As part of the project, Cedar Point will take several steps to reduce polluted runoff from Town Hall.

Butterfly Garden : A large rain garden, also called a “biorention area,” will be built in natural depression just south of Town Hall. Baker Engineering of Cary is designing the garden to capture and treat runoff from the town’s parking lot.

Got a green thumb? We’ll be asking residents to help plant native plants and trees in the rain garden early next year.

What is a rain garden? :



A rain garden is a shallow, constructed depression that is planted with deep-rooted native plants and grasses. It is designed to receive runoff from hard surfaces such as parking lots, roads and roofs. Rain gardens slow down the flow from these surfaces, hold the water for a short period of time and allow it to naturally infiltrate into the soil. This infiltration reduces the amount of runoff, and the native plants, mulch and soil in a rain garden combine with natural physical, chemical and biological processes to filter out stormwater pollutants. Ultimately, this will decrease water pollution, helping to improve water quality in the White Oak.

Cedar Point Garden : After the plants are established, the garden should be a pretty landscaping amenity and attract butterflies and other insects. A path will take people around the garden and signs will educate them on how the rain garden work and the types of plants growing there.

Town Hall Cisterns : We’ll also install a 3,000-gallon cistern or rain barrel to capture some of the rain water from the Town Hall roof and the planned new multi-purpose building. Water in the cistern will be used for landscaping purposes.

How Can That Help? : Rainwater that falls onto roofs usually flows through yards and across parking lots, washes into the street and eventually flows into a ditch or storm drain. By collecting what would have washed away, we’ll decrease the flow of stormwater and conserving water.
