CASQA 2023 Annual Conference Theme

Rain Ready California: Protecting and Collecting Water for Our Future

The last few years have demonstrated the impact of drought and the changing magnitude and frequency of our precipitation events. Now, more than ever, the work in the stormwater management field is critical to achieving a more resilient future. Collectively, our actions can lead to a Rain Ready California. What does that look like? Investing in our communities to reconnect the hydrologic cycle (e.g., stormwater capture). Rethinking how we work to integrate across water sectors to achieve our shared common goals. Protecting our waterways through true source control and effective BMPs. Engaging within the stormwater profession and the communities we serve to communicate that stormwater is a resource. Advocating for funding, regulations, and legislation to support these outcomes. And most importantly, learning from each other to make it all possible. Let’s get Rain Ready together!

(Pending the abstract selections and final Technical Program)

BMP Effectiveness

This track will focus on advances in BMP performance and in BMP effectiveness assessment methods for treatment control and source control practices. Assessment methods include performance monitoring, benchtop special studies, innovative assessment methods, operation and maintenance practice assessments, challenges, and solutions, and/or lessons learned/case studies.

Climate Change, Resiliency, and Sustainability

This track will look at climate resiliency, sustainable practices, legal requirements and barriers, opportunities for collaboration, and programs that connect stormwater and other environmental sectors. Important topics will be discussed such as climate change adaptation and mitigation, water supply, water rights, groundwater recharge, energy, watershed management, integrating climate resiliency with green stormwater infrastructure, and wildfire planning.

Construction General Permit

This track will focus on the newly adopted 2022 CGP and will include discussions on permit changes and address construction stormwater challenges including: innovative BMPs and controls; TMDL implementation; passive treatment; challenges and solutions to site management; implementing cost controls; resolving monitoring and sampling issues; dealing with the different challenges of linear underground and overhead projects; and other implementation challenges with the newly adopted permit.

Equity and Environmental Justice

This track will focus on the connections between the business of water management and its direct and indirect impact on underserved communities and will include discussions of current programs; lessons learned; and how to bring diversity, equity, and inclusion into all aspects of our work in stormwater communities.


This track will address stormwater program and infrastructure funding and financing, including asset management—both tracking for capitalization and schedule for replacing aging infrastructure, its role in full stormwater program integration, and funding and financing mechanisms that may be available to the regulated community.

Industrial General Permit

This track will cover various aspects of the Industrial General Permit such as pollutant source assessments, monitoring and reporting, Exceedance Response Action requirements, Best Management Practices (BMPs), Total Maximum Daily Loads (TMDLs), water quality based corrective actions, compliance options, permit participation initiatives (e.g., SB 205), and Clean Water Act citizen lawsuits.

Looking Beyond California

This track will focus on advances and practices developed outside of California that California’s stormwater practitioners may benefit from. Examples include water management practices, climate/coastal resiliency examples, scientific advances, or any other stormwater practice relevant to California!

Modeling and Data Tools

This track will focus on modeling of all types, including hydrologic, water quality, and geographic information systems (GIS). Innovative data collection, visualization, assessment tools, and quantification methods and metrics. This track will also include how data tools from other industries may be repurposed for use in the stormwater arena.

Monitoring and Special Studies

This track will highlight innovations in monitoring methodologies or monitoring programs and the development and implementation of special studies such as those investigating pollutant source, fate, and transport, including how monitoring results can be used to inform stormwater management.

Municipal Programs

This track will focus on the challenges and solutions faced while implementing a municipal stormwater program for Phase I and Phase II agencies, The track will also address emerging issues for municipalities such as planning activities for permit compliance, workforce development, operations and maintenance, permanent post-construction BMPs, monitoring program challenges and unique solutions, and transient encampments.

Outreach, Engagement, and Education

This track will share ideas for creating and implementing innovative stormwater outreach projects/programs that are designed to educate the community about stormwater pollution, actions they can take to protect local waterbodies and their watersheds, and the importance of recognizing and utilizing stormwater as a resource. Projects/programs can include efforts such as media campaigns, social media strategies, educational programs for youth, rebate programs, engaging with underserved communities, and measuring the effectiveness of outreach and education activities.

Pollutants of Concern

This track will focus on statewide priority pollutants, in addition to contaminants of emerging concern: what we know or don’t know or need to learn, upcoming regulatory changes that may impact the stormwater community, and new advances in science that allow us to measure or characterize both human and environmental risk related to emerging contaminants. The topics could include trash, PFAS, mercury, pesticides, microplastics, and other constituents of concern.

Regulatory and Legislation

This track will provide a forum for updates from regulators, discussions of future policy and legislative initiatives, newly enacted legislation and its impacts on stormwater, updates from legal experts, and examples and case studies of legislative engagement and innovative ways that regulatory obligations can be met.

Stormwater Capture, Use, Green Infrastructure, and Nature-Based Solutions

This track will highlight examples of physical infrastructure for improving stormwater runoff quality, protecting natural channels from the effects of hydromodification, preventing flood impacts to property, recharging groundwater supplies, permanent post-construction BMPs, and stormwater capture and use. It will focus on planning efforts, pilot studies, design lessons learned, operation and maintenance challenges / solutions, and adaptive management strategies after installation.

True Source Control

This track will incorporate the practice of true source control, and how it relates to stormwater compliance and sustainability. Additionally, examples of how to implement true source control, how to expand true source control in stormwater, and considerations for permit compliance will be addressed.
