Critical Areas

The purpose of the Chesapeake Bay Critical Area (CBCA) Remapping effort is to provide an updated critical area map for the Counties of Maryland. This layer has been approved and is the official Critical Area Boundary for Anne Arundel, Maryland (adopted October 2021) and was adopted by the Anne Arundel County Council on July 19, 2021 (Bill 63-21). This data layer contains the new critical area boundary and corresponding designations derived from shoreline and wetlands digitized from 2007/08 aerial imagery and CIR. A 1000' buffer of the shoreline and wetlands generated the proposed critical area boundary. Critical area designations (IDA, LDA, RCA, etc) were pulled from the current designation layer and fit to the new boundary. Extensive discussions with County officials and Critical Area Commission resulted in a complete review of designations. Updated with Case No 2015-0257-G 12/25/2015. Update with Bill No 43-16 2016-0002-G on 10/1/2016. Correction to layer from mylar on 8/30/2018 - Bill No. 30-94. Correction to layer on 2/27/2023 from an approved Growth Allocation (April 7, 2015) for 6054 Drum Point Rd.切萨皮克湾关键区域（Chesapeake Bay Critical Area，缩写CBCA）重绘项目的目标是为马里兰州各郡县提供更新版关键区域地图。本图层已获正式批准，为马里兰州安妮阿伦德尔县的官方关键区域边界（2021年10月正式通过），并于2021年7月19日经安妮阿伦德尔县议会审议通过（法案编号：63-21）。本数据图层包含全新的关键区域边界及对应区划信息，其基于2007至2008年航空影像与彩色红外影像（CIR）数字化提取的岸线与湿地数据生成。通过对岸线及湿地构建1000英尺缓冲区，生成了拟议的关键区域边界。关键区域区划（如IDA、LDA、RCA等）取自现有区划图层，并适配至新边界。项目团队与郡县官员及关键区域委员会开展多轮磋商，完成了对所有区划的全面复核。本数据曾于2015年12月25日随案件编号2015-0257-G完成更新；2016年10月1日随法案编号43-16（编号2016-0002-G）再次更新；2018年8月30日针对聚酯胶片载体的图层进行修正（法案编号：30-94）；2023年2月27日针对2015年4月7日批准的6054号德拉姆点路地块增长分配方案对应的图层完成修正。
