Cities are not separate from nature – they are part of it. This chapter explains how planners protect natural resources, create parks and open space, and help communities adapt to environmental challenges like flooding and heat waves.
The chapter begins with green infrastructure. Instead of relying solely on pipes and concrete, planners use rain gardens, permeable pavement, green roofs, and constructed wetlands to manage stormwater. These techniques reduce flooding, filter pollution, and cool neighborhoods – all while being cheaper than traditional sewers.
Parks and recreation are not luxuries; they are essential public health infrastructure. The chapter discusses park equity – ensuring that every neighborhood has a safe, clean park within a 10‑minute walk. Planners use tools like park impact fees (charging developers to fund new parks) and conservation easements (protecting land permanently).
Open space networks connect parks, trails, and natural areas into a continuous system. These corridors allow wildlife to move, give residents long routes for walking or biking, and can even serve as emergency evacuation routes.
The chapter also addresses climate change planning. Coastal cities must plan for sea‑level rise. Inland cities face more intense storms and droughts. Planners use hazard mitigation plans to identify risks and develop strategies: buyouts for flood‑prone properties, cooling centers for heat waves, and fire‑adapted landscaping in the wildland‑urban interface.
A powerful theme is that protecting nature is not anti‑development. In fact, preserved open space raises property values, attracts businesses, and improves quality of life. The chapter urges planners to think of natural systems as infrastructure – as vital as roads and water pipes.
