Ordinance No. 90-25-257 Page 3 of 3
ExhibitA
Sec. 24-89. Stormwater, drainage, storage and treatment requirements.
(a) Except as required to meet coastal construction codes as set forth within a valid permit from the
Florida Department of Environmental Protection; or as required to meet applicable flood zone or
stormwater regulations as set forth herein, the elevation or topography of a development or
redevelopment site shall not be altered.
(b) Topography and grading. All lots and development sites shall be constructed and graded in such a
manner so that the stormwater drains to the adjacent street, an existing natural element used to
convey stormwater, or a city drainage structure after meeting onsite storage requirements, as set
forth within this section. The city shall be provided with a pre -construction topographical survey
prior to the issuance of a development permit and a post -construction topographical survey prior to
the issuance of a certificate of occupancy. Elevations in all topographic surveys will be referenced to
NAVD 1988. Said surveys shall be signed and sealed by a licensed Florida surveyor. All new
developments and redevelopments shall provide assurance that adjacent or nearby properties not
owned or controlled by the applicant will not be adversely affected by drainage or flooding.
(c) Onsite storage. Except as provided for herein, an applicant shall be required to provide onsite
storage of stormwater in accordance with this section as follows:
(1)
. . fffaee area enly. The four- hundred (400) square feet of impervious stfffaee area -
Development that results in more than thirty-five percent 35% im ervious lot coverage shall
be required to provide onsite stormwater storage for the entire impervious surface area.
Proiects that result in less than four hundred 400 s uare feet of additional impervious surface
shall be exempt from this requirement, Provided that the total lot coverage remains within the
applicable zoning district. The four hundred (400) square feet shall be calculated cumulatively
from the adoption date of this ordinance.
(2) Any modification or replacement of driveway and sidewalk areas only on a developed lot shall
not be required to provide onsite storage improvements provided the modification or
replacement does not alter the footprint of the existing driveway or sidewalk area.
(3) Applicants shall provide documentations and calculations to demonstrate compliance with
submittal of applications for construction.
(4) Projects permitted by the St. Johns River Water Management District (SJRWMD), which have
an in -compliance existing retention or detention areas that collect and control stormwater are
exempt for further onsite storage requirements; provided, however, a copy of the engineer's
certification of as -built construction to the SJRWMD must be submitted to the city before
building permits for individual lot construction may be issued.
(5) When onsite storage is required, an as -built survey, signed and sealed by a licensed Florida
surveyor, documenting proper construction and required volume of the storage system, must be
submitted to and approved by the director of public works prior to permit closeout or issuance
of a certificate of occupancy. For an under -ground system, a notarized letter from the general
contractor, along with as -built plans and construction photographs will be sufficient to
document proper construction.
(6) In addition, a declaration of restrictive covenant, in recordable form and approved by the city,
identifying and describing the required on-site storage improvements to be maintained, shall be
executed and recorded in the public records of Duval County, Florida, by the owner of the
Exhibit A
development parcel and shall be binding on successors and assigns, prior to permit closeouts or
issuance of a certificate of occupancy.
(7) Volume calculations for any projects that require onsite storage shall be based on the following
calculation:
V = CAR/12, where
V = volume of storage in cubic feet,
A = total impervious area,
R = 25 -year and 24-hour rainfall depth (9.3 inches) over the lot area, and
C = runoff coefficient, which is the difference between impervious area (C=1.0) and undeveloped
conditions (C=0.08).
This volume must be stored at least one (1) foot above the wet season water table and below the
overflow point to offsite (in many cases this may be the adjacent road elevation). As an option, and
as approved by the director of public works, an applicant may implement, at the applicant's cost,
offsite storage and necessary conveyance to control existing flood stages offsite, provided
documentation showing appropriate authorization for the off-site use and meeting the requirements
of this section is submitted and approved by the city.
(d) Floodplain storage. There shall be no net loss of storage for areas in a special flood hazard area
(100 -year floodplain), where a base flood elevation has been defined by the Federal Emergency
Management Agency (FEMA) on flood insurance rate maps (FIRMS). Site grading shall create
storage onsite to mitigate for filling of volume onsite. This storage is in addition to the storage
required for the increase in impervious surface area. The applicant shall provide signed and sealed
engineering plans and calculations documenting that this "no net loss" requirement is met.
(e) Stormwater treatment. For all new development or redevelopment of existing properties, excluding
single- and two-family uses, where construction meets limits for requiring building code upgrades,
stormwater treatment shall be provided for a volume equivalent to either retention or detention with
filtration, of the runoff from the first one (1) inch of rainfall; or as an option, for facilities with a
drainage area of less than one hundred (100) acres, the first one-half ('/z) inch of runoff pursuant to
Chapter 62-330, Florida Administrative Code (FAC). No discharge from any stormwater facility
shall cause or contribute to a violation of water quality standards as provided in Section 62-302,
FAC. This treatment volume can be included as part of the onsite storage requirement in subsection
(b) of this section.
(f) NPDES requirements. All construction activities shall be in conformance with the city's National
Pollutant Discharge Elimination Systems (NPDES) permit, in addition to the requirements of the St.
Johns River Water Management District and the Florida Department of Environmental Protection.
NPDES requirements include use of best management practices (BMPs) prior to discharge into
natural or artificial drainage systems. All construction projects of one (1) acre or more require a
stand-alone NPDES permit. Site clearing, demolition and construction on any size site may not
commence until site inspection and approval of the proper installation of a required best
management practices erosion and sediment control plan is completed.
(g) Enforcement. Subsequent to approval of a property owner's final grading, including onsite and/or
floodplain storage and stormwater treatment and closeout of the applicable permit or issuance of
certificates of occupancy, the improvements shall be maintained by the property owner. In order to
ensure compliance with the provisions of this section and the requirements to maintain onsite
stormwater improvements over time, the city is authorized to conduct inspections of property, upon
reasonable notice and at reasonable times, for the purpose of inspecting said property and/or onsite
storage improvements for compliance with this section and with any applicable conditions of
Exhibit A
previously issued permits. Failure to maintain the improvements will require restoration upon
notification by the director of public works, within a stipulated time frame. If restoration is not
timely completed, the city shall have the right to complete the restoration, and the city's actual cost
incurred, together with a charge of one hundred (100) percent of said costs to cover the city's
administrative expenses, shall be charged to the then owner of the property.
(h) Variances to impervious surface area limits. Variances to impervious surface limits shall be subject
to the provisions in section 24-65. Impervious surface requirements shall not be eligible for relief via
waivers from the city commission.
