BOLD & GOLD Greenroof^TM was completed for the Honda Headquarters Building in Clermont Florida.  It was honored by www.greenroofs.com as their project of the week for January 2011.  The roof is about 4800 square feet of planted area using native vegetation of the central Florida area.  The roof was completed in early 2010.

Harvesting Curves

 Design curves to aid in predicting the volume of stormwater that can be collected from a watershed are site specific to an area.  These curves have been developed for many Florida locations and can be done for other locations.   To improve the quality of the storage water, BOLD & GOLD STORMWATER^TM, compositions D and P have been used.  An example of a design curve is shown.

Sub surface Upflow Filter

As an option to replace drainfields, sub-surface upflow wetlands (SUW) are being used.  They have an advantage of producing high reliability operation for nutrient removal.  An example cross section showing the different types of BOLD & GOLD Septic^TM media is shown in a cross section.  The media must be used together to provide a specific removal effectiveness over a long period of time (usually greater than 20 years).  The nutrient removal targets are both phosphorus and nitrogen species.

Residential Green Roof 

High visibility roofs sometimes referred to as active roofs as frequently found on residential homes.  The plants and media selection are important to maintain an aesthetic environment.  BOLD & GOLD GREENROOFS^TM with two types of media have proven to be successful in these locations.  Composition types C (contain pollutants) and G (growth media) are used in 16 different green roofs in the last three years by STE.  An example of plant selection is shown for a harsh sea side environment.  The system has proven to be maintainable as well as functional over a long period of time.

Filtration Media

Used in both public and private projects for a reduction in nutrients found in the discharge from lakes, detention ponds, and retention ponds.  There are five different projects, all were considered as the lowest cost technology.

Suntree Vaults

Suntree is a major supplier of stormwater pre-treatment devices.  To achieve additional solids and nutrient control, composition "V" is used in their upflow filter.  Go to Suntree Technologies for more information.

Tecta America Central Florida (aka General Works)

This project was brought to life with a 2,000 square foot greenroof in late February of 2008.  The project is located in Sanford Florida and build on a commercial building.  The greenroof was divided into two sections, each 1000 square feet, to show the use of both the tray greenroof system and the loose laid greenroof system.  Both systems were planted with 100% native plants specially selected to withstand the high temperatures and sun exposure.  Click here for more information.

Florida’s Showcase Green Envirohome

This project was brought to life with 5 greenroof areas totaling 896 square feet.  This residential application of greenroofs was an instrumental component of the near-zero discharge site design.  The project location is in Indialantic Florida so salt tolerance was an important factor when selecting plants.  The plants used on the greenroof areas were selected to withstand the salt environment as well as the high temperatures and high sun exposure.  The greenroof areas are irrigated with a combination of harvested stormwater from the site, greenroof filtrate, gray water, and groundwater from an onsite well.  All irrigation waters are stored in onsite cisterns for use for irrigation. Click here for more information.

This project was brought to life in May of 2007 with an 800 square foot greenroof.  This application was on a government building and was built to show that lightweight greenroofs can be designed and succeed in Florida.  The total saturated weight of this roof is about 20 lbs/ft² with a thickness of just 3 inches.  The plants used were 100% native and the roof is irrigated using recycled greenroof filtrate as well as gray water from a sink within the lab.  The project location is in Orland Florida at the University of Central Florida’s main campus.

Pervious Pavements

Pervious pavements can be used to reduce the volume and flow rate from a pavement area.   We have specialized in the testing and specification of these pavements in terms of their use for stormwater management.   Types that we have used on projects are classified as pervious concrete, flexipave ^TM, and permeable pavers.  We work to specify the total stormwater plan to include pollution control, volume control, mass balances, and flood control.  Working with Water Management, a runoff calculator was developed.
