SITE UTILITY STUDY
A. Project Location and size:
The proposed project consists of a Multi -use Facility to be constructed at an
approximately 3.51 acre site located at the north west corner of Brickell
Avenue and SE 7th Street, in downtown Miami designated as Block 107A of
"BRICKELL ADDITION OF MAP OF MIAMI" as recorded in Plat Book B,
Page 113, Miami -Dade County, FI. (See Exhibit "A").
The project limits are: to the west the Metro -Rail Tracts, to the north is SE 6th
Street, to the east Brickell Avenue (an FDOT road) and to the south SE 7th
Street (also an FDOT Road). All these being in Section 1, Township 54
South, Range 41 East, Miami -Dade County, Florida.
B. The site in its present condition is being used an Office Building. The
existing uses are as follows:
Office 82,033 Sf
Restaurant (Full Service) 136 Seats
Restaurant (Fast Food) 64 Seats

2. Storm Drainage System
CIVIL
LAND DEVELOPMENT
TRAFFIC AND TRANSFORTAT}ON
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. Tile 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
requirements of the City of Miami Public Works Department, Miami -Dade
County Department of Environmental Resources Management (DERM)
Environmental Resources Permit (ERP) and The Florida Department Of
Transportation (FDOT). 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 rainfall 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.

TRAFFIC AND TRANSPORTATION
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 from shedding any run-off into the
adjacent FDOT roadways during the 100 year- 3 day storm event.
Based on the attached calculations, a total of 7 — 24" diameter storm
drainage wells are required to provide full on -site retention for both
phases of this project. This is subject to change depending on the actual
yields obtained during the well drilling operations.
It is expected that four (4) wells would be required for Phase 1 and three
(3) wells for Phase 2.
For Well Disposal System calculations refer to attached Exhibit "B".

3. Water Distribution System
A. 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 6-inch water main on SE 6th Street that runs westerly from
Brickell Avenue along the entire length of the property.
• An existing 20-inch water main on Brickell Avenue that runs southerly
along the entire length of the property.
• An existing 8-inch water main on Brickell Avenue that runs .southerly
along the southern half of the property.
• An existing 8"-inch water main on SE 7th Street that runs westerly
along the entire length of the property.
B. Required Water System Improvements:
As stated in the MD-WASD Memorandum dated December 29, 2005,
(See Exhibit "C"), the existing Watermain System in the vicinity of the
project will require the following improvements for the development of this
project:
• A 12" watermain extension along SE 6th Street from an existing 12" Water
Main on Brickell Avenue and interconnecting to an existing 12" Water
Main on SE 1st Avenue.
• A 12" watermain extension along SE 7th Street from an existing 20" Water
Main on Brickell Avenue and interconnecting to an existing 8" Water Main
at the west end of the project. This Water Main extension would be
required only if the City of Miami Fire Department requires the installation
of a new Fire Hydrant on SE 7th Street. This would be determined pending
review of Fire Fio'vV tests 011 the existing 8" VVater IVI!I1.

If the MD-WASD recommendations are implemented, the Water Mains in the
vicinity of this project would be adequate to support the proposed
development.
MD-WASD Infill Committee will make the final evaluation of the system to
determine the required system improvements for this project considering the
requirements of the City of Miami Fire Department.
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 174,892 GPD is expected from this project.
The previous flow demand from the existing Office Building is 17,243
GPD. The net increase in demand from this project is 157,649 GPD.
For determination of anticipated flows see Exhibit "C".

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 8-inch gravity sewer line on SE 6th Street that runs
westerlyalong the entire length of the project.
• An existing 8-inch gravity sewer line on Brickell Avenue that runs
northerly along the entire Length of the project.
• An existing 8-inch gravity sewer line on Brickell Avenue that runs
southerly along the south half of the project.
• An existing 8-inch gravity sewer line on SW 7th Street that runs
westerly along the entire length of the project.
These 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-WAS.D Gravity Sewer System requirements:
As stated in the MD-WASD Memorandum dated December 29, 2005,
(See Exhibit "C"), the existing Gravity Sewer System in the vicinity of the
project will require an engineering analysis MD-WASD to determine if any
improvements to the collection system are required for the development of
this project. This process is being conducted at this time.

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 an
existing operating time of 6.89 hours per day as of January 2006
according to DERM. (See Exhibit "C")
With the addition of the flows from this project the projected operating
time of this station will increment 0.03 hours to 6.92. This is well below the
10 hour maximum allowable operating time.
Pump Station No. 30-0001 at this time has sufficient available capacity to
support this project.
Plows form 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 willbe 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 54 CY per
day. (See Appendix "D").
It is expected that 23.5 CY would be generated by Phase 1 and 30.5 CY
would be generated by Phase 2.
