The embedded map does not work on mobile devices. On a mobile device, the map can be viewed in HSY’s map service.

You can move around the map by zooming in and out and by dragging the map. You can check the location of your property in the stormwater sewerage area by using the property’s address. Open the link to HSY’s map service, enter the address of your property in the Search field in the upper left corner, and press Enter. The map will automatically move to the location of your property.

The basic rate for stormwater must be paid if:

  • your property is located in one of these three areas; or
  • your property has a stormwater connection and your property is located outside the stormwater sewerage area.
