There are three compliance paths available to meet the requirements of this path. Tenants can locate in a building with one of the following attributes.
To document this credit provide site plans that indicate the areas of shading, highly reflective surfaces, open-grid or pervious-hardscape areas and parking under cover.
Refer to NC SSc7.1for detailed requirements and documentation guidance. Note, however, that the requirement for this option through LEED-CI is to meet the credit requirements for 30% of the non-building-area instead of the 50% required for NC projects.
Try to locate the project in a building that has a stormwater management system meeting LEED requirements. Constructed wetlands, filtering systems, bioswales, retention basins, or other systems that remove suspended solids from stormwater, will contribute to meeting credit requirements.
Refer to the stormwater management plan or consult with your building’s civil engineer to learn the site’s imperviousness. If it is less than 50% impervious, the stormwater management plan must equalize the pre- and post-development peak discharge rates and quantities from the one-year, 24-hour, design storm. If your site has more than 50% impervious cover, the plan must reduce the volume of stormwater runoff by 25% from the 1½-year, 24-hour, design storm.
Request a copy of the stormwater management plan, if there is one, listing the best management practices implemented for onsite treatment or onsite storage of stormwater.
