Immediately after the infiltration basin is established, the vegetation will be watered twice weekly if needed until the plants become established (commonly six weeks). No portion of the infiltration basin will be fertilized after the initial fertilization that is required to establish the vegetation. The vegetation in and around the basin will be maintained at a height of approximately six inches. After the infiltration basin is established, it shall be inspected once a quarter and within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal County).
