UPDATE as of May 16, 2011
The City of Walnut Tree Maintenance Program is currently about 75% complete with no major impact to residents. Crews will now be working on Shadow Oak Drive, Creekside Drive and Grand Avenue.

In an effort to increase public safety along our roads and sidewalks, the City of Walnut has undertaken an audit of its tree inventory and determined to be necessary to remove certain trees and provide extensive trimming of others.

The City of Walnut, at the recommendation of a certified arborist, will remove 530 trees and replace those trees removed with 100 new trees.

The City has over 15,000 trees in its inventory, compromised of a wide assortment of species. Over 80% of the inventory planted was during the mid 1980s, when the City was in its development peak, and some trees were planted too close together causing overcrowded areas.

Funding to undertake this effort will be provided by savings from Capital Improvement Projects, therefore there is no impact to the City’s general fund.
