. During construction, existing Erkium Street & 177th Avenue must remain passable at all times. Sidewalks: A sidewalk will be required along one side of Erkium Street. -301-
