§ 35-B123. Tree Permit—Tree Preservation Plan Option.
(a)
Number of Copies. The applicant shall submit a tree preservation permit application with three (3) sets of tree preservation plans, a survey showing the location of all significant, heritage, or mitigation trees, including clusters, an inventory with calculations, and tree protection notes as provided herein. The applicant shall also provide a Habitat Compliance Form consistent with section 35-B133, as applicable.
(b)
Format. The tree survey shall be drawn to scale with sufficient clarity to indicate the location and extent of the work proposed, and show in detail that it conforms to the requirements of this section. The survey shall be submitted on a tree preservation (TP) sheet(s) and shall relate to the civil drawings. A survey that cannot be drawn on a single sheet shall be drawn with appropriate match lines on two (2) or more sheets. A TP survey sheet may also include the tree inventory, calculations, and the tree protection notes at the discretion of the applicant. It shall be the responsibility of the permit holder to maintain a copy of the tree permit, the data and drawings required by this section, and the conditions of approval imposed by the city arborist readily available at the site at all times during which the authorized work is in progress. All tree preservation plans shall be submitted in the form required by the city arborist and shall contain and provide tree protection notes, details and specifications clearly indicating the trees which will remain and the trees which are to be removed.

Contents.
(1)
The tree preservation plan contains three (3) components: a tree survey, the tree inventory, and the tree protection notes.
A.
Multi-family residential, commercial and other development:
1.
The Tree Survey. The tree survey shall, at a minimum, provide the following:
i.
A vicinity map, project name, street address (or plat #, parcel #, or legal description), date, scale, north arrow and the names, addresses and telephone numbers of the person(s) preparing the plan;
ii.
The location, species and size in diameter inches of each significant, heritage, (see subsection 35-523(f)) or mitigation trees, and any cluster or natural areas used to meet the requirements within the project area. Each tree is to be given a unique number which cross references or identifies the trees in the inventory. Warranty trees are to be clearly labeled on plan and inventory;
iii.
The location of property lines, existing site grades and proposed site grades, location and width of existing and proposed streets and alleys, utility easements, driveways, parkways, and sidewalks on or adjacent to the project;
iv.
Approximate centerlines of existing watercourses and the location of the 100-year floodplain; approximate location of significant drainage features and any major topographical features; including environmentally sensitive areas such as steep slopes, regulatory floodplain or riparian buffers with the applicable sixty- or thirty-foot preserve area;
v.
The location and dimensions of all staging areas and/or designated parking areas for the parking and maintenance of all vehicles, trailers, construction equipment, and related items as well as stockpile areas for the storage of construction supplies and materials; and
vi.
The location of all improvements and their proximity to significant or heritage trees.
2.
The Tree Inventory. A tree inventory shall include:
i.
The diameter inches of and species of each significant, heritage, (see subsection 35-523(f)) or mitigation trees and optional cluster trees; tree number, species, DBH, location, and disposition of each tree;
ii.
Reasons for removal of any such trees;
iii.
Calculations indicating total diameter inches, inches preserved, and percent preservation, with a delineation of significant and heritage trees;
iv.
The tree designation (significant or heritage tree) and desirability percentage; and
v.
The tree planting designation (quantity, size and type) and desirable location.
3.
The Tree Protection Notes. The tree protection notes shall include written information containing acceptable activities on the site and within the root protection zone of each tree, cluster or natural area to be preserved to meet the requirements for this standard, including:
i.
Details and graphics illustrating the protective measures such as fencing and alternative construction methods; and
ii.
Specifications denoting the criteria for methods and materials used for tree protection.
B.
Residential.

ii.
A current aerial photograph (a minimum resolution of six-inch pixels) with an overlay of the development, an outline of the tree area(s) and the tree area(s) and understory that are to be preserved to meet the requirement standards;
