The San Francisco Forest Alliance has filed an appeal with the Board of Supervisors, saying that many of the claims in the comprehensive new plan are unsubstantiated and too far-reaching. It will be heard Feb. 28 at the board’s regular Tuesday meeting.

“The environmental impact review must be adequate, accurate and objectively analyzed in order for its certification to be legal,” the Forest Alliance said in a release.”

The conclusion: “If the nonprofit — which fights perceived threats to public parks — is successful, the plan’s environmental impact review will be sent back to the city’s Planning Department for further review.”
