MN 55044 <br /> <br />Dear Neal: <br /> <br />As requested, Eco Systems Engineering comple~ 10 soil borings on lots located <br />within Preserve Estates. located in the SW ~ Sec. 23. T. 33 N.. R 26 W. of <br />Sherbmne County.}.iN. The borings were completed on September 1. 1999, and <br />their locations have been staked and flagged. The borings were done to determine <br />what type of individual sewage treatment system can be placed in the proposed <br />treatment system sites on each lot The soil boring logs. soil survey information, and <br />approximate locations of the borings are enclosed. <br /> <br />. <br /> <br />Please keep in mind additional soil borings and pere tests must be conducted within <br />the actual drain field sites once the homes have been staked. Pending these final site <br />locations, the results of these additional borings may indicate a different type of <br />septic system than outlined below. <br /> <br />The Sherburne County soil survey was also reviewed prior to our visit, and our <br />findings closely correspond with the existing mapping ofEckvoll, Stonelake-Nebish, <br />and Beltrami soils on the site. <br /> <br />Block 2, LOtslOaJidll (Soil Borings #01. #02); Block 1, Lots.7and.8 (Borings #06. <br />#07); and Block 3; LOt 4 (Soil Boring If 10) would require mound septic systems. The <br />depth to seasonal high water table on these lots ranges from 12" to 48" :from the soil <br />surface. A 3 bedroom home (2 bedrooms + finished basement) will require <br />approximately 2,800 sq. ft. of area each for the primary and alternate drain field sites; <br />a 4 bedroom home (3 bedrooms + finished basement) win require approximately <br />3.400 sq. ft. for each drain field site. <br /> <br />. <br /> <br />Block 2, Lots 7, 8, and 9 (Soil Borings #05. #04, #03), Block 1, Lot 9. (Boring #08), <br />and Block 2, LorI (Soil Boring #09) would support in-ground trench septic systems. <br />The depth to seasonal high water table on these lots ranges from 54" to not observed <br />within 62" from the soil surface. A 3 bedroom home on these lots will requite <br />approximately 470 to 625 sq. ft. of area each for the prima1y and alternate sites; a 4 <br />bedroom home will require approximately 630 to 830 sq. ft. of area. <br />
