The project was funded utilizing the Hazard Mitigation Grant Program and <br />Canadian County personnel and equipment. Design and construction inspection was provided by <br />a local engineer as part of the local participation requirement. Local landowners provided utility <br />relocation and borrow material. The project was designed to provid,e ingress and egress during <br />the 100-year storm event, not available prior to construction, and provides additional floodwater <br />protection to a major collector roadway approximately 2 miles downstream. <br /> <br />f <br />L <br /> <br />Cecil R.
