WHEREAS, a petition has been received from Kim and Linda Cresap to remove Notes 7 and 8 from Plat 95-93 that read: "Lots 4 and 5 shall be developed for a maximum residence size of 3 bedrooms." (Note 7), and "On-site systems as shown on the plat for Lots 4 and 5 shall be unavailable for use as driveways, parking areas or structures." (Note 8) for Lot 5, Hokama Heights Subdivision, Addition #1, located within the SE '/4, Section 27, T12N, R3W, S.M., Alaska, and WHEREAS, notices were published, posted and mailed and a public hearing was held January 6, 1999. NOW, THEREFORE, BE IT RESOLVED by the Platting Board that: The Board makes the following findings of fact: a. The petitioner is requesting removal of the plat note because the proposed building site is to be located where one of the septic system sites was platted. b. DHHS has approved three (3) alternative sites and does not object to removal of the plat notes for this lot only. C. Based on comments from DHHS, there is no longer a need to restrict the number of bedrooms on this lot and there are sufficient safeguards in place to ensure the property can support the development that is being proposed. The Board APPROVES the removal of Notes 7 and 8 on Plat 95-93 for Lot 5, Hokama Heights Subdivision Addition #1, subject to recording a resolution with the State District Recorder's Office. 1999.

The lot is currently vacant with no development to the east. The attached site plan and backup documentation identify the size and location of the new absorption trench to serve the home. It also shows the location of the existing well and the 100' protective radius. A note on the plat for the subdivision restricts Lot 5 to a three bedroom home. We are proposing to place a biocycle septic tank, however, which requires only half the normal absorption area. We therefore request the permit be issued for the construction of a four bedroom system. Three testholes were placed on the lot during the subdivision phase of the project. All holes were nearly identical with percolation rates between 30 and 60 minutes per inch at the 7' to 8' level. No groundwater was noted during excavation nor was any found during the monitoring period. We are therefore proposing to construct a deep trench system with 6' effective depth. Total length will be 60' with the distribution piping at 3' below the existing ground surface. A biocycle recirculating septic tank will be placed with a pressure distribution system. The surface of the lot slopes from north to south at varying rates with some grades approaching 25%. The slope in the area of the proposed absorption trench is between 6 and 10% and is more than 50' from any slope in excess of 25%. Lot 5, Hokama Heights June 25, 1998 Page Two If the system is constructed as designed the following statements apply: 1. The system, if constructed as designed, will have no adverse impact on the wells in the area or those to be constructed in the future. 2. The system, if constructed as designed, will have no adverse impact on existing septic systems in the area or those to be constructed in the future. 3. The system, if constructed as designed, will have no adverse impact on reserved space, either surface or subsurface, on any lots located in the area. 4. The system, if constructed as designed, will have no adverse impact on drainage patterns in the area. The current drainage pattern w i I I be maintained. Sincerely, Michael E. Anderson, P.E.

A well and septic permit (SW980238) was issued by your department on 7/16/98. The permit for the proposed septic system was for a innovative `Siocycle" Unit with a drainfield designed by Anderson Engineering. We are proposing to have the permit revised to install a conventional septic system. It is our understanding that there is a special limitation on the plat of this subdivision limiting the number of bedrooms to three. Our clients are attempting to have this limitation removed. We propose to size the septic system for a 4 bedroom house and at the request of our clients, we also propose to install the alternate trench along with the primary trench. Comments regarding the revised propose design are as follows: 1. SOILS: Attached is copies of the soils logs performed by Anderson Engineering, Michael E. Anderson, P.E. on 3/8/94 & 3/9/94. As can be seen on the logs, both test holes have similar soils conditions of SM to SP/SM to SM/ML. Two percolation test were performed in each test hole between the depth of 7-8 feet. The percolation rates were 53 and 56 minutes/inch. No groundwater was encountered at the time of construction. 2. TRENCH DESIGN: a. Percolation Rate: 53 & 56 minutes/inch b. Allowable Application Rate: 0.45 gallons/day/ft2 c_ Number of Bedrooms: 4 d. Design Flow: 600 gallons per day e. Minimum Absorption Area: 1334 ft2 f. Total Depth: 12 feet (max.) g. Effective Depth: 8.5 feet h. Width: 3 feet i. Minimum Length: 80 feet j Effective absorption area = 1360 ft2 (>1334 ft2) Pte4l,r SLAj 96o2-38 3. SURFACE WATERS: There are no surface waters within 100 feet of the proposed upgrade. 4. TOPOGRAPHY: As can be seen on the attached topography site plan, the approximate slope in the area of the proposed trenches is a 10-15% grade. There is a slope greater than 25% approximately 70 feet downhill from TH#4. In short, there are no slope concerns. I am unaware of any adverse impacts this installation would have on adjacent wells or septic systems. If you have any questions, please contact me at 337-6179, or 244-9612.
