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 As a result, some of the current floodplain delineations and studies may be outdated.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. ATTACHMENT"A" Page 1 of 19 WARNER CREEK OPEN CHANNEL STUDY Project Summary a. Purpose of Study The purpose of this study is to determine design flood frequency peak discharges in Warner Creek, determine flood levels for frequency storms, determine the 100-year flood plain and floodway delineations and analyze flood mitigation alternatives if needed. In addition a Letter of Map Revision will be obtained from the Federal Emergency Management Agency. The ENGINEER's services and products resulting from this study shall be referred to as "Warner Creek Open Channel Study". The ENGINEER shall perform the project services in accord with (1) the Federal Emergency Management Agency floodplain modeling and mapping specifications and guidelines, (2) the City of Fort Worth Storm Water Management Design Manual, and (3) specific requirements and technical guidelines in this scope document. The City of Fort Worth Storm Water Management Design Manual shall be the prevailing document. b. Pertinent Data Warner Creek begins on the west side of 8th Avenue near the intersection with Robert Street.

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 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" Page 5 of 19 anticipated revised areas.

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. Table 1.

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: 100-Year Peak Flows(cfs) Under Existing Land-Use Conditions Drainage Storm S¢C,,rr Storm, Storm Hydrologic Area Area 7Y ,p. r Area Element (sq mi) 0 mi2 ti M 26 al 30 mil J160W 7.576 12140 11610 11150 10770 J160K 8.011 12160 11750 11360 11030 JWCR160 15.587 22230 21460 20770 20190 WCR160 15.587 22070 21320 20620 20020 J1301VV 15.767 22110 21350 20660 20060 JWCR130 17.91 24390 23570 22810 22090 JWCR120 18.364 24820 23990 23210 22470 WCR1100 18.364 24680 23840 23050 22350 JWCR1170 18.78 24790 23950 23160 22450 WCR120 18.78 24730 1 23890 23100 22410 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.

(If applicable) An ArcGIS 9.2 or later version of a personal geodatabase containing all final vector information developed under this task. o Support: Electronic versions of all information gathered, supporting materials and data in developing the hydrologic models, and work products created in this task, such that the models can essentially be duplicated with the backup data. • The ENGINEER shall submit two sets of DVDs containing electronic versions of all information gathered and work products created in this task. 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). r I Flow{QS}from HMS at `the cl-t junction t i f RAS Input way I: I i Q2=Q1,11.= i if 1 Flow(Q4)from WAS at 1 i the nearby junction point I I Hydrologic Junction _ / RAS Input way 2: Q3=Q2+2l3'dQ Q5=Q4+dQ-Qm ' Qm--total peakdiseharge at the outlet of the s bbasin dQ is the net added flow from each flow through subbasin with areal reduction t+ I Figure 1. Flow Change Locations ATTACHMENT"A" Page 13 of 19 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.

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.
