TITLE
Recommendation to authorize City Manager to adopt plans and specifications for Invitation to Bid No. PR08023 for the reconstruction of the stream at the El Dorado Nature Center, and award a contract to Mike Bubalo Construction Co., Inc., in an amount not to exceed $700,000. (District 4)
DISCUSSION
Created in 1969, the EI Dorado Nature Center (Nature Center) is a 102-acre public environmental, educational, and recreation center. The Nature Center contains two lakes connected by a stream, which is approximately a half-mile long. During the nearly 40 years that the Nature Center has been in existence, vegetation has grown to shade and clog the stream. Storms have eroded the banks, depositing silt along the stream bottom. Leaves and branches that have fallen into the water have decayed and accumulated on the stream bottom, causing the stream to become shallower. The resulting wider and shallower stream does not provide healthy aquatic or riparian habitat and is eroding into the walking trail.
Restoration plans have been developed for this design-build project. Mike Bubalo Construction Co., Inc., (Bubalo) has provided unit prices for each of the components of the stream restoration, and the exact location of each component will be determined in the field, with close oversight by the City. This will result in a restoration project that is tailored to the specific conditions found at the Nature Center. Because it is not possible to predict the exact conditions that will be encountered and treatments that will be installed, the construction contract is not to exceed $700,000.
The Nature Center stream restoration is being funded by grants under the Safe Neighborhood Parks, Clean Water, Clean Air, and Coastal Protection Bond Acts of 2000 and 2002, and mitigation paid by McDonnell Douglas for violations under the Clean Water Act. Permits for the project have been secured from the California Department of Fish and Game, the Los Angeles Regional Water Quality Cont...
