REFERENCE: LEVEE ENCROACHMENT STANDARDS AND PROCEDURES, <br /> PDR 1130-2-5, 17 March 1980 <br /> 3. SPONSOR: City of Eugene <br /> 4. INSPECTION PARTICIPANTS: <br /> John Todd, Inspector, CENPP-PE-DC, (503) 326-6491 <br /> Richard Zucker, Maintenance Supervisor, (503) 687-5271 <br /> Ruth Koenig, City of Eugene, Environmental Volunteer Program <br /> Brian Elliott, City of Eugene, Maintenance Planning <br /> 5. FINDINGS: The following inspection findings were noted: <br /> a. Clearing of unwanted vegetation from the channel (lined <br /> and unlined) and channel side slopes was noted at various sections <br /> of the project. The City is continuing to conduct clearing <br /> operations from the channel as an ongoing process. The City is <br /> also working with environmental advocates to limit vegetation <br /> removal to only that which is necessary to ensure the channel <br /> capacity is not limited and unwanted vegetation will not result in <br /> backwater. Selective mowing in the channel is recommended between <br /> 29th and 33rd Avenues to ensure adequate velocities during times of <br /> high flow. <br /> b. Sediment deposition noted upstream and downstream of <br /> bridges located at 24th, 29th, 30th, 31st, and 33rd Avenues has <br /> been removed. Slide areas noted at various locations have been <br /> repaired. Removal of berry vines from the right bank of the <br /> channel side slope in the vicinity of the fairgrounds was ongoing <br /> at the time of the inspection. These findings were noted in the <br /> 1993 inspection report. <br /> c. Berry vines were noted on the right bank of the channel <br /> side slope downstream of the fairgrounds and extending to Polk <br /> Street .(approx. 1,000 feet in length) . The vines restrict <br /> inspectw_ of the channel and create habitat for burrowing animals. <br /> d. Minor ruts (2-3 inches deep) were noted on the right bank <br /> access road between Danebo and Terry streets (approximately 1, 000 <br /> feet) . Gravel surfacing should be placed on the road to allow <br /> adequate access for construction equipment during maintenance <br /> operations and during times of flooding. <br /> I <br />
