Main Street Village page 9 • The following summarizes the project proposal: • Gross Site Area 28.3 acres Upland Area 24.0 acres Wetland 4.3 acres Currently Proposed Development Area including Outlot A 8.7 acres Water and Sanitary Sewer: The project will be served by municipal utilities. Ample capacity exists in the systems. Water looping through the development ultimately will be needed for proper flow. Wetlands and Stormwater Management: The Rice Creek Watershed District (RCWD) approved the delineation of the wetlands and the mitigation plan in 2006. However, that mitigation plan application did not include wetland fill and mitigation necessary for the future access route (with the southern driveway). Since this will be the main access to the retail center in the future, it is vital to know if this `road' can be constructed. The wetland impacts and mitigation are an integral part of this question. A new wetland delineation was submitted to, reviewed, and approved by the RCWD. This included an amendment to the delineation of the large, southern wetland. Drainage and utility easements must be established that cover and extend 10' beyond the wetlands, in accordance with City requirements. There will be an easement over the incidental wetlands in Outlot C because they will become stormwater ponds. There is no designated floodplain on the site as shown on the FEMA map. The plans show little space for snow storage after plowing. A snow storage area must be designated or snow must be completely removed from the site. This report discusses the AUAR requirements for stormwater management in a previous section. Roads, Access, Traffic, Circulation: A traffic study was prepared for the development. The study analyzes the current proposal (phase one), full development of the site (phase 2), and year 2030. The study assumes the existing bank road will be a full access point with phase one of the development, but be converted to right- in/right -out only with phase two. As to the southern access, it will function properly with a stop sign with full development but will require a traffic signal by 2030 because of the increasing background traffic. The intersection of Otter Lake Road and Main St. will function well until 2030. The AUAR's S traffic analysis also recognized that this intersection will fail at that time. That is, this will occur without the proposed Main St. Village project. This is an important transportation
