The study determined it may be possible to collect urban stormwater runoff within portions of the canal. This water may be able to be passively treated and utilized to support the diverse vegetation, wildlife and other uses along its banks. Most local governments along the canal have expressed interest in participation in a study to develop a model as to how to utilize stormwater as a resource.
