Municipal MS4 Non-Consortium Catch Basins and Manholes

The stormwater data was developed to facilitate MS4 reporting. The data developed by Dolph Rotfeld, Bowne Management Systems, and Insite Engineering was captured in 2012. The data developed by various local sources was captured at separate times and is the most up-to-date and complete representation of what is currently in use. The 3 types of features represented in this dataset are ‘Catch Basins’, ‘Drainage Manholes’ and ‘Other’. ‘Other’ represents a location significant to stormwater (i.e., a drainage ditch, etc.), but the attribute data was insufficient, and the source of the data collection could not be contacted to clarify or categorize the data. This layer has been updated in July 2020 to remove all features that were located in MS4 consortium municipalities (17 municipalities are in the consortium in the year 2020). This layer now contains only stormwater catch basins and manholes that are non-consortium.本雨水数据集专为支撑市政分离式雨水下水道系统（MS4，Municipal Separate Storm Sewer System）的报告工作而开发。由多夫·罗特费尔德（Dolph Rotfeld）、鲍恩管理系统公司（Bowne Management Systems）与因赛特工程公司（Insite Engineering）开发生成的数据集采集于2012年。由各类本地来源开发生成的数据集则于不同时段完成采集，是当前在用雨水设施最全面、最新的现状写照。本数据集涵盖三类设施要素：雨水篦子（Catch Basins）、排水检查井（Drainage Manholes）以及“其他”类别。“其他”类别指代对雨水系统具有重要意义的设施点位（如排水沟渠等），但该类别的属性数据存在不足，且无法联系数据采集方以明确其具体分类。本图层已于2020年7月完成更新，移除了所有位于MS4联盟市政管辖区内的设施要素（2020年该联盟共包含17个市政辖区）。目前本图层仅包含非联盟范围内的雨水篦子与排水检查井。
