Why did Springfield update the Plan?
Springfield updated the Plan for a number of reasons: the two older, existing plans are out of date, and new strategies and technologies are available for developing a plan and dealing with stormwater. The new approaches emphasize using open waterways, like sloughs and swales, to improve water quality and reduce flooding. This is part of a comprehensive approach the City is taking to manage its water resources sustainably and responsibly. New federal and state rules also require the City to evaluate how stormwater is managed, and develop strategies to improve water quality.
What are stormwater facilities?
Stormwater facilities are engineered structures designed to convey storm runoff, remove pollutants, and control flow rates. Facilities include pipes, ditches, swales, and retention/detention ponds. Many new catch basin and storm drain designs are now available to help mechanically remove contaminants and clean runoff.
Why is stormwater runoff a problem?
As we develop land, clear woodlands, pave roads and parking lots, and put up new buildings, the ground is no longer as permeable as before the development. This means that the rain can not infiltrate into the ground as readily, and causes more higher stormwater flows through the storm system and, occasionally, over land. Unmanaged stormwater runoff can cause flooding and erosion problems, negatively impact water quality and degrade stream habitat.
What are the benefits of stormwater facilities?
Stormwater facilities help prevent flooding and erosion problems by capturing and moderating storm runoff. They protect water quality by incorporating features that filter or remove sediments, excess nutrients and toxic chemicals. Some facilities enhance open space and provide habitat for fish, birds and animals. Groundwater recharge, necessary for maintaining domestic wells and summer stream flows, is also enhanced.
