Subject: Zona, Lot 139A – NHN S. Birchwood Loop
Septic System Design
Dear On-Site Services Engineer:
The owner of the above lot intends to build a 4-bedroom home on the property. 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 and the proposed well, septic location and
alternate site. No conflicts exist between this proposed system and any other well or septic
system on this lot or adjacent lots.
The ground surface on the lot is flat in the area of the proposed absorption trenches. There are
slopes greater than 25% within 50 feet down slope of the north end of the primary site, but the
trench is designed to comply with the steep slope provision of the ordinance. Our information
and site inspections show no slopes greater than 46% within 100’ of the absorption trench, but if
they are present no daylighting of effluent is probable. The Underlying soils in the area absorb
water at rates between 5 and 6 minutes per inch. No migration of effluent is expected other than
downward. Ground surface contours are shown on the site plan indicating the grade and
direction of flow. Stormwater drainage will not impact this septic system. The new trenches 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 100’ from all
wells and surface water, and more than 5’ away from the septic tank.
Please refer to the attached test hole logs and plan and profile sheets for the septic design. If this
design is followed, there will be no adverse impacts to adjacent properties.
Sincerely,
Michael E. Anderson, PE
