From the California Stormwater Quality Association Website:

If you attend only one stormwater conference in 2015, this is the one! The CASQA Annual Conference offers a full agenda of stormwater focused training workshops, presentations, and exhibits, as well as 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. This year the popular Monday evening Networking Event will be held at the Monterey Bay Aquarium.

Stop by the Campbell Scientific booth, #40.
