meeting:
Jeff Williams stated that the final report would state that the proposed
work would result in a 0.01 foot increase in 100 year flood elevation at
the first foot bridge and a 0.01 foot dec!ease at the confluence of the
main and bypass channels. This increase at the bridge is totally
contained within Dallas County property(the park).
Given a. (above), Ken Griffin indicated that probably the City of Coppell
and FEMA would agree to the proposed Work.
Both Coppell and FEMA will require that any excess excavation be
removed from the site instead of using it to raise the elevation of the
island.
