Re: Floodplain Development Permit Application for the Crystal River Hatchery Restoration Project
To whom it may concern,
Introduction
The purpose of this memorandum is to request a Floodplain Development Applications approval from the
Garfield County for the Crystal River Hatchery Habitat Restoration Project (Project). RiverRestoration
has been hired to perform engineering design services for the Project by Colorado Parks and Wildlife
(CPW) is the applicant for the floodplain development and also the land owner.
Project Description
The Project proposes improvements along 300 feet of the Crystal River in Garfield County, Colorado.
The Project is located approximately 250 feet downstream of the Highway 133 crossing and
approximately 330 feet upstream of the Mt Sopris Ranch Rd crossing. Proposed improvements to enhance
the area include:
Re-grading of the existing riverbed to establish a more-distinct thalweg;
Construction of four boulder vane structures to focus low flows and maintain mobility of
incoming substrates during high flow;
Using native alluvium to backfill around boulder vanes;
Installing habitat boulders near the new thalweg to promote holding areas within the reach.
Planting of willow stakes along disturbed banks
Restoration of construction access to pre-project conditions
Total permanent change to the channel has an area of 0.3 acres. Disturbance area of the project during
construction is 0.9 acres, including all staging, construction access, and stockpile areas.
Section 3-301 Compliance (only applicable sub-sections are listed)
A. Use Restrictions in Floodplain Overlay
Of the available categories, the project fits best in “Bank Restoration and Stabilization”. This type of
work is permitted in Floodways and 100-year floodplains as long as there is compliance with all other
applicable standards of the Code.
B. General Standards
Proposed improvements, including vane structures and backfill will be constructed with stable boulder
and native. Materials were selected and sized and will be placed to prevent floatation, collapse or lateral
movement. These materials will be resistant to flood damage.

PO Box 248 Carbondale, CO 81623 (970) 947-9568
D. Floodway
A “No-rise” Evaluation and Certification Letter is included in this submittal as part of a separate memo.
(Floodplain Compliance for Crystal River Hatchery Habitat Restoration Project, Dated July 17, 2021)
In summary: RiverRestoration asserts that a detailed floodplain analysis is not necessary for this project.
The proposed channel has a net cut of 74 cubic yards compared to existing conditions. These project
related reductions in fill and cross section will provide additional conveyance through the project reach.
Admittedly this additional conveyance will be minimal as compared to the total flow in Crystal River
during the 100-year flood event. In conclusion, the proposed project will not create a rise in water surface
elevations associated with the 100-year floodplain of the Crystal River or change the extents of the 100-
year floodplain boundary.
E. Standards for Areas of Shallow Flooding
Hydraulic modeling and evaluation of flow rates ranging from low-flow conditions up to the 100-yr flood
flow have been performed. The results of this evaluation indicate that proposed Project would not result
in an increase in areas of shallow flooding, or in drainage that would adversely impact adjacent
properties.
G. Alteration of a Water Course
A “No-rise” Evaluation and Certification Letter is included in this submittal as part of a separate memo.
(Floodplain Compliance for Crystal River Hatchery Habitat Restoration Project, Dated July 17, 2021)
Section 4-109 Compliance (only applicable sub-sections listed)
The project is in compliance with Section 3-301, Floodplain Overlay Regulations. A “No-rise” Evaluation
and Certification Letter is included in this submittal as part of a separate memo. (Floodplain Compliance
for Crystal River Hatchery Habitat Restoration Project, Dated July 17, 2021). See additional explanation
in the response to 3-301.C above.
The project seeks to improve low-flow connectivity and habitat for fish within the specified location of
the Crystal River. By its nature, it is required for the project to be at its proposed location. The project
will not impact adjacent property owners.
Based on this analysis, there would be no danger to life and property due to flooding or erosion damage;
the would be no danger of materials being swept onto other lands, resulting in injury; the proposed project
would be compatible with existing and anticipated development; there would be no impact to the property
in times of flood for ordinary and emergency vehicles; there would be no impact to the costs of providing
governmental services during and after flood conditions, including maintenance and repair of streets and
bridges, and public utilities and facilities such as sewer, gas, electrical, and water systems; the would be
no change in the heights, velocities, duration, rate of rise, and sediment transport of flood waters that
would pose increased risk of damage or risk to public safety; there would be no impact of the necessity to
the facility of waterfront location; there are no alternate locations not subject to flooding or erosion
damage for the proposed project; and there is no impact to the comprehensive plan for the area.

Section 4-203 Compliance (only applicable sub-sections listed)
Based on my review, construction drawings meet requirements of section 4-203.
A. Professional Qualifications
The project was designed under direction and guidance of a Professional Engineer in the state of
Colorado, license #51284.
B. General Application Materials
See attached documents for the general application materials submitted as part of this Floodplain
Development Application.
C. Vicinity Map
See attached vicinity map showing the location of the project on the Crystal River just upstream
and of Carbondale, CO.
D. Site Plan
See attached plan set (Crystal River Hatchery Habitat Restoration Project, Dated August 2021)
for the Site Plan and the required elements.
E. Grading and Drainage Plan
See attached plan set (Crystal River Hatchery Habitat Restoration Project, Dated August 2021)
for the Grading and Drainage Plan and the required elements. Project specifications are available
upon request.
Construction Schedule:
Bid advertisements are expected to be issued in summer of 2022, mobilization in early-mid
August, and in-river work between August 15 and October 1, 2022. The project is expected to be
completed by the end of 2022
Permanent Stabilization:
Proposed boulder and placement of native alluvium has been designed and modeled to remain
stable over regular and flood flow conditions. Vane structures will be keyed into existing banks.
Erosion and Sediment Control:
Erosion and Sediment Control (ESC) BMPs will be implemented to minimize impacts to the
Crystal River and its riparian area. These BMPs include access ramps, silt fence, oil booms,
turbidity curtains, and dewatering filters. See the CW Sheets in the attached planset for more
details on the ESC plan.
Estimated Cost:
The total estimate construction cost for the project, including soft costs and contingency is
$150,000. Complete engineer’s cost opinion is available upon request.
Stormwater Management Plan:
The site is less than 1 acre, so a Stormwater Construction Permit issued by CDPHE is not
required. The contractor will be required to submit for and receive a construction dewatering
permit through CDPHE.
Reclamation, Revegetation and Soil Plan:
Willow staking along disturbed banks will be done upon completion of proposed grading. The
harvesting and installation of the willow stakes are described in the plans and specifications.
Construction access will be restored to pre-project conditions to the satisfaction of CPW (owner).

Re: Crystal River Hatchery Habitat Improvement Project
To Whom it May Concern,
Colorado Parks and Wildlife (CPW) is working toward improving the aquatic habitat in the
Crystal River on property owned by the State of Colorado, CPW at the Crystal River Hatchery
and Brood Unit. This section of river has historically been plagued by severe cobble deposition
resulting in insufficient fish passage. CPW has contracted with River Restoration to design and
implement this project. As a part of this process River Restoration is representing CPW in the
submission of permit applications. Please reach out to me with any questions you may have.
Sincerely,

RE: Floodplain Compliance for Crystal River Hatchery Habitat Restoration Project –
Garfield County, CO
Dear Mr. Hartmann,
The Crystal River Hatchery Habitat Restoration Project (Project) involves improvements along
300 feet of the Crystal River in Garfield County, Colorado. The Project is located approximately
250 feet downstream of the Highway 133 crossing and approximately 330 feet upstream of the
Mt Sopris Ranch Rd crossing. A vicinity map of the Project is shown in Figure 1, below.
Proposed improvements to enhance the area include:
Re-grading of the existing riverbed to establish a more-distinct thalweg;
Construction of four boulder vane structures to focus low flows and maintain mobility of
incoming substrates during high flow;
Using native alluvium to backfill around boulder vanes;
Installing habitat boulders near the new thalweg to promote holding areas within the
reach.
Planting of willow stakes along disturbed banks
Restoration of construction access to pre-project conditions

Floodplain Compliance | Crystal River Hatchery Habitat Restoration Project 2
The project reach currently has areas of poor connectivity and aquatic habitat during low flow
periods. The channel expands directly downstream of the Highway 133 Bridge and forms a wide
cobble riffle; this area has been identified through site investigation and existing conditions
hydraulic modeling as the focus of the proposed improvements for the project. A deep pool exists
upstream of this riffle, near the bridge, and a more-distinct run with deep holding areas exists
downstream of this riffle. The project seeks to promote low-flow connectivity and improve habitat
throughout this riffle to connect the two areas that currently have good or adequate low flow
conditions for the local fish community. The Project would achieve these goals without increasing
post-project 100-yr water surface elevations (WSE) above the existing condition 100-yr Water
Surface Elevations (WSE).
The one-dimensional hydraulics analysis discussed in this floodplain compliance letter was
performed using the USACE’s HEC-RAS v5.0.7.
Hydrology
Hydrologic input to the HEC-RAS hydraulic models was obtained from FEMA’s Flood Insurance
Study (FIS) for unincorporated Garfield County, revised effective date August 2, 2006 as well as
the Town of Carbondale FIS report, effective date February 5, 1986. The Project is located near
the upstream corporate limits of the Town of Carbondale, where the Crystal River experiences a
100-year discharge of 7,410 cfs. No additional hydrologic investigation was performed as part of
this analysis. A copy of the relevant pages of the FIS discussing hydrology is included as Exhibit
1.
Existing Conditions
The Effective Base Flood Elevation (BFE) profile was obtained from the FIS report and the
Unincorporated Garfield County FIS report, revised August 2, 2006. The water surface elevation
(WSE) profile in these reports represents the most current FEMA data for the Crystal River within
the project reach. The cross-section locations of this model were obtained from the current FEMA
Flood Insurance Rate Maps. The FIS cross-sections that were modeled for this evaluation are cross
sections R, S, T, U, V, W, and X. FIS cross station-elevation data were not available, so an existing
conditions HEC-RAS model of the project reach was developed using LiDAR data received from
the State of Colorado’s Office of Information Technology in 2018 and recent topographic and
hydrologic survey data collected by RiverRestoration in 2021. Please note the Mt. Sopris Ranch
Rd. bridge, located between FIS cross sections T and U as well as the Highway 133 Bridge located
between FIS cross sections V and W are not included in the Effective model. These bridges were
added to the Existing Conditions Model, along with four other additional cross sections to
represent the proposed actions.
The 100-year flow rate of 7,410 cfs was used as the upstream boundary condition. The WSE at the
downstream end of the model was taken from the FIS report. The effective BFE profile is in the
vertical datum National Geodetic Vertical Datum of 1929 (NGVD 29); therefore, a vertical shift
of +4.46 feet was applied to convert elevations to into the project’s vertical datum, North American
RF.STORATION .ORG
PO Box 248 Carbondale, CO 81623 - (970) 947-9568
Floodplain Compliance | Crystal River Hatchery Habitat Restoration Project 3
Vertical Datum of 1988 (NAVD 88). This datum shift was determined using the USACE’s
Corpscon v6. An output of the conversion is included as Exhibit 2.
To evaluate the effects of the project, cross-sections were added upstream and downstream of the
proposed improvements, as well as within the proposed grading to represent the impacts of the
project. These cross-sections were updated with topographic and bathymetric survey data
discussed above. Roughness values were adjusted within the limits specified in the FIS report for
the existing conditions model to calculate a WSE profile similar to the BFE profile published in
the FIS report. Attached Exhibit 3 shows a plan view of the HEC-RAS cross sections that were
evaluated for the Project.
Proposed Conditions
A Proposed Conditions model was developed by modifying the existing conditions model to
represent the channel under proposed conditions. Cross section locations, boundary conditions and
other modeling assumptions were kept from the Existing Conditions model.
To demonstrate compliance with Garfield County and federal floodplain development guidelines,
100-year flood elevations calculated from the Proposed Conditions model were compared to the
Existing Conditions model and the Effective BFEs published by FEMA. Energy Grade Lines
(EGL) were also calculated and compared. No increases in the 100-year WSE or EGL were
observed. See Table 1, Table 2, and Exhibit 4 (attached) for a tabular and graphical comparison of
these results.

Conclusion
Based on the evaluation and comparison of HEC-RAS modeling results described in this letter, the
100-year water surface elevation and energy grade line are not anticipated to increase because of
the Project. The results of this analysis demonstrate that the Proposed Conditions is not anticipated
to adversely affect adjacent properties or increase the elevation or quantity of flood waters over
Existing Conditions.
The Crystal River Hatchery Habitat Restoration Project is expected to improve low-flow depth
connectivity and enhance aquatic habitat within the project reach without posing a threat to public
safety. Based on the results presented in this report, RiverRestoration has determined that the
Project complies with Garfield County floodplain development guidelines.
