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

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 amend the Code to provide in Section 3-
080(C) relating to specifications for driveways, to repeal conflicting ordinances, to establish an
effective date, and for other purposes.
NOW, THEREFORE, be it ordained by the governing authority of the City of Tybee
Island that the Code of Ordinances, Section 3-080(C), Off street parking, be hereby amended so
that hereafter the ordinance shall read as hereinafter provided.
SECTION 1
The Code of Ordinances is hereby amended so as amend Section 3-080(C) regarding
driveway specifications which shall read as follows:
Sec. 3-080. Off-street parking requirements.
(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:
(I) 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.
(3) No driveway opening shall be constructed within 25 feet of an intersection,measuring
from the nearest improved portion of the right-of-way. However, in any instance where there is not
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. Driveway requirements specified in this Section,
notwithstanding, staff may issue a permit to a residential property owner to place approved materials
in the city right of way,provided the owner is informed and acknowledges that the city will maintain
the right to initiate any required action within the right of way and that permitting materials in the
right of way shall not create any vested rights in the property owner and such permission may be
terminated at any time. In addition, such permit by staff may only be made in the event the
improvement does not create a safety issue or interfere with city metered parking and does not violate
any city ordinance including, but not limited to,the requirements of Section 3-165 to maintain 65%of
the property setback area as greenspace. If the staff of the building and zoning department finds that a
request under this section needs or should have additional review for any reason, it may request
review by the mayor and council or, if the staff of the building and zoning department declines the
applicant's request,the applicant may apply for the granting of the permit which will result in the
application going to the mayor and council. However,before the mayor and council, a public hearing
is not required but action may only be taken at a public meeting of the mayor and council.
(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 percent
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 percent of an improved driveway. The retention requirement is
based on a 24-hour,25-year Tybee III 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 four-inch by eight-inch with minimum five-sixty-fourths-inch
average continuous joints/borders with eight one-eighth-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 state licensed design
professional must be reviewed and approved by the city. See engineering fee information in
subsection(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 four-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 eight
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
2
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 one to two percent 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 subsection(a). The area between
the drive strips is to be flush or one-eighth-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 one-eighth-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 four to eight
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 state licensed design professional
demonstrating compliance with the retention requirement of this section.
