Using Permeable Pavement for Sidewalks Saves Trees: Does Public Opinion Matter?

Mature trees have large root systems that break and lift sidewalks, causing hazards for pedestrians & costing cities. Removing a tree and replacing the adjacent sidewalk costs $1K to $3K. Retaining tree canopies and maintaining walkable, safe sidewalks requires creativity. The objectives of this study were to:

    1. Reduce urban tree loss from sidewalk damage.
    2. Test two alternative sidewalk materials.
    3. Gauge and increase public support for alternative sidewalk materials.
