ARDEN HILLS SPECIAL CITY COUNCIL WORK SESSION – AUGUST 11, 2014 2 Sanitary Sewer  TCAAP, when operating, was served though a trunk line (built in 1994) that flows westerly under I-35W just south of CR H and ties into the Mounds View sewer system near the NE corner of CR 10/CR H. From there it flows westerly in the Mounds View system to a MCES lift station.  There is a three party agreement (Arden Hills, Mounds View and US Army) that allows this flow. That agreement will need to be redone between Arden Hills and Mounds View to deal with service for the redevelopment of TCAAP. Staff is working with the City Attorney, Mounds View and Ramsey County to coordinate the logistics of accomplishing this new agreement and taking over ownership of the existing infrastructure. Tom Lincoln, Kimley Horn, introduced himself to the Council and presented the preliminary sanitary sewer system for the TCAAP site. He reported that the model and design for utilities included a maximum of 1,700 homes. He explained that he would be speaking with the City of Roseville regarding the water that would be supplied to the site. He noted that the expense of the sanitary sewer and water systems on TCAAP would be the City’s responsibility and would typically be funded by the new development. Councilmember Holden asked if the proposed model would address the utility needs north of the Thumb (MnDOT Training Facility and Truck Station) and asked why the City of Arden Hills would not want to supply water to all areas north of the Thumb. Mr. Lincoln commented that it would be feasible to run utilities in the areas north of the Thumb where the Minnesota Driver’s License Exam Center and the Fleet Surplus building are located, but that it would not be cost-effective to supply water to the areas north of that such as the MnDOT Training Facility and Truck Station. Further discussion ensued regarding the current utilities located on the thumb and the MnDOT facility. Councilmember Holden asked if there would be any issues getting additional water from the City of Roseville. Public Works Director Maurer stated that this should not be a concern. Councilmember Holden inquired who would be responsible for maintaining the existing sewer lines leaving TCAAP over to the MCES Lift Station. Public Works Director Maurer indicated that the maintenance of any of the lines in the Mounds View system would be the responsibility of the City of Mounds View. The existing sanitary sewer pipes leaving TCAAP, flowing to the Mounds View system, were the responsibility of the Army but Arden Hills will be taking over that maintenance responsibility. Mayor Grant asked who would be responsible for I&I.
