Background

In 1973, the County Council adopted an Adequate Public Facilities Ordinance and granted the Planning Board administrative oversight to ensure that adequate public facilities exist to accommodate growth. Since then, Montgomery County has considered the impacts of development on the transportation system, guided by the County Council’s Subdivision Staging Policy, which is reviewed on a four-year cycle.

The 2017 LATR Guidelines implement the Subdivision Staging Policy to measure development impacts on local roads near the development site.
