This manual, developed specifically for southeast Florida, contains information on designing low-impact development and green infrastructure projects at local scales.

MIAMI, FL – In partnership with the University of Florida Program for Resource Efficient Communities, the Florida Department of Environmental Protection (DEP) Coral Reef Conservation Program created a Low-Impact Development/Green Infrastructure (LID/GI) manual that provides an overview of potential strategies to reduce and manage land-based sources of pollution at a local project scale in southeast Florida.

The manual includes information on local hydrology and geology and empowers users, including local governments, stormwater management districts and engineering professionals, to make informed decisions about LID/GI projects in southeast Florida. A companion reference matrix helps users compare and evaluate specific characteristics of different stormwater-control options to identify appropriate options for specific sites. The matrix tool lists each LID/GI option relevant to the region and describes the benefits, site applicability and implementation considerations.

“Municipalities can use the reference matrix and manual to weigh costs and benefits of different low-impact development and green infrastructure projects,” said DEP Coral Reef Conservation Program Manager, Jamie Monty. “This user-friendly approach provides relevant information decision-makers need to implement effective small-scale projects with limited resources.”

DEP’s Coral Reef Conservation Program has been working on specific engineering and management actions for watersheds in southeast Florida that have been identified as high management priorities. Pilot projects are under way throughout the Boynton Inlet Contributing Area (see map below) to demonstrate what can be achieved with minimal resources.

These local LID/GI pilot projects often involve retrofitting existing developments. Popular retrofitting projects include rain gardens with Florida-friendly or native plants that slow water flow, and vegetated swales that collect and transport stormwater. In new developments, designing compact buildings can keep land free for green infrastructure and public spaces.

Using LID/GI locally can improve the quality of water reaching downstream ecosystems. Low-impact development, green infrastructure, controlling pollutants at the source, careful site planning in new and redeveloping areas, and use of stormwater control measures have the potential to mitigate some of the most adverse effects of land-based sources of pollution on water quality. Good water quality is critical for the coral, mangrove, seagrass and oyster habitats in southeast Florida.
