SWS-036 AMENDMENTS TO THE STANDARD SCOPE OF SERVICES, ATTACHMENT "A" Project Summary a. Purpose of Study Freese and Nichols (ENGINEER) is pleased to submit this proposal for additional flood study per City of Fort Worth (CITY) request for Edgecliff Branch and its tributary French Lake Creek (See Figure 1). The additional study was requested for the Tributary SC-7 and Edgecliff Branch Open Channel Study (Study No. SWS-036) currently in progress. Additional tasks include stream condition assessment, field survey, hydraulic study, watershed flood hazard assessment, proposed flood mitigation alternatives analysis, report preparation and Letter of Map Revision preparation and submittal assistance for approximately 1.3 stream miles of Edgecliff Branch and approximately 1.2 stream miles of French Lake Creek. b. Pertinent Data The additional reach of Edgecliff Branch to be studied for this Open Channel Study is from the Woodway Drive crossing (downstream) to South Hulen Street (upstream). The study will also include the French Lake Creek tributary to Edgecliff Branch between Willow Way Road (downstream) to Trail Lake Drive (upstream). See Figure 1 — Additional Edgecliff Branch and French Lake Creek Study Areas Map for study stream limits. Task 2: Data Search, Collection, Field Reconnaissance, Stream Condition Assessment, and Surveys c. Stream Condition Assessment ENGINEER will perform a stream geomorphology evaluation for Edgecliff Branch and its tributary French Lake Creek (approximately 2.5 miles) to identify existing and potential erosion areas and to propose channel stabilization alternatives. Task 1 — Site Visit A stream assessment will be conducted to evaluate the current condition of the creek. This will be achieved by conducting a geomorphic assessment of the channel at 200 foot intervals. During the stream assessment the sediment source and discharge areas will be located as well as all hard points within the creek. The field survey will include a visual summary of channel conditions by river reach (photographs of the left and right bed and bank and upstream and downstream). The bed and bank material will be EXHIBIT"A-3" Page 1 of 3 sampled for sieve analysis. The geology of the reach will be noted considering the rock type, degree of weathering, and thickness of the alluvial soils. Bank stability and degree of erosion will be noted, as well as the distance to and type of structure that may be impacted. Channel dimensions will be measured with a survey rod and laser to determine bank geometry. All locations will be marked with GPS receiver employing sub-meter accuracy. Preparation for the field is also included in this task. Task 2 — Preliminary Evaluation Preparation for the channel stability assessment report will include desk top analysis of the soils, landuse, channel and landscape, and geology. A field assessment overview will include the bed and bank material evaluation and calculation, equilibrium slope calculation, reach survey channel geometry calculations and reach structure and distance from channel. For stream assessment calculations, the design or dominant flows from the models will be obtained from the modeling component of this project. Evaluation will include a summary of the study area, channel stability assessment methodology, and field assessment methodology. There will be a field assessment overview describing the geology and soils, bed material evaluation, equilibrium slope, and meander migration potential. The field survey results will include the reach survey data, the reach survey channel erosion, the reach survey channel geometry, and possible reach survey structure and distance from channel. Deliverables will also include labeled digital photos and locations of special physical characteristics that may be relevant to modeling and locations of observed areas of concern in addition to comments on the present conditions. d. Field Surveys For the additional Edgecliff Branch and French Lake Creek Open Channel study there are approximately five (5) open channel cross-sections, approximately six (6) hydraulic structures, and approximately five (5) residential or commercial structures finished floor elevations to be surveyed. The anticipated field survey locations are shown on Figure 1 — Additional Edgecliff Branch and French Lake Creek Study Areas Map. The anticipated hydraulic structures to be surveyed are listed below. No. Stream Crossing Name 1 Edgecliff Branch Welch Avenue 2 Edgecliff Branch Kingswood Drive 3 Edgecliff Branch Pedestrian Bridge 4 French Lake Creek Willow Way 5 French Lake Creek Wind Chime Drive 6 French Lake Creek South Hulen Street Task 4: Development of Hydraulic Models and Floodplain Maps a.

DISCUSSION: A flood study of the SC-7 and Edgecliff Branch tributaries of Sycamore Creek is currently contracted with Freese and Nichols, Inc. In the course of the study, it was determined that the study area needs to be extended to include French Lake and the tributaries between Woodway Drive and Trail Lake Drive. This on-going study will develop mitigation alternatives to protect homes from flooding, evaluate the engineered channel from Trail Lake Drive to South Hulen Street, and revise mapped floodplain as needed. The SC-7 and Edgecliff Branch tributary open channel study was approved by the City Council on July 12, 2011(M&C C-24995).
