Technical Workshop: Green Stormwater Infrastructure Construction Inspection Training
Sunday, March 1, 2026 | 1:00 PM – 5:00 PM
$180.00 ADV | $180.00 ONS
4.0 PDHs
Design of green stormwater infrastructure (GSI) practices are only a part of properly managing stormwater runoff. If the practices are not properly constructed and maintained, they will not function as they are designed. Little guidance has been provided on properly constructing or inspecting the construction of green infrastructure or low impact development (LID) practices. There are many variables, including construction practices and materials, that can have a significant impact on the performance and function of GSI practices. For example, compaction of the subgrade can have a significant impact on infiltration and the overall performance of bioretention areas and permeable pavement. Materials used during construction can also have a significant impact. It is important to have a trained person onsite who can determine if the gravel has been washed and free of fines and if the bioretention soil media contains the amount and quality of organic material as specified in the construction documents. This workshop will discuss the proper phasing of construction, inspection of materials upon delivery, a multitude of proper construction practices, and field testing and verification to ensure GSI practices are properly constructed and function as they are designed.

Technical Workshop: Selection, Design, and Implementation of Filtration Media in Urban Environments
Sunday, March 1, 2026 | 1:00 PM – 5:00 PM
$180.00 ADV | $180.00 ONS
4.0 PDHs
Stormwater practitioners have historically focused on infiltration practices for pollutant removal which use simplified media blends such as sand and compost to meet water quality goals. However, when infiltration is not feasible and pollutants must be treated before discharge to receiving waters, attention to filter media selection, design, and implementation is critical to achieve water quality goals. This presentation will present concepts and tools from the forthcoming ASCE/EWRI publication “Stormwater Filtration Media for the Urban Environment.” Attendees will learn about the Stormwater Infiltration Feasibility Tool (SIFT), the Media Selection Guide (MSG), and media QA/QC along with the proposed blending, delivery, protection, and placement plan (BDPIP). The SIFT tool culminates knowledge and best-use guidance around infiltration and filtration practice applicability to site considerations. The MSG provides summary statistics of treatment performance for bioretention, amended bioretention, high rate biofiltration, sand filters, amended sand filters, and high rate media filters to enable targeted selection of media. The QA/QC and BDPIP summaries include current and proposed methods of testing/verifying media, including the needs throughout the stages from sourcing to confirmation of function. All of these tools when used together can improve the successful implementation of filter media projects. Data gaps and future research opportunities to improve filter media performance will also be presented.

Technical Workshop: Water Quality and Flow Modeling of LID Systems with OpenHydroQual
Sunday, March 1, 2026 | 1:00 PM – 4:00 PM
$160.00 ADV | $160.00 ONS
3.0 PDHs
This workshop introduces participants to OpenHydroQual, an open-source modeling platform for simulating hydraulics and water quality in water infrastructure systems, with a focus on Low Impact Development (LID) practices. Participants will first learn the basic structure and capabilities of OpenHydroQual, including its interface, model components, and simulation framework.
The core of the workshop will involve hands-on demonstrations showing how to create and run models for two or more LID systems—such as bioretention cells, infiltration trenches, or green roofs—within the OpenHydroQual environment. These examples will illustrate how the platform can be used to evaluate both hydraulic performance and pollutant reduction.
In addition, the workshop will showcase GreenInfraIQ (greeninfraiq.com), a web-based tool built on OpenHydroQual that enables users to evaluate the long-term performance of Green Infrastructure practices under varying climate and land use conditions.
The session is designed for both researchers and practitioners interested in LID modeling, water quality assessment, and decision-support tools for sustainable stormwater management.

Technical Workshop: Partnerships & Governance Frameworks for Scaling Up Green Infrastructure
Sunday, March 1, 2026 | 1:00 PM – 4:00 PM
$160.00 ADV | $160.00 ONS
3.0 PDHs
This workshop will focus on governance, partnership, and planning strategies that set the table for scaling up green infrastructure implementation. Participants will examine and discuss case studies on integrating green infrastructure into joint capital planning and maintenance strategies with multiple partners, such as school districts, parks agencies, and streets managers.
The field of green infrastructure for stormwater management has made huge strides by removing barriers to implementation, establishing best practices and standards, and demonstrating success through pilot projects and monitoring studies. After decades of work and growth, many of the technical barriers to scaling up green infrastructure have been removed, while challenges in governance and institutional partnerships remain. Transitioning green infrastructure out of the pilot phase of its evolution and into the business-as-usual category requires practitioners to advance systemic change in the governance and partnership spaces, building upon the technical and regulatory foundations of green infrastructure. Establishing partnering and governance strategies for green infrastructure can increase the rate and scale of implementation, increasing its positive impact on water quality, urban design, ecological function, environmental education, and the many other benefits it can provide to communities.
