Subject: The Cascades, Block 1 Lot 1 – NHN West River Dr
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
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 steeply from the west to the east. The slopes become more
moderate below the house closer to 20% all the way to the road. The proposed system is located
right in the area that the slope mellows out. There are no slopes greater than 25% within 50 feet
downslope of either the primary or alternate site. Contours are shown on the site plan showing the
grade and direction of flow. 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 6’ away. Please refer to the attached test hole log, 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
