What material is recommended for pedestrian pathways to maximize infiltration?

Crushed stone is recommended for pedestrian pathways to maximize infiltration due to its porous nature. Unlike more impermeable surfaces like concrete or asphalt, which trap water and reduce infiltration, crushed stone allows rainwater to filter through the gaps between the stones. This promotes groundwater recharge and decreases surface runoff, which can help mitigate flooding and erosion. The open structure of the crushed stone not only facilitates water infiltration but also supports water drainage, thereby maintaining a dryer, more sustainable pathway environment.

This characteristic makes crushed stone an ideal choice in landscape design where permeability is desired, promoting environmental benefits while offering a functional walking surface. The natural appearance of crushed stone can also enhance the aesthetic quality of pathways in various outdoor settings.
