Biological Construction Monitoring at Cross Creek Road Bridge over Malibu Creek, Los Angeles County - Malibu Coastal Land Conservancy

Rincon Consultants conducted monitoring for biological resources during the construction phase of the Cross Creek Road Bridge located over Malibu Creek. Monitoring was conducted to ensure compliance with the California Coastal Commission Coastal Development Permit, Army Corps of Engineers Section 404 Nationwide Permit, Fish and Game Streambed Alteration Agreement, Regional Water Quality Control Board 401 Certification, and General NPDES Permit for Construction Dewatering. The bridge was funded by a grant from the California Coastal Conservancy to remove an old concrete ford that acted as a barrier to endangered steelhead trout migration. The Malibu Creek corridor is a sensitive habitat due not only to the presence of the steelhead, but also the tidewater gobi in the lagoon, and riparian nesting birds within the willow riparian habitat. The monitoring included pre-construction bird surveys, a pre-construction fish survey/rescue, water quality monitoring/sampling, oversight of construction activities, and agency coordination.
