The request is to site the septic leach trench at 35' from the top of the hill. This request is to allow the homeowner to retain a buffer of 'trees between his home and Old Glen Highway. The engineering basis for this request is attached. I do not believe that our request will result in any type of seepage or discharge from the slope. The slope is well vegetated and there are no groundwater or impermeable layer concerns. Ground water mounding under the trench should not occur with this type of system and soil type. Please contact ]ne on this as we are holding construction for this approval. Sincerely, Louis A. Butera, P.E. EAGLE RIVER ENGINEERING SERVICES P. O.
