NOTE: Other trees may be approved on a case-by-case basis. The general criteria for replacement trees to be used in Tree Density Calculations are large growing (35’– 40’ tall or taller at maturity) and long-lived. All planting plans are subject to the City Arborist or the Department Community Development designated agent(s) approval.

Required DFS (density factor for the site) is calculated as follows based on the applicable district.

EXAMPLE: Using the Commercial District density - DFS = 5 acres x 30 units = 150 units required.

Other species may be acceptable as long as they produce dense, full canopies at maturity and can develop sufficient root systems in confined spaces. Under no circumstances will upright, columnar, or fastigiate trees be acceptable as parking lot shade trees.

Site Plan Minimum Guidelines

Other Minimum Guidelines Timber Harvesting under this provision shall comply with the following guidelines:

NOTE: Concerning the best management practice of SMZ’S or stream side management zones, no timber harvesting can occur within the 25-foot State Waters Buffer, the 50-foot blueline Tributary Buffer, or the 75-foot State Waters Buffer. All buffers are measured from the top of the bank on both sides of a stream or creek that has been delineated by City of Johns Creek as State Waters.

NOTE: Large Pine Trees 24” d.b.h. or greater shall be excluded from specimen tree protection requirements in timber harvesting operations on AG-1 zoned land. Specimen hardwood trees, however, will not be excluded and are to be protected with tree fence out to a distance of 3 feet beyond the edge of their root protection zone.

NOTE: Refer to Appendix I. to complete the Residential Erosion & Sedimentation Control & Tree Protection Agreement Form.

Tree Type Tree Diameter Size Examples Large hardwoods 27" d.b.h. Oak, Hickory, Yellow Poplar, Sweetgum, etc.

Large hardwood 24" d.b.h. Beech Large softwoods 24" d.b.h. Pine, Deodar Cedar Small Native Flowering 10" d.b.h. Dogwood, Redbud, Sourwood A tree in fair or better condition must meet the following minimum guidelines:

Specimen Tree Stands means a contiguous grouping of trees which has been determined to be of value by the Director of Community Development or Authorized designee(s). Determination is based upon any one or more of the following criteria:

Utilities must be placed along corridors between protective zones.

NOTE: Unless enough existing trees are saved on site to satisfy density requirements, proposed replacement trees will have to be bonded off prior to issuance of the Land Disturbance Permit.

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 long time (i.e. pastureland), then the units for replacement trees will be doubled. (Example: a 4-inch replacement tree is currently equivalent to 0.7 units at a site determined to be barren of trees, the replacement units will be equivalent to 1.4 instead of 0.7 units.) The site will still be required to meet the appropriate tree density factor based on the applicable district –Agricultural, Single-Family Residential, or Commercial and all other Non-Single-Family district unit measurement.

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 Table 1.0 and Table 2.0 in the next section. No more than 30% of the replacement trees can be pines. At least 70% of replacement trees must be hardwoods of at least 4 different species.

Specimen native flowering trees must be compensated for with either 2” or 4” caliper hardwood trees. Four

If a specimen tree or trees are removed without permission or the City Arborist determines that the damage to the root protection zone of a specimen tree results in a specimen tree having less than a 50% chance of surviving for two (2) years, the unit value of the specimen tree is doubled and that becomes the unit value that must be compensated for. 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 of 2” or 4” caliper trees will have to be replaced at the project site. Recompense trees cannot be used to satisfy any other landscape requirement such as parking lot shade trees, landscape strip, undisturbed buffer or detention pond buffer trees. They can, however, count toward the required tree density for the site. 2” caliper recompense trees that are counted for density will be worth .35 units per tree.

If the root protection zone of a specimen tree is disturbed without permission, and the City Arborist has determined that the tree has a greater than 50% chance of surviving for two years, and the violator has submitted an acceptable prescription for continued maintenance of the endangered tree, then 50% of the unit value of the specimen tree is the unit value that must be compensated for. The recompense generated shall be divided equally with 50% of the recompense amount deposited into the Tree Replacement Fund and 50% of the recompense amount deposited into an escrow account. The half deposited into the Tree Replacement Fund is forfeited as restitution for the encroachment of the root protection zone; the half deposited into the escrow account shall be returned to the violator after a period of two (2) years with the submittal and acceptance by the City Arborist of an affidavit by the certified arborist certifying that the tree has not declined beyond the natural aging process or that no other decline has occurred which could have been prevented by the property owner. The violator will have one (1) year following the end of the aforementioned two (2) year period to make application to the City for fund deposited into the escrow account. In the event no application is made within the one (1) year period, the amount placed in escrow will be forfeited to the Tree Replacement Fund.

WHEN THE OWNER/DEVELOPER/CONTRACTOR CALLS THE LAND DEVELOPMENT DIVISION (678)

512-3200 FOR A FINAL INSPECTION, THE OWNER/DEVELOPER/CONTRACTOR SHALL INFORM THE ARBORIST THAT THE SITE VISIT INCLUDES A SITE VISIT TO A PUBLIC PROPERTY TO INSPECT TREES THAT HAVE BEEN TREE BANKED.

ANY CHANGES IN TREE VARIETY MUST BE APPROVED IN WRITING BY THE CITY OF JOHNS CREEK LAND DEVELOPMENT DIVISION AT (678) 512-3200.

PLANTING MUST BE COMPLETED BY THE OWNER/DEVELOPER AND THE PLANTING MUST BE INSPECTED AND APPROVED BY THE CITY OF JOHNS CREEK ARBORIST PRIOR TO THE ARBORIST’S SIGN-OFF ON THE CERTIFICATE OF OCCUPANCY OR FINAL PLAT RECORDING FOR THE PROJECT.

EXAMPLE: DFS = 2.2-acre site x 15 units per acre (Agricultural district) = 33.
