US Environmental Protection Agency Street Tree Report

“This guide is intended to help engineers, planners, developers, architects, arborists, and public officials understand how trees perform and interact in a stormwater management system, and the new technologies that are being used to increase the stormwater utility function of the urban forest, even in the densest urban environments.”

2011 Public Tree Inventory Report

In 2011, a team from Pennsylvania State University conducted a study of trees in Lancaster’s public parks and on public rights of way. Their work resulted in a database that the City is in the process of adapting for day-to-day maintenance and environmental services purposes. Using this data, the City will be able to calculate the economic and environmental benefits of street trees throughout Lancaster.

2011 Tree Canopy Report

The University of Vermont’s Spatial Analysis Laboratory played a crucial role in quantifying exactly how much shade trees mean to the city. Using aerial data and Geographic Information systems, the team was able to identify both the benefits and shortcomings of the City’s existing tree canopy. Beyond providing beautiful shade and foliage, street trees can increase property values, and cooling costs, naturally filter air, process stormwater runoff and mitigate greenhouse gas emissions.

Tree Progress Report 2014-15

In 2016 a comprehensive review of the tree program was conducted, including funding, planting, removal, distribution, and more. This also provided an opportunity to update the City tree inventory.

Protecting Trees in Development Projects

Preserving trees in developments increases a project’s attractiveness, monetary value, and marketability by providing aesthetic and functional values. Lots where trees are preserved can be sold more quickly and at higher prices. Research has shown that mature trees increase the worth of a property up to 12 percent. Developers who understand these values realize that it is in their best interest to encourage the preservation of trees and green spaces. Developers can take advantage of different opportunities when considering the preservation of trees. Individual historic, landmark, and ornamental trees are all good choices for preservation, as are native trees in groves and woodlots.
