General A. Project Location and Size The proposed project consists of a Residential Condominium Tower to be constructed at an approximately 1.76 acre site located at 700 Biscayne Boulevard, Miami I FI. (See Exhibit A). The project is bounded to the north by NE 8th Street, to the south by NE 7th Street, and to the east by Biscayne Boulevard, all being in Section 31, Township 53 South, Range 42 East, Miami - Dade County, Florida. The site is vacant, in its present condition. B. Proposed project build out: The proposed project build -out is mixed use and consists of 467 residential condominium units, 120 guest hotel/condo suites, 7,297 square feet of restaurant services, and 12,947 square feet of retail/office space.

Storm Drainage System 305.858.8100 PH • 305.858.4760 FAX A. Existing Storm Drainage System: Roadway storm drainage systems presently exist along the streets surrounding the proposed project. FDOT owns right of way and drainage systems along Biscayne Boulevard. The side Streets and associated drainage 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 (ERF) 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 800 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.

Environmental Development Consultants Corporation 2455 SW 27'h Avenue, Suite 300 305.858.8100 PH • 305.858.4760 FAX Miami, Florida For Well Disposal System calculations refer to attached Exhibit "B". 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 12-inch water main on NE 8th Street that runs along the entire north side of the property. An existing 8-inch water main on NE 7th Street that runs along the entire southt side of the property. • An existing 24- 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. WASAD will determine the exact points of connection. The proposed project should connect to the 12 inch watermain on NE 8th 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 136,897 GPD for the residential and office components 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 27-inch gravity sewer line along Biscayne Boulevard 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 24-inch gravity sewer line along NE 8th Street that runs along the north 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 24-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 has a yearly NAPOT of 4.32 hours per day respectively according to DERM. (See Exhibit "C). The current ET data as of February 2005 reflects 4.32 hours. With an additional flow of 136,897 gallons per day generated by this project, the station will increase by 0.09 hours to 4.41 hours.

Flows from this Pump Station are transmitted to the MD-WASD Treatment Plant at Virginia Key. 5. Solid Waste Generation A. Solid Waste Generated by this project will be collected in standardized onsite-containers for refuse and recycle. Either hauling companies and/or the City of Miami Solid Waste Department will provide regular pick— up services. The anticipated daily solid waste generation for this project is 21.2 CY per day (See Appendix "D"). Civil and Environmental Engineering • Permitting and Management • • EDC Corp.
