BETWEEN EAGLE COUNTY, COLORADO
AND THE TOWN OF EAGLE
FOR USE, OPERATION AND MAINTENANCE OF THE EAGLE RIVER PARK AT
THE EAGLE COUNTY FAIRGROUNDS PROPERTY
THIS FIRST AMENDMENT to the Agreement for Use, Operation and Maintenance of the
Eagle River Park at the Eagle County Fairgrounds Property dated ______________ (“First
Amendment”) is between Eagle County, Colorado, a body corporate and politic, by and through
its Board of County Commissioners (“County”) and the Town of Eagle, by and through its Town
Council (“Town”). Together, the Town and the County are referred to as the “Parties.”
WHEREAS, the Parties initially entered into an agreement dated December 6, 2017, (Eagle
County C17-402) amended on March 27, 2018, (Eagle County C18-114) to allow the
construction of the Eagle River Park on certain portions of the Premises, subject to the terms and
conditions contained therein (collectively the “Construction Use Agreement”); and
WHEREAS, the Parties subsequently entered into an agreement dated May 21, 2019 (Eagle
County C19-173), for the use, operation and maintenance of the Eagle River Park at the Eagle
County Fairgrounds during and after completion of construction (the “Use Agreement”); and
WHEREAS, the Town’s construction activities at the Eagle River Park authorized by the
Construction Use Agreement are complete; and
WHEREAS, prior to the Town’s construction activities at the Eagle River Park, the County
asserts that the Eagle County Diversion Structure for the Neilson Pumpback Irrigation Headgate
(“Headgate”) received water when river flows were at or above 200 cubic feet per second (c.f.s.),
as measured at the United States Geological Survey (USGS) Stream Site 0907000 Eagle River
Below Gypsum, CO (“Gypsum Gage”) (“Proper and Historic Headgate Function”); and
WHEREAS, the Town’s construction drawings titled “Eagle River Park” by S2O Design and
Engineering (“S2O”), dated September 26, 2017 (the “Plans”) included a re-design of the Eagle
County Diversion Structure for the Headgate, which included a dry-stack crossvane structure
with an attached grade control structure (the “Crossvane Diversion Structure”); and
WHEREAS, the Plans called for the Crossvane Diversion Structure to maintain water levels
above the Headgate intake pipe for flows above 90 c.f.s., without impacting the 100-year flood
plain; and
WHEREAS, after construction in 2019, the County reported to the Town that the Headgate did
not receive water anytime river flows dropped below 270 c.f.s., as measured at the Gypsum Gage
and therefore did not allow for Proper and Historic Headgate Function; and

WHEREAS, Eagle County commissioned and paid $55,819.70 for construction work to restore
the Crossvane Diversion Structure to the standard set forth in Plans in accordance with S2O’s
Repair Plan – including certain additional modifications recommended the design engineer to
ensure adequate protection of the Crossvane Diversion Structure and adequate mitigation of
hydraulic drops in the interest of reasonable boater safety, described in Exhibit B-1 and Exhibit
B-2, attached hereto and incorporated herein by this reference (the “Repair Plan”);
WHEREAS, the Town intends to reimburse Eagle County the amount paid for the construction
work to restore the Crossvane Diversion structure as described above;
WHEREAS, the Crossvane Diversion Structure is located immediately upstream of the Eagle
River Park and therefore also serves as the Eagle River entry to the whitewater park, which
required the design in the Plans and Repair Plans to consider boater safety; and
WHEREAS, in exchange for permission to construct and operate the Eagle River Park on the
Premises, the Town commits to defend Eagle County from any claims or liability related to the
public recreational use of the Eagle River Park, including the entire Crossvane Diversion
Structure; and
WHEREAS, the Town further commits to maintain the Crossvane Diversion Structure to
maintain Proper and Historic Function of the Headgate, and commits that any maintenance or
repair work and/or design will also take into consideration public safety; and
WHEREAS, the Parties wish to amend the Use Agreement to set forth the Parties’ expectations
regarding repair and ongoing maintenance of the Crossvane Diversion Structure; and
WHEREAS, the County informed the Town that certain issues arising from construction and
first-season use activities at the Premises impacted the County’s primary uses of its property and
created additional costs for the County, and therefore, further planning and cooperation over
time will be necessary before the County is prepared to subdivide and convey portion of the
Premises to the Town.
NOW THEREFORE, in consideration of the terms and covenants stated herein, the sufficiency
of which is hereby acknowledged, the Parties agree the Use Agreement shall be amended as
follows:
1. Exhibit A to the Use Agreement is hereby replaced with Exhibit A-2, which is attached
hereto and incorporated herein by this reference. For the avoidance of any doubt, the term
“Premises” in this Agreement shall be construed to include the entire Crossvane Diversion
Structure, notwithstanding that some portion of the structure may encroach outside of the Eagle
County parcel boundary lines.

Proposed Approach
S2O recommends that one of our representatives be on site during repair of the diversion structure and
grade control as described below. This will enable S2O to provide technical guidance and quality control,
in addition to providing an opportunity to ensure that County and Town maintenance personnel have a
clear understanding of the design and preferred construction methods.
To complete maintenance activities described above, S2O recommends the following process:
1. Salvage displaced boulders below the diversion structure provided they are not part of the
roughened riffle design immediately above feature #1. Import additional boulders if necessary.
2. Reconstruct the damaged section of cross-vane to the elevations provided by the original
design, utilizing the largest boulders manageable with available equipment (5-6ft minimum
diameter recommended).
3. Repair scour pad per design. S2O suggests upsizing material to 24” riprap to reduce potential
maintenance to the extent possible.
4. Re-install material upstream of the Cross-Vane which washed through the damaged section.
Again, it is suggested that material be upsized to 24” riprap with smaller cobble and alluvial
material to fill void space, reducing potential maintenance to the extent possible.
5. Re-construct damaged portions of the grade control immediately downstream of the diversion
cross-vane using the largest boulders available and manageable with available equipment (5-6ft
minimum diameter recommended)
6. Repair any damage to the maintenance ramp during demobilization of equipment.
The attached sketch identifies the repair areas described above and preferred repair. Elevations to
restore the diversion structure, grade control and armoring may be found in the permitted construction
drawing set.

Riffle Reconstruction
S2O (Scott Shipley, Riley Adams) participated in an onsite meeting with Hobbs (Stewart Hobbs), Eagle
County (Kevin Sharkey) and NV5 (John Usery) on 3/13/2020 to determine the best approach to
reestablish the riffle between the diversion structure and ERP Feature 1. The foremost concern was that,
due to the amount of bed material removed, a large elevation drop has formed below the grade control
which likely will create a dangerous hydraulic condition at high flows. Priorities discussed during the
meeting included reestablishing design grade through the riffle to eliminate the hazardous condition
and attempt to provide more resiliency to future flood events while importing the least amount of
material possible to keep additional costs low.
It was determined that the best approach was to add an additional partial grade control downstream of
the diversion structure to step grade down gradually, and fill between the two grade controls with 24”
boulder armoring material obtained from Eagle County’s pit. Additionally, 24” boulder armoring material
would be packed in on the downstream side of the added grade control to prevent scour and rebuild the
rock riffle to tie into existing grade upstream of ERP Feature 1. This solution matches the existing design
grades and substrate material while providing more resiliency and reinforcing the diversion structure. A
sketch of the proposed repair is provided below for clarification.

Figure 4: Profile Sketch of Post‐Flood Conditions and Proposed Reconstruction at Thalweg
The material received from the Eagle County pit was somewhat smaller than 24”, however it is very
angular, and Hobbs was diligent about tracking the material in well with the excavator. The angular
nature will help to lock the material together better than rounded material and should keep it in place
during high water events.

Hobbs completed installation of the additional partial grade control and reconstruction of the riffle
between the diversion structure and ERP Feature 1 on 3/17/2020. S2O checked elevations (using same
benchmark as previously described) of the additional grade control to provide a more gradual loss of
elevation leading into the riffle. In some cases visibility was non‐existent in areas covered with water, so
S2O relied on information relayed by Hobbs on location and placement of toe boulders for the cross‐
vane repair, grade control installation and placement of 24” armoring material. Additionally, several
boulders previously placed in the riffle were adjusted based on feedback from members of the local
rafting community. The completed riffle reconstruction successfully restores design elevations,
eliminates a serious safety concern and provides greater resilience to high water events.
