Article 4, Division IV – Overlay Districts
General Provisions
Sec. 4.21 General Provisions As the name implies, overlay districts “over-lay” applicable base zoning district classifications to alter some or all of the base zoning district regulations that apply to particular sites. Overlay zoning districts work to modify or supplement the regulations imposed by base zoning district when necessary to address special situations or promote specific county planning goals. Overlay zoning is intended to be used when the base zoning district applied to an area remains generally appropriate, but when an additional, modified or eliminated requirement could help implement the county’s planning goals or address an area-specific planning, design or land use regulation issue. Certain districts are established as overlay districts, meaning that the "base" (or underlying) zoning district remains in place but the overlay adds additional provisions that override specific provisions of the base zoning district. The purpose of each of the overlay districts established in this Development Code is presented in this Section. All applicable regulations of the underlying base zoning district and of this Development Code apply to property in an overlay district unless otherwise expressly stated in the overlay district regulations. When overlay district regulations conflict with regulations that otherwise apply in the underlying base zoning district or with regulations otherwise imposed by this Development Code, the more restrictive regulations govern.

Sec 4.21 (b) O-QGD Quality Growth Development Overlay.
The O-QGD Quality Growth Development Overlay District is established to promote high-quality development in areas of the county that are largely undeveloped but in the path of rapid, substantial residential, commercial, or industrial development that is anticipated will radically change the character of the lands within the District boundaries. This District is designed to encourage high-quality development by establishing restrictions and standards to protect the natural environment, promote optimum development, and so that investment values will be maximized and will not be endangered by unsightly, undesirable, or incompatible development on adjacent properties in the foreseeable future.
The primary goals of the O-QGD overlay district are to provide a positive climate for high-quality investment and development, to provide a sense of place and orientation, to provide an attractive and functional environment, to ensure a harmony of uses and development, and to provide a comfortable, secure, and harmonious developed environment.
Any multi-family residential, commercial, office, office distribution, or industrial use within the O-QGD shall comply with the landscaping requirements of this section in addition to the applicable requirements and standards of Article 2, Article 8 and Article 9.
The location and detail of all required landscaping shall be depicted on the site landscaping plan (see the Procedures and Permits Article of this Development Code).
Minimum required landscaped area.
Each site shall have a minimum landscaped area of 25 percent. The calculated landscaped area may include tree islands within required parking areas.
Frontage landscape strip.
A minimum 25-foot wide landscape strip adjacent to the street right-of way shall be provided in such a way so as to achieve maximum screening effect, which may include installation at the road elevation or higher, based on the discretion of the Director.
Every 100 feet of linear landscape strip must include a minimum of 3 canopy trees, 3 understory trees, 2 evergreen trees, and 18 shrubs. Planting standards may be reduced up to 50% with the provision of a 5 feet tall earthen berm running the entire length of the landscape strip.
Side and rear yard landscaping.
Unless otherwise required in Article 8 of the Unified Development Code, all required side and rear yards shall be landscaped in accordance with the requirements of this article.
Other landscape areas.
All land surfaces other than those covered by permitted buildings, structures, paving, or other required site elements shall be landscaped with well-maintained grass, flowers, shrubs, or other suitable plant materials.
Natural buffers.
Natural buffers shall be supplemented with native plantings when existing vegetation on the site does not provide a minimum of 80% opacity between the proposed use and the adjacent residential district. These plantings shall include a mixture of canopy trees (50% must be evergreen), understory trees, evergreen coniferous trees and shrubs.

Sec 4.21(f) O-LF Landfill Overlay.
The O-LF Landfill Overlay District is established in order to protect properties near existing or previously closed solid waste disposal facility from well-water contamination and from the buildup of methane gas within enclosed buildings. It is the intent of this overlay district to maintain compliance with requirements imposed by the Georgia Department of Natural Resources, Environmental Protection Division (Chapter 391-3-4, Solid Waste Management).
The O-LF district is hereby established to include all areas located within ½-mile (2,640 feet) of the property line of a property on which is located a solid waste disposal facility permitted under the rules of the Georgia Environmental Protection Division, whether currently active or previously closed.
Relief from the restrictions imposed by the O-LF Landfill Overlay District may be requested under the Appeals Article of this Development Code.
Sec 4.21(g) Airport Hazard Overlay District The O-AH Airport Hazard Overlay District provides restrictions that supplement or override provisions of the underlying zoning districts beneath the airport zone, and includes all areas shown on the map labeled as such and adopted as part of the Official Zoning Map as required by Federal Aviation Regulations (FAR) Part 77.
Airfield: In this section the terms "airfield" and "airport" are interchangeable and mean airfields in Douglas County.
Approach-departure clearance surface: This surface is symmetrical about the runway centerline extended. It begins as an inclined plane (glide angle) two hundred (200) feet beyond the end of the runway at the same elevation as the runway end, and extends for 50,000 feet. The slope of this surface is fifty to one (50:1) (glide angle) for military airports, along the runway centerline extended for 25,000 feet, at which point it reaches an elevation of 500 feet above the elevation of the runway end. It then continues horizontally at this elevation for an additional 25,000 feet. The width of this surface at the starting point (200 feet from the runway end) is 2,000 feet. It flares uniformly and the width at 2.5 miles is 2,696 feet. Glide angles for other types of airports shall be determined by consultation with the county engineer.
Flight hazard: Any structure or natural growth or use of land that obstructs or restricts the airspace required for the safe flight of aircraft in landing, takeoff or maneuvering areas as or in the vicinity of the airfield.
Landing area: That part of the airfield that is used or intended to be used for landing and takeoff of aircraft.
Structure: An object, including a mobile object, constructed or installed by man, including, but without limitation, buildings, towers, cranes, smokestacks, earth formations and overhead transmission lines.
To carry out the purposes of this section, all of the land within the boundaries of the future airfields in Douglas County and within one mile of the runway centerline extended of each instrument runway affected, for a distance of 2.5 miles from each end of such runway, is hereby declared to be a compatible use zone (CUZ) divided into three sub zones. The sub zones are:
Except as otherwise provided in this section, no structure or natural growth shall be erected, altered, allowed to grow or maintained in the CUZ to a height in excess of the height specified below for each sub zone.
No use may be made of land or water within the Airport Hazard Overlay District in such a manner as to create electrical interference with navigational signals or radio communication between the airport and aircraft, make it difficult for pilots to distinguish between airport lights and others, result in glare in the eyes of the pilots using the airport, impair visibility in the vicinity of the airport, create bird strike hazards, or otherwise in any way endanger or interfere with the landing, takeoff, or maneuvering of aircraft intending to use the airport.
The limitations prescribed in this Section shall not be construed to require the removal, lowering, or other change or alteration of any structure or natural growth not conforming to the regulations of this Division as of the effective date hereof, or otherwise interfere with the continuance of any nonconforming use. Nothing contained in this Division shall require any change in the construction, alteration or intended use of any structure, the construction or alteration of which has begun prior to the effective date of this Development Code and is diligently prosecuted and completed within two years thereof.
Any person desiring to erect any structure or increase the height of any structure, or permit natural growth, or use such person's property, not in accordance with the regulations prescribed in this Division, may apply for a hardship variance under the provisions of the Procedures and Permits Article of this Code. Such variance may be allowed where a literal application or enforcement of the regulations would result in practical difficulty or unnecessary hardship and the relief granted would not be contrary to the public interest, but do substantial justice and be in accordance with the spirit of this section.
Any variance granted under Section 4.30 (f), if such action is considered advisable to effectuate the purposes of this Division and reasonable in the circumstances, may be so conditioned as to require the owner of the structure or natural growth in question to permit the airport operator at the owner's expense to install, operate and maintain thereon such markers and lights as may be necessary to indicate to airport pilots the presence of a flight hazard.
Included in any application for approval of an Airport Hazard Overlay District or for a variance under Sec.
4.21(g) there must be written approval by the Federal Aviation Administration that the property in question will be suitable for development as an airport or that the variance will not be inconsistent with FAA rules and regulations.
Section 4.21(h) Westfork and Thornton South Overlay
Depth is measured from the right-of-way.
specifically, Section 1(C) for Residential and Section 2(B)(6-7) for Non-Residential shall govern. Alternative provisions may be provided at the discretion of the Director of Development Services if it is determined that the proposed elevations would be of a similar architectural style and finish to structures currently existing in the immediate vicinity along the street frontage of the proposed structure.

Section 4.21(k) Cedar Mountain Overlay
It is comprised of geologic features that contribute to a habitat which sustains a rare botanical environment.
The predominant geologic unit underlying Cedar Mountain is Ropes Creek Metabasalt. Calcium-rich soils, such as those found over Ropes Creek Metabasalt support a disproportionately large number of rare plant species found within Georgia. Distinct rock outcroppings support unique and diverse assemblages of native plants, some of which are rare botanical species. Cedar Mountain also holds potential for the identification of rare and endangered animal species dependent on the unique ecosystem.
The Piedmont Mafic Dry-Oak Hickory Forest is threatened by forest conversion and habitat destruction. Evidence of pre-historic occupation and early settlement may contribute to understanding the early history of Douglas County. The topography changes of the wooded and granite outcrops, along with scenic long vistas, contribute to the unique sense of place in Douglas County.
It is the intent of this ordinance to identify appropriate measures to mitigate any land use or development that would potentially be a detriment to the natural, scenic or cultural environmental of this unique and valuable resource.
