To: Mayor Peterson and Orono City Council Ron Moorse, City Administrator From: Michael P. Gaff ron, Asst Planning & Zoning Administrator Date: February 24, 1992 4(C/L"—\R4 Subject: Stubbs Bay Sewer Project - Issues to be Resolved ti � ?.. �S�r The intent of this memo is to provide an analysis and recommendation for each of the issues identified in the cover outline. I. Area Inclusions. The project has been divided into 5 distinct sub-areas for bidding purposes. Stubbs Bay Northwest/Northeast/Bayside East has been determined from an engineering standpoint to be the minimum feasible project based on the potential "add- on" areas and the designation of trunks vs. laterals. Each of the add-on areas (Bederwood, Bayside North, Oxford, and Cygnet) can be included or excluded on their own merits without affecting the feasibility of other areas. A. Northwest/Northeast/Bayside East. This basic project area includes a total of 82 units more or less. The final determination for number of units is dependent on decisions in Item II below. For the most part, these are relatively small lots as compared to the rest of the Stubbs Bay area, and in many cases have marginal septic systems with poor potential for replacement. Estimated Unit Cost: Northwest - $12,440; Northeast - $12,450; Baside East - $10,650. Staff Recommendation: Inclusion. B. Bederwood. The Bederwood area, including 10 houses plus 1 vacant lot, will require a separate lateral system and a grinder pump station. 5 of the lots are 1.6 acre or greater, the remaining 5 are 0.8 acre or smaller. Of these 10 , one is a failing system with poor potential for a conforming replacement system, 2 others would be considered as marginal but still working. Because of the lift station, the cost of serving this area is relatively high. Estimated Unit Cost: $18,190 . Staff Recommendation: Trunk assessment now, construct and assess lateral now if neighborhood requests.
