Introducing CMAC to Engineers Without Borders

Thank you to everyone who joined us for the most recent enlightening presentation on Continuous Monitoring & Adaptive Control (CMAC) technology! On April 8th, 2024, NST and Florida State University’s Engineers Without Borders collaborated to deliver an insightful session led by NST’s Jackson Ledford, P.E.

Jackson described the innovative realm of CMAC technology, which is revolutionizing stormwater management practices. Here are some highlights from the presentation:
• Introduction to CMAC Systems: Attendees gained a comprehensive overview of how technology is changing the landscape of stormwater management.
• Reshaping Pond Maintenance with Technology: Jackson delved into how technological advancements are transforming the maintenance of ponds, offering more efficient and effective solutions to water quality and flood control.
• Case Studies: Attendees had the opportunity to explore case studies comparing conventional ponds to Smart Ponds, providing real-world examples of the benefits of this technology.

37th Annual Environmental Permitting Summer School Recap

This year’s event in Marco Island was a resounding success, with participants gaining valuable insights into cutting-edge environmental solutions. 

In particular, we’d like to highlight the remarkable presentations by Mark Thomasson and Jack Fiveash, which delved into the fascinating realms of “Stormwater Nutrient Credit Trading, Smart Ponds and Resilience in Florida.”

Water Quality Credit Trading

Mark Thomasson served on a panel of experts that examined some recent examples of innovative nutrient trading, evaluated the legislation filed in 2022, and discussed some new approaches to managing nutrients in impaired watersheds. 

Mark took attendees on a journey into the world of “Smart Ponds” and how they are revolutionizing water quality management with the stormwater nutrient credit market in Florida.

He shed light on how the integration of sensors, data analytics, and real-time monitoring can transform these ponds into intelligent systems. These “Smart Ponds” can autonomously adjust water levels, optimize treatment capacity, and their operation to achieve maximum effectiveness.
