NeighborSpace has nine properties within the Urban Rural Demarcation Line, a line that separates Baltimore County into two pieces, an area closer to the city that has the infrastructure for development and a rural area that does not, helping to keep it for lower density residential development and agricultural use.

The line was established in 1967, according to a history of master planning in Baltimore County, to help manage growth while protecting the county's natural and agricultural resources.

Though the land between the URDL and the city makes up only 30 percent of the county's total area, it contains 90 percent of the county's population, according to a release from NeighborSpace.

According to a release from NeighborSpace, "Baltimore County has two distinct land management areas, an urban area bordering Baltimore City, where the provision of public water and sewer infrastructure is an incentive to development, and a rural area that lacks this infrastructure, in order to discourage development."
