Project Location and size: The proposed project consists of a Multi -use Facility to be constructed at an approximately 9.07 acre site in downtown Miami. The project limits are: to the west NW 3rd Avenue to the north NW 8th Street to the east NW 1st Court to the south NW 6th Street. The property consists of four separate blocks separated by NW 7th Street and NW 2nd Avenue. The property being in Section 1, Township 54 South, Range 41 East and , Section 36, Township 53 South, Range 41 East Miami -Dade County, Florida. B. Existing Conditions: The property consists of four separate blocks separated by NW 7th Street and NW 2" Avenue. In its existing condition the parcels are considered vacant. in the past this site was occupied by approximately 400 residential apartment units. 3 • • mome;n orsoommommew PM m L now L , IniC!._..__ Sine(' 1989 CIVIL LAND DEVELOPMENT TRAFFIC AND TRANSPORTATION C.

Storm Drainage System A. Existing Storm Drainage System: CIVIL LAND DEVELOPM-N1 "IRAFFIG AND TRANSPORTAT N 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. 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) requirements. This will be accomplished by means of deep drainage wells. No off- site run-off will be generated from this project. 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. • 5 • • v�„ serafforamiwwgsw NMI a rr v.r— Since CIVIL LAND D VFLOMENT TRAFFIC AND TFIANSPORTAii N C. Required number of Wells: 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 nine (9) --- 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". 6 rm�r L�r--•tea setwoms momimmift r, i CiViL LA -1 € ND DEVELOPMENT TRAFFIC AND TRANSPORIATION Since 1989 3. Water Distribution System A. Existing Water System Facilities: Miami -Dade Water & Sewer Department (MD-WASD) owns and operates the following domestic water facilities in the vicinity of this project: • An existing 16-inch water main on NW 8u1 Street that runs along the entire northerly boundary of the project. • An existing 12-inch water main on NW 1s1 Court that run along the entire easterly boundary of the project. • An existing 16-inch water main on NW 7th Street that runs along the entire center of the project. • An existing 16-inch water main on NW 3rd Avenue that runs along the entire westerly boundary of the project. • An existing 12-inch water main on NW 2nd Avenue that runs along the entire center of the project. These existing water mains can be used to provide fire protection domestic and landscape irrigation service for this project. The existing water distribution system in the vicinity of this project will have to be evaluated 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 Infill Committee will make an evaluation of the system and may require additional system improvements. This will be determined during final design. 7 MOM , f7MMONANININNIONNIN MUM \\If/...„,,MONINOMNIMONOMM AMMONIUM .,1-'1AINIONONINNO ANNOONNIM ANONNINNIONNM MAIMAINNINIMOOMMM • • 4 [Cp ®� Lrj Pqg 7 1 " luinlcc;H I 1 Since 1989 C.

These lines collect all the sanitary flows from the general area and direct them to MD-WASD Pump Station # 30-001 or 30-002 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. No additional sanitary system improvements are expected. The Sanitary Sewer System in the vicinity of this project will have to be evaluated by the MD-WASD to determine if additional extensions may be required. That will be done at the time of permitting. 9 Okatik MEINIEWEINOW117 MOOMOrk ''sjar—,1111111 3•014#10. Mill1001116111 /11111111141•111111M.- 11101111011111.110011100 3.1..4111.1.11....01. MINIM .

These are major pump stations with a yearly NAPOT of 2.93 hours per day as of November 2005 according to DERM. (See Exhibit "C"). The impact of this project on the ET of these stations is 0.05 and 0.17 hours respectively. The expected ET will be 6.66 and 4.83 hours which is less than the allowed 10 hours. Pump Stations No. 30-001 or 30-002 at this time has sufficient available capacity to support this project. • • 10 =Ma ARIMANIMPIMMIMOt MEM \ t IIMECOMMINIS WNW U.ar---.01WININHOLIN MINROOKONONIR INIWINIMMATA-.1_ FIRMA 111111111111111111MININI Since 1989 5.
