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 slopes to the southwest at grades approximating 24%. There are
slopes greater than 25% within 50 feet downslope of the absorption trenches. The trenches have
been designed to meet the steep slope provision of the Municipal Code. The ground surface at
the southeast end of the reserve area drops toward the road at a slope greater than 46%. The total
drop is 10’ and the surface then flattens to near level. The subsurface soil in the area is clean
gravel with a very fast percolation rate. Migration of effluent is not expected to occur as absorption
of effluent will be through the bottom of the trench. Ground contours are shown on the site plan
indicating 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 100’ from all
wells and surface water and more than 5’ 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
