Dear Sirs:
14530 ECHO ST.
ANCHORAGE, ALASKA 99516
The purpose of this letter is to provide the required design narrative in support of our application for
a permit to construct wastewater disposal facilities on Lot 5B, Block 5, Skyway Park Estates located on
Thomasson Drive. Soils logs, perc test results, a site plan, design drawings and specifications are
enclosed for your review.
The proposed system will be constructed in the vicinity of test hole 4 1. As can be seen from the soil
log, the native material below 5 feet is a silty sandy gravel with a measured perc rate of 3 minutes per
inch. A stabilized groundwater level of 16.5 feet below ground level was observed during May of this
year. Using a somewhat conservative soil application rate of 0.8 gpd/sq. ft., this proposed 4 -bedroom
residence requires a total absorption area of (4 x 150)/0.8 = 750 square feet. The proposed 63 -foot long
design with 6.5 feet of gravel below the distribution pipe (between 5.5 and 12 feet below ground level)
has a total absorption area of 819 square feet.
The topography of the lot in the area of proposed construction is generally level.
The proposed project will have no significant impact on present or future water supply and
wastewater disposal systems serving adjacent properties, nor will it have any significant impact on
reserved space -surface and subsurface, or on drainage.
Please give me a call at 345-1355 if you have any questions on this submittal.
Sincerely,
Ted Moore, P.E.

Wastewater disposal system installation
Specifications
1.0 General:
1.1 The scope of the project consists of installing a 1250 -gallon septic tank that discharges effluent
into a 63 -foot long soil absorption trench containing 6.5 feet of gravel below the horizontal distribution
pipe -
1.2 Construction shall be as depicted on the approved site plan and design drawings. Minor
deviations from these drawings may be allowed or required by the engineer conducting the inspections.
All construction procedures and material specifications shall conform to Municipal and State
requirements. All separation distances shall be in conformance with Municipal requirements, unless
specifically waived.
1.3 The contractor shall be responsible to obtain any necessary utility locates, and to work around
any buried utilities.
1.4 The contractor shall provide adequate cover material and rough grading over all system
components to ensure that proper drainage is achieved after settlement and that there are no residual
depressions. Insofar as possible the contractor shall minimize damage to trees and existing lawn areas.
1.5 Unless specifically agreed otherwise, the homeowner shall be responsible for finish grading
after the soil is compacted, as well as placement of topsoil and reseeding all areas disturbed by the
construction.
2.0 Septic Tank:
2.1 The new 1250 -gallon, 2 compartment septic tank shall be Municipally approved and shall be set
level on undisturbed soil. Each compartment shall be equipped with a watertight manhole cover and a
4" cleanout. If the tank is buried less than 4 feet, it shall be insulated with 2 inches of approved burial
type, rigid insulation.
2.2 All pipe connections to the tank shall be equipped with waterproof mechanical couplings. The
waste line from the residence to the septic tank shall have a minimum slope of 1/4"' per foot, and the
waste line between the tank and the soil absorption system shall have a minimum slope of 1/8" per foot.
A cleanout shall be installed 1 - 4 feet from the building foundation, and a double cleanout shall be
installed within 5 feet downstream of the septic tank.
3.0 Soil absorption system:
3.1 The soil absorption system shall be constructed by excavating a 63 -foot long trench to a depth of
12 feet below ground level. The long axis of the excavation shall parallel an existing contour
3.2 The bottom of the excavation shall be level. Any compacted or smeared surfaces shall be raked
to allow proper infiltration. Sand for leveling or serving as filter material shall comply with Municipal
specifications.
3.3 A total of 7.0 feet of approved sewer gravel shall be placed in the bottom of the excavation with
the perforated distribution pipes laid level such that the pipe inverts are no less than 6.5 feet above the
bottom of the sewer gravel. Sewer gravel shall be 0.5" - 2.5" screened gravel, with less than 3% passing
the #200 sieve.
3.4 Monitor tubes and cleanout pipes shall be of 4" diameter and installed in the locations shown on
the design drawings. The portion of the monitor tube extending through the sewer gravel shall be
perforated.
3.5 Approved filter fabric shall be placed over the entire top surface of the sewer gravel. A
minimum of 2 feet of soil cover is to be placed over the filter fabric. If the soil cover thickness is less
than 3 feet, two inches of rigid, burial type insulation is to be placed over the entire top surface of the
gravel, in addition to the filter fabric.
3.6 The top surface of the cover material shall be raised a minimum of 6 inches higher than the
surrounding terrain to allow for subsequent settlement, and shall be graded to smooth contours. Fill
slopes shall be no steeper than 3:1.
3.7 Unless specifically agreed otherwise the homeowner shall be responsible for arranging to have
the site finish graded atter the backfill material has stabilized, and for placement of adequate topsoil and
seed to promote rapid revegetation of all areas disturbed by the construction.
4.0 Inspections:
4.1 A total of 5 engineering inspections will be required during the course of the project: (1) initial
stakeout with the contractor to establish the location of the system and to discuss the plans,
specifications and construction procedures, (2) after the native material has been excavated to expose the
infiltrative surface to ensure that it is level and at the right elevation, and conforms with the soil test
information, (3) after the sewer gravel is in place and the distribution pipes have been laid and connected
up to the septic tank, but prior to placement of insulation or filter fabric, and (4) after rough backfill and
grading is complete. The septic tank requires one inspection after it is set level and the piping
connected, but prior to backfill. This inspection may be incorporated with any of the above inspections.
4.2 The installer shall coordinate the timing of the inspections with the engineer sufficiently far in
advance to ensure the availability of the engineer.
