Septic System Design and Permit Application
Impacts to Adjacent Properties
Dear Onsite Services Engineer:
The existing absorption pit on the subject lot has failed and must be replaced. We are
therefore requesting a permit be issued for the upgrade of the septic system to
accommodate the three-bedroom home on the lot. The septic system will be
constructed to serve a future four-bedroom home. The attached Site Plan and backup
documentation identify the location and configuration of the existing and proposed
septic system. The existing absorption pit will be decommissioned in accordance with
Municipal Code. Also identified on the plans are the locations of the existing well on
this and adjacent lots and adjacent septic systems. No conflicts exist between the
proposed septic system and the wells on this or adjacent lots. Protective radii are
shown to the adjacent wells. Drainage arrows are shown indicating the current
drainage patterns. The drainage patterns will be maintained after construction.
The test hole placed on the lot indicated Silty Gravel with Sand (GM) to a depth of 15'.
No groundwater was encountered during placement of the test hole and none has
developed during the monitoring period. The percolation rate in the GM soil lense was
determined to be less than 5 minutes per inch. We have designed the new trench with
an application rate of 1.2 gallons per day per square foot. We are proposing to place a
50' long by 5' wide absorption trench with a 4' effective depth. The total depth of the
system will be 8' with the distribution line at 4' below the existing surface.
The ground surface on the lot is virtually fiat in the area of the absorption trench with a
slight bias to the south. The trench will be placed parallel to the contours of the ground
as much as possible and in conformance with design criteria. A minimum of 100' will
be maintained between all components of the septic system and the proposed well and

from any surface water in the area.
If the system is constructed in accordance with our design the following statements
apply:
]. The system, if constructed as designed, will have no adverse impact on the wells
in the area or those to be constructed in the future.
2. The system, if constructed as designed, will have no adverse impact on existing
septic systems in the area or those to be constructed in the future.
3. The system, if constructed as designed, will have no adverse impact on reserve
space, either surface or subsurface, on any lots located in the area.
4. The system, if constructed as designed, will have no adverse impact on drainage
patterns in the area. The current drainage pattern will be maintained.
Sincerely,
Michael E. Anderson, P.E.
