Subject: Waiver Request for Lot 7 Block 1 Sky Ranch Estates #2
Waiver Request #WR970049, PID #015-302-18, SW970294
Dear Mr. Moore:
Your request for a waiver of the required 10 foot separation
between an on-site wastewater disposal system and a lot line has
been approved. The waived distance is 3 feet from the leachfield
to the west property line.
This approval applies to the existing on-site wastewater disposal
system lot line separation only. Any future upgrade to the on-site
wastewater disposal system will require all separations be met or
another approval from this department.
If there any further questions or concerns regarding this waiver,
please call our office at 343-4744.
Sincerely,
Civil Engineer

Dear Sirs:
The purpose of this letter is to provide the required design narrative in support of our application for
a permit to upgrade the wastewater disposal facilities on Lot 7, Block 1, Sky Ranch Estates, Unit #2.
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 # 1. As can be seen from the soil
log, the native material between 7 and 15 feet below ground level is a somewhat silty fine sand with. a
measured perc rate of 5 minutes per inch. Using a conservative soil application rate of 0.6 gpd/sq, ft.,
this 3 bedroom residence requires a total absorption area of(3 x 150)/0.6 = 750 square feet. The
proposed 82 foot long trench design with 5 feet of sewer gravel beneath the distribution pipe has a total
absorption area of 820 square feet.
In order to maximize the separation distance from the existing log crib seepage pit a lot line waiver is
requested allowing the soil absorption trench to be located 3 feet fi'om the west property line, common
with Lot 6. Because the lots in this subdivision are served by a community well and the existing septic
system on Lot 6 is approximately 75 feet away, granting the requested waiver will have no significant
effect on the ability to construct replacement systems on Lot 6, when that becomes necessary.
The topography of the lot in the area of the proposed construction is fairly level, with an estimated
2% average slope to the west.
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.

Specifications
1.0 General:
1.1 The scope of the project consists of abandonment of an existing septic tank and log crib seepage
pit and installation of a new 1000 gallon septic tank followed by 82 lineal feet of soil absorption trench
with a total of 5.5 feet of sewer gravel.
1.2 Construction shall be as depicted on the approved site plan and design drawings. Depending on
site conditions, minor deviations from these drawings may be allowed or required by the engineer
conducting the inspections. All construction procedures and material specifications shall conform with
Mmficipal 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.
1.6 The homeowner shall be responsible for arranging to have the storage shed in the area of the
proposed trench temporarily relocated during cons#'uction, and shall also arrange for a land ,~trveyor
to locate the northwest property corner and place stakes marking the north and west property lines at
points 50feet away from the northwest corner.
2.0 Septic Tank:
2.1 The existing septic tank and seepage pit must be properly abandoned by thoroughly pumping,
removing their tops and backfilling with soil. For the septic tank, this may entail temporarily shoring up
the existing deck and/or installing new supports.
2.2 The new 1000 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.
2.3 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 within 5 feet of 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 an 82 foot long trench to a total
depth of 12 feet below original ground level in the vicinity of test hole #1.
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 Mmficipal
specifications.
3.3 A total of 5.5 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 5.0 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 12 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 after 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 Aminimum of 4 engineering inspections will be required during the course ofthe 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.
