TREE PROTECTION
A.
The purpose of these standards is to facilitate the preservation, planting and/or replacement of trees and to prevent the indiscriminate removal of trees in the city without denying the reasonable use and enjoyment of real property as a part of land development in the city.
B.
The City of Stockbridge city council hereby finds that the preservation of existing trees is a public purpose that protects the public health, safety, general welfare, and aesthetics of Stockbridge and all its citizens.
C.
Stockbridge citizens enjoy many benefits that can be directly attributed to our trees.
1.
Trees produce oxygen, which is essential to the well-being of all animal life, including humans.
2.
Trees help to reduce the amounts of airborne pollutants.
3.
Trees and their foliage intercept dust and particulate matter, thereby helping to purify the air.
4.
Trees and their root systems reduce soil erosion and stormwater runoff. This decreases sedimentation problems and improves water quality.
5.
Trees provide food and shelter for wildlife.
6.
Trees provide screening, which in turns aids in the reduction of noise and glare.
7.
Trees help moderate our air temperature to provide us with a comfortable environment.
8.
Trees provide scenic amenities to soften the harshness of city buildings and streets. They are aesthetically pleasing to all that view them.
9.
Trees may affect property values and can have a positive impact upon the economy of an area.
10.
Trees enhance the natural functions of streams and related buffers.
D.
The purpose of these standards is to provide standards for the preservation of trees as part of the land development process.
E.
The purpose of these standards is to prevent clear-cutting and mass grading of land that results in the loss of mature trees, and to ensure appropriate replanting when tree loss does occur.
F.
The purpose of these standards is to protect trees during construction to enhance the quality of life in the city.
G.
The purpose of these standards is to protect trees in construction of public facilities and utilities.
A.

"Buffer" means land area used to visibly separate one (1) parcel or land use from another through screening and physical distance to shield or block noise, light, glare, visual or other conditions, and to minimize physical passage to dissimilar uses. Buffers also protect the water resources of Georgia when adjacent to streams. Buffer widths vary depending upon the zoning district and the adjacent zoning district and conditions of zoning. Specific types of buffers include:
1.
"Natural/undisturbed buffer" means land area in which there is no disturbance, including, but not limited to, removal of understory trees or vegetation, except for maintenance or removal of hazardous and/or invasive trees and plants, or for approved perpendicular access and utility crossings. Existing vegetation may qualify to be a natural buffer, if sufficient vegetation exists within the required buffer width, the vegetation can be fully protected during construction, and the existing vegetation can be proven to be substantially similar to the required plantings of a new buffer and/or is sufficiently visibly dense to be accepted by the city as equivalent to a planted buffer once mature.
2.
"Enhanced natural buffer" means land area where an existing natural buffer is found to be inadequate and therefore requires additional vegetative screening. No disturbance is allowed except for maintenance or removal of and/or invasive trees and plants, or for approved perpendicular access, utility crossings and the addition of vegetative screening.
3.
"Maintained landscape buffer" means land area in which grading is allowed and re-vegetation to a buffer is required specific to a zoning case. Buffer must be replanted but also maintained per approved landscape plan and not allowed to revert to a natural/undisturbed buffer.
4.
"Stream buffer (State)" means "The area of land immediately adjacent to the banks of State waters in its natural state of vegetation, which facilitates the protection of water quality and aquatic habitat." The definition of stream buffer is governed by Georgia Law, O.C.G.A. § 12-7-3(2).

Example, a twelve-inch diameter tree at breast height (twelve (12) inches DBH) would have a twelve-foot radius circle (twenty-four-foot diameter circle) which represents the critical root zone (CRZ).
"Dead, dying, or hazardous tree (DDH)" means a tree that has structural defects in the roots, stem, or branches that may cause the tree or a part of the tree to fail, where such failure may cause property damage or personal injury.
"Tree defects." Tree defects can be of two (2) kinds: Injury or disease that seriously weakens the stems, roots, or branches of trees, predisposing them to fail or structural problems arising from poor tree architecture. Tree hazards include dead or dying trees, dead parts of live trees, or unstable live trees due to structural defects or other factors that are within striking distance of people or property.
"Deciduous tree" means a tree that drops foliage at one (1) season of the year, generally in autumn.

"Land disturbance permit (LDP)" means any permit other than a building permit issued by City of Stockbridge that authorizes clearing or grading activities on a site or portion of a site. Said permit may be clearing, clearing and grubbing, grading, or development permit as defined and authorized under the development regulations of the City of Stockbridge.
"Landscape strip" means land area located within the boundary of a lot and required to be set aside and used for landscaping upon which only limited encroachments are authorized.
"Native plant" means a plant that is a part of the balance of nature that has developed over hundreds or thousands of years in a particular region or ecosystem. Note: The word native should always be used with a geographic qualifier (that is, native to the Southeast [for example]). Only plants found in this country before European settlement are considered to be native to the United States.
"Pervious surface" means those areas which do not prevent or impede the infiltration of stormwater into the soil as it entered in natural conditions prior to or after development.

"Buffer" means land area used to visibly separate one (1) parcel or land use from another through screening and physical distance to shield or block noise, light, glare, visual or other conditions, and to minimize physical passage to dissimilar uses. Buffers also protect the water resources of Georgia when adjacent to streams. Buffer widths vary depending upon the zoning district and the adjacent zoning district and conditions of zoning. Specific types of buffers include:
1.
"Natural/undisturbed buffer" means land area in which there is no disturbance, including, but not limited to, removal of understory trees or vegetation, except for maintenance or removal of hazardous and/or invasive trees and plants, or for approved perpendicular access and utility crossings. Existing vegetation may qualify to be a natural buffer, if sufficient vegetation exists within the required buffer width, the vegetation can be fully protected during construction, and the existing vegetation can be proven to be substantially similar to the required plantings of a new buffer and/or is sufficiently visibly dense to be accepted by the city as equivalent to a planted buffer once mature.
2.
"Enhanced natural buffer" means land area where an existing natural buffer is found to be inadequate and therefore requires additional vegetative screening. No disturbance is allowed except for maintenance or removal of and/or invasive trees and plants, or for approved perpendicular access, utility crossings and the addition of vegetative screening.
3.
"Maintained landscape buffer" means land area in which grading is allowed and re-vegetation to a buffer is required specific to a zoning case. Buffer must be replanted but also maintained per approved landscape plan and not allowed to revert to a natural/undisturbed buffer.
