Soils: Three soil pits were dug in the area where the wastewater system is being <br />proposed. The soils are developing from coliuvium and glacial outwash. The soils contain <br />a high percentage of rounded gravels and some angular cobbles. They are deep and <br />excessively well drained. <br /> <br />Test Pit #2 <br /> <br /> (}-5" <br /> 5-51" <br /> <br />51-64" <br /> <br />Very gravely loam; 10YR 3/3; slightly compacted; 35% <br />Very gravely loam; 7.5YR 3/4; mod., f'me, subangular blocky structure; <br />55% coarse fragments; angular and round gravels; abundant roots. <br />Large round gravels and sand; 10YR 4/3. <br /> <br />Test Pit #3 Like <br /> <br />Test Pit #5 <br /> <br /> 0-14" <br />14-31" <br />31-48" <br /> <br />Silt loam; 7.5YR 3/2; granular structure <br />Very gravely sand; 7.5YR 3/3; 70% coarse fragments <br />Sands; gravels, boulders <br /> <br />Note: Soil pits were closed after describing the profiles due to an upcoming wedding to <br />be held at Jawbone. New pits will be dug on the 25th of August. <br /> <br />Proposed <br /> Development: <br /> <br />Sewage Flows: <br /> <br />Suggested <br /> System: <br /> <br />Secondary <br /> Treatment: <br /> <br />A duplex with 4 bedrooms on each side. <br /> <br />Design Flow = 600 gpd. Average Flow is difficult to estimate <br />because the unit will be used seasonally. During the winter there <br />will be very little use. During the week ends in the summer, <br />the flows will be in the range of 400 gpd. There will be no <br />dishwashers or clothes washers. <br /> <br />Primary Treatment = 2000 gallon fiberglass dosing septic tank. <br /> <br />Bottomless sandfilter with 600 sqft. (Loaded at 1 gpd/ft2) <br />2 trenches, 5' wide by 120 feet long. <br /> <br />Contact People: <br /> <br />Scott Fogerty <br />Friends of Opal Creek <br /> <br />503-493-2894 <br />503-897-2921 <br /> <br />Zan Ewing and Lee Grimes of Marion County will visit the site on August 25, 1999 at 1:00 <br />PM. I will be there to meet George Atiyeh and Jan Houck at 12:00. Doug Macy will also <br />try to make the meeting. <br /> <br /> <br />
