Project Location and size: The proposed project consists of a Multi -use Facility to be constructed at an approximately 1.43 acre downtown Miami. The project limits are: to the west private property, to the north NE 25th Street to the east Biscayne Blvd to the south NE 24th Street. The property being in Section 30, Township 53 South, Range 42 East, Miami - Dade County, Florida. B. Existing Conditions: The entire site consists of 10 different lots. in its existing condition one is being used as commercial establishment totaling approximately 2,487 sf of usable space the other nine lots being used as residential units 3 • • • NMI r�rr�rs plow rr rrrr+rr r' -NsmisImmwmim Ewa arrrrrr Mot Cil Since 1989 In 0 CIVIL LAND DEVELOPtENT TRAFFIC AND TRANSPORTATION C. The proposed project build -out will be as follows: Condominium Apartments 214 Units Commercial Retail 7,000 sf Office 14,000 sf Restaurant 100 Seats 4 Since 1989 2. Storm Drainage System A. Existing Storm Drainage System: CIVIL LAND DEVELOPMENT TRAFFIC AND TRANSPORTATION 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) 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. 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. • • • • IOW INI=ICIMMINOMPWR Since 1989 C. Required number of Wells: CIVIL LAND DEVELOPMENT NT TRAFFIC AND TRANSPORTAT)ON 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. Also, the wells will be designed to contain the entire run-off for the Critical Storm Event to meet the FDOT requirements since the project is adjacent to an FDOT facility. Based on the attached calculations, a total of one (1) — 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" 8550 W.

Existing Water System Facilities: CIVIL LAND DEVELOPMENT TRAFFIC AND TRANSPORTATION 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 and an exiting 2-inch water main on NE 25m Street that run along the entire northerly boundary of the property. The 12- inch water main ends a short distance west of Biscayne Blvd and turns into a 2" water line. • An existing 12-inch water main on NE 241h Street that run along the entire southerly boundary of the property. • An existing 16-inch water main on Biscayne Blvd. that run along the entire easterly boundary of the property. These existing water mains can be used to provide fire protection domestic and landscape irrigation service for this project. This project will have to be reviewed by the MD-WASD lnfill Committee to determine if additional extensions or contributions are required. That will be done at the time of permitting. B. Required Water System Improvements: Based on the records provided by Miami -Dade Water and Sewer Department (MD-WASD) the existing water mains appear to be adequate to support the proposed development. MD-WASD Infill Committee may require additional system improvements to upgrade the 2" water main on NE 25th Street, or a contribution for future improvements. This will be determined during final design. 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 49,550 GPD is expected from this project_ The previous flow demand from the existing buildings is 3,399 GPD. The net increase in demand from this project is 46,151 GPD. For determination of anticipated flows see Exhibit "C". 7 : r.rr. �rrr.e • • Since 1989 4. Sewer Collection System CIVIL LAND DEVELOPMENT TRAFFIC AND TRANSPORTATION 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 72-inch gravity sewer line along Biscayne Blvd. that runs along the entire easterly boundary of the project. • An existing 8-inch gravity sewer line along Biscayne Blvd. that runs along a portion of easterly boundary of the project. • An existing 30-inch gravity sewer line along NE 25th Street that runs along the entire northerly boundary of the project. • An existing 8-inch gravity sewer line along NE 24th Street that runs along the entire southerly boundary of the project. These lines collect all the sanitary flows from the general area and direct them to MD-WASD Pump Station # 30-0002. B. Required Sanitary Sewer System requirements: Based on the records provided by Miami -Dade Water and Sewer Department (MD-WASD) the existing sewer mains appear to be adequate to support the proposed development. No additional sanitary system improvements are expected. 8 VIM f1O111►1�irf IMP • • ®G Since 1989 CIVIL LAND DEVELOPMENT TRAFFIC AND TRANSPORTATION C. Transmission Capacity Requirements The Wastewater generated by this project will be conveyed to MD-WASD Regional Pump Station No. 30-0002. This is a major station with a yearly NAPOT of 5.21 hours per day as of June 2004 according to DERM. (See Exhibit "C"). The impact of this project on the ET of this station is 0.03 hours. The expected ET will be 5.24 hours which is less than the allowed 10 hours. Pump Station No. 30-0002 at this time has sufficient available capacity to support this project. 9 • • • MINI r' -err IIIIIIIPIIIIMF NI IIIMEMMIMINOi rL ,fie ® n'c®j L l I V Since 1989 5.
