San José Street Tree Project

This page explains why I may be visiting or observing street trees in your neighborhood. It is intended as a brief public information page for residents, not a full research report.

Please note: This page shares general project information only. It does not report homeowner-specific findings, exact tree locations, or property-level conclusions.

What this project is about

This project is examining what happens at previously documented street tree planting sites over time, especially where trees were recorded as being in poor condition or dead in a 2020 baseline inventory. The focus is on broad patterns of tree persistence, replacement, and site conversion.

In plain terms, I am trying to understand whether former tree sites remain tree sites, become planted with something else, or are converted to non-planting surfaces. The project also considers how these choices relate to long-term canopy potential and the City of San José’s urban forest goals.

What I may be doing in the field

  • Looking at the current condition of a street tree planting site from the public right-of-way
  • Checking whether the original tree is still present
  • Noting whether the site now contains a new tree, another plant type, bare planting area, hardscape, or a stump
  • Recording observations in a mobile GIS field form

What I am not doing

  • I am not evaluating private yards beyond what can be observed from public space
  • I am not issuing citations or acting in an enforcement role
  • I am not publishing household-specific findings on this page

Frequently asked questions

Why are you looking at street trees in front of homes?

The project is focused on street tree planting sites and long-term patterns in urban forest change. Observations are made from public space and are limited to broad site conditions relevant to the study.

Are you with the City?

No. I'm an independent researcher who is not affiliated with the city or any business interest. My goal is to share new information about the San Jose urban forest with arborists, policymakers, and the general public.

Will exact results for my property be shared here?

No. This page is intended for general project explanation and neighborhood-level fieldwork status only.
