Two test holes were excavated on the downhill side of the house pad and found various types of gravels, GP, for./feet then changed to SIPAMater was observed at 8' during the excavation and measured at 8.5 feet atter the 7 day monitoring peKM! The perc rate was measured at 2 minutes per inch, 3 feet below grade. A shallow 5-wide trench has been designed due to the high water table. The slope of the lot is 24 percent and a small creek does run along the north property line. The lot has a 24 percent continuous slope and has no cut banks with a slope greater than 25 percent within 100 feet of the system, see the drawing. This new septic system and well will not impact any of the neighboring properties due to the large lot layout. Please call me if you have any questions. Sincerely " 71.4.. Michael N.

Deviations from the approved design drawings shall be coordinated and approved by the engineer conducting the inspections. 0.3 All construction procedures and material used to construct the system shall comply with Municipal and State regulations. 0.4 Unless specifically agreed otherwise, the homeowner shall be responsible for finish grading areas after the system is constructed and soil is compacted and mounded over the wide trench disposal field and the Septic Tank. 1.0 SEPTIC TANK 1. I The 1000 Gallon septic tank shall have two compartments and shall comply with Municipality of Anchorage Requirements. 1.2 The septic tank shall be set level and shall be bedded as necessary to prevent settling or shifting of the tank. 1.3 Ail pipe connections to the septic tank shall be made with waterproof mechanical couplings. A cleanout shall be installed upstream of the tank within 5 feet of the house foundation. A double eleanout shall be installed downstream, within 5 feet of the septic tank. 2.0 SOIL ABSORPTION DRAINFIELD 2.1 The soil absorption drainfield shall consist of two 5' x 43.5' x~.5' trench with a total of 3.5 feet of sewer rock, 3.0 ft. beneath the perforated drain pipe. 2.2 The bottom of the excavated trench shall b.e level within +/- 2". And compacted or smeared surfaces shall be raked to allow for proper infiltration of effluent. This includes both the sides and bottom of the trench. 2.3 Sewer rock shall be 0.5 - 2.5", screened gravel with less than 3% passing the # 200 sieve. 2.4 Cleanout pipes and monitor tubes shall be 4" diameter and ionstalled as shown on the plans. The portion of the monitor tube extending through the sewer rock shall be perforated. All monitor tubes and cleanout pipes shall have waterproof caps conforming to Municipality of Anchorage Specifications. 3.0 ENGINEERING INSPECTIONS 3.1 A minimum of four engineering inspections will be required during construction of the system. One after the septic tank is set prior to its backfill, one after excavation of the absorption trench prior Io placement of sewer rock, one after placement of the sewer rock and the distribution piping, cleanouts and monitoring tubes are in place. The final inspection shall be after filter fabric is placed, the trench and the final grading are complete. 3.2 The contractor shall coordinate with the engineer at least 24 hours prior to start of construction. If the contractor desires, a site visit with the engineer prior to start of construction can be arranged. I PROBABLE IMPACTS TO ADJACENT PROPERTIES A) WELLS The proposed wastewater disposal system is designed in accordance with current Municipality of Anchorage Wastewater Disposal Regulations. The proposed drainfield will be constructed in accordance with these regulations. The separation distance from wells on adjacent properties is greater than 100 fi. Therefore no unacceptable impacts are expected on the wells located on a~acent properties. B) WASTEWATER SYSTEMS The new drainfield will be constructed above the road, approsimately in the center of the portion of this 20 (+) acre parcel. Therefore the separation distance from systems on adjacent lots will be more than 300 ft. Soils tests have shown the soil where the system is to be constructed is acceptable for and an on-site disposal system, therefore there should be no unacceptable impacts on adjacent wastewater disposal systems. C) RESERVED SPACE/SURFACE AND SUBSURFACE The large lot that this system will be constructed on has ample space, both surface and subsurface reserved for a replacement system. The proposed drainfteld should not affect adjacent properties. D) DKAINAGE The location of the drainfteld will not interfere with any drainage. The area disturbed during construction of the field will be graded and sloped so as to not pond water. Therefore this system shouldn't adversely affect adjacent properties.
