Understanding the Key Features of Low Impact Development

Introduction:

Thank you for taking the time to read this article on the key features of Low Impact Development (LID). LID is an innovative approach to land development and stormwater management that aims to mimic natural drainage processes. It focuses on reducing the impact of urbanization on the environment by integrating sustainable design techniques.

1. Minimizing Impervious Surfaces:

One of the main principles of LID is to minimize impervious surfaces. Impervious surfaces, such as concrete and asphalt, prevent rainwater from infiltrating into the ground, leading to increased stormwater runoff. LID promotes the use of permeable materials and designs that allow rainfall to infiltrate into the soil, reducing runoff and replenishing groundwater.

2. Preserving Natural Features:

LID encourages the preservation of natural features on development sites, such as trees, wetlands, and natural drainage channels. By maintaining these features, LID helps retain the natural capacity of the land to absorb and filter stormwater runoff, reducing the burden on traditional stormwater infrastructure.

3. Managing Stormwater at its Source:

Traditional stormwater management systems collect and convey stormwater through a network of pipes and channels. In contrast, LID emphasizes managing stormwater at its source. This approach involves using a combination of techniques, including bioretention areas (rain gardens), permeable pavements, green roofs, and rainwater harvesting systems. These techniques help capture, treat, and reuse stormwater on-site, reducing the volume and pollutant load of runoff entering streams and rivers.

4. Protecting Water Quality:

LID plays a crucial role in protecting water quality by reducing the amount of pollutants that enter our waterways. Through the use of natural filtration processes and engineered treatment systems, LID helps remove contaminants, such as sediments, nutrients, and heavy metals, from stormwater runoff. This improves the overall health of ecosystems and enhances water quality for human and wildlife populations.

5. Enhancing Urban Green Space:

By incorporating green infrastructure elements, LID contributes to the creation of urban green spaces. Green roofs, rain gardens, and vegetated swales not only provide stormwater management benefits but also enhance the aesthetic appeal of urban areas. These green spaces offer recreational opportunities, improve air quality, reduce the urban heat island effect, and promote biodiversity.

By implementing techniques that reduce, infiltrate, and capture stormwater runoff at its origin, LID helps reduce the volume and velocity of water entering our waterways.

Permeable Pavement: Permeable pavement is an effective LID technique that allows rainfall to infiltrate through the pavement surface and into the underlying soil. This type of pavement is designed to promote infiltration, reducing stormwater runoff and promoting groundwater recharge.

Rain Gardens: Rain gardens are shallow depressions planted with native vegetation that collect and absorb stormwater runoff from rooftops, driveways, and other impervious surfaces. They utilize natural biological processes to filter pollutants and recharge groundwater.

Bioretention Cells: Bioretention cells are engineered depressions filled with engineered soils and vegetation. They are designed to capture and treat stormwater runoff by filtering out pollutants and allowing water to slowly infiltrate into the ground.

Green Roofs: Green roofs are roofs covered with vegetation and a growing medium. They provide multiple benefits, including absorbing rainfall, reducing stormwater runoff, improving air quality, and reducing the urban heat island effect.

Conservation Easements: Conservation easements are legal agreements that permanently protect environmentally sensitive areas from development. They can be an important tool in promoting LID by preserving open spaces, forests, wetlands, and other natural features that help manage stormwater runoff.

LID techniques offer numerous environmental and economic benefits. By mimicking natural systems, LID can help reduce flooding, improve water quality, enhance biodiversity, conserve water resources, and create attractive green spaces. Additionally, LID can reduce the need for costly infrastructure such as larger stormwater pipes and treatment plants.

In conclusion, understanding the key features of Low Impact Development is crucial for anyone interested in sustainable land development practices. By implementing LID techniques like permeable pavement, rain gardens, bioretention cells, and green roofs, we can effectively manage stormwater runoff and create a more resilient and environmentally friendly built environment.
