The subject permit, issued 6/11/98 by tiffs office for a single family well and/or on-site
wastewater system, has expired as of 6/11/99.
If you have drilled the well, a well log must be sent to tiffs office for documentation of the
installation and to close the permit.
If a licensed Professional Engineer has inspected the installation of the on-site wastewater
system, the original as-built inspection report must be sent to tiffs office for review,
approval and documentation. All inspection reports must be submitted within 30 days of
construction completion.
A new permit must be obtained from tiffs office for a well and/or on-site wastewater
system NOT installed by the expiration date.
When applying for a new permit, the fees are: $320.00 for an on-site wastewater pe~2nit
and $120.00 for a well permit.

Lot 5, Nettleton Acres Subdivision
Septic System Design
Impacts to Adjacent Properties
Dear Onsite Services Engineer:
The owner of Lot 5, Nettleton Acres Subdivision intends to construct a 4
bedroom home on the lot. We are therefore applying for a permit to
construct a well and septic system on the lot to serve the house. The
attached site plan and backup documentation identify the size and location
of the new absorption bed to serve the home. It also shows the proposed
location of the well and the 100' protective radius. The property
surrounding the lot is currently undeveloped and no conflicts are evident.
A testhole was placed on the lot by S&S Engineers in March of 1992,
during the subdivision phase of the property which revealed silty gravel
with a percolation rate of 27 minutes per inch. This hole, however, was
placed within the 100' setback from the drainage easement. Additional
testholes were placed last Spring by Jeff Garness which revealed percable
soils, but substantial groundwater. Sinced that time the owner of the
property has installed a french drain and improved the drainage on the
property. A testhole placed in late May showed no groundwater indicating
the french drain is apparently controlling the flow. The absorption trench
has been designed for placement in the area of no groundwater.
We have used a composite absorption rate to design the trench based on
materials encountered. The top 3' of the trench is gravelly material with
a percolation rate under 5 minutes per inch. The next 5' of the trench is a
silty sand with a percolation rate of 60 minutes per inch. The silty sand
is underlain by a poorly graded sand which percolates under 5 minutes per
inch. We have used a composite rate of .6 gallons per day per square foot
Lot 10, Block 2, Park Hills
June 2, 1998
Page Two
to design the trench. This rate is conservative since half the trench will
be in soils with an absorption rate of 1.2 gallons per day per square inch.
The surface of the lot slopes from east to west at a gradual rate which
increases radically toward Hillside Drive. The area is fairly flat in the
area of the proposed absorption trench.
If the system is constructed as designed 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 reserved 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.

ON-SITE WASTEWATER DISPOSAL SYSTEM
CONSTRUCTION AND MATERIAL SPECIFICATIONS
SUBJECT: LOT 5, NETTLETON ACRES SUBDIVISION
GENERAL:
1. The scope of this project includes the procurement and
placement of a new 1,250 gallon septic tank. It also
includes the construction of a new 50' long by 3' wide by

on the site plan. Fill will be required over the trench to
provide a minimum of 3' of cover.
2. Construction shall be in accordance with the approved site
plan, design drawings, Municipal Permit with any special
provisions or conditions, and all applicable State and
Municipal Wastewater Disposal Regulations.
3. The Contractor shall be responsible for obtaining all
underground utility locates and for the layout of the septic
system and verification of the location of all lot lines.
4. Unless specifically agreed otherwise, the contractor shall
be responsible for final grading areas subsequently
depressed from soil settling. Property owner shall be
responsible for revegetation of affected areas unless
specifically agreed otherwise.
5. Contractors installing wastewater disposal systems must
be certified by the Municipal Department of Health and
Human Services for system installations. Owners installing
their own systems must receive prior approval from D.H.I--I.S.
before beginning system installation.
SEPTIC TANK INSTALLATION
A new 1,250 gallon septic tank must be procured from an
approved source and installed at the location shown.
Lot 5, Nettleton Acres
June 3, 1998
Page Two
2. A septic tank is to be constructed by a certified septic tank
manufacturer. Construction shall include two 4" cleanouts
for pumping access.
3. The septic tank shall be sufficiently bedded to prevent
settling or shifting of the tank.
4. All standpipes on the septic tank shall extend a minimum of
12 inches above final grade.
5. Tanks installed without 4' of cover shall have a minimum of
2" of direct burial insulation.
6. A foundation cleanout shall be installed one to four feet
from the building foundation. Two cleanouts are required
between the tank and the drainfield.
7. Final grading over the tank shall be such that a positive
slope exists away from the septic tank.
DRAINFIELD CONSTRUCTION:
1. The drainfield shall be constructed to the dimensions shown
on the design. The bottom of the trench shall be within 2"
of level.
2. Distribution piping must be placed level with perforations
down atop a level bed of drainfield rock. Rock should then
be placed over the pipe to provide a minimum of 2" of cover.
3. A silt barrier or geotextile fabric must be placed between
the drainfield rock and the natural soil backfill.
4. Monitor tubes must be 4" in diameter and installed at the
locations shown on the design. The portion below ground
must be perforated.
Lot 5, Nettleton Acres
June 3, 1998

5. Contractor shall verify the septic tank and drainfield are a
minimum 100' away from any private water wells in the
area, 150' from a Class "C" Well or 200' from any community
well.
6. Direct bury insulation must be placed over the distribution
system if less than 3' of backfill depth is available. Finish
grade over the trench must be mounded to prevent
settlement or depressions.
7. Grade area surrounding the absorption trenches to drain
away.
8. A minimum 2' of accepting soil is required below the
drainfield rock for a 5' wide trench. Contractor shall verify
this condition prior to placement of the rock. All pockets of
unacceptable materials must be removed and replaced.
MATERIAl.. SPECIFICATIONS:
1. Septic tanks must be constructed by a Municipally approved
septic tank manufacturer.
2. The following pipe materials are approved for use in septic
system installations in the Municipality of Anchorage:
Cast Iron (perforated and solid), ASTM D3034 or P.V.C.
(perforated and solid), ASTM F810 or H.D.P.E. (perforated,
but not solid) and ASTM D2662 or A.B.S. (perforated and
