CASQA membership is open to holders of NPDES stormwater permits; MS4 permittees; construction permittees; industrial permittees; and federal, state and institutional entities. Affiliate Memberships are also available for other stormwater professionals, businesses, trade associations, non-profit groups, etc. that want to participate, but do not hold NPDES stormwater permits. Permit holders are voting members of the organization, and may vote for Board of Directors members, while Affiliate Members and federal, state and institutional entities that do not hold NPDES permits are non-voting members.

CASQA keeps its members up-to-date on the latest information affecting stormwater programs in California through e-mail updates, presentations, web postings, and committee activities. Stormwater permits, programs, and legal challenges make it a rapidly changing field where current information is a must. CASQA holds full day meetings / webcasts throughout the State at least once every quarter with typically over a hundred people in attendance and as many participating by interactive webcast. The meetings include expert presentations from across the state and nation.

In order to add value to CASQA members, the Members-Only section is designed to provide members with services that non-members don't receive online. This includes the ability to submit reviews of pending stormwater quality policies, permits and regulations, and notices of special, non-CASQA meetings and events.  Click here for a "one-sheet" on more of what CASQA is doing for its members.

There are two types of membership:

• Regular membership for NPDES stormwater permit holders
• Affiliate membership for those who want to participate but do not hold NPDES stormwater permits.
