Project Location and size: The proposed project consists of a Multi -use Facility to be constructed at an approximately 2.10 acre downtown Miami. The project limits are: to the west South Miami Avenue to the north SE 2nd Street to the east SE 1st Avenue to the south Metromover The property being in Section 37, Township 54 South, Range 41 East, Miami - Dade County, Florida. B. Existing Conditions: The entire site consists of 7 different lots. These lots are vacant In their existing condition and are being used as public parking facilities. 2 • • r`w111•111111r 1111111 �rrr 01) (O.; 1 ir z Since 1989 CIVIL LAND DEVELOPMENT TRAFFIC AND TRANSPORTATION C.

Storm Drainage System CIVIL LAND DEVELOPMENT TRAFFIC AND TRANSPORTATION A. Existing Storm Drainage System: Roadway storm drainage systems presently exist along the streets surrounding the proposed project. These systems are owned and maintained by the City of Miami. The site, in its existing or proposed conditions, does not or will not contribute any significant amount of storm water run-off into the Public Roadway System. No significant improvements to the existing Roadway Drainage System are expected as a result of this project other than some possible inlet modifications associated with the street or sidewalk improvements. B. Proposed On -Site Storm Drainage System: The proposed storm drainage system to serve this project will be designed to fully contain on -site the storm water run-off and to meet the Miami - Dade County Department of Environmental Resources Management (DERM). This will be accomplished by means of deep drainage wells. No off- site run-off will be generated from the site. The total contributing site area and 30% of the building wall area exposed to the rain will be included in the Disposal Well System design calculations. An impervious coefficient of 0.95 will be used for the purpose of this study. Based on information provided by an experienced well drilling company for other projects in the vicinity, an approximate well discharge rate 750 gpm per foot of head can be expected. Storm water from roofs, internal driveways, walkways and parking areas will be conveyed by means of a collection system to sediment tanks sized to meet the detention volume requirements prior to discharging into the Well System. Additional Water Quality pre-treatment and Pollution Retardant Baffles at the catch basins will be provided at areas subject to vehicle traffic. 4 MIIIIrrrrrrMIS aim rrr� wwNIMIww MIN � L � OR j tr ® ® g.0 gi to @j 1 Since 1989 C. Required number of Wells: CIVIL LAND DEVELOPMENT TRAFFIC AND TRAN5PORTATK N The proposed wells will be designed to maintain the site dry during the 5 year-24 hour storm, to keep flooding below the perimeter grades during the 25 year-3 day storm and to keep flooding below the minimum floor elevation during the 100 year- 3 day storm. Based on the attached calculations, a total of three (3) — 24" diameter storm drainage wells are required to provide full on -site retention for this project depending on the actual yields obtained during the well drilling operations. For Well Disposal System calculations refer to attached Exhibit "B". • • 5 • • • MI& 11111011001 1ww1.111ME 4� 1— Since 1989 3. Water Distribution System A. Existing Water System Facilities: CIVIL LAND DEVELOPMENT TRAFFIC AND TRANSPORTATION Miami -Dade Water & Sewer Department (MD-WASD) owns and operates the following domestic water facilities in the vicinity of this project: • An existing 12-inch and an existing 6-inch water main on S. Miami Avenue. Those run along the entire westerly boundary of the property. • An existing 8-inch and an existing 30-inch water main on SE 22" Street. Those run along the entire northerly boundary of the property. • An existing 10-inch water main on SE 1st Avenue that runs along the entire easterly boundary of the property. These existing water mains can be used to provide fire protection domestic and landscape irrigation service for this project. This project will have to be analyzed by the MD-WASD Infill Committee to determine if additional extensions or contributions are required. That will be done at the time of permitting. B. Required Water System Improvements: Based on the records provided by Miami -Dade Water and Sewer Department (MD-WASD) the existing water mains appear to be adequate to support the proposed development. MD-WASD lnfill Committee may require additional system improvements to upgrade the 10" water main on SE 2n` Avenue and the 8-inch water main on SE 2nd Street to 12-inch water mains or a contribution for future improvements. This will be determined during final design. C. Anticipated water use: The water use requirements for this project are calculated based on the build -out information previously described. An anticipated flow demand of 213,517 GPD is expected from this project. For determination of anticipated flows see Exhibit "C". 6 • • • MINIMINNINNINNI 11010011111111111. Since 1989 4. Sewer Collection System CIVIL LAND DEVELOPMENT TRAFFIC AND TRANSPORTATION A. Existing Sanitary Sewer System Facilities: Miami -Dade Water & Sewer Department (MD-WASD) owns and operates the following sanitary sewer facilities in the vicinity of this project: • Existing 15-inch and existing 24-inch gravity sewer lines along S. Miami Avenue. Those run along the entire westerly boundary of the project. • An existing 10-inch gravity sewer line along SE 2nd Street that runs along the entire northerly boundary of the project. • An existing 36-inch gravity sewer line along NE 1st Avenue that runs along the entire easterly boundary of the project. These lines collect all the sanitary flows from the general area and direct them to MD-WASD Pump Station # 30-0001. B. Required Sanitary Sewer System requirements: Based on the records provided by Miami -Dade Water and Sewer Department (MD-WASD) the existing sewer mains appear to be adequate to support the proposed development. This project will have to be analyzed by the MD-WASD Infill Committee to determine if additional extensions or contributions are required. That will be done at the time of permitting. 7 • • • MIL SINIIMNIMINIMINIONI AM 111MININIIIINIIIMIN MINIM0"-WrrErur NININIMMINO r � irr MIN fh} 6 Since 198 9 CIVIL LAND DEVELOPMENT TRAFFIC AND TRANSPORTATION C.
