1.0 INTRODUCTION
1.1 GENERAL
The purpose of this "Conditional Letter of Map Revision for Glenwood Springs River Trail,
Atkinson Canal Segment, Section 3" is to establish the proposed 100 year floodplain limits and Base
Flood Elevations (I-percent annual chance), and 100 year Floodway limits for the Roaring Fork
River adjacent to the proposed Atkinson River Trail that runs beside the Roaring Fork River. The
proposed bike/pedestrian trail extends from the Roaring Fork River and the Three Mile Creek
confluence to the 27th Street Bridge (Sunlight Bridge) within the City of Glenwood Springs, Garfield
County, Colorado. The proposed trail discussed in the CLOMR begins at the Roaring Fork River
and Three Mile Creek confluence and ends at the 271h Street Bridge (Sunlight Bridge). The proposed
bike/pedestrian path extends approximately I-mile along the Roaring Fork River and is located in
Sections 21 and 22, Township 6 South, Range 89 West of the Sixth Principal Meridian. See Figure 1
for Vicinity Map.
The proposed development is shown on FEMA's FIRM map for the City of Glenwood Springs,
Community Number 080071, Panel number 1434C, and effective date October 15, 1985. On the
effective FIRM, the Roaring Fork River was studied by detailed methods throughout the section of
interest. The proposed development is in Zone A4, Zone A6 and Zone C. Zones A4 and A6 are
defined as areas of 100-year flooding with base elevations and flood hazards determined. Zone C is
defined as area with minimal flooding. See Figure 2 -Existing FIRM Maps.
High Country Engineering, Inc. (HCE) utilized the HEC-2 analysis from the City of Glenwood
Springs' Flood Insurance Study to establish the "duplicate effective model". The "duplicate effective
model" was updated with topographic information surveyed by HCE in October 2008, to determine
the "existing model".
The study limits for this CLOMR will tie into FEMA Section N-#34 and continue upstream to just
downstream of Section W-#46. This CLOMR includes proposed topographic cross sections of the
Roaring Fork River due to the proposed placement of fill within the floodplain for the construction
of the proposed bike/pedestrian path. The increase in the proposed base flood elevations are less than
one foot above the existing base flood elevations (per HCE's existing conditions). The proposed
hydraulic analysis utilized HEC-RAS, Version 4.0 for determining water surface elevations,
velocities and floodplain limits.

2.0 HYDROLOGY
2.1 GENERAL
This CLOMR application is utilizing the hydrology presented in the City of Glenwood Springs'
Flood Insurance Study (FIS). The FIS's hydrologic analysis was based on stream gaging stations
along the Roaring Fork River. The following recurrence intervals were analyzed in the FIS: 10-year,
50 year, 100 year and 500-year floods. The table below presents the peak discharge for the various
storm events.
Table 1. Storm vs Dischar2c
Recurrence Interval (yr) Peak Flowrate (cfs)
10 13,700
50 19,000
100 21,200
500 28,000
The vegetation within the basin generally consists of native grasses and willows within the Roaring
Fork River floodplain. The soil type within the study limits is predominantly Hydrologic Soils
Group 8, according to the National Resources Conservation Service (NRCS) soils classifications.
3.0 HYDRAULIC ANALYSIS
3.1 HEC-RAS
The computer program USACE's HEC-RAS, version 4.0, was utilized to determine the existing and
proposed 100-year floodplain limits, floodway limits, velocities and water surface elevations. See the
Exhibits provided in the appendices of this report for the floodplain limits for the Atkinson River
Trail based on existing and proposed conditions.
The study limits for this CLOMR will tie into FEMA Section N-#34 and continue upstream to
Section W-#46. The proposed 100-year water surface elevations are less than one foot rise over the
pre-project base flood elevations.
The existing topographic information for the study limits is based on field survey data performed in
October 2008. The existing topography data provided by HCE only extends along the west side of
the Roaring Fork River where the proposed bike/pedestrian path will be located.
The effective mapping shows that the proposed Atkinson River Project is in Zones A4 and A6,
which are defined as areas of 100-year flooding with base elevations and flood hazards determined
and Zone C, which is defined as areas with minimal flooding. The HEC-RAS analysis in the FIS was
used as the .. duplicate effective" model, which is provided in Appendix A. The "existing I pre-
project" model utilized the "duplicate effective" model with updated topographic information to
establish the pre-project 100-year floodplain limits and elevations. The "existing I pre-project" model
is provided in Appendix 8.

PAGE 8 GLENWOOD SPRINGS RIVER TRAIL CONDITIONAL LETTER OF MAP REVISION
The proposed topography is based on the final grading plans for the Atkinson River Trail. The HEC-
RAS analysis for the "post-project" model is provided in Appendix C.
The normal contraction coefficient is 0.2 and expansion coefficient is 0.5. At bridges, the contraction
coefficient is also 0.2 and the expansion coefficient is 0.5.
The starting water surface elevation was based on the "known water surface elevations" supplied by
the FIS's HEC-2 model.
The Manning's roughness coefficient used in the channel is 0.043 and the over bank areas are 0.1.
Photo documentation of the floodplain and channel is included in Appendix C. The river bed has
small cobbles and boulders in the flow line. The overbank areas consist of native grasses and patches
of trees and portions of the Atkinson Canal.
Cross sections were added to the existing and proposed models where proposed pedestrian/bike path
bridge piers are proposed to be located to determine the affects that the proposed piers have on the
base flood elevation. These sections are identified as sections 34.2 and 36.1. A cross section was
also added to determine the point of"no-rise" along the Roaring Fork River. This cross section is
identified as section 40.1.
Sediment transport was not considered in this reach. The previous floods showed some debris was
transported downstream, but minimal sediment was accumulated. The City of Glenwood Springs
has not identified blockage of the bridge caused by debris nor ice jamming being a problem in the
past.
3.2 PROPOSED IMPROVEMENTS
The proposed Glenwood Springs River Trail, Atkinson Canal Segment, Section 3 consists of a
proposed concrete bike/pedestrian path and drainage facilities. Erosion Control blankets and erosion
control logs will be installed to mitigate potential impacts to the Roaring Fork River from developed
storm water flows. The fill placed will need to be armored with riprap to protect the stream bank from
erosion. The following table compares the 100-year water surface elevation for existing versus the
proposed conditions:

3.3 FLOODW A Y ANALYSIS
The floodway is the area of the stream channel and potentially portions of the overbank area that
must be kept free of encroachment so that the base flood can be conveyed without increasing the
water surface elevation by more than one foot. The flood way presented in this CLO MR are based on

the floodway detenninations in the FIS, which is assuming equal-conveyance reduction from each
side of the floodplain up to the top of banks for the main channel.
3.4 FEMA FIRM MAPPING
The site is shown on FEMA' s FIRM map for the City of Glenwood Springs, Community Number
080071, Panel number 1434C, effective date October 15, 1985. On the effective FIRM, the Roaring
Fork River was studied by detailed methods downstream ofthe Section W (#46) at the Roaring Fork
River and Three Mile Creek confluence. The proposed development is mostly in Zone C, but
portions of the proposed construction are located within Zones A4 and A6.
3 .5 VERTICAL DATUM
The vertical datum for this floodplain study and topographic field surveys are based on the National
Geodetic Vertical Datum (NGVD) of 1929. The project benchmark is U .S.G.S. benchmark"Q 158"
(NGVD 1929 elevation = 5957.45').

3. Pre.Submittal Review of Hvdraulic Models
DHS-FEMA has developed two review programs, CHECK-2 and CHECK-RAS, to aid in the review of HEC-2 and HEC -RAS hydraulic models,
respectively . These review programs may help verify that the hydraulic estimates and assumptions in the model data are in accordance with
NFIP requirements, and that the data are comparable with the assumptions and limitations of HEC-2/HEC-RAS . CHECK-2 and CHECK-RAS
Identify areas of potential error or concern . These tools do not replace engineering judgment. CHECK-2 and CHECK-RAS can be
downloaded from http ://www,fema.gov/plan/prevenUfhmlfmJ soft.shtm . We recommend that you review your HEC-2 and HEC-RAS models with

The energy loss was greater than 1.0 ft (0.3 m). between the current and previous cross
section. This may indicate the need for additional cross sections.
During the standard step iterations, when the assumed water surface was set equal to critical
depth, the calculated water surface came back below critical depth. This indicates that there
is not a valid subcritical answer. The program defaulted to critical depth .

0.7 or greater than 1 .4 . This may indicate the need for add i tional cross sections.
The energy loss was greater than 1 .0 ft (0 .3 m). between the current and previous cross
section . This may indicate the need for additional cross sections.

warning: The energy equation could not be balanced within the specified number of iterations. The
pro9ram used critical depth for the water surface and continued on with the calculations.
warning: Divided flow computed for this cross-section.
Warning: The velocity head has changed by more than 0.5 ft (0.15 m). This may indicate the need for

The conveyance ratio (upstream conveyance divided by downstream conveyance) is less than
0.7 or greater than 1.4. This may indicate the need for additional cross sections .
The energy loss was greater than 1 .0 ft (0 .3 m). between the current and previous cross
section . This may indicate the need for additional cross sections .

warning:
warning: During the standard step iterations, when the assumed water surface was set equal to critical
depth, the calculated water surface came back below critical depth. This indicates that there
is not a valid subcritical answer. The program defaulted to critical depth.
