Please note that the septic tank and leach field appeared to be closer than ten feet to the property line. Though we have not completed an asbuilt survey of the property, it appears that the septic tank is five feet from the property line and the absorption field is four feet from the property line (see sheet 3 of 5). The lot line encroachment occurs against the 10ff State Right of Way for Eagle River Road. The encroachment will not impact any of the adjacent property owners. I would appreciate your review and approval of the enclosed documents, including the waiver to the Lot Line Separation.

RECEIVED BY: DATE: DATE: DHI CONSULTING Civil · Surveying ENGINEERS · Planning W.O. 97312 SITE NARRATIVE Project: Lot 69A Bower Subdivision This is a 53535 square feet parcel which is bordered on three sides (north, south, and west) by developed lots. The easterly side is boarded by a 240' state Right of Way for Eagle River Road. The lots to the north, west and south are immediately adjacent to the subject lot. The subject lot is undeveloped and the septic system is design for a 3 bedroom home. WELL: The lot immediately to the north has an approved well and septic system. None of the other adjacent lots have any well or septic improvements. The only lot impacted by the proposed well is immediately to the south. Do to the steep contours on the south lot, the small area impacted by the proposed protective well radius will not adversely effect the future placement of well and septic systems on the lot. SEPTIC SYSTEMS: The lot on north has an existing septic systems. Neither the existing or proposed systems will have an impact each other. The proposed septic system does not impact any of the other adjacent lots. DRAINAGE: The drainage in this area is generally from east to west. This lot has a gentle slope in the area of the proposed house and septic system. The westerly half of the lot has steep slopes in excess of 40%. The septic and the reserve system will set over 70' away this slope. (See attached drawing). There is adequate relief to allow the lot to be graded in such a way that no ponding will occur. There are no drainage channels or creeks within 200 feet of the proposed system. SUMMARY: The placement of the proposed septic system and well meet all requirements of Title 15; and will have minimum or no impact on adjacent lots. 312nar.rep Page 1 of 6 Dimond Center Tower, 5th Floor · 800 E.
