Benson Anchorage, AK 99503 Attention: Tom Dreyer Subject: Lot 3A, Prator Subdivision Soils Exploration Dear Tom: Attached is the Site Plan and Septic System Design for the subject lot. Testhole Nos. 4, 5 and 6 revealed a poorly to well graded gravel layer at depths from 4' to 10'. This layer percolates at a rate under 5 minutes per inch and is excellent for an onsite septic system. Our recommendation is to place a bed system atop or within the gravel layer. The dimensions of the system to accomodate a 4 bedroom house must be a minimum of 18' X 42'. The attached plan and design indicate the preferred areas for the system to maintain the setback limit from the steep slope to the west. Testhole data was previously submitted to you. Please advise if you need additional information. Sincerely, Michael E. Anderson, P.E.

Benson Anchorage, AK Attention: Tom Dreyer Subject: 99503 Lot lA & Lot 2A, Prator Subdivision Subsurface Soils Investigation Dear Tom: On October 4, and again on October 7, a subsurface soils investigation conducted on Lot lA and Lot 2A of the proposed Prator Subdivision. was The was to determine if two additional septic placed on each lot. The area for the sites the property which serves both lots. It is, "C" well and requires a minimum 150' purpose of the investigation systems could be successfully was restricted by the well on therefore, classified a Class · separation from all septic tanks and drainfields. Testboles were completed utilizing a backhoe. Monitor tubes were set in each hole and percolation tests run to establish design criteria. Four testholes were excavated in addition to the verification of two testholes previously dug by Polarconsult Alaska, Inc. for the design of the prilnary system on Lot lA. The boles were dug to depths approxiinating 20' and the soils encountered logged on the attacbed forms. On October 6, October 12, and October 14, the soils were presoake~ and tested to determine percolation rates of the soils proposed for acc~eptance of septic effluent. In addition, the water table was monitored during this period to determine whether it would affect placement of the systems. Neither during excavation nor during the monitoring period, which is normally one of the wettest periods of the year was any water evident. The soils encountered in the exploration and the percolation rates obtained indicate excellent conditions for the placement of the onsite systems. Site No. 2 for Lot lA is designed for placement parallel to the primary system currently in use. It is located 15' northwest of the present system and is LanTech, Inc. October 27, 1993 Page Two designed utilizing the same criteria for the present system and has the same dimensions. Site No. 3 for Lot lA is located 20' from the southwest end of the present system and parallel to the western lot line. The design of this system is based on Testhole No. 1 completed by Polarconsult and verified by our investigation. Both sites are shown on the attached System Site' Plan and their respective designs as well as testhole information is also included. Site No. 2A for Lot 2A is located parallel to ground contours and centered on Testhole No. 1. It is designed for a four bedroom home and based on a percolation rate of 27 minutes-per inch. Site No. 3A is also located parallel to ground contours and centered on Testhole No. 2. It is also designed for a four bedroom home and similarly based on a percolation rate of 27 minutes per' inch. Both are deep trench systems and are well suited for conditions found in the testholes. These sites are shown on the attached System Site Plan and their respective designs as well as testhole information is also included. In summary, we have successfully located and designed two additional onsite septic systems for each lot. All pertinent information is included for your review.

A well for Lot 3A can be expected to be at least 225' to 250' deep and will probably yield around 3 gallons per minute. This yield is acceptable to support a 4 bedroom home. Our study of the surrounding properties indicates that a well can be satisfactorily placed on Lot 3A, Prator Subdivision. Please advise if you have any questions or comments. Sincerely, Michael E.

Benson Anchorage, AK Attention: Subject: 99503 Tom Dreyer Lot 3A, Block 6, Prator Subdivision Soils Testhole Information Dear Tom: On August 20, 1993, and again on August 31, 1993, we conducted subsurface soils exploration and testing on the subject lot. The first day's excavations were limited to the north portion of the lot on either side of the small creek. These holes revealed a shallow layer of organic material underlain by a very dense silty soil. The silt was nearly impenetrable with the backhoe and would not absorb water during the percolation testing process. Efforts were abandoned in this area due to results obtained. On the second day testholes were dug closer to the east lot line along Old Rabbit Creek Road. Again we encountered the shallow peat layer underlain by the dense silt. In this area, however, we were able to penetrate the silt to the gravel material beneath. This gravel lense ranged from a thickness of 2' at the north end of the excavation boundary to more than 8' at the southern end. Percolation tests run on the gravel layer indicated excellent absorption rates of 2 to 3 minutes per inch. The attached drawing delineates the boundaries of the septic system reserve area which includes the three testholes with the gravel lense. The location of the testholes indicates the gravel should be uniform throughout this proposed reserve area. This area computes to nearly 13,000 square feet. The Municipal Ordinance guiding Subdivision Standards requires a minimum of 10,000 square feet of total reserve area for a percolation rate between 1 and 5 minutes per inch. This area, therefore, satisfies the Lot 3A, Block 6 Prator Subdivision September 131 1993 Page Two requirements of the ordinance. Field measurements indicate the small creek traversing the lot is more than 100' away from the reserve area. The proposed well to serve the lot should be located in the northeast corner of the lot along Old Rabbit Creek Road. Placement in this area will provide the 100' separation distance from the reserve area and will not conflict with systems on adjacent lots. The topography of the lot s'lopes rapidly to the small stream and will make construction on the lot difficult. Much of the lot is unusable due to the steep slopes on either side of the creek. Depending on the location of the house a lift station may be required to deliver septic effluent to the proposed drainfield area. Included with this report are the Soils Logs and Percolation Tests run on the testholes located in the Septic Reserve Area. Soils Logs are also included for the testholes completed in the northern portion of the lot which were rejected for future septic system developement. In addition, a site plan delineating the limits of the reserve area along with the proposed location of the well and adjacent onsite systems is included for your use. Please advise if you have any questions or comments concerning the exploration work. Sincereley, Michael E.

Benson Anchorage, AK 99503 Attention: Tom Dreyer Subject: Lot lA & Lot 2A, Prator Subdivision Subsurface Soils Investigation Dear Tom: On October 4, and again on October 7, a subsurface soils investigation was conducted on Lot lA and Lot 2A of the proposed Prator Subdivision. The purpose of the investigation was to determine if two additional septic systems could be successfully placed on each lot. The area for the sites was restricted by the well on the property which serves both lots. It is, therefore, classified a Class "C" well and requires a minimum 150' separation from all septic tanks and drainfields. Testholes were completed utilizing a backhoe. Monitor tubes were set in each hole and percolation tests run to establish design criteria. Four testholes were excavated in addition to the verification of two testholes previously dug by Polarconsult Alaska, Inc. for the design of the primary system on Lot IA. The holes were dug to depths approximating 20' and the soils encountered logged on the attached forms. On October 6, October 12, and October 14, the soils were presoaked and tested to determine percolation rates of the soils proposed for acceptance of septic effluent. In addition, the water table was monitored during this period to determine whether it would affect placement of the systems. Neither during excavation nor during the monitoring period, which is normally one of the wettest periods of the year was any water evident. The soils encountered in the exploration and the percolation rates obtained indicate excellent conditions for the placement of the onsite systems. Site No. 2 for Lot lA is designed for placement parallel to the primary system currently in use. It is located 15' northwest of the present system and is LanTech, Inc. October 27, 1993 Page Two designed utilizing the same criteria for the present system and has the same dimensions. Site No. 3 for Lot lA is located 20' from the southwest end of the present system and parallel to the western lot line. The design of this system is based on Testhole No. 1 completed by Polarconsult and verified by our investigation. Both sites are shown on the attached System Site Plan and their respective designs as well as testhole information is also included. Site No. 2A for Lot 2A is located parallel to ground contours and centered on Testhole No. 1. It is designed for a four bedroom home and based on a percolation rate of 27 minutes per inch. Site No. 3A is also located parallel to ground contours and centered on Testhole No. 2. It is also designed for a four bedroom home and similarly based on a percolation rate of 27 minutes per' inch. Both are deep trench systems and are well suited for conditions found in the testholes. These sites are shown on the attached System Site Plan and their respective designs as well as testhole information is also included. In suminary, we have successfully located and designed two additional onsite septic systems for each lot. Ail pertinent information is included for your review. Please advise if you have any questions or comments concerning either the field investigation or the design of the individual systems. Sincerely, Michael E. Anderson, P.E. I SHEET NO. CALCULATED BY.
