§ 9.6. Plans and construction.

9.6.1.

No sanitary sewer shall be accepted by the county without an as-built drawing showing the horizontal and vertical alignment of the sewer system, the locations of all manholes, sewer connections, piping materials, required easement limits and junctions, and property lines. This should be provided in the form of plans, profiles, and plats; when possible, an electronic copy of the required data (compatible with the Fulton County Geographical Information System) should be submitted.

9.6.2.

No storm sewer shall be accepted by the county without an as-built drawing showing the horizontal and vertical alignment of the sewer system; the locations of all manholes, junctions, detention ponds, retention ponds, and sewer system outfalls discharging into ditches or creeks; sewer connections, piping materials, required easement limits; and property lines. This information shall be provided in the form of plans, profiles, details, sections and plats and when possible in an electronic form compatible with the Fulton County Geographical Information System and the applicable department of public works data base.

9.6.3.

In the case of single family residential subdivisions, by written application, the owner may request that Fulton County assume partial maintenance responsibility of drainage facilities, effective after the expiration of the initial maintenance 15 months. Within 60 days after receipt of such application, the director shall respond in writing to the owner/applicant. Such response shall set forth additional terms and conditions for acceptance. However, maintenance by Fulton County shall be limited to ensuring the functional adequacy of such drainage structures. Maintenance responsibility shall remain partially with the homeowners' association unless and until, and only to the extent that, the homeowners' association is expressly relieved of such responsibility pursuant to and in accordance with a written instrument signed by the director. Appropriate easements shall be executed and recorded pursuant to this paragraph. For all other types of development, responsibility for maintenance of storm sewer system and detention ponds, including but not limited to, periodic silt removal to maintain functional integrity, will remain the responsibility of the owner. Maintenance responsibility shall constitute an obligation running with the land and shall be binding upon the owner's executors, administrators, heirs, successors, and successors-in-title.

The owner/developer shall provide stabilization, including vegetation, and installation of security fences for safety purposes at detention facilities, as prescribed, prior to approval of the final plat by the director.

9.6.4.

Any single-family detached home which involves less than 10,000 square feet of cleared area or all impervious surface areas combined and is in excess of 2,000 feet from the Chattahoochee River, shall be exempted from the provisions of a hydrology study. In no such case, however, shall grading involve over 25 percent of the total land area. Sites within 2,000 feet of the Chattahoochee River shall be developed in accordance with the Atlanta Regional Commission's vulnerability analysis, as determined by the director.

9.6.5.

All engineering and construction, regardless of whether such engineering or construction is being accomplished on public land or on public easements, shall meet the minimum requirements of these regulations.
