Navigate to Portland Maps and search for your property. In the right panel, scroll to the Utilities section. Click ‘Sewer Assets’ to see the public sewer and stormwater infrastructure near your property and to open a new set of options in the sidebar, where you can view the different line (e.g. pipe) and node (e.g. manhole) assets to gather more information about their physical attributes. You can also see project and as-built plans (where available) in the ‘Jobs’ section, look at maintenance service requests, and view historic sewer board maps. If a City record is not available on Portland Maps, you can request it from Portland’s Archives & Records Management department.
To research historic building and plumbing permits for your property, scroll to the Permits & Zoning section in the right panel and click ‘Permits’. Further permit research tools and information are available on the BDS Public Records Access website.
