What do CALGreen permeable paving requirements aim to address?

CALGreen permeable paving requirements primarily aim to address storm runoff management. These regulations are designed to mitigate the negative impacts of increased impervious surfaces created by urban development. By allowing water to permeate through pavements, the requirements help to reduce stormwater runoff, thereby decreasing the risk of flooding and erosion, improving water quality, and enhancing groundwater recharge. This approach aligns with sustainable design principles, promoting environmental benefits while minimizing the burden on drainage systems.

While other factors such as construction costs, aesthetic considerations, and urban planning needs play a role in landscape architecture, the central focus of CALGreen’s permeable paving criteria is to effectively manage stormwater runoff. This reflects a growing emphasis on sustainability and the need to incorporate practices that address environmental challenges in urban settings.
