In this swale we book ended the low spot with culverts and used sheet drains to lead into the culverts from both approaches. We considered installing a drain and culvert along the flat area, but decided that we lacked enough slope to easily move water through the flat area. We chose to completely harden the area instead using native rock, then geotextile and finally capped with 3/4 minus gravel.
