The following summary provides specific data that will be necessary before these reports can Re a< opera be used to design mound private on-site wastewater treatment systems 7 3864677 (POWTS): R cling -.386-4675 Lot 17 - Due to extensive grading at the rear of this lot, adjacent to a drainage easement and walking trail, the NE corner iron pipe benchmark may have been altered and its elevation may not be accurate for POWTS installation. You did not correct the problem with alternate Benchmark at elevation 1075.24', which is shown on the plot plan as being located higher than the 1076' contour line. Boring 131713 elevation is at 1076.28' and appears to be below the benchmark on the plot plan. (Note: This same benchmark is also wrong on lot 18 soil report, but another benchmark can be used for that system's design) In addition, you cannot arbitrarily modify the contours for the site plan from the original engineer's plan. You need to find the benchmark and obtain an accurate elevation so that a POWTS installer can use it to establish a contour for the mound. dry �Q Lot 22-You cannot add contour lines to the engineer's drawing to make the contour a eva ions work. The corner iron pipe elevations and borings B-22A and A � B-22C appear correct, but B-22B had an elevation of 1033.27' at a location on r� the plot plan between contours 1026' and 1028'. Either the boring was much r higher on the slope than indicated on the plot plan or a math error was made when Ogden's survey crew gave you the elevation data. By modifying the plot Gya,k- plan to add contours, you now created a 22% slope where a 7% slope was originally shown. Has the site been cut or altered?? You need to verify the actual elevation on your boring B-22B and provide that data before a mound design can be developed for this lot. 1ALWO Pbl?4,bA"z� J 0`-- Sr.CRO/X COUNTY GOVERN T CENTER 1 101 CARM/GHAEL ROAD,HUD N, W/ 54016 7153864686 FAx WWW.CO.SAINT-CROIX.WI.US PZCJQ CO.SAINT-CROIX.WI.US i Please rgI'se e p o pi�ans an a eva ion a a so a e soi repo s may e r sed�f r"�is " in POW S design or issuance of a sanitary permit.

He will review your comments and revisit the sites to determine if contours and benchmarks need to be corrected. In the letter it was insinuated that I modified and added contours to make them work and that I cannot change engineers plans. I would appreciate not being accused of doing something wrong. Those changes were made by the Engineering Company and besides if they are attached to my signed documents, they become part of my report. Therefore, I am requesting a letter of apology and one sent to all parties that received the original letter as that letter is damaging to my reputation.

The following summary provides specific data that will be necessary Real perty before these reports can be used to design mound private on-site wastewater treatment 7 386-4677 systems (POWTS): R cling 75 Lot 1 The soil application rate that must be used to calculate mound basal area (0.2 gpd/ft z) requires a long, narrow mound with a linear loading rate of<4.5 gal./ft./day. The existing tested area allows a maximum mound length of 90 feet, which is likely too short to meet the linear loading rate requirement. In addition, the elevation reported for boring R-1A is incorrect and must be re-measured to provide an accurate contour elevation for mound design. Lot 4—the entire original soil-tested area was covered during excavation and grading of the building pad. From an on-site investigation made 1/17/06, 1 observed that a crescent- shaped area of undisturbed soils remains between the toe of the filled building pad and the 20% slopes at the rear of the lot. According to Ms. Hollister, there is another boring (R-4E) that was not included in her submittal, but is located in this undisturbed area. She needs to submit an amended soil evaluation report that includes a profile description and shows the location of this boring so that a contour can be established for a mound. In addition, both benchmark elevations need to be checked and verified, since the elevations are 0.91' and 2.05' higher than the contour 1066' shown on the plot plan. The amended report must be completed before a design can be created for a proposed POWTS. Please note, Ms. Hollister is a CST, but not a POWTS designer, so plot plan and mound plan view calculations she has prepared, indicating a location for a 33' x 124' mound, are only an example of what might work after the soil data has been provided. Lots 10 & 11 — I made a note regarding inconsistencies for BM @ 1077.15, which is shown in different locations on each plot plan. I recommended using the alternate lot corner I. P. benchmark @ 1075.10' to avoid errors in establishing mound contour elevations. Lots 1, , ,910, 11, 14 �ies 1 J22 24, 25, 31, 32, 34, 40, 41, 45, 46 &62 - On all the above here are discrep een the elevations and test pit locations compared to the contours shown on Ms. Hollister's site plans. In a telephone discussion t715386-4686 ST.CRO/X COUNTY GOVERNMENT CENTER 1 10 1 CARM/CHAEL ROAD,HUDSON, W/ 54016 FgY PZC�CO.SAINTCRO/X.WI US WWW.Co"' i Page Tw — ids ol"roy poi eporsr Mary Jo ollister, I was informed that most of the elevations reported for soil test pits were provided by the surveyor art of developing the preliminary plat. The individual soil report plot plans were created using copies of th liminary plat to show 2' contour intervals on the lot and locations of Mary Jo's test pits. When usin n Sea Level elevation (as opposed to an assumed elevation), the contours should be consistent he elevations given for each test pit on the plot plan. Some of the discrepancies may be a result of c largement and scale that are not 100% accurate. However, my concern are errors that range from A to more than 6 feet difference in elevation, which is unacceptable. All reports that have discrepancie reater than 0.75' will be set aside and copies mailed to Mary Jo for re-calculation and/or corrections b re the reports will be released for use in designing POWTS. Our office, as a 'governmental unit"for the state, is required by WI Comm 85.50 to complete soil report reviews withi months of receipt; these reports were submitted on 10/25/05. Please feel free to contact me if you a questions regarding the soil report review or status of individual lot reports.
