Project Title: San Marco and Biscayne Islands Drainage Improvements (B-30588)
Project Location:
San Marco and Biscayne Islands located in Miami, Florida
Project Background:
The Venetian Islands are a chain of six artificial islands in Biscayne Bay nestled between the
cities of Miami and Miami Beach, Florida. Biscayne and San Marco Islands are the first and
second westernmost chain of artificial islands constructed on the bay during the early 1900s. The
islands are connected by bridges from the Florida mainland to Miami Beach. Home to multi-
million dollar estates, these islands are in a low-lying area and prone to flooding during a severe
storm event. The construction of drainage systems on these islands will alleviate water damages
caused by flooding and provide relief to property insurances.
Project Objectives:
• Objective 1: The drainage improvements include but not limited to deep injection
drainage wells, storm water pump stations, storm sewer pipe connections to new outfalls,
weirs, baffles, manholes, catch basins, cross drains, swale trenches and surface
restoration. Note: Storm water from this project discharges to the Biscayne Bay.
• Objective 2: Pre-treatment of the surface runoff prior to discharge into the bay. As the
runoff enters the storm drain system, sumps in the storm structures will provide the initial
collection of sediments along with baffle structures to retain hydocarbons. In addition,
deep injection drainage wells will be constructed within the project site that serves to
reduce water quantity and improve water quality. Weirs, baffles, and detention structures
are constructed immediately upstream of the deep injection wells to reduce pollutants
prior to discharge into the wells for water quality rather than allowing free discharge.
Deep injection drainage wells may provide approximately 75% reduction of total
suspended solids (TSS), 50% reduction of total nitrogen (TN) and 55% reduction of total
fromrunoffprior to the -outfalls. ---Also,----the--C-ity -maintains five (5)
phosphorous-(TP)
Vactor trucks and crews that will clean on a rotating schedule all drainage structures as
required by the City's NPDES Permit. Not only will it remove all accumulated debris
and silt, it optimizes the operation of the drainage system.

Project Description:
The scope of the project consists of the construction of storm sewer improvements in local
streets within San Marco Island and Biscayne Island in the City of Miami. The improvements
include but are not limited to deep injection drainage wells, storm sewer pipes, storm water
pump stations, connections to new outfalls, weirs, baffles, manholes, catch basins, cross drains,
swale trenches and surface restoration. Note: Storm water from this project discharges to the
Biscayne Bay. Biscayne Bay is a SFWMD priority water body.
