Stefan Bolliger Associates Inc. has an ISA Certified Arborist on staff to perform tree and vegetation inventories and evaluations. These services include, but are not limited to, tree and vegetation inventories, tree preservation plans and reports, vegetation evaluations and tree compensation calculations. Our team works with the regulating authorities on a case-by case basis to determine what vegetation inventories and evaluations are necessary for every project. Our office strives to keep up with the technological advances. With that being said we are now actively using AutoCAD Mobile which allows us to use GPS location to more accurately prepare vegetation inventories. Throughout this process we maintain an open and honest dialogue with our clients so that we may satisfy all jurisdictional requirements while still achieving the design intent.
