The roof at Raleigh Union Station with green plants and soil that clean and absorb rain — This green roof at Raleigh Union Station collects rain before it falls to the ground or evaporates into the air. This type of planted roof helps reduce pollution to a stream called Rocky Branch.

Green Stormwater Infrastructure

Eco-friendly development to reduce water pollution

Updated: Apr 26, 2023

Development Projects

Green stormwater infrastructure benefits land development. You can:

Use natural and built landscape features to capture and soak up rainwater.
Reduce water pollution that would otherwise go to storm drains and streams.

Properties and roads with these features have a lower impact on land and they are good for the environment. See more information

What Is Green Stormwater Infrastructure?

City Projects

An engineered, planted area in the median on Sandy Forks Road that collects and cleans stormwater runoff when it rains — Sandy Forks Road has three bioretention basins including one in the median.

There are several City of Raleigh road projects that include bioretention areas. These areas manage the flow of stormwater and remove water pollution coming from a road before it reaches storm drains and streams.

Bioretention Area on Glenwood Avenue Protects Crabtree Creek

Learn about the bioretention area that was installed at the corner of Glenwood Avenue and St. Marys Street in fall 2021. This area is engineered to capture, absorb, and clean stormwater runoff when it rains. The plants, mulch, soil, gravel, and underground pipes work together to slow down the water and filter out pollution before it reaches Crabtree Creek.

Partner Projects

We're partnering with NC State to install green stormwater infrastructure at Biltmore Hills Park. Learn more about this project.

Go Above & Beyond

You can add these features to your property beyond what's required for development. Learn about Raleigh Rainwater Rewards. We'll reimburse you for projects done at your home or business.
