Subject: River Hills Est Lot 4
Septic system design
Dear On-Site Services Engineer:
The owner of the above lot intends to build a 3-bedroom home on the property, so we are
submitting this permit application for the construction of a new well and septic system. The owners
intend to build garage as first stage of construction and would like to install the on-site system
prior to construction of the home. The attached site plan identifies the location of the garage 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 toward the south steeply, but toward the north the slopes are
much milder. It is in that flatter area that the new septic system is located. Elevation markers are
shown on the site plan showing the grade and direction of flow. While there are slopes steeper than
25% within 50’ of the system, an attached analysis demonstrates that the effluent will not daylight
for over 70’, and so it meets the ‘steep slopes’ provision of the code, with no special justifications
needed.
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 6’ away. Stormwater drainage will not impact this septic system. The new trench will
be constructed parallel to the slope as much as possible.
Please refer to the attached test hole logs, steep slopes cross-section, 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
