Permitted Construction / Details:
This Brock Consulting, LLC engineer design dated May 30, 2014 is for a 2 bedroom residence. Install per
design a 1000 gallon, two compartment concrete septic tank with a clean out between the dwelling and
the tank. Use schedule 40 PVC or C900 pipe. The absorption field is to consist of 20 Quick 4 Infiltrator
units in one trench to provide 400 sq ft of absorption area credit. Trench should follow the natural surface
contours and be level. Rake trench bottom and sidewalls to eliminate smearing. Provide inspection
portals at ends of the trench.
Maintain all required setbacks. Do not install in wet or frozen soil conditions. Call the design engineer
for a final inspection before burying any of the system components. In order to receive final approval, the
engineer must provide the final certification letter, photos of the installation, and as-built drawings of the
system.

REQUEST TO EXTEND PERMIT
Dear Environmental Health:
The purpose of this letter is to request an extension of the OWTS (private residential
wastewater system) permit to November 15, 2014. Being well aware that colder
temperatures are forthcoming and thus the potential for frost, additional time is
needed to complete other utilities that are being held back by others. Regardless, no
frost or other inferior soils will be used in the backfill.
Thanks for your understanding.

Subject: Observation of Backhoe. fits, Existing Detached Garage. Lot 4, Eagle
River Preserve, 575 Willowstone Drive. Gypsum. Colorado
Dear .Ton:
i
As requested, a representative of Hepworth-Pawlak Geoteclinical; Inc. observed the
backhoe pit excavations at the subject site on April 4. 20I4 to evaluate the soils exposed
for foundation support. The findings of our observations and recommendations for the
foundation design are presented in this report. The services were performed in
accordance with our' agreement for professional engineering services to you, dated
March 6, 2014. We previously observed the foundation excavation for the existing
residence on the lot and submitted our findings in a report dated March 31, 2004 under -
Our Job No. 104 �37.
The existing barn lis several years old and being remodeled as an auxiliary dwelling unit
(ADU). The rembdelin; will include a second floor living area in the current 10:ft. The
ground floor will be slab -on -grade. The structure is reportedly founded on 18 inch
diameter wooden posts bearing about 5 feet deep around the perimeter of the building.
No signs of excessive settlement and distress to the structure were observed by us or
reported by the owner. The existing residence, which was built in 2004, is Founded on
shallow spread fo¢tings with no signs of excessive settlement and distress reported.
The site is underlain by Pennsylvania Age Eagle Valley Evaporate bedrock. The
evaporite contairrslgypsum deposits. Dissolution of the gypsurn under certain conditions
can Cause sinlcltolgs to develop and can produce areas of localized subsidence. During
previous work in & area.. sinkholes were observed scattered in the Gypsum and other
areas of the Eagle valley. Sinkholes were not observed in the immediate area of the
subject lot. Basedl on our present knowledge of the site, it cannot be said for certain
that sinkholes will'not develop. In our opinion. (lie risk ofground subsidence at Lot 4
is low and similar Ito other lots in the area but the owner should be aware of the
potential For sinklipie development.

At the time of our site, two backhoe pits had been exca ted near the barn. Pit 1 was
about 3 feet from the southeast building corner and Pat was about 3 feet from the
northwest building corner. The soils exposed in the pits, below a few inches of topsoil,
consisted of loose, very silty sand to very sandy silt with scattered gravel and small
cobbles that extend down to the pit depths of 614 and 7 feet, respectively. The sample
from the bottom of Pit 2 (at 61/2 feet) was medium dense and rockier. The soils
contained some Igypsum. Results of swell -consolidation testing performed on samples
taken from the pits, shown on Figures 1 and 2, indicate the soils are moderately to
highly compressible under conditions of loading and wetting with a moderate hydro -
compression potential. The samples may have been partly disturbed. The laboratory
test results are summarized in Table 1. No free water was encountered in the pits and
the soils were slightly moist to moist.
Considering the conditions exposed in the pits, the performance of the existing building
and residence, and the nature of the proposed construction, spread footings placed on
the undisturbed natural soil designed for an allowable bearing pressure of 1,500 psf can
be used for support of the building, with a risk of settlement. The risk of settlement is
primarily if the bearing soils become wetted and precautions should be taken to prevent
wetting.
Footings should be a minimum width of 18 inches. Loose and disturbed soils in footing
areas should be removed and the bearing level extended down to the undisturbed natural
soils, and the subgrade compacted. Exterior footings should be provided with adequate
soil cover above their bearing elevations for frost protection or protected by ground
insulation. Continuous foundation walls should be reinforced top and bottom to span
local anomalies such as by assuming an unsupported length of at least 12 feet. A
perimeter foundation drain around the structure is not needed due to the slab -at -grade
construction. Structural fill placed within floor slab areas can consist of the on -site soils
compacted to at least 95 % of standard Proctor density (SPD) at a moisture content near
optimum. Backfill placed around the structure should be compacted to at least 90 %
SPD and the surface graded to prevent ponding within at least 10 feet of the building.
Landscape that requires regular heavy irrigation, such as sod, and sprinkler heads
should not be located within 10 feet of the foundation.
The recon naendations submitted in this letter are based on our observation of the soils
exposed within the pit excavations. This study is based on the assumption that soils
beneath the bottoms of the pits have equal or better support than those exposed. The
risk of foundation movement may be greater than indicated in this report because of
possible variations in the subsurface conditions. In order to reveal the nature of the
subsurface conditions with depth, drilling would be required. It is possible the data
obtained by subsurface exploration could change the recommendations contained in this
letter. Our services do not include determining the presence, prevention or possibility
