The stormwater management area shows examples of stormwater management and erosion and sediment control practices in use within MD and are displayed along a walkway for easy access and viewing.
According to the Maryland Department of the Environment:
Controlling nonpoint source pollution is the responsibility of Maryland's State and local governments. To help citizens, engineers, inspectors, students and business leaders understand nonpoint pollution, federal, State, and local governments joined together to create an outdoor classroom.
Other practices included at the area: Sediment trap, berms and diversion dikes, horizontal and vertical checkdams, silt fence, pipe slope drain, infiltration trenches, porous pavement, sand filter, stone check dam, water quality inlet for pretreatment. There is a extended detention wet basin, shallow marshes and bioretention for view.
Now about the Earthcache. At the starting coordinates, you should see 3 signs along the pathway to the west. There is one to the right across the bridge. You will need to visit these signs and a 4th sign answer the questions below. Once at the sign across the bridge, go downhill to Shallow Marsh and snap a photo of you and your gps with the water in the background. There is a picture posted of the water in the lake.
1. What are 2 infiltration practices on display here?
2. What are some nonpoint source pollutants in our region? (name 3).
3. Which watershed is Fairland Regional Park located in and where does it drain into?
4. You need to find your way to the Extended detention wet basin and get a photo of you, your gps and the water in the background. A little walk down the paved path to the south and you will be there.
5. How many inches of rain can the extended detention basin hold during a 24 hour period?
