About this file
The provided document is a PDF file containing site photographs for the Madonna Creek Dam Repair Project, issued by the Midpeninsula Regional Open Space District in California. The images document the dam's condition before and after winter storm damage in 2022/2023, showing significant erosion and slope damage caused by a clogged spillway that led to dam overtopping. The project scope involves repairing and stabilizing the dam's downslope embankment through engineered fill, rock slope protection, and native vegetation restoration. The project is scheduled for bid opening on 6/10/25, with contract award anticipated on 7/9/25, on-site activities commencing 8/18/25, and work completion targeted for 10/31/25.
The photographs illustrate the extensive damage to the dam, with before (2020) images showing a relatively intact slope with rock armoring, and after (2023) images revealing significant erosion, exposed earth, and a dramatically altered landscape. The project will be competitively bid, with a mandatory pre-bid tour and specific timelines for questions, addenda, and bid submissions. The repair work will take place at the District's administrative location in Los Altos, California, with the total project budget and specific funding sources not detailed in the provided documentation.
