[[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!]] | [[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]].
