2.2 DETAILED SCOPE OF WORK The anticipated scope of work includes, generally: Attached is Roseville’s public tree inventory (ATTACHMENT L). Roseville currently has 1702 public as trees. The contractor is responsible to field verify the City’s tree inventory. This inventory includes all public land including city parks, boulevards, public buildings (Roseville City Hall, Roseville Skating Center) and the Cedarholm Golf Course and Community Building. Vendor shall propose a multi-year plan for the removal and replacement of all Public Ash Trees in Roseville in accordance with the parameters below. Treat, plant and remove in accordance with the agreed upon plan. Plant trees in accordance with Roseville’s acceptable species list (ATTACHMENT M). Mitigate public safety issues and hazard trees in a timely manner during the duration of the plan. In addition, the proposer shall accomplish the following objectives as a part of the work of this proposal package: Propose an EAB mitigation plan for Roseville’s public ash trees. T he program may include a combination of phased planning, removal, preemptive replacement (buddy trees), treatment and replacement. The EAB mitigation plan objectives shall be: a. The eventual removal of all of Roseville’s public ash trees. By the programs completion, all of Roseville’s public ash trees shall be removed. The city desires that this be accomplished in a multi-year, planned manner. b. Replace all of City’s public ash trees. At the termination of the program, that city shall have each removed ash tree replaced by another, species diverse tree. To minimize the immediate impact of removal, proposers shall consider pre-planting “buddy trees” in advance of planned removals. c. Minimize the immediate impact on the City’s tree canopy. It is understood that removal of this scale will cause both short term and long term changes to the tree canopy. However, the city envisions a phased approach that combines treatment, buddy trees and other strategies to prevent overwhelming changes to neighborhoods tree canopy. d. Ensure the long-term species diversity of the Roseville’s urban forest. The proposer shall propose which species will be used for replacement trees and how their location and placement shall be selected. The City aims to diversify its species to prevent substantial losses in the event of future disease events. e. Ensure Community Safety The vendor’s proposal shall ensure that the program is safe and does not result in danger or hazard trees due to EAB degradation. This shall include both a preventative approach and a responsive approach to significantly sick trees. Page 2of 5
