[[File:LID Salt reduction.png|thumb|500px|The above graph shows research conducted by the STEP group comparing the chloride level discharges between asphalt, and two commonly used LID practices ([[Permeable pavement]] and [[Bioretention]]. The results show that asphalt releases salt in concentrated bursts during winter whereas the LIDs release it more gradually over the entire year, thus the level of chloride entering into receiving to streams from PP and Bioretention are much lower!]]

Since salt has deleterious effects on many plant species, there is often concern that [[plants]] in LID receiving salt laden road runoff will not fare well over time.  Several design features are meant to address these risks, including:
