Question: How do I fix an edge-of-field bioreactors tool error? I believe “sheds_poly” corresponds to the polygon feature class of the drainage areas of each bioreactor site, which is an internal calculation of the tool. I tried saving the output Bioreactor shapefile to a new file geodatabase (.gdb) to see if perhaps there was not enough memory in the current file geodatabase, but the same error resulted. Only 1 field boundary was identified in this particular watershed as requiring tile drainage. Any thoughts?

Question: What is the unit of measurement for the NRCSWidth in the Riparian Function Tool Outputs?

Question: I am working to hydro-condition a watershed that has a heavily developed area. Sometimes water goes into storm ponds so I leave that impeded flow alone, but sometimes water flows into underground systems where I can’t find the output. In that situation, how should I handle incorrect impeded flow?

Question: I am getting strange outputs from the “Stream Reach & Catchments” step. Why are additional segments being added to the stream reach?

Question: I am working on the Precision Conservation Practice Siting Tools and have run my files through the Depression Identification Tool. Now, I am trying to go through each polygon to see which are true or artificial depressions and having trouble. How do I know which should be deleted?

Question: My DEM is currently in the NAD 83 UTM zone 16 projection which is the correct zone for our area and matches the projection of the data downloaded from the ACPF website. It says the vertical accuracy is 6.24 cm and the horizontal accuracy is 0.6 m. Should I resample my raster to have 7cm z-factor and 1-meter cell size?

Question: I downloaded LiDAR data for my county, and it is a DTM file. Can I use a DTM instead of DEM?

Question: Can you help clarify my confusion about the Z factor? I am going through the Pit Fill/Hole Punch process, and I put in .18 since the training manual says 18cm and the raster is in meters. Is that correct?

Question: How can I get the ACPF to work with ArcGIS Desktop 10.4? I am having issues with the DEM Fill process and was hoping the reason for the error was because I am using Desktop 10.4.1.

Question: Can a field boundary polygon be a multi-part polygon? Would it make sense to explode the polygon and assign it a new number? What would the processes of assigning it new land use information based on the new geometry look like?

Question: My boundary and buffer polygons keep getting deleted. In the hydro-conditioning process I am running the D8 Processing Tool, running the PD Flow Network, running the Depression Depth Tool, adding cutlines feature class, creating cutlines and then running the Manual Cutter Tool. Afterwards, when I run the PD Flow Network or the Depression Depth Tool after making edits my boundary and buffer lines get deleted. Why is this happening?
