The area is an environmentally sensitive area, thus a great deal of perimeter orange boundary fencing was installed around the project work areas to keep the workers inside the restricted work zone so the native vegetation was not disturbed. This was very successful and we experienced no intrusion or damage to the native vegetation. Additionally our SWPPP program was substantial both during and post construction to avoid deteriorating the native soils and to avoid any silt run off that could occur during rain events.

There we two concerns regarding the mating seasons of protected birds, the Gnat Catcher and the Least Bell’s Vireo. A monitoring program was put in to affect to determine if the Gnat Catcher was nesting with the potential to mate in the area. The monitoring took place for 3 weeks prior to the mating season to determine if the species was beginning to nest in the area. None were found adjacent to our work zone during the first phase of work. For the Least Bell’s Vireo this was a different scenario. Construction could not intrude within 300 feet of the potential nesting area for this bird, monitoring was not an option  to determine if the birds were in this area for potential mating, it was  expected they were or needed to be allowed to nest at any given time.
