Comment Sheets
Joe & Jeff,
This is in reply to the three comment sheets. The steepest slope was measured downslope of the
constructed trench & the replacement trench. Analysis was conducted in accordance with the
4/17/04 guidance by James Cross, PE. A profile was drawn with the existing ground slope, the
25% slope line and a line intersecting a point 2.5' above the system extended to the existing
ground at a 35' distance.
The Tablelands, B4 L7: The existing ground dips over 25% at a distance of 15'to 29' from the
replacement trench. The overall slope stays above the 25% line. The slope of the line 2.5' above
the system is @17%.
The Tablelands, B4 L12: The existing ground dips over 25% at a distance of 25' from the
replacement trench. The overall slope dips below the 25% line at a distance of 30' from the
replacement trench. The slope of the line 2.5' above the system is @ 21%.
The Tablelands, B5 Ll: The existing ground dips over 25% at a distance of 22' from the
constructed trench. At this distance a cut -bank is present. This cut -bank requires grading to less
than a 25% slope. Spinell Homes Inc. requests that a conditional approval be granted in order for
the work to be completed next construction season.

RE: Tablelands, Block 5, Lot 1
A lot is being developed. The soil test was good. Groundwater was monitored during the
high water month of May and is not present. A conservative design has been completed,
similar to other lots along this ridge line.
The neighboring lots are mostly developed. This site should not negatively impact any of
the other area lots. The lot slope is relatively flat and drops off in the rear of the lot. A
large greenbelt is present in the back of the lot.
Please review the wastewater system design for the single family home. I have included
design plans & specs, design guidelines, & soil tests. If there is need for additional
information or clarification please give me a call.
Sincerely
Steve Eng, PE, PH5

SPECIFICATIONS & DESIGN GUIDELINES
Wastewater System Sizing: This is a new 4 -bedroom, single family home. Most of the
neighboring lots are developed. Groundwater was monitored during the high time of the
year was not present. A conventional septic system is designed similar to other designs
along this ridge line. This lot is over 1 acre in size and no adverse impacts are expected
from development. The neighboring lots are similar. The lots are served by a public
water system. No conflicts to the other lots will take place by this septic system
construction. The easements are located on the drawing and are not encroached upon.
Soil tests revealed silty sandy soil. An application rate of 1 GPD/FT2 with 0.5 reduction
factor for utilizing a 5' wide trench. Trench Length = 600 FT'/5'x .5 reduction factor =
60'; 1 line @ 60'. No bedrock was encountered.
Specification Requirements: All components and work must comply with the Municipality
of Anchorage Specifications (AMC) & State of Alaska Drinking Water Regulations and
Wastewater Regulations.
• Two compartment, 1250 gallon septic tank. Watertight couplings on inlet & outlet.
• 5' minimum between the tank and bed. 10' to property lines.
• 3' of cover or insulation is required for trench; an equivalent of I" insulation for each foot
soil cover.
• Tank & solid pipe must be set on well compacted, stable soil.
• 4 inch diameter cleanouts with airtight caps are required 1' to 4' from foundation wall, prior
to any 90 degree bend in 4 inch line, in each tank compartment, and two adjacent opposing
cleanouts between the tank and the absorption field, not more than 10' from the tank
positioned to provide cleanout access towards the tank and towards the absorption field.
• All cleanouts must extend to at least ground level.
• In solid pipe runs, ASTM D-3034 may be used in lieu of cast iron.
• Trench to be placed level, minimum of 4' to groundwater, 6' to bedrock from drain -rock.
• Drain rock to be %= inch to 2 %x inch screened. Drain rock to be distributed uniformly
throughout the trench.
• Perforated pipe to be installed level with perforations down.
• Silt barrier (filter fabric) to be installed above the drain rock.
• Smeared trench sides must be raked or scarified before drain rock placement.
• Backfill over drain rock must not be less than 36".
• The finish grade must be mounded to promote drainage over the trench.
• Insulation must be placed over any pipe installed under driveways or parking areas.
• Approved pipe materials include cast iron, PVC ASTM D3034, PVC ASTM F789, ABS
ASTM D2661,
• Sewer Service Line is minimum 2% slope.
• Septic Tank to be pumped every two years or when required.
• Insulation board to be extruded direct burial polystyrene (Dow Styrofoam FII or equal)

F. ENGINEER’S COMMENTS
G. CERTIFICATION & STATEMENT OF INSPECTION BY ENGINEER
As certified by my seal affixed hereto and as of the validation date shown below, I verify that my investigation, based
on procedures outlined in the Certificate of On-Site Systems Approval Guidelines, indicates that the on-site water
supply and/or wastewater disposal system appears to comply with applicable Municipal and State codes,
ordinances, and regulations in effect at the time of installation, unless noted otherwise.
Name of Firm FIRST WATER CONSULTING Phone 907-350-9566
Engineer’s Printed Name CURTIS HUFFMAN, PE Date 4/3/2023
Comments: This investigation was completed in compliance with MOA guidelines, regulations,
and best industry practices / methods. The assessment of the condition of the well and septic
applies only to the conditions as of the day tested. The flow and absorption rates may change
due to subsurface conditions that may not be observed from the surface, changes in land use,
local soil characteristics, groundwater levels that may fluctuate during the year, quality of
construction (workmanship & materials), the water usage of the family being served by the
system and maintenance. The operational life of all well and septic systems are subject to
these various and dynamic characteristics and are outside the control of the evaluator of the
well and septic system. Therefore, any or NO estimate of how long a system will function satisfactory
for current or future occupants or guarantee that no unseen encroachments, deficiencies or
discrepancies exist can be given by First Water Consulting &
