ResourceProtectionArea

Resource Protection Areas (RPAs) are the corridors of environmentally sensitive land that lie alongside or near the shorelines of streams, rivers and other waterways which drain into the Potomac River and eventually into the Chesapeake Bay. In their natural condition, RPAs protect water quality, filter pollutants out of stormwater runoff, reduce the volume of stormwater runoff, prevent erosion and perform other important biological and ecological functions. RPAs include any land characterized by one or more of the following features: a tidal wetland a tidal shore a water body with perennial flow a nontidal wetland connected by surface flow and contiguous to a tidal wetland or water body with perennial flow a buffer area that includes any land within a major floodplain or any land within 100 feet of a feature listed in 1-4. Development in RPAs is regulated by the Chesapeake Bay Preservation Ordinance, enacted by the Board of Supervisors in 1993.资源保护区（Resource Protection Areas，RPAs）是毗邻或邻近汇入波托马克河并最终注入切萨皮克湾的溪流、河流及其他水道岸线的环境敏感土地廊道。在自然状态下，资源保护区可保护水质、过滤暴雨径流中的污染物、削减暴雨径流量、防止土壤侵蚀，并发挥其他重要的生物与生态功能。资源保护区涵盖具备以下一项或多项特征的土地：潮间湿地、潮岸、常年流水水体、通过地表径流连通且毗邻潮间湿地或常年流水水体的非潮汐湿地，以及包含大型洪泛区内土地或距上述1-4项所列特征地物100英尺范围内土地的缓冲区域。资源保护区内的开发活动受1993年县监事会（Board of Supervisors）颁布的《切萨皮克湾保护条例》监管。
