What is low impact development plan?
Low Impact Development (LID) is a stormwater management strategy that emphasizes conservation and the use of existing natural site features integrated with distributed, small-scale stormwater controls to more closely mimic natural hydrologic patterns in residential, commercial, and industrial settings.
How do you design low impact development?
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 the low impact development lid program?
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 is low impact urban development?
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. …
What are the key features of low impact development?
The key premise of low impact development (LID) is to allow natural systems to manage stormwater when and wherever possible. LID takes advantage of existing natural features and also designs and constructs systems to imitate natural processes, for example, green roofs, bioretention gardens, and permeable pavement.
What is the most sustainable goal of low impact development?
The primary goal of LID is to mimic predevelopment hydrology of a given development site. This is achieved by maximizing site design techniques that intercept, evaporate, filter, store, and infiltrate runoff.
What is a lid BMP?
Structural LID-BMPs include various types of basins, filters, surfaces, and devices located on individual lots in a residential development or throughout a commercial, industrial, or institutional development site in areas not typically suited for larger, centralized structural facilities.
What is lid and green infrastructure?
Low impact development (LID) is an approach to stormwater management that mimics a site’s natural hydrology as the landscape is developed. Green infrastructure is an approach to wet weather management that is cost-effective, sustainable, and environmentally friendly.
Why is low impact development important?
When implemented broadly, LID can also mitigate the urban heat island effect (by infiltrating water running off hot pavements and shading and minimizing impervious surfaces), mitigate climate change (by sequestering carbon in plants), save energy (from green roofs, tree shading, and reduced/ avoided water treatment …
Why do we need low impact development?
Low impact development treats stormwater as a resource rather than a waste product. These practices ultimately improve the quality, and decrease the volume, of stormwater entering our waterways.
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 the two main objectives of low impact development?
Key principles of this approach include reducing impervious cover, increasing the amount of natural lands set aside for conservation, and better integrating stormwater treatment systems on-site.
