Project Location and Size 305.858.8100 PH • 305.858.4760 FAX The proposed project consists of a Residential Condominium Tower to be constructed at an approximately 1.28 acre site located at 333 NE 24th Street, Miami 1 FI. (See Exhibit A). The project is bounded to the north by NE 25th Street, to the south by NE 24th Street, and to the west Biscayne Boulevard, all being in Section 30, Township 53 South, Range 42 East, Miami - Dade County, Florida. The site is partially occupied by single family homes, in its present condition. The homes will be razed for the new development. B. Proposed project build out: The proposed project build -out consists of 171 residential condominium units. Civil and Environmental Engineering • Permitting and Management • • • EDC Corp.

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 of 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) Environmental Resources Permit (ERP) requirements and the Florida Department of Transportation (FDOT). This will be accomplished by means of deep drainage wells. No offsite 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 local knowledge 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. C. Required number of Wells: The proposed wells will be designed to maintain the site dry during the 5 year-1 day storm, to keep flooding below the perimeter grades during the 25 year-3 day storm and to keep flooding below the minimum flood elevation during the 100 year- 3 day storm. Based on the attached calculations, a total of 4 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", Civil and Environmental Engineering • Permitting and Management • • EDC Corp.

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 12 inch water main on NE 25th Street that runs along the entire front side of the property. • An existing 12-inch water main on NE 24th Street that runs along the entire front side of the property. = An existing 16- inch watermain on Biscayne Boulevard. B. Required Water System Improvements: It Appears the existing Watermain System is adequate and additional offsite system improvements will not be necessary for the construction of this project. The proposed project should connect to the 12 inch watermain on NE 25th Street to obtain Domestic Water, Fire Protection and Landscape Irrigation service. C. Anticipated water use: The water use requirements for this project are calculated based on the build -out information previously described. An additional flow demand of 42,750 GPD (250 GPD/Unit) is expected from this project. For determination of anticipated flows see Exhibit "C".

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: • An existing 8-inch gravity sewer line along NE 25th Street that runs along the entire front of this property. This line collects all the sanitary flows from the general area and directs them to Miami -Dade Water and Sewer Department Pump Station # 02 located in Bicentennial Park. • An existing 72-inch interceptor gravity sewer line along NE 24th Street that runs along the back side of this property. This line collects all the sanitary flows from the general area and directs them to Miami -Dade Water and Sewer Department Pump Station # 02. B. Required Sanitary Sewer System Improvements: MD-WASD Gravity Sewer System requirements: It appears that the existing Sanitary Sewer Collection System is adequate and additional offsite system improvements will not be necessary for the construction of this project. The proposed project should connect to the existing 8-inch gravity main to obtain sanitary sewer service. C. Transmission Capacity Requirements The Wastewater generated by this project will be conveyed to MD-WASD Regional Pump Station No. 02. This station have a yearly NAPOT of 4.22 hours per day respectively according to DERM. (See Exhibit "C). The current ET data as of May 2004 reflects 4.22 hours. With an additional flow of 42,750 gallons per day generated by this project, the station will only increase by 0.02 hours to 4.24 hours. The above referenced pump station has sufficient available capacity to support this project. Flows from this Pump Station are transmitted to the MD-WASD Treatment Plant at Virginia Key.
