Low-impact Development - Five Principles of Low Impact Development

Five Principles of Low Impact Development

There are 5 core requirements when it comes to designing for LID.

  1. Conserve natural areas wherever possible (don’t pave over the whole site if you don’t need to).
  2. Minimize the development impact on hydrology.
  3. Maintain runoff rate and duration from the site (don’t let the water leave the site).
  4. Scatter integrated management practices (IMPs) throughout your site – IMPs are decentralized, microscale controls that infiltrate, store, evaporate, and/or detain runoff close to the source.
  5. Implement pollution prevention, proper maintenance and public education programs.

Famous quotes containing the words principles, impact and/or development:

    “Amidst the downward tendency and proneness of things, when every voice is raised for a new road or another statute or a subscription of stock; for an improvement in dress, or in dentistry; for a new house or a larger business; for a political party, or the division of an estate;Mwill you not tolerate one or two solitary voices in the land, speaking for thoughts and principles not marketable or perishable?”
    —Ralph Waldo Emerson (1803–1882)

    “One can describe a landscape in many different words and sentences, but one would not normally cut up a picture of a landscape and rearrange it in different patterns in order to describe it in different ways. Because a photograph is not composed of discrete units strung out in a linear row of meaningful pieces, we do not understand it by looking at one element after another in a set sequence. The photograph is understood in one act of seeing; it is perceived in a gestalt.”
    —Joshua Meyrowitz, U.S. educator, media critic. “The Blurring of Public and Private Behaviors,” No Sense of Place: The Impact of Electronic Media on Social Behavior, Oxford University Press (1985)

    “I can see ... only one safe rule for the historian: that he should recognize in the development of human destinies the play of the contingent and the unforeseen.”
    —H.A.L. (Herbert Albert Laurens)
