I I I I r I I I I I I I Rural facilities planning has resulted in the ability to maintain the long-term viability of on-site system usage in Orono ’s rural service area. The result of providing municipal sewer to individual scattered neighborhoods within rural Orono has been elimination of pressure to "sewer rural Orono”. The historically high- densitv neighborhoods have been or will soon be sewered, and the vast majority of remaining properties in rural Orono contain adequate land for lone-term use of on-site sewage treatment. The Citv has identified those existing on-site systems which are nonconforming, and will continue to make steady progress towards replacing them with conforming on-site systems. Residential development in Orono’s 2-acre zones is expected to continue at a slow, steady pace for the next 20 years, at which time little additional land will be available for development. In the S-acre zone, only scattered subdivision opportunities remain, with a potential for no more than 30-40 additional homes to be constructed. ■new table- Summar}' of Rural Facilities Planning 1974-1999 Year Planning Activity 1974 ORONO GROUNDWATER STUDY by McCombs Knutson Associates, studied groundwater contamination from Stubbs Bay, Crystal Bay and Brown’s Bay; concluded that lake and well contamination was not present, but shallow groundwater contamination was present which could lead to insufficiently treated water reaching the lake from near-shore systems. 1975 PRELIMINARY SANITARY SEWER ENGINEERING REPORT BY McCombs Knutson Associates, reviewed alternative solutions for was ewater treatmnet in the Stubbs Bay Area. Proposed either connection to (then proposed) Orono-l.ong Lake interceptor or installation of a community drainfield system. Neither solution was implemented; MPCA was not in a position to approve the community system and the interceptor route was not > ?t determined. 1977 ORONO COMPREHENSIVE SEWER PLAN identified final preferred route of Orono-Long Lake interceptor to pass near all rural cluster study areas except Stubbs Bay, allowing for future neighborhood connections. 1978 ON-SITE SEWAGE TREATM.ENT ORDINANCE NO. 210 adopted, full-time On-Site Manager hired, first area-wide inspections completed in 1978-79 resulted in identification of 5 rural clusters needing further stu_v. 1979 STUBBS BAY STUDY AREA MORATORIUM established to restrict new development or expansion of uses pending completion of study to resolve sewage treatment deficiencies in the area.. Preliminary report by Bonestroo, Rosene, Anderlik & Associates updated the 1975 McCombs study as to costs. 1979 cn Y OF MEDINA PRELIMINARY ENGINEERING REPORT resulted in the Orono-Long Lake-Medina Sewer Agreement to allow permanent connection of Orono s Hackberry Hills neighborhood sewer to the Long Lake sy stem, and allow ed construction of sewer connection from Medina's Momingside neighborhood to Orono/Long Lake system. Resulted in the construction of a new by-pass trunk line through Long Lake, w ith allocation of units to each citv. CMP 6-49
