Subject: Lot 12, Block 1, Forest Ridge Subdivision
Septic System Design and Permit Application
Impacts to Adjacent Properties
Dear Onsite Services Engineer:
The owner of Lot 12, Block 1 , Forest Ridge Subdivision intends to construct a new two-
bedroom ADU on the lot. The existing house and septic system was constructed in
2013 and the septic system absorption trenches will be extended to accommodate the
new ADU. We are therefore requesting a permit be issued for the reconstruction of the
existing septic system to accommodate the total 6 bedroom count once the ADU is
operational. The attached Site Plan and backup documentation identify the location and
configuration of the existing well and septic system along with the alternate site. Also
identified on the plans are the existing wells and septic systems on surrounding lots. No
conflicts exist between the proposed extension to the septic system and wells or septic
systems on adjacent lots. Drainage arrows are shown on the site plan showing the
grade and direction of flow on the lot. The drainage pattern will not be changed as a
result of this project.
Two test holes were placed on the lot in the area of the absorption trench and alternate
site. The logs indicate silty sand (SM) in the zone specified for the absorption trench
extensions. The percolation rate of the soil was determined to be 4-5 minutes per inch.
No groundwater was found during the placement of the test holes but was noted during
the monitoring period at 7.5' to 14' below the surface. An application rate of 1.2 gallons
per day per square foot was used in the design of the absorption system. We are
proposing to place a new 1 ,250-gallon STEP tank at the ADU and extend the existing 2
- 35' long by 5' wide by 2' effective depth absorption trenches a total of 18' each to treat
and dispose of the effluent generated in the house and ADU. The elevation of the
distribution line in the absorption trenches will be 1.5' below the surface and the total
depth will be 3.5'. The delivery line from the new STEP tank will intersect the existing
delivery line at the midpoint between the two trenches. A minimum of 3' of fill or 2" of
insulation and 2' of fill will be placed over the absorption trench extensions and 4' over
the STEP tank.
Lot 12, Block 1, Forest Ridge Subdivision
June 14, 2017
Page Two
The ground surface on the lot in the area of the septic system slopes to the north. The
new trench extensions will be constructed parallel with the contours of the slope as
much as possible in conformance with Municipal requirements. The new septic system
will be constructed a minimum of 100' from all wells and any surface water and 10' the
proposed and existing water services in the area.
If the system is constructed in accordance with our design the following statements
apply:
1. 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.
2. 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.
3. The system, if constructed as designed, will have no adverse impact on reserve
space, either surface or subsurface, on any lots located in the area.
4. 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,
E a ei2

MUNICIPALITY OF ANCHORAGE
PLATTING AUTHORITY RESOLUTION NO. 2016-011
ANCHORAGE RECORDING DISTRICT
A RESOLUTION APPROVING AN AMENDMENT TO NOTE 1 ON PLAT 98-29 THAT
PROHIBITS DIRECT VEHICULAR ACCESS TO WOODHAVEN AVENUE FROM LOTS 1B,
11, & 12, BLOCK 1, FOREST RIDGE SUBDIVISION TO ALLOW DRIVEWAY ACCESS TO
WOODHAVEN AVENUE FROM LOT 12, BLOCK 1, FOREST RIDGE SUBDIVISION,
GENERALLY LOCATED SOUTH OF WOODHAVEN AVENUE, NORTH OF BISHOP'S
CASTLE CIRCLE, EAST OF BUFFALO STREET AND WEST OF EVERGREEN STREET
WITHIN THE NE 1/4 OF SECTION 34, T12N, R3W, SEWARD MERIDIAN, ALASKA.
WHEREAS, a petition has been received from Brandon and Sarah Skeel to amend
Note 1 on Plat 98-29 that prohibits direct vehicular access to Woodhaven Avenue from
Lots 1B, 11, & 12, Block 1, Forest Ridge Subdivision, to allow a driveway access to
Woodhaven Avenue from Lot 12, Block 1, Forest Ridge Subdivision, generally located
south of Woodhaven Avenue, north of Bishop's Castle Circle, east of Buffalo Street and
west of Evergreen Street, within the NE 1/4 of Section 34, T12N, R3W, Seward
Meridian, Alaska; and
WHEREAS, notices were published, posted and mailed and a public hearing was
held on November 2nd, 2016.
NOW,THEREFORE, BE IT RESOLVED by the Platting Authority that:
1. The Platting Board makes the following findings of fact:
There will be no significant increase in traffic on Woodhaven Avenue with
the addition of one driveway.
a. Plat notes that restrict access to roads are related to issues of
grade, curvature, or slippery conditions in the winter. Woodhaven
Avenue appears to have a 3% to 4% grade, which will not create a
hazard in winter. The line-of-sight appears to be several hundred
feet given the speed limit of the roadway. The plat note does not
seem to be warranted as the roadway is relatively level with good
visibility. There do not appear to be safety issues that would result
from one additional driveway from the petition site to Woodhaven
Avenue.
eRecorded Document
Platting Authority
Resolution No. 2016-011
Page 2
b. A second driveway access from the accessory dwelling unit to
Bishop's Castle Circle would require a switchback that would be a
significant burden.
c. In response to public testimony, the Board found that there is no
evidence that trailers and recreational vehicles will be stored on the
petition site, although storage of snow machines, trailers and
recreational vehicles on the property is a permitted use in the R-6
(Low Density Residential-1 acre) District.
d. There are four existing driveways from Forest Ridge Subdivision to
Woodhaven Avenue that were constructed without prior approval to
amend the plat note or objection from the residents of the adjacent
subdivision. These driveways have existed for many years without
apparent adverse impact on the surrounding neighborhood.
e. The Board noted that there were two written comments in support
of the amendment to the plat note in the packet and one late
comment laid on the table in support of the request to amend the
plat note.
f. A driveway from Woodhaven Avenue to the accessory dwelling unit
is a reasonable use of the property with negligible impact on the
surrounding neighborhood.
2. The Platting Board APPROVES the amendment to Note 1 on Mat 98-29 to
allow direct vehicular access to Woodhaven Avenue from Lot 12, Block 1,
Forest Ridge Subdivision, subject to the following conditions:
a. The driveway onto Woodhaven Avenue shall be constructed to
municipal driveway standards to include maintaining existing
drainage along the right-of-way.
b. Making the following drafting changes:
i. In the platted area: Evergreen St. should read Evergreen
Ridge St.
ii. In the Vicinity Map: Evergreen St. should read Evergreen
Ridge St.
c. Filing a resolution with the State District Recorder's Office.

Dear Onsite Services Engineer:
The owner of Lot 12, Block 1, Forest Ridge Subdivision intends to construct a new four-
bedroom home on the lot. We are therefore requesting a permit be issued for the
construction of a new well and septic system to accommodate the home. The attached
Site Plan and backup documentation identify the location and configuration of the
proposed well and septic system along with the alternate site. Also identified on the
plans are the existing wells and septic systems on surrounding lots. No conflicts exist
between the proposed septic system and well or septic systems and wells on adjacent

flow on the lot. The drainage pattern will not be changed as a result of this project.
Two test holes were placed on the lot in the area of the absorption trench and alternate
site. The logs indicate silty sand (SM) in the zone specified for the absorption trench.
The percolation rate of the soil was determined to be 4-5 minutes per inch. No
groundwater was found during the placement of the test holes but was noted during the
monitoring period at 7.5' to 14' below the surface. An application rate of 1.2 gallons per
day per square foot was used in the design of the absorption system. We are
proposing to place a new 1,500-gallon STEP tank and 2 - 35' long by 5' wide by 2'
effective depth absorption trenches to treat and dispose of the effluent generated in the
house. The elevation of the distribution line in the. absorption trenches will be 1.5'
below the surface and the total depth will be 3.5'. A minimum of 3' of fill or 2" of
insulation and 2' of fill will be placed over the absorption trench and 4' over the septic
tank.
The ground surface on the lot in the area of the septic system slopes to the northwest.
The new trench will be constructed parallel with the contours of the slope as much as

possible in conformance with Municipal requirements. The new septic system will be
constructed a minimum of 100' from all wells and any surface water and 10' the
proposed and existing water services in the area.
If the system is constructed in accordance with our design 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 reserve
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.
