This is a potential wildlife attractant. CORRECTIVE ACTIONS: Provide an estimate as to how long this condition may persist and a proposed means to address/mitigate the problem by the Corrective Action due date. CORRECTIVE ACTION DUE DATE: 9/16/15 RESPONSE: CC&V anticipates eliminating the pool by mid November. Our proposed contingency plan, regarding wildlife, is that if there are observations of wildlife in the vicinity of the pooled area, CC&V will provide temporary fencing along the PSSA perimeter in the pooled area. Currently, a ramp to the water exists which would allow for wildlife to exit the pool. #4 INSPECTION TOPIC: Support Facilities Not On-site PROBLEM/POSSIBLE VIOLATION: Problem: The observed ponded water in the SGVLF PSSA may pose geotechnical slope instability problems that may lead to sloughing on the certified and approved PSSA liner.
