Alameda County Tree Removal Permit Information

Alameda County

Arbortech Tree Care & Landscaping has been providing affordable, trustworthy tree services in Hayward and surrounding cities in Alameda County. For 30+ years we’ve worked hand in hand with Alameda County residents, municipal governments, property management groups, and other commercial businesses providing expert tree care service.

Alameda County is the 7th most populous county in the State of California and 21st most populous nationally. Alameda County’s history with trees goes back to its inception. Alameda in Spanish means either “a grave of poplars… or a tree-lined street.” The willow and sycamore trees along the banks of the river reminded the early Spanish explorers of a road lined with trees. Here at Arbortech, we aim to preserve the beauty and diversity of urban trees in Alameda County. Fortunately, Alameda County has a wide variety of trees including eucalyptus, maples, oaks, pines, and redwoods. Arbortech has the professional equipment and expertise to assist you with any tree care service. Arbortech provides excellent tree care services everywhere from Livermore, Pleasanton to as far as Berkeley, Oakland and every city in between (Fremont, Hayward, Union City, and others.) Whether you are looking to get tree removal, tree pruning, or a tree inspection from a certified Arborist, feel free to call (510) 881-8733 to book a FREE estimate appointment.
