The document discusses low impact development (LID) as a more sustainable approach to land development and stormwater management that aims to mimic natural hydrology. It outlines various LID techniques like narrower streets, bioretention areas, permeable paving, green roofs, and rain barrels that can reduce runoff and treat pollutants on-site in a decentralized manner. Implementing LID provides environmental, community, and local government benefits like protecting water resources, reducing infrastructure costs, and preserving open spaces.
