Entrance 1
Centerline is on Trac$16 and 17 joint tract line. lt is 50 feet deep
The driveway is 50' deep with a drainage ditch running easterly along the south edge of
the driveway into a 15" culvert pipe directing runoff to County Road 335 drainage ditch.
I propose a 30' x 10' x 6" concrete pan abutted to County Road 335, as
recommended by Garfield County Road and Bridge. The concrete will be built on 4" of
class 6 road base. The remainder of the driving surface will be 6" of class 6 road base
and all road base will be compacted to g5% standard proctor.

West Divide Ranch LLC Ranch Road Project and BPM's
1. Project Description
Total Area: 102,300 S.F.
2. Clearing and Grubbing
Total Area: 1 02,300 S.F.
3. Shape and Grading
TotalArea 102,300 S.F
The project includes improving an existing ranch road to conform to Garfield County
roadway standards for primitive and semi-primitive specifications.
The existing roadway is adjacent to County Road 335 and only intersects CR 335 and
only intersects CR 335 at 2 existing entrance points. One point is within the city limits
of New Castle. The second is in Garfield County. All other roadway is on private
propefty and not County right-of-way.
The existing roadway is within the 75' access easement recorded on the plat labeled
Grand Hogback Ranches, Reception # 967927. The roadway will remain private
property.
A 3rd existing entrance point is within the City Limits of New Castle. An improvement
permit has been requested from New Castle. At this point the existing driveway has not
been improved by grading, only additional gravel has been placed on the surface.
A driveway permit has been acquired from Garfield County Road and Bridge, Permit #
GRB22-D-6 dated 3/28/2022 (copy included)to improve the entrance on Tract 5.
A Rainfall Erosivity Waiver for exclusion from CDPS stormwater permitting for small
construction projects (less than 5 acres) application (copy included) has been
submitted.
The existing grade and finished grade of the roadway remains the same, therefore a
topo site plan should not be required.
The soils include varying depths of 0" to 12" of topsoil. Sub-grade soils are of heavy
clays and sandstone mix. These soils and the climate are very stable factors regarding
erosion and revegetation.
Removal of all vegetation and organic material from the roadway surface. Clearing
material to be place above the roadway and was incorporated into south slope and
preformed by bulldozer and Motor Grader.
A Bulldozer and Motor Grader completed the majority of the work. The roadway is
an existing roadway that needed to be re-established, therefore limited earthwork or
disturbance was necessary. Once the road was re-established, final shaping and
compaction will prepare the roadway surface for road base placement. Ditches and
culvert pipes was placed to control precipitation runoff. Cut and fill slopes are
prepared for revegetation. Gravel placement will be preformed and is imperative to
controlsoil erosion.
