DETENTION STORAGE
The temporary detaining or storage of stormwater in reservoirs,
on rooftops, on parking lots and other areas under pre-determined
and controlled conditions.
DEVELOPMENT

than that volume and rate that pertained prior to proposed development
or redevelopment.
DRAINAGE PERMIT

assigned, upon approval of a final stormwater management plan.
EASEMENT

are shown on the floodway maps filed at City Hall.
RETENTION BASIN
A manmade area which serves as permanent storage of stormwater

surface.
STRUCTURE
Any object constructed above or below ground.
TRIBUTARY AREA

point.
WATERCOURSE
