Approval of the plat subject to:
1. Resolving utility easements. (Note: The returned comment from
CEA is requesting a 10 -foot T&E easement along the south
property boundary, which is a different configuration as shown on
the final plat submitted for Case S-10346, i.e. CEA has submitted
two different requirements.)
2. Placing the following note on the plat:
a. "The property is located in Seismic Zone 5 as shown on the
Harding Lawson Report Seismic Map and has high ground
failure susceptibility in the event of a seismic occurrence.'
3. Clarifying the following items on the Detail and Plat Map:
a. Identify all the three easements (dotted) lines on the
southern property boundary. The dotted line 30 feet north of
the south property boundary is not identified. It aligns with
the north boundary of the Marston Drive right-of-way, which
is a dedicated street. Verify if this area along the south
property boundary is a Public Use Easement or dedicated
right-of-way. If dedicated, it needs to be stated on the plat.
b. Delineate the private right-of-way to indicate it is not a part
of the public right-of-way. Add vertical dividing line to plan
and detail views separating the "Private ROW' from Loussac
Street ROW and delete the extension of the Marston Drive

RE: GEOTECHNICAL REPORT FOR LOTS 11) & 11, BAST 31ST AVENUE,
ANCHORAGE, ALASKA
t
This letter report presents the results of our field explorations for the above referenced project.
_ The purpose of the field explorations were to determine the depth of the peaty soil known to occur in
the vicinity and to provide structural fill recommendations after the removal of the organic soil. To aid
in determining the depth of the organic material, four borings were advanced at the site. This report
presents the results of our field exploration .incl structural rill recommendations.
The site located on Lots 10 and 1 I at East 91 st Avenue just west of old Seward Highway, is
currently covered with grasses and weeds. The site is fairly level and there is wooden debris located
throughout the site. A previous field exploration was conducted by Shannon & Wilson on Lots 22
and 23, located directly south of Lots 10 & 11. The previous exploration results were presented in
the form of boring logs entitled 'T: 32nd Storage, Anchorage. Alaska" dated April, 1994. in the
previous six borings, the organic: layer varied in depth between 10.5 feet to 15.5 feet. The organic
material underlicd a fill material of brown gravelly sand to gravelly silt that varied in depth from 3.5
feet to 5.5 feet. No groundwater was encountered during the previous drilling. The previous boring
logs are presented in Appendix A.
Four borings, designated 13-1 through 13-4 were advanced at the site on the 17th of June, 1994
to define subsurface conditions. The locations of these borings are shown in Figure I. Detailed logs
of the borings are presented in Figures 2 through 5.
Drilling services for this project were provided by Discovery Drilling of Anchorage,
Alaska using a truck mounted CME 75 drill rig. The borings were advanced with a CME 8 -inch
outside diameter, 3-3/3 inch inside diameter hollow -stem auger. An experienced engineer from our
Firm was present continuously during drilling to locate the borings, ohscrve drill action, collect
samples, log subsurface conditions, and monitor any ground water encountered.

The borings for this project were completed to depths of 21.5 feet. As the borings were
advanced, samples were recovered at the at 2.5 foot intervals to 5 feet and at 5 foot intervals thereafter
in Borings B-1 and B-3. In Borings B-2 and B-4, samples were recovered at 5 feet and at 5 foot
intervals thereafter. Sampling was conducted using the Standard Penetration Test procedures. In this
test, samples were recovered by driving a 2 -inch O.D. split spoon sampler into the bottom of the
advancing hole with blows of a 140 -Ib. hammer free -Ladling 30 inches onto the drill rod. The number
of blows required to advance the sampler the final 12 inches of 18 inch penetration is termed the
Standard Penetration Resistance, which was recorded for each sample. 'These values are shown
graphically on the boring logs adjacent to the sample depth. The values give a measure of the relative
density (compactness) or consistency (stiffness) of cohesionless or cohesive soils, respectively. At
the end of drilling, all borings were back filled with native cuttings.
The locations of the horings were determined by our engineer using a cloth tape. The hole
locations, shown in Figure I, should therefore be considered approximate. Elevation data was not
available.
The subsurface conditions at the site are depicted in detail on the boring logs .in Figures 2
through 5. Three main soil types were encountered. it brown, slightly gravelly, sandy silt, a dark
brown peat, and it grey slightly gravelly, clayey silt. The brown, slightly gravelly, sandy silt was
encountered to a depth of betwen 3 feet to 5.5 feet. This material was medium dense to dense and is
considered fill material. Underlying this material was the loose, dark brown peat. The organic
material varied in depth between 6.5 to 10.5 feet. The shallow depth was encountered in Boring B-4
which was located in the northeast section of the site. A till deposit consisting of the grey, slightly
gravelly, clayey silt underlied the pro. This material was medium dense to very dense and contained
cobbles.
Groundwater was encountered during drilling at depths between 10 feet to 20 feet. The
shallower groundwater was encountered in Boring II -4, in the northeast section of the site. No
groundwater was encountered in Boring B -I which was located in the northwest section of the site.
This may be due to the till deposit encountered at deptli. This material typically container varing
amounts of clay an(I silt. 1 ligh clay anti silt content would reduce the amount of groundwater flowing
into the boring during drilling.

Moisture contents and grain size classifications were not conducted at the request of the client.
The brown, slightly gravelly, sandy silt was not tested to determine the percentage of fines, therefore
no recommendations on its use as a fill material can be made.
If the peat is removed, structural fill should be placed to level the site within a building
footprint. This fill should be granular and consist of a reasonably well graded mixture of sand and
gravel. Structural fill materials should be clean granular soils to provide drainage and frost protection.
These soils should also be non -frost susceptible (NPS), with less than about 6 percent (by weight,
based on minus 3/4 -inch portion) passing the H2(H) sieve.
All structural fills supporting building footings and floor slabs should be placed in lifts not to
exceed 10 to 12 inches loose thickness, and compacted to a density of at least 95 percent of the
maximum density as determined by the Modified Proctor compaction procedure (ASTM D-1557).
Prior to placing the structural fill for the proposed buildings, the site should be cleared of organics if
encountered in areas where development is planned. During rill placement, we also recommend that
large cobbles or boulders with dimensions in excess of R inches lie removed from any structural fills.
When backfilling within 19 inches of a building wall, materials should he placed in layers not
to exceed 6 inches loose thickness and densely compacted with hand operated equipment. Heavy
equipment should not be used as it could cause increased lateral earth pressures and possibly damage
adjacent walls.
The bottom of all footing excavations should be compacted to a density of at least 95 percent
of the maximum density as determined by the Modified Proctor compaction procedure (ASTM D-
1557).
The analyses, conclusions, and recommendations contained in this report are based on site
conditions as they existed at the time of the October. 1993, report and further assume that the
explorations are representative of the subsurface conditions throughout the site, i.e., the subsurface
conditions everywhere are not significantly different from those disclosed by our explorations and
observations. If, during construction, subsurface conditions different from those encountered in
these explorations are observed or appear to be present. we should be advised at once so that we can
review these conditions and reconsider our recommendations where necessary. If there is a
substantial lapse of time between the submission of this report and the start of work at the site, or if

conditions have changed duc to natural causes or construction operations at or adjacent to the site, it is
recommended that this report be reviewed to determine the applicability of the conclusions and
recommendations considering the changed conditions and time lapse.
Unanticipated soil conditions are commonly encountered and cannot fully be detennined by
merely taking soil samples or making test borineS. Such unexpected conditions frequently require
that additional expenditures be made to attain a properly constructed project. Therefore, some
contingency fund is rccommendcd to accommodate such potential extra costs.
Should you have any questions regarding information presented in this letter, please contact
its. We appreciate the opportunity to be of service to you.
