Supervisor Simitian, with Board colleague Supervisor Otto Lee, championed a Memorandum of Agreement (MOA) between the County and the Midpeninsula Regional Open Space District (Midpen), to share enforcement of the preservation easement that protects the land adjacent to Rancho San Antonio County Park and Rancho San Antonio Open Space Preserve, effectively reinforcing the protection of local hillsides and habitat for years to come. The MOA grants Midpen the right to monitor and inspect the protected ridgeline and surrounding habitat that is part of the Lehigh Cement Plant & Quarry property. In its 2019 application for an amendment to its existing Reclamation Plan, the Quarry owners had requested the ability to remove material from the ridgeline.
