As California and several other states have recently found out, water conservation is a huge deal to resident’s quality of life and the environment’s overall health.  Allowing water to drain naturally is a huge part of keeping our aquifers filled with water, but our roadways and parking surfaces are mostly impermeable surfaces, causing us to redirect rainfall unnaturally into drains and sewers. Sudden and large amounts of rainfall in a short period of time can lead to extremely hazardous conditions, like flooding.
