Attachment A City of Roseville 11-16-15 Page 3 Per the proposed language, the following trees would be exempt from the inventory: a. Invasive Species that must be removed anyway; A tree suffering from a major insect infestation or pathological problem that cannot be resolved; c. A tree experiencing extensive decay or hollow; A tree that has suffered damage or is in poor condition such that its life expectancy is less than ten (10) years. (F) Incentive Multipliers —"Incentive Multipliers" are essentially replacement rates for each classification type, but we are also using them to provide bonuses when trees are preserved over and above what is required. We demonstrate how they function within subsection (G). (G) Tree Preservation Plan Set Required — This section details what plans sets must be provided with the triggering application. Things to note about this section include: a. We are suggesting the City no longer allow a surveyor to prepare the plans as such inventories often times include misidentified trees, and expertise is needed to identify "exempt" trees. b. Two years would be the validity period for a tree inventory. c. The four components of the required plan will bring clarity to the tree preservation process. At its core, this process will identify what exists before activities occur, what areas will be impacted by the proposed activity, and what the site will look like following activity. A required matrix (example below) will provide staff with an easy-to-reference summary of what is required on any given site.
