Based on the massive master-planned California neighborhood of the same name, Aurora's Mission Viejo neighborhood was constructed from 1972 to 1985, though some construction following the original master plan continued until 1992. The neighborhood utilizes a rose pattern layout, underground utilities, and unobstructed green spaces and walking trails - all unique features at the time of construction. Spanish-inspired Mission architecture is evident in the replica adobe "slump" walls and entrances as well as the homes, which featured exposed external timbers, arched doorways and windows, balconies, and walled courtyards. The neighborhood also integrated schools, libraries, fire stations and shopping into the neighborhood, which featured Mission-style architectural embellishments. Mission Viejo Aurora has received national recognition for superior design and environmental improvement.
