What is low impact development plan?
Low-impact development (LID) is a term used in Canada and the United States to describe a land planning and engineering design approach to manage stormwater runoff as part of green infrastructure. LID emphasizes conservation and use of on-site natural features to protect water quality.
What are examples of low impact development?
The most common examples of Low Impact Development are rain gardens, bioretention gardens, bioswales, pervious pavement, green roofs, and rain harvesting.
What are two low impact development or lid solutions to reducing stormwater runoff?
LID practices include; bioretention facilities or rain gardens, grass swales and channels, vegetated rooftops, rain barrels, cisterns, vegetated filter strips, and permeable pavements.
What are low impact development techniques?
The term low impact development (LID) refers to systems and practices that use or mimic natural processes that result in the infiltration, evapotranspiration or use of stormwater in order to protect water quality and associated aquatic habitat.
What is low impact development stormwater?
Low impact development (LID) is a stormwater management strategy that seeks to mitigate the impacts of increased runoff and stormwater pollution by managing runoff as close to its source as possible. For preservation, it uses site design strategies to minimize runoff and to protect natural drainage patterns.
How do you achieve low impact development lid?
There are 5 core requirements when it comes to designing for LID.
- Conserve natural areas wherever possible (don’t pave over the whole site if you don’t need to).
- Minimize the development impact on hydrology.
- Maintain runoff rate and duration from the site (don’t let the water leave the site).
What is LID plan?
A LID Plan is a document developed to control pollutants, pollutant loads, and runoff volume being released from the project site by minimizing the impervious surface area and controlling runoff from impervious surfaces.
What are lid plans?
What are lid strategies?
Low Impact Development (LID) is an alternative site design strategy that uses natural and engineered infiltration and storage techniques to control storm water where it is generated.
What is low impact development stormwater management?
Low impact development (LID) means an approach to stormwater management that mimics a site’s natural hydrology as the landscape is developed. Using low impact development approach, stormwater is managed on-site and the rate and volume of predevelopment stormwater reaching receiving waters is unchanged.
What are the chapters in low impact development site planning?
Chapter 1. Introduction Chapter 2. Low-Impact Development Site Planning. The site design philosophy and site planning techniques are described and illustrated in this chapter. Chapter 3. Low-Impact Development Hydrologic Analysis.
How do you plan a 2 15 low impact development?
LID Site Planning 2-15 Low-Impact Development: An Integrated Environmental Design Approach •Increase and lengthen flow paths. •Lengthen and flatten site and lot slopes. •Maximize use of open swale systems. •Increase and augment site and lot vegetation. Overland Sheet Flow.
What is stormwater management and green infrastructure?
Stormwater management: Low-impact development and green infrastructure. Green infrastructure management approaches and technologies infiltrate, evapotranspire, capture and reuse stormwater to maintain or restore natural hydrologies. The terms “low impact development” and “green infrastructure” are used interchangeably.
