PROJECT BACKGROUND
The City of Hallandale Beach is undertaking a stormwater management
project to address the existing pollution discharges into historical estuaries
designated as Outstanding Florida Water (OFW) in F.A.C. 62-302.700
(9)(f)66. The community is built out with no land for traditional treatment using
Best Management Projects (BMPs). The proposal is to construct pump
stations, baffle boxes, and additional collection system to direct polluted
stormwater to deep wells to reduce the pollutant levels prior to discharge to
the OFW. This project complements the City’s efforts to comply with the
current comprehensive plan and stormwater master plan, which addresses
the level of service, as well as water quality.

PROJECT GOALS AND OBJECTIVES
The projects main and primary objectives are as follow:
 Reduce the amount of nonpoint source pollution.
 Identify the causes and sources or groups of similar sources.
 Monitor and perform data analysis using Broward County’s Ambient
Surface Water Quality Network.
 Implement an educational program to enhance public understanding and
encourage participation.

PROJECT DESCRIPTION
The improvements to the existing drainage system will consist of the following
elements described below:
STRUCTURAL:
Drainage Pipes- Installation
improve the overall hydraulic
new system will increase the
greater volume of water to be
deep wells.
of a larger stormwater collection system to
and storage performance of the system. The
total attenuation of the system by allowing a
treated and stored before being discharged to
ExfiltrationTrenches- Trenches have been constructed in the new swale
areas to allow for increased storage, allow filtering through a filter fabric
wrapped around granular material, thereby removing various levels of
pollutants. The system will have perforated under-drains within graded
granular material wrapped in fabric and overlain with sod.
Baffle Boxes- The installation of the Baffle Boxes will provide additional
water quality treatment by removal of trash, litter, debris, sediment and
particulate pollutants. The first flush will be diverted into a bio-retention area
for the removal of finer particulate pollutants and dissolve pollutants including
phosphorus, nitrogen, suspended solids, heavy metals, oils and greases and
pathogens.
Swales With Raised Inlets Existing swales have been re-graded to create
additional storage with the tributary inlets set 3” higher than the swale bottom.
Improved retention time will result in a greater particulate settlement and
reduction of other stated pollutants
Control Structures- Installation of the proposed control structures will control
the discharge rates and will maximize the total storage capacity of the system
before discharging into the historical estuaries designated as Outstanding
Florida Water (OFW). This will be accomplished by directing the first flush of a
storm event to deep wells rather than discharging directly to the OFW.
Two (2) pump station- The proposed pump stations will improve the overall
hydraulics of the drainage system, alleviate local flooding and improve the
water quality prior to discharge.
10 Drainage Wells- The proposed wells will improve the overall water quality
and limit the amount of offsite discharge to the historical estuaries.
NON-STRUCTURAL:
Monitoring- The draft monitoring plan and agreement has been prepared in
accordance with the current requirements.
Educational- The City of Hallandale Beach will organize informational
workshops for the residential community. The workshops will increase public
awareness of the causes of stormwater pollution and will explain how local
agencies are implementing Best Management Projects to reduce stormwater
pollution. The City of Hallandale Beach will provide information via brochures
and educational pamphlets about the project at public meetings, the use of
signage, mail outs, press releases, and public events
MEASURABLE OUTCOME ANTICIPATED and PROJECT NEED
Water Quality improvements will reduce the yearly pollutant loads by 90%
prior to discharge. The water quality will also be improved for several other
listed parameters for this proposed stormwater management project.
Quantifiable targets of the project.
Water Quality improvements are vital to the project’s success and will be
implemented by reducing pollutants loads as shown in the Table below. The
percent of reduction is estimated to be 90% prior to discharging into the
historical estuaries. This improvement of water quality is also expected as a
result of the proposed stormwater management project.
