ORDINANCE NO. 13B-2014
AN ORDINANCE TO AMEND THE CODE OF ORDINANCES
PERTAINING TO SECTION 3-080(C)(5) REGARDING
OFF-STREET PARKING REQUIREMENTS
FOR THE CITY OF TYBEE ISLAND, GEORGIA
WHEREAS, the duly elected governing authority for the City of Tybee Island, Georgia,
is authorized under Article 9, Section 2, Paragraph 3 of the Constitution of the State of Georgia
to adopt reasonable ordinances to protect and improve the public health, safety, and welfare of
the citizens of Tybee Island, Georgia, and
WHEREAS, the duly elected governing authority for the City of Tybee Island, Georgia,
is the Mayor and Council thereof, and
WHEREAS, the governing authority desires to adopt ordinances under its police, zoning,
and home rule powers, and
WHEREAS, the City of Tybee Island so as to amend Section 3-080(C)(5), Off-street
parking requirements, so as to clarify its terms; and
NOW, THEREFORE, it is hereby ordained by the governing authority of the City
of Tybee Island that Section 3-080(C)(5) of the Code of Ordinances of the City of Tybee Island
shall be amended.
SECTION 1
Section 3-080(C)(5), shall be amended so that hereafter it will read as follows:
Sec. 3-080. - Off-street parking requirements.
(C)(5) For water quality purposes, all newly constructed driveways and replacements of more than
50 percent of existing driveways serving residential uses shall be constructed of materials
designed to allow retention of the first one-inch of stormwater. A new driveway includes the
initial placement of any material on bare soil. Such new driveways and replacements of more
than 50% of an existing driveway are subject to permitting and inspection(s). A permit and
inspection(s) are also required for repair of less than 50% of an improved driveway. The
retention requirement is based on a 24-hour, 25-year Tybee Ill SCS storm. A permit is required
for installation of a new or replacement driveway. An inspection is required of each layer prior to
the next layer being installed. The permit applicant shall be responsible for all engineering fees
incurred by the city for review of materials, even when a material is not approved. Acceptable
materials include:
a. Stone must be either AASHTO #57, #67, #78, or #89 open graded with no fines, or
pea gravel with no fines, or a combination of two or more. Graded aggregate base (also
known as "crusher run" or"crush and run") is not allowed.
b. Standard brick pavers are 4-inch by 8-inch with minimum 5/64-inch average
continuous joints/borders with eight 1/8-inch wide spacers per paver filled with masonry
sand. See item (c) for base and header requirements. If larger bricks are used, thereby
creating less linear joint and surface area joint, calculations by a Georgia licensed design
professional must be reviewed and approved by the city. See engineering fee information in
paragraph 1.
c. Permeable interlocking concrete pavers (PICP) are solid structural units installed
with openings as described in the Coastal Stormwater Supplement (CSS) through which
stormwater runoff can rapidly pass into the underlying reservoir of a 4-inch minimum depth
open-graded stone, no fines. Openings may be filled only with pea gravel or larger stone, or
with masonry sand. A concrete header curb or paver/concrete block ribbon with a maximum
width of 8-inches must be installed around the perimeter of the pavers. Building foundations
and garage floors may serve as a portion of the perimeter. The edge of a paved road may
not serve as a perimeter. Flush headers and ribbons are included in the driveway
measurements. To not be included in the driveway measurements a header or ribbon must
be installed lower than the driveway pavers, covered with adequate top soil, and seeded or
sodded to facilitate vegetation.
d. Ribbon driveway designs are normally constructed of concrete but other materials
may be considered. The ribbons are to be a maximum of 18-inches wide with a 1%-2%
cross slope to route runoff to adjacent pervious areas rather than down the strips to the
street. The area between the strips may be either grass or stone as described in item (a).
The area between the drive strips is to be flush or 1/8-inch below the driving strip to
encourage the percolation of stormwater runoff between the driving strips.
e. Concrete grid pavers (CGP) are precast concrete units that allow rainfall and
stormwater runoff to pass through large openings that are filled with pea gravel, sand or
topsoil and turf. A concrete header curb or brick/concrete block ribbon with a maximum
width of 12-inches (flush or 1/8-inch higher than the contained permeable pavement) must
be installed around the perimeter of the permeable pavement. Building foundations and
garage floors may serve as a portion of the perimeter. The edge of a paved road may not
serve as a perimeter. Header and ribbons are included in the driveway measurements. To
not be included in the driveway measurements a header or ribbon must be installed lower
than the driveway pavers, covered with adequate top soil, and seeded or sodded to facilitate
vegetation.
f. Plastic grid pavers (PGP) consist of flexible, interlocking plastic units that allow
rainfall and stormwater runoff to pass through large openings that are filled with gravel, sand
or topsoil and turf. A header curb is required and is included in the driveway measurement.
g. Pervious concrete (also known as porous concrete) is similar to conventional
concrete in structure and form, but consists of a special open-graded surface course,
typically 4-to 8-inches thick, that is bound together with portland cement.
h. Porous asphalt is similar to pervious concrete, and consists of a special open-
graded surface course bound together by asphalt cement.
For all other proposed materials, calculations are required from a Georgia licensed design
professional demonstrating compliance with the retention requirement of this ordinance.
SECTION 2
The sections, paragraphs, sentences, clauses and phrases of this ordinance are severable
and, if any phrase, clause, sentence, paragraph, or section of this ordinance shall be declared
illegal or invalid by the valid judgment or decree of any court of competent jurisdiction, such
illegality shall not affect any of the remaining phrases, clauses, sentences,paragraphs and
sections of this ordinance.
SECTION 3
All ordinances and parts of ordinances in conflict herewith are expressly repealed.
SECTION 4
It is the intention of the governing body, and it is hereby ordained, that the provisions of
this ordinance shall become effective and be made a part of the Code of Ordinances, City of
Tybee Island, Georgia, and the sections of this ordinance may be renumbered to accomplish such
intention.

the accommodation of movable seats in the largest assembly room or area.
(4) Public and private elementary and secondary schools (except assembly halls, auditoriums and
gymnasium used in conjunction therewith), One parking space for each 200 square feet of
gross floor area devoted to such use.
(5) Private docks. At least two off-street parking spaces must be provided for any private dock
proposed for construction on a lot that has not been otherwise improved. In the event that a
private dock is proposed on a lot that has not been improved, the parking must be off-street (not

(C) Control of access to structures used for residential purposes including but not limited to single family,
duplex, triplex, two family, multifamily, townhomes, apartments, time shares, and condominiums
whether owner occupied or held for rental. In order to promote the safety of motorists and
pedestrians, the following regulations shall apply to all newly constructed driveways:
(1) A driveway opening which connects a lot with a public street shall not be greater than 25 feet in
width at the property line. Driveways that serve duplex lots shall not have a width greater than
15 feet per unit measured at the property line. This section is not intended to prevent the
installation of flared driveway ends. These flared ends, when constructed in accordance with
adopted standards and specifications, shall not count towards the width of the driveway.
(2) There shall be no more than two driveway openings on any lot of any width. The total of the
widths at the property line of two driveway openings shall not be greater than 25 feet.

adequate space available and other access is not feasible, staff may permit a reduction in the
distance to an intersection from a driveway in order to permit safe access to the property
provided the speed limit on abutting or adjacent roads is 30 miles per hour or less,
(4) No curb on any city street or right-of-way shall be cut or otherwise altered without prior written
approval of the designated city official.
(5) All newly constructed and replacements of more than 50 percent of existing driveways
serving residential uses shall be constructed of materials designed to allow retention of
the first one-inch of stormwater.
