Low Impact Development or Proper Design

Stormwater professionals inform development and set the stage on how sites should be constructed.  As we design, we should be aware it is documented that traditional design ideas can change downstream hydrology – occasionally causing undesired impacts downstream.  One way to mitigate unintended consequences caused by traditional design is to focus on Low Impact Design.  Low Impact Design or LID has been called many things.  Often times LID is thought of as a trendy, new way to design projects.  The common thought is that LID is a non-traditional design method to be incorporated into a more traditional and conservative design.   But, should this be the case, or should LID be thought of as simply just good site design?  This presentation presents the idea that mimicking natural hydrology to the greatest extent practicable should not be thought of as new and innovative, but rather as the best and most responsible design methodology for treating your neighbor the way you would want to be treated.  The ASCE Manual of Practices and other existing standards of care will be presented as a basis of design.  Additionally, several realistic practices will be presented to serve as first steps towards moving the community in the direction of more sustainable design.  Cost of implementation, maintenance and design considerations will be presented guide the development community to be better neighbors and protect natural resources.
