Arborist report means a report prepared by an arborist containing specific information on the location, condition, potential impacts of development, recommended actions and mitigation measures regarding one or more trees on an individual lot or project site.

Certification letter means a concluding statement by an arborist stating that work that was performed by an arborist or was observed or inspected by an arborist and complies with the conditions of the arborist report, and the tree permit or conditions of project approval.

City Tree means any woody, perennial plant, regardless of size, located in a city park, a designated open space, or on any other city property. A single or multi-stemmed shrub or bush is not a city tree.

Conforming Use means permitted uses that conform to the development criteria of the zoning district for the site.

DBH means the diameter of the tree at breast height and is measured across the widest face of the tree trunk, 4½ feet above natural grade. On a slope, the four and one-half-foot height is measured from the center of the trunk, halfway between the uphill and downhill side. In the case of multiple stemmed trees, the measurement is the sum of the diameters of the three largest stems measured at 4½ feet above natural grade.

Dead Tree means a tree that is dead or that has been damaged beyond repair or is in an advanced state of decline (where an insufficient amount of live tissue, green leaves, limbs or branches exists to sustain life) and has been determined to be such by a certified arborist, landscape architect or city official.

Dripline (canopy dripline) means the diameter of the existing tree canopy, or the estimated diameter of the root system (calculated as DBH inches × 2 feet) whichever is greater.

Excessive Pruning means removal of the leaf, stem area, predominately on one side, topping, or excessive tree canopy removal or crown raising. Exceptions are when clearance from overhead utilities or public improvements is required, or to abate a hazardous condition or public nuisance.

Principal Native Tree means a Coast Live Oak, Valley Oak, Redwood, Madrone, Bay Laurel, or Buckeye having a single main stem or trunk of 10 inches or more DBH, or up to three of the largest secondary stems totaling 10 inches or more DBH.

Large Diameter Tree means a woody, perennial plant characterized by having a single main stem or trunk of 14 inches or more DBH, or up to three of the largest secondary stems totaling 18 inches or more DBH.

Person means any natural person, property owner, partnership, firm, corporation, governmental agency or other legal entity other than the City of Belmont.

Protected Tree means a Principal Native Tree, a City Tree, a Replacement Tree, a Right-of-Way Tree, or a Large Diameter Tree.

Pruning means selectively cutting or trimming to enhance the health and structure of a tree, improve balance and aesthetics, promote healthy growth, and prevent damage.

Removal means physically removing a tree or causing the removal of a tree; causing the death of a tree through direct or indirect action, or severely damaging a tree.

Replacement tree means any tree, regardless of size, which has been planted as required mitigation for the previous removal of another tree at the same site or elsewhere in the city.

Right-of-Way Tree means a tree located in a public street right-of-way.

Severe Damage means any action undertaken which causes or may cause death or significant injury to a tree or its roots, or which places the tree in an irreversible state of decline. This includes, but is not limited to:

(1) Excessive pruning as herein defined;

(2) Topping, which generally means reduction of tree size using inter-nodal cuts without regard to tree health or structural integrity;

(3) Trenching, excavating, grading, paving or other action which causes a significantly harmful incursion within the root system or canopy drip-line of a tree;

(4) Poisoning, or leaching of construction related or other damaging materials into the canopy dripline;
