San Diego Urban communities in San Diego are usually characterized by grid street plans, higher levels of pedestrianism, mixed-use and denser than usual developments. This is in stark contrast to newer, suburban-style, low-density developments elsewhere in the city. They usually surround Balboa Park, and most are located on the mesa north and northeast of downtown ("Urban Mesa"). They also tend to be older, predating the car culture predominant in the city and the state of California today. There has been a resurging interest in reinvesting in these communities in the late 20th century and early 21st century after decades of neglect, especially downtown, and are now facing the challenges of increasing home prices and gentrification.
