Dear Mr. Eubanks: Lockwood, Andrews, & Newnam, Inc. (LAN) has included herein for your consideration our revised proposal to provide the City of Fort Worth professional engineering services. The services provided include converting the SWMM5 models prepared for the City in the planning phase of this project into InfoWorks SD models and modeling the existing closed system as provided by City GIS data in the ECBD basin with the subject model being converted. The proposed services include those outlined in "Attachment A" and as shown in Figure 1, Figure 2 and Exhibit A-1. We propose to provide professional services for a not to exceed lump sum amount of$284,400.00. Twelve (12) months are estimated for design completion inclusive of review. We have included City of Fort Worth standards Attachment A-Scope of Work,Attachment B—Compensation & Payment Schedule with Exhibits 13- 1, B-2, B-3, B-3A and Amendment No. 1. LAN will demonstrate a good faith effort to include at least 6%M/WBE participation for this contract amendment. We appreciate the opportunity to provide this revised proposal and look forward to continuing our relationship. Should you have any questions or comments, please do not hesitate to contact me.

The ECBD in the City of Fort Worth (City) watershed planning study included hydraulic modeling using the EPA-SWMM 5 software. The City has requested that the model be upgraded to InfoWorks SD software due to its ability to model complex drainage networks and to include previously unmodeled segments from the watershed. Lockwood, Andrews, and Newnam Inc. (LAN) estimates the conversion of the SWMM 5 models for both existing and proposed conditions involve the following steps. Professional Services 1. InfoWorks Modeling a. Convert existing SWMM 5 model to InfoWorks using the previously created geodatabase for the ECBD study. i. Verification of runoff parameters ii. Verification of storm drainage hydraulics iii. Adaptations/modifications for inlet representations iv. Verification of overland flow elements v. Update storage areas vi. Transfer rainfall values for historical and design events b. Compare the results of the existing SWMM 5 model with the InfoWorks model. i. Investigate modeling discrepancies ii. Delineation of inundation limits c. Model proposed alternatives in InfoWorks. i. Determine the overall applicability of results. d. Develop new alternatives as needed. e. Provide quality control/assurance. f. Field verify by observation existing model conditions through recent as-built plan data as construction activity may have occurred in the ECBD over the past three (3) years. g. Preliminary opinion of probable construction costs. 2. Coordination and Deliverables a. Meet with the City to discuss any major issues with the existing model conversion. b. Meet with the City to discuss the results and revised cost opinions from the InfoWorks modeling of the proposed alternatives. c. Prepare a supplemental notebook report summarizing the findings, recomme.dations, alternatives and models. d. Each report submittal shall include three (3) copies. Final report shall include electronic files and data. ATTACHMENT "A" Page 1 of 2 3. Standardize final report and findings to City provided standard; including participation in three (3) meetings organized by the city to collaborate with other consultants and city staff and to assist in creating/providing standard improvement data sheet packets. 4. Add additional laterals and inlets to the InfoWorks model that were previously not modeled. (Reference Figure 1: SBA Basin, Figure 2: SBB Basin and Exhibit A-1 "Additional Modeling") a. Use same methodologies as previous model (SCS Runoff Method, normal depth for tailwater). b. Execute the calibrated model to develop flood flows, storm drain capacities, ponding depths, and overland flow elevations for the 10-year, 25-year, 50-year and 100-year events. c. Map all identified flood-prone areas and, to the extent practical, identify which or how many structures may be subject to inundation. d. Deliverables shall include electronic versions of the models, as well as summary presentation exhibits to be determined based on the modeling results. Also included will be a report summarizing study methodology and results. 5. Improvement Plan a. After existing conditions are complete, analyze previously proposed alternatives to see if they are still viable. Alternative flooding solutions shall be designed for a 100-year level of protection, as well as for lower levels of protection as may be appropriate based on modeled conditions. b. Prepare proposed conditions computer models for each alternative solution, including any interim and/or multi-phased solutions. c. Develop a cost-effective analysis for each alternative based on estimates of approximate flood damage benefits and probable project (design and construction) costs, with consideration given to easement and right-of-way acquisition and utility relocation requirements. d. Deliverables shall include a report summarizing methodology for developing of the improvement plan, together with a summary of alternatives investigated and recommended improvement plan. Improvement plan shall include proposed prioritization, phasing and a summary of project costs. Electronic deliverables shall irclude final report, alternatives models, and GIS mapping of recommended improvement plan showing preliminary alignment and sizing. Additional Services 1. Field survey data collection. City Responsibilities 1, Provide GIS data for additional modeling with sufficient detail and additional surveying. Schedule The project shall be completed within twelve (12) months after receiving the executed amendment and the notice to proceed from the City.

CODE: C TYPE: CONSENT PUBLIC NO HEARING: SUBJECT: Authorize the Execution of Amendment No. 1 to the City Secretary Contract No. 33118, an Agreement with Lockwood, Andrews & Newnam, Inc., for the East Central Business District Watershed Planning Study in the Amount of$284,400.00 (COUNCIL DISTRICTS 8 and 9) RECOMMENDATION: It is recommended that the City Council authorize the City Manager to execute Amendment No. 1 to the City Secretary Contract No. 33118, an agreement with Lockwood, Andrews & Newnam, Inc., for the East Central Business District Watershed Planning Study in the amount of$284,400.00 for a total contract price of$516,200.00. DISCUSSION: A Request for Qualifications (RFQ) for Watershed Planning Studies was issued by the City in March 2004. Seventeen engineering consultants submitted statements of qualifications, and Lockwood, Andrews & Newnam, Inc., was selected to perform the East Central Business District Watershed Planning Study. Due to budget constraints at the time, the initial study included detailed mapping and inspection, as well as hydraulic modeling, along only the major trunk lines within this storm drain system. A detailed improvement plan for these trunk lines documented both drainage capacity deficiencies and structural deficiencies along the storm drain trunk lines in the existing drainage system. Staff has determined that additional study is required, including conversion of the hydraulic model to a more stable modeling program, developing a hydraulic model for sections of storm drain not previously studied, and expansion of the improvement plan to address deficiencies throughout the entire storm drain system. Lockwood, Andrews & Newnam, Inc., proposes to perform the study for a lump sum fee of $284,400.00. City staff considers this fee to be fair and reasonable for the scope of services proposed. The Stormwater Utility Fund will be used for work under this amendment. Lockwood, Andrews & Newnam, Inc., is in compliance with the City's M/WBE Ordinance by committing to an additional six percent M/WBE participation on Amendment No. 1, This project is located in COUNCIL DISTRICTS 8 and 9. FISCAL INFORMATION/CERTIFICATION: The Financial Management Services Director certifies that funds are available in the current operating budget, as appropriated, of the Stormwater Utility Fund.
