Letter from Thomas E. Kucera, UCB lecturer, to Berkeley's Mayor Hancock and city council, re: lack of habitat potential of North Waterfront Park (later Cesar Chavez Park).

Letter from Norman La Force to Loni Hancock, Mayor of Berkeley, November 21, 1993, reiterating Sierra Club's opposition to an off-leash area at North Waterfront Park (later Cesar Chavez Park) and determination to "restore" the landfill to become a habitat and wildlife conservation area.

Creating the Eastshore State Park, An Activist History, Norman La Force, January 1, 2001. La Force wrote that he and others opposed the proposed off-leash area at Cesar Chavez Park because off-leash dogs could harm wildlife, habitat, and small children (page 114). On the next page, he says that "the rise of the dog owner lobby" made inclusion of the CCP landfill in Eastshore State Park increasingly unlikely.

Letter from Norman La Force to City of Berkeley, January 19, 1997, in which he threatens (page 3) to sue Berkeley if it establishes an off-leash dog area at Cesar Chavez Park
