Re: Engineers statement of certification
All street finish centerline elevations are set a minimum of three feet above the highest established normal
groundwater elevation, per the attached on-site geotechnical investigation performed by Site Consulting on March
13, 2015.
If you require any additional information or supporting documentation, please let us know.

Re: Geotechnical Investigation
800 East Pine Street
Meridian, Idaho
Matt:
As per your request, on March 31, 2015 this engineer logged and sampled two test pits on the
subject property. The test pits were intended to provide subsurface information and design
recommendations for a proposed residential housing development. Test pits were excavated
approximately fifty feet south of the south end of Petersburg Way and Killdare Place. Our
project engineer logged the test pits and sampled the soils for additional laboratory testing.
The generated logs and all laboratory test results are included in the appendix. Based upon our
research the site is acceptable for the proposed construction.
The onsite soil profile includes a dark brown, moist, silt or sandy silt that extends to 2.0-2.5 feet
below the existing surface. This layer includes a 4 to 6 inch organic/ rootzone layer. Gravels
were contacted at this depth. The upper few feet of the gravels contains silt but the material
quickly grades to clean, free draining, sand and gravel. For design purposes, free draining sand
and gravel can be assumed present at 5.5 feet but this is to be confirmed at the time of
construction. Test Pits were both extended to approximately ten feet below the surface and
groundwater was not encountered. Sloughing sands and gravels prevented deeper
exploration.
It is noted that the water flow in the adjacent Five Mile Creek, that run parallel to the south
property line, was approximately 14 feet below the ground surface on the subject property. It
is anticipated that the onsite groundwater is slightly above this depth.

Based upon observed conditions the following recommendations are provided.
Shallow basins or infiltration trenches are recommended for stormwater disposal. The facilities
should extend to the free draining pitrun type sand and gravels encountered in the test pits.
Based on the use of ASTM C-33 sand as a filter media, a percolation rate of P=8 inches/hour for
free draining materials is recommended.
Pavement section for driveways and parking areas on the subject property have been designed
as is required for residential streets within ACHD's jurisdiction assuming a R -Value of R= 18 and
a Traffic Index of TI=6.0. This generates a pavement section of 2.5" ACP / 4.0" base / 10.0"
Subbase. The subbase can be reduced to 8.0" in parking lot areas only accessible to personal
cars and small trucks. It is noted that an R -Value sample has been submitted to a specialty
testing laboratory. When results are received the above pavement section will be modified as
indicated by actual test results.
Foundations can be designed based upon bearing pressures of up to 1500 psf. This assumes
that foundation will be founded atop the surface silt soil. Foundation support soils are to be
confirmed firm and stable prior to the placement of concrete or any required structural fill.
Foundations are to be embedded a minimum of 24 inches for frost protection. If crawlspaces
are planned, the construction joint between footings and foundation walls is to be sealed with
mopped or brushed on mastic.
Structural fill required to elevate the subgrade or backfill excavations may consist of onsite soils
free of organic material. All structural fills are to be compacted to 95% of the maximum dry
density as determined by ASTM D-698, "Standard Proctor". Compaction testing and inspection
of any fill greater than one foot thick is required.
We appreciate this opportunity to be of service and we look forward to working with you
during the design and construction of this project. Should you have any questions or require
additional information, please contact our office at your convenience.
