3.8 Noise Mitigation

(0.93 points)

Rationale

Practices that mitigate noise reduce exposure to environmental noise pollution, supporting improved sleep. 

Strategy Requirements

Mitigate noise pollution within open spaces within the project boundary by:

1. identifying all significant noise sources within 1/2 mile or 800 meters of the project boundary. Significant noise sources include:
   1. interstates, highways, and principal arterial roads with 6 or more travel lanes
   2. heavy industrial/agricultural use
   3. heavy rail and at-grade/elevated rail transit
   4. airport facilities
2. implementing a minimum of 2 of the following practices to alleviate excess noise:
   1. siting open spaces and outdoor amenities away from significant noise sources
   2. siting buildings to buffer open space from noise sources 
   3. installing physical barriers to redirect noise to unpopulated areas
   4. using dense landscaping and natural material strategically placed at noise sources and outdoor amenities to absorb excess noise
   5. grading and mounding land to redirect and absorb noise
   6. restricting access for heavy vehicles in residential areas

Not applicable

Confirm that there are no significant noise sources within 1/2 a mile or 800 meters of the project boundary
