Subject: Gold Pan Estates, Lot 3 – NHN Old Seward Highway
Septic System Design
Dear On-Site Services Engineer:
The owner of Lot 3, Gold Pan Estates 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 septic
system to accommodate the home. Water to the home will be provided from the Class A Well
and Water System on the adjacent lot. The attached Site Plan and backup documentation identify
the location and configuration of the proposed 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.
The ground surface on the lot in the area of the septic system slopes to the southwest. 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 200’ from the Class A well and 100’ from all private wells and any surface water and 10’ from
the proposed and existing water services in the area. Ground surface contours are shown on the
Site Plan. Storm water drainage will not affect the proposed septic system.
Groundwater was recently found at 7.5’ below the surface. No groundwater was found during
placement of the test hole in late June of 2013 to a depth of 18’. It is thought that much of the year
the area is free of groundwater to depths of at least 18’. The lot immediately to the south with a
test hole approximately 200’ away indicated no groundwater to 14’ on 10/22/19. Similarly, the
lot directly to the southwest and approximately 250’ away indicated no groundwater to 20’ on
8/13/2018. The ground surface approximately 500’ to the south ends in a steep slope which drops
rapidly toward Cook Inlet. We can logically assume the groundwater found recently on Lot 3 is
at or near its highest level of the year and should start to drop immediately as the fall rains have
now ceased. The absorption trench for the proposed septic system on this lot is designed for a
CO#1
groundwater elevation of 7’ which is .5’ higher than the elevation of the water recently encountered
on site. We are confident this is more than acceptable to meet current Municipal Code.
Please refer to the attached test hole log 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

Septic System Design and Permit Application
Impacts to Adjacent Properties
Dear Onsite Services Engineer:
The owner of Lot 3, Gold Pan Estates Subdivision intends to construct a new three-
bedroom home on the lot to serve as a parsonage for the Saint Tikhon Russian
Orthedox Church. 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.
A test hole was placed on the lot in the area of the absorption trench and alternate site.
The log indicates well graded to silty gravel (GW/GM) in the zone specified for the
absorption trench. The percolation rate of the soil was determined to be 1.4 minutes
per inch. No groundwater was found during the placement of the test hole and none
was noted 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 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 southwest.
The new trench will be constructed parallel with the contours of the slope as much as
Lot 3, Gold Pan Estates Subdivision
July 7, 2013
Page Two
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 or 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.
