What this page shows

The S-333 MAINTENANCE DREDGING AND LOW SILL WEIRS permit, filed to Phillips Heavy, is one of 91 storm water construction permits in Miami, and it sits among 8 NPDES permits in the Conservation Area 3A subwatershed. Of those 91 Miami storm water construction permits, 4.4% were issued earlier than this one, and 0.0% carry a violation on file, so this permit has none of the records that would count as a violation.
