Pulte's lagoon action plan - 3/10/09 update

.
. The approved construction plans call for a minimum 5 ft. depth for all Phase 5 lagoons. DHEC said that they’re going to hold Pulte to the approved construction plans for Phase 5.


DHEC said that the bottom of a pond is that area that encompasses everything except the pond’s 4:1 bank slopes. That is, the entire bottom of the pond should be at the bottom elevation shown in the approved construction plans, i.e., depth = 5 ft. or greater.

As-built drawings show that in 20 of 31 ponds all or some of as-built bottom is at a higher elevation than that shown on the approved construction plans, i.e., depth < 5 ft.

In their 3/10/09 update of the lagoon action plan Pulte failed to address 11 lagoons where all, or some of, the bottom is higher than the bottom elevation shown on the approved construction plans, i.e., depth < 5 ft.

All 20 of the 31 ponds with bottoms higher than the elevations shown on the approved construction plans should be addressed, i.e. should have depths equal to or greater that the 5 ft. called for in the approved construction plans.
