We transformed contaminated land into a community asset at State Road 71 and US-90 intersection in Marianna, Florida. Previously, an empty lot held tainted soil and groundwater. Our team reformed the land into a place that empowers the community and provides long-term economic opportunities. Before we upgraded the site, the Florida Department of Environmental Protection (FDEP) required an impermeable cap. It designated part of the property as “restricted property” to fix the pollution. The cap worked like the one on a water bottle, limiting future health dangers.
Goodwood Museum and Gardens has dealt with serious storm damage for years because of poor drainage. Heavy rain often washes away gravel from walkways and parking lots, costing the museum a lot of money to fix. Since the museum runs on a tight budget, these repairs are difficult to afford. Another big issue is flooding in the basement of one of the buildings, where water seeps through the walls.
The Grayton Beach State Park Concession Building in Walton County, Florida, was built to make the park more accessible to visitors by adding a concession area by the campgrounds. Before this project, visitors had to leave the park for food, restrooms and camping supplies. We designed this building to blend with the park’s environment, offering outdoor seating, scenic views and public bathrooms. The most significant challenge during the project was compiling information from multiple sources, including structural guidelines, building codes and stormwater requirements.
After it was built, Rosa’s Community Garden (RCG) helped people in Jackson County, Florida, get fresh food and health services. In 2022, about one in five residents lived in poverty, 6.7% higher than the national average. The garden allowed people to grow food, learn new skills and connect with others.
Seminole Finances has a new home following the completion of construction at Summit East. The development provides office space within Summit East Technology Park that serves as a professional and welcoming place for their employees and clients. Our designs followed all local regulations from the City of Tallahassee and Summit East Technology Park. This expansion offers substantial opportunities for Seminole Finances and stability of the park for years to come.
The Human Bean project created an efficient drive-thru coffee shop in Marianna, FL. The shop sat on a small 0.16-acre lot along US Highway 90. This required careful planning to manage traffic flow and make the best use of the limited space. Without good design, congestion could have caused traffic delays and safety issues for customers and passing vehicles.
Florida is grappling with climate change, facing rising sea levels, stronger storms and significant environmental threats. Homeowner insurance premiums average $3,600 yearly, with much of the state’s $145 billion in property at risk from flooding and coastal erosion. Meanwhile, the $15 billion fishing industry is shrinking and saltwater intrusion pollutes drinking water. As climate-related disasters become more frequent, Florida requires advanced infrastructure and precise predictions to mitigate these threats.
We improved the intersection of Old Bainbridge Road and Capital Circle Northwest to enhance safety and accessibility for all users. The original design was dangerous because of its awkward shape, high traffic and poor layout. We fixed these problems by redesigning the intersection. We created a 90-degree angle, added better signs for visibility and improved the drainage system to prevent water buildup.
