Chapter Content
Limit paved areas and use permeable paving solutions for walkways, drives, and plazas.
Design shared parking and reduce unnecessary hardscape.
Detailed Explanation
This chunk focuses on the importance of reducing impervious surfaces in landscaping and site planning. Impervious surfaces, like concrete and asphalt, do not allow water to seep into the ground, which can lead to increased runoff and potential flooding. By using permeable materials, rainwater can filter through the surface and replenish groundwater, enhancing sustainability.
Examples & Analogies
Think of a sponge: when you pour water on it, it absorbs the liquid, which helps prevent a mess. Similarly, permeable paving acts like a sponge, soaking up rainwater instead of letting it run off into storm drains.
Low Impact Development (LID) Practices

Chapter Content
Rain Gardens and Bioswales: Shallow depressions planted with native vegetation filter and absorb stormwater.
Green Roofs: Vegetated roof surfaces retain rainfall and release it slowly.
Infiltration Trenches/Percolation Pits: Direct runoff underground, recharging groundwater.
Detailed Explanation
Low Impact Development techniques aim to manage stormwater in a way that mimics natural hydrology. Rain gardens and bioswales use natural landscaping to capture and filter rainwater, while green roofs provide a living surface that absorbs rainfall and reduces runoff. Infiltration trenches help channel runoff underground, recharging the groundwater table.
Examples & Analogies
Imagine a sponge (like a rain garden) placed in a dish that collects water. Instead of overflowing, it soaks it up, preventing spills. Similarly, green roofs act like sponges that absorb water, reducing the risk of flooding during a heavy rain.

Chapter Content
Install rainwater harvesting systems to collect runoff for landscape irrigation or non-potable uses.
Use cisterns or storage tanks sized to local rainfall patterns.
Detailed Explanation
This chunk discusses the significance of capturing and reusing stormwater, which can alleviate pressure on municipal water systems. Rainwater harvesting systems collect rainwater from roofs and other surfaces, storing it for irrigation or non-drinking purposes, which helps conserve potable water resources.
Examples & Analogies
Think of it like collecting extra water in a container after washing a car. Instead of letting the water go down the drain, you save it for watering your plants later. This is similar to how rainwater harvesting worksβstoring rainwater for later use.
Stormwater Treatment

Chapter Content
Implement oil/grit separators or vegetated filter strips to remove contaminants before water leaves the site.
Detailed Explanation
Effective stormwater treatment is crucial for maintaining water quality. Oil/grit separators are designed to capture pollutants like oil and dirt from runoff before the water enters the drainage systems. Vegetated filter strips, on the other hand, use plant roots to absorb nutrients and filter out contaminants, ensuring cleaner water as it heads into local waterways.
Examples & Analogies
Imagine washing your bike in the driveway; if dirty water runs down the street, it can pollute local rivers. Now, picture using a special mat with grass (the vegetated filter) to catch the dirty water. This way, contaminants are filtered out before reaching the nearby drainage system, keeping rivers clean.
Natural Waterways and Buffers
Chapter 5 of 5

Chapter Content
Maintain or restore riparian buffers along streams or ponds to filter pollutants and provide habitat.
Detailed Explanation
Natural waterways and their accompanying riparian buffers are essential for maintaining healthy ecosystems. These buffers consist of vegetation that help filter out contaminants from runoff before it enters streams or ponds. They also provide critical habitat for wildlife and help stabilize bank erosion.
Examples & Analogies
Think of these riparian buffers like a friendly fence around a garden. Just as a fence keeps out pests and protects the garden, these buffers filter out harmful substances from water and protect the aquatic environment, making it a healthier place for plants and animals to thrive.
