With China Camp and Olompali state parks faced with closure July 1, a local nonprofit group has sent a letter of intent to state officials saying it is willing to operate the parks to keep them open.

The Marin State Parks Association and its subgroups, Friends of China Camp and The Olompali People, want to keep two state parks open in Marin by raising money and developing an operations plan.

The group has raised $100,000 over the past few months. It will need another $240,000 to operate China Camp, while $50,000 will be needed to run Olompali for a year. China Camp is near San Rafael and Olompali north of Novato.

Of California's 278 state parks, 70 are slated to be closed this summer.
