Tree Assessments & Tree Protection Plans
Regulatory Compliance for Local Tree Ordinances
Communities commonly adopt tree ordinances to ensure trees are retained during development projects. Such ordinances often require a tree assessment or tree survey that includes an evaluation of the tree’s location, species, diameter, and condition. Many of these tree ordinances also often require project plans to include provisions for tree replacement or tree protection.
DRG’s experienced team of certified arborists can help you interpret local ordinances, develop the right tree assessment approach, and prepare tree protection plans to meet local regulatory requirements.

Wetland Permitting & Delineation
Applying for necessary water resource permits can be a lengthy and confusing process. Having accurate information is a critical first step toward obtaining your permits in a timely fashion, and can help avoid expensive project delays.
We have extensive experience with stream and wetland delineation and permitting projects ranging from single-family property owners and large residential subdivisions to oil and gas pipeline construction and development of hospitals and other commercial properties across the country.
