ANDERSON ENGINEERING P.O. BOX 240773 ANCHORAGE, AK 99524 522-7773 677-7766 (FAX) MEMORANDUM DATE: May 16,2011 TO: Jeff Poet FROM: Mike Anderson, P.E. SUBJECT: Lot 16A, Block 3H, Rabbit Creek Heights Subdivision Certificate of On Site System Approval (COSA) The following modifications have been made in accordance with your review comments for the conditional COSA for the subject property: 1. The curtain drain was not installed. No groundwater or runoff water was encountered during October of last year. A drainage swale was completed along the eastern property line prior to the construction of the absorption bed. This swale may be effective in controlling the surface water which may affect the new bed. We intend to monitor the area during breakup of this year. It surface water becomes a problem, the drain will be installed. The final approval for the COSA will not be requested until after breakup. At that time we will know whether the curtain drain is necessary. 2. The percolation test was required because the alternate site was not totally within the 30' radius of a percolation test. The final as built shows both the primary and alternate sites within the 30' radii of the percolation tests. No further testing is therefore necessary. All percolation tests completed during construction however indicate the soil is consistent throughout the absorption area. 3. The buyer, Mr. Gunnar Benson, completed the Maintenance Agreement during the permitting phase of the project. 4. The waiver to surface water request has been modified to show the current status the absorption bed. It is attached to this memo. Municipality of Anchorage P.O.

The new absorption bed was constructed in the southeast corner of the lot which is located directly north of a flowing ditch on the south side of Diane Drive. The southwest corner of the new absorption bed site is 54' from the ditch. A waiver is therefore necessary from the 100' setback required by ordinance. An Advantex Treatment System was recently constructed on the lot which provides additional treatment to the septic effluent. In addition, the surface drainage path is away from the ditch at a 7% grade. If the system should ever overflow the effluent would follow the natural drainage path away from the ditch. The elevation of the ditch is currently higher than the existing ground in the area of the new absorption bed. The soils underlying the absorption bed are very good to excellent. The likelihood of a failed septic system and overflowing effluent are very Iow. Should the situation occur the flow is to the northwest away from the surface water. We therefore recommend the waiver be issued allowing the septic system to remain in its constructed location at 54' from the surface drainage. Sincerely, Michael E. Anderson, P.E.

We are therefore requesting a permit be issued for a well and septic system to serve the new home. The available area for the septic system is limited by the presence of ground water close to the surface which make it difficult to place a conventional septic system. We therefore propose to place an Advantex Treatment System on the lot to provide the most effective treatment of the septic effluent prior to discharge into the surrounding soil strata. The location of the absorption system is shown on the attached Site Plan. A subdrain will also be placed to control surface and subsurface drainage in the area of the new absorption bed. Drainage patterns are also shown on the plan and will be modified somewhat as a result of the proposed construction. The ditch on the south side of Diane Drive flows nearly year round. A waiver request is attached to decrease the separation distance from the ditch to the absorption bed to 72'. Two test holes were placed on the lot by Watkins Engineering in November of 2004. A third test hole was recently placed in the area of the Watkins Test Hole No. 2. Ground water was found at a depth of 4' below the surface. The percolation rate in the materials encountered was 9 minutes per inch as opposed to 4 minutes per inch on the Watkins test. Our design provides for the bottom of the absorption bed to be at 2.5' above the ground surface. We are therefore proposing to place a three-bedroom Advantex Treatment System. The absorption bed will be 10' long x 15' wide for a total of 150 square feet of absorption area. The distribution line in the trench will be placed at 3.5' above the existing ground level. 2' of fill and 2" of insulation will be placed above the bed and 4' over the septic tank to meet Municipal Code and prevent freezing. The side slopes of the mound will be at 4:1 and extensive landscaping and fill will be reqUired to insure positive drainage away from the finished mound. Lot 16A, Block 3H, Rabbit Creek Heights Subdivision September 4, 2010 Page Two The ground surface of the lot slopes from the southeast to the northwest at a 7% slope. The bed will be constructed parallel with the contours of the slope as much as possible in conformance with Municipal requirements. All components of the new septic system will be constructed a minimum of 100' from the well proposed for this lot. No conflicts exist between the proposed well and septic system and those in the area. If the system is constructed in accordance with our design the following statements apply: 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. 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. The system, if constructed as designed, will have no adverse impact on reserve space, either surface or subsurface, on any lots located in the area. The system, if constructed as designed, will have no adverse impact on drainage patterns in the area. The current drainage pattern will be maintained. Sincerely, Michael E. Anderson, P.E. Attachments ANDERSON ENGINEERING P.O. BOX 240773 ANCHORAGE, AK 99524 522-7773 677-7766 (FAX) MEMORANDUM DATE: September 16, 2010 TO: Deb Wockenfuss FROM: Mike Anderson, P.E. SUBJECT: Lot 16A, Block 3H, Rabbit Creek Heights Subdivision Well and Septic System Construction Permit No. OSP101189 We reviewed your comments and offer the following response: 1. We measured the water levels in the monitor tubes yesterday, September 15, 2010, and found the water level in our Test Hole No. 3 at nearly 7'. Cindy Ellis' Test Hole No. 2 was at 4'. We found more than 2' of native unsaturated soil and invite your inspection to verify the levels. The previous summer has been much wetter than past years and the water table is probably higher now than typically found at this time of year. In addition, a ditch was installed in the recent past along the east property line which may be assisting in lowering the water table. The ditch is currently dry, but redirects surface runoff to the north and away from the test hole area. We have revised our Site Plan to utilize the ditch for the new subdrain planned for the lot. We therefore request that our measurements be used for the evaluation of the septic system design and issuance of the permit. 2. The calculations have been corrected on the soils log. The percolation rate changes by slightly more than a minute and is actually less conservative than the rate shown. 3. We are unsure of Cindy Ellis' water monitoring and prefer to rely on our data. As previously mentioned the past summer has been much wetter than the summer the test holes were placed. The water table today should therefore be higher than the year Cindy Ellis performed her monitoring. 4. The maintenance agreement will be forwarded directly by Spinell Homes. 5. We have modified the Site Plan somewhat based on our last field inspection. The modification resulted in moving the proposed absorption bed closer to the open ditch to the south. The request for modification to surface water has been change to 60'.
