Low Impact Development
In every development, stormwater must be examined. In some cases, a homeowner can simply disperse their roof drains into their yard, and in other cases more serious measures are required. Every time stormwater is handled on a property - private, commercial, city or county owned, that stormwater flows downstream to another property and eventually to one of the major bodies of water around us. Here in the Puget Sound area, that major body of water IS the Puget Sound. We have a responsibility to ensure that the water we let flow back into the environment is clean and free of pollutants. That's where low impact design is important.
In order to minimize the need for expensive pipes, basins, and other classic methods of conveying stormwater, alternatives have been developed by engineers and scientists to mimic the natural features we find in nature. These features not only reduce the amount of water that we send into storm pipes, but they also help recharge the groundwater table, filter and clean the runoff from roadways, and reduce flooding from large storms. Most low impact features are also a good way to beautify a piece of property - features typically include native trees, shrubs, flowers, and other plants that naturally thrive in wet soils.
We typically look for LID (Low impact Development) methods for solving stormwater issues on any project before resorting to the classic style of dealing with stormwater. The Puget Sound Partnership is one of the leading organizations in Washington dedicated to the preservation and rehabilitation of the Puget Sound - and each project that implements an LID feature puts us one step closer to realizing that goal.
