The road will traverse a recharge area
• Most of the proposed roadway East of 34th Street is through a “closed basin” that has no surface outlet.
• The paved 24th Avenue extension will significantly reduce the area where storm water now collects and eventually seeps into the ground.

Areas of flooding with moderate rainfall events

Flooding from Sinkhole Pond after heavy rainfall
CLOSED BASIN...
Any runoff within proposed right of way will have to be stored in a retention basin until the water volume infiltrates into the ground or is lost to evapotranspiration.

In addition to the roadway... retention ponds may be necessary within the NATL
In closed basins water quality entering the Floridan Aquifer is a concern...
