An assessment of the vegetation structure, function, and value of the City <br />of Pleasanton urban forest was conducted during 2024. Data from 23301 trees located throughout City of Pleasanton <br />were analyzed using the i-Tree Eco model developed by the U.S. Forest Service, Northern Research Station. <br />•Number of trees: 23,301 <br />•Tree Cover: 225.3 acres <br />•Most common species of trees: Sycamore spp, Coastal live oak, Coast redwood <br />•Percentage of trees less than 6" (15.2 cm) diameter: 28.0% <br />•Pollution Removal: 5.337 tons/year ($21.2 thousand/year) <br />•Carbon Storage: 10.92 thousand tons ($1.86 million) <br />•Carbon Sequestration: 333.2 tons ($56.8 thousand/year) <br />•Oxygen Production: 888.4 tons/year <br />•Avoided Runoff: 1.426 million gallon/year ($12.7 thousand/year) <br />•Building energy savings: N/A – data not collected <br />•Avoided carbon emissions: N/A – data not collected <br />•Replacement values: $99.4 million <br />Ton: short ton (U.S.) (2,000 lbs) <br />Monetary values $ are reported in US Dollars throughout the report except where noted. <br />Ecosystem service estimates are reported for trees. <br />With Complete Inventory Projects, oxygen production is estimated from gross carbon sequestration and does not account for decomposition. Oxygen <br />production in Plot Inventory Projects is estimated from net carbon sequestration. <br />For an overview of i-Tree Eco methodology, see Appendix I. Data collection quality is determined by the local data <br />collectors, over which i-Tree has no control.
