    Appendix A Low Impact Development Practices. ALTERNATIVE APPROACH FOR MANAGING STORMWATER RUNOFF. Natural hydrologic conditions may be altered radically by poorly planned development practices, such as introducing unneeded impervious surfaces, destroying existing drainage swales.   Urban development significantly alters the natural landscape of Canadian communities, creating hardscape surfaces that prevent infiltration of water into soil surfaces and the subsequent increased runoff. These impervious surfaces disrupt rainwater from soaking into the ground, causing it to run across parking lots and streets, where it collects used motor oil, .

      Urbanization has led to a substantial change in the hydrological cycle of urban catchments. Increased runoff and urban flooding, decreased direct subsurface infiltration and groundwater recharge, deterioration of water quality are among the major effects of this alteration. To alleviate these effects, Low Impact Development (LID) practices have been frequently Cited by: 4. Low Impact Development Urban Design Tools The LID Center, Inc., site provides design specifications, technical diagrams, and cost-sheets for LID techniques including bioretention, green roofs, permeable pavements, rain barrels and .

    Planners, designers, citizens, and governmental agencies are interested in measuring and assessing urban design treatments that are environmentally sensitive across numerous environmental design issues such as stormwater, adapting to climate change, wildlife suitability, visual quality, and maintaining soil productivity. This chapter examines a case study in the Cited by: 1. Case study of the Document. About The writer. Low-Impact Development Hydrologic Analysis is a document purposely used to provide low-impact development (LID) hydrologic analysis and “computational procedure used to determine low-impact development storm water management requirements” (p. 1).

The remaining low-impact development hydrologic analysis techniques are based on the premise that the post-development Tc is the same as the pre-development condition.

If the post-development Tc does not equal the pre-development Tc, additional low-impact development site design techniques must be implemented to maintain the Tc.

It has been hypothesized that LID can be used to restore predevelopment hydrology. Get this from a library. Low-impact development hydrologic analysis: companion document to The low-impact development design strategies. [Prince George's County (Md.). Department of Environmental Resources.

Abstract: The quality and quantity of residential stormwater runoff from a control, traditional, and low impact development (LID) watershed were compared in a paired watershed study. A traditional neighborhood was built using typical subdivision standards while a LID design was constructed with best management practices including grass swales, cluster housing, shared Cited by: A acre subwatershed of a local subdivision was adapted to LID using impervious surface disconnection, forest retention, and IMPâ s.

SWMM was applied to the LID development at a fine spatial scale, yielding an element SWMM model. The LID model was modified to reflect conventional development, with gutters, storm sewer, and by: all of the hydrologic impacts of development. Detention facilities do not mitigate seasonal volume shifts, wetland water level fluctuations, groundwater recharge reductions, or base flow changes.

Such impacts can be further reduced through the use of Low Impact Development (LID) techniques, beginning with careful.

Low Impact Development (LID) principles and applications have been developed to mitigate the impact of imperviousness in urban areas on storm water runoff for both quantity and quality aspects.

In particular LIDs are designed to mimic the pre-development hydrologic conditions thus promoting storage, infiltration and evapotranspiration processes Cited by: Case study of the Document.
