Amanda, Sorry for the delay in responding to your comment. Attached are revised plan sheets 2.3 & 2.4 which show the stormwater outfalls you noted. On the revised sheets these outfalls flow into a floodplain depression & are no longer a ditched feature. This is similar to what we constructed on Holly Branch at the Mayland Community College site. This revision does not change proposed impacts to streams & wetlands. Let me know if you have questions or additional comments.

Just looking through the PCN and noticed the plan sheet with the stormwater outfalls (attached). Any way to incorporate having the wetlands/flood plain out there be able to treat/dissipate this versus what is being proposed as a ditch draining directly to the creek. I'm assuming the current conditions is just that so seems like a good opportunity to correct this if possible. Thanks for the consideration!
