As Los Angeles recovers from its devastating wildfires, environmental engineers, urban planners and natural disaster experts are casting forward with visions of what could come next for neighborhoods that have been reduced to ash and rubble.

For more than a century, conservation policy has focused on economic development and wisely using natural resources.

Though many Los Angeles-area parks and museums closed because of air quality or other concerns, several have reopened, including Griffith Park, the L.A. Zoo and Autry Museum of the American West.

At least 29 people are believed to be dead and more than a dozen others remain unaccounted for as multiple wildfires rage across Southern California.
