ARTICLE III. TREE CONSERVATION AND LANDSCAPE ORDINANCE*

Sec. 10-81. Purpose.

This tree conservation and landscape ordinance has been developed to benefit the environmental and aesthetic quality of the City of Newnan. The intent is to create an opportunity and promote conservation of the city's natural resources and grow in a way that will provide a healthy environment for Newnan's future. The purpose of this article is to provide standards for the conservation of trees as part of the land development process; to prevent massive grading of land, both developed and undeveloped, without provision for replacement of trees; and to conserve trees during construction whenever possible in order to enhance the quality of life within the City of Newnan. The regulations of this tree conservation and landscape ordinance shall be the definitive, unless otherwise directed by the Zoning Ordinance or City Code. The benefits derived from this article include:

*Editor’s note—Ord. No. 2022-5, § I, adopted Feb. 2, 2022, repealed and readopted art. III to read as set out herein. Former art. III, §§ 10-81—10-85 pertained to similar subject matter and derived from Ord. No. 00-01, § 1, adopted January 11, 2000; Ord. No. 00-36, adopted Nov. 14, 2000; and Ord. No. 03-15, § 1, adopted June 26, 2003.

Sec. 10-83. Applicability.

The terms and provisions of this article shall apply to all land disturbance activities, including tree removal, as outlined within this article, and spelled out in section 10-84, (Permitting and process). (Ord. No. 2022-5, § I, 2-2-22)

Sec. 10-84. Permitting and process.

These landscape ordinance requirements are intended to set minimum standards for quality development and environmental protection. Site conditions or other reasons may justify the need to request an alternative method of compliance. Alternative landscape plans may be considered when the applicant cannot meet one or more of the specific requirements of this article because:

The applicant must submit an alternative landscape plan indicating proposed landscaping, that includes a list of landscaping requirements not met, a detailed description of the alternatives proposed, and a written explanation of how the proposed plan fulfills the spirit and intent of the landscape requirements. If an agreement can not be reached between the city landscape architect and the applicant, the applicant may then appeal to the city's tree commission. The alternative landscape plan must be submitted to and reviewed by the tree commission. In making a recommendation regarding the alternative landscape plan, the tree commission must find that:

In those instances where it has been determined by the tree commission that the available land within a project site cannot bear the total number of tree density units required by this article, the city has established an alternative compliance program. Alternative compliance shall be limited to a contribution to the city's tree fund as described herein.

The City of Newnan has established a tree bank that shall receive payments made by property owners in lieu of planting additional tree density requirements as approved by the tree commission, in addition to forfeited bonds or forfeited escrow funds. Funds in the tree bank shall be administered by the city landscape architect.

Where it is determined by the tree commission that it is impractical or impossible to fully meet the tree density requirements for a site, the portion of the tree density that cannot be accommodated on the site alternative compliance may be satisfied by a payment into the tree bank that shall be made prior to the issuance of a tree removal or land disturbance permit. The amount of the payment shall be calculated based on the cost of purchase and installation of the additional trees and verified by the city landscape architect.

The tree bank funds shall be available for use by the city for the establishment, maintenance, improvement, and expansion of tree cover on public property. The expenditure of tree bank funds shall be permitted for various activities related to tree conservation including but not limited to: purchase of trees, planting of trees, maintenance of trees, purchase of greenspace, or funding of tree care educational programs.

Sec. 10-85. Tree conservation and protection.

The existing trees in Newnan are a community resource worth conserving, protecting and maintaining. Careful thought and consideration is expected to be given to conserving trees in the development process. It is required that all reasonable efforts be made to conserve and protect existing specimen trees and/or groups of trees. (Reasonable effort shall include, but not limited to, alteration of building design, alternate building location, parking area, detention area, drainage system, or relocation of utilities).

The following guidelines and standards shall apply to trees proposed to be retained for credit toward meeting the site density factor on a property.

In order to qualify for tree replacement density credit, all replacement trees shall be at least eight feet tall planted and have a trunk of not less than two caliper inches. Multi stemmed canopy/shade trees shall count only the largest trunk for caliper. All multi-stemmed understory/flowering replacement trees shall have a minimum of three canes, each with a minimum one inch caliper extending clear at least to a height of four feet. All evergreen replacement trees shall be at least a seven gallon size, six feet tall planted, and have a main trunk of not less than two caliper inches. No more than 40 percent of any one genus may be included in any replanting plan.

SDF = (total site area, in acres, minus zoning buffers, stream buffers, floodplain, or delineated wetlands) x 12 Credit for existing trees proposed to be conserved on the site shall be calculated by multiplying the number of trees (by diameter) times the units assigned in Table 2 Credit For Existing Trees. Credit shall be given all trees conserved on a property having a diameter of ten inches or more, except trees located in a required zoning buffers, stream buffers, floodplain, or delineated wetlands. Credit for new trees proposed to be replaced on the site shall be calculated by multiplying the number of trees (by diameter) times the units assigned in Table 3 - Credit For Replacement Trees. Credit shall be given all new trees replaced on the property except for new trees of less than two inches in diameter and new trees planted in a required zoning buffers, stream buffers, floodplain, or delineated wetlands. The number of new trees planted is determined as follows:

Using Table 2 - Credit For Existing Trees calculate the existing density factor (EDF) of trees ten inch diameter (DBH) or greater which will remain on the site and be protected during construction.

DBH = diameter at breast height (four and one half feet above ground)

9.6 To calculate the replacement density factor (RDF), subtract the existing density factor (EDF) from the site density factor (SDF).

RDF = SDF - EDF Example procedure for calculating the required replacement density factor (RDF):

STEP 1 = Calculate the site density factor (SDF) by multiplying the number of site acres by 12.

Example = 1.89 acres x 12 = 22.68 units.

STEP 2 = Calculate the existing density factor (EDF) of trees that will remain on site to be protected during construction. EDF is determined by converting the tree diameter (DBH) of individual existing trees to density factor units, using Table 2 Credit For Existing Trees. These units are then totaled to determine the EDF.

Example = A total of 10 trees will remain on the 1.85 acre site in Step 1. The trees include: natural topography of the site and protection to the maximum number of trees.

Number of DBH Trees x Units Total 12"

3 x 0.8 2.4 18"

4 x 1.8 7.2 20"

3 x 2.2 6.6 Adding together the units of all remaining trees, the sum total of units = 16.20 Units.

Since the existing density factor (EDF) is less than the required site density factor (SDF), then replacement trees are required. The minimum site density factor (SDF) for a 1.893 acre site, established in Step 1 has not yet been met.

STEP 3 - Calculate the replacement density factor (RDF) by subtracting the existing density factor (EDF) (Step 2) from the site density factor (SDF) (Step 1). RDF = EDF - SDF Example = RDF = 22.68 (SDF) - 16.20 (EDF)

22.68 - 16.20 = 6.48 (RDF)

STEP 4 - The replacement density factor (RDF) can be converted back to caliper inches using Table 3 - Credit For Replacement Trees. Any number or combination of transplantable size trees can be used so long as their total density factor units will equal or exceed the replacement density factor (RDF).

Example = on the 1.893 acre site the following number and size of trees will be planted as replacement trees:

Number Size Species x Density Factor = Total Units 05 2"

Dogwood x 0.5 = 2.50 02 2"

Blackgum x 0.5 = 1.00 05 3"

Red Maple x 0.6 = 3.00 Adding together the units of proposed replacement trees, the sum total of units =

Proposed replacement units of 6.50 is equal to the replacement density factor (RDF) of 6.48 units, thus minimum replacement requirements have been met.

Use Table 3 - Credit For Replacement Trees to determine the number and size of trees that must be planted. Any combination of transplantable size trees can be used, so long as their total density factor units equal or exceed the RDF. Replacement trees must meet the minimum landscaping requirements set forth in section 10-86(2).

Existing trees proposed to be retained and new trees proposed to be planted in order to meet the buffer requirements of the Zoning Ordinance or conditions of zoning, special use or variance approval shall not be considered in fulfilling the requirements of this section concerning site tree density factors. Buffer requirements are considered to be in addition to the minimum site tree density requirements. See appropriate zoning district classification for any additional landscaping or buffering requirements.

Tree density unit credits are given for existing trees that are saved during the site development process, with more credits given to specimen trees. In order to encourage the preservation of specimen trees and the incorporation of these trees into the design of projects, additional density credit will be given for specimen trees which are successfully saved by a design feature specifically designated for such purpose. Credit for any specimen tree thus saved for such purpose would be two times the assigned unit value in Table 2 - Credit For Existing Trees. Increased credits can also be earned by conserving non specimen groups of trees 18 inches and larger.

The following criteria are used by the city to identify specimen trees. Both the size and condition criteria must be met for a tree to qualify:

A lesser sized tree can be considered a specimen tree, if in the judgement of the city landscape architect:

The following criteria are used by the city to identify specimen tree stands, which is a contiguous grouping of four or more trees which have been determined to be of high value in the opinion of the city landscape architect. Determination is based upon the following criteria:

Any tree, designated on the tree protection plan to be saved, which is damaged during construction or as a result of construction, as determined by the city landscape architect, shall be replaced with a tree or trees equal to the unit value of the tree damaged. However, any specimen tree damaged as described above shall be replaced with trees equaling an inch for inch replacement of the tree damaged. (Ord. No. 2022-5, § I, 2-2-22)

Sec. 10-86. Landscape plan and requirements.

A landscape plan prepared by a landscape architect, registered in the State of Georgia, will be required for any development, with the exception of the construction of individual single family and detached dwellings, in the City of Newnan. A landscape plan shall be prepared for any project wherein buffer areas or other landscaping areas or treatments are required by this article, the Zoning Ordinance, conditions of zoning, special use or variance approval, or other regulations of the City of Newnan, and shall be approved prior to the issuance of a land disturbance permit. A landscape plan is required for single-family residential subdivision development plats. The plan shall address common areas including, but not limited to, such areas as parks, active and passive recreation areas, amenity areas, buffers, landscape strips, and entrances.

Policy on Practicability Analysis for Runoff Reduction Introduction Runoff reduction practices are stormwater Best Management Practices (BMPs) used to disconnect impervious and disturbed pervious surfaces from the storm drainage system. The purpose is to reduce post-construction stormwater runoff rates, volumes, and pollutant loads. Runoff reduction is more than simple infiltration. The Runoff Reduction Volume (RRv) is the retention volume calculated to infiltrate, evapotranspirate, harvest and use, or otherwise remove runoff from a post-developed condition to more closely mimic the natural hydrologic conditions.

Certain conditions, such as soils with very low infiltration rates, high groundwater, or shallow bedrock, may lead a local jurisdiction to waive or reduce the runoff reduction requirement for proposed site development on a case-by-case basis. If any of the stormwater runoff volume generated by the first 1.0" of rainfall cannot be reduced or retained on the site, due to site characteristics or constraints, the remaining volume shall be increased by a multiplier of 1.2 and shall be intercepted and treated in one or more best management practices that provide at least an 80 percent reduction in total suspended solids.

The Policy on Practicability Analysis for Runoff Reduction (practicability policy) was developed to provide guidance about the site conditions and supporting documentation that could justify a "Determination of Infeasibility" for the runoff reduction requirement. This practicability policy does not address infeasibility for linear transportation projects being constructed by the local jurisdiction, other local governments, or authorities.

The practicability policy is based on the following principles:

The local jurisdiction is responsible for the review of land development applications and determination that it is infeasible to apply the runoff reduction requirement on part or all of a proposed site development. Local jurisdictions may choose to make substantive changes or otherwise customize this practicability policy. These further changes and customizations are allowable so long as their substance meets the requirements of a local jurisdiction's MS4 permit. EPD is responsible for evaluating MS4 permit and District Plan compliance, which includes verifying whether changes and customizations are "at least as effective." EPD has reviewed this document and their comments have been incorporated.

Conditions that may warrant a Determination of Infeasibility The GSMM provides broad guidance about conditions that may lead a local jurisdiction to waive or reduce the runoff reduction requirement. The following conditions may warrant a Determination of Infeasibility.

Supplemental Materials The District has prepared supplemental materials to support the implementation of this practicability policy. Appendix A is meant for internal use and provides an overview of the steps a local jurisdiction could take to implement the practicability policy and issue a Determination of Infeasibility. Appendix B has a template the local jurisdiction could use as a runoff reduction infeasibility form.

Appendix A: Overview of Processing a Determination of Infeasibility Obtaining a Determination of Infeasibility Determination of Infeasibility is not an all or nothing proposition. Designers must demonstrate that they have explored all avenues to meet the runoff reduction standard. If this is determined to be infeasible, they must attempt to provide the maximum percentage of RRv on site as feasible. Only after all attempts to provide any RRv on site are exhausted will the local jurisdiction consider a Determination of Infeasibility. The following process is recommended to:

The market value of the building means:

This term includes structures which have incurred "substantial damage" regardless of the actual amount of repair work performed. For the purposes of this definition, "substantial improvement" is considered to occur when the first alteration of any wall, ceiling, floor, or other structural part of the building commences, whether or not that alteration affects the external dimensions of the building. The term does not, however, include those improvements of a building required to comply with existing health, sanitary, or safety code specifications which are solely necessary to assure safe living conditions, which have been pre-identified by the code enforcement official, and not solely triggered by an improvement or repair project.

Substantially improved existing manufactured home park or subdivision is where the repair, reconstruction, rehabilitation or improvement of the streets, utilities and pads equals or exceeds 50 percent of the value of the streets, utilities and pads before the repair, reconstruction or improvement commenced.
