The net result of this amendment will be a no change in total compensation and only a change in the scope of work to de accomplished. The amended tasks are described below: A. ADDED SCOPE-STORM DRAINAGE SYSTEM ANALYSIS 1. Stormwater Master Plan(Increased scope to cover the Trinity Uptown area) i. Project Management and Meetings a. Prepare for and conduct up to six(6)meetings with TRVA partners to coordinate and discuss Trinity Uptown Stormwater Master Plan. ii. Hydrology a. Delineate drainage basins and perform hydrologic computations to the inlet — level for proposed storm drainage systems in the Trinity Uptown identified as: Arthur System (White Settlement Road); Police Academy System (Henderson Street); Grand Avenue System (Main Street northwest); Calhoun North System (Main Street northeast); Calhoun South System(Main Street south), and outfalls to the canals. b. Coordinate with and provide input to Civil Engineer providing Mass Grading Plan for Trinity River Vision Uptown Area. Drainage delineation for proposed conditions will be based on the Mass Grading Plan. At the time of this contract, the Civil Engineer providing these services has not been identified. c. Incorporate consideration of proposed bypass channel and gate operation in determination of hydrographs to be utilized for hydraulic computations. d. Hydrologic computations will be performed using the current USACE HEC-HMS models and the Wallingford Infoworks software, 2D methodology, as utilized in determining existing conditions, e. Runoff hydrographs will be computed for return events including the 2, 5, 10, 25, 50,and 100-year probability storms using CoFW frequency precipitation data. f. Fully-developed conditions discharges will be computed by incorporating future development information as provided by the City of Fort Worth and TRVA partners. Up to three different land use scenarios will be utilized to determine expected discharges. iii. Hydraulics a. Perform hydraulic computation on the systems described herein. b. Generate color-coded maps to demonstrate the retum-event capacity of each system analyzed. c. Identify and quantify system overflow locations and depths for 25- and 100-year return event storms. d. Determine proposed sizes and preliminary routes for storm drainage systems within the Trinity Uptown area. These systems will meet the CoFW criteria in the Storm Water Management Design Manual, March 2006,or latest revision. e. Evaluate up to three different proposed alignment options iv. Water Quality Management a. Coordinate with APAI to determine storm water quality impacts of proposed alignments. b. Recommend storm drain alignment alternatives that minimize water quality impacts. v. Excluded Services: The following tasks are specifically excluded from this Scope of Services. It is anticipated that these services shall be perforated in Future Phases of this Project. a. Water Quality Management other than that described above, Capital Improvement Planning or Phasing or financial models for Capital Improvement Planning or Phasing,or Stormwater Design Criteria for development in the Trinity Uptown area.Water Quality Management research,development,consultation or coordination b. Consultation with any member of the development community for Design Guidance related to redevelopment or future development of the Central City area. c. Capital Improvements Planning or Modeling for the Central City d. Design Guidance recommendations for future development or redevelopment of the Central City area. vi. Deliverables a. Prepare a brief Summary of Findings and Design Considerations for each alternative evaluated. Up to five(5)copies of the report will be submitted. b. Determine a conceptual Opinion of Probable Cost for each alternative. c. Prepare graphic, color-coded exhibits showing proposed alignments. Exhibits will be distributed in both hard copy and digital format. d. Submit all digital hydrologic and hydraulic analysis models used in the development of the recommendations. B. REDUCED SCOPE -ENVIRONMENTAL STUDIES The original scope of services covered environmental studies of proposed utility (franchise and stormwater) relocations for the Central City project. This amendment will reduce the current scope, based on a monetary budget of $33,072 rather than studying the entire limits of the utility (stormwater and franchise) relocations. It is the intent of this amendment to include the remainder of the environmental work for the utility relocations (stormwater and franchise) in the next phase (Phase 2)of this TRV project.
