While geocells have been commercially available for 40 years, they are under-utilized when attempting to vegetate challenging slopes. Using three-dimensional geocells in these applications allows you to confine up to 12" of topsoil, preventing it from eroding and giving ample long-term organic material for long-term vegetation establishment. I will begin with an introduction to slope failure mechanisms and how each are caused. I will then introduce geocells, including their history, the different cell sizes and cell depths that are available and when each variation is suitable for use. Next, I will discuss the various accessories that go along with the geocell, including connection devices, various anchoring options and when each is recommended. I will finish the presentation highlighting various case studies of vegetated geocell slope protection, including showcasing the installation processes using the various anchoring options.

To provide watershed managers, municipalities, and restoration practitioners with a new operational approach to HAB prevention by identifying where and how to interrupt the hypoxia cascade. The presentation demonstrates how Nature-based Solutions (NbS) deployed across a corridor — rather than isolated lake treatments — can reduce nutrient mobility, stabilize oxygen, and prevent bloom conditions before they develop. Hypoxia is not a localized water-quality issue — it is the unseen engine that drives harmful algal bloom formation across entire watersheds. When oxygen drops in one zone, internal phosphorus release accelerates, microbial communities shift, organic carbon increases, and downstream waters inherit amplified bloom conditions. This presentation demonstrates why managing HABs requires interrupting the hypoxia cascade at its earliest points — upstream, at depth, and at key control structures — rather than relying on in-lake, end-stage treatments. By applying corridor-scale, Nature-based Solutions, we can stabilize oxygen levels, bind nutrients, and restore system function long before a bloom takes hold.

This session will explore the practical benefits and technical details of small-footprint, mobile inclined-plate settling tanks (Lamella Clarifiers) in major earthworks projects across New Zealand. We'll address the challenges posed by NZ's remote and hilly terrain, and demonstrate how these tanks can enhance time, cost, performance and reporting efficiency during rain events, especially when discharging to sensitive natural waterways. Using the post-cyclone Gabrielle recovery and repair of Brynderwyn Hill on SH1 (NZ's main highway) as a case study, we'll fill knowledge gaps regarding the mobility, performance, and deployment of these tanks in adverse weather conditions.

Large rocks and seawalls are typically used in coastal applications to protect shorelines and prevent erosion. These solutions appear to be strong on the surface given their size and weight, but they can promote erosion in certain scenarios and disrupt the marine environment. The presentation is intended to provide information about living shorelines and the benefits they offer over traditional gray infrastructure solutions.

Determination of appropriate stormwater discharge monitoring points is a fundamental component of an effective process for managing stormwater and temporary erosion and sediment control in compliance with project-issued Section 402 Construction Stormwater General Permit Conditions. Permit wording can be general and challenging to interpret.

Permeable Articulating Concrete Blocks (P-ACB) offers advantage over interlocking concrete pavers as permeable pavements. By leaving joints open, these systems have substantially elevated surface infiltration rates and simplified maintenance processes, including a 6-year no maintenance warranty. Because P-ACB systems use thicker blocks that interlock, the surfaces can be HS-20 rated for heavy traffic-- expanding the design possibilities. From a stormwater management and maintenance perspective it is possible to monitor the water level in the base and document performance and optimize maintenance schedule. These systems show significantly elevated performance on clay soils and during high-intensity rainfall events.

Historically limited by scalability and reliability issues, chitosan-based biocoagulants are now a robust solution, made possible through advanced formulations and rigorous U.S. based manufacturing standards. With the highest rating under the EPA's Safer Choice certification, chitosan presents a non-toxic, highly effective option that consistently performs in diverse stormwater systems, providing a green pathway to reduce pollutants and protect aquatic ecosystems. This interactive presentation will dive deep into a case study involving a meat packaging facility in Georgia where stormwater is also being treated int he same system. Chitosan-based biocoagulants replaced aluminum and caustic chemicals in their onsite activated sludge wastewater treatment facility.
