Seattle has posted an online map of our “urban forest,” including specially recognized “heritage trees.”
Maple Leaf has three of them, including this Akebono Cherry, which the city says has a diameter of 32 inches. 
Heritage trees, first recognized here in 1996, must meet these criteria:
Specimen: A tree of exceptional size, form, or rarity.
Historic: A tree recognized by virtue of its age, its association with or contribution to a historic structure or district, or its association with a noted person or historic event.
Landmark: Trees that are landmarks of a community.
Collection: Trees in a notable grove, avenue, or other planting.
Interestingly, the grove of trees at the old Waldo Hospital along 15th Avenue Northeast is not included in the program. The Maple Leaf Community Council and the Menachem Mendel Seattle Cheder Day School, which currently occupies the property, won an Audubon award for preserving those trees.

My family LOVES this tree. We call it the wishing tree and we often stop to make wishes under it while out for walks. It glows at night when it is full of blossoms.
My favorite tree in the neighborhood!
