Performed by:_ GEOLOGIC SOIL INVESTIGATION OF BERNARD SUBDIVISION Located in Sec. 19, T 14 N, R 1 W, Seward Meridian on the Eagle River Report to: .Bernard Stewart P.O. Box 626 Eagle River, Alaska 99577 July, 1971 Prepared by: Hewitt V. Lounsbury & Associates 723 West 6th Avenue Anchorage, Alaska 99501 This report is the result of our field geologic and soil investigation conducted on July 15, 1971, on Bernard Subdivision, Eagle River; Legal Des- cription: Tracts contained in Section 19 of Township 14 North, Range 1 West, Seward Meridian. Bernard Subdivision is a newly proposed residential area being planned exclusive of public water or sewer utilities. Development of adequate san- itary facilities will be the responsibility of the individual property owners. The sewage disposal will consist of conventional septic tanks draining into a seepage pit and/or drain field. The water source will be from individually drilled and cased wells or community development of an already existing water well high on the property. The purpose of the investigation was to define in detail the soils con- ditions within the property and determine area requirements for proper sewer seepage in the particular soil found. Our investigation consisted of (1) a geologic review of the general area, (2) field reconaissance of slope and contour, and (3) exploratory trenching at selected representative sites. Page 1 Specific types and depths of soils are shown on enclosed trenching reports. The soils were found to be generally l'glacial till" with a 12 to 18 inch layer on organic matter of the surface and a 12 to 14 inch layer of clay - sand (of light and and dark bands) usually containing small Cobbles. Below these layers exist a moist brown unsorted mixture of sand, gravel and cobbles with'several 12 - 24 inch boulders, all mixed with traces of ~silt. The soil was found to be frozen in some areas at the six - foot depth line.~ CONCLUSION From information available we conclude that soil conditions are well suited to the proposed development and the percolation of seepages should present no unusual p~oblems,. The seepage area requirements for individual systems based on a 8 feet deep pit with 3 feet of cover will be 200 square feet per bedroom throughout the area of investigation. If normal precautions are taken while installing both water well and sewage disposal systems using proper spacing, no contam- ination on adjacent properties should result.

Such data as: (1) Water wells, location, design and regulation (2) Pollution of ground water prohibited (3) Development of public (commercial)water supplies may be found in'Chapter 2 (Sanitation Engineering) Sub-chapter 1 (Water Supply) Regulations and Guide of the Alaska Department of Health and Welfare, Branch of Environmental Health.

Sanitation Comments November 30, 1973 Page Two 24) 25) 26) 27) 28) 29) S 3257 Keno Hills Addition No. 4 Public sewer and water is not available. The soils conditions, the lot size, and the availability of adequate volumes of potable water in this area all substantiate the development of this addition at its present lot size and pattern. S 3255 Teri Subdivision, Tract A-1 - A-4 Public sewer and water is not available. Soils information and water avail- ability data have been supplied from Teri Subdivision to the immediate south. This information supplied some three to four months ago indicates that this area is suitable for development. At the present time, tile only possible development in this area would be the larger tract on '~he northeast euge of the subdivision. There is a note on the tract that the sl~laller half acre tract will not be developed at the present time. This case meets with our Department's approval. S 3240 Resubdivision, Bernard Subdivision, Tract B-1. Public sewer and water is not available· 'We have no comments at this time until the acreage is further split into lots at which time ~e will require the full submission of data. S 3236 Risu-Tonax Subdivision Public sewer and water are not available. We find, from review of the data submitted, that the lot sizes are adequate, the soils conditions are adequate for on-site sewage disposal and the water infon~a'Cion, supplied from t~e existing wells in the area, shows that there are adequate volumes of potable water to serve the lots in this subdivision. This case meets with our Uepartment's approval. S 3232 Skyhill Subdivision Public sewer and water are not available. The soils information supplied shows that the soils are adequate for on-site sewage disposal, the lot sizes are adequate to support on-site sewage disposal and individual wells in the area, to the immediate north and to the southwest snow that adequate volumes of potable water are available for ind~ividual home development. S 3245 Marion Bowen Subdivision Public sewer and water is not available. Lot size is adequate, the soils con- ditions are adequate for on-site sewage disposal and adequate volumes of water are available for domestic purposes on these lots.

The first group of cases, listed below are those which meet our approval because all lots are served by public sewer and water. 1) S 3224 2) S 3210 Papago Park Subdivision, Addition #2, Vacation and Resubdivision · Tieszen Subdivision Public sewer, and water available to five (5) lots but not to Tract A and Tract B. 3) S 3227 4) S 3214 Muldoon Heights Subdivision The Quad Subdivision 5) S 3215 6) S 3219 Central City Subdivision Lake Otis Commercial Subdivision 7) S 3213 Eastridge Subdivision, Addition #1 8) S 3221 Hamilton Park Subdivision OTHER CASES: 9) S 3225 Eklutna Heights Subdivision All lots served by public water. sewage disposal. Soils are adequate for On-site 10) S 3220 Bernard Su hall v~ _~ i on -~o comments. 11) S 3211 Rolling Hills Estates Subdivision This meets our approval with the note covering Lot 2A (over) Wayne Mabry DEQ' Comments September 4, 1973 Page Two ll) S 3168 Thompson Industrial Subdivision Public sewer and water is available for extension into these lots. We recommend the petitioner enter into a subdivision agreement to provide public sewer and water to all lots. 12) S 3178 C Street Industrial Subdivision, Lot 3 Block 1 Public sewer and water is available for extension into these lots. We recommend the petitioner enter into a subdivision agreement to provide public sewer and water to all lots. The cases listed below cannot be grouped: 13) S 3164 Lot lA, Block l, C Street Industrial Subdivision Public sewer is available for connection to this lot. provided by well. This case meets our approval. 14) S 3169 R/O/W BLM Lot 40 Hater can be No comment. S 3165 Tract E-2, Block 2, Bernard Subdivision We have no comment until the tracts are broken into lots. 16) S 3-66 Grey Subdivision We recommend postponement to allow the engineer time to submit the required data. Data lacking is: l) water availability data; 2) we question if the submitted soils logs show the seasonal high water table - the soils testing firm must indicate this on supple- mental data; 3) we must have locations o~ all sewer and water on surrounding lands that will affect placement of individual utilities on ti~ese lots; 4) we must have sewer and water layouts for each tot. 17) S 3170 Voyager Heights Subdivision We recommend postponing this case to allow the engineer time to collect more data ai~d discuss the data witi~ our ~epartment. We question if major parts of ti~is proposal are suitable for deYelop- ment at this tin'~. Our data shoves mos'~ of ~he area ha~ very ~oits, the souti~ern portions of the proposal are very steep an¢~ question the availability of water from individual :~ells.
