From an April 28 City of Piedmont press release:
Three new trees in Piedmont’s parks and public spaces have joined the ranks of “Piedmont Heritage Trees.”
The newly designated Heritage Trees were selected by the Park Commission from a pool of community nominations and announced at the city’s annual Arbor and Earth Day Celebration on Thursday, April 23 at Community Hall.
The city’s Heritage Tree program aims to raise awareness of and appreciation for Piedmont’s diverse urban forest.
Trees selected for recognition this year were:
• Coast Live Oak in Upper Dracena Park, nominated by Jack and Sharona Fischrup
• Gingko street trees on King, nominated by Cindy Rafton
• Redwood in lower Dracena Park, nominated by Richard Przybyla

Five community members or groups submitted nominations for this year’s Heritage Tree program. The City extends sincere thanks to everyone who participated.
Each year, the Park Commission names up to five trees “Piedmont Heritage Trees.” Nominators of selected trees are recognized at the Arbor & Earth Day celebration and receive a Piedmont Heritage Tree lapel pin. Nominators will also be named on future signage marking heritage trees.
