  • StormwaterPA - The Water Cycle
    at local rivers and streams during a storm can see the effects of runoff Soil that washes off construction sites trash cigarette butts and other litter that has washed from parking lots antifreeze and oil that has dripped from cars and trucks fertilizers and pesticides from golf courses fields and lawns nutrients from agricultural operations grit and salt from de icing roadways all this and more can be flushed directly into waterways when it rains The more we alter the landscape the more we affect the natural cycle and its ability to deal with runoff When we grade and cut and pave and build we re not only causing more polluted water to move into waterways more quickly we re making less water available for absorption into the ground Believe it or not that can affect stream flow and the aquifers we depend on for drinking water in many parts of the state Stormwater 101 Rain in PA Putting Nature to Work In the natural cycle the majority of precipitation falls into the ocean but some hits the ground Of the precipitation that falls on land some is quickly absorbed by the soil some is used by plants and trees

  • StormwaterPA - Rain in PA
    at serious risk Unfortunately these problems aren t limited to major storms they often result from the average rainfall event Human activities have altered the landscape so dramatically that the natural system of stormwater management no longer works The average annual precipitation in Pennsylvania ranges from less than 34 inches to more than 50 inches per year with most coming during small frequent storms Some 65 of the state s average annual rainfall occurs in storms that drop less than 1 inch in a 24 hour period more than 95 comes from storms of 3 inches or less Even though Pennsylvania has been hit by several tropical storms and hurricanes over the past century with devastating results the large 50 year and 100 year storms occur so rarely that they actually account for an insignificant amount of total rainfall volume when averaged out year after year Dealing with rainfall from the many small storm events while planning for the massive volume spikes that do occur during major storms is the key to stormwater management success Stormwater 101 The Water Cycle Runoff Waste or Resource Traditionally we have treated stormwater as a nuisance and past management techniques focused primarily on flood

    plumbing system of conveyances basins and pipes More development meant more such systems all feeding local sewage treatment systems or flowing directly into rivers and streams An increase in impervious surfaces added to the problem by increasing the volume and speeding the rate of stormwater flow Average rain events have become more problematic as the natural systems that once slowed runoff filtered pollutants allowed for infiltration and facilitated transpiration have been replaced by buildings concrete pavement and other non porous surfaces Traditional development techniques tend to treat stormwater as an afterthought whereas low impact development LID considers runoff as an integral part of the natural system from beginning to end Managing Runoff To Improve Water Quality For The Economy To Enhance Quality of Life A Greener Approach The PA Stormwater BMP Manual emphasizes a comprehensive site design approach to land development Whether referred to as Low Impact Development Conservation Design or Green Design this environmentally sensitive approach to site development and stormwater management aims to minimize the negative impacts of development The focus is on prevention and seeks to make the built environment work like nature as much as possible Its goal is to maintain the flood control erosion prevention

  • StormwaterPA - To Improve Water Quality
    in glaciers and ice caps Less than one half of one percent of all of the world s water is fresh water that s actually available for living things to use In Pennsylvania we re blessed with an abundance of natural beauty much of it related to our water resources our landscape is entwined with 83 161 miles of streams and more than 3 900 lakes reservoirs and ponds Water is the lifeblood of the Commonwealth supporting vast forests abundant fish and wildlife and a wide array of human uses that draw more than four billion gallons of ground and surface water per day It s no wonder that water quality is a constant concern or that the negative impacts of stormwater have become such a big deal Managing Runoff For Flood Prevention For The Economy To Enhance Quality of Life Ecosystem Services Reducing imperviousness and maintaining wetlands grasslands and other vegetated areas helps buffer the effects of stormwater runoff Plants roots soil and leaf litter trap sediments debris and particulates that would otherwise make their way into waterways When we enable infiltration we facilitate the recharge of the aquifers and groundwater supplies that flow into the rivers we use

  • StormwaterPA - For The Economy
    reduce the amount of downstream sedimentation This reduces the cost of dredging and water treatment while increasing recreational opportunities and business and residential property values Taking a site planning approach that maintains or restores wetlands rather than removing them controls and treats wastes reduces flooding and improves habitat for wildlife and aquatic species Minimizing stormwater runoff can prevent costly investment in sewage treatment infrastructure to deal with excessive flows reaching combined sewers The resulting effective treatment of human and industrial waste protects rivers beaches and human health Innovative stormwater management techniques help developers save money by replacing pipes basins and other infrastructure with less costly BMPs by minimizing land clearing and grading costs and by using less land area for stormwater management than required by traditional basins Low impact development or LID is often less expensive than conventional development because clustering can reduce the cost of maintenance and municipal services such as sewer and water trash removal lighting and street maintenance Low impact development can also increase property values and marketability because of natural landscaping open space wetlands and waterways With researchers estimating that population growth in the U S will add more than one million new single family homes and some 10 000 miles of new roadways to the landscape every year over the coming decade the potential savings and value added by proper stormwater management is hard to ignore Managing Runoff For Flood Prevention To Improve Water Quality To Enhance Quality of Life By The Numbers Trees reduce energy costs clean air and water and help protect human health Over a 50 year period it is estimated that the average tree provides 30 000 worth of oxygen 35 000 worth of clean water and 60 000 worth of air pollution removal Researchers at the University of California at
