Exceptional outcomes. July 15, 2016 Shawn Wischmeier 2851 Washta Bay Rd Excelsior, MN 55331 Subject: Individual Sewage Treatment System (ISTS) Design This is a revised version of a design submitted in May 2016. The revised design is for a four bedroom home instead of a three bedroom home as originally submitted. 1. Leaal Description - 540 Big Island; City of Orono; Hennepin County, Minnesota 2. Site Conditions - A three bedroom, Type II, approximately 2,000 square foot residential home is proposed. The exact footprint of the proposed home has not yet been determined; final tank location and length of pipe may change with the final installation. An approximately 15% slope exists at the proposed drain field location. The proposed home will be served by a new well that will be located outside the required 50 foot drainfield and tank isolation distances. 3. Soil Conditions - The Hennepin County Soil Survey was reviewed prior to our site visit; the soil survey indicates the site is underlain by glaciai till deposits. The soil profile description completed from the soil borings is found in Appendix A. The location of the soil tests are found on Figure 2. The site is suitable for a subsurface drain field. Seven years (2007-2014) of site-specific well and piezometer monitoring data indicate the site does not experience seasonal saturation within 66 icnhes of the surface (depth of monitoring well), even during record high water levels and record precipitation (May 2014). Observed soil mottling is due to calcium carbonates, iron concretions, or relict redoximorphic features and not due to seasonal soil saturation. See Appendix A for a Technical Memorandum submitted by Wenck to the City of Orono regarding Big Island soils and groundwater monitoring. Four percolation tests were conducted in the area of the proposed drain field. The most restrictive result was approximately 9 minutes per inch. Based on the soil profile descriptions and perc tests a loading rate of 0.45 gallons per day per square foot was selected. See Appendix B for soil information. 4. Sizinq of Treatment Svstem - The ISTS is designed for a four-bedroom Type II residence; the estimated daily flow for this residence is 375 gallons. Sink and toilet fixtures need to be monitored closely to ensure proper operation. A leaking faucet or toilet can more than dout�le the daily flow to the ISTS and cause hydraulic failure. 5. 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.

Ezceptional outcomes. • Final Treatment - Effluent is filtered through an effluent filter and pumped to a gravity fed drain field. As the effluent trickles down into the soil biochemical processes remove harmful viruses and bacteria. 6. Description of Treatment System - (See Figure 2 and design sheets in Appendix C for additional detail. Contractor can select equivalent products to those described below if they meet the requirements of local ordinance, MN Rules Chapter 7080, designer approval, and owner approval). • Septic Tank - Proposed: 1,500 gallon Infiltrator° IM-1530 septic tank. Inlet and outlet of the tanks must have rubber fittings to create watertight seals. Contractor to follow manufacturer installation and burial requirements. • Lift Tank - Proposed: 1,000 gallon Infiltrator° IM-1060 septic tank. Inlet and outlet of the tanks must have rubber fittings to create watertight seals. Contractor to follow manufacturer installation and burial requirements. Tank to include an effluent pump in a screened vault to deliver a minimum of 20 gallons per minute with a 20 foot head. Use two-inch Schedule 40 PVC for supply pipe from pump to the first drop box. • Septic/Lift Tank Risers - 24" diameter heavy corrugated PVC pipe. A watertight seal must be created between top of tank and the each riser using a tank to riser adapter and sealing the riser to the adapter with appropriate waterproofing agents. Top of riser should be 1" - 3" above finished grade. • Septic/Lift Tank Riser Cover - 24" diameter fiberglass cover with gasket and minimum 2" of insulation. Do not bury riser cover. • Drain Field - Excavate the drain field at the location depicted on Figure 2 and as staked on site. Contractor can vary location slightly based on field conditions to install trenches on contour. Install trenches shallow with a maximum depth of 24 inches. Each trench is 33 feet long (32 feet of chamber with a one-foot wide center positioned dropbox). Install seven trenches as shown on Figure 2 for a total area of 540 square feet. Total trench length is 222 feet, or 56 chambers. There is a large tree and a hole where a tree used to be that will conflict with trench number 3. It is likely this tree will need to be removed, the installer is to determine the appropriate action. • Install 45 Infiltrator°Quick4 Standard gravelless chambers. Effluent will be distributed through drop boxes. Install the chambers as recommended by the manufacturer. Cover the gravelless chambers with 12-18 inches of cover and slope away. Establish a vegetative cover over the drain field immediately. See Appendix D for tank and chamber manufacturer's specifications. 7. 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 or components are 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.

To: Roger Peitso, Building Official, City of Orono From: Peter Miller Professional Soil Scientist (42636) Advanced Designer/Inspector (2341) Date: March 8, 2016 Subject: 540 Big Island Purpose The subject property is a 3.2 acre lot on the southwest end of Big Island on Lake Minnetonka. The property is currently owned by Mr. Gabbriel Jabbour and is for sale. Mr. Shawn Wischmeier has expressed interest in the property and has requested this correspondence with the City of Orono with the ultimate goal to obtain an Individual Sewage Treatment System (ISTS) permit for a proposed cabin on the lot. Due to the time of year, it is not practical to visit the site with the City until spring conditions allow. This memo is intended to inform you as to the background, history, and research that has occurred on the subject site and on Big Island. Our intent would be to submit an ISTS design in spring- summer 2016 for approval and permitting. The goal of this memo is for you to concur with the determination that an in-ground ISTS is suitable for the site to give the potential buyer assurance that an ISTS permit can be issued in the future. Background Big Island is a series of kettle lakes connected by channels and streams, with an underlying soil parent material of glacial till. Big Island, like other islands on the lake, is a glacial deposit of calcareous loamy-clayey soil with undulating, moderate to steep, topography. The Hennepin County Soil Survey maps most of the upland portions of Big Island as Minnesota's state soil; the Lester series. Lester soils are very prevalent across central and southern Minnesota with a commonly distinguished olive brown color in the subsoil with a loam to clay loam texture. On Big Island it is common to see these soils in the summit, shoulder, and back slope landscape positions, with slopes ranging from 6%-20%. Lester soils in these upper landscape positions are typically classified as well drained; meaning they are dry, bright colored, and feature a depth to free water greater than 5 feet below the ground surface. What has confused ISTS practitioners over the years is the presence of features in the soil that appear to be contemporary redoximorphic features, i.e. signatures in the soil that make it look seasonally saturated. These include reddish iron concretions, grayish iron depletions, and whitish calcium carbonates threads. When looking at redoximorphic features in the soil it is important to look at the preponderance of evidence to determine if the features you are observing are indicators of Wenck Associates, Inc. � 7500 Olson Memorial Highway � Suite 300 � Golden Valley, MN 55427 Toll EreF 800-472-2232 ��1air� 763-252-6800 En�ail wenckmp@wenck.com �":%eb wenck.com . -�- Roger Peitso � Building Official WENCK City of Orono � ReSpOnslve parmer. Ezceptional outcomes. contemporary wetness. A Professional Soil Scientist (PSS) is similar to an archeologist in that we need to determine what was here thousands of years ago and why do we see what we see today. We weigh all available evidence to determine how the landscape formed, how the soil formed, and what factors (climate, relief, vegetation, organisms, geology/parent material, precipitation, run-on/off, etc.) contribute to the current morphological features observed in the soil. The Soil Conservation Service (now the Natural Resource Conservation Service) used PSS to conduct the National Cooperative Soil Survey. Soii classifications and descriptions are based on consideration of all the factors mentioned above, including contemporary versus historic hydrologic considerations. In previous versions of the Soil Survey the Lester series had the term "relict redoximorphic features" included within the series description. PSS who mapped these soils looked at all the evidence and determined that these glacial soils in upper landscape positions exhibited features that indicated wetness at some time in the past (thousands of years perhaps), but it is not contemporary. While ISTS practitioners receive training to interpret soil science to the best of their abilities, the economic realities of the industry do not allow for a deeper verification of what they see. When challenged, and with the potential to enter a lawsuit over a soil interpretation, it is not surprising an ISTS practitioner would be conservative in their interpretations. After pressure from the ISTS industry, because ISTS practitioners were incorrectly applying the relict tag to currently saturated soils as a "way out of a mound", the NRCS removed the term relict from series descriptions in Minnesota. Many soil series in other states (South and North Dakota for example) still maintain the relict description. Big Island We have been evaluating soils and ISTS suitability on Big Island from 2002-2016. At this same time we have been concurrently evaluating similar glacial soils across western Hennepin County, Carver County, Meeker County, McLeod County, and Wright County where similar glacial geology exists to Big Island. In the early 2000's we were making interpretations for ISTS suitability on Big Island for subsurface ISTS drain fields. At that time we were completing soil verifications with the City of Orono before soil verifications were required by rule. Then City of Orono ISTS Inspector Matt Bolterman visited as many as a dozen sites to witness the completion of soil borings for design, as well as installations. After Mr. Bolterman left, Willie Gibbs made visits to Big Island to review monitoring wells and piezometers installed on the island and to review soils. Mr. Gibbs visited the subject site at 540 Big Island around 2009. The third inspector we visited the island with was Loren Kohnen of Metro West Inspections in 2014. City of Orono records should have recorded these visits for the following properties: 540 Bi Island 510 Bi Island 150 Bi Island 440 Bi Island 210 Bi Island 140 Bi Island 450 Bi Island 190 Bi Island 120 Bi Island 620 Bi Island 180 Bi Island 130 Bi Island 470 Bi Island 170 Bi Island 460 Bi Island 560 Bi Island 160 Bi Island 4455 Ba side Road 2 7:\201S,lechnical M=mo Final D3081C.docx �� Roger Peitso � Building Official WENCK City of Orono � . . Responsive partner. Exceptional outcomes. Around the mid-2000's our ISTS work on Big Island was questioned because we disagreed with some ISTS practitioners' soil interpretations. In response, we decided to install piezometers and monitoring wells on the properties highlighted above. The first set of piezometers and wells were installed at 170 Big Island for the Palm family and monitored for three years. The results of the monitoring showed that the features in the soil were relict. Documentation was submitted to the City of Orono and an ISTS was permitted and installed. Subsequent to that investigation, additional piezometers and monitoring wells were installed at other properties in 2007-2008. Over 10 years of monitoring has occurred on Big Island. Concurrently, we were monitoring others sites in Hennepin County in similar soils at varying landscape positions. Here is what we have learned so far: Lester soils with slopes in excess of approximately 6% on summits, shoulders, and upper back slopes do not receive enough water (rain and run- on) to maintain saturation in the topsoil or subsoil for long enough durations to cause an anaerobic condition that could affect ISTS effluent treatment. When observing the Big Island sites at the wettest and highest water times of year (including May 18 and 22, 2014 when Lake Minnetonka approached the 100-year high water level), no free water was observed in any of the piezometers or monitoring wells. The soil texture, slope, and upper landscape positions of these sites shed water down slope and prolonged seasonal saturation does not occur. Investigation at 540 Big Island The property was first investigated in 2007 with the completion of soil borings in the central portion of the lot near the top of a rise. The top of the rise is a logical location for a cabin and the soil borings were completed in the general vicinity with the purpose of determining ISTS suitability. The soil parent material for the area features high chroma loam soils with threads of calcium carbonates (often misidentified as low chroma iron reductions) and reddish iron concretions. These features were observed on the soil borings at 540 Big Island. These soil features are a result of the soil parent material, and not a fluctuating seasonal water table. Saturated conditions were not observed in the soil borings, or in the three piezometers and one monitoring well installed in October 2007 and monitored through 2014, so an in-ground trench system is proposed. In conclusion, the site is suitable for a subsurface drain field. Seven years (2007-2014) of site-specific well and piezometer monitoring data indicate the site does not experience seasonal saturation within 6 feet of the surface, even during record high water levels and record precipitation (2014). Observed soil mottling is due to calcium carbonates and iron concretions, and not due to seasonal soil saturation. Any observed redoximorphic features should be considered relict, and not representative of current hydrologic conditions. 3 T:`�2015\Technical Memo_Flnal 030Si6.docx Appendix B Soil Information Soil Profile Description Date Completed: 4/20/2016 Test Pit# SB1 Completed By: Matthew Summers Equipment: Hand Auger Project Shawn Wischmeier Highest Known Water >60" Landscape Position <10°/o Shoulder Vegetation Oak-Maple-Basswood forest Mapped Soil Type L22C2 Lester loam, highly eroded Mapped Parent Material calcareous loamy till Horizon Bottom Depth (inches) Matrix Color Texture Structure/Consistence Redoximorphic Features Notes 9 10YR 2/1 clay loam 13 lOYR 3/2 clay loam 17 10YR 4/2 clay loam E horizon 23 lOYR 4/3 clay 10%7.SYR 5/6 medium,prominent Fe 2%2.5YR 4/6 iron nodules,abrupt 33 10YR 4/3 clay concentrations,relict boundary.
