Site Evaluation Report—Sharratt Qesrgn� Gompany Page 2 <br /> .•' Otto Jab No. 15-049t7 November 17, 2015 <br /> GENERAL INFORMATION: : <br /> This design is for a Type �, 5 bedroom home and is in aceordance with the Minnesata PaiWtion <br /> Gontrol Agency Standards and Local �rdinances. <br /> A seasonally high water table was evidenced at 12 inches of depth in Soil Boring 1: The slope <br /> is�bout$%o: <br /> AD neighboring welis are located more than 100 feet away fram the prt�posed treatment area.� <br /> NOTES: . <br /> Keep:alt heavy equipment off of the proposed treatment area before and after construction as <br /> much as possible. The treatment area shouid be marked off before construction. <br /> With proper installation and main#enance this system should fiave na problem in treating septic <br /> effluent effectively: It is recommended that#he septic tanks be pumped every 3 years. <br /> MOUNt7 SYSTEM: ' <br /> Flaw:5 bedroom- 150 gallon/day/bedroom 150 x 5= 750 gallons per day(GPD). <br /> 75Q GPD x 1.Q0= 750 square feet. <br /> 10 foot wide rock bed 75 feet long =750.square feet. <br /> CONSTRUCTIdN EQUIPMENT: ' <br /> A rubber:tired tractor may be used for plowing ar disking to prepare the soil surface, but in no <br /> case shall a n�bber-tired tractor be used after the surface preparation is completed. A crawler <br /> ar tract-type tractor sha[I be us�d for mound construction. <br /> SOlL S1IRFAGE PREPARATION: <br /> The discharge pipe from the pump to the mound 'area shail be installed prior to;soil surface <br /> preparation. The#rench excavated to install the disCharge pipe shall be c�refully backfilled and <br /> compacted ta prevenf seepage of efftuent. <br /> The total area selected for th� mound, including that under the dikes, shaA be roughened in <br /> order to thoroughly break up any existing sad layers and to pravide a suitable transition.zone <br /> between the original soil and sand layer of the mound. The area;shal! be raughened onlywhen <br /> the moisture content of the soil 8 inches below the surface is drier than the pla�tic limit. <br /> Surface preparation or roughening may be performed with a mald board plow, a disk plaw, or a <br /> back hoe using anly the teeth. Mold board plow furrows sh�D be at least 8 inches deep, shall be <br /> thrown up slope and shaN run perpendicular to the slape. There shall be no�ead fuRow under <br /> the mound. <br /> Disking may be used for surfac'e preparation as a substitute foc mold board plowing in soils <br /> having percolation rates faster than 15 minutes per inch (sandy ioam) in'the tap 8 incM depth. <br /> Back hoe teeth may be used ta roughen the sail su�face and break up the sod laye�, Care must <br /> be taken so as#o nat compact ar puddle deepe��ail layers: In no case shall any surface soil be <br /> excavated and removed from the area: <br /> Mound construction shall proceed irnmediately after surFace preparat�on is comple€ed. Euery <br /> effart should be taken to prevent rain#rom falling on the prepared soil surface. <br /> 9 West Qivision Street, Buffala, MN 5�313 • 763-882-4727 � Fax 763-682-3522 � www.aftcaassocia#es.com <br />
