Enclosed with this memo are copies of a letter that was sent to the developer of
Real Pro Brown Wood Estates in 2005 notifying him of unuseable or deficient soil reports that
P _
715-3864677 were submitted for the lots. Adam Schumaker, the Certified Soil Tester, is no
longer licensed with the state and the deficiencies in his reports were verified during
Recycling a May 10, 2006 on-site investigation by Leroy Jansky, our state regional wastewater
75-386-4675 specialist at that time.
Each lot must be re-evaluated by a licensed soil tester, providing acceptable data to
allow for installation of a POWTS prior to our department issuing sanitary permits.
It has come to our attention with the recent submittal of an application for a permit
on lot 5 that current owners may not be aware of the problems our department
identified back in 2005.
Your cooperation will be much appreciated by anyone wishing to purchase and
build on a lot in Brown Wood Subdivision. A copy of this memo will be attached to
E: each of the soil reports on file so there will be no question about their accuracy or
viability.

fl. ~
reports submitted for these lots had benchmarks for establishing elevations for POWTS
Re cling designs. Lots 3 and 4 had unacceptable reports due to the use of a power auger instead of
-386-4675 excavated test pits. Other inaccuracies and/or misinformation have been detailed in the
memo, copies of which will be sent to the Town of St. Joseph and Dept. of Commerce.
Due to the lack of accurate data presented, none of the soil reports will be accepted for use
to obtain a sanitary permit until all data has been verified by individual on-site inspection.
The subdivision process for lot creation was allowed to continue, however, the final plat has
not yet been signed and conditions on the 10/25/05 committee approval include a $10/acre
inspection fee to partially recoup the cost for county staff time for the required on-site
inspections.
Please contact me if you have questions regarding the enclosed memo and the specific
deficiencies for this 14-lot subdivision.

Memo
From: Pam Quinn
Date: 11 /22/2005
Re: On-site Investigation of POWTS locations for Lots 1-14, Brown Wood Estates
Subdivision, Town of St. Joseph, Section 30, T30N, R19W
On November 14, 2005, an on-site investigation of Brown Wood Estates proposed POWTS
locations was performed at the request of the Town of St. Joseph. The town's concern was that
grading for road construction and drainage improvements had either damaged or entirely
removed proposed POWTS locations.
Alex Blackburn and I used the preliminary plat contour map and Adam Schumaker's soil reports
to verify data submitted for all 14 lots. We both have orienteering experience and can read
topographic maps and scale distances, so we found all the areas that were reported as POWTS
sites. A summary of our findings follows:
No benchmarks were observed on any of the 14 lots in the locations indicated
Each soil report identified a BM1 and BM2, however, no 1.5" PVC pipe markers were visible at
any of the soil-tested sites. The soil evaluation pages are dated 8/20/05 and the plot plans done
on 10/24/05, indicating that the POWTS locations existed only three weeks prior to the on-site
visit. Benchmarks should have been easily seen with the naked eye. This is a violation of
Comm 85.40(3)(a) which requires a benchmark on every report.
The actual distance between test pits does not match the distance indicated by a 1" = 40 ft scale
used on the plot plans.
By pacing between test pits on several lots, there appeared to be significantly less distance
between the pits, which would reduce the area available for POWTS construction. In addition,
mound sites need a specific length along a verifiable contour for system design. All 14 lots must
have the dimensions for the tested area measured with a tape or wheel to document actual size
and contour length prior to POWTS design.
Lot 1 required a complete soil report.
The original report plot plan had specific horizontal references from the north and east lot lines
to the proposed POWTS location, which has now been graded for construction of a driveway and
6

a stormwater retention area. CST Schumaker then produced a new plot plan dated 11115105 for
soil borings and benchmarks that are in a different area on the lot, but used the same elevations
and soil profile descriptions as the original report.
Machine-augered borings were observed on lots 3 and 4
This is a violation of Comm 85.20(3)2, which states "a soil boring may not be created by means
of a power auger". The soil profile descriptions are not acceptable; the holes had not been back-
filled and the deepest one observed extended to approximately 60 inches. The reported depths
on all pits were between 80 - 86 inches, describing the lowest profile as sandy loam with strong,
medium, granular (3mgr) structure. This appears to be falsified data, since augering would have
altered any structure in soils taken from the boring and the walls of the 18-inch diameter holes
smeared soil visible from above.
No backfilled test nits/borings were visible on lots 5 8 and 14.
• The area indicated for a mound on Lot 5 had no visible excavation for pits or borings.
Alex and I found the SE lot corner stake and walked 150 feet west to an area between two
drainage easements, as shown on the plot plan. Adam submitted a new soil report on
11115105 for a conventional POWTS in a different location on lot 5; all test pits locations
and elevations based on visible benchmarks must be verified by county staff.
• The original tested area on lot 8 appeared to have been damaged as part ofroad/driveway
construction, so a new soil report was completed on 11/14/05 showing a mound location.
This soil report will not be accepted by the county until another on-site has been done to
verify all three test pit locations, contour length, and elevations based on benchmarks, as
represented on the plot plan.
• For lot 14, Adam stated that he'd completed the soil evaluation a year and a half ago and
that's why there were no visible test pits in the areas shown on the 10/24/05 plot plan. A
soil report completed 4/30/03 for Jeff Brown is on file, but it is not in the same location
as the more recent report. A new soil report was completed 11/14/05 in a different
location - again, on-site verification will be required to identify locations for all three test
pits and benchmarks as required in Comm 85.20 and 85.40.
The soil descriptions for this parcel are suspect; the predominant soils are Amery and Santiago
series, both of which typically have reddish brown (5 YR 4/4) and/or yellowish red (5 YR 4/6)
massive sandy loams @ 31- 36 inches below grade. The soil profiles described have sandy
loams in the lowest horizon that range from massive (0m) to strong (3msbk) structure. Based on
soil survey data and observations of the material from the backfilled pits, the soil application rate
of 0.2 gpd/ft2 will be used for POWTS designs with a system elevation at or below 36" deep.
Individual on-site determinations will have to be scheduled to use any less conservative
application rate for sizing of a POWTS.
In general, much of the data submitted in order to create these 14 lots was either inaccurate or
misrepresents existing site conditions at the time of the site visit. Regardless of future plans to
relocate POWTS as part of house construction, each soil report must provide a minimum amount
of data on which to design a septic system. No sanitary permits will be issued based on these

soil reports until every lot has accurate, verifiable data and each POWTS location has flagged
benchmarks and borings.
