In July 2019, Jeff Cox and Wayne McCready met with Alex Baquie to discuss a detailed workplan to resolve errors generated by Route Completion Reports during snow events in recent years. BOH GIS Intern Adam Mills was then tasked with following this workplan. The geodatabase file as well as the ArcMap MXD file were created by Jeff Cox and Wayne McCready ahead of time in order to get the project done faster. Included in geodatabase was a point layer containing the errors, a layer containing the path of snowplows, and the Snow Route District boundaries layer. In order to remove error points that were classified as falling in "Other Jurisdictions" polygons, the polygons were cut so that the road no longer lies within the polygons outside of Anne Arundel County Jurisdiction. The next step was to merge the cut polygons with the adjacent district polygons. For the points that fell on district lines, they were turned into pdfs and sent out to district managers so that they could provide feedback on how they wanted the polygons edited. Once the feedback was received the polygons at each trouble area was cut so that the road no longer fell on the district boundary, and was then merged with one of the adjacent district polygons. Then a feature dataset was created within the geodatabase, in order to create a topology of the snow removal polygons layer, in order to ensure no overlaps or gaps were present in the layer.</SPAN></P><P><SPAN>The boundaries were updated and renamed to accommodate the 2023 District Realignment by Rachel Antonio in March 2023 as follows: Northern to "Eastern," Central to "Western", St. Margarets yard switched from Central to Eastern, Snow Zone N12 realigned to Western Millersville. Additional boundary changes were made in August 2024 to Snow Removal Zones EM 7 to move from Mountain Rd to St. Maragrets yards.</SPAN></P></DIV></DIV></DIV> Anne Arundel County Department of Public Works Bureau of Highways Snow Removal Zones Snow Route Districts Maintained by DPW BOH IMD GIS (Wayne McCready and Jeff Cox) since 2015. Topology edits made in 2016. Major boundary edits made to Southern District in 2017. Major boundary edits made to Central and Northern Districts in 2018. Minor boundary changes in each District in August 2019. Some were requested by the Districts.
