We also understand that this new development will have municipal sewer with gravity sewer discharging into the existing Medina Morningside sanitary sewer lift station. The forcemain from this lift station flows south to County Road 6 then west eventually discharging into an Orono gravity sewer in Old Crystal Bay Road. This gravity sewer then flows south and through the City of Long Lake to a Metro Waste lift station, llie existing Medina Morningside sewer service through Orono and Long Lake is per the terms of an existing Long Lake/Orono/Medina sewer service agreement dated August 10,1981. The provision of sanitary sewer service to the Keller Estates development will require modification of the 1981 sewer agreement and approval of the Orono City Council and Long Lake City Council. A project to reconfigure the existing sewer system through Orono and Long Lake for the new Highway 12 bypass project is currently under construction. This project will require revisions to the existing three city sewer agreement. My understanding is that presently there are sewer capacity issues in Long Lake and the completion of the new sewer system this summer will eliminate the sewer capacity issues and substantially reduce the length of Long Lake municipal sewer that is included in the sewer agreement. The existing sewer with Orono and Medina flow goes all the way through Long Lake to the Metro Sewer lift station located in eastern Long Lake. The new City sewer will discharge into a Metro Sewer Interceptor at Willow Drive. The only Long Lake sewer in the agreement will be from the Orono City limits to Willow Drive. There should be adequate capacity in the Orono, Long Lake, and Metro Waste sewer systems to handle the additional flow from the proposed Keller Estates development. Traffic Impact Issues Orono City staff has reviewed and discussed the tralTic impacts from the proposed Keller Estates Development, and we have concerns about the increased traffic at the Willow Driv&'County Road 6 intersection. Using a typical design value of 10 vehicle trips per day for each home, tliis development will add 210 vehicle trips per day to W'illow Drive with the majority of these trips using the Willow Drivc/County Road 6 intersection. There arc concerns about traffic safety at this intersection, as in the past several years there have been numerous personal injury accidents and two traffic f.italities at this intersection. The City of Orono recently completed a traftlc management study in this area, and the preliminary two- hour traffic counts at the Willow Drivc/County Road 6 intersection indicate that a traffic signal may be warranted. The City of Orono has requested that Hennepin County complete an eight-hour traffic count at this intersection to evaluate the feasibility of installing a traffic signal. Th>.' possible schedule and funding for the installation of a traffic signal at this intersection is unknown at this time. However, it is a certainty that the installation of a traffic signal will require cost participation from the local units of government as all new signals on Hermepin County Roads require local cost participation. Hennepin County has jurisdiction on the east and west legs of the Willow Drive/County Road 6 intersection, and the City of Orono has jurisdiction on the north and south intersection legs.
