Our senior design project improves the water treatment system at Camp Weed and Cerveny Conference Center located in Live Oak, Florida. The retreat center’s primary function is hosting summer camps. During the summer, the large number of campers increases the scale of the water demand, which varies throughout the year. This out-of-date system needs new hardware, a new system order, and a new storage tank to meet the camp’s needs. Our design uses different chemicals (H2O2 and Cl) to produce clean water while meeting the camp’s water requirements. Using the average daily consumption during peak times and the calculated amounts of chemicals, we will provide the necessary clean water to Camp Weed. The old, existing water tank will soon be out of service, and a new tank will replace the water supply stored in the old tank. The design follows all laws and guidelines developed by the FDEP, AWWA, ASTM, and EPA. Though the focus of our design is on the improvement of the current water treatment system, other designs are a part of our plans. We prepared concrete footing pads, steel supports, and soil analysis. These together will create clean water for the people of Camp Weed and the Cerveny Conference Center.

Our project is to reconstruct an intersection along Florida’s State Road 75. The intersection is located in Jackson County, FL, where Jacob Road intersects State Route 75. Florida Department of Transportation (FDOT) requested a redesign of this intersection due to an abnormally high number of car accidents. Most of these accidents are classified as angle-related. They are caused by Jacob Road users being struck as they cross State Route 75. We were asked to increase the safety of the road and reduce the number of crashes with our redesign and to extend the life of the road by 20 years.
We chose to implement an Unsignalized Restricted Crossing U-Turn (RCUT) at the intersection to increase road safety. This redesign restricts Jacob Road users from crossing straight through the intersection. Instead, it redirects them to turn right, where they travel a short distance before making a U-turn onto the other side of the road. We created our R-CUT using multiple references provided by the FDOT. We produced drawings and plans, pavement design, drainage calculations, and typical roadway section details for the new intersection. Along with the plans for the intersection, we provided a budget and sample construction schedule. The final plans follow FDOT regulations while keeping safety, traffic patterns and project cost optimum.

The Thomas P. Smith Water Reclamation facility faced efficiency and load capacity problems at its waste treatment plant. We designed an equalization tank to fix it. The current storage tank at the facility reached capacity at three and a half days, with 17 million gallons. The nutrient-rich sludge that undergoes treatment at the waste facility caused a strain on the pipes within the system—the load would become too heavy at the end of a three-day cycle. To mitigate this, we designed a centrate equalization tank with a capacity of 31 million gallons and a flow system that operated for six and a half days. The goal in implementing the centrate tank is to regulate the impact of the nutrient-rich liquid on the system and increase the facility’s storage capacity to further the lifespan of the plant. The new centrate tank was designed to be located adjacent to the Centrifuge Dewatering Facility at the plant. We considered essential constraints including odor emissions, material sizing, permitting and environmental safety factors.
The project scope aimed to design a sustainable centrate equalization tank with a steady flow that transported the liquid filtrate back to the front of the water reclamation facility. Drawings were instrumental in implementing our design, mass balance and hydraulic flow calculations were completed to ensure full functionality of the tank and treatment system.

Apalachee Regional Park is located off Apalachee Parkway in Tallahassee, FL. The park is home to the NCAA Cross Country championship competitions, football fields, a city waste center and a drone field. It is the center of interest in the tourism strategy to bring in more money for Leon County Parks and Recreation. However, the park needs a few upgrades to bring a more vibrant and welcoming feel to the landmark.
After analyzing the existing entrance to the park, we designed a roundabout that considers existing ditches, trees, a sealed landfill and parking lots for sporting clubs at the park. We provided the design decisions for roundabout size and location, determined the drainage impacts, erosion control, and protected existing features. We created a demolition and tree removal plan.
Our plan proposes ridding the site of the existing poor-quality asphalt intersection and replacing the four-way stop with a high-quality roundabout. We will cut down and remove any interfering plant life. The pre-existing devices and power lines will be capped and/or shut off until construction is completed. Removed trees will be replanted in the center island of our roundabout. Manhole covers will cover the devices for easy access for future inspections.
Upon completion, the roundabout will be the ideal entrance, allowing tourists access to all parts of the park and will protect the park’s existing drainage and amenities. It will also provide a visually appealing entrance to Apalachee Park.

Creating FAMU Way: Phase IV continues the existing roadway to S. Monroe St. and replaces a current signalized intersection with a roundabout. The hardest part of this project was deciding the best route and optimum width of Right of Way (R.O.W). All possible routes have detrimental impacts on existing developed properties loved by the Tallahassee community, especially Shell’s Restaurant and the True Fellowship of Holiness Church. If a narrower R.O.W. is used to keep the buildings intact, the roundabout will not meet the specifications turning design speed and turning radius. A narrower R.O.W. also limits pedestrian and landscape features incorporated in the previous phases of the roadway. We created an alternative design matrix to judge two project alternatives. Both choices were almost the same when using a weighted-point system, so the higher-scoring alternative was selected.
Using the alternative design matrix and the specifications detailed in the scope of work, we decided that the best solution was to go with the full-width R.O.W.
A new roundabout in place of the existing signalized intersection will help increase traffic flow while keeping the current level of service. The new design is pedestrian-friendly and will align pedestrian traffic throughout the new road and roundabout. The new roundabout and signalized crossing will continue to display a nice area that has been provided in the city’s infrastructure and throughout the connection of FAMU Way to the community.
