BOX 240773 ANCHORAGE, ALASKA 99524 February. 13, 1995 LanTech, Inc. 440 W. Benson Anchorage, AK 99503 970 0 5 Attention: Tom Dreyer Subject: Hokama Heights Subdivision, Addition No. 1 Septic System Site Plan Dear Tom: Attached is the septic system site plan, backup testhole information and percolation data for Lots 1 through 5 of Hokama Heights Subdivision, Addition No. 1. Testholes were originally dug in March of 1994 with most of the field data collected at that time. Monitor tubes placed in March of 1994 were monitored for groundwater elevation during breakup of 1994 and the following summer. No accumulation was noted at any time. Groundwater does not appear to be a problem in this subdivision. Only 1 testhole was excavated on Lot 4. Based on the uniform results found in all the testholes throughout the subdivision, however, it appears safe to assume that soil conditions on Lot 4 are also uniform. If necessary, additional testholes can be excavated to verify this assumption. Soil conditions in the subdivision are generally silty sands with percolation rates ranging from 31 to 60 minutes. A total of 19 testholes have been excavated over the entire subdivision with similar soil conditions found in every hole. A shallow layer of organic material is underlain by the silty sand. Though not ideal conditions for absorption trenches the proposed lots will support onsite septic systems. The surface of Lots 4 and 5 slope rapidly from north to south. At times the slope exceeds 30%. For this reason we chose to identify three septic system sites for each lot. These sites are placed in locations which provide a minimum 50' separation distance from a 25% slope as mandated by Municipal Ordinance. The surface on the remainder of the lots is much flatter with slopes ranging from 4% to 6% in a north to south direction. We have identified 16,000 square foot reserve areas for septic systems on Lots 1, 2 and 3 as any location within these reserve areas appears acceptable Hokama Heights, Addition No. 1 February 13, 1995 Page Two for an absorption trench. The systems designed for Lots 4 and 5 are 5' wide shallow trenches and designed for three bedroom homes. The laterals in some cases are located 6' below the surface as the best material is found at this depth and additional distance is provided from the steep slopes. None of the slopes near the systems exceed the 25% maximum. The existing home on Lot 3 is currently served by a system which does not meet current Municipal requirements. Previous correspondence indicates this system must be upgraded before this subdivision can be recorded. We have attempted, however, to utilize the well on Lot 3. Sufficient space is available outside the 100' protective radius for the 16,000 square foot reserve area. The protective radius and reserve area are shown on the attached site plan. The wells serving the proposed lots must be located in the northern portion of the lot to provide the required 10ft separation distance from the septic systems. The systems are also located at least 100' from wells located on adjacent lots. It may be necessary to place the wells on Lots 1 and 2 in the Landscaping Easement to provide the minimum 100' separation: Please let me know if you have any questions or comments.

Box 196650 Anchorage, Alaska 99519-8160 February 13, 1995 ATTN: Jerry Weaver & Planning Staff RE: Hokama Heights, Addition # 1, preliminary plat. Concerning Griffin Road. This letter serves to clarify our position that we propose to not access Griffin Road or construct Griffin Road along the south boundary of this subdivision, as we also did not on Hokama Heights short plat, recorded P-94-119, case S-9575. The reasons are; 1) It makes good common sense for the driveways to access through our proposed access easement to a common driveway approach onto DeArmoun Road, on the northwest comer of lot 3. An access point here conforms to safety regulations and sight distances. We also are proposing a 30' natural landscaping easement adjacent te DeArmoun Road to help screen the driveway. 2) The side hill slope of the terrain along the Griffin Road right of way to the east and to the west is extremely steep, as shown on the topo map. A safe and legally conforming road along this corridor would be prohibitive to build, and for no ones benefit. 3) Griffin Road is not needed for any future growth potential, due to topographical considerations. The terrain south of Griffin is a steep bluff that descends down into the Rabbit Creek drainage. Currently the owners to the south of this parcel have a gravel driveway type of road built in the right of way that services them properly and adequately. Concerning Tract "A'. At this time, we are not developing Tract 'A'. Tract 'A' is a part of_this plat only because of the DeArmoun Road R.O.W. dedication, as per this plat. We request that no soil testing or road construction be required for this Tract. We are willing to put a note on the plat stating that Tract 'A' can not be developed at this time. At a future date, Tract 'A' will be subdivided into 4 lots, with a cul-de-sac at the north boundary line with Bager Lane.
