Environmental Protection Area signage is used along the boundary of sensitive environmental features within residential subdivisions to alert residents to their presence and the need for good environmental stewardship in these areas. The signage protects environmentally sensitive features from secondary impacts after completion of construction activities. Waters of the U.S. and state surface waters, including wetlands, Resource Protection Areas (RPA), and Stream Protection Areas (SPA) should be maintained only as natural areas, with minimal alterations, so that they may function properly within the watershed.
Design Criteria
Location and Spacing: Generally, the signs will be located on the lot lines at the intersection of the landward edge of the wetlands, RPA buffer, or 50-foot SPA buffer, and at other locations, which will approximately delineate the wetland/RPA boundary/SPA boundary. Additional signs will be located as necessary such that the spacing between two consecutive signs does not exceed 100 feet. Signs will be equally spaced on the lot lines.
Installation: Where possible, the signs will be mounted to a tree larger than three inches in diameter at breast height. The signs must be mounted between four and six feet above the ground surface. Where it is not possible to mount the sign to a tree, a treated wood 4×4 or a metal signpost must be installed. The post must extend below the ground surface at least 24 inches. Again, the signs must be mounted between four and six feet above the ground surface. Signs can be obtained at the Public Works building on Woodman Road.
