Please note that we work WITH the City of Oakland but are not a part of the official City of Oakland's Tree Services. 

The City of Oakland has a list of approved “Street Trees” that you can choose from. 

Download the current (2017-'18) City of Oakland – Master Street Tree List (PDF) here.
Effective April 2017 until a new tree list is released.  
Some new species have been added since the 2016-'17 list, and the required well-sizes for some species have been changed (Medium to Small, or Large to Medium, or vice versa).  The new list also includes the relative height (stature) and rate of growth of each species.

In the columns below, you can click on the botanical names and/or variety names to be linked to more information.
Most of the links go to the Tree Selection profile at CalPoly's SelecTree website.
*External links are not intended to be endorsements of any product, service, or advertisement and we cannot guarantee the accuracy of content found at any website link. 
​
If you don't know where to start and you want a shorter list to consider, we have indicated some of our favorites at the top of the columns.

The list of approved street-trees also includes a category for Small Wells (well min. 2'x3') ...
... but Trees for Oakland does not plant them.
They are suitable for narrow or confined spaces, but they will never grow large enough to sequester enough carbon and give a good return on our funders' investment.
If we cannot find a way to make your planting area at least 3' wide, you may buy one of these "Small well" trees and plant it on your own, or we can forward your request to another organization to provide one for you.

There is one more entry on Oakland's list that is a special case:
Magnolia grandiflora 'St. Mary' or 'Little Gem'
Southern Magnolia (smaller varieties)

• Evergreen
• Small stature (20'-25' x 10'-15')
• Flowers: Showy White, Fragrant
• Less drought-tolerant than other species on this list
• These varieties have relatively aggressive roots for their small size, so Oakland requires a "Medium" space for them to be official (min. 3'x6' or 4'x4'), but they are too small to qualify for our grant.

The City of Oakland's size categories for trees depend on the size of the available tree well.
Note that the required size of the well does not necessarily correspond to the size of the tree.  The revised species list in April 2017 includes a separate category for the height or stature of each species.

• Small: Minimum 2'x3', or a continuous strip 2' wide, and all locations with overhead high-voltage wires.  (On a case-by-case basis, the City will accept as "official" some taller species under high-voltage wires that are more than 35' up.)
  
• Medium: Minimum 3'x6' or 4’x4', or a continuous strip 3' wide.  Since CAL-FIRE requires at least 24 square feet per tree (3'x8', 3.5'x7', or 4'x6'), a grant-eligible well of "Medium" width must be longer than what the City would allow.
  
• Large: Minimum 4'x6' or 5'x5', or a continuous strip 4' wide.  This size automatically meets the CAL-FIRE requirement of 24 sq.ft. per tree.
  
• Extra-Large: Minimum 6'x8', or a continuous strip 6' wide.  This size automatically meets the CAL-FIRE requirement of 24 sq.ft. per tree.
