Terraphase was engaged to support the City of San Leandro with California Environmental Quality Act (CEQA) environmental compliance for the San Leandro Creek Haas Pedestrian Bridge Debris Removal Project. The project involved the removal of a fallen tree, a damaged pedestrian bridge, and associated debris to reduce flood risk and prevent further damage to the creek before the rainy season.
Scope of Services
Terraphase completed a Notice of Exemption for the project documenting the project scope and justifying exemption eligibility. The proposed work plan included installing a temporary cofferdam 50 feet upstream and downstream of the debris removal area, with a bypass system in place to divert existing water flows; mobilizing an excavator at the end of Cary Drive to pull the fallen tree out of the creek; and selectively demolishing and hauling out bridge debris from a position in the creek. Following debris removal using an excavator, disturbed areas were to be restored with a native seed mix. Terraphase worked closely with the City to ensure environmental considerations were addressed while expediting permitting. The city exempted the project under CEQA Guidelines, Class I Exemption.
Notable Accomplishments
- Supported permitting and environmental documentation for time-sensitive debris removal
- Helped mitigate flood risks by enabling pre-rainy season removal of tree and bridge debris
- Ensured minimal environmental impact through use of cofferdams, bypass systems, and native restoration measures
