.l August 29, 1979 Lee Starr t.',etrbpo]itan Council 300 I.letro Square But]ding .. · St. Paul, M~nnesota 55101 Re: Cost of Rum River Extension (Anoka Interceptor) Dear l_ee' ,' The City of Anoka n:ade a request to the Commission ~n F, ay, 1979 to extend the proposed easterly leg of the Anoka Interceptor from High,,,i, ay 47 to a point near the Rum River. The City made this request 'because they felt this extension ;.;ou]d allow all of the Dur, ham Oaks area to be served 'by gravity and also that the future installation of the interceptor in the corridor will. be complicated by the utilities, drainage and the street. This extension, however., is not necessary to provide service to the area s~nce the .. local collection system can d.ischarge to the interceptor at H~ghway 47. The Commission staff has' considered th~s request and has investigated other possibilities. Our meetings with Andover ascertained that they do not have a near future need for the connection of an ihterceptor to the existing Anoka i,lortheast Interceptor Therefore, inclusion of the Rum River extension in our current design would be only to provide Anoka with ease of service fo~ their pr'oposed local collection system and for the Conmission'to avoid addi.tional, construction costs in the future caused by installation of ~Jtilit~es.~n the interceptor corridor. The staff has investigated possible alianments in the field which would allow construction of 'the inte.cepuor subsequent to the install ation of local utilities in the street corridor..,The interceptor can still be constructed in the proposed corridor,' however, the construction costs would increase because of the existence of the utilities. Therefore, the preferred alternative wouid be on another alignment. In this respect, there appears to be a viable aligrunent through the north end of the fairgrounds, across the Rum ,,]ver, through ;he state hospital grounds in a northeasterly direction and to the existing Anoka llortheast Interceptor. The :two routes'are shown on /the attached exhibit. The alternative alignment through the fairgrounds and state hospital ;..,ill be of compatible costs and with .compatible con~struction diffi- ,culties. The.alternative route will require the ~cqu~sition of rights-of-way through public property.' These easements should be easily obtainable between public agencies. The alternative route could also restrict the development pattern of the property of the state hospital if this property is ever developed insomuch that
