Parking

The CMS complex has approximately 3,100 parking spaces which provides sufficient parking for all. Parking lots are fairly level, with handicap curb cuts in each lot. Spaces are designated for persons with disabilities, car pools, and government vehicles. Numbered reserved parking spaces and government vehicle parking spaces are reserved 24 hours a day, 365 days a year and are issued a specific hangtag for use in those sections.

A visitor's parking area is also designated. Each visitor is required to obtain a permit from the main entrance guard station (Security Boulevard) as they pull into the parking lot. The permit must be placed on the dashboard on the driver's side and be visible to the guards at all times.

Any driver entering the complex without a valid CMS parking hangtag is required to obtain a 1-day temporary parking permit from the guard station. The permit must be placed on the dashboard on the driver's side and be visible to the guards at all times.

Visitors who experience problems with their car must contact a uniformed Security guard, or call the Security Control Center on 410-786-2929 for assistance. Visitors' vehicles are not allowed to be parked overnight on CMS's campus.

You must be a United States (U.S.) citizen, a U.S. national, or have a satisfactory immigration status to be eligible for full benefits.
