WARNER CREEK OPEN CHANNEL STUDY
SCOPE OF WORK
JERRY PARCHE' CONSULTING ENGINEERS
STUDY NO. SWS-011
Preface
Over the years, the City of Fort Worth has experienced growth and development
throughout. As a result, some of the current floodplain delineations and studies may be
outdated. Some streams within the City were never studied in detail. The purpose of
these open channel studies is to assess the existing conditions of select open channels
and to develop a master plan of improvements as needed. The existing conditions
analysis includes detailed hydrologic and hydraulic analyses to determine probable
flooding areas during exceedance storms and a comparison of results to existing
studies (if available). The revision or development of a master plan of improvements for
the study area will include a set of conceptual improvement alternatives to minimize
flood impacts to homes and buildings. These studies may require the submittal of a
LOMR to FEMA if the resultant flood analysis is significantly different from the current
flood insurance study delineation and base flood elevations. Because of the number of
studies that will be conducted, the City would like to develop a standardized approach
for consistent data management and model development. The City has embarked on
the development of a GIS inventory of the existing storm water management system.
These studies will have data that will be relevant to the City's ongoing GIS inventory.
Therefore, the submittal of GIS data to the City is required. For data management
purposes, all of the reports and detailed analyses will be submitted to the City in an
approved format. A standardized approach to documentation, submittals and approach
will assist the City with data management of these and future studies.

Task 2: Data Search, Collection, Field Reconnaissance, Stream Condition
Assessment, and Surveys
a. Dataset Search and Collection
The City of Fort Worth will provide the ENGINEER with the following watershed data in
GIS format, in addition to the available models and reports: stream centerlines, street
centerlines, 2007 aerial imagery, 2007 terrain surface in LAS format, existing and future
land use data, 2007 subbasin delineations (may not be delineated for each site), high-
water marks (if available), and zoning maps. Historical rainfall data and the as-built
drawings of the hydraulic structures may be available from the City. The ENGINEER
shall submit a written request to FEMA for all relevant available data from the effective
Flood Insurance Study (FIS) including but not limited to: LOMRs, hydrologic and
hydraulic data, reports, working maps, etc. The City shall determine the extent of the
study along the stream.
The ENGINEER shall use the City-provided watershed description, stream centerline,
and 2007 terrain surface as part of the base data for modeling and mapping. If
necessary, the ENGINEER may modify the stream centerline alignment during Tasks 3
and 4 according to topography, 2007 aerial imagery, or new survey data. Any errors
identified or revisions made to the City's stream centerline and watershed boundary
datasets shall be reported and discussed with the City's Project Manager.
The ENGINEER will review and identify known flooding and drainage issues referred to
as "hot spots" within the study area. The City will provide available drainage complaint
reports to the ENGINEER. The identified "hot spots" shall be compiled into a GIS
geodatabase.
ATTACHMENT"A"
Page 3 of 19
The City of Fort Worth's Storm Water Management Division shall assist the ENGINEER
in locating required data available from the City, but the ultimate responsibility for
identifying data needs and for finding, collecting, developing, analyzing, and creating all
necessary data shall reside with the ENGINEER. If required data is unavailable, the
ENGINEER shall inform the City in writing and discuss with the City's Project Manager
for actions or determination.
b. Field Reconnaissance
The ENGINEER shall perform field reconnaissance to become familiar with the main
stem and the appropriate tributaries, the hydraulic and hydrologic structures, land use,
vegetative cover conditions of the floodplain, and special features and problems within
the watershed. The ENGINEER is aware that not all natural channels are contained
within City easements therefore property owner permission must be obtained by the
ENGINEER to access private property. The ENGINEER shall document their
reconnaissance efforts findings with labeled digital photographs. Typical channel and
over-bank types shall be photographed and labeled with location and Manning "n" value
assumptions.
The ENGINEER shall document physical characteristics of the watershed relevant to
modeling, including but not limited to: specific features of all major detention ponds and
outlet discharge structures, vegetative and built structure conditions along the
floodplains, types and number of hydraulic structures involved, apparent maintenance
condition of channels, over-banks and existing hydraulic structures, locations and
descriptions of stream cross-sections to be surveyed (including bridge railings and
obstructed flow areas).
c. Stream Condition Assessment
The ENGINEER shall perform a stream condition assessment as a result of field
reconnaissance efforts and document the locations of observed erosive conditions,
channel stability issues, channel side-slope failure, failed channel protection, sediment
transport, and/or other observed failures. The ENGINEER may assign a rating of
"Excellent", "Good", "Fair", or "Poor". The ENGINEER shall document the stream
conditions assessment efforts with labeled digital photographs. The ENGINEER shall
populate a GIS geodatabase of identified areas of concern.
d. Field Surveys
All bridges, culverts, and critical stream cross-sections (having substantial change in
channel geometry and/or bed slope in contrast to upstream or downstream cross-
sections) should be surveyed. The field surveys shall include any headwalls and
outfalls along the channel. The maximum stream length distance between any two
surveyed cross-sections shall not exceed approximately 1,500 feet. The City's Project
Manager shall review the number of open channel cross-section and hydraulic structure
surveys prior to a final scope of work. [The ENGINEER is to include the number of
open channel cross-section and hydraulic structure surveys in the final scope.] The
ENGINEER shall follow the current version of FEMA Guidelines and Specifications for
ATTACHMENT"A"
Page 4 of 19
Flood Hazard Mapping Partners Appendix N: Data Capture Guidelines to collect field
survey data for open sections, bridges, culverts, and dams.
Benchmarks shall be located and recorded for survey control. Available elevation
reference marks shall be located and recorded at surveyed hydraulic structures. If
elevation reference marks can not be located, they may be set at each surveyed
hydraulic structure as a chiseled mark in a headwall, wingwall, bridge deck, etc in a
manner suitable for future reference. The ENGINEER shall establish primary and
secondary control points for survey. Primary control points are typically iron rods that
are suitable for future reference. Secondary control points are set at each surveyed
cross-section and are intended to establish the primary control data at each cross-
section. Secondary control points are typically nails and are not intended to be
permanent. The current version of FEMA Guidelines and Specifications for Flood
Hazard Mapping Partners Appendix N: Data Capture Guidelines shall be used a guide
to setting elevation reference marks.
Field surveys of stream cross-sections shall be representative of the natural ground of
the channel and overbanks. Surveys of bridges, culvert, dams or other hydraulic
structures shall be representative of the hydraulic structure's geometry. A typical
ground cross-section shall be surveyed upstream of the structure. Measurements and
survey points defining the geometry of the hydraulic structures shall all be recorded in
field notes.
Field survey notes shall represent graphically and clearly, in plan and profile view, what
was surveyed, photographed, and recorded. All of the sketches should depict the
upstream face of the structure as well as the direction of flow.
Digital photos shall be taken at each surveyed stream cross-section looking upstream
and looking downstream at the channel. Photos of the upstream and downstream faces
of the hydraulic structures shall be taken along with the upstream and downstream
channel. Wherever possible, the pictures should contain the entire face of the structure.
The ENGINEER will use the survey codes and format outlined in the FEMA Guidelines
and Specifications for Flood Hazard Mapping Partners Appendix N: Data Capture
Guidelines for survey text files. The text files shall include point number, northing,
easting, elevation, and description. The ENGINEER shall submit the survey data as
text files and in a GIS shapefile format.
It is the responsibility of the ENGINEER to obtain property owner permission to perform
surveys outside of City easements. The ENGINEER shall notify the local property
owners that surveys and field reconnaissance will be conducted for a certain period
time.
e. Finished Floor Elevations
The ENGINEER shall determine the finished floor elevations and lowest adjacent
grades of buildings and residential homes within the current effective floodplain and
ATTACHMENT"A"

GIS files, field notes, and ASCII text files.
• One set of CD/DVDs containing electronic versions of all information
(intermediate and final data and photos) gathered in this Task.
Task 3: Development of Detailed Hydrologic Models
The ENGINEER shall develop detailed existing land-use conditions (and/or ultimate-
development land-use conditions based on 2009 comprehensive plan if applicable)
HEC-HMS models for the watershed. The City will determine if ultimate development
land-use conditions are warranted for the study. The ENGINEER may use HEC-
GeoHMS as a preprocessor to provide base information for the new hydrologic model.
The hydrologic model shall be fully geo-referenced for seamless incorporation into the
City's GIS inventory. The ENGINEER shall fully annotate the HEC-HMS model,
including descriptive comments in all relevant fields, and clearly label the simulation
runs with respect to the return period. The ENGINEER shall coordinate any occurrence
of inter-basin transfer of flow with the City's Project Manager. If knowledge of inter-
basin transfer of flows is known during the preparation of the scope, the ENGINEER
shall provide details on how the hydrology and hydraulics will be modeled.
The ENGINEER shall use the 2-, 5-, 10-, 25-, 50-, 100-, and 500-year return events to
develop hydrologic and hydraulic models, water surface elevation profiles, and
floodplain maps. If the basin is fully developed then ultimate land-use conditions will be
assumed as "Existing Conditions". The ENGINEER shall model the 100-yr return event
for ultimate conditions if existing conditions in the basin are not fully developed. The
ENGINEER shall use representative historical rainfall data to perform hydrological
analysis to perform a high water mark simulation/validation with hydraulic models.
a. Rainfall
The ENGINEER shall use a 24-hour duration storm (SCS Type 11 or frequency) for the
meteorological model and shall use the City of Fort Worth Storm Water Management
Design Manual Appendix A rainfall depth-duration-frequency tables.
b. Data Sources
The ENGINEER shall review the current effective hydrologic and hydraulic models,
Letters of Map Revision (LOMRs) approved after the current effective FIS study and
City of Fort Worth land development projects and incorporate them into the study as
appropriate.
ATTACHMENT"A"
Page 7 of 19
The ENGINEER may obtain "as built" drawings from the City (if available) for
constructed regional ponds and other large residential and commercial ponds to be
modeled. The stage-storage-discharge (SSD) rating curve for these ponds used in the
model shall be verified as being accurate. If necessary, the SSD curves may be re-
developed. In all cases, the SSD rating curve shall be the same for both the hydrologic
and hydraulic models.
The existing land-use conditions data, the 2009 projected future (ultimate) development
land-use conditions data, topographic data (2007 ACS surface data), and the latest
Natural Resources Conservation Service (NRCS) Soil Survey Geographic (SSURGO)
database shall be used in the hydrologic model development.
c. Model Development
The ENGINEER shall coordinate watershed boundaries with other concurrent studies.
The subbasin size shall not exceed one-third of a square mile. Use of larger subbasins
shall be discussed with the City's Project Manager. Break points (junctions) may be set
at certain locations if requested by City's Project Manager. The ENGINEER shall
conduct a "working session" with City staff to finalize watershed basin boundaries and
junctions.
If a conflict exists on a watershed boundary determination, it is usually the topographic
data, not the storm drain system, that determines the watershed boundaries. However,
if storm drain trunk lines or any other diversion/by-pass hydraulic structures exist in the
watershed and divert a significant amount of flow from one basin to another, those
hydraulic structures shall be modeled in the study.
The SCS unit hydrograph shall be utilized for developing the HMS model.
The TR-55 equations and curves for estimating the time of concentration for overland
(sheet) flow, shallow concentrated flow, and channel flow shall be used. Overland
(sheet) flow length shall be no more than 50 — 100 feet for urban land-use conditions.
The ENGINEER shall delineate and depict the longest flow path per subbasin and
include the length and time of concentration per segment.
The SCS curve number method shall be used for loss rate estimation. The ENGINEER
shall prepare a table of impervious cover percentages and curve numbers for various
land uses and soil conditions based on the City of Fort Worth Storm Water Management
Design Manual. The runoff curve numbers for open space and undeveloped areas shall
be based on the cover type and hydrologic condition of "Open Space, Good Condition."
The composite curve number for each subbasin shall be computed based on a
composite percentage of soil types.
For modeling the existing land-use conditions of a suburban watershed, the impervious
cover percentage shall be determined based on zoning districts. Impervious cover
percentages per zoning district are listed in Table 1.
ATTACHMENT"A"
Page 8 of 19
The ENGINEER shall use the NCTCOG existing land-use spatial data and City 2007
aerial imagery to confirm that the current zoning districts have an accurate land use
assignment. It is the ENGINEER's responsibility to properly determine the impervious
cover percentage for sparsely located farmland houses which may or may not be
directly connected to a surface drainage system. The ENGINEER shall use the City
2009 comprehensive plan to determine the impervious cover percentage for ultimate
conditions for future growth and development. The composite impervious cover
percentage and soil-based composite runoff curve numbers for each subbasin shall be
summarized in a table of subbasin parameters.

d. Routing
The ENGINEER shall use the Modified Puls or the Muskingham-Gunge routing methods
to attenuate the runoff hydrograph. Other routing methods shall require the approval of
the City.
e. Depth-Area Analysis
Depth-Area Analysis (areal reduction) shall be used for watersheds with a drainage
area of 9.6 square miles or greater. if necessary, peak flow tables for each return
period and for both existing and future land-use conditions will be provided with peak
flows computed at all subbasin outlets and hydrologic junction points with areal
reduction for drainage areas (in square miles) of 0.0, 10, 20, 30, etc. up to the total
watershed area. The peak discharge will be interpolated based on the drainage area at
the appropriate junction location. The following is an example of the table:

To estimate the 100-year peak flow at the junction J130W, one may code a linear
interpolation formula in an Excel Spreadsheet to linearly interpolate the 100-yr peak flow
at this junction location, e.g., Q(J130W)=21350+(15.767-10)/(20-10)*(20660-
21350)=20952 cfs.
f. Results
The model results shall be compared to available reliable recorded/historical rainfall-
runoff data, including historic storm events. If no reliable recorded/historical rainfall-
runoff data is available, the ENGINEER may run checks with other sources of data such
as the local/regional regression equations, Current Flood Insurance Study, or the
USGS's frequency-based 100-year peak flow versus watershed drainage area curve for
ATTACHMENT"A"
Page 10 of 19
similar watersheds. If significant differences are found, adjustments to the hydrologic
model may be required.
The ENGINEER shall prepare a table of peak flow rates for each of the return events
analyzed. The ENGINEER shall compare the peak flows from the new study to those of
the current effective (if available). The comparisons shall be summarized in the report.
The ENGINEER shall document the methodologies and assumptions for each subbasin,
details of calculating the time of concentration, subbasin and longest flow path
delineations, creek centerline, software, and data sources used, any significant changes
in flows between the old and new hydrologic models with an explanation of differences,
and a table containing peak flows at each subbasin, junction, and pond location with
areal reduction (if applicable), and any special technical issues and resolutions.
Task 3 Deliverables:

annotated HEC-HMS hydrologic model that provides peak flow rates for
the 2-, 5-, 10-, 25-, 50-, 100-, and 500-year floods together with all
supportive GIS and modeling data (including DSS files) for the HEC-HMS
models (current non-beta HEC-HMS version at time of delivery).

ATTACHMENT"A"
Page 11 of 19
Task 4: Development of Hydraulic Models and Floodplain Maps
The ENGINEER will use the latest HEC-RAS model software to develop hydraulic
models for the study. The ENGINEER may use HEC-GeoRAS as a preprocessor to
provide base information to the hydraulic model and as a post-processor to map the
floodplains. The ENGINEER shall fully annotate the HEC-RAS model, including
descriptive comments in all relevant fields, and clearly label the flow data profiles with
respect to return period. Cross-sections or bridge/culvert structures that incorporate
survey data shall include the survey data source, date and hydraulic structure name in
the cross section data description. The ENGINEER may use FEMA's CHECK-RAS
program to do an initial verification of the HEC-RAS models and address the issues it
finds or provide an explanation of why a correction was unnecessary. The hydraulic
model will be fully geo-referenced for seamless incorporation into the City's GIS
inventory.
a. Model Development
The ENGINEER shall prepare the models to run under steady state conditions. The
ENGINEER will meet with the City's Project Manager to determine whether an unsteady
state model is warranted.
Surveyed bridges, culverts, and critical stream cross-sections (having substantial
change in channel geometry or slope) shall be incorporated into the HEC-RAS model.
Other non-critical stream cross-sections shall be cut from the City's topographic data (if
available) or the most accurate topographic data available. The cross-section layout
shall be set in a reasonable manner consistent with the respective DFIRM (if available)
taking into consideration hydraulics and floodplain mapping. As a general guideline,
spacing between any two cross-sections shall not exceed approximately 200 ft unless
directed by the City's Project Manager. The ENGINEER will conduct a "working
session" with the City staff to review cross-sectional cut-line locations and layout. The
ENGINEER will proceed with detailed hydraulics following City's review of the cross-
section cut-line layout or as directed by the City's Project Manager. The ENGINEER
shall discuss with the City's Project Manager whether channel invert interpolation
between surveyed cross-sections is required. Interpolated cross-sections shall be kept
to a minimum. If interpolated cross-sections are used in the development of the
models, each section shall be labeled and described in the model and identified on a
work map of the cross-section layout. The ENGINEER shall describe in the written the
report the purpose of the interpolated cross-sections. All cross-section stations and
reach lengths shall be rounded to the nearest foot.
The ENGINEER shall assign Manning's n-values to a specific channel or over-bank
area based on actual physical conditions using information from field reconnaissance,
aerial photos, and the City of Fort Worth Storm Water Management Design Manual n-
value reference tables. Composite n-values are recommended for the left overbank,
ATTACHMENT"A"
Page 12 of 19
channel, and right overbank. Caution will be exercised not to over- or under-estimate
the "n" values. The composite "n" value in over bank flow areas shall be limited to 0.15.
For any 'In" value exceeding 0.15, the ENGINEER shall inform and discuss with the
City's Project Manager for a final decision. It is recommended that the ENGINEER use
the HEC-RAS functions of "blocked obstruction" and "ineffective flow area" whenever to
enhance the model.
The ENGINEER shall recreate or confirm the limits of the floodway. A floodway will not
be evaluated or created for study areas that do not have an existing floodway.
b. Flow Data
Peak flows computed from a hydrologic model with proper areal reduction (if applicable)
shall be put into the hydraulic model as close as possible in terms of location, e.g.,
subbasin junction location in HEC-HMS versus cross-section location in HEC-RAS. A
table showing the HEC-RAS cross-section flow change locations and the corresponding
HEC-HMS junction name shall be provided. The peak flow shall be the same in both
models. In the case that a creek or channel runs through a subbasin in a hydrologic
model (see an example attached below), the additional outflow from the subbasin shall
be proportionally inserted in one of the following two methods: (Method 1) at 1/3 or at
2/3 of the channel segment within the subbasin, or (Method 2) approximately at middle
of the channel segment (Figure 1).

If the ENGINEER determines that either procedure will not accurately represent the
additional flow between hydrologic analysis points, the ENGINEER shall inform and
discuss with the City's Project Manager flow change locations.
c. Results
If data is available, model results shall be compared with recorded stage levels or
checked against known high water marks. The model results shall also be compared to
known flooding events. If significant differences are found, adjustments to the hydraulic
model may be required.
The ENGINEER shall document all methodologies and assumptions, software used,
data sources, problem areas, and significant changes in water surface elevations
between the old and new hydraulic models.
The ENGINEER will eliminate crossing profiles; however, given the number of profiles
(for existing and future conditions) and the potential for minimal differences in computed
flow rates, it is possible that some minor crossing of profiles cannot be resolved. The
ENGINEER will coordinate these issues with the City staff.
The ENGINEER shall produce an updated or new floodway data table. The lettered
section should correspond with the locations of the effective study,
The ENGINEER will produce water surface elevation profile plots for the 10-, 50-, 100-,
and 500-year flood frequencies using FEMA RASPLOT 2.5 or later. The ENGINEER
shall reference the existing Flood Insurance Study profile plots for plot scale.
The ENGINEER shall delineate the floodway and the 100- and 500-yr floodplains
through the study area. If applicable, the 100-yr floodplain for ultimate conditions will
also be delineated. The ENGINEER shall produce work maps that show the following
minimum information in and near the floodplains: (1) Cultural features, such as
railroads, airfields, streets, roads, public schools, highways, levees, dikes, dams and
other flood-control structures, and other prominent man-made features and landmarks;
(2) Hydrographic features, such as rivers, streams, lakes and ponds, and channels
(including both banks of a stream when graphically possible); (3) Corporate limits,
extraterritorial jurisdiction limits, and boundaries of excluded areas; (4) Elevation
reference marks (ERM), and (5) Grid lines (State Plane North Central Texas Survey
Feet) with appropriate values annotated.
Base Flood Elevations (BFEs) will be generated and shown by wavy line contours
drawn normal to the direction of the flow of water, perpendicular to the floodplain, but
not necessarily perpendicular to the stream centerline. They shall extend completely
across the existing conditions 100-year floodplain. Each BFE notation shall indicate its
elevation (NAVD88) to the nearest whole foot.

master plan of proposed improvements and flood hazard mitigation. Alternatives to be
considered will include but are not limited to open channel improvements, detention,
and property buy-outs and building/house removal. This task will consider flooding
issues identified in Task 5 to determine the potential flood reduction benefits of flood
mitigation. The ENGINEER shall determine appropriate acquisition data based on
current available appraisal district data. [ENGINEER to estimate the number and type
of alternatives to be included in the analysis in conjunction with City Staff.]
The ENGINEER shall develop and discuss realistic preliminary alternatives with the
City's Project Manager prior to analysis. The ENGINEER shall then evaluate the
preliminary alternatives discussed and make necessary revisions. The ENGINEER
shall discuss the revised alternatives with the City's Project Manager before finalizing
the conceptual mitigation alternatives. The alternatives may be finalized prior to the
public meeting discussed in Task 1. City utility crossing potential conflicts shall be
considered and identified in the development of the alternatives.
The ENGINEER shall document all methodologies and assumptions used to analyze
the conceptual flood mitigation alternatives and significant changes in water surface
elevation between the existing conditions model and the improvement alternatives
model. Any modifications to the hydrologic features developed for Task 3 as a result of
the improvements shall be discussed with the City's Project Manager. The ENGINEER
shall rerun routing for the alternatives.
A benefit cost analysis (BCA) shall be conducted using the FEMA Mitigation BCA
Toolkit Version 3.0 (July 2006). The ENGINEER shall use a discount rate of 7% and a
project life of 50 years. The ENGINEER will evaluate the BCA based on the storm
events outlined in Table 1 and the potential damages to residential, commercial, and
industrial structures. The benefit cost analysis may be used to prioritize the mitigation
alternatives. The conceptual opinions of probable cost shall include a contingency cost
of thirty (30) percent and engineering and surveying cost of ten (10) percent.
Task 6 Deliverables:
• Documentation
o A summary of the Task and a description of methodologies and
assumptions used. The detailed summary shall include design criteria,

Mayor and Council Communication
COUNCIL ACTION: Approved on 4/28/2009
DATE: Tuesday, April 28, 2009 REFERENCE NO.: **C-23471
LOG NAME: 20SWMWARNERCHANNELLOMR
SUBJECT:
Authorize an Agreement with Jerry Parche Consulting Engineers in the Amount of$89,500.00 for Warner
Channel Federal Emergency Management Agency Floodplain Re-Mapping Study
RECOMMENDATION:
It is recommended that the City Council authorize the City Manager to execute an agreement with Jerry
Parche Consulting Engineers in the amount of$89,500.00 for the Warner Channel Federal Emergency
Management Agency Floodplain Re-Mapping Study.
DISCUSSION:
In order to address stream flooding, detailed channel studies are required to determine runoff rates and
flow depth, to verify and correct Federal Emergency Management Agency's (FEMA) Flood Insurance Rate
Maps, and to develop a master plan for each stream consisting of channel improvements, detention and
other measures which can remove buildings from the floodplain and make roadway crossings safer. In
November 2007, a request for qualifications was advertised for open channel studies. Twenty-three
statements of qualifications were received and Jerry Parche Consulting Engineers was selected to
prepare the Warner Channel FEMA Floodplain Re-Mapping Study, Storm Water Study SWS-011, which
needs modification of the FEMA map to reflect previous City projects.
The scope of work will include: a detailed study of the stream to reflect current conditions, including culvert
improvements installed in 2006; preparing documents to obtain a FEMA Letter of Map Revision; and,
identification of erosion repair and other minor projects which may be needed. Jerry Parche Consulting
Engineers proposes to perform this study for a lump-sum fee of$89,500.00. City staff considers this fee to
be fair and reasonable for the scope of services proposed, based on the size of the watershed and length
of the stream. The Storm Water Utility Operating Fund will be used to fund this study.
Jerry Parche Consulting Engineers is in compliance with the City's M/ BE Ordinance by committing to 17
percent M/WBE participation. The City's goal on this project is 17 percent.
This project is located in COUNCIL DISTRICT 9.
FISCAL INFORMATION / CERTIFICATION:
The Financial Management Services Director certifies that funds are available in the current operating
budget, as appropriated, of the Storm Water Utility Fund.
