If you own property in Columbia County or are considering purchasing or developing property, contact us first and we will assist you in navigating the land use process by providing information related to zoning, permitting, dividing land, general land development, structure placement, and if your property contains environmental constraints such as floodplain, wetlands or other sensitive habitat areas.
