Septic System Design and Permit Application
Impacts to Adjacent Properties
Dear Onsite Services Engineer:
The owner of Lot 7, Block 1, Skyhills Subdivision No. 1 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 septic system to accommodate the home. The subdivision is
currently served by the AWWU Water System. The attached Site Plan and backup
documentation identify the location and configuration of the proposed septic system
along with the alternate site and the proposed water service. No existing wells or septic
systems conflict with the proposed septic system. 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.
The test holes placed on the lot in the area of the absorption trench and alternate site
indicated silty sand with gravel (SP/SM). The percolation rate in was determined to be
7 minutes per inch. No groundwater was found during the placement of the test holes
and none was noted 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 60' long by 3' wide by 8'
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 2' below the
surface and the total depth will be 10'. 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 absorption trench slopes to the east at
a 10% grade. A 50% slope exists near the property line which extends to the dry ditch
approximately 4' below the top of the slope. A slope waiver is attached describing the
slope. The new trench will be constructed parallel with the contours of the slope as
Lot 7, Block 1, Skyhills Subdivision No. 1
May 14, 2012

much as possible in conformance with Municipal requirements. The new septic system
will be constructed a minimum of 100' from any surface water and 10' from 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.

FROM:
Mike Anderson, P.E.
SUBJECT:
Lot 7, Block 1, Skyhills Subdivision No. 1
Septic System Permit No. OSP121080
We have made the following revisions in accordance with your comments:
1. Subsurface soils throughout Skyhills Subdivision are very consistent and include
well graded sand with some silt. In almost every case the percolation rate is less
than 5 minutes per inch. This system is designed for a slower percolation rate of
between 6 and 15 minutes per inch. Test Hole No. 63 on this lot is primarily
sand with a percolation rate of less than 5 minutes per inch. We are confident
the subsurface soils in the area between TH 62 and TH 63 are consistently clean
sand.
2. The alternate site has been redesigned and moved to provide additional
separation distance from the break in grade. At the new location the break in
grade is much less dramatic. Placing the alternate site at this location will result
in the imaginary 25% slope not daylighting.
3. The retaining wall is shown on the Site Plan. The primary absorption trench has
been moved to the south and is now nearly 22' from the property line. At its
closest point it is nearly 35' from the retaining wall. The imaginary 25% line does
not daylight when extended toward the retaining wall. The CPP found in the
drainage ditch appears to be a culvert under the driveway. The ditch and culvert
have remained dry over the past two weeks, the
wettest period of he year.

Absorption Trench to Slope Waiver
Dear Onsite Services Engineer:
A dry ditch was constructed along the frontage of Lot 7, Block 1, Skyhills Subdivision
No. 1 during the subdivision development and the construction of Skyhills Drive. The
backslope of the ditch is approximately 2:1. The top of the slope is 30' from the closest
edge of the proposed absorption trench and 14' from the closest edge of the alternate
trench.
The subsurface soil on the lot is clean sand with percolation rates between 2 and 7
minutes per inch. It is unlikely that septic effluent will ever migrate to and surface on
the backslope of the ditch.
Sincerely,
Michael E. Anderson, P.E.

In conducting this evaluation, GEG provided an engineering evaluation of the well and/or septic system
in accordance with the guidelines and regulations established by the Municipality of Anchorage and
industry practices. The reported results describe the condition of the system/s on the date/s of the
evaluation. Separation distances were measured to readily identifiable features. Hidden defects or
encroachments may exist that were not identified during the evaluation. The operational life of all wells
and septic systems depend upon a variety of variables, including but not limited to, soil conditions,
groundwater levels (that may fluctuate during the year), quality of construction (materials and
workmanship), and the water usage of the family utilizing the system/s. These conditions can vary, and
are outside the control of GEG. Satisfactory test results do not guarantee future performance of the
system/s; therefore, GEG makes no warranty (express or implied) regarding the future performance of
the well or septic system. GEG makes no representation whether an alternative well or septic system
can be installed on the property in the event either of the current systems fail to perform adequately in
the future. The content of this report is for the sole benefit of the person/party that retained GEG to
perform the evaluation. Reliance upon the information provided in this report by any other person or
party (including subsequent property purchasers) is not authorized, nor will it confer any legal right
whatsoever.
