Home My WebLink AboutHANSEN SAND LAKE S-5480 TABLE OF CONTENTS INTRODUCTION SITE DESCRIPTION FIELD INVESTIGATION SUB-SURF?.CE CONDITIONS CONCLUSIONS AND RECOMMENDATIONS LOCATION MAPS TEST LOGS AND DATA INTRODUCTION This report is the result of field investigations conducted on 2uly 3, 1973, on properties in the Sand Lake area of Anchorage known as Hansen Sand Lake Addition, Lot 13. The area comprises about 1.96 acres. The purpose of the investigation was to determine feasibility of the proposed resident<al development. SITE" DESCRIPTION The property under investigation is in its natural state and fronts the South side of 74th Avenue, a gravel street. There is a home site on the West boundary and some development in adjacent areas within reason- able distance of all sides of the property. Most of the area is covered by dense'trees of birch and spruce. Good drainage exists to the North. "FIELD INVESTIGATION Soils investigation consisted of two test trenches dug with a Case 580 Backhoe. Visual inspection was.made and logged in this report. "SUBzSURFACE CONDITIONS The U. S. Geological Survey Bulletin 1093 defines soils in the area as Pre-Wisconsin pitted outwash. This is defined as deposited, horizontally stratified sand and gravel materials overlaying a ground moraine. They are located within defined areas between Spenard and Campbell Creek, boun.dgd by silt deposits and swamp deposits. Test trenches confirmed these findings, revealing very homogeneous brown fine sands representative of the area. No water or seepage was encountered. These sands border on frost susceptible material; however, no hydrometer tests were done to confirm this. Material was moist, non-cohesive, and non-plastic to the touch, presenting a clean appearance. CONCLUSIONS AND RECOMMENDATIONS We conclude that the area under investigation is suitable for the proposed residential development. On-site disposal of sewage is feas- ible; however, plans should be initiated to provide public sewer service to the property within a period of about five years from the date of development of private systems due to the fine-grained nature of these soils. Since the area is high ground and the soils homogeneous, perco- lation rates' should be adequate with a design factor of 125-150 square feet per bedroom. U. S. Geological Survey reports on the availability of ground water reveals confined deep aquifers from 200 through 400 feet in depth with moderate yields and poor, low permeability aquifers at shallower depths. Sand Lake School well'produces 50 gpm at 334 feet. Other wells in the shallow aquifer ~roduce from 3 through 10 gpm at 40 through 140 feet in depth. RespectfullY submitted, HEWITT V.

There is also a "Land Use Permit" issued by the Borough for a service station to be moved Onto the north side of this land and it is in the process of being moved at the present. You are proposing to zone this property R-1. I strongly ob- Ject to this. This property should be B-1. First, I had bought this shop at Tract B, Town and Country at the end of Cutty Sark. I checked with the subdivision covenants and they stated that this Tract B would be reserved for the shop. I started renovating the shop and spent $1,300.00 to McKinley Fence for posts and concrete before I was informed by Mr. Milligan, with GAAB planning staff, that I would have to remove the two story building. Foote's House Moving moved ~his building in the dead of winter at a cost of i$1~200o00~ this cost of $2,500.00 is money down the drain. 'This property abuts B-1 property and faces Jewell Lake Road and it isn't feasible to be zoned R-1 at the prevailing price of property in this area. Your urgent attention and fore-site would be most welcome be- fore zoning this business property R-1. Creater Anchorage Area Borough PLANNING DEPAttl M Yours very truly, SIMPSON CONTRACTING, INC. P.
