​Our Organization​

Through Planning Services, the Maryland Department of Planning completes more than 200 technical assistance projects for counties and municipalities in a typical year. Planning services provides support in reviewing or drafting more than 60 comprehensive plans and/or ordinances for local governments each year. It also collects, analyzes and publishes social, economic and geographic information and maintains the digital maps of the state’s 2.3 million parcels.

The Maryland Department of Planning coordinates the State Data and Analysis Center (SDAC) in Maryland. SDAC monitors development trends, analyzes social, economic and housing characteristics, and prepares population, household, labor force, and employment projections, which provide the baseline for planning for growth and development in the State. SDAC is an official partner with the U.S. Census Bureau. SDAC creates and enhances several planning-related GIS layers that are used​​ in analytical tools and processes to provide the public, local and state officials, and decision makers with timely and accurate data and analysis. SDAC maps tax assessment account locations for the State of Maryland, produces paper and digital tax assessment maps for Maryland and publishes statewide data on real property sales, parcel accounts, and detailed real property characteristics in a geographic information system (GIS) compatible format.


Finance & Operations is responsible for the administrative support for the department such as financial, information technology, procurement and logistics. The communications section coordinates outreach to promote the department’s initiatives and services in order to develop and strengthen relationships as well as support the administration’s legislative and policy initiatives. The unit also focuses on educational opportunities as part of our outreach and administers grants.

The Maryland Historical Trust (the Trust) is dedicated to preserving and interpreting the legacy of Maryland's past. The Trust serves as Maryland's State Historic Preservation Office (SHPO) and provides direct assistance to a broad base of local, state and federal stakeholders in the identification, protection and enhancement of heritage resources. The Trust administers a variety of historic preservation grant, loan, and tax credit programs including the Sustainable Communities Tax Credit which leverages private investment in the rehabilitation of both commercial and residential historic properties. The Trust also administers and oversees operations of the Jefferson Patterson Park and Museum in Calvert County, which includes the Maryland Archeological Conservation Laboratory.
