Source Control Measure Fact SheetStorm Drain Inlet Markings and SignagePurposeThis fact sheet provides details about permanent “Nodumping-drains to creek/river” messages at storm draininlets and “No dumping” signs at public access points tochannels and creeks on the development project site, whereapplicable. Storm drain markings are intended to help stopillegal dumping by alerting people that the drain leadsdirectly to a water body and dumping is prohibited. Signs ataccess points to creeks and channels serve as reminders thatdumping there is illegal.ApplicabilityAs indicated in Table 4-1, permanent storm drain inletmarkings are required on all new drain inlets (also knownas catch basins) installed in development/redevelopment projects. Signs are also required at publicaccess points to any creeks or drainage channels within oradjacent to the site.Design RequirementsTo protect water quality, follow the requirements shown in Table SD-1 to create consistent “no dumping”messages at storm drain inlets and public access points at creeks and channels.Table SD-1. Design Requirements for Storm Drain Inlet Markings and SignageDesign FeatureLocationMessage Layoutand ContentMethod ofApplicationCriteriaIdentify all storm drain inlets on the improvement plans and indicate they must be marked withappropriate storm drain messages.Locate the message on each inlet as described in the next section.Follow the message layout, content, and other specifications provided by the local permittingagency. Each agency may have its own design. See figure SD-1 for example detail.For signs posted at access points to waterways, consult the local permitting agency for theirrequired/preferred message and style.Alternatively, obtain approval from the local jurisdiction for a different layout/message that clearlyprohibits dumping using words or graphical icons.Consider the use of bilingual messages where appropriate based on local population.Permanently apply the message at storm drain inlets by stamping it in concrete, affixing as a tileor cast-iron plate, or using an alternative approach approved by the local jurisdiction.For area drain markers, make sure any inset tiles or plates are flush with the surface of the inlet toavoid a tripping hazard.Consider permanently affix signs at access points to creeks and channels.Operation and MaintenanceThe legibility of storm drain inlet messages and signs must be maintained to ensure effective pollutionprevention over time.Stormwater Quality Design Manual for the Sacramento and South Placer RegionsMay 2007SD-1
