Growth Tiers

The Growth Tiers identify where major and minor residential subdivisions may develop and the type of sewage disposal system that will serve them. A parcel divided into four or more lots is considered a major subdivision in Baltimore County. Our Growth Tiers were developed in response to Maryland’s Sustainable Growth and Agricultural Preservation Act of 2012 (SB 236). Existing geographic data such as existing and planned sewer areas, zoning, URDL, and a variety of conservation/preservation layers of were analyzed (PDF) and used to classify County land into one of four Growth Tiers:

Tier I: Major or minor subdivisions served by public sewers are allowed.
Tier II: Major or minor subdivisions served by public sewers are allowed. Minor Subdivisions on individual on-site disposal systems shall be viewed as interim.
Tier III: Major subdivisions on individual on-site disposal systems are allowed, with the recommendation of approval by an approving authority. Minor subdivisions on individual on-site disposal systems are allowed.
Tier IV: Only minor subdivisions on individual on-site disposal systems are allowed.

The adoption letter (PDF) and poster of the adopted map (PDF) are available and citizens may also view the Growth Tiers in the "Land Development" tab of Baltimore County's My Neighborhood interactive map.
