What are three examples of low impact design practices?

There are many practices that have been used to adhere to these principles such as bioretention facilities, rain gardens, vegetated rooftops, rain barrels and permeable pavements.

How do you design 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).

What are the five most common low impact development lid methods used for stormwater management in Canadian cities?

The most commonly adopted stormwater LID practices include the following:

• Bio-retention/Rain Gardens.
• Permeable Pavements.
• Soakaways, Infiltration Trenches and Chambers.
• Green Roofs.

What is low impact urban development?

Low Impact Development (LID) is an approach to land development that works with nature to manage stormwater runoff where it falls. LID preserves and recreates natural landscape features, and minimizes hard surfaces to create functional and appealing site drainage.

What do you need to know about low impact development?

Low Impact Development (LID) is defined as “an innovative land planning and design approach which seeks to maintain a site’s pre- development ecological and hydrological function through the protection, enhancement, or mimicry of natural processes.” There are many reasons to use LID, but stormwater management is typically the primary one.

How are LID sites used in low impact development?

The building footprint and circulation are identical in each. The LID site design addresses the unique conditions of the site and uses an arrangement of distributed LID controls to meet storm water management requirements. It also utilizes the existing wetlands to function as a natural filtration zone,…

What are some examples of low impact development technologies?

Low-tech vegetated areas that filter, direct, and retain storm water such as rain gardens and bio-swales; Innovative materials that help break up (disconnect) impervious surfaces or are made of recycled material such as porous concrete, permeable pavers, or site furnishings made of recycled waste;

What’s the difference between GSI and low impact development?

GSI, on the other hand, refers to and relies on the physical elements (natural or man-made) of the landscape when addressing or minimizing impacts from stormwater runoff. In other words, LID is a series of planning principles and GSI is a set of physical best management practices.
