�e minary Plat of Fox Bend - Septic System Testing u t 22, 1989 �g 4 of 4 i al Cc�nents - Each proposed lot appears to have suitable primary and �t rnate drainfield sites. On some lots, the primary and lt nate sites shown are the onl possible sites available. On th lots, it is likely that additional testing could find a �lm r of potential sites, al lowing additional f lexibility in qu placement. In each case, drainfield sites have been designed to meet he inimum 20' setback from property lines, and 75' setbacks ro designated wetlands. � On the majority of lots, estreme cantion must be taken ur ' g construction of improvements to the property. Road on ruction will take place within 50' of tested drainfield it on at least 6 of 17 lots, and on 2 lots the sites are e41 ively near the area proposed to be graded to provide a �'te tion basin. I would recommend that each lot have drainfield ijte protected by snow fence total ly surrounding the drainfield it at a distance 20' from the boundaries of each drainfield ys m. Additionally, when road construction plans are ub tted, I would like to review them to determine where road ut ould have a potential impact on drainfield sites. Out of 34 drainfield sites tested, 29 require mound systems d would allow a trench-type system. Each lot has primary and lt i nate sites designated. It would not be surprising if as ny s 20$ of the sites ultimately will have to be re-tested due o t e buyer's preference for house sites near or conflicting '�h rainfields. Some lots are extremely limited for potential �i field sites, others provide a degree of f Iexibility in house p �c ent. , iven the above facts, concerns, and constraints, I would r �o end approval of the subdivision as proposed. Accompanying t is emo is a topographic survey of the preliminary plat showing p te tial house Iocations and locations of both primary and a te ate drainfield sites.
