"1Jeeds Surveys �or U�sewerea rreas" <br /> for various locations ki�hin tne City of Orono. In mos� c�ses , <br /> these aieas were oeveloped more than twenty years ago at a time <br /> when aeneral knowledge about septic s��stems , drainfield siting , <br /> 371G� S011 SU1�abilities 4.'�CS minimal a� beSt. TOGc}' , �hese <br /> developnen�= on small lots �ith steep slopes , clay soils , or <br /> hi�h waier tables are comine bacY. to haunt Ls ki�h �ailina septic <br /> systems posina health and pollution hazards in tne shoreland areas <br /> of Lake Minnetonka. ` <br /> Orono ' s basic philosophy is that further high-density de��elopment <br /> would be det-imenLal to �he Lake ?�Sinnetonka ecosystem_ This type <br /> of develormen� normally occurs with the ad.�ent cf municipal se�.ers. <br /> T�ere�ore, we intend to develop with septic systems on two anc <br /> r five acre lots in the existing unsewered are�s , with, an active <br /> permanent program of plan review, construction inspec�ion, and <br /> regular existing system inspection with mandatory maintenance_ <br /> This will necessarily include finding alternatives to septic svstem"s <br /> in a iek existing developments �:here site conditions or lot sizes <br /> Tr�ake it essen�ially imposs�ble to adequately treat se�:aae with or.- <br /> site methods. Once these existing problen� areas are remedied , all <br /> future development should continue in an orderly fashion without <br /> the problem of "leap-frogging sewers" . <br /> Our present priority list for remedying existing problems is : <br /> 1. Minnetonka Bluffs - Feasibility Study about to be called <br /> - (construction 1980?) <br /> 2 . Shoreline Drive - Feasibility Study about to be called <br /> (construction 1980?) <br /> 3. Crystal Bay Area - Proposed within three years of interceptor <br /> completion - 1983? <br />
