2. #1 Land Use: commercial, urban, or parking lot. Water Quality Problem: storm water runoff carries motor oil, gas, and litter into nearby streams BMP: plant islands of shrubs and trees to reduce runoff and allow some infiltration to recharge groundwater. #1

3. Land Use: agriculture or farming Water Quality Problem: streambank and sediment are falling into stream due to loss of streamside shrubs and trees. BMP: plant native species of shrubs and trees to hold soil in place and stop bank erosion. #2

4. #3 Land Use: commercial or residential construction Water Quality Problem: storm water runoff carries sediment into nearby streams BMP: provide erosion control, such as silt fences, to prevent runoff carrying sediment from reaching the stream.

5. #4 Land Use: agriculture or grazing (pigs). Water Quality Problem: livestock grazing trample streambanks causing erosion, and animal wastes add nutrients and bacteria to streams. BMP: limit or prevent livestock grazing along streams; allow native shrubs and trees to grow along streambanks to prevent erosion; provide a water tank for livestock to drink from located away from the stream.
