Lot 10, Block 1, Cross View Estates Subdivision
Septic System Design and Permit Application
Impacts to Adjacent Properties
Dear Onsite Services Engineer:
The owner of Lot 10, Block 1, Cross View Estates Subdivision intends to construct a
new five-bedroom home on the lot. We are therefore requesting a permit be issued for
the construction of a new well and septic system to accommodate the home. The
attached Site Plan and backup documentation identify the location and configuration of
the proposed well and septic system along with the alternate site. Also identified on the
plans are the existing wells and septic systems on surrounding lots. No conflicts exist
between the proposed septic system and well or septic systems and wells on adjacent
lots. Drainage arrows are shown on the site plan showing the grade and direction of
flow on the lot. The drainage pattern will not be changed as a result of this project.
Two test holes were placed on the lot in the area of the absorption trench and alternate
site. The logs indicate silty gravel (GM) in the zone specified for the absorption trench.
The percolation rate of the soil was determined to be 1.25 to 11 minutes per inch. No
groundwater was found during the placement of the test hole, but was found at 13'
during the monitoring period. An application rate of .8 gallons per day per square foot
was used in the design of the absorption system. We are proposing to place a new
1,500-gallon septic tank and a 94' long by 5' wide by 4' effective depth absorption
trench to treat and dispose of the effluent generated in the house. The elevation of the
distribution line in the absorption trench will be 4' below the surface and the total depth
will be 8'. A minimum of 3' of fill or 2" of insulation and 2' of fill will be placed over the
absorption trench and 4' over the septic tank.
The ground surface on the lot in the area of the septic system slopes to the northwest.
The new trench will be constructed parallel with the contours of the slope as much as
possible in conformance with Municipal requirements. The new septic system will be

constructed a minimum of 100' from all wells and any surface water and 10' the
proposed and existing water services 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.
The system, if constructed as designed, will have no adverse impact on existing
septic systems in the area er those to be constructed in the future.
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.
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.
