Metropolitan strategy & structure
Guided desert metropolis growth
MEDSTAR, the Metropolitan Development Strategy for the Arriyadh Region, was prepared in the mid-1990s by the Arriyadh Development Authority (later the Royal Commission for Riyadh City) to guide the long-term growth of the Saudi capital. It combined a fifty-year strategic vision with a structure plan directing expansion along defined corridors, protecting wadis and setting phased urban growth boundaries, and it addressed transport, infrastructure and sub-centre development for a rapidly growing desert metropolis of several million people.
MEDSTAR is one of the most substantial metropolitan strategies produced in the Gulf, notable for introducing growth-boundary and corridor concepts to a city expanding at exceptional speed. It provided the planning armature for later investments such as the Riyadh Metro and informed subsequent Saudi metropolitan planning practice. It also illustrates the tension, common across the region, between formal strategic frameworks and land-market dynamics driven by large-scale peripheral subdivision.
