(FDEP) through Special Appropriation 2064A. These funds are administered through the South :Florida Water Management District (District) and dispersed and managed at the local level. The City is located within the east -central portion of Miami -Dade County and is roughly bounded by unincorporated and incorporated portions of central and southeastern Miami -Dade County to the North, West and South, including the Village of El Portal, Miami International Airport and the City of Coral Gables, and Biscayne Bay to the south and east. Portions of the City fall within the various drainage basins associated with east -central Miami -Dade County, namely, the C-3, C-4, C-5, C-6 and C-7 Basins. The proposed project under Section 3.0 herein, falls within a portion of the C-3 Basin, and is an area bounded by SW 22nd Street to the north, US Highway 1 to the South, SW 37th Avenue to the west and SW 32nd Avenue to the east. The main conveyance in the C-3 Basin is the C-3 Canal, which begins as an open channel connection at the C-4 Canal to the northwest of the project area, and generally flows southeast to Biscayne Bay. The C-3 Canal was originally designed to provide flood protection for a 25 year storm. However, urban development in the basin has most likely led to a decrease in the conveyance's flood protection capacity. There low lying streets with low floor elevations in the area, and significant storm activity causes localized flooding throughout the basin. The City has developed a multi -phased Stormwater Master Plan (Plan), which was adopted by the City Council, and is currently being implemented. The City recognized the need to address its storrnwater challenges through the implementation of this Plan. In addition, the City is an active member of the Miami - Dade County Local Mitigation Strategy (LMS). The existing drainage system of the project area has historically consisted primarily of roadside inlets connected to outfalls located throughout the City. When this area was originally developed, the fllood. criteria at that time was insufficient to meet the changes in hydrology brought about by development over the following years. In some cases, the outfall structures are no longer discharging, or are undersized for the volume they are expected to handle. The system provides poor levels of flood protection and provides little, if any, treatment of storm runoff. There are structures in disrepair and in need of immediate replacement. This undesirable scenario potentially lends itself to short and long term flooding conditions within the City, and as a consequence of these deficient conditions, the area experiences frequent flooding. 2.0 OBJECTIVE The objective of the Project is to improve the City's stormwater capabilities by providing a posi.tive drainage system to surface waterways in the geographic area. The Project will provide for improved flood protection while maximizing water quality treatment of storm runoff prior to discharge through typical Page 1, Exhibit "A", Statement of Work, OT050648 treatment methods and best cost effective available technologies. All improvements within the Project are described in Section 3.0 of this Statement of Work. 3.0 SCOPE OF WORK This project involves the design and construction of storm sewer improvements to include exfiltration trenches, cross drains, catch basins, manholes, a storm sewer force main, an emergency pump -out wet well and surface restoration of all rights -of -way. This project area is bounded by SW 22 Street, US-1, SW 37 Avenue and SW 32 Avenue. Specifically, the Scope of Work shall entail the following: • Engineering design and development of specifications specific to each location within the project area. • Permitting. • Development of bid documents and conductance of bidding. • Construction of drainage structures and appurtenances, treatment features, force main, piping and related features to facilitate conveyance from surface areas to receiving bodies. • Construction of right-of-way restoration. The City shall be responsible for the satisfactory completion of all work under this Statement of Work. This Statement of Work will focus on activities that include the following tasks: Task 1: Task 2: Task 3: Task 4: Engineering Design and Permitting Preparation of Bid Documents and Specifications Construction, Construction Monitoring/Monthly Reports Construction Certification The Project will meet the regulatory requirements of all government agencies with permitting jurisdiction. 4.0 WORK BREAKDOWN STRUCTURE At the end of each task, the City shall deliver Three (3) copies of the task deliverables to the District. The District shall distribute the copies to the FDEP for its information and use. The District shall distribute the project summary including estimated cost to the designated coordinator for the Local Mitigation Strategies Group for its information and use. Project Management The City is responsible for project management, budget management and quality control. The City is responsible for reviewing and approving deliverables from the consultant to ensure that the project objectives are met. Task 1: Engineering Design and Permitting • Prepare and submit to the District 100% engineering plans Page 2, Exhibit "A", Statement of Work, OT0506448 • Prepare and submit to the District construction costs estimates for the proposed work. • Submit to the District proof of application for applicable permits. Deliverables: Summary Report including submittal of surveys, 100% engineering design plans, cost estimates and other information described in this task number 1. Task 2: Preparation of Bid Documents and Specifications • Prepare and submit to the District Bid Documents. • Prepare and submit to the District specifications. • Advertise Bid and conduct pre -bid meeting. • Receive and open bids. • Prepare bid tabulations and evaluate for successful bidder. • Award Bid. • Prepare and submit to the District bid and contract award documents. Deliverables: Summary Report of bid documents and specifications including submittal of the information described in this task number 2. Task 3: Construction, Construction Monitoring/Quarterly Reports • Submit project summary with final engineer's cost estimate. • Monitor the construction of the project and submit progress reports and construction invoices. • Construct improvements as identified in I00% design plans, specifications and applicable permits. • Prepare and submit to District construction schedule(s), quarterly construction progress reports, quarterly pay requests, and quarterly updated construction project schedules. Deliverables: Submit to District work documents and information described in this task 3. Task 4: Construction Certification • Provide final certification and as -built drawings upon completion of construction. Deliverables: Provide to the District final certification and as -built drawings upon completion of construction. Page 3, Exhibit "A", Statement of Work, OT050648
