Document Description
Alter the stream to remediate the diversion of the stream through a sinkhole into a tunnel being dug beneath the stream as part of the Black Mountain Road Pipelines Project. The remediation project involves diverting the stream by blocking the flow just upstream of culverts associated with an existing crossing, pumping the pooled water to a desilting area downstream of the sinkhole and returning it to Los Penasquitos Creek, then pumping the water in the sinkhole will be clocked to prevent water from back-flowing into the site. Once the water is diverted, a pumper truck will be set up on Black Mountain Road and will pump a slurry mix into the sinkhole to stabilize the tunnel. Any water containing slurry will be pumped back into the tunnel or into an existing desilting tank to settle. Native riparian habitats found on site include: southern willow scrub, freshwater marsh, and open water.
