that is required to establish the vegetation — The vegetation in and around the basin will be matntained at a height of approximately six inches After the infiltration basin is established, it will be inspected once a quarter and within 24 hours after every storm event greater than 10 inches (or 15 inches if in a Coastal County) Records of operation and maintenance will be kept in a known set
