Under a County Council bill proposed earlier this week, you may be seeing some bigger names in downtown Towson. Literally.

The new bill, introduced Monday by Councilman David Marks, carves out zoning exceptions for certain building signs in Towson.

The bill creates a new class of "enterprise" signs that developers could place on a wall, canopy or roof of any development with at least 150,000 square feet of floor space in the Towson commercial district.

The bill also clarifies that signs on county and state properties in Towson, such as the electronic billboard on the Towson library or future signage on the Baltimore County Revenue Authority property, are exempt from county zoning rules.

"There's always been some ambiguity and I just wanted to make clear that the library, for example, could have that kind of signage," Marks said.

The legislation was requested by Caves Valley Partners, owners of Towson City Center, who contend "this was needed to help attract  the kind of tenants that they want," Marks said.

The building is currently being refurbished and is set to open in 2012 with tenants that include Mile One Automotive and Towson University. Mile One plans to use the top floors as its new headquarters, and if the new regulations are approved, they could theoretically put a sign on the building. Marks called the deal a trade-off.

"Yes, there'll be more signage," he said. "But on the other hand, you get a more valuable project."
