. � STORM WATER MANAGEMENT The developmenfi team has had a pre-application meeting with the Minnehaha Creek Watershed District for the proposed Maxweil Bay Residences. The purpose of the meeting was to prepare a design that meets all of the districts requirements while also improves the environmental �ondition of the property. The MCWD was very helpful and was excited about the opportunity to provide input at the preliminary phase of the project that wi11 recluce and eliminate many of the current environmental impacts of the current use. We will need to acquire Minnehaha Creek Watershed District Permits for Erosion Control, Floodplain Fill, and Shoreline Stabilization. The Erosion Control and Floodplain Fill permit are straightforward and should be a simple process. �ur landscope architects and engineers plan to work with the watershed district to create an aesthetic4lly pleasing and environmentaf functioning shoreline landscape plan that will maximize the look and function of the shoreline. The most prevalent information we received from the MCWD is if we decrease the hard cover of the site 6y more than 10°�0, we satisfy the districts requirements for Phosphorous Removal, Volume Control, and Rate Control. We are reducing the existing hdrdcover from approximately 85°�o to 45%. We still plan to work with the MCWD to minimize storm water impacts from our development. We are investigating multiple options for storm water treatment that fit our site and minimize the environmental impacts of the proposed development. We have discussed the City of Orono storm water requirements with the city's engineering consultant, Bolton and Menk. The requirements of the City of Orono are equivalent with the Minnehaha Creek Watershed District. We plan to provide our design to both entities for review and to develop a plan that maximizes the effectivene5s of the storm water design. .�� *<� . ,�,� .. �'"'"fM'°'� ;n::,;� 1G ` " � By decreasing the hard cover by over lO��o, we are exempt from M innehaha Creek Watershed District ''�� 4 " ��.� �````' � �" `'�'��;� '' ' ^��`,��.._ ; . �•° ��_ G~�,..�:. requirements from Phosphorous Removal, Volume Control, and Rote Control.

At BohLand, It is our goa) to maximize the benefit in improving the storm water management and improving the water quality of Lake Minnetonka. With this development, we wifl pursue the best practices and creative thinking to improve the site beyond what we are required. TRAFFIC We have conc�ucted preliminary conversations with Hennepin County. Further design and study wil) be provided prior to a Preliminary Plat application. Some if the preliminary topics we have discussed include; 90 degree parc�llel entrance, potential additional right of way for bike path and number of drive access points and that there are no need for a turn �ane requirements.
