A key step in assessing individual and contextual tree needs involves field review of the trunk flare and surficial roots, width of pedestrian passing area, grade, pavement conditions within surrounding hardscapes, adjacent curb lane use, and nearby utilities and structures. Each of these elements impacts potential modifications to improve the space available (surface area and soil volume), adjacent grades, and surface treatments for existing trees.

The article "Tree Pits Are the Pits, But We Can Make Them Better" from DeepRoot discusses the challenges and potential improvements for tree pits, which are small, often inadequate spaces for urban trees. These pits typically have compacted soil, limited rooting space, and poor drainage, which hinder tree growth and health. The article highlights the importance of creating better environments for urban trees to thrive, emphasizing the need for improved soil conditions, adequate rooting volume, and proper maintenance.

Key solutions proposed include using structural soil to support both the tree and pavement, installing tree grates or permeable pavers to allow for better water and air exchange, and incorporating sustainable urban drainage systems (SUDS) to manage water runoff. The article also stresses the importance of community involvement and education in maintaining healthy urban trees.
