Before the Performance Period

Create an EPP policy that guides sustainable purchasing for those products purchases that are within the building and site management’s control.

Stormwater reuse costs are minimal for irrigation, moderate for make-up water, and significantly higher for use in indoor plumbing fixtures.

Develop a preventative maintenance plan to evaluate stormwater management facilities regularly and ensure optimal performance.

Stormwater capture may be illegal in certain areas of the country, such as Colorado, where existing downstream water rights take precedence.

Consult with local authorities and ordinances to learn about regulations on stormwater detention features that may influence your management plan.

Convert site area to include infiltration swales, rain gardens, vegetated filter strips and retention ponds.

For urban buildings with small sites, green roofs and rainwater collection and reuse systems are the most likely strategies to bring the project to compliance with this credit.

Install green roofs to reduce the runoff coefficient of the roof area.

Harvest stormwater in tanks and cisterns for reuse.

Substitute porous paving materials in place of conventional asphalt and concrete. This may require installing a new sub-base and is not as simple as repaving.
