Ecosystem Benefits <br />The urban forest holds millions of dol lars of savings i n <br />avoided infrastructure costs, pol lution reduction, and <br />stored ca r bon. Using the best available science from <br />USDA Forest Service's i-Tree Landscape tool, pai red <br />with the f indings from the UTC assessment, <br />ecosystem benefit values were calculated for the ai r <br />quality, stormwater, and carbon functions provided <br />by the urban tree canopy in San Leandro. The i-Tree <br />tool reported monetary, pollution removal, and <br />benefit value c oeffic ients per tree canopy acre, <br />tailored to the San Leandro area. The per acre <br />coefficients were then applied to the 207 8 UTC data <br />(686 acres). <br />A i r quality in San Leandro is estimated to be <br />i mproved by removing over 37 tons of pollutants out <br />of the air annually, which otherwise may ca u se <br />expensive or life-threatening respiratory issues. Every <br />year, trees in San Leandro d ivert over 27 million <br />gallons of stormwater away from sewers and <br />roadways. Citywide, San Leandra's trees have stored <br />approximately 5,400 tons of carbon, valued at over <br />$928,000, and each year the tree canopy abso r bs and <br />sequesters approximat ely250 tons of ca r bon dioxide, <br />valued at over $42,000. T hese an n ual benefits <br />re present over $844,000 and a value of $9.73 per <br />capita. <br />Annual Citywide Benefits Provided by Trees 1n San Leandro <br />27 <br />Air Quality Stormwater Carbon Total Annual Carbon Storage <br />Runoff Avoided Sequestration Value (lifetime) <br />$612,170.93 $189,467.61 $42,556.24 $844,794.78 $928,525 .0 5 <br />31.47 tons 21.27 million 24 9.51 tons 5,444.21 tons g a llons <br />Additional i-Tree m e thodology and docum entation can b e fo un d h e re: <br />https:llwvvwitreetoo/s.o rq/supportlresources-overviewli-tree-m e thods-and-files
