New! Address Verification

Contractors and Howard County residents are permitted to use the Alpha Ridge Landfill and Residents’ Convenience Center. Traditionally staff have used Maryland Driver’s Licenses to confirm Howard County residency. Because the new Maryland Driver’s Licenses no longer indicate the county of residence, staff may enter your address into an address checker to confirm residency. The address checker is a publicly available app developed for DPW and the Health Department. It uses an address listing, maintained by Department of Fire and Rescue and the 911 Center. The application does not track number of visits, material type, date or weight.
