SWS-005 SCOPE OF WORK 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 As a result, some of the current floodplain delineations and studies may be outdated.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 18 GREENFIELD ACRES DRAINAGE MASTER PLAN STUDY NO. 0W0-005 Project Summary NUNrpose %0 Study To conduct a detailed evaluation of approximately 14,273 linear feet of the Unnamed Tributary to Marine Creek Lake and submit a LOMR to FEMA. The ENGINEER'S services and products resulting from this study shall be referred to as 'Greenfield Acres 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 The existing watershed is to the west of Marine Creek Lake in Fort Worth Texas. The Unnamed Tributary referred to herein as the "Greenfield Acres Drainage Master Plan" collects approximately 643 acres of runoff in underground storm water systems and open channels and discharges into Marine Creek Lake. This channel has no current effective FIS or drainage study. Task 1: Project Management The ENGINEER's project management activities shall include task leadership and direction, telephone and written communication, bkmonthly project update meetings, project status reports, project schedule and updates, and personnel and data management among other general project management activities. Any delays to the project schedule shall be in writing to the City of Fort Worth for review and approval. The ENGINEER shall attend the project kickoff meeting with a proposed schedule for task sequence and completion. The ENGINEER's Project Manager shall schedule and lead all project meetings. Meeting notes shall be submitted to the City of Fort Worth's Project Manager within five working days after each meeting. The ENGINEER shall attend one public meeting to present what possible mitigation alternatives are being explored. The ENGINEER will provide to the City project information regarding proposed mitigation alternatives (if applicable) for public outreach. The ENGINEER will fully document all relevant hardware, software, file structures, and data formats used during the project. The details and structure to be followed are included in EXHIBIT A-1. The draft and final report format to be followed is included in EXHIBIT A-2. Other than intermittent meetings, all of the individual Task deliverables shall be submitted with the draft and final report at the conclusion of the study. The ATTACHMENT "A" Page 2 of 18 ENGINEER shall update a Project Certification and Decision Log to be submitted at the completion of the study. Task 1 Deliverables: • Documentation o Summary of Tasks o Project Schedule o Support Data — Relevant meeting notes and email correspondence, project status updates, and action items for ENGINEER, sub -consultants, and the City of Fort Worth. o Completed Project Certification and Decision Log upon completion of the study. 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. 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 ATTACHMENT "A" Page 3 of 18 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 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 ATTACHMENT "A" Page 4 of 18 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, Basting, 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 anticipated revised areas. The ENGINEER shall meet with the City's Project Manager and discuss which buildings and homes will be surveyed prior to a final scope of work. Finished floor elevations shall be a separate budget item from the field surveys. ATTACHMENT "A" Page 5 of 18 Task 2 Deliverables: • Documentation o Data Collection — Summary of Data Collection efforts and methodology including a list of data collected and sources and locations of reported flooding "hot spots" within the immediate study area. o Field Reconnaissance — Summary of Field Reconnaissance efforts including labeled digital photos and locations of special physical characteristics relevant to modeling and number and locations of crossings. o Stream Condition Assessment Summary o Field Surveys —Summary of field survey efforts including primary control points and locations, elevation reference marks, and locations of surveyed roadway crossings and open sections. o Finished Floor Elevations — Summary of finished floor elevation survey efforts including homes and structures surveyed, finished floor elevations, and lowest adjacent grade. • Digital Data o Data Collection — Data collected from the City and other sources for the study. o Field Reconnaissance — Labeled digital photos and locations of areas of concern. o Stream Conons Assessment —Labeled digital photos and locations of areas of concern and a GIS geodatabase of identified areas of concern. o Field Surveys ■ Text Files: Survey text files in ASCII format of primary control points, secondary control points, elevation reference marks, surveyed hydraulic structures and stream cross -sections. ■ Field Notes: Field notes in PDF format of surveyed hydraulic 0 structures and stream cross -sections. ■ Photos: Labeled digital photos of surveyed hydraulic structures and stream cross -sections. ■ GIS Files: Shapefiles of survey data of primary control points, elevation reference marks, and hydraulic structures and stream cross -sections. ■ Work Maps: Work maps depicting survey data and locations.

ATTACHMENT "A" Page 6 of 18 o ENGINEER will provide all the finished floor survey data including control, finished floor elevations lowest adjacent grade elevations and locations, 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 A 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 II 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. 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 - ATTACHMENT Page 7 of 18 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. 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 ATTACHMENT "A" Page 8 of 18 f 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.

Routing ATTACHMENT "A" Page 9 of 18 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.

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.

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 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. ATTACHMENT "A" Page 12 of 18 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 A the channel segment (Figure 1). Figure 1.

When necessary, prepare a drainage area map of 1" = 200' scale from available contour maps. b. Delineate sub -watersheds as necessary to analyze existing drainage patterns within the study area, as well as to identify and define proposed improvements. c. Obtain hydrologic parameters for each subwatershed including precipitation data, time of concentration, and land use category. d. Create a fully developed hydrologic condition land use map based on aerial photography and the City's land use/zoning maps. e. For applicable projects, execute models to obtain, 10-, 50-, 100- and 500 year return event discharges for use in LOMR submittals to FEMA. PART C -Hydraulic Analysis This scope includes the tasks necessary to size drainage facilities based on fully developed watershed discharges, consistent with criteria in the City of Fort Worth Storm Water Management Design Manual, March 2006 edition. 1. Existing Conditions Analysis a. Perform initial hydraulic calculations based on site visits, previous documentation and information OWNER has obtained from residents to confirm location of existing drainage concerns and operation of existing storm drainage facilities, if any. 2. Recommended Improvements a. Develop a hydraulic model of closed system improvements for the study area. The City's two -foot topographic data will be used to generate grades for the system. The proposed improvements will include sizing and locating inlets, leads, laterals and storm sewer mains to carry design discharges to desired outfall locations. b. Up to two (2) improvement options will be sized based on coordination with City Staff. Conceptual cost opinions will be generated for each option to assist in selection of improvement option. One improvement option will be selected for final modeling. Recommended improvements may include water quality considerations to limit sediment transport through proposed improvements. c. Provide CITY with results of analysis in both digital and hard copy format. Up to three (3) concept and preliminary revisions sets will be prepared for OWNER review and comment in preparation of final exhibits, report and documents. Opinions of Probable Construction Cost will be provided for the selected recommended improvement option. PART D —Project Development This scope includes coordination and communication procedures to be implemented between OWNER and ENGINEER in completion of this project. 1. Project Coordination On . Conduct up to four (4) project status meetings with CITY. Meeting shall be used to update CITY as to status of project and to determine CITY preference in recommended improvement option. b. Conduct up to two (2) site visits to project site with CITY, upon CITY request. c. In coordination with CITY, conduct one (1) public involvement meeting to supply project information, goals and schedule to the surrounding residential community. ENGINEER will prepare up to two (2) graphical exhibits for use in public presentations. d.

CODE: C TYPE: NON- PUBLIC NO CONSENT HEARING: SUBJECT: Authorize an Agreement with James DeOtte Engineering, Inc., in the Amount of $243,053.00 for Greenfield Acres Drainage Master Plan RECOMMENDATION: It is recommended that the City Council authorize the City Manager to execute an agreement with - James DeOtte Engineering, Inc., in the amount of $243,053.00 for the Greenfield Acres Drainage Master Plan. DISCUSSION: In order to address stream flooding and neighborhood flooding, detailed drainage studies are required to determine runoff rates and flow depth, identify flooding areas and deficiencies in current drainage facilities, to verify and correct Federal Emergency Management Agency (FEMA) Flood Insurance Rate Maps, to develop a master drainage plan consisting of proposed storm drain and channel improvements, detention and other measures to reduce building and street flooding. In November 2007, a Request for Qualifications (RFQ) was advertised for neighborhood drainage studies. Twenty-three statements of qualifications were received and James DeOtte Engineering, Inc., was selected to prepare the Greenfield Acres Drainage Master Plan, Storm Water Study SWS- 005. The scope of work will include: a detailed study of an unnamed stream in this neighborhood with a FEMA floodplain; preparing documents to obtain a FEMA Letter of Map Revision; identification of erosion repair and other minor projects which may be needed; and, developing both a watershed master plan for future channel and culvert improvements to further reduce stream flooding, as well as a drainage master plan of the surrounding neighborhood in order to identify future capital improvements and to estimate project costs. James DeOtte Engineering, Inc., proposes to perform this study for a lump -sum fee of $243,053.00. City staff considers this fee to be fair and reasonable for the scope of services proposed, based on the length of stream and size of the study area. The Storm Water Utility Operating Fund will be used to fund this study. James DeOtte Engineering, Inc., is in compliance with the City's M/V1/BE Ordinance by committing to 18 percent M/WBE participation. The City's goal for this project is 18 percent. This project is located in COUNCIL DISTRICT 7. 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.
