\ ' Sv C.V’ the proposed pond construction will also impact the existing wetland. Plans should be submitted to the Minnehaha Creek Watershed District for review and approval. Final plans should include details regarding any required wetland mitigation. • Final grading plans should incorporate some type of best management practice to treat the storm water that is not routed to the proposed pond. • The plans indicate grading will be necessary onto the adjacent property to the west to construct the road; this will require temporary construction easements from the neighboring property owner. • The proposed intersection of Mackinnon Road and Watertown Road may present sight distance issues. A sight distance analysis of this proposed intersection should be submitted for review. • The imposed grading on all lots does not provide for any level areas in the backyards. It is unlikely buyers of these lots will be satisfied with the 20% to 25% grades shown across the backyards. It is likely home builders and property owners will construct retaining walls in the back yards to create some useable space. The city should review and consider what is acceptable for the likely grading revisions to all backyard areas. • Most proposed driveway grades are between 8% and 10%. The developer should note that 10% ^iveway grades arc the maximum allowed and should take care when designing and building homes so that the driveway grades do not exceed 10%. • Final plans should include a typical street section along with a geotechnical report and R- value recommendation. • The proposed project will disturb more than one acre and will require a storm water pollution prevention plan (S WPPP) for city review and approval and also for the necessary MPCA permit. • Once the final plans have been completed we will prepare an estimate of the total cost for the site improvonents to determine the amount of the financial guarantee required.
