U TO: Jeanne A. Mabusth, Zoning Administrator FROM: Michael P. Gaffron, On Site Manager DATE: June 15, 1983 � SUBJECT: Proposed Subdivision for Willow Properties, Gary Peterson - Soils and Site Investigation , Review ' I I have reviewed the ten proposed lots and wish to make the � following comments: Based on the Hennepin County Soil Survey, soils on this property include Lester loams and clay loams, Hayden loams, Hamel loams and LeSeur loams, as well as a good deal of marsh. Tested sites are located on the higher, better-drained soils. Some areas of sandy soil were reported on the most easterly lots. Based on the soils and water table data submitted, shallow trench or standard trench systems appear suitable for all lots. Following is a summary of the soils data for each site: Lot 1 Block 1 - Percolation Rate Average 22 MPI both sites - Primary site - slope 50 - mottling at 3 . 5' - water table at 3 .5 ' - modified shallow trench system* Maxi.mum Trench Depth 6" into original soil - Alternate site - slope 8� - mottling at 4 . 0 ' Water table at 4 .9 ' - shallow trench system - maximum � trench depth 12" into original soil Lot 2 Block 1 - Percolation Rate Average 18 MPI both sites - Prim�.ry site - slope 70 - mottling at 4 . 2 ' , 5 .0 ' - water table at 4 .5' , 5• 5 ' - shallow trenches - Maximum Trench Depth 14" into original soil. - Alt�rnate site - slope 8� - mottling at 3. 3' - water table at 3 .3 ' - modified shallow trenches* - maximum trench depth 4" into original soil Lot 3 Block 1 - Percolation Rate Average 23 MPI both sites - Primary site - slope 10� - mottling at 4 .0 ' , 4 .5 ' - water table at 4 .0 ' , 5.5' - shallow trenches - maximum trench depth 12" into original soil - Alternate site - slope 8� - mottling at 3 . 5 ' - water table at 3 .6 ' - modified shallow trenches*- Maximum Jeanne A.

Mabusth June 15, 1983 page 3 table at 4 . 5 ' , 5. 3' - shallow trenches - maximum trench depth� l8" into original soil - Alternate site - slope 60 - mottled at 3. 8 ' , water table at 3.8 ' - modified shallow trenches* - maximum � trench depth 10" into original soil i Lot 4 Block 2 Percolation Rate Average 14 MPI both sites ' - Primary site - slope 7� - mottling at 4 .4 ' , 5.5 ' - water table at 4 .4 ' , 5.6 ' - shallow trenches - maximum ; trench depth 17" into original soil � - Alternate site - slope 50 - mottling at 4 .0 ' - water table at 6 .4 ' - shallow trenches - maximum trench depth 12" into original soil . *Modif�ed Shallow Trenches - where water table or mottling is between 3 .0 ' and 4 .0 ' below the surface, a standard 12" rock depth (6" under pipe, 2" over) must be used in conjunction with an appropriate depth of fill material to retain a 3.0 ' separation between the bottom of trenches and the water table or mottling. Fill should consist of material classified as loamy sand (USDA classification) . The original soil must be dryer than the plastic limit before placing fill . The original surface must be scarif ied or disced to break up tlie surface vegetation mat. The loamy sand fill must be placed over the entire area so that no trench will be located less than 10 ' from the edge of the fill . The depth of fill required will depend on the allowable depth of excavation into original soil based on . the water table or mottling. I recommend that the subdivision be approved as proposed. The developer should be warned to keep all traff ic, fill excavation, etc. awa� from the tested drainf ield sites. In some cases where road construction will be near the tested sites, extra caution must be taken.

On P.ay 4-30, 1963 six percolation holes were tested c,n each of 10 lots and 3 soil borings taken on each lot as well in accordance with the provisions of Individual Sewage Sys- te:n Treatment� Standards (WPC-40) adopted in 19?8 by the N:inn- esotd Fallution Control tigency. In addition, other soil bor- ings were taken in lower areas to determine the possibility of obtaining more than 10 Iots but water tables were found to be verg high and the soils were fcund to be very slotirly �ermeable. �ccarding to the soils radps and the information we found in the field, tne higher areas had very good so�ls for drainfields while the lower areas and swales had extremely poor soils �or drainfields . Thus, we tended to stick to the ��i.gher �reas while still leaving room for ample building sites , uowever, ance houses are proposed to ��e constructFd it :riighL be desired to shii t some of the drainfiel3 are�.s .

This is a design approval form which must accompany the site plan. A permit must be issued to a licensed septic contractor prior to installation. A list of currently licensed septic contractors is enclosed. NOTICE TO INSTALLERS: Any changes to the approved plans and specs must have prior approval of the Inspector (473-7357). Call for inspections 24 hours in advance. ALL DRAINFIELD AREAS MUST BE FENCED OFF prior to building site excavation and fencing must remain in place until final site grading. Approval to pour footings will not be granted until the Inspections Depaztment has verified that primary and alternate sites are adequately protected. NO VEHICULAR TRAFFIC OF ANY KIND(cars, trucks, earth moving equipment, etc.) is allowed within 20' of tested drainfield sites either before or after system construction. Compaction of these areas could render them unusable prohibiting the timely completion and or limiting the long term use of the property. A site copy will be available at the City Offices for the septic contractor. CITY OF RON By Step n c , On site ystems Manager � � T'ELEPHONE-973-7357�FAX-473-p510 S"P TESTING� ��C. Steven B.

Co., MN This on-Site Sewage Treatment System is Designed for a Type 1, five bedroom home designed in accordance with the Minnesota Pollution Control Agency Chapter 7080 and local ordinances. The soils on this site are SCS soils mapped - LtB - Lesueur loam. The seasonally saturated soils were located at 20"to 28" (mottled soil). Due to the seasonally saturated soils, a Pressurized Mound System will need to be installed to treat septic effluent. The bottom of the treatment area must be located at least 3' above the saturated soils. The soils at a depth of 12" have a percolation rate averaging 5.6 mpi. A pumping chamber will need to be installed to lift the effluent to the treatment area. The power supply and switches must be located outside the manhole and pumping chamber in a weather proof enclosure. A waming device must be installed with a light and sound device, this is in case of a pump failure. The manifold and supply line pipe must have back drainage to the pumping chamber. The distribution pipes shall have their ends capped. Be sure the rock and sand fill material are clean. The sod layer below the entire mounded area must be tumed over, just break up the sod, be sure not to over work. All neighboring wells are located greater than 100' away from the proposed treatment area. 1 • t Keep all heavy equipment off of the proposed treatment area before and after construction. The treatment area should be marked off before construction. This Design is not valid &the system wiil need to be relocated if failure to protect the areas proposed for On-Site Sewage Treatment occurs. With proper installation and maintenance, this system should have no problem in treating septic effluent effectively. Nothing other than gray water(laundry, showers, etc.) human waste &toilet tissue � should be disposed of into the septic tanks. Garbage disposals are not recommended, due to adding more solids &fine solids passing through to the system. Excessive amounts of soaps, cleaning agents 8� chlorine agents may kill the bacteria needed to treat septic effluent. Additives are not recommended. Recommend to pump & clean your tanks through the manhole by a certified pumper every 2 years. Check with your pumper to set up a schedule. Steven B.

Co., MN This letter is in regard with the proposed future On-Site Sewage Treatment System area for this lot. �� The future expansion site has been traveled on by a skid loader. Soil Probing indicated � the soils have been compacted 2"to 6" deep. The compaction is not severe but cannot � be tested at this sha(low of depth. In reviewing the site with the city Inspe�tor, Steve Weckman, I would recommend the site be prepared at the same time as the proposed system is being installed by ripping or tuming over the soil approximately 8" deep, not deeper than the topsoil (loam soil). Due to this site being disturbed, there is no guarantee how well a system will iunction on this site. <�>�� . Steven B. Schirmers ��` � 2 ���� � TEL No .
