Detention basins and retention ponds

What is a detention basin?  

A detention basin holds water when it rains and allows the water to completely drain.

What is a retention pond?  

A retention pond is a permanent pool of water that helps improve water quality by treating stormwater runoff. A retention pond holds water all the time. It does not drain within a few days of a rainstorm.

Detention basins and retention ponds must be maintained through maintenance and repairs, as needed. Fences, gazebos, swimming pools and sheds are not allowed to be located in a detention basin or retention pond area.
