The Clean Water Project is a major water quality initiative of the Hartford Metropolitan District Commission. One of the five strategies to achieve project goals is sewer separation. Torwood Street in Hartford has the oldest and most mature street tree canopy inventory in the city. When project plans were announced, residents decried plans as they called for removal of most of these trees to perform the sewer separation.
Using ArcGIS online on mobile devices, we were able to inventory the trees and create a tree management plan on site, export the data to a web app for client review, and export the data to the client for inclusion into engineering plans for decision support related to tree condition and project impacts to trees.
An alternate design that retains most trees and accomplishes project objectives was developed with community input based on the resulting data and revised plans.
