ROAD ASSESSMENT
ENCANA OIL & GAS (USA) INC.
K19NE STORAGE FACILITY (LAYDOWN YARD)
The following road assessment is to address Garfield County's Policy 04-01 waivers for roads
and demonstration of compliance. The purpose of the road assessment is to assess the subject
road for the Garfield County roadway standards listed within Table 7-107 of the Land Use
Development Code.
The Encana Oil & Gas (USA) Inc. (Encana) K19NE Storage Facility (Laydown Yard) Road
Assessment begins where the road turns off of County Road (CR) 333 in the SESE quarter of
Section 24, Township 6 South, Range 93 West of the 6th P.M. and terminates in Lot 3 of Section
19, Township 6 South, Range 92 West of the 6th P.M. at the Encana K19NE Laydown Yard. This
road is approximately 0.5 miles in length from CR 333 to the Laydown Yard. Included in the road
assessment is a road through private land shared for access to Encana Pad K19CNE, which is
approximately 0.2 miles in length. The remaining 0.3 miles is on Encana property and is used
solely to access the K19NE Laydown Yard. Encana performs the maintenance on the entire road.
Field observations and data gathering were conducted on November 18, 2014. The observations
are summarized as an attachment to this assessment.
Statement of Adequacy
This road is typical of roads providing access to natural gas production facilities in Garfield County.
The roadway is adequate for the intended use.
Geometry of Road
The following table compares this road to the Garfield County roadway standards found in Table
7-107 of the Land Use and Development Code for Primitive Road/Driveway.

1 As determined adequate in an engineering review. Primitive road shall be dedicated ROW,
driveway can be dedicated as either an easement or ROW.
2 If determined necessary for adequate drainage.
The road is across private land, and there is a 45 ft. wide Access Easement (Garfield County
Reception Number 650315).
The road width varies between 13.2 and 23 feet. This meets the minimum requirement.
Where ditches are present, they range in width from 2.0 to 7.5 feet. The ditches are fairly shallow.
The cross slope varies between 0.6% and 7.3%. In some places, the road slopes toward the side
of the road without a ditch, including some areas where the road is crowned.
There is no posted speed limit on the road.
The horizontal radii range from 50 feet to 310 feet. All the turns meet the minimum 40 foot
standard radius.
The grade for the road varies between 0.4% and 14.4%. The areas where the grade is greater
than 12% occur in short sections. The road is surfaced with gravel.
The road geometry changes occasionally with maintenance activities. Cross slopes change
during maintenance operations. The road was built to follow the general topography of the area
with minimal change to the natural grade.
Safety/Structural Issues
A significant drop off adjacent to the road was observed on the right side of the road approximately
from stations 13+50 to 19+00 and on the left side of the road approximately from stations 16+70
to 24+00. Mitigation methods should be evaluated during maintenance operations.
Overall the roadway did not exhibit obvious safety or structural issues during the date of the field
observation, November 18, 2014.
Maintenance
Encana does all of the maintenance on the road. The road is inspected on a regular basis for
maintenance issues. Maintenance includes grading as needed to remove washboard and repair
potholes. The road surface is graveled as needed to maintain the road base with attention to dust
control. Speeds are low to promote safety and reduce road damage.
Travel Demand
Average Daily Traffic (ADT) for the proposed project is expected to be less than 20 vehicles per
day (VPD) as shown in the Basic Traffic Study prepared by Olsson Associates, dated January
2015 (study). As a result, this roadway is being assessed according to the standards for a
Primitive Road/Driveway.
Access Road Assessment Page 2
K19NE Storage Yard January 2015

As mentioned within the study, traffic associated with the use as a storage facility at the site is
primarily pickup trucks, 4 trips per day. Additionally, a heavy truck will access the site one time
every two months. Typical daily volumes will be approximately 4 trips per day with the potential
for 6 trips.
Other Evidence of Compliance
Section 7-107.A Access to Public Right -of -Way
The private road to the site has direct access to CR 333. A copy of the driveway permit is included
at the end of this section.
Section 7-107.8 Safe Access
Access to the site is consistent with other similar uses.
Section 7-107.0 Adequate Capacity
Traffic congestion is not anticipated as a result of the proposed use. The roadway capacity is
expected to be sufficient for the intended use.
Section 7-107.D Road Dedications
The road has a 45 foot wide Access Easement (Garfield County Reception Number 650315).
Section 7-107.E Impacts Mitigated
Based on the expected trip generation rates discussed in the Basic Traffic Study, the increase in
average daily traffic is not expected to increase on County Roads such that a modification of the
existing access permit would be required. The total traffic volumes are expected to remain very
low and are anticipated to be accommodated by the existing roadway.
Conclusions
The road assessment identified areas that deviate from the Design Standards in Table 7-107 for
ditch width, cross slope, and maximum grade.
Where there are discernible ditches along the road, the ditch width varies. Locations 1, 2, 4-7
have ditch widths less than 3 feet. Some of the road has ditches on one side only or no ditches
at all. In some areas, the cross slope inclines toward the side of the road where there is no ditch.
As a result, areas will have ponding water that could lead to the need for additional maintenance
over time. There are no defined shoulders though most areas of the roadway are wide enough to
consider shoulders as an extension of the lane width. There is a dedicated turn -out at
station13+25 with a width of 24.5 feet.
The cross slope varies from 0.6% to 7.3% along the road. The road geometry changes
occasionally with maintenance activities. While ponding may occur in areas of shallow cross
slope, the road is inspected on a regular basis for maintenance issues, which are addressed in a
timely manner.
The grade for the road varies between 0.4% and 14.4%. The areas where the grade is greater
than 12% occur in short sections.

to natural gas production facilities in Garfield County.
