AMENDMENT TO LETTER DATED 5/21114
RE: Jeff Nalley Driveway Design Standard variance (10918 county Road 245)
CRE Job No. 1048
This shall be considered an amendment to the letter drafted by Colorado River Engineering
regarding the above referenced project, dated May 5I,2Ol4 signed by Jeffrey A Odor, P.E.
This is to serve as a response to Garfield County Building Department's request for "an
engineer's assessment of the switch back section of roadway and the potential need for additional
grading or drainage berms at the outside of the curve". The previous letter did not address the
specifics of the drainage related to the road. The drainage in this location is not of significant
concem. The storm water runoff from the vast majority of the area above this location is
intercepted by a ditch approximately 130 feet - 150 feet above the switch back. The area that
contributes to the ditch in question consists of a portion of the roadway and the small cut slope
adjacent to the roadway for a relatively short distance above the switch back. The roadside ditch
that is currently in place, though shallow, will carry the small amount of storm water runofffrom
this area with minimal or no impact to the driving lanes, largely due to the grade of the road and
ditch. The switch back area provides a flatter grade for a length to allow the energy of the runoff
to dissipate prior to leaving the roadside ditch and discharging into the adjacent natural drainage.
That being said, it is the owners responsibility to insure proper maintenance of the roadside
ditches and other related drainage structures. The owner may choose to expand the roadside ditch
to reduce the frequency of the maintenance.
It is also encouraged, though not required, by CRE that the owner use Best Management
Practices (BMP's) to minimize erosion and the transport of sediment. The erosion control BMP's
can include vegetation (preferred), surface roughening, artificial and temporary surface coverage
(erosion control blankets, etc.) or a combination thereof. The BMP's related to sediment
transportation would likely include a combination of a series of check dams with the ditch
ending in a sediment trap. Other BMP's are available and effective and may work better for the
owner. A qualified person familiar with local storm water regulations should be consulted,
should the owner decide to implement the use of BMP's.

Good morning Glenn
please see attached weed map and plan from Jeff Nalley. The plan is on the email from Jeff and essentially indicates his
recipe for treatment. He did map the areas where the thistle was, and I think we were able to ascertain that it was
Musk, not Canada thistle.
I am satisfied that Mr. Nalley provided the information re: noxious weeds that we requested. lf you are ok as well, l'll
send Jeff an email confirming that.
Thanks Glenn

Hi Jeff
You should have my email address now. If you oould sketch out the area on a map that would mark the
infestations and list the species teated. I have included flyers of both Canada and Musk thistle that may help
you identifu between the two species.
We also offer a cost-share progam that offers a partial reimbursement to lando\f,rners for weed control costs,
we'll have the program again in 2015 so keep that in mind should need sorne help with the purchase of weed
control materials.

Glenn,
I met with Jeff Nalley on Friday December \2,2074 at 10918 CR245, the location of the new proposed ADU. We
reviewed the access to the new proposed home and roughly laid out the access road and fire truck turnaround needed
for this new home. I am comfortable that the access being built will be to our fire department standards. Jeff and I
have an agreement that, as early as possible, I will inspect the all-weather driving surface on the access and the turn-
around. Thisinspectionwilltakeplaceassoonaspossiblenottohinderthe CofOofthisbuildingbeingissued.
Thanks again for allowing me to review and comment on this project. Please feel free to contact me with any questions

RE: Nalley ADU Update
Glenn: Thank you for the site plan and the photos, the site plan helps a lot. Due to the site plan not being to scale, I
will need to do a site visit during construction before C of O to ensure that we can access the ADU. I don't see this is a
big problem and will be happy to make the trip when the time comes. I think that Jeff has a pretty good idea on our
access needs and if any corrections are needed to be made, they should be small. Your condition of approval for a final
inspection from me will be adequate for out sign-off.
Please let me know if you need anything else from me for this project.
Thank you,

Subject: Nalley ADU UPdate
Hi orrin: Thanks very much for your review of this project. ln response to a couple of referral agencies including
yourself the Applicant provided a more clear site plan showing the location of the ADU and driveway. lt is to be located
just to the rear of and northwest of the existing house. l've attached a copy of the updated site plan along with a couple
photographs showing the area around the north end of the existing house where the ADU driveway will be configured.
Jeff Nalley also revised the plan to show a T-Type turnaround area as part of the ADU driveway'
ln light of your comments I am still looking at drafting a condition of approval calling for additional information on the
ADU driveway and the potential for a turnaround area requirement subject to your approval. Tamra Allen is reviewing
the draft staff report at this time.
Please call or email with any questions or updates' Thanks again.
Sincerely,

It is a good report. Condition #7 does require verification that it is meets the additional future demands from the ADU
l'll run it by our Building Department to see if we need anything further. How many total bedrooms will you be at

This sample tested ABSENT or <1 for presence of Coliform bacteria,
This sample tested NOT DETECTED for E. Coli.
Since coliform bacteria usually persist in water longer than most disease- causing organisms, the
absence of coliform bacteria leads to the assumption that the water in this sample is microbiologically
safe to drink.

Subject:subsoil study for Foundation Design, Proposed ADU Residence, 109r8
County Road 245 (Buford/lVest Elk Road), Garfield County, Colorado
Gentlemen
As requested, Hepworth-Pawlak Geotechnical, Inc. performed a subsoil study for design
of foundations at the subject site. The study was conducted in accordance with our
agreement for geotechnical engineering services to JeffNalley dated November 26,2014
The data obtained and our recommendations based on the proposed construction and
subsurface conditions encountered are presented in this report.
Proposed Construction: The proposed residence will be single story with slab-on-grade
floor located on the site approximately as shown on Figure 1. Cut depths are expected to
range between about 2 to 4 feet. Foundation loadings for this tlpe of construction are
assumed to be relatively light and typical of the proposed tlpe of construction.
Ifbuilding conditions or foundation loadings are significantly different from those
described above, we should be notified to re-evaluate the recommendations presented in
this report.
Site Conditions: The proposed building site had been rough graded relatively level and
was devoid of vegetation at the time of our study. The uphill, southwest part had been cut
and the downhill, northeast part had been filled each on the order of 3 to 5 feet in height.
Native vegetation consists of brush and pinon trees on the hillside west of the building
site' We understand that the existing 2-story residence is supported on shallow spread
footings and reportedly does not show signs of differential settlement distress.
Subsurface Conditions: The subsurface conditions at the site were evaluated by
excavating 2 exploratory pits at the approximate locations shown on Figure 1. The logs
of the pits are presented on Figure 2. Thesubsoils encountered, below about I to 2 feet of
mixed soil fill material, were variable and consist of sandy silty clay with gravel, cobbles
and scattered small boulders in Pit I and silty clayey sand and gravel with cobbles in pit

2. Results of swell-consolidation testing performed on clay samples from pit l, presented
on Figures 3 and 4, indicate low compressibility under existing moisture conditions and
light loading and a low to moderate collapse potential (settlement under constant load)
when wetted. The sample fromT feet depth may have been partly disturbed by the rock
content of the soil resulting in the higher compressibility potential than indicated by the
sample from 4 feet depth. Results of a gradation analysis performed on a sa:nple of
clayey sand and gravel (rninus 3 inch fraction) obtained from the site are presented on
Figure 4' No free water was observed in the pits at the time of excavation and the soils
were slightlymoist to moist.
f,'oundation Recommendations: Considering the subsoil conditions encountered in the
exploratory pits and the nature of the proposed construction, spread footings placed on the
undisturbed natural soil and designed for an allowable soil bearing pressure of 1,500 psf
can be used for support of theproposed residence with a risk of differential setflement
due to the variablebearing conditions. The clay soils tend to compress after wetting and
there could be post-construction, differential foundation settlemffit on the order of 1 to 2
inches. We should further evaluate the settlement potential and the need for compaction
of the bearing soils at the time of construction. Footings should be a minimgm width of
20 inches for continuous walls and 2 feet for columns. Loose disturbed soils and existing
fill encountered at the foundation bearing level within the excavation should be removed
and the footingbearing level extended down to the undisturbed natural soils. Exterior
footings should be provided with adequate cover above their bearing elevations for frost
protection' Placement of footings at least 36 inches below the exterior grade is tpically
used in this area. Continuous foundation walls should be reinforced top and bottom to
span local anomalies such as by assuming an unsupported length of at least 14 feet.
Foundation walls acting as retaining structures (if any) should be designed to resist a
lateral earth pressure based on an equivalent fluid unit weight of at least 55 pcf for the on-
site soil as backfill.
f,'loor Slabs: The natural on-site soils, exclusive of topsoil, are suitable to support lightly
loaded slab-on-grade construction. To reduce the effects of some differential movement,
floor slabs should be separated from all bearing walls and columns with expansion joints
which allow unrestrained vertical movement. Floor slab confiot joints should be used to
reduce damage due to shrinkage cracking. The requirements for joint spacing and slab
reinforcement should be established by the designer based on experience and the intended
slab use. A minimum 4 inch layer of well graded sand and gravel, such as road base,
should be placed beneath slabs for subgrade support. This material should consist of
minus 2inchaggregate with less than 50% passing the No. 4 sieve and less than}%o
passing the No. 200 sieve.

All fill materials for support of floor slabs should be compacted to at least 95% of
ma,rimum standard Proctor density at a moisfure conte,lrt near optimum. Required fill can
consist of the on-site soils devoid of vegetation, topsoil and oversized rock.
Underdrain System: An underdrain is not needed for the slab-on-grade construction
with floor level near to above adjacent finish exterior grade. If a betow grade area is
proposed, we should be contacted.
Surface Drainage: The following drainage precautions should be obseled dr:ring
consffuction and maintained at all times after the residence has been completed:l) Inundation ofthe foundation excavations and underslab areas should be
avoided during construction.
2) Exterior backfill should be adjusted to near optimum moisture and
compacted to at least 95Yo of themaximum standard Proctor density in
pavement and slab areas and to at least 90% of themaximum standard
Proctor density in landscape areas.3) The ground surface surrounding the exterior of the building should be
sloped to drain away from the foundation in all directions. we
recommend a minimum slope of l2 inches in the first 10 feet in unpaved
areas and a minimum slope of 3 inches in the first 10 feet in pavement and
walkway areas. A swale will be needed uphill to direct surface runoff
around the residence.
4) Roof downspouts and drains should discharge well beyond the limits of all
backfill.
5) Laodscaping which requires regular heavy irrigation should be located at
least 10 feet from the building. Consideration should be given to the use
of xeriscape to limit potential wetting of soils below the foundation caused
by irrigation.
Limitations: This study has been conducted in accordance with generally accepted
geotechnical engineering principles and practices in this area at this time. lVe make no
warranty either express or implied. The conclusions and recommendations submitted in
this report are based upon the data obtained from the exploratorypits excavated at the
locations indicated on Figure I and to the depths shown on Figure 2,theproposed type of
construction, and our experience in the area. Our services do not include determining the
presence, prevention or possibility of mold or other biological contaminants (MOBC)
developing in the future. If the client is concerned about MOBC, then a professional in
this special field ofpractice should be consulted. Our findings include interpolation and
extrapolation of the zubsurface conditions identified at the exploratory pits and variations
in the subsurface conditions may not become evident until excavation is performed. If
conditions encountered during construction appear different from those described in this
Job No.114527A
e&&ecn

report, we should be notified at once so re-evaluation of the recommendations may be
made.
This report has been prepared for the exclusive use by our client for design purposes. We
are not responsible for technical interpretations by others of our information. As the
project evolves, we should provide continued consultation and field services during
construction to review and monitor the implementation of our recommendations, and toverifr that the recommendations have been appropriately interpreted. Significant design
changes may require additional analysis or modifications to the recommendations
presented herein. We recommend on-site observation of excavations and foundation
bearing strata and testing of structural fill by a representative of the geotechnical
engineer.
If you have any questions or need further assistancg please let us know
