MS4 Data, Mobile & Online Mapping

H2M managed the creation of a GIS database for mapping the Storm Water assets for the Storm Water Consortium of Rockland County, which is comprised of 23 municipalities in the County. H2M, leveraging Esri’s ArcGIS Online, hosted a data website which provides access to a centralized web mapping system. H2M also developed a mobile application using Esri’s Collector for ArcGIS to assist the 23 Towns/Villages in the collection of field data for the compilation of information on the Storm Water assets to satisfy the requirements of the NYS SPDES MS4 program. Combining the original data collected from existing storm water system maps and the additional field work to identify storm water outfall locations, the project will result in a comprehensive mapping of the municipal separate storm sewer systems (MS4).

Other MS4 GIS clients include:

  • Inc. Village of Bayville, NY
  • Inc. Village of Woodbury, NY
  • Inc. Village of Lloyd Harbor, NY
  • Inc. Village of Port Washington North, NY
