Storm Drainage System A. 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 and the Florida Department of Transportation. 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 or 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) and The Florida Department Of Transportation (FDOT) requirements. This will be accomplished by means of deep drainage wells. No off- site 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. • • • err -1v 111____R Nam !r r 1111111111111M. 1.0rrn11= _ ram•.. ®I[lj fih1®® I Since 1989 C L' J CIVIL LAND DEVELOPMENT TRAFFIC AND T3ANSPORTATiON 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. 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 6 — 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" 5 • • • wrrr1M MOM r r IMINIMIMPIO Since I989 3. Water Distribution System CIVIL LAND DEVELOPMENT TRAFFIC AND TRANSPORTATION 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: • Existing 12-inch water main on SE 2nd Avenue and Biscayne Blvd (SE 4th Street) that runs northerly from this intersection. • An existing 12-inch water main on SE 4th Street that runs easterly along SE 4th Street from SE 2nd Avenue to SE 3rd Avenue. • An existing 24-inch water main on SE 4th Street that runs easterly from SE 3rd Avenue along the front of the property. • An existing 8" water main that runs along SE 4th Street along the entire length of the property. These existing water mains can be used to provide fire protection domestic and landscape irrigation service for this project. B. Required Water System Improvements: As stated in the MD-WASD availability letter dated September 12, 2003, (See Exhibit "C"), the existing Watermain System is adequate for the connection of the proposed Domestic Water, Fire Protection and Landscape Irrigation services for the project. A 12" watermain extension along SE 2" Avenue from SE 4th Street south to the end of the property will be required by MD-WASD. C. Anticipated water use: The water use requirements for this project are calculated based on the build -out information previously described. An anticipated flow demand of 238,798 GPD is expected from this project. The previous flow demand from the existing hotel is 88,861 GPD. The net increase in demand from this project is 149,937 GPD. For determination of anticipated flows see Exhibit "C". 6 • • I. - - errarrr Since 1 989 CIVIL LAND DEVELOPMENT TRAFFIC AND TRANSPORTATION 4. Sewer Collection System A. 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 36-inch gravity sewer line along SE 2nd Street, a 21-inch and a 24-inch gravity sewer on Biscayne Blvd and 10-inch and 15-inch gravity sewer lines on SE 4th Street which will serve the proposed development. This lines collect all the sanitary flows from the general area and direct them to Miami -Dade Water and Sewer Department Pump Station # 30-0001. B. Required Sanitary Sewer System improvements: MD-WASD Gravity Sewer System requirements: As stated in the MD-WASD availability letter dated September 12, 2003, (See Exhibit "C"), the existing Sanitary Sewer Collection System is adequate and additional offsite system improvements will not be necessary for the construction of this project. The proosed project could connect to any of the existing gravity mains o SE 4th Street to obtain sanitary sewer service for the project. C. Transmission Capacity Requirements The Wastewater generated by this project will be conveyed to MD-WASD Regional Pump Station No. 30-0001. This is a major station with a yearly NAPOT of 4.63 hours per day according to DERM. (See Exhibit "C") The current ET data as of 9/24/03 reflects 6.09 hours which is less than the allowed 10 hours. Pump Station No. 30-0001 at this time has sufficient available capacity to support this project. Flows form this Pump Station are transmitted to the MD-WASD Treatment Plant at Virginia Key. 7 • • • ii i jni®E@ ni ? Since 1989 CIVIL LAND DEVELOPMENT TRAFFIC AND TRANSPORTATION 5. Solid Waste Generation A. Solid Waste Generated by this project will be collected in standardized on - site containers for refuse and re-cyclables. 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 43 CY per day.
