Dear On Site Services Engineer:
We hereby apply for a permit to construct a septic system on Lot 92B,
Harol Stef Subdivision. The well currently in place on the lot will serve
two houses and will be classified Class C with the respective 150'
protective radius. The attached site plan and backup documentation
identify the location, size and components of the new septic system
proposed to serve the 3 bedroom house on the lot. Testholes placed in the
area of the proposed absorption trench revealed a silty gravel with a
percolation rate of 15 minutes per inch. Groundwater was noted at 12'
below the surface in Testhole No. 1 and continued at that elevation during
the monitoring period. No water was noted at any time in Testhole No. 2.
A wide absorption trench is proposed near Testhole No. 2 with the
distribution pipe placed at 3' below the surface. Four foot of drainfield
rock will be placed below the pipe. The total depth of the system will be
7' providing the necessary separation from groundwater.
A Class C Well is present to the east of this lot and the septic system
will be constructed outside the 150' protective radius. All other
separation distances will also be maintained.
The surface of the lot has a high area near the middle where the house
will be placed. The ground slopes at nearly a 4% slope in both directions
from the high point. Drainage patterns currently present on the lot will
be maintained after construction.
Lot 92B, Harol Stef Subdivision

If the system is constructed as designed the following statements can be
made:
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,
impact on reserved space, either surface
located in the area.
will have no adverse

The system, if constructed as designed, will have no adverse impact
on drainage patterns in the area. The current drainage 3attern will
be maintained.

Waiver Request #WR970053, PID #051-151-40, HA970416
Dear Mr. Anderson:
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 4 feet from the absorption
field to the southern 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.

Lot Line Waiver Request
Dear On Site Services Engineer:
The attached Site Plan shows the location of the recently constructed
septic system on the subject lot. The east end of the absorption trench
encroaches within 4' of the southern lot line. We are therefore requesting
a waiver allowing the trench to be within 4' of the lot line.
No easements exist along the property line where the new trench is
constructed, in addition, no development falls within 50' of the adjoining
property to the south. Soils encountered in the trench are a silty gravel
with a precolation rate of 15 minutes per inch. A significant amount of
usable area is available on the adjacent lot for future septic system
upgrades if necessary. The placement of the absorption trench within 4'
of the lot line will have no' adverse affect on either Lot 92B or the
adjacent lot. We therefore recommend the lot line waiver be issued.
Please let me know if you have additional questions.
Sincerely,
Michael E. Anderson, P.E.

RECEIVED
SEP 22 1997
Municipality of Anchorage
Dept. Health & Human Services
Testhole No. 2 located near the new septic tank and shown on the as-built plan for Lot
92B, Harolstef Subdivision was recently extended to a depth of 20'. This was done as a
result of your review of the system as-built and your onsite meeting with Paul Myers of
MM&M Contracting on Thursday, September 18. No groundwater was encountered
during the excavation nor was any bedrock found. We have therefore verified the absence
of bedrock within 6' of the bottom of the absorption trench. We have also verified no
groundwater within 4' of the bottom of the trench. The attached soils log, signed by Mr.
Myers indicates the deepening of the testhole. We hope this will satisfy your requirements.
The Class C Well on the lot should be certified by ADEC this week. We will forward the
Public Water System Number to you when it becomes available. We are attempting to
complete the Health Authority Certification for the well and septic system on the lot this
week. We appreciate your assistance.
