TREE COMMITTEE AGENDA REPORT
SUBJECT: SECOND REVIEW OF THE PROPOSED MASTER STREET TREE LIST
FOR THE 2022 CITY ENGINEERING STANDARDS UPDATE
FROM: Anthony Whipple, City Arborist
Phone Number: (805) 781-7021
Email: awhipple@slocity.org
1.0 RECOMMENDATION
Review and discuss the proposed Master Street Tree List and provide feedback to staff
for the 2022 City Engineering Standards Update.
2.0 COMMITTEE PURVIEW
The Tree Committee’s role is to review the proposed Master Street Tree List and give
feedback to staff for future modifications to the Street Tree List within the City’s
Engineering Standards.
3.0 PROJECT DESCRIPTION
The City updates its Engineering Standards every two years for use on development and
improvement projects within the City limits. The City Standards includes a Street Tree List
that is used for selection of required plantings.
As part of this process, the City Public Works Department updates the Standards when
changes are found to be beneficial to the improvement. As temperatures and drought
conditions increase within the City, there is a desire to ensure new tree plantings are
successful. To do so, the Master Street Tree list will need to be altered.
After review of the proposed list, staff would like feedback on proposed alterations to be
explored.
