Our California Davey Resource Group, Inc. (DRG) office works with municipalities, businesses, and a variety of organizations to manage and protect the vital ecosystems known as urban forests that help filter water and air, control stormwater, conserve energy, and provide animal habitats.
Our team specializes in the nuanced needs of the Bay Area and Northern California surrounding areas. The staff of certified experts is ready to help you reach your goals.
In addition to regular Tree Assessments, Inventories, and Risk Assessments, we also offer a variety of Consulting Services, including:
Tree risk assessment reports, tree protection zone calculations, mapping of critical root zones and trees to correspond with project plans, soil analyses, on-site monitoring, and tree preservation action plans.
Our team of experts can examine and document tree health, assess the value of individual trees or overall benefits provided by trees in a neighborhood, city, or state, and spot potential safety risks.
Customized and turnkey solutions for master plans, tree inventories, data collection and analyses, invasive species mitigation, species selection, planting programs, and maintenance schedules.
With high-resolution GIS data, we can effectively classify and assess a community’s tree canopy for growth modeling, priority tree planting and planning, and the management of energy conservation, stormwater, and water resource initiatives.
With local offices across the country, our team of experts can provide the guidance, analysis, and quality service you need to manage the natural resources on your property. From wetlands and streams to stormwater management and tree inventories, we offer turn-key solutions for clients nationwide.
Whether you’re looking to plant new trees as part of a construction project, you have trees on your property that have grown to a size that threatens the safety of your property, or you need to preserve a damaged or decaying tree, we can help you maximize your green investment.
Davey offers tree inventory software, AI data collection, drone imaging, and image CAD drawing services, so you can plan the locations of the trees on a new construction project, as well as management planning and permitting assistance, for an end-to-end solution that gives you the expertise and support you need.
We also provide Level 1, 2, and 3 tree assessments that leverage sonic tomography and ground-penetrating radar to help you determine the level of risk your trees pose to the health and safety of your property, so you can make the right decision when it comes to planning and executing tree work.
Trees are a vital part of any landscape, and in an urban setting, they’re even more important to the overall health of the environment. Davey’s Urban Forestry services can help you plan, monitor, and maintain the trees throughout your property or municipality.
From field inventories to pest management and contract arborist services, our trained experts can keep your trees healthy and looking their best. Additionally, our proprietary TreeKeeper software platform allows you to manage your tree inventory data quickly and easily, so you always know which trees need attention.
Davey’s trained experts can help your urban forestry initiatives from the planning stages to the planting phase, to ongoing maintenance and expansion. Our services include:
