Lake Merced Compensatory Mitigation Project

Why is this project being done?
The Vista Grande – Lake Merced Compensatory Mitigation Project is being implemented to offset future environmental impacts anticipated from the planned Vista Grande Drainage Basin Improvement Project. The City of Daly City and its partners must comply with state and federal regulations (like the Clean Water Act and CEQA) that require mitigation for expected impacts to wetlands and sensitive habitats. By proactively restoring and enhancing habitat at Lake Merced, the City will ensure regulatory compliance once construction of the drainage project begins.

What is the project?
The project focuses on removing invasive plant material and restoring native habitats at 14 designated sites around Lake Merced in San Francisco. It will include:

• Clearing invasive plants (such as eucalyptus).
• Installing protective fencing and Best Management Practices (BMPs) for sediment and erosion control.
• Planting native container plants, live stakes, and transplanting wetland plants.
• Installing irrigation systems to support new vegetation.
• Applying erosion control measures like hydroseeding and mulch.
• Implementing a five-year plant establishment and maintenance period to ensure the success of the restored habitats.

The project also includes requirements for coordination with the City, public safety, traffic and pedestrian management on nearby trails, and compliance with environmental regulations (such as nesting bird protections).

Impact
Environmental Restoration:

• Will enhance biodiversity and support local wildlife around Lake Merced.
• Will create resilient, native plant communities that will thrive in the long term.

Regulatory Compliance:

• Will satisfy compensatory mitigation requirements mandated by permits (e.g., California Department of Fish and Wildlife) tied to the future drainage improvements.

Community Benefit:

• Will enhance the natural beauty and recreational value of Lake Merced for residents and visitors.

Temporary Disruptions:

• Some temporary closures and construction impacts (like fencing, tree removal, and noise) may occur during construction and maintenance activities, but these will be managed to minimize public inconvenience.
