Ryan,
I’m going to copy the other Ryan on this as I think he would be better suited to comment on that, but just to clarify this would just be a mini ditch to carry water off the side of the
trail, correct? Where present, are these intended to stay earthen or will they be concrete, and is there any sort of velocity reducer where they are or is that only intended for the
longer v-ditch areas?

Subject: EXTERNAL: Water Diverter Location
Hi Ryan,
While walking the trail and marking the locations for several water diverters on the Canyon Loop Trail today, we found an area of the trail that had some erosion after the recent rain.
The team that was on-site felt a water diverter would be best suited in the attached location. The 6ft diverter would basically run across the trail and flow toward the orange flag
in the photo. Our question for you is……do you foresee an issue with water being diverted towards an area heavily populated by the prickly pear cactus? We tend to believe this area
is well vegetated and the water would dissipate over a wide area naturally, but curious for your opinion.
Thank You,
Ryan
