SUSTAINABILITY THROUGH BIOMIMICRY
Biomimicry (from bios, meaning life, and mimesis, meaning to imitate) is a design discipline, that when intrinsic to stormwater systems, reintroduces natural systems into the built environment. This “green infrastructure” will provide flood control during heavy rain events, when soil saturation has peaked, mimicking natural ecosystems for pollutant removal, such as fertilizers, petroleum products and surface contaminants.
As our freshwater supply becomes increasingly taxed, letting minimally remediated and reusable water run “down the drain, ultimately to Lemon Bay, isn’t a balanced biological system in which plants and animals can thrive. By utilizing nature as the template, scientists, engineers, architects and county staff have innovatively modeled new sustainable technologies for the West Dearborn Street Low Impact Development Pilot Program.

These functions include linear bioretention located in the roadside public right of ways. Sources of run-off are diverted into these swales, removing pollutants by filtration, absorption to soil particles and biological uptake by plants and microbes. Contact with soil and roots provide water quality treatments better than conventional methods, with removal of up to 75% of phosphorus and nitrogen, 95% of metals and 90% of organic bacteria and total suspended solids.
The stormwater runoff will be harvested to irrigate the vegetated bioswales and landscaped areas. A portion of the runoff will first be captured and stored in the 24” re-use pipe below the swale, to then overflow into the 8” perforated pipe for infiltration into the surrounding soil. As capacity is exceeded, and soil saturation has peaked, then each block of bioswales will discharge under side streets to fill the entire grid of the Dearborn Street storm-water system. On those periodic, continual rain events, water may eventually make its way Lemon Bay, filtrated in quality that biomimics its pre-development attributes. Sustainability

GREEN ROOFS IN THE DEARBORN STREET ECO-DISTRICT
Marrying the built to the natural environ-ment, the Freedom Pavilion is truly rooted in the community. As a component of the Low Impact Design Draft Manual, The Freedom Pavilion is an intensive green roof stormwater treatment system as it is irrigated with a cistern where the roof filtrate will be used for irrigation. While non-irrigated systems are possible, the extremely hot temperatures here coupled with drought conditions will not ensure a vibrant plant population. For a greenroof to function as a stormwater treatment system, this integral part of the treatment train must be vigorous and constant. Vegetation will help reduce total phosphorus, ortho-phosphorus, TKN, and total nitrogen concentrations. Wicking water away from the root zone during heavy and frequent rain events and providing watering during dry periods are essential for vigorous plant growth. The use of the cistern will promote denitrification and greatly reduce the volume of runoff leaving the system, with this greatly reduced flow into the adjacent bioswale left very few

Providing wildlife habitat- butterflies, bees and other pollinating insects frequent the roof on a continual basis.
· Supporting biodiversity
· Creating habitat for endangered plants that are native to Florida and capable of nutrient uptake through root rizomes
· Integrated pest management – tree frogs and anoles inhabit the roof providing pest control of flies, termites and roaches
· Mitigating Urban heat islands-the roof provides approximately 40 degrees F insulating qualities over non-vegetated roofs. While providing shade, they actually remove heat from the air through evapotranspiration, reducing temperatures of the roof surface and the surrounding air. A conventional rooftop can be up to 90 degrees F warmer.

SUSTAINABILITY THROUGH TREE CANOPIES
Due to limited planting areas that can accommodate 1000 cf of loam soil, the 30 year lifespan of a typical canopy tree is reduced to 7 years in the urban environment. Coupled with the disruption and financial impact of frequent re-plantings, the environmental benefits of mature trees will never be realized.
Silva Cells can provide a modular, structural framework that supports vehicular pavement above while providing chambers for root growth, soil, stormwater retention and utilities below. The soil within the cells can retain significant amounts of water to filter a wide range of pollutants, the tree growth.
Environmental: air and water filtration, carbon sequestration, storm water retention, reduced energy consumption, wildlife habitat
Economic: reduce infrastructure costs, energy savings, increase real estate values, promote consumer spending, amenity appreciation
Sociological: define and strengthen neighborhoods, reduce crime rates, increase health and well being
BENEFITS OF LIDL
• Preserve open space and minimize land disturbance
• Protect natural systems and processes (drainage ways, vegetation, soils, sensitive areas)
• Re-examine the use and sizing of traditional site infrastructure
• Incorporate natural site elements (wetlands, stream corridors, mature forests) as design elements
• Decentralize and micromanage storm water at its source. Reduce pollutant loading/TMDL compliance
• Protect regional flora and fauna
• Balance growth needs with environmental protection
• Reduce municipal infrastructure and utility maintenance costs (streets, curbs, gutters, sidewalks,
storm sewers, storm water collection vaults, retention/detention ponds.)
