In September 2015, the City and County of San Francisco awarded ArborPro, Inc. a $350,000 contract to complete a city-wide tree inventory. The initial funds available allowed us to inventory of over 80,000 tree sites. Once our team completed the initial project on schedule, the city amended the agreement to inventory up to 140,000 tree sites. ArborPro utilized a five-man team lead by Tree Inventory Project Manager Ken Greby. As with all tree inventory projects, our team performed the survey on a neighborhood-by-neighborhood basis. After completing each neighborhood, we provided the City of San Francisco with a summary neighborhood report that included i-Tree analysis. ArborPro also provided weekly updates as we progressed through the City. Because this tree survey had been a highly political and community-sensitive project, the City created a website to share these updates with the community.
