Site Utility Study
Introduction
The Seven 7 project is a proposed 17 story mixed use —commercial / residential
multi -family high rise building to be built on a total of 1.07 acres of land located at
2728 NE 2 Avenue, on West side of NE 2 Avenue between NE 27 Street and NE
28 Street. It is located in the City of Miami, Miami -Dade County, Florida (see site
location map -Fig 1). The development includes a residential tower constructed
on a parking garage/ commercial structure. It will consist of 88 residential
apartments units, 4,018 square feet of commercial area and 139 parking spaces.
Table 1, below depicts the details of the proposed project.

Figure 1
Existing Drainage
Presently, the site is undeveloped. There is no existing drainage systems on site.
Proposed Drainage System
The drainage systems for the proposed development will consist of drainage
wells and exfiltration trenches, if possible, to facilitate on -site disposal of storm
water runoff. The 5- year design storm event will be used to design the storm
water management system, in accordance with Section D-4, "Water Control", of
Part 2 of the Miami -Dade County Public Works Manual.
Seven 7 3
Site Utility Study
No topographic survey is available. The existing and proposal site elevations are
unavailable; therefore no preliminary drainage calculations are included in this
report. However, based on other projects in the area, it is anticipated that two (2)
24" drainage wells will provide sufficient capacity to dispose of the design 5-year
24-hour storm water runoff generated by the proposed development.
The final drainage design for the project should be in conformance with the
requirements of the Miami -Dade County DERM Water Control Section, Florida
Department of Environmental Protection, and the local, State , and federal
regulatory agencies having jurisdiction over the project.
II. Water Distribution System
The water mains owned and operated by the Miami -Dade Water and Sewer
Department (MDWASD) in the vicinity of the project are shown in the Table 2.

In accordance with MDWASD criteria, the owner will might be required to
construct a new 12-inch ductile iron (DI) water main along the frontage of the
property on NE 2 Avenue. A final determination of the points of connection and
requirements will not be provided by MDWASD until a Water and Sewer Service

Agreement is requested by the owner. Water service meters will be installed by
MDWASD forces at owner's expense.
See Attachment for a copy of the MDWASD water atlas sheet for the project area.
III. Sanitary Sewer Collection System
Table 3 depicts the sanitary sewer mains owned and operated by Miami -Dade
Water and Sewer Department (MDWASD) within the vicinity of the project.

A copy of the MDWASD Sewer Atlas sheet has been attached.
The proposed on -site sanitary sewer system for the property can properly be
connected to the existing public gravity mains. A final determination of the points
of connection and requirements will not be provided by MDWASD until Water and
Sewer Service Agreement is requested by the owner. A letter of availability from
DERM and further coordination with MDWASD is needed to verify the proposed
sanitary sewer service connection points and requirements for this project.
MDWASD may require upgrades to the sanitary sewer system, but this can not be
determined without a request for a water and sewer service agreement.
The flows from the existing MDWASD sanitary sewage mains on NE 2 Avenue are
received by MDWASD Regional Pump Station #2. As of September 2005, this
Seven 7

pump station is operating under capacity as established by the USEPA, and is not
under any type of moratorium. See Attachment for Pump Station Monthly
Information. At this time, it is not anticipated that any improvements to the regional
pumping and/or transmission systems will be required to connect the proposed
Project. However, a final determination regarding the status of the existing
transmission system and the need for possible improvements will not be made until
the construction plans are submitted to the Miami -Dade County DERM Wastewater
Section and a Sanitary Sewage System Capacity Certification Letter is issued.
The flows created by this project have been determined and are shown in Table 4.

IV. Solid Waste Generation
Solid waste generated by this project will be collected in standard on -site
containers for refuse and recyclables. Regular pick-up service will be provided
either by private hauling companies and/or by the City of Miami Solid Waste
Department, who will transport the waste to Miami -Dade County's or private
disposal and recycling facilities. The volumes of solid waste projected to be
generated are shown in Table 6.
