I.,~,. ,o E ,-:~ 1982 RECEIVED Soils Investigation Lot 6A, Barnhill Subdivision, Anchorage, Alaska Dear Mr. Laird, This letter presents the results of the soils investigation that we performed at your request on Lot 6A, Barnhill Subdivi- sion. This property is located to the northwest of Dimond Boule- yard in the 6700 block. On May 13, lg82, 'we drilled a test boring to a depth of 20 feet at the location directed by Mr. John Laird. The drilling was performed by Mr. John Graham, of our staff, using our Bombardier-mounted Arctic Gas Auger. Mr. Pete Chalich, Geological Engineer on our staff, logged the boring and obtained sampl es. This work was requested to be performed to the minimum standards of the Department of Health and Environmental Protec- tion (DHEP). These standards include the drilling of a soils boring to a depth of 20 feet and the visual classification of the soil strata encountered by a field technician. In soils which are visually classified to include more than 6% silt, (soil finer than the #200 screen size), a percolation test is required to be performed in the area most likely to be developed for the absorp- tion system. Due to the clean nature of the soils observed from 7.0 to 20 feet, no percolation test was performed. The Soils Log and Boring Location Sketch are presented on the standard DHEP form, Plate 1. As a check to our visual classifications, a sieve analysis was performed on a sample from a depth of 7.5 feet. The results of the sieve analysis are presented as Plate 2. All soils were visually classified in the field according to the Unified Soils Classification System presented on Plate 3 and the Textural Classification System presented on Plate 4. Per- forated 1-1/2 inch nominal standpipe was placed in the deep boring to allow for observation of free water level after drill- ing. However, the boring sloughed below 13 feet, so no after- drilling observations could be performed below that depth. We were requested to perform this investigation to the minimum standards required by the Department of Health and En- vironmental Protection. It should be noted that in accordance with these standards, the classifications of the soils are visual and performed by a soils technician. These classifications are subject to change. Only the visual classification of the sample obtained from 7.5 feet has been verified by laboratory analyses. This work was performed for the sole purpose of preliminary evaluation by the Department of Health and Environmental Protec- tion of the suitability of on-site sewer system development. Any extrapolation of this data for other purposes is not within the intent of the investigation or requested services. We trust the foregoing is sufficient for your immediate needs and is compre- hensive within its limited scope. If questions arise or if we can be of any further service, please feel free to call.

The original concept for the configuration of lots was conceived back in 1975. The soils map shows where the soils holes are located. There will be an additional hole drilled for test purposes on lot 6. This subdivision is a subdivision of Tract b and Lots I and 2 Barnhill Subdivision into six lo~s. The proposed area is planned exclusive of public water and sanitary sewer utilities for the present. ~evelopme~t of adequate sanitary facilities will be the responsibility of the ~ndividual property owners. The septage disposal will consist of conventional septic tanks draining into a seepage pit and/or drain field. Drawings extracted from the Department of Health and Enviornmental Protection, Municipality of Anchorage, have been included as a part of this report for pictorial ourDoses of the septic systems required. Water source will be from individually drilled wells. The purpose of this report is to define the soils condi'tions wi~thin the property and determine the area requirements for proper sewerage seepage, in that particular soil. SITE DESCRIPTION This subdivision is located within the Municipality of Anchorage along Dimond Blvd west of Jewel Lake Blvd. and west of the gravel pits on the west end of Dimond Blvd. The land is quite hilly with abrupt slopes in places. It is well wooded with large spruce and birch trees. Specific drainage patterns would be hard to trace for the time being mainly because of the disruption in the drainage to the east and the configuration of the hills and dells of the whole area. SUB-SURFACE SOILS AND CONDITIONS Because this engineer did not do the specific soils work but only compiled the information into a presentable form, the §eneral sub-surface information is given herein from analysis of 'the information gathered. Generallly the area has about 1.5 feet of overburden and rootmat covering silty sandy gravels of a looSe nature, or just plain silty sands. 6oncl usions The percolation tests performed on the soils are self explainator.y fol~ the most part. The soils are somewhat loose in nature and are receptive to sewerage disposal. Based on the information obtained in these test holes, it is felt that this subdivision is quite suitable for single family units. It is felt that the soils conditions encountered do not preclude the utilization of septic tanks and soils absorption systems for residential use. James K. Dowling P.E.

Harch 2, 1978 File No.: PB3 Mr. John Laird Subject: Soils and Lot size - Barnhill Subdivision · Tract B, Lot 2 (approximately 6 acres) Dear Mr. Laird:' ' .m. Re-e~a'luation of the Subject property indicates it cannot be developed at the current density it is zoned (R-lA). This is because public sewer and water are not available to serve'the property and development must rely on private wells and sewer systems. The property could be subdivided into 1.25 to 1.50 acre lots using private wells ~nd sewer systems to serve single family .dwellings. This is the same development plan we came up with approximately 2 years ago when you submitted a proposal to subdivide this property. Sincerely, ~ro~m~21 Engineering JWL:lmp
