Tree Mitigation
Key Points
• All onsite trees (forty-four total) are proposed to be removed. • Forty-seven replacement trees are proposed.
• Due to landscape area space restraints, replacement trees will not include tree species removed. • Mitigation includes a penalty for unpermitted removal of trees #001 and #006 (22” valley oak and 20” valley oak) at four #15 size trees per six-inch dbh.
• Due to construction impacts, three off-site trees are proposed for removal (#041, #042, and #043). • Tree mitigation calculations are based on two - #15 size trees per six-inch dbh of all trees to be removed.
• Per the Planning Department recommendation, the following tree quantities are used to determine mitigation values using up-sized trees.
• Three 15-gallon trees per one 24" box tree.
• Five 15-gallon trees per one 36" box tree.
• Eight 15-gallon trees per one 48" box tree.
