Development Pipeline

Pipeline of Approved Development

Montgomery County, Maryland

The Montgomery Planning Department tracks the residential and non-residential Development Pipeline for Montgomery County planning areas and municipalities (Gaithersburg, Laytonsville, Poolesville, and Rockville). The pipeline is an inventory of development projects that have been approved by the Montgomery County Planning Board but not completely built. This inventory covers unbuilt dwellings units and unbuilt non-residential building gross square footage.

The projects tracked for the pipeline include preliminary plans that add development and site plans that do not have a parent preliminary plan to represent the project; these are known as standalone site plans. Various precursors to the approval of a preliminary plan or a standalone site plan, such as sketch plans, Natural Resource Inventory approval, and forest conservation plans, are not part of pipeline tracking. Furthermore, not every preliminary plan is tracked in the pipeline, as many are amendments that do not alter the quantities of development.

For the projects tracked in the pipeline, residential dwelling units are further categorized into single-family dwellings and multi-family dwellings. Approved commercial gross floor area is further categorized as office, retail, industrial, or institutional. These approved spaces are also listed by the number of jobs expected to be associated with those approvals. 

January 2025: Pipeline by Master Plan

If you unhide columns “A” through “F” you can manipulate the data by master plan, policy area, traffic zones, submittal date, and Adequate Public Facility (APF) expiration date.
