City of Milton Tree Conservation Ordinance PPI• I. PURPOSE "'b -VA A. The purpose of this ordinance is to cultivate and encourage a high level of tree conservation, to promote the general provisions within this ordinance, and to develop detailed provisions within the administrative guidelines in order to implement the regulations set forth to preserve, maintain, and replant trees within the City of Milton,Georgia. The intent of the Ordinance and Administrative Guidelines is to provide standards for the conservation of trees as part of the land development, building construction and tree removal activities. It is not the intent of this ordinance to regulate individual properties where activities do not require a land disturbance, building construction, or tree removal permit. It is, however, the intent to insure that individual properties retain the required tree densities, should they require a land development, building, or tree removal permit. B. Tree protection and tree planting provide the following benefits to the citizens of Milton: 1. Trees produce oxygen and absorb carbon dioxide, thereby reducing air pollution and improving air quality. 2. Trees filter out dust, particulate matter, and airborne pollutants, thereby improving air quality. 3. Tree roots hold the soil, thereby reducing soil erosion and sedimentation and improving water quality. 4. Trees intercept precipitation, thereby reducing storm water runoff and improving water quality. 5. Trees provide shade and cooling and provide windbreaks, thereby reducing energy usage and air conditioning and heating costs. 6. Trees enhance habitat for desirable wildlife, providing a haven for birds, which in turn, assist in �--- control of insects. 7. Trees buffer different land uses to eliminate or minimize nuisances such as dust, litter, noise, glare, signs and unsightly building or parking areas. 8. Trees improve public health by reducing strees, encouraging exercise, calming traffic, decreasing illness recovery times, reducing crime, and improving concentration. 9. Trees attract residents, visitors, and commerce and increase the value and marketability of property. 10. Trees beautify the City and protect and enhance the quality of life. II.

A tree for tree replacement shall be required for each tree removed greater than 15 inches DBH, not to include Specimen Trees Trees selected shall be from the Milton approved tree species list. d. For the removal or destruction of trees on sites that currently meet the minimum TDU requirements, and removal will cause the site to fall below the minimum TDUs, the applicant shall provide mitigation to meet site density requirements by: 1. Replacing tree density through planting on the same property, or 2. Payment into the Milton Reforestation Fund for the lost density units as determined by the City Arborist. e. Notwithstanding any of the other requirements of this ordinance, it shall be unlawful to remove a specimen tree without a Tree Removal Permit issued by the City Arborist. Administrative standards have been established by the Director of Community Development for the identification, conservation and protection of specimen trees. B. Related to Development (Building Permit or LDP) All building permits and land disturbance permits shall obtain a Tree Removal Permit prior to the removal of any trees. Administrative Guidelines — Agriculture District -10- 1. An application for a Tree Removal Permit shall include a Site/Tree Conservation Plan or other documentation as required for review by the City Arborist for conformance to the provisions of these regulations and either approved, returned for revisions, or denied within 30 days of receipt. If denied or returned for revisions, the reasons for denial shall be annotated on the landscape plan or in writing. 2. Issuance of a valid Land Disturbance Permit shall indicate conformance to the provisions of these regulations. 3. Tree Removal is approved with an approved Land Disturbance Permit which must be visibly displayed on the site prior to and during any tree removal activities. 4. For issuance of any residential building permit, applicant must sign and agree to abide by the Residential Erosion and Sedimentation Control and Tree Conservation Agreement. This shall also apply to parcels upon which a land disturbance permit has been previously issued with a tree protection plan approved by the City Arborist. The Director of Community Development, City Arborist or designated agent(s) are authorized to execute such agreements on behalf of the City of Milton. C. Improvements to Parcels With Existing Structures Such as but not limited to pools, garages, decks etc. If the site meets density requirements and no trees are removed, no replacement trees will be required. 2. If the site meets or exceeds density requirements and tree removal will cause site to fall below density requirements, additional plantings will be required to satisfy density requirements. .--• 3.. If the site does not presently meet density requirements and no trees are removed, replacements will be required at the rate of one tree for every 200 sq.ft. of disturbed area up to, but not exceeding the density requirement for the site. 4. If the site does not presently meet density requirements and a tree or trees are removed, replacement will be required at the rate of one (1) tree for every tree removed plus (1) for every 200 sq.ft. of disturbed area up to but not exceeding the density requirement for the site. D. Timber Harvesting Requirements Agriculture (AG -1) Land Uses only Clear cutting or thinning for purposes of timber harvesting will require a Notice of Timber Harvesting Activity to be submitted to the City Arborist when more than 2 acres of land is clear cut or thinned. A permit will not be required, but the site tree density still has to be met. Clear cutting/timber harvesting is allowed on AG -1 zoned land only. Thinning is allowed in all zoning/land use categories. Clearing, thinning or disturbance is not allowed within state water or wetland buffers. Clear cutting is cutting trees down flush with the ground; stump removal is prohibited. Any portion of land clear cut or thinned under this provision is still required to meet the site density of 15 units per acre, which may require some planting of trees. Only properties zoned and used for bonafide agricultural activities will be granted approval for timber harvesting activities and shall comply with the following standards: 1. A Notice of Timber Harvest Activity form must be filled out in its entirety and submitted to the City Arborist. s,,," 2. A note stating that no stump removal or grading is allowed. 3. Any portion of land clear cut or thinned under this provision is still required to meet the site density of 15 units per acre, not including the 50 foot buffer, upon completion of the authorized timber %am harvesting activities. Administrative Guidelines — Agriculture District -11- 4. Erosion control measures as prescribed by the Soil Erosion and Sedimentation Control Ordinance. 5. Stream crossings as prescribed by the Soil Erosion and Sedimentation Control Ordinance. 6. A 50 foot undisturbed buffer shall be provided and maintained along the entire perimeter of the property, including road frontages, during and after the timber harvesting activity, except for authorized crossings. 7. No timber harvesting activities shall occur within the 50 foot State Waters buffer. All buffers are measured from the top of the bank on both sides of a stream or creek. 8. Violations of the State Waters buffer, tree protection areas, clearing without proper documentation may result in NO other permits for said site to be issued for up to five (5) years. NOTE: -Specimen trees will NOT be excluded and are to be protected with tree fence out to a distance of 3' beyond the edge of their root protection zone NOTE: Clear cutting will only be allowed in conjunction with a Land Disturbance Permit. It is the intent of this section that clear cutting is to be highly discouraged and allowed only by specific approval of a Land Disturbance Permit. SECTION 2 DENSITY STANDARDS The minimum tree density requirements for the site shall be maintained with existing trees or planting of additional replacement trees so as to produce a total site density factor for the required number of units for that particular zoning district. The required units for each district are shown in the table below: "AG -1" Agricultural 15 units per acre Single Family Residential 20 units per acre Commercial and All Other 30 units per acre Non -Single Family Residential If it has been determined by the City Arborist or designated agent(s) during the initial site visit that the property in question is completely barren of trees and has been for a considerable length of time (ie, pasture land), then the units for replacement trees will be doubled. (NOTE: the terms unit and tree are NOT interchangeable). Procedures for determining the site density requirements and the subsequent tree replacement requirements are provided in the next section. At least 70% of replacement trees must be hardwoods of at least 4 different species. SECTION 3 DENSITY CALCULATIONS Procedure for Calculating the Required Tree Replacement Density Factor. (Using the Single Family District as an example). Step 1 Calculate the density factor for the site (DFS) by multiplying the number of site acres by 20. EXAMPLE: A 2.2 acre site has a DFS of 2.2 x 20 = 44. Step 2 Calculate the existing density factor (EDF) of trees which will remain on site to be protected during construction. EDF is determined by converting the D.B.H. of individual existing trees to density factor units, using Table 1 These units are then totaled to determine the EDF for the site. "OW EXAMPLE: A total of 8 trees will remain on the 2.2 acre site. When converted to density factor units we calculate the following: Administrative Guidelines — Agriculture District '12' LqW_J TABLE 1 2 12" Pine 12" 3.2 X 2 = 6.4 on site. 2 14" Pine 14" 3.6 X 2 = 7.2 56.9 2 18" Oak 18" 4.0 X 2 = 8.0 8-10 1 20" Hicko 20" 4.0 X 1 = 4.0 1 30" Oak 30" 14.7 X 1 = 14.7 40 26.1 63 64.9 11-12 3.2 EDF 40.3 The sum total of units, 40.3, is the existing density factor EDF. 27.6 64 67.0 Step 3 Calculate the required replacement density factor (RDF) by subtracting the EDF (Step 2) from the DFS (Step 1) Example: 69.1 71.2 16.20 DFS -I EDF = RDF 30.3 66 67 73! 4 EE 21 4.8 44 31.8 45 33.0 68 75.6 44 - 40.3 1 =F170 LqW_J TABLE 1 EXISTING TREES TO REMAIN Conversion from D.B.H. to densi remamin factor units for treesr22.5 on site. 1.4 1.0 36 59 56.9 5-7 1.8 37 60 58.9 8-10 2.4 38 23.7 61 60:8 39 24.9 62 62.8 40 26.1 63 64.9 11-12 3.2 41 27.6 64 67.0 13`-15 3.6 42 28.8 65 69.1 71.2 16.20 4.0 43 30.3 66 67 73! 4 EE 21 4.8 44 31.8 45 33.0 68 75.6 22 5.2 46 34.5 69 111771.9 8.7 23 47 36.0 70 80.1 24 9.3 25 10.2 48 37.8 71 82.4 26 11.1 49 39.3 72 84.8 97 12.0'' 50 40.8 73 87.1 -13- Administrative Guidelines - Agriculture District 28 12.9 51 42.7 74 89.6 29 13.8 52 44.2 75 92.0 30 14.7 53 45.9 76 94.5 31 15.6 54 47.7 77 97.0 32 16.8 55 49.4 78 99.5 33 17.7 56 51.3 79 102.1 34 18.9 57 53.1 80 104.7 35 20.1 58 55.0 TABLE 2 REPLACEMENT TREES Conversion from caliper to density factor units for replacement trees. 1 0.40 8 1.30 2 0.50 9 1.50 3 70.60 10 1.70 4 0.70 11 1.90 5 0.90' 12 2.10 6 1.00 13 2.30 7 1.20 14 2.50 NOTE: Tree relocation: Replacement units may be granted to trees relocated on site. Tree relocation is subject to the City Arborist approval. ..- SECTION 4 STANDARDS FOR REPLACEMENT/RECOMPENSE TREES In order to qualify for tree replacement density credits, all over story replacement trees shall be at least two (2) caliper inches. All understory trees shall be at least six (6) feet tall planted and a trunk measurement of at least 1 '/2 caliper inches. It is the intent of this section that replacement/recompense trees be located on the project site for which the application has been received. Trees which cannot be planted on the project site shall follow the alternatives outlined in Section 7. A. TREE STOCK STANDARDS: Trees selected for planting must be free from injury, pests, disease or nutritional disorders. Trees selected for planting must be of good vigor. The determination of vigor is a subjective evaluation and depending upon species variability. The following criteria are generally used for the determination of vigor: 1. Foliage should have a green or dark green color. Vigorous trees will have large leaves and dense foliage when compared to trees with poor vigor. 2. Shoot growth for most vigorous trees will be at least 1 foot per year. At least '/z of the branches should arise from points on the lower 2/3 of a trunk. 3. Bark texture can denote vigor. Smooth or shiny bark on the trunk and branches of young trees usually signifies good vigor; conversely, rough and dull bark could indicate poor vigor. 4. Trunk taper: Trees with reverse tapers or no taper should be avoided. 5. Root color: young roots of most trees will be light in color. 6. Trees selected for planting must be free of root defects. Two types of root defects generally occur: a. Kinked roots, in which taproots, major branch roots, or both are, bent more than 90 degrees with less than 20% of the root system originating above the kink. A tree with such roots will probably bend at the soil line when released from a supporting stake. Administrative Guidelines - Agriculture District -14- b. Circling or girdling roots which circle 80% or more of the root system by degrees or more. A tree with such roots would ultimately have less than 20 percent of its root system available for support. B. RESPONSIBILITY FOR REPLACING PROTECTED TREE: The City Arborist may determine the time of replacement, and the location of the replacement trees and approve the agents responsible for replacing a wrongfully removed protected tree. The requirement to replace trees shall be binding upon the person subject to such an order or the record title owner. In the event of a sale, assignment, or transfer of property, the person subject to such order may either obtain the consent of the person to whom the property was sold, assigned or transferred to permit the replacement on such property, or may make payment into the Reforestation Fund as provided in this Ordinance. C. TIME OF REPLACEMENT: Any replacement trees required to be planted must be planted no later than ninety (90) days after the order of the City Arborist, or within thirty (30) days of the date of any appeal from such order becomes final, provided, however, that the City Arborist may require a deferral of the planting of replacement trees up to an additional one hundred eighty (180) days based outside planting season, and further provided that the City Arborist may, upon request of the person subject to the requirement approve delaying the planting of replacement trees up to an additional one hundred eighty (180) days if the person subject to the ordinance provides the city with a surety bond in an amount equal to the cost of purchasing and planting such trees or pay this amount into the Reforestation Fund within the earlier of the following (1) within 180 days of the last date approved for such delayed planting, (2) the date of issuance of the first certificate of occupancy on any portion of the subject property, or (3) other date as agreed by the City Arborist in an approved Tree Preservation Plan. The surety bond must be issued by company licensed to do business in the State of Georgia and shall be authorized by and approved by the City Attorney. D. LONGEVITY AND DURATION: If a replacement tree dies within two years from the date it was planted, the person subject to the requirement to plant the replacement tree must replace the dead tree with another 6W.- replacement tree within ninety (90) days of the order of the City Arborist ordering such replanting. The requirement to replace such replacement trees shall be binding upon the person subject to such order or the record title owner. In the event of a sale, assignment, or transfer of property, the person subject to such order may either obtain the consent of the person to whom the property was sold, assigned, or transferred, to permit the replacement on such property, or make payment to the Reforestation Fund as provided in the Ordinance. SECTION 5 SPECIMEN TREE STANDARDS Some trees on a site warrant special consideration and encouragement for preservation. These trees are referred to as "Specimen Trees". Trees unique due to age, size, species or historic relevance are to be identified during the survey process and special consideration shall be made to work around them. Cost effective building, site, hardscape and landscape designs will be strongly encouraged to conserve such specimen trees. These trees are to be identified and highlighted on the Tree Protection Plan. Design of buildings, hardscapes and utilities are to be developed with consideration to preserving and featuring specimen trees. Tree density unit credits are given for existing trees that are saved during the site development process, with greater credits given to specimen trees saved. 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 (2) times the assigned unit value. op" Specimen tree is any tree which equals or exceeds the following diameter sizes: %NO Large hardwoods 127" d.b.h. m, etc. Administrative Guidelines - Agriculture District -15- Large hardwood 24" d.b.h. Beech Large softwood 27" d.b.h. Pine Small native flowering 8" d.b.h. Dogwood, Redbud, Sourwood and a tree in fair or better condition must meet the following minimum standards: • A life expectancy of greater than 10 years • A relatively sound and solid trunk with no extensive decay or hollow, and less than 20% radial trunk dieback • No more than one major and several minor dead limbs (hardwoods only). • No major insect or pathological problem. • A lesser sized tree can be considered a specimen if it is a rare or unusual species, of exceptional quality, or of historical significance. • A lesser sized tree can be considered a specimen if it is specifically used by a builder, developer, or design professional as a focal point in a project or landscape. Specimen tree stands: A contiguous grouping of trees which has been determined to be of value by the City Arborist. Determination is based upon any one or more of the following criteria: • A relatively mature, even -aged stand. • A stand with purity of species composition or of a rare or unusual nature. • A stand of historical significance. • A stand with exceptional aesthetic quality. • A stand on a site which is otherwise devoid of trees fw w SECTION 6 SPECIMEN REMOVAL AND RECOMPENSE CALCULATIONS Any and all healthy specimen trees that the City Arborist allows a developer/builder/homeowner to remove must be compensated for. Specimen hardwood trees shall be compensated for with a mix of 2" and 4" caliper trees. (6" caliper trees may be required at City Arborist discretion). Specimen evergreen trees shall be compensated for with 4" caliper (and/or 6" caliper at City Arborist discretion) evergreen trees. Specimen native flowering shall be compensated for with either 2" or 4" caliper hardwood trees. Four (4) different species (minimum) of recompense trees shall be use if the number of recompense trees required is forty (40) or greater. For purposes of recompense trees ONLY, the unit value of a 2" caliper recompense tree will be .35 units, not its usual .5 unit value. Any and all specimen trees slated for removal must have their recompense trees bonded off prior to issuance of the Land Disturbance or Tree Removal Permit. If a specimen tree or trees are removed or their root protection zones disturbed without permission, the unit value of the specimen tree will be doubled and that becomes the unit value that must be recompensed. For example: a 30" DBH tree is normally worth 14.7 units. If it is removed or its root protection zone disturbed without permission, its unit value will double to 29.4 units. Thus 29.4 units must be replaced at the project site. Recompense trees cannot be used to satisfy any other landscape requirement such as parking lot shade trees, landscape strips, undisturbed buffers or detention pond buffers/landscape strip. Two inch caliper shade trees shall only be counted as .35 units per tree. (SIZE ALONE WILL DETERMINE WHETHER A TREE WAS OF SPECIMEN QUALITY IF THE TREE WAS REMOVED WITHOUT PROPER APPROVAL AND THERE IS NO EVIDENCE OF ITS CONDITION. IF A TREE HAS BEEN REMOVED ILLEGALLY AND DIAMETER CANNOT BE DETERMINED, THE DBH WILL BE DETERMINED BY THE DIAMETER AT THE EXISTNG STUMP). SECTION 7 ALTERNATIVES TO REPLACEMENT/RECOMPENSE PLANTINGS MOWN A. TREE BANKING: Arrangements must be made through the City Arborist if the Tree Bank alternative is to be utilized for the development. Tree Banking will be considered after design alternatives which could save more existing trees have been evaluated and reasonably rejected. All tree bank trees are to be guaranteed Administrative Guidelines — Agriculture District -16- Wow for 2 full years after planting by the developer. Any trees that die within this time period must be replaced by the developer. "`" B. STANDARDS FOR REPLACEMENT STOCK: (See Section 5) C. LOCATION: Trees that cannot be planted on the project site as required may, with approval from the City Arborist, choose from the following altenatives. 1 Replacement on public property 2 Replacement on other private property within the City of Milton, with the approval from owners of both the property from which the tree was removed and the property on which the replacement is to occur, shall agree, in writing, to maintain the replacement tree(s) to the standards established in this Ordinance. 3 Payment to the Reforestation Fund as provided below. D. REFORESTATION FUND_ The Reforestation Fund is another alternative to help an applicant meet the tree density or tree recompense requirements. All payments into the Reforestation Fund shall be used for the purchase, installation and maintenance of trees on private property when approved by the City Arborist and the Director of Community Development, on public property, and for the acquiring of wooded property which shall remain in a naturalistic state for the benefit of the community. Funds must be tracked so they can be identified for their intended use. In addition, these funds shall be reserved so that at the end of each fiscal year, any unspent funds will be considered Reserved Funds for this specific purpose and will be available in the subsequent years for their intended purpose. �••. 1. Tree replacement cost estimates obtained from three (3) landscape contractors must be provided to the Milton City Arborist for approval and the tree replacement cost will be based on an average of the three estimates. 2. The required replacement fee will be 125 percent (%) of the total cost to plant and establishment/maintenance costs for the balance of trees that were unable to be planted to satisfy the site density requirement or recompense tree requirements. Species selected for quote estimate must be grade "A" quality, healthy trees. SECTION 8 METHODS A. PLANNING CONSIDERATION Root space is the most critical factor in tree protection throughout the development process. The root system of trees easily goes beyond the drip line of the tree canopy. Disturbance within the root zone can directly affect a tree's chance of survival. To protect the root zone, the following standards shall apply: 1. The use of tree save islands is encouraged rather than the protection of individual trees (non -specimen) scattered throughout the site. This will facilitate overall site organization as related to tree protection. 2. The root protection zone of specimen trees, heritage trees, undisturbed buffers, stands of trees or otherwise designated tree save areas shall include no less than the area of a circle with a radius that extends one foot out for every inch of trunk diameter, or the area of a circle with a radius extending from a tree's trunk to a point no less than the end of a tree's longest branch, plus 3 feet, WHICHEVER IS am" GREATER. In some instances, the City Arborist or authorized agent(s) may require an additional area of non -disturbance up to 10 feet outside the root protection zone. Administrative Guidelines — Agriculture District -17- „w,,,, 3. Tree preservation and grading requirements are two design constraints, which are most often in conflict. A grade change of a few inches can be detrimental to a tree, yet most sites require extensive R. cut and fill in order to manage drainage. The use of berms or retaining walls, instead of cutting, to provide detention can be used to preserve significant trees. Detention ponds can be designed around significant trees by adding depth to minimize width where possible. Retaining walls can also be used to mitigate cut and fills. 4. Underground water and wastewater lines, storm sewers, irrigation lines, both underground and overhead electric and telephone lines can have a considerable impact on trees. The layout of the project site utility plans shall accommodate the required tree protection zones. Utilities shall be placed along corridors between tree protection zones. Developers shall coordinate the location of utility lines, including irrigation and electric lighting, with the utility companies in order to prevent root damage within the critical root zones of protected trees and to minimize damage to trees located in protected zones. 5. Sidewalks and alternative walkways can often appear innocuous on plans, but can be very detrimental to trees due to grading requirements. Consideration should be given to move sidewalks and alternative walkways as far from tree trunks as possible and provide a finished grade above the existing grade for sidewalks required in close proximity to a tree trunk. Drainage can be routed under sidewalks and alternative walkways where an elevated grade is required. B. PROTECTIVE MEASURES The root system within the drip line is generally considered to be the critical root zone. Most trees can pw� tolerate only a small percentage of critical root zone loss. To protect these critical root zones, a tree protection area shall be established around each tree or group of trees to be retained. The following section describes ways to help control unnecessary encroachment on existing trees. These methods and "”' guidelines will be followed for tree protection throughout all phases of construction. These guidelines are designed to reduce damage to critical root zones and wounds to expose roots, trunks, and limbs by chemical, mechanical, or other means. Tree protection areas shall be delineated on the Tree Preservation Plan and methods shall be clearly noted and detailed. 1. ACTIVE PROTECTIVE BARRIERS - Barriers shall be installed along the outer edge of and completely around the critical root zone of all specimen trees or stands of trees, or otherwise designated tree protection areas, prior to any land disturbance. Deviations from this must be approved on an individual basis by the City Arborist. Barriers shall be minimum four (4) feet high, orange polyethylene laminar safety fencing. All tree protection zones shall be designated as such with "Tree Save Area" signage posted visibly throughout the site. All tree fencing shall be maintained throughout all land disturbance and building construction, and should not be removed until all construction and landscaping is complete and approved by the City Arborist. Upon completion of the project the tree fencing must be removed. 2. SIGNAGE — All tree protection fencing must be accompanied by "STAY OUT —TREE SAVE" signage. Tree protection signs may be purchased at the City of Milton Community Development Department. 3. BORING — Non open trenching will be allowed within the protected zone as defined by the protective barricades. All underground utilities to be installed within this protection zone shall be installed by boring underneath the root zone. Any exceptions must be approved by the City Arborist. Utilities may be tunneled in the root zone at a thirty-six (36) inch minimum depth providing that plans are approved showing the location and method. 4. FILLING (CLEARING WITHIN ROOT ZONE —Fill dirt no deeper than two (2) inches may be allowed " within the drip line of the tree. No grubbing is permitted in the root zone. In the protected root zone, Administrative Guidelines — Agriculture District -18- any stumps, dead trees and shrub growth to be removed shall be cut flush or ground out. Stump grinding will be accomplished with equipment and methods acceptable in normal arboricultural laws operations. All holes will be backfilled completely the same day of the operation. 5. SOIL COMAPACTION- Where compaction might occur due to traffic or materials storage, the tree protection zone must be mulched with a minimum four (4) inch layer of shredded hardwood mulch. 6. CLEARING ACTIVITIES — Roots often fuse and tangle amongst trees. The removal of trees adjacent to a tree save area can cause inadvertent damage to protected trees. Wherever possible, it is advisable to cut minimum two (2) foot trenches (e.g. with a ditch witch) along the limits of land disturbance, so as to cut, rather than tear the roots. Trenching may be required for the protection of specimen trees. The cutting down and then grinding the stump of the adjacent removed trees, as opposed to bulldozing them and ripping their roots, can also aid the protected trees. 7. TREE REMOVAL — To minimize potential root loss from soil disturbance in an overlapping root situation, all roots attached to a tree inside a tree save area that extends outside the tree save area shall be cut by hand if the soil is to be disturbed. The removal of any tree adjacent to a tree within a tree save area shall not be removed by heavy equipment. Cutting the roots by hand or with a ditch witch is acceptable. SECTION 9 LANDSCAPE STRIP AND BUFFER STANDARDS A. Landscape Strips 1. The width of landscape strips must, as a minimum, conform with the requirements of the conditions of lv" zoning or the requirements of the Zoning Resolution,. The width is measured from the newly dedicated right-of-way, or from the property lines of contiguous parcels, as applicable. 2. No permanent structures are permitted within landscape strips. This includes, retaining walls, curbing, dumpsters, detention facilities, etc. Monument signs, fences,drainage structures, and sidewalks may be allowed with pre -approval. 3. Curb stops must be used to prevent vehicle overhang into required landscape strips and parking lot landscape islands. One curb stop per parking stall is required. 4. Signs within required landscape strips are subject to the approval of the Department of Community Development or designated agent(s). These signs may only be located in areas of turf or groundcover and must not conflict with the growth potential of trees and shrubs. Signs are not permitted within required undisturbed buffers. 5. The deposition of storm water runoff into drainage swales through landscape strips is generally not permitted. Exceptions will be considered only if this standard will create an undue hardship to the property owner. Unless approved by the City Arborist the width of a drainage easement through a landscape strip shall not exceed the width of the strip. 6. Parking lot landscape islands must, at a minimum, conform to the requirements of the Zoning Resolution. These islands must be planted with at least one 2 inch caliper (minimum) shade tree. Stormwater runoff into parking lot landscape islands may be permitted upon approval by the City Now Arborist. Administrative Guidelines — Agriculture District -19- *..•r 7. When fencing is required as a condition of rezoning, the finished surface of the fence must face externally to the project. The exact location for fence placement within the landscape strip will be determined on a case by case basis by the City Arborist or designated agent(s). 8. All species within required landscape strips must be ecologically compatible with the intended growing site. If ornamental trees are used to satisfy landscape strip requirements, they will not count for satisfying tree density requirements. All plant materials are subject to Department of Community Development or designated agent(s) approval. 9. Trees within required landscape strips shall be provided as follows: a. Landscape strips 25 feet wide or less; a minimum of one tree for every 30 linear feet of landscape strip. b. Landscape strips 25 feet wide or more; a minimum of one tree for every 20 linear feet of landscape strip. C. Clumping is permitted. All required landscape strips must be designed with at least 60% coverage in trees and shrubs, with no more than 40% coverage in grass or ground cover. Landscape strip coverage will be calculated as follows: a. Calculate the total spatial area of the landscape strip. b. Count the number of trees within the landscape strip and multiply by 100 square feet for trees less than 6" caliper and 200 square feet for trees 6" or greater (This will allow some credit for the spatial coverage of the tree canopy) c. Calculate the coverage provided by the shrubs planted on center: ON CENTER Equals COVERAGE PER SHRUB *3 feet = 9 square feet *4 feet = 16 square feet *5 feet = 25 square feet *At maturity, shrubs must attain this width. Shrub species and spacing is subject to arborist's approval. d. Grass or ground cover may not exceed 40 %coverage within the strip. PLANTINGS IN RIGHT-OF-WAY Approval from Community Development, Public Works and the Department of Transportation (D.O.T.), where applicable, is required, as planting is generally not permitted in the right-of-way. Where approval is received, the following conditions must be met: 1. Indemnification and maintenance agreements must be recorded with the Fulton Superior Court Clerk prior to permitting irrigation or planting in the right-of-way. The City shall be held harmless if damage to irrigations systems or vegetation should occur within the right-of-way. 2. These agreements must be recorded in the name of a homeowner's association (along with ,p,,,„ documentation attesting to that association's existence), for subdivisions. 3. These agreements must be recorded in the property owner's name for all other types of projects. *No Administrative Guidelines — Agriculture District -20- Opuft 4. Trees planted within right-of-way will not be counted toward the density requirement for a site unless approved by the City Arborist and Public Works. ONO 5. Prior to planting trees in right-of-way, a typical cross-section must be provided indicating the placement of the trees in relation to the curb, and underground utilities. Placement and species are subject to the approval of the City Arborist and Director of Public Works. 6. Drawings for irrigation system within right-of-way must indicate the location of lines, heads, sprays radius, shut off valves, timers and a 24 hour emergency contact phone number. 7. The city shall have the right to plant, maintain, prune, and remove trees, shrubs, and plants within the right of way of all city streets, roads, and highways, in parks, around city facilities, and on other city grounds, as may be necessary or desirable to ensure public safety, to preserve tree health, and to maintain and increase tree canopy. 8. It shall be unlawful for any person to engage in any activity on private property that directly or indirectly adversely affects the health or condition of a tree on city property. If a person damages, destroys, or fails to protect a city tree, the city may require replacement and/or payment of a fine up to $1,000.00. C. BUFFERS 1. Required undisturbed buffers must remain undisturbed and actively protected for the duration of such permitted use for the site. Buffers must be replanted where sparsely vegetated or where disturbed for approved access and utility crossings. The buffers should be replanted to meet the following standards: C. Must provide a visual barrier. To accomplish this screening, the plant materials must be a minimum 5 feet in height at time of planting, moderately slow growing evergreen and have branching all the way to the ground. All buffer plant materials are subject to the City Arborist or designated agent(s) approval. d. The number of planting rows for tree replacement in buffers is determined by the buffer width: e. Drainage within or through buffers is subject to the approval of the Community Development Department. f.

Arborists certified by the International Society of Arboriculture have teswd to insure a minimum level of arboricultural competency and maintain their certification with continuing education. Arborist should follow ANSI A-300 Standards for Tree Care Operations. b. The objectives for tree pruning should be estabiished prior to commencement of pruning activity. 'frees should never be "topped'. Topping a tree permanently damages a tree's structure. Destroys its value, damages its health, and decreased the tree's safety. d. Climbing spikes should never be used to prune a tree. e, Always prune branches back to parent branches at least 1113 the diameter of the branch being pruned. f. No more than A of the foliage of a mature tree should be removed in any one growing season. g. Make proper pruning cuts, using the three cit method. Avoid stub cuts and wounds to the remaining limbs and trunk. h. Pruning cuts should be made just on the outside of the branch collar. t. At the time of planting, prune only dead, damaged, broken, crossing, or rubbing branches. i. Do not remove more than 1/3 of the foliage from a young tree during any one growing season_ 2. Tree Mulch a. "free mulching is vers beneficial to trees because it helps retain soil moisture, moderates soil temperature, suppresses weed growth, reduces soil compaction, and reduces the potential for mower and string trimmer damage to trees. b. Use organic materials such as pine straw, leaves, aged wood chips (3 months), and compost_ Avoid 4WWW grass clippings, plastics, and roc]cS. Use trees ownfail::^n leevesfor mulch. d. Spread mulch in an even layer, 3-4 inches deep. Avoid mounding the mulch around the tree's trunk- Now Xeep mulch at least S inches from tree's trunk. f. For newly established trees, mulch area at.least6 feet in diameter. g. For older established trees, mulch out as far as practical, mulching to the drip line is most raesira'rlt�. f erti liza tfrn Trees that are in an urban grovring environment •.vith limited nutrient cyt:lin.gsi:cuid be fertilized on a regular (every 3 to 5 year) schedule. b. if trees are exhibiting symptoms of nutrient deficiency, soils 51tculd be tested prior to fertilization, and. the fertilizer formulation should be adjusted to address the specific deficiency. !ewjy planted, drought stressed or severely damaged Or injured : ees should not be fertilized. d. `Fertilizer Should be applied when roots are actively gro:ving.
