(Ord. 5309 §1 (part), 2016: Ord. 4553, Repealed & Replaced, 06/20/1996)
13.10.080 PLANTING, PRUNING, REMOVAL, AND MAINTENANCE STANDARDS.
The following standards are hereby established for the planting, pruning, removal, and maintenance of municipal trees and shrubs in the public areas of the City. All planting of trees and other landscaping in public areas of the City, including the rights-of-way, shall be in conformance with the City’s engineering design and construction standards:
(a) Planting.
(1) All trees will be not less than one and one-half (1-1/2) inch caliper and be No. 1 grade, as described by the American Association of Nurserymen (AAN).
(2) Soil amendments, in accordance with the Stormwater Manual in BMC 15.04.020, shall be provided in all planting areas prior to planting.
(3) No tree or shrub will be planted closer than two (2) feet from the curbline or ten (10) feet from a driveway or alley. Trees shall be spaced at intervals of at least twenty (20) feet depending upon species and the expected height of the tree at maturity. Plantings at or near intersections shall be spaced in accordance with sight distance specification in the City’s engineering design and construction standards.
(4) Sidewalk cuts, where necessary, shall be approved by the Engineering Division and will be a minimum of four (4) feet in diameter so as to allow the natural percolation of water. Paver blocks, cobblestones or tree grates or other permeable surfaces will be used to fill the sidewalk cuts around trees.
(5) All young trees, for a minimum of one (1) year, shall be securely staked and guyed until the roots become established.
(6) Municipal trees and shrubs planted prior to the passage of the ordinance codified in this section are exempt from these planting standards.
(7) A list of recommended species of municipal trees is available from the Parks and Recreation Department for those desiring to plant municipal trees in City areas adjacent to their properties. Approval of the tree species is required by the City Arborist prior to planting, if it is not on the recommended species list.
(8) Public education programs regarding tree planting, care and maintenance will be provided by the Parks and Recreation Department in conjunction with Arbor Day festivities each year in April to encourage public involvement in tree planting. Additionally, the Parks and Recreation Department will maintain a tree library available for use by the public.
(b) Pruning. Pruning of any municipal tree on any public area must be authorized by the Parks and Recreation Department’s City Arborist or performed by City employees at the discretion of the Department. Trees are pruned to preserve their health and appearance, and to eliminate safety and utility concerns, which will increase their longevity in the urban area.
(1) Pruning Defined.
(i) Fine pruning: removal of dead, diseased, objectionable and/or weak branches which are larger than one-half (1/2) inch in diameter.
(ii) Medium pruning: removal of dead, diseased, objectionable and/or weak branches which are larger than one (1) inch in diameter.
(iii) Safety pruning: removal of the dead, diseased and/or weak branches to a size that in falling would injure a person and/or property.
(iv) Cut back to topping: cutting back, drop crotching or topping consists of the reduction of tops, sides, underbranches, or individual limbs with attention given to symmetrical appearance.
(2) All trees and shrubs which have branches overhanging a public street or boulevard shall have said branches pruned to a clearance height of fourteen (14) feet. Those overhanging a public sidewalk shall be pruned to a clearance height of eight (8) feet. The provisions of this section may be waived by the Parks and Recreation Department in the case of newly planted trees so long as they do not interfere with public parking, travel or safe viewing distances at intersections, or endanger public safety as determined by the Engineering Division. Any tree or shrub on private property which hangs over a city right-of-way which is not pruned as herein provided shall be subject to the provisions of BMC 13.10.090.
(3) All dead wood, stubs, broken branches, badly formed branches, diseased branches, and branches interfering with public travel, lighting, existing buildings and traffic signs, shall be removed during the pruning operation, with consideration given to the symmetry and beauty of the municipal tree or shrub.
(c) Removal.
(1) All municipal trees and shrubs which have fallen or been authorized for removal shall be completely removed from the growing site and disposed of in an authorized manner. The stump shall be ground out to a depth suitable for future planting of trees or turf.
(2) When municipal trees or shrubs are removed because of inappropriate location, a more appropriate site for replacement will be selected, when possible, in as close a proximity as spacing permits. Trees removed due to health, age, size for its location, or undesirable species type shall be replaced, when appropriate/available, with a suitable tree or shrub which will not produce the same problem in accordance with this section.
(3) No municipal tree or shrub shall be removed from any public area for the sole purpose of providing a view for any private property or individual.
(d) Maintenance.
(1) All municipal trees will receive routine maintenance on a four (4) year cycle.
(2) Special consideration will be given to the watering, weeding and protection of young trees during the first three (3) years.
(3) The use of biological controls and sprays will be encouraged and used by City employees whenever possible in the treatment of insect infestation in trees on city lands and rights-of-way.
(4) Preserve and maintain park soils for long-term tree health. Protect soils from compaction, allow plant debris or its equivalent to be left on the soil surface to replenish organic matter, and reduce chemical inputs to soil, where possible. For lawns and high-nutrient-demand landscapes, consider adding one-quarter (1/4) to one-half (1/2) inch of compost raked into landscape in spring or fall.
