Legal Description: T12N RM SEC 33 LT 125 120'X 135'
Engineer: Forge engineering
Your request for a waiver of the required 10 feet horizontal separation from the disposal field to
the property line has been approved. The approved separation distance is 5.9 feet. The
Inspection Report and Record Drawings show, after the fact, that the separation from the field to
the North property line is 1.6' and 1.7' to the West property line on the South end of the trench.
These separations have been approved and this waiver is amended 9/30/2025.
The field is also approved to be installed not parallel to the contours.
This waiver approval applies to the proposed disposal field only. Any future upgrade to the on-
site wastewater disposal system will require all separation distances be met or another approval
from this department.

Waiver amendment
Dear On-Site Services Engineer:
We are requesting an amendment to the waiver for the trench installation. During the installation,
the contractor had to adjust the trench at the north end to account for the electrical pedestals. This
adjustment moved the trench closer to the lot lines.
Therefore, we are requesting that the waiver be amended to 1.6’ to the lot line at the north end and
1.7’ on the southwest lot line.
Sincerely,

Septic system design and waiver requests
Dear On-Site Services Engineer:
This permit application is for the construction of a new septic system on the above referenced lot
due to a failed existing system. The attached site plan shows the locations of the home, well and
the proposed septic system. The proposed system does not conflict with any existing wells or septic
systems on any adjacent lots.
The lot is small with a gentle northern slope. To properly fit the system, it must run with the
contours, resulting in varied depth from 9’ maximum in the south to 4’ in the north. This would
result in a coverage of 6’ in the south and 1’ in the north. Max depth has been measured from the
highest point, and where the cover is less than three feet 2” of insulation will be required.
This lot is not large, and it is difficult to stay outside the well radius. The only way to fit a system
is to encroach on the setbacks for the west and north property line. In addition, a portion of the
traveled way for Maxwell Place encroaches informally onto this lot, so the trench must remain
outside of the gravel. Our best measurements indicate that the system will be 5.9 feet from the
west property line and 7.6 feet from the north property line. We are requesting a waiver for both
encroachments. There are no adverse effects to adjacent properties from these encroachments.
The site plan includes contours illustrating the grade and flow direction as well as the distances of
the field to the property line. Storme drainage will not affect this septic system. The new system
will be a minimum of 100 feet from all wells and surface water, and more than 5 feet from the
septic tank. Please refer to the attached test hole log, plan, and profile pages for the septic design.
Adhering to this design will ensure no adverse impact to adjacent propertied

Benjamin Schiller, PE
