Dear On Site Services Engineer:
The owner of the subject lot intends to upgrade the crib on his lot to a
septic system which meets current Municipal criteria. We therefore
request a permit be issued to construct a septic system to serve the two
bedroom on the subject lot. The location of the system is shown on the
attached site plan. We intend to intercept the existing sewer service line
near the foundation of the house, place a new foundation cleanout and
install a new 1,000 gallon septic tank and wide drainfield.
Two testholes were dug near the area of the proposed trench. The soils
percolated at a rate of 40 minutes per inch. Testhole data including a
mechanical analysis of the soil is included for your review. Groundwater
was not encountered during the excavation of the holes, but minor
accumulation was noted after several days. The absorption trench has
been designed to maintain a minimum of 4' separation from the
groundwater to the bottom of the trench.
The existing absorption crib will be crushed and backfilled and left in
place. The new trench will be placed a minimum of 10' from the old crib.
The topography of the lot is noted on the site plan. The lot slopes gently
from south to north and is basically flat from east to west. All lots in the
subdivision are served by the Municipal water system and setbacks are not
a problem.
If the septic system is placed in the location shown the following
statements can be made:

Attention: Mr. Michael Lu
Subject: Lot 4, Block 1, King Subdivision
Existing Septic System
Dear Mr. Lu:
During the past week we have attempted to determine the size and type of
the septic system serving the house on Lot 4, Block I of King Subdivision.
No records are available so I have relied on the memory of the original
builder and the current owner of the property.
The two bedroom home was constructed in 1966. At that time a log crib
was installed to treat and dispose of the sewage generated in the house.
No septic tank was' placed .between the house and the crib. The crib was
apparently constructed of 15' long logs or ties interlocked together. The
original builder of the system stated the crib is 6' deep and probably 15'
long and 15' wide. The effective absorption area of the crib including only
the sidewalls is then estimated at 360 square feet. ;~
The exact depth of the crib is difficult to determine, but again the builder
stated it was constructed near the surface of the ground at that time. It
appears some fill may have been placed over the crib over the past 30
years. Assuming 2' of fill over the crib, the bottom is estimated at 8'
below the present ground surface. A testhole placed next to the crib to a
depth of 14' revealed no water seeping into the excavation. After two
days, °nly a minor accumulation was noted in the bottom of the hole and
this could be attributed to precipitation and surface runoff during that
Lot 4, Block 1, King Subdivision
October 30, 1995
Page Two
period. The groundwater table, therefore, is more than 4' below the
estimated bottom of the existing crib.
In summary, although the crib is nearly 30 years old it is still in good
working condition according to the present owner. He has had no problems
with sewage backup and no indication of surfacing effluent anywhere on
his property. He does intend, however, to install a cleanout into the crib
to allow pumping of the sludge on a regular basis.
The attached drawing indicates the location and estimated dimensions of
the crib. In addition, the soils log shows the depth of excavation, type of
soils encountered and groundwater levels in the area immediately
adjacent to the crib. It appears from all indications onsite and
conversations with both the owner and the original constructor of the
system that it was constructed in accordance with regulations in place in
1966. It also appears the crib is functioning adequately. To what degree,
however, is impossible to determine.
Sincerely,
Michael E. Anderson, P.E.

Impacts to Adjacent Properties
Dear On Site Services Engineer:
The owner of Lots 4 and 5, Block 1, King Subdivision is currently vacating
the common lot line. The new lot will be designated Lot 4A, Block 1, King
Subdivision. One condition to platting the new lot is the placement of a
septic system which conforms to current Municipal regulations to replace
the existing absorption crib on the lot. The owner has decided to place a
minimum 2,000 gallon holding tank in lieu of a standard septic system. We
are therefore requesting a permit to place a holding tank on the lot to
satisfy the condition to plat the new lot.
The attached site plan indicates the location of the new tank. The ground
surface of the lot slopes from south to north at a rate 1% to 2%. The
surface is basically flat from east to west. The subdivision is served by the
Municipal water system so well separation distances are not a factor. Other
septic systems in the area are more than 100' from the proposed location of
the holding tank. The watermain runs along 92nd Avenue and the service
line enters the house from the-front. ·
If the holding tank is placed in the location shown the following statements
can be made:
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
subdivision is currently served by the Municipal water system.
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 reserved space, either surface or subsurface, on any lots located in

The system, if constructed as designed, will have no adverse impact
on drainage patterns in the area. The current drainage pattern will be
maintained.

Lots 4 & 5, Block 1, King Subdivision
Subsurface Soils Analysis
Gentlemen:
On about June 10, 1995, a testhole was dug at the approximate common lot
line of Lots 4 & 5, Block 1, King Subdivision. The purpose of the testhole
was to analyze the subsurface soil conditions on the lot and to determine
whether the soil was suitable to support a proposed communication tower.
The hole was advanced utilizing a rubber tire backhoe and excavated to a
depth approximating 14'.
The topography of the lot gently slopes from the south to the north and
from the west to the east. Very little topsoil or organic material was
found in the area and much of the property appears to have been filled
with imported material. The lots are now covered with old abandoned and
wrecked vehicles in various stages of disrepair. A home is located on Lot
4 which is presently served by an onsite septic system. No information is
known about the system other than it has been in use for several years.
A soil sample was taken from the testhole and forwarded to EBA
Engineering, Inc. for a mechanical analysis. The results of their testing
are included with this report. The gradation generated in their lab
indicates the material is classified as a moderately graded, gravel
containing 24% silt. The frost classification would be F4 indicating high
frost susceptibility.
The walls of the excavation stood vertically indicating a very tight S0il
composition. No sloughing was evident. A percolation test was run
between 1' and 2' .to satisfy comments from the Municipality made during
the platting process° The material appears to absorb water at a rate of
40 minutes per inch indicating an onsite septic system could be placed in
Lots 4 & 5 King Subdivision
June 17, 1995
Page Two
this area if necessary.
The testhole soils include 4" of organic mat .at the surface. This is
underlain by the moderately graded gravel with silt to the bottom of the
excavation. No evidence was found of any organic layer to a depth of 14'
indicating this may be original material and no imported fill has 'been
placed in this area. The material is well compacted and should provide an
excellent base for the proposed communications tower. The groundwater
level stabilized at 12' below the ground surface. No seeping was noted
above this level.
Sincerely,
Michael E. Anderson, P.E.
