Porous concrete is seeing increased use as a means to return sur-
face runoff to the ground, rather than directing it for disposal via a
municipal storm water system. In the example of porous concrete use
shown in Figure 14.24, a new walk that crossed near the base of an older
Live Oak resulted in minimal impact on the surface root system and, at
the same time, provided moisture where encroachment of paved sur-
faces were threatening the health of the tree.
