LOWER AMAZON CREED RESTORATION PROJECT <br /> Water Resources Development Act. (WRDA), Section 1135 <br /> Summary of Accomplishments <br /> This is an U.S. Army Corps of Engineers cooperative restoration project with the City of Eugene <br /> as the local sponsor. The BLM is also a cooperating agency because it owns land within the <br /> project: WRDA, section 1135, is designed for the Corps to improve environmental functions, <br /> which were damaged by past Corps' projects. Because the Corps straightened, deepened, and <br /> diverted Amazon Creek in the 1950s and 1960's, this project to remove levees and restore native <br /> wetlands in the Amazon Creek floodplain is a perfect match for this Act. This $6.5 million <br /> project is funded with 75% federal funds (up to $5 million) and 25% local match. This site <br /> provides excellent habitat for water birds, birds of prey, and nesting Western Meadowlarks. <br /> In 1999, the project began on the 400-acre restoration site with the following steps: <br /> 1. About 150,000 cubic yards of levee fill material were removed with: <br /> • 80,000 cubic yards placed at the perimeter of the project to contain the 100-year floodplain <br /> • 70,000 cubic yards transported to Fern Ridge Lake for use in creating dikes to form wildlife <br /> pond habitat for wildlife. <br /> 2. The exposed banks along the channels were protected with over 100-miles of biodegradable <br /> erosion mat materials to stabilize soils and provide a firm base for replanting. <br /> 3. The exposed areas were planted with over 350,000 native plants salvaged from the Fern <br /> Ridge project, and hundreds of pounds of seeds were distributed to restore prairie and <br /> streamside habitats. <br /> 4. Two old weirs at the junction of the Amazon Diversion and "A" Channels were removed, <br /> and a new water control weir was constructed along the "A" Channel near Royal Avenue. <br /> In 2000, the second phase of construction included: <br /> 1. An additiona140-acres of prairie and emergent pond wetland restoration in the floodplain. <br /> 2. Alteration of ditches to create more natural surface flow over the project area. <br /> 3. Monitoring of 1999 restoration. <br /> <br /> 4. A prescribed burn on 27acres. <br /> In 2001, the third phase involved: <br /> <br /> Restoring another 60 acres, with removal of 84,000 cubic yards of material. <br /> Onset of construction of another two miles of the Fern Ridge bike path, including building four <br /> bicycle bridges. <br /> Construction of an observation lookout on Greenhill Road and development of interpretive signs. <br /> Continued monitoring. <br /> <br /> Following completion of the third year, monitoring will continue, and the Wetland Mitigation <br /> Bank will undertake another 138-acres of restoration on adjacent lands owned by BLM within <br /> <br /> the 400-acre site. <br /> <br />
