1. Protective Fencing.
a. Continuous fencing consisting of a bright orange plastic mesh at least four feet high shall be provided along the driplines of trees to be retained for credit towards any Ordinance requirements (see Figure 5.9.5: Tree Protection Devices).
b. Retained trees that are inaccessible to development activities or separated from all development activities by a distance of at least 300 linear feet are exempted from the requirement for tree protection fencing.
2. Warning Signage.
a. Warning signs shall be installed along any required tree protective fencing.
b. The signs shall be clearly visible from all sides around the outside of the fenced-in area.

D. Tree Protection Requirements.
1. No development activity—including grade changes, the operation or parking of heavy equipment, or the washing down of concrete or cement handling equipment, or the storage of fuel, chemicals, materials, supplies, or construction waste and debris—shall be allowed within areas surrounded by tree protection fencing.
2. No structures or hard surfaces shall be located within areas surrounded by tree protection fencing.
3. Retaining walls and drywells may be used to protect trees to be preserved from severe grade changes if venting adequate to allow air and water to reach tree roots is provided through any fill.
E. Damage or Death of a Protected Tree. If a violation of this section occurs and a protected tree is removed or dies within two years after a certificate of occupancy is granted for that portion of a development where the tree is or was located, then the landowner, owners' association, or occupancy permit recipient, or their successor, as
appropriate, shall be required to install replacement trees at the rate necessary to re-establish the tree canopy coverage requirements.

A. Open Space Set-Aside. Land area devoted to reforestation or to the retention of existing trees during and after development activity shall be credited towards any passive open space set-aside requirements in Section 5.7.4, Minimum Open Space Set-Aside Requirements.

A. Reforestation and tree retention areas are intended to remain undisturbed by clearing or development. Any disturbance of these areas shall be a violation of this Ordinance in accordance with Article 8: Enforcement.
B. Trees located within reforestation or tree retention areas are intended to remain until their natural death. In the event of disease or the creation of an unsafe situation, the Planning Director may allow selective clearing or removal of trees subject to an approved replanting plan.(Ord. 2020-36, passed 12-2-2019)
These standards are intended to reduce the visual and auditory impact upon adjacent lots and the public realm from certain site features and activities occurring on individual nonresidential, multi-family and mixed use lots. In addition to mitigating negative impacts, these standards are also proposed to enhance the aesthetics of development in the Town's planning jurisdiction.
