SWM Facility Signage Detail

1. These signs need to be added to the plans for any SWM facility that does not have a dedicated outlet structure, i.e. infiltration trench, bioswale, etc.
1. A bioswale will have a “Mow Line” sign at the upstream and downstream ends as well as the “BMP” sign (with assigned BMP #) needs to get installed on the same signpost as the upstream “Mow Line” sign.
2. For any facility that does not have a dedicated outlet structure, the “BMP” sign (with assigned BMP #) needs to get installed next to the facility.
