2011 Map of Sandy Spring

About this map

Olney Town and the neighboring village of Brookeville anchor this landscape during a period of significant suburban development in Montgomery County. The map documents a dense network of residential subdivisions such as Olney Mill, Tanterra, and Manor Oaks, which have expanded around older rural landmarks like the Salem United Methodist Cemetery. To the north and east, the terrain remains defined by the Patuxent River and the expansive Tridelphia Reservoir, controlled by the Brighton Dam. This 2011 survey captures the area's transition, where family-named landholdings like Kalmia Farms and Park Overlook Farm sit adjacent to modern amenities like the Blue Mash Golf Course and Norbeck Golf Course. Historical continuity is maintained through the various post offices serving Ashton, Sandy Spring, and Brinklow, while the name Gold Mine Crossing hints at the region's earlier industrial ventures.
