Today, more municipalities are adopting a zero run-off policy for residential development to reduce the potential for downhill flooding from overdevelopment and to help replenish the watershed. One element of that environmental endeavor is to improve the quality of water before it enters the ground and, subsequently, the watershed.
Rain gardens provide natural interaction between soil, vegetation and water to reduce pollutants such as gas, oil, pet waste, road salt, litter, pesticides and fertilizer before entering the ground.
?EUR??,,????'?????<?Development and impervious areas reduce the natural capacity of soil and vegetation to absorb rainfall,?EUR??,,????'?????<? said Chris Cipriano, owner of Cipriano Landscape Design in Ramsey, N.J. ?EUR??,,????'?????<?Traditional stormwater collection for residential properties incorporates 1,000-gallon concrete seepage pits. All impervious areas?EUR??,,????'?????<??oeroofs, driveways, patios and swimming pools?EUR??,,????'?????<??oedepending on the municipal standards, are contained within prescribed seepage pits. Seepage pits are design to reduce flooding and erosion, but do little to control the quality of water that re-enters the watershed.?EUR??,,????'?????<?
A rain garden is a specially landscaped shallow depression that captures and filters polluted stormwater runoff. It provides storage of the bio-filtered stormwater until it permeates the ground and enters the water supply. Plants with deep infiltrating root systems are specifically used in a rain garden design because they must tolerate harsh environments?EUR??,,????'?????<??oedrought to flooding conditions. The organic mulch layer protects the soil from eroding and provides an environment for microorganisms that degrade pollutants.
When designing and installing rain gardens in Mahwah, N.J., landscape architect Bill Moore and Chris Cipriano worked closely with the municipal engineer and the project engineer to formulate a comprehensive approach that allows roof leaders, driveways and patio runoff to be piped into the rain garden. It helps also that the Cipriano owns a 10-acre farm and nursery in Mahwah, N.J. This sustainable solution also costs 10 to 15 percent less than the traditional seepage pit system, which makes it attractive to homebuilders, site work companies, landscape contractors and homeowners.
Adopting sustainable solutions for today?EUR??,,????'?????<???EUR?s environmental issues will result in a shift in attitude that can pass health and wellness along to future generations.
