§ 74-40. Plan requirements.

(a)

Plans must be prepared to meet the minimum requirements as contained in section 74-43 of this article. Conformance with the minimum requirements may be attained through the use of design criteria in the Manual for Erosion and Sediment Control in Georgia, or through the use of more stringent, alternate design criteria which conform to sound conservation and engineering practices. The Manual for Erosion and Sediment Control in Georgia is hereby incorporated by reference into this article. The plan for the land-disturbing activity shall consider the interrelationship of the soil types, geological and hydrological characteristics, topography watershed, vegetation, proposed permanent structures including roadways, constructed waterways, sediment control and stormwater management facilities, city ordinances, and state laws.

(b)

Data required for site plan.

(1)

Narrative or notes, and other information: Notes or a narrative shall be written on the site plan, in the general notes section, or in the erosion and sediment control notes section of the plan.

(2)

Description of existing land use at project site and description of proposed project.

(3)

Name, street address, and phone number of the property owner.

(4)

Name and phone number of 24-hour local contact who is responsible for erosion and sedimentation controls.

(5)

Total size of site, project, or phase under construction, and total size of disturbed area in both square feet and acres.

(6)

Construction activity schedule showing the sequence of major activities involving land-disturbing activity to be completed in chronological order, including, but not limited to, anticipated starting and completion dates for the project, initial installation of BMPs, clearing arid grubbing activities, grading, utility installation, and temporary and final stabilization in accordance with section 74-43(f). Include the following statement in bold letters: "The installation of erosion and sedimentation control measures and practices shall occur prior to or concurrent with laud-disturbing activities."

(7)

Stormwater and sedimentation management systems' storage capacity, hydrologic study, and calculations, including off-site drainage areas.

(8)

Vegetative plan for all temporary and permanent vegetative measures, including species, planting, dates, and seeding, fertilizer, lime, and mulching rates. The vegetative plan shall show applicable options for year-round seeding in accordance with Chapter 6 Section II, Vegetative Measures, of the Manual for Erosion and Sediment Control in Georgia.

(9)

Detailed drawings for all structural erosion control practices. Detailed drawings shall either follow guidelines set forth in the Manual for Erosion and Sediment Control in Georgia, or shall adhere to more stringent, alternate design criteria which conform to sound conservation and engineering practices.

(10)

In accordance with section 74-41(a), the following maintenance statement in bold letters: "Erosion and sedimentation control measures will be maintained at all times. If full implementation of the approved plan does not provide for effective erosion and sediment control, additional erosion and sediment control measures shall be implemented to control or treat the sediment source."

(c)

Maps, drawings, and supportive computations shall bear the signature/seal of a certified design professional. The certified plans shall contain:

(1)

Graphic scale and north point or arrow indicating magnetic north.

(2)

Vicinity maps showing location of project or site, and existing streets and drainage paths within one mile of the project.

(3)

Boundary line survey.

(4)

Delineation of disturbed areas within project boundary.

(5)

Existing and planned contours, with an interval in accordance with the following:

Map Scale	Contour Interval, ft.	Ground Slope
1 inch = 100 ft. or larger scale	0.5 or 1	Flat 0—2%
	1 or 2	Rolling 2—8%
	2, 5 or 10	Steep 8%

 

(6)

Adjacent areas and features including, but not limited to, streams, lakes, wetlands, and residential areas, which may be affected by the proposed land-disturbing activity.

(7)

Proposed structures or additions to existing structures and paved areas.

(8)

State waters buffers required by section 74-43(c)(15) and 74-43(c)(16), and the riparian buffers required by Article VII Chapter 74 sections 303(a), 303(b), 303(c), and 303(d).

(9)

Where applicable, the 2,000 foot Chattahoochee River Corridor as required by O.C.G.A. § 12-5-440 et seq. and set out in Article VII Chapter 74 section 314(b), and the allowable limits of impervious surface and land-disturbing activities as specified in accordance with the certificate issued under O.C.G.A. § 12-5-445.

(10)

The specified horizontal state waters buffer along designated trout streams (the Chattahoochee River within the city) required by subsection 74-43(c)(16).

(11)

Locations of BMPs using coding symbols from the Manual for Erosion and Sediment Control in Georgia.

(12)

Detailed maintenance requirements for each BMP.

(13)

Information required by the applicable Erosion, Sedimentation and Pollution Control Plan Review Checklist, as may be amended, established by the Commission (currently available at http://www.gaswcc.org) for projects which disturb one acre or more.

(d)

Revisions. Revisions or amendments to an approved erosion and sedimentation control plan that may affect a BMP with a hydraulic component shall be certified by a design professional, and subsequently approved by the Department of Watershed Management.

(e)

A copy of the approved erosion and sedimentation control plan shall be kept at the site during all land-disturbing activities.
