MINUTES OF THE ORONO CITY COUNCIL MEETING Monday, October 10, 2016 7:00 o'clock p.m. 11. ##16-3855 ERIC AND ANDREA LARSON, 690 BROW ROAD NORTH, SCOTT AND JEANNE MABUSTH, 740 BROWN ROAD NORTH — SKETCH PLAN REVIEW (continued) - There are several subdivisions within the Rural Area that are developed as similar densities. - The plan will provide better stormwater and phosphorus control than 2 -acre buildable area. Goodrum stated their request to utilize the RPUD is simply to create a transitional and environmentally improved development. Goodrum commented the City has approved RPUDs in the past when it makes sense and that it makes sense in this situation. Rezoning the entire site to RPUD would allow them to effectively develop a 27 -acre site to match the surrounding area and will provide the ability to create complementary but individually unique lots within the site and keep the entire site under the Rural designation. The RPUD would also allow them to utilize existing sewer/water services. Goodrum noted they are requesting the two -acre lots also be included in the RPUD. Goodrum stated in order to meet the City's zoning codes, they would need to remove the existing pool, but by relocating the lot line under the RPUD, that pool would be allowed to remain. Goodrum indicated they are fine with the road being either private road instead of public. Goodrum noted the two -acre lots are to help prevent phosphorus runoff and meet the character of the neighborhood. Goodrum noted they are also proposing density for the entire site that is in the middle of the City's rural density. Other elements to the plan include the following: - The utilization of conservation principles. - Complements the Sugar Woods development. - Uses conservation principles. -Rural density within the site at .93. - Utilizing existing urban services - Improving runoff and water quality. Goodrum noted the Sugar Woods development has five lots along Brown Road and that they are proposing six lots. Goodrum stated in their view they have an excellent transitional development within a 20 -acre site. Andy Nelson, Westwood Professional Services, stated they placed a high importance on stormwater management. Some of the goals were to meet the requirements of the Minnehaha Creek Watershed District, which included runoff rate control, runoff volume control, and treatment of runoff to protect Long Lake. In order to accomplish those goals, a conservation stormwater design was created to exceed the goals of the MCWD. The tools used were a stormwater pond with irrigation reuse, sand iron filtration basins around the ponds, rain gardens, and pervious paver driveways. Nelson displayed a picture depicting the rain gardens, pervious pavers, and stormwater pond. Nelson noted the rain gardens will help provide treatment of runoff as well as provide an amenity to the property. Nelson pointed out their conservation design will exceed the goals of the MCWD and will reduce phosphorus by 87 percent over existing conditions and 25 percent over the standard MCWD design.
