Implement stormwater management practices

Rationale: Implementing practices to manage the quality and quantity of stormwater runoff prevents pollution, erosion, and flooding, mitigating risk of injury, infection and illness from contaminated drinking water; stormwater management also prevents biodiversity loss, which supports exposure to diverse microbiota, contributing to a strengthened immune system.

Requirements

Demonstrate compliance with the below:

Stormwater Management Plan (Full Credit):

To achieve full credit, demonstrate compliance with all of the following requirements:

1. Provide a minimum of one qualifying stormwater infrastructure element.

Qualifying stormwater infrastructure elements may include but are not limited to the following: 

– retention ponds 

– permeable pavement 

– green roofs 

– blue roofs 

– rain gardens 

– bioswales 

– cisterns.

2. Ensure that the stormwater infrastructure manages all of the following, as applicable: 
   • controls stormwater runoff 
   • treats stormwater runoff from the site prior to entering local water sources 
   • treats stormwater separately from sewer water 
   • protect areas where chemicals and hazardous waste are stored during high precipitation events 
   • prevents oil, gas, and grease from entering sewer outflow and stormwater runoff.
