Yes, there are several exterior features for rainwater management. Here are a few examples:
1. Permeable Pavement: Permeable pavement is a type of pavement that allows rainwater to pass through its surface and infiltrate into the ground below. It helps to replenish groundwater and reduces stormwater runoff. Common types of permeable pavement include pervious concrete, porous asphalt, and permeable interlocking pavers.
2. Rain Barrels: Rain barrels are water storage containers that capture and store rainwater from rooftops. They usually have a spigot and overflow valve for easy access to the collected water. Rain barrels can be connected to downspouts to capture rainwater efficiently and can be used for various purposes like watering plants, washing cars, or even non-potable uses.
3. Green Roofs: Green roofs are vegetative layers installed on the roof surfaces of buildings. They help in rainwater management by absorbing and retaining rainwater, reducing stormwater runoff. Green roofs also provide additional insulation, improve air quality, and create green spaces in urban areas.
4. Rain Gardens: Rain gardens are shallow, landscaped depressions designed to collect and absorb rainwater from roofs, driveways, and other impervious surfaces. They are planted with native vegetation that helps to filter and absorb the runoff. Rain gardens not only reduce stormwater runoff but also enhance the aesthetic value of the outdoor space.
5. Grassy Swales and Bioswales: Grassy swales and bioswales are engineered landscape features designed for managing stormwater runoff. They are shallow channels or depressions planted with grasses or other vegetation that slow down the flow of water, filter out pollutants, and promote infiltration.
These are just a few examples of the exterior features used for rainwater management. There are many more techniques and technologies available depending on the specific needs and characteristics of the location.
