The department supports the reduction of housing
density as proposed in this resubdivision of the
existing Cromwell Heights. However, resubdlviding
subjects this plat to the-same requirements as for
new development. Therefore, the following items
are required bY DHHS prior to preliminary plat
approval, as outlined in AMC 15.65.40, .60, and
.180, and AMC 21'.15.110:
1. Show'all existing sewer systems and wells on
property and within 200 feet of property.
~/2. Provide documentation of existing sewer
system on Lot lA, including appropriate soils
information.
~/~. Provide information on water availability for
this subdivision.
~. Show all surface water sources which cross
this property. Show any subsurface drains on
the property.
,~. Provide adequate soil testing on each lot.
Applicant must show that each lot has
sufficient area for one original and two
replacement wastewater disposal sites.
Due to the lack of information, DHHS is unable to
support this plat. We recommend it be returned to
the developer for additional information. Should
it be submitted to the board, we recommend the
plat be denied.

Subject: Lots A & B, Block 2, Cromwell Hts. Sub.
Gentlemen:
In November of 1990 and again on April 18, 1991, test pits were dug
on what are currently platted as Lots 3, 4, 5, & 6 of Block 2, Cromwell
Heights Subdivision. The purpose of the exploration was to
determine if underlying soils were suitable to support onsite waste
disposal systems with the intention of replatting the lots into 2
buildable lots. A total of six test pits were dug to ascertain the
suitability of the soils.
A drainage swale traverses Lots 3 and 4, therefore a septic system
for the proposed merged lot must be located a minimum of 10ft from
the swale. This severely limits the surface area available for the
onsite system. Testhole No. 2 initially excavated and tested in
November' reveals suitable soils for the system. A soils log and
percolation test for this testhole is included for your use. Testhole
No. 5 revealed tight silty soils which will percolate at a very slow
rate and much less suitable for the onsite system than Testhole No. 2.
No groundwater was either in either hole during initial excavation or
after monitoring periods of at least seven days. Testhole No. 4
revealed clean gravel at a depth 2' below the surface. The gravel
lense was overlain with thick organic material. This testhole appears
susceptible to groundwater intrusion during spring runoff, however,
and may not be acceptable for a septic system.
The area surrounding Testhole No. 2 is obviously the best site for the
onsite system for the proposed merged lot. The percolation rate for
the soils in this area is 15 minutes per inch resulting in a necessary
drainage area of 190 square feet per bedroom. A system placed
between 4' and 10' below ground surface would require a 15' length
of leach field per bedroom for any home placed on this lot.
Robert G. Palmer & Associates
April 24, 1991
Page Two
Testholes No. 1 and 3 were nearly identical
Testhole No. 2. The percolation rates for these soils was similarly 15
minutes per inch and the drainfield requirements for soils in this
area are also 190 square feet per bedroom. The test results for
Testhole No. 1 are included for your use.
Both proposed lots require a reserve area of 14,000 square feet for
the septic system. The attached site plan indicates the reserve
requirement is easily attained on each lot. In summation, it appears
both lots will support onsite septic systems if they are installed in
the locations recommended. Please advise if you need further
information.
Sincerely,
Michael E. Anderson, P.E.

Attention: Susan Oswalt
Subject: Lots 3A & 4A, Block 2, Cromwell Hts. Sub.
Dear Susan:
Attached is the revised site plan and three individual septic system
designs to serve proposed Lot 4A of Block 2, Cromwell Heights
Subdivision. This plan differs from the original in that the 4A
systems are designed for a four bedroom home rather than three.
Soil conditions are such and sufficient space available that the
systems will adequately serve a four bedroom home. Lot 3A
remains the same and will serve only a three bedroom home.
Hopefully the plat note will now limit Lot 3A to three bedrooms and
Lot 4A to four bedrooms. Please advise if you need additional
information.
Sincerely,
Michael E. Anderson, P.E.

Attention: Susan Oswalt
Reference: Lots 3A & 4A, Block 2, Cromwell Hts. Sub.
Dear Susan:
Attached is the site plan and six individual septic system designs to
serve the two lots proposed for Cromwell Heights Subdivision. All
systems are 5' wide, shallow trench designs. Three will require
insulation as the water table is 8' below the surface and will limit the
depth of bury of the drainfield lines. The remaining three systems
will not require insulation as the water table is not evident or deep
enough to allow sufficient burial depth. Well locations are shown on
the site plan to indicate the required separation distance from the
septic systems.
Monitor tubes remain in the ground on the site for your inspection. I
will be available for an onsite inspection if required. Please advise if
additional information is required to obtain approval of this
subdivision.
Sincerely,
Michael E. Anderson, P.E.

Subject: Lots 3A and 4A, Block2, Cromwell Hts. Sub.
Dear Mr. McBride:
On June 28, 1991, we conducted a soils investigation on Lot 3A of
Block 2, Cromwell Heights Subdivision. The purpose of the
investigation was to locate suitable soils for an onsite septic system
to serve the lot if the southern end of the lot line was moved 60' east
to its original location rriaking it parallel with the eastern lot line.
Several test holes had been dug previously on this lot to also
determine suitable soils.
Lot 3A is traversed by a drainage swale severely limiting the area
available for an onsite system. Further complicating the problem are
high groundwater conditions throughout the lot. Testhole No. 6
revealed gravelly sandy soils beneath the peat layer with the initial
excavation remaining dry. After the 7 day monitoring period,
however, the water level was within 5' of the surface. This area is
acceptable for an engineered mound type system, but the system
would require a lift station and additional engineering and would be
much more expensive than a standard system.
Testholes No. 7, 8 and 9 revealed clean, well graded gravelly soils
immediately below the 1' to 2' peat layer. The water table in these
areas was found between 3' and 5' of the surface. These areas may
also be acceptable for a mound type system, but additional water
monitoring should be considered. Water monitoring throughout the
year may reveal the groundwater rising to the bottom of the peat
layer totally saturating the gravel material.
The explorations indicate Lot 3A is underlain by a clean, well graded
gravel which is ideal for an onsite system. This is further evidenced
by the ditching or driveway construction that was accomplished on
the lot which reveals the gravelly lens to be nearly 10' deep beneath
the top organic layer. It is essential, however, the groundwater level
on the lot be controlled so a septic system could operate adequately.
A curtain drain placed along the back lot line would accomplish this

objective and should work well with the terrain of the lot. If the
water table was lowered to 8' below the surface a bed type system
could be placed almost anywhere in the system reserve area on Lot
3A. Lot 4A appears to be unaffected by the high groundwater
conditions in the areas where the testholes were located on previous
explorations. ,
Testhole data is included for your use along with a site map which
delineates the reserve area required for each lot and shows the
testhole locations. Please advise if further information is required.
Sincerely,
Michael E. Anderson, P.E.

Attention: Mary Reardon
Subject:
Lots 1 & 2 Cromwell Heights Subdivision
Well Production & Septic System Adequacy Tests
Dear Mary:
On Saturday, December 8, 1.990, I inspected and tested the onsite
utility systems serving the house located on Lots 1 & 2 of Block 2 of
Cromwell Heights Subdivision.
An outside faucet was turned on full and the well run for a total of
four hours to determine whether sufficient flow was available to
meet Municipal standards. Initially, the well flowed at a rate of 2.5
gallons per minute and continued at this rate for nearly three hours.
At the end of the fourth hour the flow was measured at 2.25 gallons
per minute. This compares very favorably with the Municipal
requirement of .104 gallons per minute per bedroom. As a result of
this test we can conclude the well is performing' in an acceptable
manner and providing sufficient water for normal habitation.
A water sample was taken from the outside tap to determine the
fecal coliform bacteria and the nitrate content. The sample was
analyzed by the Chemical and Geological Laboratories of Alaska and
found to be satisfactory for human consumption. A copy of the
laboratory results is attached for your use.
The cap on the well must be removed and a sanitary cap installed.
In addition, the wiring from the well head into the house must be
encased in conduit to prevent contamination to the well and to
eliminate a possible safety hazard. These items should be remedied
before the house is again occupied.
The septic tank was inspected from the surface only and appears to
be functioning properly. The size of the tank was not determined.
The previous owner has indicated the tank has a capacity of 1,200
gallons. The Municipality requires a capacity of 1,000 gallons for

houses with two bedrooms. The tank is separated from the well by a
distance of 85'. This does not meet the Municipal requirement of
100', but since the system was installed prior to this requirement,
the separation distance is waived until a system upgrade is required.
Nearly 600 gallons of water was pumped into the crib type
absorption system to determine whether it was functioning properly.
The system is expected to absorb 150 gallons of fluid per bedroom
per day to be considered functioning properly. Prior to pumping the
water into the crib no water was present and the depth of the crib
was determined to be 8.5 feet. The 600 gallons Of water filled the
crib to within a foot of the surface. The following day the water level
had dropped to within 5 feet of the surface. Two days later the crib
was again dry. This .indicates the crib is capable of absorbing the
300 gallons per day as required by the Municipality. We can,
therefore, conclude the septic system is operating in an acceptable
manner at the present time.
The Municipality will not aUthorize Health Authority Approval on the
crib unless a test hole is dug to a depth 4' below the crib bottom to
show minimum separation from ground water. Municipal regulations
state a septic system must maintain a 4 foot vertical separation from
the seasonally high groundwater level. Since the crib is dry now we
know the groundwater is at least 8.5 feet below ground level. Unless
a test hole is dug, however, we cannot say with certainty the ground
water level is more than 12.5 feet below ground. Once the water
level is verified and the sanitary seal and conduit are placed on the
well, the Municipality will grant Health Authority Approval to the
system serving this house.

Michael E. Anderson, P.E.
