Soils Report
Engineering Report
Project Description
This soils report is to identify the suitability of the soils on the lot for an on-site septic system.
The subject lots are the proposed subdivision of CANYON VIEW ESTATES PH2, BLOCK 2, LOTS 8-
11 and TRACT 2A. This report will detail the soils encountered during the soils investigation,
existing topography, impact to surrounding wells and septic system and the suitability of the
soils encountered for the use of an on-site wastewater disposal system and water supply
system. The lots range from approximately 1.53 acres to 11.7 acres in size. The lots are
currently undeveloped.
Soils Investigation
This tract of land has had two very thorough soils investigation performed over the past 30
years. In the summer of 1983, Mr. James Roberts, P.E., R.L.S. performed 24 soils test pits, the
test pit locations are shown on our overall site plan in Appendix A. His report is included in this
report as Appendix B. The location of Mr. Roberts soil test pits are noted on the attached
drawing. Mr. Roberts' test pits verified that there was no bedrock in this area to a depth of 16
to 18 feet below the ground surface. These test pits did included the identification of ground
water static water levels discovered during the excavation of the test pits. Mr. Roberts report
did not include seasonal high ground water levels nor soil percolation tests.
The Municipality of Anchorage expanded the Canyon Road, which bisects this tract of land. The
MOA hired Lounsbury and Assoc., and Shannon & Wilson, Inc. to perform the soils exploration
for the road upgrade. The Soils investigation found similar soils to both James Roberts, P.E. and
what PES found. Additionally, the borings extended to a depth of sixteen and a half feet (16.5')
below the road grade. The borings did not encounter any bedrock. The ground water levels
were monitored in May of 2022 (Season high ground water month) and found the water levels
to be approximately five to ten feet below ground levels, where ground water was found at all.
Some test borings were dry. The MOA soils investigation is contained in Appendix C.
Pannone Engineering Services performed a soils investigation on October 2, 2019 through
October 11, 2019 throughout the proposed subdivision. The intent of the investigation was to
verify the percolation rate of the soils and to obtain seasonal high ground water levels. The
verification of bedrock depth greater than 16 feet was verified by Mr. James Roberts, P.E., R.L.
S. The test pits were excavated by White Raven excavation using a Komatsu 160 track
excavator, and were excavated to the maximum extent of the excavator or until refusal. On
October 6, 2020 through October 8, 2020 Pannone Engineering Services performed additional
soils investigations, verifying the lack of bedrock to 16 feet in each of the 2019 test holes, and
performed additional soils investigations to verify the percolation rate of the soils and obtain
seasonal high ground water levels in additional locations due to reconfigured lot lines in the
proposed subdivision. The test pits revealed a variety of soils as shown on the attached Soils
Logs for each of the proposed subdivision lots. Water monitoring was conducted on all 33 test
holes on October 11, 2019. Additional water monitoring was performed in May of 2020.

Soils Report
Groundwater was monitored on the new test holes on October 28, 2020. Finally two additional
test holes were excavated on May 21, 2022 due to lot lines moved for Phase 2 and groundwater
monitoring was performed on May 28, 2022
Topography
The proposed subdivision is characterized as sloping terrain and is on the north side of a
mountain valley. In general, the entire area starts sloping down from the northeast to the
southwest (see attached subdivision site plan). There is a gently sloping bench, adjacent to
both sides of Canyon Drive that provides an excellent area for home sites without requiring
large cuts or fills that are typical of steeper hillside lots.
Existing water and wastewater systems
The Phase 2 lots are currently undeveloped. There are developed lots to the northwest of the
proposed Phase 1 lots. Phase 2 also has developed lots to the east. The existing water supply
systems are private wells and have a 100 -foot protective radius around them (i.e. a new
wastewater disposal system may not be located less than 100 feet from these private water
wells.) The documented wells are far enough back on the lot that their protective well radiuses
do not affect the proposed subdivision lots. The surrounding properties also do not exhibit
shallow bedrock conditions, further proving the viability of this subdivision and that bedrock
depth is not a concern.
Surface water
Rabbit Creek runs from east to west to the south of the proposed lots. On Phase 2 there are
ephemeral drainage ditches on Block 2, lots 10 & 11, and Tract 2A. All required separation
distances have been observed.
Engineering Criteria
For Phase 2 PES conducted six percolation tests on the proposed lots and found a percolation
rate varying from less than one minute per inch (<1.0 mpi) to over one hundred twenty minutes
per inch (120mpi).
Based upon the soil test results there are several optio s for systems that could be installed on
all of the lots with the exception ofBlock Lot 1, and ract 1 hat wil_ I require platted AWWTS
instal included in the desi n ac et . However, additional testhole and soils investigation
have the potential to find more suitable soils on these proposed lots, at a later time. There are
no steep areas within the respective reserve areas.

Site Information
The Municipality of Anchorage (MOA) Regulations (15.65) govern for single-family homes.
These regulations require a minimum of four (4) feet vertical separation between the bottom of
a soil absorption .system and groundwater for a conventional wastewater disposal system, six
feet (6') to bedrock or other impermeable layers (tight silts and clays) and must be located
greater than 100 feet horizontally from any surface water (Creeks and ponds). Additionally, the
accepting soils must have a percolation rate of less than 120 minutes per inch. A lot must have
room for a primary and reserve soil absorption system. Advanced treatments systems have
been approved for use by the MOA and have approval for much smaller separation distances
than conventional systems. Advanced treatment systems are an option for development of any
of these lots as well.
Water Availability
Based upon surrounding lots in the subdivision there is availability for a private water system
on the proposed lots. A survey of the well data from the surrounding lots is provided on the
table below. Data shows ample water availability in the lots surrounding the above referenced
lot. A majority of the wells in other sections of the subdivision are bedrock wells with a depth
to bedrock ranging from 70-150 feet. Further reducing any concerns for shallow bedrock within
this development or the surrounding areas. No major geologic changes to the area have
occurred to affect the existing aquafers since well before settlement of the Anchorage area and
tend to happen over larger time -spans than are of concern to this subdivision. Earthquake
related changes to individual fissures that have an effect on individual wells cannot be
predicted in the same way as a whole aquafer. When you look at historical well driller logs vs
COSA well adequacy test results the adequacy test generally shows a lower production because
the maximum flow that can be tested for a COSA is the rate that the pump can produce, not the
high rate that a well driller can pump and prove that the well is capable of producing as shown
on the well log. AMC 15.55 requires a report that indicates there is sufficient water available.
Based on the neighboring subdivisions, there is sufficient water available. There are relatively
Canyon View Estates, Phase 2, Block, Lots 8-11 and Tract 2A May 31, 2022
Soils Report
few areas in the municipality with any type of limited water availability. This is not one of those
areas. This subdivision is located at the top of the ground water area, and there are no
additional subdivisions above this proposed subdivision. To emphasize this we have included
several additional well logs located on the same geologic bench area further than the required
250 -feet.
