The investigation was made solely along the cut banks of the newly constructed access road within the proposed subdivisiou. The findin~Is are as follows with soils classifications related to bedrooms: 1. Cut bank in old slide area Fragmented rock, loose ......... 100 s.f./ BR. 2. Cut bank (3') Fragmented rock with some silt, loose .... 150 s.f./BR. 3. Cut bank (10') Silty, sandy fragmented rock, - ........... 225 s.f./BR. 4.

Cut bank (9') Silty, frarlmented rock ...................... 200 s.f./BR. The general conclusion that can be drawn from this inspection is one of concern. The soils boom,se of their looseness will certainly provide the percltlatJon as reqdired; however, a certain a:nount of surfaco appearance downhill off each scepa7!c pit may occur if prudent judgcnient is not exercised in thc site selectiou and conatruction of ~'ach individual pit. Tho seepage pit site locations as shown on the accompanyin~ plat arc general iD ll~l:tlre and alterations in the exact placement may be required where rock outcroppinq< are encountered. Thc lots are certainly large enotu[h to allow location mUust:nents within each confining lot boundhrics.

SEWER FACILITY PLACEMENT Dear Rolf: The owner, Mr. Wallace, elected on his own accord to provide test holes to allow soil classifications in addition to the ones made from road construction cuts. All test holes show acceptable soils and no bedrock encountered. An occasional erratic boulder exists that One may relate to as bedrock but such is not the case. Reference to my letter of September 8, 1972, wherein I expressed concern is made at this time. That "concern" was in reference to locating seepage pits in the low areas or draws. The seepage pit layout that was previously submitted was a schematic in nature and one should exercise caution in following precise suggested locations. The adjustment, however, of a seepage pit location was not consid- ered determental since the lots were of such large sizes. I expect to see some major changes in the seepage pit locations by owners and/or builders when a detailed investigation is made and all members of the household are being satisfied. Let me bring to your attention at this time that the cleared area on lot'4, block 1 is from homestead clearing efforts and not that of snow slides as was mentioned during the Planning & Zoning meeting.
