New Erosion at Landfills 8 and 10
Large Erosional Gully at Landfill 8 (click photo to enlarge)
Earlier this week, a series of big storms from the ongoing El Nino weather pattern created major problems for two Presidio remediation sites. These new concerns are indeed alarming given the disturbing trends identified by concerned citizens on January 11, 2010 to the Trust Board of Directors.
At Landfill 8, a large erosional gully formed and channeled huge amounts of cover material and debris well off the site. The Department of Toxic Substances Control issued this emergency letter on January 21st, 2010 requiring the Trust to act. At Landfill 10, the parking area for the Public Health Services hospital, there has been major erosion on the slope, sending tons of cover material mixed with debris into native habitat and severely damaging the landfill cover.
Presidio neighbors living at the 15th Avenue Gate adjacent to Landfill 10 have been plagued by flooding as the new construction and rains combined.

Most frustrating. Back in November I had a conversation with one of the project managers who indicated they were “caught by surpise” when the November storm damaged the retaining provisions and heavily silted the creek. According to him at the time they were taking new measures including installing a collection tank. The sandbag and tank approach does not seem to be viable, and some type of additional drainage tied into the parking lot system seems needed. There are many more issues with this remediation than meet the eye and neighbors attention
