Septic System Permit Renewal
Dear On-Site Services Engineer:
The permit (OSP221247) for the construction of a well and septic system on the subject property
has expired. A site visit was conducted, and while the home is in the process of construction, there
are no substantial changes to the design or location of the septic system since this permit was
originally issued. The well has been installed, and we have confirmed 50’ separation to the septic
site for the tank and field. We will be finalizing the new confirmation test hole and the installer is
looking to begin next week. We request a permit renewal.
Sincerely,
Benjamin Schiller, PE

Subject: Palaterra Addn 2, Lot 5 – NHN De Palatis Cir
Septic system design
Dear On-Site Services Engineer:
The owner of the above lot intends to build a 4-bedroom home on the property, so we are
submitting this permit application for the construction of a new well and septic system. The
attached site plan identifies the location of the home as well as the proposed well, septic location
and alternate site. No conflicts exist between this proposed system and any other well or septic
system, whether on this lot or adjacent lots.
The ground surface on the lot slopes away from the road moderately in the front part of the lot, but
drops off toward the back. It is in that flatter area that the new septic system is located. (There are
no slopes greater than 25% within 50 feet downslope of either the primary or alternate site.)
Stormwater drainage will not impact this septic system. The new trench will be constructed parallel
to the slope as much as possible.
Wells on this and adjacent lots are shown. The new system will be a minimum of 50’ from all
wells and surface water, and more than 5’ away from the septic tank. The alternate site is located
more than 16’ away.
Please refer to the attached test hole logs, soils lab analysis, plan and profile pages for the septic
design. If this design is followed, there will be no adverse impacts to adjacent properties.
Sincerely,
Benjamin Schiller, PE
