Below is text from Grand Harbor Sudivison description about the dock.
Grand Harbor Development Group, LLC (Applicant) is seeking authorization under
Section 10 of the Rivers & Harbors Act of 1899 (RHA) and the Coastal Marshlands
Protection Act of 1970 (CMPA) to construct a community dock to service a 45-lot
residential development located on Franklin Creek, east of Green Island Road, in
unincorporated Chatham County, Georgia (31.910999 N, -81.068814 W).
The proposed community dock will provide water access for forty-five (45) residents of
the Grand Harbor development. The upland component of the project consists of a 11,509
ft2 common area to access the marshlands component of the project. The marsh component
of the project consists of a pile-supported dock that would occupy 9,968 ft2 (0.22-acre) of
2.0 Existing Conditions
The proposed project is located on the western shoreline of Franklin Creek, approximately
1,400’ north of Delegal Creek. The subject property is approximately 36 acres in size and
is currently undeveloped. Seven (7) existing private docks are located on Franklin Creek
upstream from the proposed community dock location. No docks are located on Franklin
Creek downstream of the proposed facility. The CMPA jurisdiction limits were verified
by CRD staff via letter of October 14, 2021.
3.0 Project Description
Grand Harbor is a planned forty-five (45) lot residential subdivision. The proposed
community dock will provide water access and mooring for the Grand Harbor residents.
3.1 Marshlands Component
The marshlands component of the project would occupy 8,806 ft2 (0.20-acre) of tidal
waters and consists of a 6’ x 457’ aluminum walkway on wood pilings (281 l.f./1,686 ft2 in
CMPA jurisdiction), a 20’ x 20’ covered fixed pier, a 5’ x 40’ aluminum gangway, a 10’ x
27’ ramp landing floating dock, and a 10’ x 625’ floating dock (see Table 1). The dock will
extend 52’ beyond MLW on the downstream end of the dock where the creek is +/-155’
wide at MLW (approximately 33% of the waterway) and will extend 78’ beyond MLW on
the upstream end of the dock where the creek is +/-247’ wide at MLW (approximately 31%
of the waterway).
The two (2) slips at the gangway landing would be reserved for loading/unloading of
passengers and/or gear. The remaining slips would be utilized on a first-come first-served
basis for residents of the development. The construction of the floating dock would be
phased, with approximately half of the floats being installed upon approval by the
Committee, and the second phase upon providing CRD staff satisfactory documentation of
the utilization of the first phase of the facility.

Walkway 281 / 1,686 n/a 1,686
Fixed Deck 20’ x 20’ / 400 n/a 400

Floating Docks 325’ x 10’ / 3,250 300’ x 10’ / 3,000 6,250
3.2 Upland Component
The upland component of the project consists of an 11,509 ft2 common area that includes
4,866 ft2 of pervious pavement parking for automobiles and golf carts, and a 10’ wide
pervious gravel walkway (1,380 ft2
) providing access through uplands to the marshlands
component of the project. The 302 ft2 area within the 50’ CMPA buffer outside of the
gravel walkway will be landscaped with native vegetation to prevent erosion and provide
for stormwater filtering. No impervious surfaces are present within the upland component
and no direct discharge of stormwater into coastal marshlands would result from
construction of the upland component of the project.
4.0 Alternative Sites Considered
The Grand Harbor development is designed and marketed to potential buyers that would
desire waterfront living along with unrestricted access to coastal waters provided by on-site
mooring facilities. The applicant considered utilization of existing off-site alternative
access facilities to provide residents the opportunity to access coastal waters. There is a
public boat ramp approximately 3 miles from the project site on the Skidaway River on the
south side of Diamond Causeway. However, this facility is very popular with county
residents and can be extremely crowded on weekends and holidays, resulting in long wait
times to load and unload and lack of parking. Use of this facility would not meet the
applicant’s overall project purpose, and would require either on-site or off-site boat and
trailer storage. Due to the prime location of the proposed facility in close proximity to the
Atlantic Ocean, some of the vessels may be larger than average and be difficult to tow and
store. Providing on-site mooring at the proposed community dock will free up space for
non-waterfront and transient boaters that may better utilize alternative public facilities.
The project as proposed represents the most feasible option to provide necessary wet slips
for residents of Grand Harbor and the increased demand that will occur in this area while
protecting the general public’s ability to continue to use existing public facilities without
undue demand and crowding.

5.0 Needs Assessment
The proposed project would provide water access for the forty-five (45) residents at Grand
Harbor. An average dock space of twenty-five feet (25’) for each lot would require a
minimum mooring capacity of 1,125’. As designed, fifty (50) twenty five-foot floating
dock sections will provide mooring on both sides of the floats, resulting in 1,271 linear feet
of mooring space. Two (2) twenty-five foot sections of float at the gangway / floating dock
landing would be utilized for loading/unloading of passengers and/or gear to alleviate long
walks to the outer limits of the floating docks. The proposed project will provide access to
coastal waters with a very limited amount (0.20-acre) of structure over coastal marshlands.
The riparian lots on the remainder of the property will be deed-restricted to prohibit
construction of additional private docks.
Phase I of the construction would be commenced upon approval and would consist of the
installation of the thirteen (13) upstream floats totaling 325’ in length (600 l.f. mooring
space, 3,250 ft2
). Upon providing suitable justification to CRD staff that Phase I is being
utilized and upon approval, Phase II of the construction would consist of the installation of
the remaining twelve (12) downstream floats at 300 l.f. in length (600 l.f. of mooring
space, 3,000 ft2
