Box 240773 ANCHORAGE, AK 99524 522-7773 $22-6779 (FAX) April 9, 2004 Lang And Associates 11500 Daryl Avenue Anchorage, AK 99515 Subject; Cloud Nine Subdivision Section 12 Land Parcel Geotechnical Investigation and Septic System Feasibility Dear Reader: We originally completed the investigation of your parcel for subdivision into 4 lots and a tract. The report concerning that work was forwarded to you in July of 2002. Since that time you have reconfigured the subdivision into 6 lots. Our geotechnical investigation indicates six lots may be feasible with the use of the Advantex or other high technology septic systems currently in use in the Municipality. Problem areas on your parcel occur in the southwest corner where only 3.5' of soil was found above bedrock. The Municipal ordinance governing septic systems requires a minimum of 6' separation from bedrock. This can be achieved by elevating the absorption bed with coarse sand as long as a minimum of 2' of in situ material is available that is neither saturated nor impervious. In the southwest comer of your parcel as much as 4' of coarse sand may be required. We recommend further field study to determine if other acceptable areas for septic systems are available on the parcel. It is our opinion, however, that with the use of the Advantex Treatment System a septic system meeting the requirements of the Municipal ordinance could be constructed on each of the six lots. Some grading and site work may be required to insure all setback requirements are met. Sincerely, Michael E. Anderson, P.E. PAGE:1 o8j 2 \�Ar2 pmwIee1NM-Vmo n5+ Section 12 T1114R31N.

Huffman Road S 1 t,1 10 JUN 22003 Anchorage, AK 99515 Subject: Burnham Subdivision Section 12 Land Parcel Geotechnical Investigation and Septic System Feasibility Study Dear Joe: At your request we completed a geotechnical investigation and septic system feasibility study on a 40 -acre land parcel located just south of Paine Road in Bear Valley. Our directive was to locate suitable areas on the property to allow subdivision into 5 or 6 lots. Test holes were placed on each of the proposed lots for the construction of on site septic systems capable of meeting the requirements of the Municipal Ordinance for the treatment of domestic effluent from homes to be constructed in the subdivision. Thomas Enterprises of Anchorage between June 26 and June 28, 2002, completed the excavation work. A total of 15 test holes and 8 test pits were placed.. Test holes were dug as deep as possible or to bedrock utilizing a track mounted backhoe. Test pits were dug to bedrock and the materials encountered in the pits logged. A monitor tube was placed in each hole where appropriate. Percolation benches were then constructed at various depths in the holes, but primarily between 4' and 7' below the original ground surface. A percolation cavity was prepared to determine the absorptive characteristics of the soils encountered in the test holes. The cavity was presoaked in accordance with Municipal requirements and a percolation test performed. The results of the tests are included in the attached documentation. The underlying material encountered in the test holes varied throughout the site, but was primarily composed of well to poorly graded gravels with silt contents ranging from 5% to over 25%. The percolation rate of materials encountered also varied from less than 1 minute per inch to 30 minutes per inch in areas with higher silt contents. The majority of the tests, however, were between 1 and 5 minutes per inch. Groundwater was encountered in only 3 of the test holes. Water monitoring completed over the ensuing 14 -day period further indicated no groundwater except in the 3 holes. Burnham Subdivison• • Septic System Feasibility July 16, 2002 Page 2 of 2 The ground slopes throughout the subdivision are very steep, but test holes were placed in areas where a separation of at least 50' from any break in grade of 25% or greater could be attained. Grading will be required in most instances to meet the Municipal requirement of a 50' separation between a septic system and a 25% break in grade. An accurate topographic survey will be required by the Municipality to verify the surface slope at the location of the proposed septic systems. Bedrock was found in many of the test holes at varying depths. The Municipal ordinance governing septic systems requires a minimum of 6' separation between the bottom of the absorption system and bedrock. This can be achieved by mounding above the ground with coarse sand and placing the absorption system atop the sand. In the past, the Municipality has required the use of nitrate reducing septic systems in areas of shallow bedrock and steep slopes. These systems will probably be required on your development also. Although these systems are more expensive than standard gravity septic systems they require much smaller absorption beds and have an indefinite life span when properly maintained. The R-10 SL Zoning requires lots be a minimum of 7.5 acres when slopes on the property are greater than 30%. In addition, the lot must have a minimum of at least 300' in width. These requirements would allow a total of 4 lots on this property in the north south direction and a 10 -acre tract at the southern boundary. At this time we have been unable to find suitable septic system sites in the 10 -acre tract at the top of the parcel. Test holes were located in areas, which were assumed to be the primary location for the new septic systems. These locations are shown on the attached map, which define the area of the subsurface study. Please review the attached data and advise if you have any questions. A final report showing the reserve areas and location of the proposed wells to serve each lot will be required by the Municipality of Anchorage Development Services Department before approval will be given for the subdivision.
