While this work is ongoing, other priority areas for stormwater management improvement will be addressed by the CITY. This amendment addresses one of those areas, the Pinehurst Stormwater Drainage Project (Project). The Project is partially funded by the 2002/2003 Legislature General Appropriation Act funds from the Florida Department of Environmental Projection (FDEP) through Special Appropriation 1769. These funds are administered through the South Florida Water Management District (SFWMD) and dispersed and managed at the local level. The Pinehurst project area is an approximately 165 acre developed residential and industrial area located in the CITY. The area drains to the Miami River (via Wagner Creek) and ultimately to Biscayne Bay, and has been named a priority area by the Biscayne Bay Surface Water Improvement and Management (SWIM) plan as part of the Miami River basin. It is bounded by NW 28th Street to the north, NW 20th Street to the south, NW 17th Avenue to the west and NW 12t Avenue to the east. The Pinehurst project area currently has a number of isolated drainage systems which discharge to the Wagner Creek box culvert and to the Braddock Storm Sewer System, which also outfalls to the open channel portion of Wagner Creek located on NW 14h Avenue south of NW 18`a Street. These systems are comprised of solid pipe, catch basins, manholes, and french drains. The area experiences flooding in several different locations, has a solids accumulation problem at storm water system inlets associated with the flooding, and has been documented to contribute contaminants loading to the Miami River via Wagner Creek. The CITY authorized PBS&J to perform preliminary engineering for evaluation of modifications to the existing stormwater system. Based on that report, the CITY intends to pursue improvements to the system. 2.0 Objective The City has determined that the Pinehurst area is in need of storm drainage system improvements. The objective for this project is to meet the Miami -Dade Department of Environmental Protection (DERM) water quality criteria and to alleviate the flooding experienced during and after storm events. Completion of this project will improve the overall stormwater management system in the City and will help minimize flooding during peak rainfall events. Amendment 01 to Agreement No. C.13164 Page 1 of 4 3.0 Scope or Work The project consists of the design, permitting and construction of an estimated 6,700 linear feet of french drain, 9 pollution control structures, 7 water control structures, 27 manholes, 12 catch basins, 250 linear feet of 15" solid corrugated metal pipe and 360 linear feet of 24" solid corrugated metal pipe (CMP). These components will be interconnected to the existing systems to provide additional treatment and storage capacity, where feasible, in the Pinehurst project area. 4.0 Work Breakdown Structure Project Management The CITY shall be responsible for the satisfactory completion of this project and may retain a consultant to provide the professional services needed to complete the stormwater and roadway plans and to assist the CITY during construction. The CITY, or its designated consultant, as applicable, 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.
