Grand Harbor Subdivision Green Island Road

Below is text from Grand Harbor Subdivision description about the dock.


1.0 Introduction

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

tidal waters.

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.

Floating Docks 325’ x 10’ / 3,250 300’ x 10’ / 3,000 6,250

Total 8,806

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
