Mabusth, Zoning A ministrator FROM: Michael P . Gaffron, Sept!�c ystems Inspector DATE : April 17 , 1984 SUBJECT: #804 - Painters Creek (Ski- onka) Bayside Road - Subdivision - Soil Testing Review The additional testing required on Lot 9 as been completed and a report has been submitted for City review. The ots which required additional work have been reevaluated and this infor ation is now on file . I met with the site evaluator in early March an I am comfortable with his interpretations of the soil borings, whic I had earlier questioned. I would like to make the following comme�ts Lot 1 (Sites 9A & 9B) - Slope at tested sites averages 16-180 - Topographic location acceptable - Site drainage looks good - HOUSE SITING CAPABILITY - I RECOMME�D E ALLOW LESS THAN A 100 ' HOUSE SETBACK TO BAYSIDE ROAD, IN ORDER TO M NIMIZE POSSIBLE HOUSE ENCROACHMENT ON DRAINFIELD AREAS - Reported perc rates averagelo MPI in to foot of soil, both sites - Depth to seasonal saturation zone 4-5 ' - Soil survey indicates Kilkenny Loam - BECAUSE OF THE STEEP SLOPES, I WOULp R COMMEND THE TRENCHES BE NO WIDER THAN 2 ' - Based on depths to seasonal saturation indicated, the primary site should have a maximum trench depth of 1 ' , and the alternate site trenches no deeper than 2 ' - As for the site evaluator ' s notes, a c rtain drain might have some benefit here , although its effect might be t�in mal due to the fine soil textures present Lot 2 ( Sites l0A & lOB) - Slope at tested sites averages 12g - Topographic location - OK, but this is a slightly concave slope which will tend to hold water, so additional site drainage work may be beneficial during construction - House siting capability - I recommenld hat specific house site "envelopes" be established to protect drainfielc� s ' tes #804 - Painters Creek April 17 , 1984 Page 2 ', - Reported perc rates averaged 16 MPI rimary, 18 MPI alternate in top foot of soil - Depth to seasonal saturation zone rep rted at 4-5 . 5 ' - Soil survey indicates Kilkenny Loam a tested sites - Again, I would recommend 2 ' wide tren hes maximum, not more than 1 ' deep - A curtain drain may have some benefit, but the borings again indicate fine textured soils which resist drai age Lot 3 - (Sites 11A & 11B) - Slope at tested sites averaged 12-18$ : - Topographic location - good - Site drainage appears OK - House siting capability - poor- due t road and drainfield site location , a 50 ' setback places the likely house location just above the drainfield site . I would suggest either reali�gni g the road or allowing a setback less than 50 ' to the road outlot. Bec use the sites extend the width of the lot, the shape and location of house would appear quite limited if no changes are made - Reported perc rates average 13 MPI pri ary, 23 MPI alternate at the tested site - Depth to seasonal saturation zone 4 ' -5 ' ; trench depths could possibly be 18-24" in primary site, 12" in alterna e site - Soil survey indicates Kilkenny Loam - Recommend maximum trench width 2 ' due o the slopes Lot 4 (Sites 12A & 12B) - Slope at tested sites averages 8-16� - Topographic location - OK - Site drainage - OK - House siting capability - Appears OK, ouse site establishment recommended - Reported perc rates average 33 MPI pri ary, 6 MPI alternate , in upper foot - Depth to seasonal saturation reported t 4 . 5-5 . 5 ' - Soil survey indicates Kilkenny Loam at tested sites - Trench system should be no deeper than 2 ' in primary site , 18" in alternate site , suggest trenches 2 ' wide maximum Lot 5 (Sites 13A & 13B) - Slopes at tested sites average 2-10$ - Topographic location good - Site drainage OK, note that drainfield sites for Lots 5 & 6 are adjacent - House siting capability - OK, recommen establishing a house site envelope to protect drainfield areas - Reported perc rates average 34 MPI pri ary, 20 MPI alternate - Soil borings indicate better-drainec� s ils, seasonal saturation zones below 5 ' . Trenches can be up to 2 ' de p, 3 ' wide, may need basement lift pump #804 - Painters Creek April 17, 1984 Page 3 Lot 6 - (Sites 14A & 14B) - Slopes at tested sites 10-15$ - Topoqraphic location OK - Site drainage OK - House siting capability - This one mig t be a problem due to location of road/cul-de-sac, drainfield site lo ation and steep slope location. Suggest a specific house site "envelop " to protect drainfield area - Reported perc rates average 19 MPI pri ary, 3 MPI alternate - Seasonal saturation zones 4 ' -6Z ' . A c rtain drain would likely be beneficial and allow trenches up to 2 ' deep Lot 7 - (Sites 15A, 15B, 7A (4/11/84) ) - Slopes at tested sites 0-lOg - Site drainage qood, topographic locati n good - Pump station likely needed due to prob ble preferred house location at high point of lot - Reported perc rates 12-16 MPI overall - Based on soil borings, the preferred si e is to the northwest just above the steep slope, where use of a curtain dr in would likely be beneficial and allow the use of shallow trenches. Th other two sites would appear to be suitable for mound systems; if a curtain drain could be installed to effectively drain this soil, shallo trenches might be possible Lot 8 - (Sites 16A, 16B, 8A (4/11/84) ) - Slope at tested sites is 6-12$ - Topographic location - above wet areas nearing base of slope - House siting should be no problem - Site drainage - may need some diversio around drainfield sites - Seasonal saturation zones reported at Z' -4 ' - Perc rates at the tested sites average 15 MPI primary, 75MPI alternate - Based on perc rates and water tables, would recommend mound systems for both sites. A shallow trench system m ght be possible at the primary site if a curtain drain effectively lo ered the water table . That may not be possible in the clayey soils pr sent 9 - (Sites 9A (4/11/84) & 9B (4/11/84) ) - Slope at tested sites 20-6� - Topographic location good - Site drainage good - House siting capability - should be '� no , problem - Perc rates average 15 MPI primary s�te 9 MPI alternate site - Saturation zones at 42-48" . Based n he information submitted, both sites are suitable for mound system$ a d may be suitable for shallow trenches if a curtain drain can be use to drain the soils #804 - Patiners Creek April 17, 1984 Page 4 Lot 10 - (Sites 17A, 17B, l0A (4/11/84) a d lOB (4/11/84) ) - This lot was retested since the ori�in 1 sites were located in a low drainage area -- , - The new sites are located on slopes of -about 10$ - Perc rates averaged 11 MPI primary � " , 13 MPI alternate site - Seasonal saturation zones at 44-50" a rimar . site would allow shallow trenches if a curtain drain is used to lower the seasonal water table . The alternate site should support a st ndard trench system. The proposed house location near the southeast lot orner may not be feasible and a lift pump might ultimately be required for this site SUMMARY Al1 ten proposed lots have sites which ap ear suitable for septic systems . On Lots 1-7 , the drainfield site location place some limitations on usable house sites . I recommend that house site "envelopes" be incorporated into the plat to help preserve the tested drai field sites. Curtain drains may be of some benefit to certain site5 a d allow the use of shallow trench drainfields rather than mound systems . Based on the information submitted, I �ec mmend approval of this PRD. The developers should be notified it is thQir responsibility to keep all traffic , grading, fill, etc . away from the test�d ites . I I � � I � � Michael O'Donnel l, C'E.

Since the reporting of the s il tests dated December 9, 1983, the number of lots planned for. this site was reduced from twenty to ten. Soil testing was requested by the site p anner and the City of Orono in the general area of lot 9, as well as additi nal testing in other areas. The testing was conducted in a similar m nner as that described in the soil report dated December 9. The method of locating tests and test notation was also the same as shown in the earlier rep rt. Basically, two test pits and four percolation tests were performed in primary drain field area, and one test pit and two percolation tests were p rfo�rmed in an alternate area. 1948 701h Avenue„North/Becker, Minnesota 5530H _:�'.".°f�-'�: Page two April 11, 1984 For your review, the field sheets are includ d with this report.

Since the terrain is rolling, curtain drain is advised to be included in the drainfield design in order to intercept runoff water from entering the drainfield area. This recommend tion was discussed with the site planner. i The summary also indicates a relatively fast ercolation rate for the fine-grained � soils at this site. It should be noted that ercolation rates do vary as - dependent on the season, precipitation, and g neral soil conditions. Because soil conditions and permeability char cteristics are variable across the site, it is recommended that the stakes defin ng the drainfield areas be surveyed.

This report represents the results of the recent field tesring r_onducted for the sewage treatment areas of the prop sed Pair►ter's Creek Development. The testing was performed in accordance wi h [he authorization of the site planner, Fon Bastyr and Associates, Inc. INTRODUCTION The proposed housing development will consist oE 20 single-family sites. Each site will have a primary and an alter ate drainfield area. According to the City of Orono's code, a soil invest gation must be completed before starting construction. The soil investiga ion shall determine ttie soil prcfile to a depth of at least 8 ft. in tw locations in the primary drainfield area and in one location in the alternate rea. In addition, 4 percolation tests must be performed in the primary dra nfield area, and at least 2 percola- tion tests in the alternate area. A preliminary soil investigation and orresponding percolation tests were conducted at this site by GA1E Consult nts, Inc. to determine the general geology and feasibility in developing t�is site. In reviewing this informa- 1948 70th Avenue Nurth/Becker, Minnesota 55308 Painter's Creek Development 2 December 9, 1983 tion with the site planner and the Univer ity of Minnesota soil consultant, . James L. Anderson, it was concluded that drainfield system consisting of shallow trenches would be preferred for t ese lots. In order for thia system to be effective, the seasonal grou dwater table (as determinPd by ' soil mottling) must be below a depth o� 4 ft. and tE�e soil at the plan deptti of the shallow trenches must have a percolation rate faster than 60 minutes per inch. I CONCLUSION In the majority of the originally� pr posed drainfield areas, the seasonal groundwater table was encountere at a 4 ft. to 6 ft. depth. Fiowever, in 8 of the areas, the seasonal roundwater table was higher than a 4 ft. depth, and the site planner de id d to relocate these drainfield areas to more feasible areas. The new ar as were examined and tested with satisfactory results. With the exception of the alternate rainfields on Lots 16 and 20, the soils in the remaining proposed drainfiel areas had an average percolation rate of 60 or less. The test resu�ts ind ate the shallow trench drainfield system would be feasible at this site in n arly all of the tested areas. In the alternate drainfields on Lots 16 and 2 , "mound" systems were recommended. Please refer to the Test Summary Sheet for more specific information. TEST PROC�DUR Location Staking was provided by the site planler to define the primary drainfield area ("A") and the alternate drainfield ar as ("B") . The soil profile Painter's Creek Development 3 December 9, 1983 in each of the proposed areas was initiall determined by excavating a test pit in the center of [he originally designated areas. In areas where the seasonal groundwater table was e countered at a de th of less than 4 ft. , the drainfield areas were r�lo ated to areas where satisfactory results were obtained. A sketch is attach d with this report showing the final locations as tested. A minimum of two percolation tests we e conducted in each of the designated areas. Percolation test No. 1 as located 30 ft. in either a northerly or easterly direction along the en th of the drainfieid area from the center of the drainfield area. T e actual direction would depend on the orientation of the drainfield. �er olation test No. 2 was located 30 ft. from the center in the opposite dir ction. In the preliminary drainfield areas, wo additional percolation tests were performed. Percolation test No. 3 wa located 10 ft. in either the northerly or easterly direction along with width of the drainfield area from the center, and percolation test No. 4 was located 10 ft. from the center in the opposite direction. In addition, a second test pit was excavated at the location of the percolation test No. 1 PT-3 PT-2 O Sa-� PT-I 58-2 PT-4 � � � Painter's Creek Development 4 , December 9, 1983 Soil Profile The soil profile was determined using a backhoe to excavate a test pit to a depth of 8 ft. By examining the side alls of the test pit, a more accurate evaluation of the soil profile an change in strata co�ld be made on a continuous basis. After the soil pro ile was recorded, the test pits were backfilled. The soils encountered were visual�y a d manually classified in accor- dance with the Unified Soil Classifica�ion System. The soil description consisted of soil texture, color, moisture content, depth of mottling, and any lenses of other soils or degree of cob les and boulders encountered. The capitalized letters in parentheses fol owing the soil description is the soil classification. The soil profile at each of the lots are shown on the attached sheets corresponding to the 1 t numbers. Percolation Test The percolation tests were conducCed n accordance with the procedure outlined in the University of Minnesota Ex ension Folder 261. A 6 in. diameter hole was dug with a hand auger to a measured depth of 12 in. The bottom of the hole was cleaned, and the bo tom and sides were scraped with a knife to remove smeared surfaces. Appro imately 2 to 3 in. of washed 3/4 in. to No. 4 aggregate were placed in he bottom of each of the holes. The holes were then filled with water and llowed to soak for 24 hours. In most of the holes, the water drained by th following morning; however, measureable rain during the night made the ground saturated before running the test. . Painter's Creek Development S December 9, 1983 The test consisted of making 4 to 6 r adings of the water level at - 5-to 30-minute intervals. The percolation rate was determined in ttie field after a steady uniform flow condition was aintained. The actual test results are tabulated on the Test Summary heet. TEST RESUI.TS In Lots 2, 4, 9, 14, 15, 19, and 2�, he seasonal groundwater table was encountered at a depth of less than 4 t. Therefore� these drainfield areas were relocated by the site planner t more favorable areas where satisfactory results were obtained. It sho ld be realized that ttie season- able groundwater table at this site is relatively high, with depttis ranging from 1/2 ft. to 6 1/2 ft. in the tested are s. This can be due in part to the stiff, low permeable glacial till sqils at this site. The majority of the soils tested fqr p rcolation consisted of topsoil (A--�orizon) . Percolation rates were genera ly in the range of 4 to 60 minutes per inch. The faster rates were re orded in the areas of deeper topsoil (A horizon) , while the slower rates were found in the areas of shallower topsoil and represent the percola ion rate of the B-tiorizon soils. In alternate areas for Lots 16 and 20, percolation rates of slower than 60 minutes per inch were recorded. As discussed with the site planner� these areas will be designated as "mound" s stems only.• It is possib]_e to conduc[ further exploration for more suitab e soils, if you so desire. RErIARKS As indicated by the test results, t'�e oils at this site are quite variable in their soil texture and permeabi ity characteristics. Drainfields .Y�,y' . i i� � Painter's Creek Development �' - December 9, 1983 that are mislocated in an area different f m that as staked in the field could have substantially different results han designed. It is recommended the stakes in the field be surveyed in orde to relocate the drainfield areas as tested. The topsoil (A-horizon) strata was fou d to have a faster percolation rate than the underlying soils. In this re ard, it is suggested to maintain as much of the topsoil as possible in the d ainfield area and to limit the depth of the trenches where the topsoil thi kness is thin.

Attn: Jerry Re: Residence under construction at 4440 Bayside Road, Orono Dear Jerry: On August 16, 1988 , I met with Dale nd Dave of K's Mechanical and we were able to revise slightly the pr posed location of the primary drainfield sites so that they can constr ct a trench system in the general area that has not had the topsoil rem ved. However, the system to be constructed now will take up all the �re that had been tested for primary and alternate sites. Therefore, it w�. l be necessary to have additional soil testing done to determine the lo�ca ion for a suitable alternate site for future use. One possibility would b just north and slightly downhill from the initial system, although othe possibilities may exist on the property. This testing must be completed before a Certificate of Occupancy will be issued, hence I suggest you star now to line someone up. Additionally, during the discussions with the septic contractor, it became apparent that the tank location, hile uphill from the low drainage swale east of the house, could be jeopard' zed if a culvert is not installed under the driveway. I would note to ou tha� the approved site plan distinctly requires that the 20' easemen drainageway be maintained, since topographical data from the original s division indicates that drainage heads generally southwest through th property. A culvert must be installed across that driveway at the pr per elevation to maint�in the pre- existing drainage pattern. Although it is unfortunate that this came to light after the driveway had been paved, it was something that was required in the plan approval in 1987 and must b installed prior to issuance of a Certificate of Occupancy for the house.
