Old Business VER VIEW ESTATES SUBDIVISION (subdivision) 160 acres; 126 lots; located in the Eagle- River area adjacent to Chugach State Park north of Highland Drive and south of Eagle River. ApprovaT subject to: T. Resolving lot size with the Planning Department and DEQ (minimum 1 1/4 acre lots). 2. Resolving the road pattern and drainage easements with the-PubTic. Works Department. 3. Resolve utility easements. 4 Providing additional soilsdata to the Department of Environ- mental Quality to be used in lot layout and size. 5. Creating one large tract of all the lots which abut the south fork of Eagle River. NOTE: After much discussion, the developer agreed to tract those lots abutting the- creek in order that the Borough can look into utilizing the Land Trust Fund concept to acquire the needed land along side- the creek. The developers intent is to give the -Borough approximately two years before he would be considering the development of that portion of his property.

Test pit locations were as located by Gross and within the area shown on the enclosed vicinity The ground surface in the subdivision area slopes down iil toward Eagle River to the north. The U.S.G.S.mapotiol. area indicates a single geologic unit of glacial Although no bedrock was encountered in any of the test pits, outcroppings of bedrock are apparent in road cuts in the general area at higher elevations. Thees encountered were sands or gravels overlain withsoil types of black organics. The sanspercolation grab about one Pert (y1) give good rates.

Fork, the principal tributary of Eale River. Ea;_41e River valley is a glacially scoured trough which has been partially refilled with glacial till, granular glacial outwash, silty lake sediments and coarse sand and gravel alluvium. The glacial till and silty lake sediments were deposited during repeated advances of. ancient Eagle Glacier. Outwash was deposited during the final retreat of Eagle Glacier, while alluvium has been deposited in the modern channel of Eagle River and in a fan at the mouth of South Fork. TOPOGRAPHY Land Forms The land forms of River View Estates are the complex result of the deposition and subsequent erosion of sand and gravel by meltwaters released during the final retreat of Eagie_Glacier. This "glacial alluvium" (Zenone, et. al., 1974) occurs in small hills and terraces that trend roughly parallel to Eagle River valley. The terraces are crossed and deeply notched by the channel of South Fork along the east side of the subdivision. Slo es The terraced alluvium soils support nearly flat to moderately gentle slopes (less than 5% to 15%). The soils exhibit generally high stability and there is little likelihood of significant downslope movement. However, in response to severe earthquake shocks small areas with steep slopes could be subject to movement and should be avoided when siting foundations. SOILS Virtually all of the subdivision is underlain by well graded alluvial sand and gravel soils deposited as the glacier front receded. Individual layers of sand and gravel vary greatly in thickness and lateral extent and cannot be correlated with confidence between test pits and expo- sures. However, the general character of the soils (well J graded sand and gravel with common cobbles and boulders) is consistent throughout the mapped area. Thin layers of silty sand or gravel were occassionally encountered (as in Test Pits 4 and 5). These probably represent "overbank" deposits that settled out beyond the main meltwater channels. Dense silty gravels indicative of ice -contact glacial deposition (such as moraines) were not encountered in any of the exploratory test pits. Thin (Less than 3 feet thick) peat lenses occur at the surface locally in narrow abandoned drainage channels (as in Test Pit 8). GROUNDWATER The depth of groundwater varies from place to place within the subdivision. Along the northern edge of the area the terraces and low hills consist of well drained, clean sand and gravelyand water levels are at least 11 feet below ground. Shallower water levels are found along the axes of abandoned channels (as shown on Geologic Section 1). The exceptionally permeable well graded gravels found in all areas of relatively shallow water will allow the construction of sanitary drain fields in the upper few feet of soil, constrained only by proper protection from freezing and careful identification of groundwater levels at the exact site of proposed installations. Above an elevation of. 620 feet, water levels are all below 12 feet below ground level except in Test Pit 8. This pit was dug in the center of a narrow swale to test for the presence of organic soils. The pit encountered 4 feet of compressible soils with water 5 feet below ground. Pit 8A was then dug 60 feet to the north of Test Pit 8 and found no water to its total depth of 111- feet below ground as shown on Geologic Section 3. Groundwater drains to the north towards the floodplain of Eagle River. Unconfined water levels along the north edge GARY PLAYER VENTURES of the northernmost tier of lots will probably be lower than shorn in the test pits excavated along the southern boundaries of those lots because of the northward gradient of the water table. Lots adjacent to the bluff of South Fork will similarly have their lowest water levels nearest the creek. SUM•ii4ARY Soils throughout the River View Estates subdivision are well graded sand and gravel deposited and subsequently eroded by meltwater streams from ancestral Eagle Glaciers Groundwater levels are acceptable .for the construction of onsite sanitary drain fields, although careful determination of the most suitable disposal site will be necessary on the northernmost tier of lots.

SURVEYOR'S CERTIFICATE N O O. 4 Riverview Subdivision PRELIMINARY SOILS AND FOUNDATION INVESTIGATION Riverview Suhdivision Eagle River Area Report To John Gross Construction Company Anchorage Alaska Prepared By Jim Brennan,Geologist Anchorage,Alaska March 1974 March 28,1974 Jim firennan, Geol og I st 4003 Minnesota fir. Apt.11 Anchorage,A1aska99503 Phone- 277-4900 Gross Construction Company 5501 Kcnnyhi l 1 Drive Anchorage, Alaska Attention: 'qtr. John Gross RE: Prliminary Report of Soils and Foundation Investigation - Riverview Subdivisi.on,located in the Eagle River Area John; This letter presents the results of an Investigation of geological and soils conditions of the Riverview Subdivision.Of primary interest was determination of the subsoils,rates of seepage,and various stratigraph units in the arca. A reonnaissance of the area was followed by test borings.These borings were made with a nodwell mounted B-61 mobil drill utilizing, 6 -inch solid flight auger. Four borings were drilled adjacent to the access road along the south (uphill) boundary of the subdivision. The soils encountered were examined by myself and visually classified. Soils gradings of samples obtained were rur. by R&M Engineering of Anchorage. GEOLOGY AND SITE CONDITIONS The ground surface in the area of the subdivision slopes downhill towards Eagle River to the North.Therc are numerous small terraces on this Southside of the Eagle River Valley. The auger borings to date vegetation,slope visible road cuts in the, arca,and the U.S.G.S. Generalized map of the Eagle River -Birchwood area (Open file 19"1) all point towards the subdivision being located within a single geologic unit of glacial till (silty gravelly sand and - silty sandy gravel) The origin of this till is probably ground moraines NctaSediment) bedrock is exposed along the sides of the South Fork of, Eagle River in the Eastern portion of the subdivision. Vegetation consists mainly of Birch to 6"+ diameter with some light- brush and Spruce.The organic soils appeared to be 1.5 to 2 feet in thickness. Surface drainage is excellent due to the moderately steep slope down towards Eagle River. SUBSURFACE MATERIALS AND CONDITIONS The four borings penetrated 13 to 16 feet.The materials penetrated were typical glacial till varying from silty gravelly sand to silty - sandy gravels with varying amounts of silt, cobbles, and boulders. The subsoils were found to be very dense.?lost of these subsoils encountered can classified (GM)on the anified system. At the time of the borings the moisture content of the subsoils was low.No ground water was encountered at this time,and no seepages or icing was noted on the hillside. Due to the inherent nature of unsorted glacial deposits,however,it is difficult to substantiate general conclusions about the entire, arca.The data presented here should however aid in determining appropriate developement patterns.For any particular site more detailed subsurface geologic Investigations may he required. Wintry conditions precluded areas of difficult access in March and therefore were not drilled. CONCLUSIONS AND RECOMMENDATIONS: ON SITE? SEWAGE DISPOSAL The Investigation to date appears to indicate that on-site sewage - disposal is possible.Seepage areas required per bedroom are in the 225-250 square feet range. WATER SUPPLY It is anticipated that the greatest potential for an Aquifer is the connect between the glacial soils and bedrock.This may be as deep as150' FOUNDATION CONDITIONS The foundation soils encountered are extremely competent,Footings, should be placed below the depth of the seasonal frost penetration, because of the silt content.
