Cities are never finished. They continue to evolve and adapt to change. The urban design of a city is the sum of organic and planned public spaces that have formed over time in its streets, riverfronts, plazas, and neighborhood parks. These spaces are formed and activated by the the uses housed in both public and private buildings that frame them. They serve as the enabler of the city’s economy and the backdrop for the city’s vitality, character, and livability.
