A meeting with FP&L representative is recommended to determine the feasibility of relocation ;' modifying the existing FP&L facilities. Existing facilities may or may not be sized to service proposed project. Owner, MEP Engineers shall be required to contact FP&L directly to coordinate loads and distribution systems. Am D.A. ENLINEER NG, 1N . Wagner Square Site Utility Study TELEPHONE Telephone service is provided by Bellsouth. / AT&T which has overhead and underground lines serving the area. Existing facilities may or may not be sized to service proposed project. Owner, Engineers shall require to contact Bellsouth 1` _'AT&T directly to coordinate loads and distribution systems. WATER DISTRIBUTION The Miami -Dade County Water and Sewer Department (WASD) are current ' responsible for providing water service to the project area. There are existing water mains in the project area. The locations and sizes of these water mains are as follows: a 12" WM along NW 18th Street (north side of property), an 8" WM along NW 15`I' Avenue (west side of property), and a 6" W.M. along NW 171 Street (south side of property). Refer to .Attachment B. WASD recommends that the point of connection be the 12' WM along NW 18th Street. WATER MAINS Location Between NW 18TH Street NW 1 5th Avenue NW 17th Street NW 14 Avenue and NW 15 Avenue (North side of the Project) NW 17th Street and NW 18th Street (West side of the Project) NW 14th Avenue and NW 15`h Avenue (South side of the Project) Water Main (s) 12" D.I.P. 8" D.I.P. 6" D.I.P. As per WASD, if two or more fire hydrants are to be connected to a public water main extension within the property, then the water system shall be looped with two points of connections. Additionally, separate connections for fire lines and fire hydrants shall be required. The Buildings as proposed shall require domestic and fire service connections and can be tapped from the public trains. The City of Miami Fire Department will also require that fire hydrants be located no more than 300 feet from the proposed buildings, and that there be no more than 300 feet between hydrants fronting the property (measured along the watermain). For buildings requiring fire sprinklers, a fire hydrant must be located no more than 100 feet from each buildin.g's `;tire department connection"(siamese). According to the code, new hydrants will not be allowed on watermains less than 8" in diameter. Any proposed buildings exceeding 12,000 SF of floor space will require that fire sprinklers be installed, Additionally, no on -site fire, domestic water, or irrigation wells are planned for the project at this time. A 3.A. ENGINEERING, INC.

There are existing gravity sewer mains in the project area. The locations and sizes of these gravity pipes are as follows: An 8" gravity sewer main along a public alley and a 10" gravity sewer main along NW 1.7th Street (south side of property), and a 1.2" and a 42"gravity sewer mains along NW 151h Avenue (west side of property). Location SEWER MAINS Between Water Main (s) Public Alley NW 17t" Street NW 15th Avenue East of NW 15th Avenue (South side of the Project) West of NW 14th Avenue (South side of the Project) NW 17th Street and NW 18th Street (West side of the Project) 8" Gravity 10" Gravity 12" Gravity & 42" Gravity Refer to Attachment C. The point of connection is subject to an engineering analysis by WASD. Owner must apply for the sewer allocation from Miami -Dade County DERM to see if adequate capacity exists in the existing sewage collection an.d transmission systems, including regional pump stations. It is important to note that improvements to the existing sewage pump stations receiving flow from this project may be required based upon the sewage flows discharged by this project. The total sewage discharge is approximately 81,638 gallons per day. DRAINAGE The total project area is approximately 147,448 square feet (3.38 acres) [equals net lot area The existing site is a vacant lot with no on -site drainage facilities. Existing storm drainage systems within the public rights -of -way surround the project site and are owned and operated by D.A. ENGINEERING, Item Wagner Square Site Utility Study t c City of Miami. Several s.xis2.. stor, ins were observed along the abutting streets. However, water quality requirements will have to be met on site as required by 3)FRM. No drainage connections € ill. be proposed to any of the C ity's existing storm dtain.a e systems. For the purposes of a conservative stormwater management engineering analysis, the entire site shall be considered to be impervious. Water collected from rooftops, vertical building spaces, pedestrian. areas; and driveways shall be included in the storrnwater• drainage system.. Total Net Lot Area (acres) 3.38 Impervious Area Vertical Building (acres) laces.....acres.................... 3.38 E 1.90 i otal_ Drainage Area .....(acres). 5.28 Runoff from the above mentioned locations shall be collected in catch basins. The catch basins shall be installed with baffles to prevent debris from entering the storm drainage system. The design storm shall be the Miami -Dade County DERM 5 year, 24 hour storm for a period of 90 seconds. The design shall be based on the use of exfiltration trenches around the perimeter of the buildiruz. In the event that additional storm drainage is required or insufficient area for the exfiltration trenches is available, drainage wells may also be utilized. In addition, water collected inside the parking garages shall be collected and discharged into the sanitary sewer system. A sump pump shall be provided as required. SOLID WASTE GENERATION It is anticipated that approximately 13,732 lbs per day of solid waste may be generated by this project. Condominium apartments (104 units x 5 lbs / day) = 520 lbs per day Office/Retail/Restaurant (330,299 s.f. x 4 lbs/ 100 square feet / day) = 13,212 lbs per day Total solid waste = 13,732 lbs per day or 6.87 tons per day. Solid waste shall be placed and stored in standard on -site containers for both refuse and recyclables. These containers shall comply with the applicable City of Miami codes. Additionally, the solid waste shall be transported to Miami -Dade County Solid Waste Disposal facilities via regular pick-up service by the City of Miami Solid Waste Department or private hauling companies.
