From the lake the property slopes up an 8% - 12% incline with mature maple and oak trees to a plateau where the residence is located. Soil Conditions — The Hennepin County soil survey mapped the area as the Lester Series. The Lester Series is the Minnesota state soil and is very common in Des Moines Lobe glacial till deposits of central Minnesota, specifically Wright and Hennepin Counties. A copy of the description for the Lester Series is included in Appendix A. The soil survey indicates the soils in the Lester Series are very deep, well drained loamy soils formed in glacial till. Six soil borings were completed in the area of the proposed and alternate drain field areas, see Figure 1. The soil borings closely matched the soil survey description of the Lester Series in the proposed drain field areas. The site was initially investigated in May 2003 with then City of Orono Septic Inspector Matt Bolterman. It was determined during the completion of the initial soil borings that there existed high chroma mottles in the soil profiles. The presence of these features was somewhat confusing because of the landscape position and the elevation above the lake elevation. It was agreed to by the owner, Mr. Bolterman, and MEI to install piezometers and a monitoring well to determine if the mottles (redoximorphic feature� were the result of an active fluctuating water table or are relict features. .: ,.� . ��:.�,y.'"§ The�eb`at�'over~activ�e versus relict redoximorphic features in higher landscape positions in the Des "��fYi�'�"�:obe �ili'�c�f western and south central Minnesota has continued for several years. The "tTriiversify of Minnesota h�s instal�ed.piezometers and monitoring wells on some sites to try and draw some conclusions on this debate. The USDA Natural Resource Conservation Service in their � description for Lester soils (attached) indicates these redoximorphic features are relict. Our own personal experience in these soils, including the monitoring for the past four years on the subject site and other similar sites, indicates that the presence of these features and their classification as active or relict is dependent on several factors however predominantly by landscape position. When 1 located in landscape positions where there is a large watershed uphill of the location being investigated, free water and saturated soils are observed following heavy precipitation events. In higher landscape positions where little uphill watershed exists the soils do not receive enough inflow to become saturated for long periods of time if at all, water will runoff the surface versus soaking into the sub soil. Soil borings indicate the site is underlain by high chroma loam, and clay loam soils to approximately 5.5 feet. The parent material for the area, high chroma loam soils with many threads of calcium carbonates (often misidentified as low chroma iron reductions), were found to the depth of the borings. Many gray sand coatings on ped faces, calcium carbonates, and reddish iron concretions (referred to as ochres in the geologic culture) were observed. These soil features are a result of the soil parent material not a fluctuating seasonal water table. The confirmation of these features being the result of the soil parent material not a fluctuating seasonal water table was evidenced through the monitoring of three piezometers and one monitoring well from — July 2003 — May 2007. In July 2003 three piezometers were installed at the locations shown on Figure 1 at depths of 66 inches, 38 inches, and 28 inches below the ground surface. These depths were selected based on the results of the soil boring indicating a soil texture, soil color, and/ar soil structure change at ar near these depths. The monitoring well was installed at a depth of 68 inches. The piezometers and monitoring well were installed using the installation instructions obtained from the Army Corps of Engineers. The piezometers and monitoring well were observed monthly from the month of installation through May 2008, excluded November — March. On several occasions the observations were made 1-3 days following a large precipitation event to obtain data during worst case scenarios. All of the observations made yielded the same results, no free water or saturated soils were observed. Soil percolation tests were performed at the locations shown on Figure 1. The results from the tests are in Appendix A. The results of the soil borings, groundwater monitoring, and percolation tests indicate that the site can support a standard subsurface drain field at the proposed area depicted on Figure 1. A soil sizing factor of 2.0 square feet per gallon per day has been selected. Sizing of Treatment S sy tem — The existing residence is a small two bedroom seasonal cabin without a well. To accommodate possible future construction the Onsite Wastewater System (OWS) will be designed to accommodate a three bedroom, Type II single family dwelling with an estimated daily flow from the residence of 300 gallons per day. Description of the Treatment Process— • Primary Treatment - Sewage is gravity discharged from the house to a septic tank. Natural biological activities taking place inside of the septic tank will separate solids and suspended particles. Solids are reduced to some extent through this process. • Final Treatment — Effluent is directed to a new 480 square foot drain field. As the effluent trickles down into the soil biochemical processes remove harmful viruses and bacteria. 2 Description of Treatment S sy tem — (See figures, design sheets, and data sheets for additional detail.) • Septic Tank — (2) 1,000 gallon fiberglass septic tanks. Install septic tank per manufacturer's recommendations. • Septic Tank Risers — 24" diameter heavy corrugated PVC pipe. A watertight seal must be created between top of tank and the each riser. • Septic Tank Riser Cover — 24" diameter fiberglass cover with gasket. Tank riser covers should include insulation. Do not bury riser cover. • Drain Field— Excavate the drain field trenches as depicted on Figure 2 when the soil is less than the plastic limit to prevent smearing and compacting. Installer is responsible for determining if the soil is below the plastic limit prior to excavation. Depth of excavation shall be 1.5-2 feet on the downhill - " side of trench, scarified and leveled. Place Quick4 High Capacity Infiltrator Gravelless Chambers in the trench bottom connected by gravity drop boxes. • Grading - Back fill with native soil, seed for cover, and mulch for erosion control ASAP after installation. Create positive drainage away from the septic tank and drain field, allow for soil settling. Do not allow charmeled runoff over the drain field; create drainage swales along the outer edges of the drain field to prevent excess runoff on the drain field. Limitations - Our investigation, layout, design, and recommendations are based on data submitted. If conditions considerably different from those described in this report are encountered, we must be notified. If proposed construction is changed, we must be notified to evaluate the effect of the changes on the wastewater system. Any changes to the design must be approved by the designer and will be assessed additional design costs. If changes are made to the design without the knowledge and approval of the designer the design shall be void. All construction is to be in accordance with the ISTS ' regulations. Pipe type and size, installation requirements, septic tank construction, and other specifications not depicted in our report are to conform to ISTS regulations. The installer of the system is to be licensed by the Minnesota Pollution Control Agency. I certify that this plan, document or report was prepared by me or under my direct supervision and that I am a duly licensed Professional Soil Scientist and Designer 1 under the laws of the State of Minnesota.
