A $1047 Pennsylvania Growing Greener grant was given to Delco Anglers and Conservationists for riparian restoration on Darby Creek. Another Growing Greener grant, this one for $68,225, was given to Marple Township for a streambank stabilization project on the creek. Additionally, a $1000 grant from the Pennsylvania Watershed Restoration Assistance Program was given to Delco Anglers and Conservationists for riparian improvement of the creek and several other creeks. In 1997, a $60,000 grant was given to the Darby Creek Valley Association and DelCo Anglers and Conservationists for developing a conservation plan. The grant was provided by the Pennsylvania Department of Conservation and Natural Resources. The Darby Creek Valley Association is an organization whose purpose is to preserve and improve the creek's watershed. It has approximately 100 members.
