Re: Excavation/Street Cut Permit # 160046 - Lot 2 Coke Ovens
Subdivision Exemption - Property Address: TBD Airport Road,
Glenwood Springs, CO
Dear Jessica:
This letter is in response to your email dated December 27, 2016 requesting
additional information to finalize the Excavation/ Street Cut Permit number
160046 issued December 9, 2016.
As the Engineer and Surveyor working on the development of Lot 2 Coke
Ovens Subdivision Exemption, we respectfully request an ingress and egress
easement across two points in the Right of Way of County Road 163 (Airport
Road).
The property owner proposes to construct two twelve foot wide gravel
driveways to access a proposed two story office and shop building. The
lengths of the proposed upper and lower driveways across the Right of Way
would be forty-eight and sixty feet in length respectively. The distance
between the proposed driveways, as measured from each centerline along
the existing west edge of the County Road, is 568 feet.
The southern access is constructed within an access easement that is
depicted on the recorded plat of the Coke Ovens Subdivision Exemption Plat
for a common driveway serving both Lots 2 and 3 of the Coke Ovens
Subdivision Exemption.
With respect to anticipated future traffic volumes, we offer the following
information. According to the owner of Lot 2, he expects to have 6 full or
part-time employees working from the building. On that basis, according to
the 8th Edition of the ITE Trip Generation Manual, 6 full-time employees
would result in a calculation of 22 vpd.
Using another approach, the proposed building is a two-story building with
the upper level being the office and the lower level being a maintenance
shop. Each level contains approximately 3,245 sq.ft. Therefore, on the basis
of floor area, according to the ITE (Single Tenant Office Building - 715), the
office area would result in a calculation of 38 vpd. And, the lower level

maintenance shop area (General Light Industrial - 110) would result in a calculation of 23
vpd, for a total of 61 vpd for the site. We believe that this is probably an over-estimate of
the actual vpd for this site.
Regarding traffic counts for the adjacent property to the south (Lot 3), it is our
understanding that the adjacent property is currently vacant. Therefore, under current
conditions the ADT should be essentially zero. Under future build -out conditions, this
property is zoned Commercial/General in Garfield County, the allowed uses of which are
extremely varied based on the County's zone district standards, and therefore it would be
difficult to estimate the future traffic volumes for that Lot. However, we would expect that
whatever future use is developed on Lot 3 it would require another access permit with the
City and at a minimum it would require that the common portion of the driveway be
widened from the currently proposed one -lane configuration to a two-lane configuration.
Please contact us if you have any questions or need additional information.
Sincerely,
Gamba & Associates, Inc.
