Natomas, a community in northwestern Sacramento, is the last area of Sacramento that isn’t fully developed.

This may be about to change, since there are plans to build on fields just southeast of Sacramento International Airport.

The new community could be home to 25,000 people. The plans feature an urban-style community that includes residential and commercial buildings. Early designs include 10,000 dwelling units and retail space that equals the size of five malls.

Concerned citizens are protesting the development, worried that it will affect traffic while threatening wildlife and increasing pollution.
