SUMMARY The Marlins Ballpark Project includes a stadium that can accommodate 37,000 spectators, open spaces to include a Plaza, four related parking garages and six surface lots, 61,678 Square Feet of retail space and 96 residential dwelling units proposed to be constructed on the site of the demolished Orange Bowl Stadium. The project will be constructed in the area bounded by N.W. 13'h Avenue and N.W. 17`x' Avenue, and N.W. 3'a Street and N.W. 7`j' Street in the City of Miami. Improvements planned for this project include: New pavement, curb and gutter, sidewalks and drainage structures for perimeter streets. • New water distribution mains and fire hydrants. • Sanitary sewer line. + New storm drainage and management system, catch basins, pipes, pump station and outfall reconstruction. • Reestablishment of N.W. 4`I' Street and N.W. 6th Street as Private Drives, between N.W. 14'h Avenue and N.W. 16'" Avenue. The area is being re -platted to vacate conflicting street right of ways.

WATER MAINS At full capacity (37,000 Spectators), retail and residential unit's domestic flow demand will be an average of about 133,284 gallons per day. Based on peak demand factor of 2.5, the peak demand is estimated to be about 233 gallons per minute, See Table I. New water mains will be constricted to upgrade the area's system to current code requirements for main sizes and fire flow capacity. Additional fire hydrants will be installed per current fire department regulations.

SANITARY SEWERAGE At full capacity, the ballpark (37,000 Spectators), retail and residential units will generate an average sewage flow of about 133,284 gallons per day, See Table 1. Based on the mechanical consultant recorded demand data from other ballparks with similar seat capacity, the peak demand for the Marlins Ballpark is estimated to be about 1,100 gallons per minute. New Sanitary lines will be constructed to upgrade the area's system to current code requirements as per MDWASD regulations to meet the sewer flow capacity. MDW&SD treatment plant has adequate capacity to receive, handle and treat the flow fi-om the new ballpark, retail and residential units. New Sanitary lines to be installed: Street. Limits Size *N.W.

G`h Street 12 inch * Indicates new construction within a private drive being designated as utility and access easements rather than dedicated as public roads. V. STORM SEWER DRAINAGE The site is located in the Orange Bowl drainage basin and is currently drained by a system of on- site exfiltration trenches and out -fall pipes in the streets. These pipes convey stormwater to the Orange Bowl drainage pump station located at N.W. 7"' Street and N.W. 17't' Place, where the station pumps into the Lawrence Park Canal which flows to the Miami Canal. The existing drainage system is not designed for and does not meet DERM's design criteria of handling the stormwater from a 5 year — 24 hour storm. We are proposing to install a new on-site and off-site drainage system, with the objective of meeting the following listed goals and criteria: • Potential to capture and store some quantity of storm water for irrigation and other uses at the ballpark. • Provide pretreatment of stormwater to enhance the quality of the discharged water per DERM requirements. ■ Meet the design storm criteria established by DERM for the stormwater system. The following drainage improvements are being considered as the design progresses: ■ Exfiltration trenches to capture and infiltrate the first flush of run-off to improve the water quality of the remainder discharge. ■ Storm drainage wells to provide additional retention and disposal capacity. ■ New catch basins and 48" pipes in the adjacent streets that are to be improved as directed by the City of Miami, Public Works department. ■ Re -line or otherwise improve the existing drainage lines from the ballpark site to the pump station. ■ Install new drainage pumps in the existing pump station, including new controls, weirs and discharge pipes to the Lawrence Park canal. • Install structural improvements, such as roof upgrades, etc. for the existing pump station building. 20087024 Site Utilities A 02 05 2009.doe (3) r - � VT_ CTAS Gas lines, owned by TECO Peoples Gas Co., are available in the adjacent streets, and have adequate capacity to serve the new ballpark's needs. VII. ELECTRIC New electric service will likely be provided by the Florida Power & Light Company from the existing sub -station, Latin Quarter substation, located at 500 S.W. 171" Avenue. Final details of the new service are being developed, but have not been established at this time. This will include an extension along N.W. 16`h Avenue or N.W. 171h Avenue to said Latin Quarter substation. VIII. SOLID WASTE Based on frill occupancy, it is estimated the ballpark, retail and residential units can generate about 9.64 tons of solid waste per day. To reduce solid waste to the landfill, a significant amount of the waste material will be collected and stored for recycling. The waste material not suitable for recycling will be collected daily by a private commercial hauler. The project will plata for occupant recycling with easy -to -locate and convenient collection areas and storage of recyclables for pick-up by the recycler. The recycling program will be integrated to include concessions, office areas, suite and club level, operations and maintenance areas. Designated storage for recyclable materials will be allocated in the buildings with easy access to the dock. Can crushers, balers or other waste management technologies will further enhance the recycling program. IX. TELECOMMUNICATIONS Telecom lines are located in the adjacent streets and are available for the project. X. TABLE I -- Water Sewer and Solid Waste Impacts. — See Pae 5. XI.
