Subject: Lot 3, Block 1, Riverpark View Subdivision
Septic System Design and Permit Application
Impacts to Adjacent Properties
Dear Onsite Services Engineer:
The owner of Lot 3, Block 1 , Riverpark View Subdivision intends to construct a new
three-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 in the area and septic systems on surrounding lots. No
conflicts exist between the proposed septic system and the existing septic systems and
wells on this and adjacent lots. Drainage arrows and ground surface contours 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.
The test holes placed on the lot in the area of the absorption trenches and alternate site
indicate gravel (GM/GW) with varying amounts of sand and silt. The percolation rate of
the soil was determined to be 1 to 5 minutes per inch. No groundwater was found
during the placement of the test holes and none was found in either test hole during the
monitoring period. An application rate of 1.2 gallons per day per square foot was used
in the design of the absorption system. We are proposing to place a new 1 ,000-gallon
septic tank and a 38' 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 3.0' below the surface and the total depth will be 7.0'. 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 southwest
at a shallow grade. The new trench will be constructed parallel to the ground contours
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.
Lot 3, Block 1, Riverview Park
June 12, 2017

If the system is constructed in accordance with our design the following statements
apply:
1. 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,
