General requirements.
The site plan shall include a tree survey identifying the size, species and location
of all trees having a diameter at breast height (DBH) of six inches or greater. Such
site plan shall contain topographic information at two-foot contour intervals and
shall show all existing and proposed buildings and structures, driveways and parking
areas, drainage structures, water detention areas, utilities, construction material
staging grounds and all areas of required cut and fill. Single family lots of record
may be exempt from the requirement of the topographic survey provided that no grading
or cut or fill or other changes in topography will occur. Such plan shall denote each
tree to be saved, lost or destroyed, the percentage of root save area that will be
impacted, the required tree protection fences for trees to be saved, and the proposed
tree replacement plan. The proposed tree replacement plan shall set forth the manner
in which the newly planted trees will be watered, for example, manually, drip irrigation,
Gator bags, etc. In addition, the proposed tree replacement plan shall have attached
a copy of a paid maintenance contract if applicable. Pines of less than 12 inches
DBH are exempted from being denoted on the tree survey. A construction limit line
shall be delineated on each site plan submitted for a building permit. Within the
construction limit line, the tree replacement requirements of this article shall be
shown. Outside this limit line, no tree survey shall be required, and the applicant
shall be required to leave undisturbed all areas of trees.
(b)
Boundary trees.
Boundary trees shall be included in the site plan. The on-site portion of the root
save area of a boundary tree shall be enclosed in a tree protection fence according
to established arboricultural standards. In consultation with the owner or owner's
representative of a boundary tree, the city arborist may prescribe and the applicant
shall institute additional protective measures to limit impact on the tree during
construction, including but not limited to watering regimes, root treatments, mulching,
deadwood removal and protective pruning.
