Subject: Lot 4, Block 2, Riverpark View Subdivision
Septic System Design and Permit Application
Impacts to Adjacent Properties
Dear Onsite Services Engineer:
The owner of Lot 4, Block 2, Riverpark View Subdivision intends to construct a new
four-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 ,250-gallon
septic tank and a 50' 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 4.0' below the surface and the total depth will be 8.0'. 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 4, Block 2, Riverview Park

Page Two
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, itt'

ON-SITE WASTEWATER DISPOSAL SYSTEM
CONSTRUCTION AND MATERIAL SPECIFICATIONS
SUBJECT: LOT 4, BLOCK 2, RIVERVIEW PARK VIEW
GENERAL:
1. The scope of this project includes the procurement and placement of a new
1,250-gallon septic tank at the location shown on the Site Plan. Work also
includes the construction of a new 50' long x 5' wide x 4' effective depth
absorption trench at the location also shown on the Site Plan. The
distribution line in the trench will be placed at 4.0' below the existing ground
surface. Total depth of the trench will be 8.0' below the existing ground
surface. The new absorption trench and septic tank must be placed a
minimum of 100' from all private wells and any surface water in the area. A
minimum of 2' of cover with insulation is required over the absorption trench
and 4' of cover over the septic tank.
2. Construction shall be in accordance with the approved site plan, design
drawings, Municipal Permit with any special provisions or conditions, and all
applicable State and Municipal Wastewater Disposal Regulations.
3. The Contractor shall be responsible for obtaining all underground utility
locates and for the layout of the septic system and verification of the location
of all lot lines. The Contractor must also verify the location of wells in the
area and assure that the separation distances are met.
4. Unless specifically agreed otherwise, the contractor shall be responsible for
final grading areas subsequently depressed from soil settling. Property owner
shall be responsible for revegetation of affected areas unless specifically
agreed otherwise.
5. Contractors installing wastewater disposal systems must be certified by the
Municipal Building Safety Division On-Site Water and Wastewater Program
for system installations. Owners installing their own systems must receive
prior approval from the On-Site Water and Wastewater Program before
beginning system installation.
SEPTIC TANK INSTALLATION
1. A new 1,250-gallon septic tank must be procured from an approved source
and installed at the location shown.
2. A septic tank is to be constructed by a certified septic tank manufacturer.
Construction shall include two 4" cleanouts for pumping access.
3. The septic tank shall be sufficiently bedded to prevent settling or shifting of
the tank.
4. All standpipes on the septic tank shall extend a minimum of 12 inches above
final grade.
5. Tanks installed without 4' of cover shall have a minimum of 2" of direct burial
insulation.
6. A foundation cleanout shall be installed one to four feet from the building
foundation. Two cleanouts are required between the tank and the drainfield.
7. Final grading over the tank shall be such that a positive slope exists away
from the septic tank.
DRAINFIELD CONSTRUCTION:
1. The drainfield shall be constructed to the dimensions shown on the design.
The bottom of the trench shall be within 2" of level.
2. Distribution piping must be placed level with perforations down atop a level
bed of drainfield rock. Rock should then be placed over the pipe to provide a
minimum of 2" of cover.
3. A silt barrier or geotextile fabric must be placed between the drainfield rock
and the natural soil backfill.
4. Monitor tubes must be 4" in diameter and installed at the locations shown on
the design. The portion below ground must be perforated.
5. Contractor shall verify the septic tank and drainfield are a minimum 100' away
from any private water wells in the area, 150' from a Class "C" Well or 200'
