GENERAL 1080 BRICKELL DEVELOPMENT SITE UTILITY STUDY A. Project Location and Size: The proposed development consists of a residential tower and parking garage. The parent tract of the project is located at the southerly 200.00 feet of the northerly 400.00 feet of lot 6, less the easterly 10.0 feet thereof, block 100S, amended map of Brickell's addition to the map of Miami, according to the plat thereof, as recorded in Plat Book B, at page 113, of the public records of Miami - Dade County, Florida, in Section 12, Township 54 South, and Range 41 East, The site is bounded by Brickell Avenue to the east, and SE Miami Avenue to the west, an adjacent building to the south, a parking lot to the north, and consists of 1.569 acres more or less. The parent site is currently occupied by a parking garage and a nine story office building. The existing office building will remain, and the parking garage will be demolished to accommodate the new 1080 Brickell Development. B. The development program for the project is as follows: Apartments: 315 PBS&J January 2006 • • • 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 parent site is occupied by a nine story office building and two level parking garage. A concrete sidewalk abuts Brickell Avenue, and SE Miami Avenue. The site has an asphalt parking area adjacent to the existing building 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, three (3) 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 January 2006 • • • 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 SE Miami Ave. SE 12th St to SE 8th Street 12" Brickell Avenue SE 13th St to SE 8th Street 20" and 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 63,000 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 January 2006 • • • 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 Brickef Ave. SE 13th St SE 8th Street 10" So Miami Ave SE 12th St and SE 11th St 8" The wastewater collection system flows by gravity and connects to the regional WASD pump station 30-0008 or 30-0001. B. Projected Waste Water Demand: Average Daily Flow (from Table 1) 63,000 gpd Average Flow (gallons per minute) 44 gpm Projected Peak Flow (3.5 peak factor) 154 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.
