1 New Hampshire DOT Glenn Roberts, Chief of Research Development and Implementation of Interactive Stormwater Outreach Model and MaterialsNew Hampshire DOTGlenn Roberts, Chief of Research
2 PurposeFulfill National Pollutant Discharge Elimination System (NPDES) Phase II regulations for Small MS4sDevelop & Implement a Public Education and Outreach ComponentPresent and promote best management practices (BMPs) resulting from experience, research in water quality issues, and innovations in stormwater managementMS4 stands for municipal separate storm sewer systems, but the term also includes State department of transportations, universities, local sewer districts, hospitals, military bases and prisons. It’s not only for systems of underground pipes – it includes roads with drainage systems, ditches, channels or other stormwater components.Six minimum control measures required. First is Public Education and Outreach.
3 1st Generation Interactive Table Constructed with minimal materials & expense3 layers of plywood, painted to depict Concord, NHGrooves cut through layers allow “contaminants” to travel to surface waters
4 2nd Generation Stormwater Table Improved detail and reliefWorking culverts, swales, ditches, silt fences, grass, etc.
5 RainmakersAll of the stormwater tables require Rainmakers. Contaminants are placed on the roadways and landscape to depict real world pollutants from non point type sources identified in other outreach components.Salt and sand from roadsIncreased nutrient loadings from fertilizers and detergentsGas and other petroleum productsPet waste, trash, and construction sediment.The rain comes and washes them into ditches, culverts and streams, eventually making their way to potential drinking water sources.
8 Silt Fence DemoErosion control issues and best management practices are also discussed. This slide shows a student applying “construction sediment”, which is effectively blocked by a model silt fence. When the fence is removed or breached, the sediment escapes into the wetlands and streams.
9 Stormwater Outreach Trailer The stormwater outreach trailer provides transportation for the stormwater models and provides an enclosed space for slide shows and other presentations. The trailer is covered on four sides with a mural created by a local technical school art club which depicts various non point sources of pollution.
10 Stormwater Outreach Team (SWOT) This is the SWOT team. They are a group of dedicated, passionate, champions from the NHDOT Bureau of Environment that truly believe in and love what they do, and they’ve been a joy to work with.

12 3rd Generation Stormwater Table In this slide, members of the SWOT team show interested onlookers the difference between water that is filtered by detention basins or grass swales, and water that could emerge directly from a drainage pipe into rivers, lakes or streams.
13 Sampling of Events Berlin River Day (Gen. Public) Lebanon Watershed (4th Gr)NHDOT District Safety DaysLGC Career Day (High Sch.)Plow Rally (Municipalities)Town of Gorham 4th of July (Families)Canterbury School (4th & 5th Gr)Winnicut River Watershed (Families)NHDOT - Earth DayNH Fish & Game – Discover Wild NH Day (Families)Exeter Adult Ed Center (Adult Ed. Students)Manchester Public WorksMountain of Demonstrations (Municipalities)NHDOT Lunch & LearnMany moreMost of the slides I’ve shown include kids, but as you can see from this sampling of events, more than half of the time the SWOT addresses adults or families. Not that we need to apologize for involving the kids. After all, what better time to start to influence future adults’ attitudes toward these issues.Event names, dates, contacts, audience, group size, hours, miles traveled, MS4 town status, and other information are maintained in a permanent log.
14 Future Plans Animated presentation(s) Advertisements for local media outletsSolar power to reduce/replace use of generatorAdditional outreach materials (e.g. coloring books, shirts, mugs)Smart boardOne idea that’s been discussed but not yet developed is the idea of a smart board, or touch screen, which enables participants to test their knowledge through interactive exercises.
15 Thank YouThrough a unique partnership of the NHDOT’s Bureau of Environment and the Research program, an effective outreach program has been developed from the ground up, at minimal cost, and is now helping to spread the word on achieving higher water quality through the effective management of stormwater runoff.
