p g; + i rises appeciably higher than that and there really isn 't that much room M r here. Are you disputing the person who went down to measure the distances? RP:I 'm saying this could have been done in August, an_d,'-,the test pit was done in the. front lobcorner f the lot, nowhere near where the system is going.I would be concerned if I were purchasing a house there because of the high water lvl .Plus I wwn the house over here with a garage which is a foot or two over the foundation, above the road, rather. The road run-off accumulates on this lot, the catch basins don't do mmuch. This lot takes all the grater from 405,406 and from the top of Radcliff. Now where is the water going to go? I don't wart to run the r i st of getting flooded in the garage or basement. Mr B: The drainage problems fall under the purview of the con Cori, if building a house would impact the wetlands. Our concern is with the three variances requested.Look i n t Howlands report and the survey outlay, it seers the delineation of the wetland, the line that shows pits 5S 1 , 554, 553 were taken to show soil characteristics. CC; Rather than just examine vegetation , we did soil analysis as well . It-'s like a puddle if the edge of it moves after a RAIN, IT oESN"T MEAN THE EDGE of A WETLAND HAS MOVED, It means the edge of- the waterline has moved. RP: Ultimately, where is the water going to go CD: Ultimately it percolates back down. At what rate isn 't important. There' s a soils buffer between the wetland and the leaching area-. It will perc pervertically, not s.id w , . P: Flow does this affect shallow water wells? Basically all the water is running in the direction of that wetland. l express concern that theme will be three septic systems essentially upland from my well -My well was moved three t i'mes to obtain the best available water. Nay lot is 395. 1 have gone to great expense drilling and sampling pry water. My water quality is acceptable now, I 'd hate to see that upset by adding too many septic systems in that area. My well is downhill from the proposed septic system. GC: U fortu nat l y we all have that problem. It can't be avoided. I wonder in ray area how many more septic systems are cooing in. P: I 've seen typically in this area systems staggered diagonally, in this case three systems are in line, and I 'm picking up the shortest distance possible. . Most of them zig-zag, a pair of wells, a pair of septics. . . C:It loofas like he's tried to put the trench as far away as possible i-n the far corner. He's adding to that area but he's trying to seep it in that area. Mr B: Looking ng apt the flow lines the trench is at a 561 level , going down to 5 ' at the pond. The pond is at 491 perhaps. If the flow line is at right angle to the topography so the flow will be going in the direction of the wetland.The soil analysis indicates that there would no danger to the wetland b c'ause of the nature of the upland soil . The fil- tration il- trkadori from the leaching r% a w ould be downward, th r^ f rthere is no lateral prblern. This is on the Ia t page of (lowland's report. a dI . F f GC: I see the existing well on 396 is -in ,that corner, 3924 1s theme and the wel 1 that you proposed to put in is basically there. The well on 405 rust be on the other' corner. . The septic seers to be in the proper plc .That's the most logical place for it to go. RP: I noticed that they}haven ',t done a .perc test in th i as corner, it was done in the .front corner. Mr B: We will be conducting a soil examination at the time of excavation. Sometimes at R p rc test is done with full know l edge of w� re the system is going, other tires it isn 't known. once the plans arrive, i f the site of the test hole is awya from where the system is going, we require an additional soil examination at the time of installation. To race sure that the soil conditions aro adequate for the system'.If it isn 't adequate then everything will stop until a proper location i s found. P: I was present when they did the prc test and I recall that water was encountered at around 51-51/2' . GC: Here's- the pit on the plan and it shows that they hit water at 61 . CC : The quality of the soil i good, it's maintaining proper distance t groundwater that' s important here. GC': Mr. B just assured. you that before the sY steer goes in another h soil examination will be conducted. It will be inspected prior to backfilling by one of our i nspctr .So again we' ll go back.That again is part of the protection for your.
