(Amended by Ordinance Nos. 188278 and 188816, effective March 16, 2018.) A tree plan submittal shall include the following information. The tree plan information may be combined with other relevant plan sheets. The submittal shall include:
A. Site Plan Requirements. The site plan shall include the following information with sufficient detail to show that the proposal complies with this Title.
1. Existing improvements;
2. Any construction staging areas on site;
3. Proposed alterations including structures, impervious area, grading, and utilities;
4. Existing trees:
a. Trees on the site. Indicate the location and the diameter size of:
(1) Any Heritage Trees and trees required to be preserved as part of a condition of land use approval. These shall be clearly labeled.
(2) All Private Trees at least 12 inches in diameter and all City Trees at least 6 inches in diameter located completely or partially on the site. On City-owned or -managed sites, the City Forester may require smaller size trees be shown.
(3) Trees smaller than 6 inches in diameter shall be shown when proposed to be retained for tree density credit.
Applicants using the development impact area option as described in Section 11.50.030, need only identify the trees on the site inside and 25 feet beyond the edge of the development impact area. For all trees shown to be retained on the tree plan (including those beyond the development impact area), tree protection methods detailed in Subsection 11.60.030 C. shall be implemented. Protection may be achieved using the Prescriptive Path or Performance Path.
b. Trees in the street. For the street area adjacent to the development site or development impact area, indicate the location and the diameter size of:
(1) Any Heritage Trees and trees required to be preserved as part of a condition of land use approval
(2) All trees within the adjacent street that are at least 3 inches in diameter.
Applicants using the development impact area option within the street when not associated with development of an adjacent site as described in Section 11.50.030, shall identify trees 3 or more inches in diameter inside and 15 feet beyond the edge of the development impact area.
When the 15 foot distance extends onto property outside the street, provide estimates of tree size and location for trees 6 or more inches in diameter on these properties. For City projects, the City Forester or project arborist may determine which trees on adjacent properties shall be identified per this Subsection.
5. Proposed tree activity:
a. Indicate trees to be retained and proposed tree protection measures meeting the specifications in Chapter 11.60. Trees that are retained but are not protected in accordance with the protection requirements in Chapter 11.60 may not be used to meet preservation or density standards.
b. Indicate trees to be removed. It is the applicant’s responsibility to obtain the appropriate consent from the adjacent property owner for tree removal when the tree is only partially on the site.
c. Show location, species, planting size and number of trees proposed to be planted. Trees to be planted shall meet the specifications in Chapter 11.60.
B. Narrative requirements.
1. If alternative tree protection measures are proposed, documentation addressing the requirements in Section 11.60.030, Tree Protection Specifications, shall be included.
2. If a tree is to be exempted from tree preservation standards based on poor tree health or condition, supporting documentation from an arborist shall be included.
3. If a tree is to be exempted from tree preservation standards based on it being listed on the Nuisance Plants List, supporting documentation from a landscape professional or an arborist shall be included.
