~50 ITIETRO/OURRE BLDfi. 7TH ,r., RC)BERT ~I'REfiI/' /Rlrll PRUL mFi 55K~ August 15, 1980 Mr. James Barton Metropolitan Council 300 Metro Square Bldg. St. Paul, MN 55101 RE: Interceptor Alternatives for Western Andover, Northeast Anoka and BasternRamsey' Dear Mr. Barton: In response'to our recent discussions about extensions of the Anoka Interceptor, I am herein presenting two feasible alternative alignments to compare with the presently selected one (F_achibit A). The first alternative (MWCCAlternative A, Exhibit B) was proposc~by Ray Payne of the Commission staff in a letter to Lee Start of your staff, dated August 29, 1979. This alternative avoids the Brom-DunhamOaks subdivision, but could cause development restrictions on the eastern side of the Rum River. The cost of tltis alternative is about the same as that for the selected plan (about 1.25 Million). The concept behind the second alternative alignment ('N~CC Alternative B, Exhibit C) resulted frem discussions with John Harrington and Jack Frost of your staff. This alternative combines sewer service benefits of the Andover e×~ension with the second Ramsey connection. The resulting alignment provides semTice to western Andover and eastern Ramsey as well as those contiguous areas of Anoka which have-been viewed as having potential for development. The connection for Ramseywould be somewhat parallel to Highway 47 and'be of greater benefit to the potential in- dustrial park development in northernAnoka. The alignment of this Andover e×~ension would avoid disruption of existing utility corridors and streets which is inherent in the selected alignment. The cost of this alternative is slightly less than the selected one at 1.15 million dollars. These alternates, or others which could possibly be developed, have not been studied to the degree that the selected alignment has. Previous studies did not address the timing issues for Ramsey and Andover which have come about in recent'years. Metropolitan Council's 208 places Ramsey's and Andover's need for sewer service after 1985. These alternatives offer viable options to the selected alignment which overcome complications of building am interceptor through the Dunham Oaks ar~a. It is difficult to accurately compare some.cost differences between these alternatives, yet, the costs between these alternatives describedhereinare quite comparable.
