  • Direct roof runoff into cisterns or rain barrels for use.
  • Direct roof runoff onto vegetated areas. 
  • Direct runoff from sidewalks, walkways, and/or patios onto vegetated areas. 
  • Direct runoff from driveways/uncovered parking lots onto vegetated areas. 
  • Construct sidewalks, walkways, and/or patios with permeable surfaces.
