Atherton Tree Service

Atherton is known for its beautiful tree-lined streets, expansive estate properties, and mature urban forest that help define the community’s natural beauty and character. Trees throughout Atherton provide far more than visual appeal — they create shade, improve air quality, reduce noise, support local wildlife, increase property value, and contribute to the peaceful and environmentally rich atmosphere that makes Atherton one of the most desirable communities on the Peninsula.
The area is home to a variety of important native and ornamental tree species, including Coast Live Oaks, Valley Oaks, California Bay Laurels, and the iconic Coast Redwoods that thrive throughout the Bay Area. Coast Live Oaks are especially valuable throughout Atherton because of their longevity, broad canopies, and environmental benefits, while Coast Redwoods are admired for their incredible size, beauty, and ability to help improve air quality and support local ecosystems. Mature trees throughout Atherton also play an important role in reducing heat, conserving energy, and preserving the natural privacy and character of residential properties.
Proper tree care and maintenance are essential to protecting the health, structure, safety, and longevity of Atherton’s trees. Without routine pruning, monitoring, and preventative maintenance, trees can become structurally weak, diseased, overgrown, or hazardous during storms and high winds. Responsible tree care helps preserve the long-term beauty and environmental value of the community while reducing potential risks to homes, pedestrians, vehicles, and surrounding property.
At JJI Tree Service, we are committed to helping protect and preserve Atherton’s trees through safe, professional, and environmentally responsible tree care services. Our experienced arborists and tree care specialists provide expert tree trimming, pruning, tree removal, emergency tree services, stump grinding, and preventative maintenance designed to support healthy tree growth and maintain the natural beauty of Atherton for future generations. We proudly follow ANSI arboricultural standards, proper pruning techniques, and local tree ordinances to ensure every project is completed safely, responsibly, and professionally.

Atherton has some of the strictest tree protection ordinances on the Peninsula, designed to preserve the community’s mature trees, estate landscapes, and urban forest canopy. The Town of Atherton carefully regulates tree removal, major pruning, and construction activities that may impact protected or heritage trees. These ordinances help maintain the natural beauty, environmental benefits, and property value that trees provide throughout the community. Proper tree care and ordinance compliance are extremely important because unauthorized tree removal or excessive pruning can result in violations, penalties, replacement requirements, and long-term damage to valuable trees.
Under Atherton’s tree ordinance, many trees may qualify as “heritage trees” depending on the species, size, age, and location of the tree. Protected native oak species such as Coast Live Oaks (Quercus agrifolia), Valley Oaks (Quercus lobata), and Blue Oaks (Quercus douglasii) receive special protection throughout Atherton. In many situations, oak trees measuring 48 inches in circumference (approximately 15.2 inches diameter measured 54 inches above natural grade) may require permits before removal or significant pruning work can take place. Trees located outside the primary buildable area of a property may also qualify as protected heritage trees if they meet specific size requirements.
Atherton also strictly regulates excessive pruning and improper trimming practices. Harmful pruning methods such as topping, lion’s tailing, excessive canopy reduction, and improper branch removal are prohibited because they can create hazardous conditions, weaken tree structure, increase disease risk, and permanently damage the long-term health of the tree. Atherton requires ANSI A300 pruning standards to be followed for protected trees and places significant emphasis on preserving tree health and structural integrity.
Certain tree species are exempt from heritage protection requirements regardless of size, including some Acacia species, Tree of Heaven, Mimosa, and Eucalyptus species. However, determining whether a tree is protected can often be complex because regulations depend on factors such as tree species, location, trunk size, age, buildable area restrictions, and overall tree condition.
At JJI Tree Service, we are experienced in working with Atherton tree ordinances, permit requirements, protected tree regulations, and proper pruning standards. Our knowledgeable arborists and tree care specialists can help homeowners, estate managers, and contractors understand local tree regulations and assist throughout the permit application and approval process when required. We help ensure all tree trimming, pruning, and removal projects are performed safely, professionally, and in full compliance with Atherton’s municipal code and arboricultural standards.
