What is Storm Water Management?
When it rains or snows, the amount of water that is absorbed back into the environment varies largely on whether the land is paved or natural. Rain and snow on natural or undeveloped land gradually infiltrates into the soil, replenishing groundwater supplies and slowly discharging excess runoff to local waterways. In contrast, as we pave roads and sidewalks, construct buildings or add other impervious surfaces, the amount of water that can be naturally absorbed after a rain or snow event is reduced drastically.
Water that cannot infiltrate into the surrounding environment is called runoff. In order to prevent our communities from flooding, runoff is diverted into the "storm drainage system" (a network of structures, channels and underground pipes that carry storm water (rain water) to ponds, creeks, streams and rivers).
As part of the City's MS4 General Permit to manage storm water, Public Works wants to provide information and help educate residents on storm water related issues. Public Works aims to raise awareness of the effects of storm water pollution and help educate residents on how they can be part of the solution.
