Effective today, 5/28/26 you may exchange your existing key cards (with the blue Rio Alto label) or purchase a new one if you do not already have one, at the District Office. Existing customers do not need to complete a new application, just come to the office, turn in your old key car and receive a new one. New cards will have a black Rio Alto label. We will leave the wetlands open to all until June 26th, when only new key cards will be able to access the wetlands. Thank you so much for your patience during this transition.
