We support preserving Arlington’s urban forest and are concerned about the rapid loss of trees on public and private lands. The loss of 81 trees or more along only 1400 feet of Donaldson Run’s Nature Area is very serious and deserves careful reconsideration. These irreplaceable mature trees are important to the environmental quality, energy efficiency, and psychological health of Arlington. The Donaldson Run Tributary B steam restoration project, costing taxpayers over $1 million, sacrifices the broader natural environment for a single storm water purpose. This must be put on hold until better alternatives are developed to use the money more effectively to meet all the community’s goals.
