GENERAL A. Project Location and Size: The proposed development consists of a residential tower and parking garage with some retail and restaurants. The project is located at Lots 1 through 7, inclusive, Block 119N, A.L. Knowlton's Map of Miami, Plat Book B, page 41 Miami -Dade County, Florida, in Section 6, Township 54 South, and Range 42 East. The site is bounded by Biscayne Boulevard to the east, NE 1st Street to the north, NE 3rd Avenue to the west, and East Flagler Street to the south, and consists of 1.2978 acres more or less. The site is currently occupied by a shopping center that consists of four one story concrete block buildings. These existing buildings will be demolished to accommodate the new Columbus Residential Tower. B. The development program for the project is as follows: Apartments: 517 Retail Shops : 5,727 GSF Full Service Restaurant: 500 seats Health Club/ Spa/Gym 17,700 SF PBS&J July 2004 • • • 2. STORM DRAINAGE SYSTEM A. Existing Storm Drainage System The City of Miami presently maintains the roadway drainage system around the site. The storm water runoff from the existing roadway is directed and conveyed into the City drainage system. The existing site is occupied by four one story buildings. A brick sidewalk abuts Biscayne Boulevard, and concrete sidewalks along the remaining three sides. The site has an asphalt paved area in between the buildings with catch basins, and does not appear to contribute any significant amount of storm water run-off into the public roadway system. B. Proposed On -Site Storm Drainage System Storm water discharge from the proposed development area will consist mainly of building roofs, building walls, driveways and landscape area run-off. After development the site is assumed to be approximately 95% impervious. The primary drainage system for the project will consist of drainage wells. The rainfall runoff will be conveyed by the series of roof drains, rain -water leaders and plumbing pipes to the drainage wells. It is anticipated that an Environmental Resource Permit (ERP) will not be required for stormwater runoff, as the site area is less than two acres. However, it is assumed that for the site drainage permit the 5-year, 25-year and 100-year, 3-day storm events are to be considered. The total contributing area for stormwater will consist of the site area, and 30% of two sides of building wall area which are exposed to the rain at any given time. This criteria would be used for determining the number of wells. Based on data provided by local experienced well drilling companies, a 600 to 750 gpm per foot head of discharge rate can be expected, for the wells. C. Storm Drainage Wells: Based on the above criteria and assumptions, four (4) drainage wells would be required for the site, depending on the actual yields obtained during the well drilling operations. For storm drainage calculations refer to the attached Exhibit 'A'. PBS&J Page 2 July 2004 • • • 3. WATER DISTRIBUTION A. Existing Water System Facilities: The Miami -Dade Water and Sewer Department (MD-WASD) owns and operates the following water mains in the vicinity of the project. Location Between Water Main(s) Diameter Biscayne BI NE lst St to East Flagler 24", 12" and 6" NE 1st St NW 3rd Ave to Biscayne BI 20" NE 3 rd Ave NE lst St to East Flagler 12" and 4" East Flagler NE 3rd Ave to Biscayne BI 6" The project sites are surrounded by water mains of 12" and larger diameter. At locations of two water mains on the same street, WASD will require connection to the larger diameter water main. The water extensions if required would be determined by MD-WASD. A fire hydrant flow test is recommended. B. Water Demand The anticipated water demand for the project is 134,882 gpd. The development plan with its water demands is shown in Exhibit `B'. C. Required Water System Improvements: An application has been made to the Miami -Dade Water and Sewer Department for the water and sewer availability letter. This would outline the points of connection for the water and sewer. Any water main extensions constructed by the developer as a requirement of this project would have to be conveyed to MD-WASD. PBS&J Page 3 July 2004 • • 4. WASTEWATER COLLECTION A. Existing Sanitary Sewer Collection System: The Miami -Dade Water and Sewer Department (MD-WASD) owns and operates the following gravity sewer collection mains in the vicinity of the project. Location Between Sewer Main(s) Diameter Biscayne BI NE 1st St to East Flagler 16" and 10" NE lst St NE 3rd Ave to Biscayne BI 12" NE3rdAv NE 1st St to East Flagler 8" East Flagler NE 3rd Ave to Biscayne BI 16" The wastewater collection system flows by gravity and connects to the regional WASD pump station No 2. B. Projected Waste Water Demand: Average Daily Flow (from Table 1) 134,882 gpd Average Flow (gallons per minute) 94 gpm Projected Peak Flow ( 3.5 peak factor) 328 gpm C. MD-WASD Availability letter: An application has been made to the Miami -Dade Water and Sewer Department for the sewer availability letter, for the project. PBS&J Page 4 July 2004 • • • 5.
