CITY OF ORONO CRYSTAL. BAY SEWER ASSESSM}J41' HEARING APRIL 22, 1985 - 7:00 P.M. ORONO MIDDLE SCHOOL AUDITORIUM The Crystal Bay neighborhood of. Orono is located on Brown Road South (County Road 146) north of the intersection with North Shore Drive (County Road 51) and comprises approximately 80 existing residences. Originally platted prior to 1900 into 50- foot lots, the area's general patt- rn of development over the years has been single family hor* �n parcels of 1/2 acre or less. In fact, 31% of the propert are 1/4 acre or smaller. WHY IS INSTALLATION OF MUNICIPAL SEWER PROPOSED FOR CRYSTAI, BAY? A small but significant portion (about 1 in 8) of the septic systems serving these homes have experienced failure in recent years. A review of the design, location, size and condition of existing septic systems in the area has shown that the majority are quite substandard, and these continue to function adequately mainly due the sandier soils in this area. A review of each property ha. .ndicated that 26% of the existing properties do not have adequate lot area to replace existing septic systems with a new system meeting the minimum acceptable code standards if failure occurs. An additional 45% are severely limited in possible expansion area and would encounter major difficulties in trying to provide a conforming system. Although the majority of systems are not failing at this time, the potential for future failures is high, with a poor outlook for adequate repairs. The Crystal Bay area is one of ve rural housing clusters identified in the Orono Community Management Plan as requiring a special Alternative Waste Management Study. Three of the five clusters have been sewered since the Plan was adopted. Only Crystal Bay and certain portions of the Stubbs Bay area remain under consideration. Crystal Bay is located adjacent to the MWCC's Orono -Long Lake Interceptor, which offers the opportunity to connect into the Metropolitan Sewer System. WHAT FACTORS CONTRIBUTE TO THE COSTS OF THIS PROJECT? The sewer system proposed to serve Crystal Bay will cost $900,000, or $10,850 per unit. The cost includes installation of the sewer lines and lift station to discharge into the Inter- ceptor. Also, included is restoration of the roadways to their existing width. Cost of the project is somewhat higher than similar projects due to extreme depths of excavation (up to 271) required in some locations to provide a gravity flow system, thereby reducing maintenance costs.
