Local questions before drainage or excavation work
Columbiana: the city publishes a residential building and zoning review process. Ask which review applies to your proposed excavation, drainage or structural work and who will handle it. Start with the City of Columbiana residential building guidance; do not assume a city procedure applies outside its jurisdiction.
Salem: use the Salem Utilities Department for municipal water and sanitary-sewer questions. If a contractor proposes changing a discharge route or sewer connection, have the destination and responsible authority identified in writing before work starts.
East Liverpool, East Palestine, Lisbon and Wellsville: confirm the authority for your exact property before accepting a permit or discharge assumption. The Columbiana County Health District plumbing page provides permit information and a registered-plumber resource. Ask whether its process applies to your address and proposed plumbing component; a county resource is not proof that every waterproofing repair requires the same permit.
