DRAINAGE CONNECTIONS PERMIT
14-86.001 Purpose.
The purpose of this rule chapter is to regulate and prescribe ensure safe conditions for the transfer of stormwater to and the integrity of the Department of Transportation’s right of way as a result of manmade changes to adjacent properties, through a permitting process designed to ensure the safety and integrity of Department facilities and to prevent an unreasonable burden on lower properties transportation facilities and to prevent an unreasonable burden on lower properties by providing standards and procedures for drainage connections from the properties adjacent to the Department’s right-of-way. All Department actions taken pursuant to this rule chapter shall be in accordance with Section 120, F.S.

The critical duration for a given storm frequency is determined by calculating comparing various durations of the specified storm and 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).

14-86.003 Exceptions Exemption, Permit, and Assurance Requirements.
(1) Exceptions Exemption. The following improvements to adjacent property do not require a drainage connection permit so long as any drainage connection from the adjacent property does not threaten the safety and integrity of the Department of Transportation’s facilities and does not create an unreasonable burden on lower properties, including violations of applicable water quality standards:
(a) All Ssingle-family residential improvements which are not part of a larger common plan of improvement or sale are exempt from the provisions of this Rule Chapter.
(b) All improvements related to Aagriculture and silviculture improvements which are regulated by the Department of Environmental Protection Regulation or regional Wwater Mmanagement Ddistricts or which meet generally accepted engineering practice for drainage and water management are exempt from the provisions of this Rule Chapter.
(c) Any improvement other plan of improvement is presumptively excepted exempt from the requirements to obtain a Drainage Connection Permit provisions of this Rule Chapter provided that all of the following apply are complied with:
1. The total impervious area, after improvement, must be less than 5,000 square feet of cumulative impervious area and is less than 40% of, with a maximum of 5,000 square-feet of buildings and paved surfaces for that portion of the adjacent property that naturally drained to the Department’s right-of-way, provided it is not part of a larger common plan of improvement or sale;
2. The improvement does not create or alter includes no work to be done on the Department’s right-of-way which creates or alters a drainage connection;
3. The improvement does not change flow patterns of stormwater to the Department’s right of way, and does not increase the surface area draining to the Department’s right of way.
4.3. The property is located in a watershed which has a positive outlet.
5. The site or improvement is not part of a larger common plan of improvement or sale.
Any of the foregoing exceptions shall be revoked if any drainage connection from the adjacent property threatens the safety and integrity of the Department of Transportation facilities or creates an unreasonable burden on lower properties, including violations of applicable water quality standards.
(2) Permit. All improvements that are not exempted in subsection Rule 14-86.003(1), F.A.C., require a Ddrainage Cconnection Ppermit, Form 850-040-XX( /07), whether or not the work is done in conjunction with a driveway connection and whether or not the improvement retains stormwater runoff on the adjacent property to and including the 100 year event of critical duration vehicular connection.
(3) Assurance Requirements.
(a) The applicant for a drainage connection permit shall provide reasonable assurances that:
1. The peak discharge rates and/or total volumes of stormwater discharging from the adjacent property to the Department’s right of way are those provided for in an approved stormwater management plan or master drainage plan; otherwise the post-improvement stormwater runoff discharging discharge from the adjacent property to the Department’s right of way under control of the applicant shall not exceed the more stringent of the following:
a. The peak discharge rates and/or total volumes allowed by applicable local regulation; or
b. The improvement pre-improvement peak stormwater runoff discharge rates shall not increase stormwater discharge be increased, and in addition in watersheds which do not have a positive outlet, the post-improvement stormwater runoff total volumes shall not be increased above the pre-improvement condition, and in watersheds which do not have a positive outlet, the post-improvement total volume of stormwater runoff shall not be increased considering worst case storms for up to the frequencies and durations contained in paragraph 14-86.003(3)(c), F.A.C.
2. Any discharge pipe establishing or constituting a drainage connection to the Department’s right of way shall be limited in size based on the pre-improvement discharge rate, downstream conveyance limitations, and downstream tailwater influences. The applicant’s stormwater runoff discharge coming to the Department’s facility through the created features of the drainage connection may not exceed its prorata share allowed by either the design capacity of the Department’s facility or by other governmental entities.
3. If the improvement changes the inflow pattern of stormwater or method of drainage connection to the Department’s right of way, the applicant shall demonstrate that post-improvement discharge will not exceed the pre-improvement discharge to the Department’s right of way and that any new drainage connection does not threaten the safety or integrity of the Department’s right of way and does not unreasonably increase maintenance costs to the Department. This demonstration shall at a minimum include analyzing pavement hydraulics, ditch hydraulics, storm drain hydraulics, cross drain hydraulics, and stormwater management facilities. The analysis must follow the methodology used in the design of the Department’s facilities receiving the discharge and meet the criteria in the Department’s Drainage Manual, Topic Number 625-040-002-c, January 2008, incorporated herein by reference. The Drainage Manual is available on from the Department at: http://www.dot.state.fl.us/rddesign/dr/Manualsandhandbooks.htm.
4.3. The quality of water conveyed by the connection meets all applicable water quality standards or minimum design and performance standards, and such assurance shall be certified in writing. In the event the discharge is identified causing or contributing to a violation of applicable water quality standards, the permittee will be required to incorporate such abatement as necessary to bring the permittee’s discharge into compliance with applicable standards.
(b) If the requirements set forth in paragraph Rule 14-86.003(3)(a), F.A.C., cannot reasonably be fully complied with, the applicant may submit alternative drainage connection designs which will require the approval of the District Secretary. The analysis supporting the proposed alternative connection must follow the methodology used in the design of the Department’s facilities receiving the proposed alternative drainage connection and meet the criteria of the Department’s Drainage Manual. Acceptance of any alternative designs must serve shall be based upon maximum achievement of the purpose of this rule chapter and shall be based upon consideration of the following:
1. The type of stormwater management practice proposed;
2. The probable efficacy and costs of alternative controls;
3. The impact upon the operation and maintenance of the Department’s facilities facility; and
4. The public interest served by the drainage connection.
(c) In providing reasonable assurances, the applicant shall:
1. Use a methodology which is compatible with the methodology employed used in the design of the Department’s facilities receiving the stormwater facility; and
2. Determine the peak stormwater runoff discharge rates considering various rainfall event frequencies up to and including a 100 year event of critical duration of up to three days; and
3. In watersheds without a positive outlet, determine the stormwater runoff total volumes considering various rainfall amounts up to a 100 year rainfall frequency of critical durations of up to ten days. The retention volume required to comply with this rule must meet the pond recovery criteria in the Department’s Drainage Manual.
