Tigard-Tualatin School District for Alberta Rider Arbor Day tree planting Y +1 Memorandum of Understanding Between the Tigard-Tualatin School District and the City of Tigard Introduction In celebration of Arbor Day 2009,the City and the Tigard-Tualatin School District(TTSD)will be planting over 100 trees at the Alberta Rider Elementary School campus.This expanded planting effort has been made possible through close collaboration with Darin Barnard,the Principal of Alberta Rider, parent volunteers,TTSD staff,and City of Tigard staff and local contractors.The planting palette includes mostly native trees chosen for their low water and maintenance requirements.The trees will be provided with automatic drip irrigation until the roots become established. Due to funding shortages,the landscape budget was cut during the development of the Alberta Rider campus.This tree planting partnership will provide beauty,wildlife habitat, stormwater management, and shelter from the sun and wind for students and neighbors of Alberta Rider Elementary. P se The City of Tigard (City) and the Tigard-Tualatin School District (District) recognize that there are areas of mutual interest,which,when pursued cooperatively support each entity's ability to plant and maintain trees on District property in the City of Tigard. This Memorandum of Understanding defines the roles of the City and District with respect to furthering their cooperative efforts to enhance the City of Tigard with additional trees.The City recognized the value of planting and establishing trees on District property to increase the size and quality of the City's tree canopy,the District recognizes the need to provide maintainenance to the trees after planting so that the health, safety,and longevity of the trees is maximized.Thus,on this 3rd day of March,2009 these parties enter into this Memorandum of Understanding,the intent of which is to further City and District cooperation. Toward this goal the District will: •Periodically monitor the health of the newly planted trees on Attachement 1 during the first three years after planting. • Contact the City if any of the newly planted trees on Attachment 1 begin to die during the first three years after planting. •Periodically monitor the functioning of the newly installed irrigation system on Attachment 2 during the first three years after planting. • Contact the City if the newly installed irrigation system on Attachment 2 should become damaged or destroyed, or otherwise fail to function properly. •Provide and purchase irrigation water when needed for the newly planted trees on Attachment 1 during the first three years after planting. Irrigation will be controlled by the District through a handheld unit provided by the City. The City will provide training on the use of the irrigation system if requested by the District. •Provide and purchase irrigation water throughout the summer for the newly planted trees on Attachment 1 during the first three years after planting. Irrigation will be controlled by the District through a handheld unit provided by the City. The City will provide training on the use of the irrigation system if requested by the District. •Allow the City to secure the valve boxes housing the newly installed battery operated irrigation controllers on the Attachment 2 for three years after installation. •Allow the City to retrieve the battery operated irrigation controllers of the newly installed irrigation system on Attachment 2 three years after installation. • Replace any trees that die within the first three years after planting if the cause of death is determined by the City to be from lack of maintenance or intentional removal. Lack of maintenance will be considered to be: o Failure to notify the City if any of the newly planted trees on Attachment 1 begin to die during the first three years after planting. o Failure to notify the City if the newly installed irrigation system on Attachment 2 should become damaged or destroyed, or otherwise fail to function properly. o Failure to provide irrigation water when needed for the newly planted trees on Attachment 1 during the first three years after planting. o Failure to provide and purchase irrigation water throughout the summer for the newly planted trees on Attachment 1 during the first three years after planting. •Maintain trees after planting so that the health, safety, and longevity of the trees is maximized. Maintenance of the trees shall conform to tree care industry standards, occur for the life of the trees, and include but not be limited to: o Pruning as needed;please provide additional information on what this means o Water management; o Protection during future construction activities within their critical root zones o Pest Control as needed;this one also as well as the next two items o Fertilization as needed;and o Removal should the tree(s) become a hazard to people or structures, and pruning is unable to abate the hazard. •Replace any trees with the same species and size on Attachment 1 that die due to lack of maintenance, negligence,or intentional removal. • Exclude and protect students,parents,personnel, and campus visitors from construction areas until planting and irrigation installation is complete. • Hold harmless,indemnify and defend the City,its officers,agents, and employees from all claims for damages or injuries which may occur as a result of the trees and irrigation system, and/or the planting of the trees and irrigation installation on the attached plans.
