Maintenance Policy

The operational characteristics of all culverts, storm drains and similar appurtenances should be preserved as near as practical to the originally constructed or subsequently modified conditions. This will assure normal cross-roadway drainage. Such appurtenances include:
  • non-bridge classified culverts
  • catch basins and drop inlets
  • dips
  • storm sewers
  • irrigation siphons
  • drainage pumping stations
  • stock passes.
