Walking the walk

Trees need space—above and below ground—to thrive. Unfortunately, sometimes a tree's roots and branches seem in direct competition with a city's infrastructure. Sidewalks, for example, need to be built and maintained, but doing so could damage or kill trees if not done carefully.

In Maintaining Sidewalks Without Uprooting Trees (Monday, Sept. 11, 11 to 11:50 a.m.), Los Angeles chief forester George Gonzalez will talk about the high priority his city has placed on retaining mature trees while keeping the sidewalks in tiptop shape. Since 1999, Los Angeles has repaired approximately 300 sidewalk miles, which could have impacted as many as 15,000 trees. Thanks to innovative root-pruning techniques and alternative sidewalk construction concepts (such as meandering, ramping, and use of flexible paving materials), only 7% of the trees have needed replacement.
