. . Mr. Dan Winkel .- February 2, 1995 Page Two I In either case, the lift station should be placed in or near the Harnline Avenue right-of-way to allow future connection with 10""1i7ed development. The lift station should also be deep enough to allow such localized development to occur. The actual depth of the lift station . is dependent upon the City's intentions for development within this area. If it is anticipated that residential homes will eventually be built in this area, the lift station design must consider the possibility of full baSj:ments. Yet the development of the area under . commercial/light industrial zoning may not warrant such design considerations. The development issue leads to our next concern, which is the degree to which the City . intends to develop this area in the next 10 to 20 years. We would recommend that the lift station be sized for the development of the immediate area adjacent to the National Guard's facility. This is due to the construction of the TCAAP interceptor at the northwest corner . of the TCAAP facility, which is adequate to serve the entire TCAAP area. Moreover, the City's efforts to oversize that interceptor included design considerations for the area in the I vicinity of the National Guard facilities. Development of another sewer system to serve a large area in this portion of the TCAAP facility would result in an unnecessary duplication of efforts on behalf of the City of Arden Hills. Ie In summary, it is our recommendation that the sanitary sewer be installed to the manhole south of Trunk Highway 96 and approximately 1,300 feet west of Hamline A venue. The I lift station should be sized to accommodate the specific type and amount of development the City envisions within this area, prior to the extension of utility service from the north. Finally, both the sewer and water improvements should be completed with due I consideration of the issues presented in the enclosed site review memorandum. We hope this letter adequately addresses your needs with regard to this issue. Please I contact our office if you have questions or require further clarification on any of the issues presented in this review. . Sincerely, I MSA, CONSULTING ENGINEERS . GJS:tw .
