What types of permits do I need from the County versus municipality for a project located in a municipality in Prince George’s County?

Municipalities are shown on PGATLAS. Once you are on the page, select "Map Layers" (the last icon on the right). View the list of choices, then click on the drop-down menu by "Administrative" Layer; next, move the slider down on the right to view and click on the "Municipal Boundary" layer.
