SITE EVALUATION REPORT <br />FOR JOHN B.A. IDSTROM, II <br />IN LOTS 13 & 14, AUD. SUB. No- 229 <br />'ORONO, MINNESOTA <br />10-5-85 <br />F-.Q6� �t1 <br />On August 29-31, 1985 two proposed lots were tested for both primary and alter- <br />nate drainfield sites to determine their suitability for on -site drainfield sys- <br />tems. Testing was done in accordance with Individual On -Site Sewage Treatment <br />Cve+nee C+m..d...d.. /uer •n % <br />Lot 1, the north lot, had an average percolation rate of 7.7 minutes per inch <br />for the primary site(holes 1-4) and a rate of 10.4 minutes per inch for the <br />alternate site(holes 5-6). With the possibility of a moderately high seasonal <br />water table, shallow trench systems would be needed for both sites. <br />0000 <br />Lot 2, the south lot, had an average peroolation rate of 21.6 minutes per inch <br />on the primary site(holes 1-4) and 15.2 minutes per inch for the alternate <br />site(holes 5-6). Because of the high seasonal water table, shallow trench <br />systems would be needed for both sites with some fill required over the trench- <br />es or an interceptor draintile used to lower the water table. <br />Additional information follows.
