It’s been three months since a plan was approved to overhaul the bullet-riddled Sharp Park Rifle Range, and construction could start soon.

The Recreation and Park Commission is scheduled to vote Thursday on a contract to start excavating about 15,000 cubic yards of soil contaiminated with lead shot at the range.

The range was closed in 1988 after bullets were discovered in a nearby residential area, according to DTSC which is overseeing the soil removal action plan.

The removal was initially supposed to start a couple years ago, but the former project manager with the DTSC said he thinks an endangered species issue postponed it for a while.

In 1917, Sam Murphey and Jenny Murphey, donated 450 acres to the City and County of San Francisco with a deed restricting it to recreational land use, and The City made it into the six-acre rifle range site and the Sharp Park Golf Course, according to the state Department of Toxic Substance Control.
