There is no detail on design. <br />' e What happens when they fill up? How do <br /> 9 they drain out? What happens if we have two <br />' 10 100-year storms back to back or within a week of <br /> 11 each other and there is water in those containment <br />' 12 d <br />i <br />th <br />ll <br />ti <br />d <br />?
