The document discusses the benefits of density from environmental and economic perspectives, as well as some concerns around gentrification. It provides examples of high density housing in various cities like Portland, San Francisco, and El Cerrito. It suggests that communities use planning charrettes to proactively plan density increases and rezonings to control development. Strategies are outlined to make gentrification more equitable and inclusive. Research is cited showing that higher density neighborhoods with good transit access reduce driving and emissions.

10. All right. Density is good for me and the environment, but I still fear what greedy developers might do to my hood. How can my neighbors and I control them? Use Community Planning charrettes to plan and then rezone before developers propose projects. http://www.charretteinstitute.org/ For instance, the Transbay Area in San Francisco.

We will strive to meet or exceed Kyoto Protocol targets for reducing global warming pollution by taking actions in our own operations and communities such as: 1. Inventory global warming emissions . . . 2. Adopt and enforce land-use policies that reduce sprawl, preserve open space, and create compact, walkable urban communities; 3. Promote transportation options such as bicycle trails, commute trip reduction programs, incentives for car pooling and public transit; . . .
