Annual Conference

2018 CASQA Annual Conference

We look forward to seeing you for the 2018 CASQA Annual Conference at the Riverside Convention Center, October 15-17, 2018.

The CASQA Annual Conference offers a unique opportunity to interact with professionals in the stormwater field. Each year the conference draws leading members of the stormwater community including local, state, and federal decision makers, stormwater program coordinators, contractors, consultants, engineers, lawyers, scientists, and planners. Join over 1,000 attendees and 60 exhibitors for 3 days of important training and discussions on the future of our stormwater programs.

Connecting the Drops from Summit to Sea

The 2018 California Stormwater Quality Association (CASQA) Annual Conference will be held in downtown Riverside, the heart of the Inland Empire. This year’s conference theme reflects its location in the upper portion of the Santa Ana River Watershed, an area of diverse habitat and extreme topography. The densely populated watershed is home to over six million people in four southern California counties. Here, as in all of California and beyond, stormwater professionals are hard at work complying with National Pollutant Discharge Elimination System (NPDES) permits and Total Maximum Daily Loads (TMDLs), creating urban infrastructure that implements low impact development and reduces hydromodification impacts, capturing stormwater for water supply, and providing protection for groundwater and surface water resources.

At this year’s conference we will “connect the drops" by providing an extensive program of training workshops, technical presentations, and posters addressing a range of challenges and opportunities facing urban stormwater practitioners including sustainability, source control, conservation, stormwater capture, communication, pollutant management, and permitting. The conference will highlight the recent integrating approaches developed by the State Water Board STORMS Program and the CASQA Vision to establish stormwater as a vital resource through focused efforts and resources.
