Introduction
Background
The 2014 University of Colorado Colorado Springs (UCCS) Recreational Trails
Micro-Master Plan provides a strategy for implementing a trail system that is
both a recreational amenity and an alternative experience for getting around
campus.
Purpose of the Recreational Trails Micro-Master Plan
The University of Colorado Colorado Springs (UCCS) has grown steadily since its
inception in 1965. The 2012 Campus Master Plan is grounded in the premise of
"respecting the responsible capacity of the land" and supported by three
design principles: 1) Respect natural features. 2) Reinforce vibrant campus
anchors. 3) Connect campus destinations. The Recreational Trails MicroMaster Plan embodies these concepts, as it is an addendum to the Campus
Master Plan.
As the designated growth campus within the CU System, the University has
already witnessed campus growth's impact on the current endemic trail
routes. The University also recognizes the unique opportunity presented by its
dramatic natural setting. In light of this context, the Micro-Master Plan aims to:
• Create a world-class trail system engaging the unique natural
landscape and contributing to UCCS's sense of place,
• Protect the natural environment by minimizing impacts to the local fauna,
flora, and soils while providing a robust trail system for recreation and
transportation,
• Accommodate campus development by creating a trail system that
connects and unifies campus destinations,
• Integrate the UCCS trail system with adjacent public trails, parks and
open spaces, as well as housing, retail and employment centers, and
• Recommend campus-wide initiatives to further the University goals of
sustainability, education, and holistic health and wellness.
UCCS Recreational Trail Construction B4 and G4 Project
The UCCS Recreational Trail Construction B4 and G4 is the first contracted trail
construction within the design standards established in the 2014 UCCS
Recreational Trails Micro-Master Plan. UCCS has high expectations for this
construction, as it will set the standard by which all future trail construction is
evaluated.

d. Obtain approval from Architect's or Owner's Representative before making
any changes.
e. Contractor shall not willfully proceed with construction as designed when it
is obvious that unknown obstructions and/or grade differences exist that
may not have been known during design. Such conditions shall be
immediately brought to the attention of the Owner’s Representative for
decision. The Contractor shall assume full responsibility for all necessary
revision due to failure to give such notification.
f.
Construction parking, materials staging, equipment storage, and port-o-let
location (required) will be determined with the Owners Representative
upon selection.
1. Mineral soil fill for flat trail construction is stockpiled on site. Refer to
Map of Work Area.
g. The contractor must secure all water required for the work either from
Colorado Springs Utilities or via contractor provided trucks.
h. Contactor shall provide a one year warranty on all workmanship. Needed
repairs shall be completed within 2 weeks, or as agreed upon with the

Construction Standards
i.
Protection of existing conditions
1. It is important that existing vegetation be protected. Watch your step as you are working as the
existing plants can be easily disturbed. When working, moving equipments, materials and personnel
or walking to or from the day's work site follow the trail corridor.
2. The contractor is responsible to replace, restore and maintain for 1 year any damage to
constructed or natural vegetation and built objects, irrigation, utilities or paving beyond the five (5)
foot trail corridor (12" beyond each side of the trail tread).
j.
Basic Trail
1. The tread width will be 36” and centered in the trail corridor unless
otherwise indicated in the construction notes. The trail corridor is 5 feet
wide and 8 feet high.
2. Remove only enough vegetation to remove all organic material, clearly
delineate the trail tread and clear the trail corridor. Existing rocks that
are stable within the trail tread are to remain.
3. Unless otherwise noted all trail construction is full cut bench trail.
k.
Reinforced Swale Crossings and Rock Crossing at Dry Stream Bed
1. Where called for in the plans, Siloam Stone rock pavers and boulders
shall be provided and installed by the contractor. Prior to purchase and
installation, the Contractor shall provide 3 samples of the Siloam Stone to
the Owner Representative for approval.
2. The trail tread for this project is to be maintained at 36” width. In areas
where Siloam Stone is used as paving or crossing, the width of the trail
tread shall be paved to 48” in width.
3. Rock Crossings will allow for trail users to cross over the surface and for
water to flow over or in between. In order to insure the safest crossing
possible, all pavers or boulders need to have a smooth top.
l.
Scrub Oak, shrubs and meadow duff disposal
Contractor shall transport all cleared and excavated materials to the
location on campus designated by the Owner’s Representative.
m. Project Sectioning and Methods
Project Staking, proved by Tapis Associates, the trail designer, is to
remain in place during trail construction. There are several different
trail indicators meaning the following:
100’ Station Markers: Wooden stakes in the ground uphill of trail centerline
Critical Edge of Trail: Pink Sprinkler Flags
Trail Centerline:
Varied colored survey whiskers may be located
on trail centerline at 50' intervals
General Notes
n. Disturbed Area Restoration
If areas beyond the trail corridor are disturbed during construction the
standard restoration procedure will be as follows:
1. Construct the rubble check dams, dips, and out-slope areas as
determined with the Owner's Representative.
2. The surface of all areas to be restored shall be scarified to 2” to 3”
depth.
3. Restore grade by “knocking down” edges along the disturbed area.
4. Seed trail closure area with the Upland Seed Mix specified in Appendix
G of the UCCS Recreational Trails Micro-Master Plan at a rate of 5
lbs/1000sf. See below.
5. Stabilize grades 3:1 and above with straw blankets installed per
manufacturers' specifications.
6. Cover with ½-4 inch depth native soil or “duff” (organic material from
adjoining trail construction).
7. Place deadfall on area if available.
