Subject: Lot Line Waiver
Stanley Lot 2
Ladies and Gentlemen:
I am writing to request a lot line waiver for the septic system absorption field at the above
referenced property. The septic system was installed on 7/31 to 8/8/10. The inspection report
stated that the existing trench was 10 feet from the nearest lot line. A surveyed property as-built
located the trench monitor 3 feet from the south property line. The property to the south is a
MOA platted road right-of-way. The system has operated in its current configuration for 1 year
with no negative consequences to the neighboring property. The current configuration of this
septic system will not prevent wells and septic systems from being installed on the adjacent lots.
If you have any questions or concerns, please contact me at 279-3916.
Sincerely,
Civil Engineer

Septic System Installation Permit
Ladies and Gentlemen:
I am writing to request a permit for the installation of a well and septic system for the above
referenced property. The proposed system will serve a 4-bedroom single-family residence.
loga, design calculations, a site plan, design drawings and construction specifications are
enclosed for your review.
Soil
Design Calcs:
Groundwater observed at depth of 4 feet below ground surface
Soil Rating: From Testhole 5/26/2010
12 rain~in = O. 8 gal per sq.fi/day
No. of Bedrooms 4
Required Area per Bedroom: 150/0.8 =187.5 sq.fi.
Total area required: 187.5 x 4 = 750 sqfi
System: We are proposing a 1250 gallon septic tank, and a bed absorption field. The
absorption field will be 50 feet long and 15 feet wide with 0.5 feet (750 sq.ft, effective) of sewer
rock. The buried organic layer will be removed and a minimum of 2 feet of filter sand will be
installed to maintain adequate separation from ground water.
Soils: Two test holes were excaVated on May 26, 2010 under the supervision of Jamie Keller.
See the attached soil logs. Ground water was monitored for through June 22, 2010. Ground
water was observed at 4 feet below the ground surface (bgs). A percolation test was conducted
above the layer of organics in a silty soil. A percolation rate of 12 min/in was observed (TH#l).
The silty sandy, gravel at a depth of 1-4 feet percolated at a rate of 3.1 minutes to the inch.

There are no surface waters within one hundred feet of the proposed septic
Topography: The general topography in the area of the septic system is level. The ground
surface to the east of the proposed septic system rises at a slope of approximately 20%. There are
no man made or natural cut slopes within 50 feet of the proposed septic system.
Waivers: None Required.
The installation of this septic system will not prevent wells and septic systems from being
installed on the adjacent lots. The proposed septic system will not change the general slope of
the area. Ponding and/or concentration of surface runoff will not result from this installation.
If you have any questions or concerns, please contact me at 279-3916.

water wells. Additional separation distances must also be maintained.
The contractor shall remove or abandon the existing tank in compliance with the Uniform
Plumbing Code.
Drain field Construction:
1. The drain field shall be excavated to the dimensions outlined in the design drawings.
any discrepancies are noted, contact the engineer immediately for clarification.
2. The drain field shall be installed parallel to slope contours.
3. The bottom of the drain field shall be within 2" of level. If the sidewalls or bottom of the
excavation become smeared, they must be raked or scarified prior to the placement of
filter sand or drain rock.
4. The drain field must be a minimum of 5 feet from the test hole excavation.
5. Distribution pipe is to be installed level with perforations facing downward, atop a level
bed of drain field rock. Septic rock shall then be placed atop the distribution piping to

inspections must be conducted under the supervision of a Professional Engineer licensed
to practice in the State of Alaska.
The first inspection must be conducted after the excavation of the drain field and before

Water Well Advisory
Certificate of On-Site Systems Approval (COSA) # 111323
During a recent COSA on-site inspection and test of the potable water
supply well on Block , Lot 2 of Stanley subdivision, the well's
productivity was determined to be 0.75 gallons per minute. The minimum
well productivity required by this Department (AMC 15.55) for a 4-bedroom
residence is 0.41 gallons per minute. Although the subject well currently
exceeds this minimum requirement, all parties concerned are advised that the
production capacity of the well may fluctuate. Restriction of non-critical
water uses such as washing cars and watering lawns and gardens may be
required.
This advisory must be attached to all copies of the subject Certificate of On-
Site Systems Approval.
