City of Tybee Island
Dune Restoration and Improvements to Pedestrian Promenade
Project Location
Project Location
The proposed project area includes
the dry sand beach landward of the
Ordinary High Water Mark
(OHWM) immediately adjacent to
the Walter Parker Pier and Pavilion,
extending to south of 19th Street,
and extending landward across the
existing parking lot.
Project Description
The applicant is proposing dune restoration, modification to existing DNR-
Approved Vehicular Access Points, and enhancement to an existing pedestrian
promenade.
Project Site
•The applicant’s dune restoration consists of placing approximately 20,000 cubic
yards of beach quality sand obtained from an upland source in three (3) identified
areas on the beach, planting native vegetation, installing sand fencing, and
modifying two existing vehicular access routes within the project area.
Project Description: Dune Enhancement
•Project Area 1 was
completely washed over
during recent storm
events. Approximately
43,475 square feet of beach
front will have
approximately 11,000
cubic yards of sand added
and sculpted into a dune
field that would average
approximately 8ft. in
height.
Project Description: Dune Enhancement
•Project Area 2 experienced severe
erosion and scarping, as well as a
washout at 18th Street during recent
storm events. Approximately
27,870 square feet of beach will
have approximately 5,000 cubic
yards of sand added and sculpted
into a dune field that would average
approximately 6ft. in height. The
applicant is proposing to
permanently close the existing
vehicular access point at 18th Street.
•Public access to the beach at 18th
Street will be retained for
pedestrian use only.Hurricane Irma Post-Irma
Project Description: Dune Enhancement
•Project Area 3 also experienced
erosion and scarping during
recent storm events.
•Approximately 1,500 square feet
of beach will have
approximately 4,000 cubic
yards of sand added and
sculpted into a dune field that
would average approximately
4ft. in height.
•This area will also have an
improved vehicular access point
at 19th Street.
Project Description:
Modification of Existing DNR-Approved Vehicular Access Points
•The improved vehicular access point at 19th
Street will consist of subsurface stabilization that
would be comprised of a series of Permashield
sand bags filled with beach quality sand obtained
from an upland source. The subsurface stabilized
vehicular access design calls for the strategic
placement of specially engineered sand bags
filled with beach quality sand, an engineered
fabric overlay within the travel corridor and
native vegetation.
•The subsurface stabilized vehicular access will be
constructed in a manner that will address storm
surge penetration experienced in recent storm
events, while providing City of Tybee Island
emergency vehicles, police vehicles, marine
rescue vehicles and authorized City of Tybee
Island personnel reliable ingress and egress to
the dry sand beach at all tidal stages.
Project Description:Enhancement to the Existing Promenade
•In an effort to help
stabilize the restored
sand dunes along the
entire project area, the
applicant is proposing
the installation of salt
tolerant, native
dunescape plants,
temporary irrigation
and sand fencing that
would be strategically
located throughout the
project area seaward
and landward of the
new dune field.
Project Description:Enhancement to the Existing Promenade
•The proposed improvements to the existing pedestrian promenade include
improvements to the hardscape areas landward of the beach in order to enhance
pedestrian opportunities while creating a more naturalized area for passive activities.
Existing public amenities such as parking, sidewalks, seating, showers and restrooms
will remain.
