Sustaining Members make an ongoing monthly contribution to Riverwalk Fort Lauderdale which is easier and more efficient. Your membership benefits begin on day one. These secure, automatic monthly payments from your credit or debit card means we will deduct your designated contribution from your account each month until you tell us to stop or change it. Less paper, postage and administration costs means more of your membership will go towards the programs and services that help us to make Downtown Fort Lauderdale a vibrant and beautiful place for residents, businesses and visitors alike.
