Florida Administrative Code › 14 - DEPARTMENT OF TRANSPORTATION › 14 - Departmental › Chapter 14-86 - DRAINAGE CONNECTIONS › Section 14-86.002 - Definitions

Current through Reg. 50, No. 138; July 16, 2024
As used in this rule chapter the following terms shall have
				  the following meanings:
(1) "Adjacent
				Property" means any real property or easement with a shared boundary to the
				Department's right-of-way.
(2)
				"Applicant" means the owner of adjacent property or the owner's authorized
				representative.
(3) "Applicable
				Water Quality Standards" means rules and regulations of state or federal
				governmental entity(ies) pertaining to stormwater discharges from the
				Department's facilities to which the drainage connection is made.
(4) "Critical Duration" means the length of
				time of a specific storm frequency which creates the largest volume or highest
				rate of net stormwater runoff (post-improvement runoff less pre-improvement
				runoff) for typical durations up through and including the 10-day duration for
				closed basins, i.e. without a positive outlet, and up through the 3-day
				duration for basins with positive outlets. The critical duration for a given
				storm frequency is determined by calculating the peak rate and volume of
				stormwater runoff for various storm durations and then comparing the
				pre-improvement and post-improvement conditions for each of the storm
				durations. The duration resulting in the highest peak rate or largest net total
				stormwater volume is the "critical duration" storm (volume is not applicable
				for basins with positive outlets).
(5) "Department" means the Florida Department
				of Transportation.
(6) "Discharge"
				means the event or result of stormwater draining or otherwise transferring from
				one property to another or into surface waters.
(7) "Drainage Connection" means any
				structure, pipe, culvert, device, paved or unpaved area, swale, ditch, canal,
				or other appurtenance or feature, whether naturally occurring or created, which
				is used or functions as a link to convey stormwater.
(8) "Facility" or "Facilities" means anything
				built, installed, or maintained by the Department within the Department's
				right-of-way.
(9) "Impervious Area"
				means surfaces which do not allow, or minimally allow, the penetration of
				water. Examples of impervious areas are building roofs, all concrete and
				asphalt pavements, compacted traffic-bearing areas such as limerock roadways,
				lakes, retention/detention areas, pond liners, and other standing water
				areas.
(10) "Improvement" means any
				man-made change(s) to adjacent property which establishes or alters the rate,
				volume, or quality of stormwater.
(11) "Licensed Professional" means an
				individual licensed under chapter 471, F.S., authorized by law to design and
				certify the stormwater management system under review.
(12) "Permit" or "Drainage Connection Permit"
				means an authorization to establish or alter a drainage connection to the
				Department's right-of-way issued pursuant to this rule chapter.
(13) "Permittee" means the individual or
				entity to which a Drainage Connection Permit is issued.
(14) "Positive Outlet" means a point of
				stormwater runoff into surface waters which under normal conditions would drain
				by gravity through surface waters ultimately to the Gulf of Mexico, the
				Atlantic Ocean, or into sinks, closed lakes, or recharge wells provided the
				receiving waterbody has been identified by the appropriate Water Management
				District as functioning as if it recovered from runoff by means other than
				transpiration, evaporation, percolation, or infiltration.
(15) "Post-improvement" means the condition
				of property after improvement.
(16)
				"Pre-improvement" means the condition of property:
(a) Before November 12, 1986; or
(b) On or after November 12, 1986, with
				connections which have been permitted under this rule chapter or permitted by
				another governmental entity based on stormwater management requirements equal
				to or more stringent than those in this rule chapter.
