PITKIN COUNTY CONTRACT FOR PROVISION OF SERVICES
THIS CONTRACT, made December 13, 2021 by and between the Board of County
Commissioners of Pitkin County, Colorado, 530 E. Main St., Suite #302, Aspen, CO 81611,
(hereinafter called the "County") and Lotic Hydrological, LLC, PO Box 1524, Carbondale, CO
81623 (hereinafter called the"Contractor")to perform the following work: Crystal River Resource
Enhancements ("Project").
I. Term of Contract: The term of this Contract is from December 13, 2021 to December
31, 2022. At the expiration of the initial term, the contract may be extended for an
additional term of one (1) year by the express written consent of both parties.
II. Contractor's Obligations. Contractor will complete a total of six tasks in partnership
with Brad Johnson, Ph.D., from Johnson Environmental Consulting (JEC). The scope
of each task and the expected results and deliverables are discussed below:
Task 1: Literature review: Lotic and JEC will review a report produced by Peak Ecological in 2021
that discusses the characteristics of riparian vegetation in the TCOS. Special attention will be given
to any discussion of degraded conditions or opportunities for ecological lift.
Task 2: Site Visits: Two site visits will be conducted to verify local conditions discussed in the
Peak Ecological report and contemplate site-specific actions that might be taken to enhance the
ecological and structural characteristics of the stream corridor. A rapid survey of the channel and
selected floodplain surfaces will be performed using a laser level and/or RTK GPS survey
equipment.
Task 3: Topographical Data Analysis: Light Detection and Ranging (lidar) imagery for the TCOS
will be retrieved from the Pitkin County GIS Department and used to create a Digital Elevation
Model (DEM) of the stream corridor. The DEM will subsequently be processed in a GIS to create
a Relative Elevation Model (REM) for floodplain surfaces and terraces. The REM will help
identify dissected floodplain pockets and other surfaces amenable to some type of riparian
restoration or hydrological reconnection project. The REM will also be used in concert with aerial
imagery and notes collected on site visits to map the extent of the active riparian area and the
potential riparian area throughout the stream corridor.
Task 4: 2D Hydraulic Modeling: The DEM developed in Task 3 will be used to create a 2D
hydraulic model of Thompson Creek through the focal area.The model will be created using either
the HEC-RAS or FastMECH software. The U.S. Geological Survey(USGS) StreamStats program
1
Contract#243.21 Revision:2018-06-13 btf
Budget Line Item#11836360.531000
will be used to characterize peak streamflows for lower Thompson Creek with 2-, 5-, 10- and 25-
year return intervals. These peak streamflows will be simulated in the model and used to map
inundation extents associated with each flood size. These flood extents will be used to refine the
mapping of active and potential riparian areas produced in Task 3.
Opportunity may exist to work with staff from the USFS to complete this task, as some modeling
data sets for the site may already exist.The possibility of this type of collaboration will be explored
as needed.
Task 5: Project Opportunity Identification: The information generated by each of the Tasks
described above will be used to characterize a suite of projects and interventions that Pitkin County
may undertake at TCOS to improve the ecological and fluvial geomorphological characteristics
and functions of the Thompson Creek stream corridor. Opportunities for consideration may
include, but will not be limited to, the following:
• Reconnecting streamflows to dissected floodplain pockets;
• Riparian vegetation plantings on regularly inundated surfaces;
• Installation of beaver dam analogs;
• Placement of very large woody debris in the stream channel;
• Excavation of floodplain surfaces to expand active riparian area and decrease hydraulic
energy during flood conditions; and
• Excavation of secondary channels to move water further into the floodplain during high
flow events.
All opportunities identified will be accompanied by a discussion of any relevant requirements and
constraints. These may include,but will not be limited to, the following:
• Property ownership limitations;
• Heavily altered late-summer hydrological conditions;
• Permitting requirements;
• Order of magnitude budget estimation;
• Ongoing maintenance requirements;
• Water rights implications; and
• FEMA floodplain mapping considerations.
The 2D hydraulic model produced in Task 4 may be used to evaluate potential outcomes associated
with any given opportunity.
Staff from the U.S. Forest Service (USFS) will be engaged in the discussion of project
opportunities since USFS previously indicated some desire to use any work completed at TCOS
as a demonstration project for increasing climate resiliency in similar waterways across the region.
Task 6: Final Reporting and Presentations: This Task includes development of all final reporting
materials and two meetings/presentations to stakeholders. Both meetings will include Pitkin
County OST staff and members of the Crystal River Working Group. The first meeting will be
scheduled to occur after completion of Task 5 and prior to finalization of the conceptual plan.
2
Contract#243.21 Revision:2018-06-13 btf
Budget Line Item#11836360.531000
Participants will be invited to review a drafter version of the conceptual plan and provide feedback.
The second meeting will occur following completion of the final deliverable This meeting will be
used to clarifies how recommendations/concerns elevated at the first meeting were incorporated
into the final deliverable. A brief presentation of the content included in the final deliverable will
also be made.
Expected Results and Deliverables: This effort will produce a conceptual bank
stabilization/riparian enhancement plan. The plan will discuss existing ecological, hydrological,
and fluvial geomorphological conditions at the site, opportunities for enhancing ecological
conditions and functions, and the potential budget, legal, permitting and other constraints
associated with those opportunities. The plan will include maps, renderings, and graphics and will
be delivered to Pitkin County in digital form as a single document with appendices.

1.0 Summary
The Pitkin County Open Space and Trails (OST) department requests an assessment of existing
conditions and identification of opportunities for enhancing the functional characteristics of the
stream channel and adjacent riparian areas on the portion of Thompson Creek that flows through
the Thompson Creek Open Space (TCOS) parcel,south of Carbondale.The project focal area
includes the southern portion (approximately eight acres) of Thompson Creek Open Space along
Thompson Creek between Highway 133 and the creek's confluence with the Crystal River,and the
west bank of the Crystal River below the confluence.
This effort will consider the topographical structure of the focal area,the interplay between stream
hydrology and channel hydraulics,and the current and potential extent of active riparian areas as
the primary means for identifying project opportunities.This work will review and extend findings
from a riparian assessment conducted by Peak Ecological on the TCOS in 2021.The primary
deliverable produced by the effort will be a conceptual plan that identifies a range of project
opportunities at different locations along the stream corridor. The potential ecological lift
associated with each opportunity will be discussed.The plan will also outline some of the
complicating factors that may arise due to permitting,land ownership,water rights,and other
constraints.
1.0 Basis of Need
The Crystal River Working Group,an ad hoc entity focused on improving flood resilience,floodplain
connectivity,and riparian habitat(diversity and connectivity) in the Crystal River valley,is
interested in understanding opportunities for enhancing riparian resilience on the TCOS.OST's
goals for managing the southern portion of the TCOS property,generally,align with this group.The
work proposed here will deliver a conceptual planning document useful to OST staff and the Crystal
River Working Group as they endeavor to strategically fund and implement projects at this and
other locations throughout the watershed in the coming years.
2.0 Approach
This effort will require completion of six tasks.Each task is discussed below.Lotic will partner with
Brad Johnson,Ph.D.from Johnson Environmental Consulting(JEC)to complete this effort.
Task 1: Literature review
Lotic and JEC will review a report produced by Peak Ecological in 2021 that discusses the
characteristics of riparian vegetation in the TCOS.Special attention will be given to any discussion
of degraded conditions or opportunities for ecological lift.
Task 2: Site Visits
Two site visits will be conducted to verify local conditions discussed in the Peak Ecological report
and contemplate site-specific actions that might be taken to enhance the ecological and structural
characteristics of the stream corridor.A rapid survey of the channel and selected floodplain
surfaces will be performed using a laser level and/or RTK GPS survey equipment.

Light Detection and Ranging(lidar) imagery for the TCOS will be retrieved from the Pitkin County
GIS Department and used to create a Digital Elevation Model (DEM) of the stream corridor.The
DEM will subsequently be processed in a GIS to create a Relative Elevation Model (REM) for
floodplain surfaces and terraces.The REM will help identify dissected floodplain pockets and other
surfaces amenable to some type of riparian restoration or hydrological reconnection project.The
REM will also be used in concert with aerial imagery and notes collected on site visits to map the
extent of the active riparian area and the potential riparian area throughout the stream corridor.
Task 4: 2D Hydraulic Modeling
The DEM developed in Task 3 will be used to create a 2D hydraulic model of Thompson Creek
through the focal area.The model will be created using either the HEC-RAS or FastMECH software.
The U.S.Geological Survey(USGS) StreamStats program will be used to characterize peak
streamflows for lower Thompson Creek with 2-, 5-, 10-and 25-year return intervals.These peak
streamflows will be simulated in the model and used to map inundation extents associated with
each flood size.These flood extents will be used to refine the mapping of active and potential
riparian areas produced in Task 3.
Opportunity may exist to work with staff from the USFS to complete this task,as some modeling
data sets for the site may already exist.The possibility of this type of collaboration will be explored
as needed.
Task 5: Project Opportunity Identification
The information generated by each of the Tasks described above will be used to characterize a suite
of projects and interventions that Pitkin County may undertake at TCOS to improve the ecological
and fluvial geomorphological characteristics and functions of the Thompson Creek stream corridor.
Opportunities for consideration may include,but will not be limited to,the following:
• Reconnecting streamflows to dissected floodplain pockets;
• Riparian vegetation plantings on regularly inundated surfaces;
• Installation of beaver dam analogs;
• Placement of very large woody debris in the stream channel;
• Excavation of floodplain surfaces to expand active riparian area and decrease hydraulic
energy during flood conditions; and
• Excavation of secondary channels to move water further into the floodplain during high
flow events.
All opportunities identified will be accompanied by a discussion of any relevant requirements and
constraints.These may include,but will not be limited to,the following:
• Property ownership limitations;
• Heavily altered late-summer hydrological conditions;
• Permitting requirements;
• Order of magnitude budget estimation;
• Ongoing maintenance requirements;
• Water rights implications;and
Project Proposal /_
3 of 6litlIN
• FEMA floodplain mapping considerations.
The 2D hydraulic model produced in Task 4 maybe used to evaluate potential outcomes associated
with any given opportunity.
Staff from the U.S.Forest Service (USFS) will be engaged in the discussion of project opportunities
since USFS previously indicated some desire to use any work completed at TCOS as a
demonstration project for increasing climate resiliency in similar waterways across the region.
Task 6: Final Reporting and Presentations
This Task includes development of all final reporting materials and two meetings/presentations to
stakeholders.Both meetings will include Pitkin County OST staff and members of the Crystal River
Working Group.The first meeting will be scheduled to occur after completion of Task 5 and prior to
finalization of the conceptual plan.Participants will be invited to review a drafter version of the
conceptual plan and provide feedback.The second meeting will occur following completion of the
final deliverable This meeting will be used to clarifies how recommendations/concerns elevated at
the first meeting were incorporated into the final deliverable.A brief presentation of the content
included in the final deliverable will also be made.
3.0 Expected Results and Deliverables
This effort will produce a conceptual bank stabilization/riparian enhancement plan.The plan will
discuss existing ecological,hydrological,and fluvial geomorphological conditions at the site,
opportunities for enhancing ecological conditions and functions,and the potential budget,legal,
permitting and other constraints associated with those opportunities.The plan will include maps,
renderings,and graphics and will be delivered to Pitkin County in digital form as a single document
with appendices.
4.0 Budget
This project will be completed for a not-to-exceed total of$21,545.00 (TWENTY-ONE THOUSAND
FIVE HUNDRED FORTY-FIVE DOLLARS AND NO CENTS).The project will be invoiced to Pitkin
County OST monthly on a time and materials basis.A breakdown of the budget associated with each
task is presented in the table below.Any requests made by Pitkin County OST for alteration of the
scope of work will require a concomitant modification of the budget presented here.

electronically to you through your DocuSign user account all required notices, disclosures,
authorizations, acknowledgments, and other documents that are required to be provided or made
available to you during the course of our relationship with you. To reduce the chance of you
inadvertently not receiving any notice or disclosure, we prefer to provide all of the required
notices and disclosures to you by the same method and to the same address that you have given
us. Thus, you can receive all the disclosures and notices electronically or in paper format through
the paper mail delivery system. If you do not agree with this process,please let us know as
described below. Please also see the paragraph immediately above that describes the
consequences of your electing not to receive delivery of the notices and disclosures
electronically from us.
