ALAMEDA -- City workers and the state Coastal Conservancy will begin work Monday to help eradicate the invasive weed Spartina from along the shoreline.

Public paths will remain open during the work, which will continue through Thursday and aims to prevent flooding and promote the overall health of the tidal zones along San Francisco Bay.

The removal will take place along the 2400 block of Shoreline Drive; Bayview Drive to Towata Park; Bay Farm Island Bridge to the High Street Bridge; and at Bay Farm Island Shoreline Park from Veterans Court to Brunswick Road.

While walking and bicycle paths will remain open during the project, the Public Works Department is still asking people to stay away from areas where the weed is being removed since crews will be using a non-toxic herbicide.

This marks the ninth year that the city and Coastal Conservancy have partnered to remove Spartina from the shoreline.

Also known as cordgrass, Spartina is a highly invasive plant that can significantly alters both the physical structure and biological composition of tidal marshes, mud flats and creeks.

Since the removal project began in 2005, shoreline areas covered by Spartina have been reduced by approximately 90 percent, according to city officials.

Work to reduce the weed in areas around Ballena Bay will take place in October.

Notifications of pending work at specific locations will be posted approximately 48-72 hours in advance.
