Att-9 Project Construction Plans.pdf

These are 65% design submittal construction plans for the Madonna Creek Dam Repairs project, prepared by Waterways Consulting for what appears to be an open space preserve district in San Mateo County, California. The document set includes site location maps, existing conditions overview, site plans, centerline profiles, and detailed fence and site boundary drawings. The plans show a comprehensive repair strategy involving slope stabilization, earthwork, and site preparation, with multiple layers of engineering interventions including rock slope protection, compacted earth fill, and carefully specified ground treatment using different classes of cementitious materials and geotechnical approaches.

The project documents indicate this is part of a broader biological services procurement process, with a Request for Qualifications (RFPQ) issued for professional biological services related to the dam repair. The project timeline includes key dates such as the RFPQ issuance on 4/17/25, proposal submission deadline of 5/23/25, district ranking on 5/29/25, potential firm interviews on 6/2/25, and Board of Directors contract approval scheduled for 7/9/25. The repair appears to be located at Miramontes Ridge Open Space Preserve, with the design focusing on comprehensive dam infrastructure rehabilitation and environmental site restoration.
