2017 Tree Assessment

California has had several years of severe weather – extreme drought, followed by one of the wettest winters on record. This has unfortunately stressed and damaged trees.

In the interest of public safety, the Town of Hillsborough hired a consulting arborist, Kevin Kielty, to conduct an assessment of trees and shrubs adjacent to Town roadways. The purpose of the inspection was to identify trees near the public roadway that are in a declining condition or in need of maintenance.

Residents with trees in need maintenance and near a public roadway received a letter from the Town describing the tree and type of maintenance needed. The letter also outlined resources available to residents receiving a letter, including:

• A temporary reduction in drought tree removal permit fees (Resolution and Staff Report);
• A list of tree service companies who have business licenses to do work in the Town of Hillsborough can be found here;
• Information about when and how to schedule an underground utility service (USA) marking ( and PG&E’s safety digging website (;
• Information regarding tree maintenance in right-of-way and Municipal Code 8.16.030;
• A suggested list of street trees for planting near public roadways (HBF Tree List);

If you received a letter and have any questions about how to proceed, please contact John Iaquinto at 650-375-7444 or
