Hello Kam members, I wondered if any of the counties have addressed culverts and if so I wanted to get some discussion on that to see thoughts regarding it. This was brought up by a department head as something we should possibly do. Any thoughts or comments would be helpful. Thank you!

Riley County has a road grid where every Section is divided into 100 squares. Each N-S grid line is #'d as: F.0, F.1, F.2, F.3 etc up to F.9, the next section would start with G.0, G.1 etc. The E-W grid lines are #'s as: 1.0, 1.1, 1.2 etc up to 1.9, then the next section would start 2.0, 2.1 etc These grids are used to assign locations to the middle of a road segment and to culvert locations.

Thanks Sherie for your comment, so I take it you just have a separate GIS layer just for this purpose?, and this is just for "in-house" use as well?, I was questioning whether or not to create a separate layer and would that be best or to put them into the 911 address layer and code them somehow within that database to identify them as culverts, My concerns were how this would effect 911 operations, or would it?, would it clutter the map with addresses? But the good things I thought would come out of it were that if accidents happened at culverts and an address was posted at each location they would be found easily and 911 would see it on their mapping, however at the same time wouldn't they anyhow if the caller was on their cell phone?... In the end I think it would be more of a use for Road and Bridge and keeping track of maintenance so possibly it would be better to just create a separate layer. These are the things I've been trying to sort out in my thoughts regarding this idea, so thank you again for your input I appreciate it.

My preference is to keep them as a separate feature class outside 911 data. There are standard culvert attributes and once you create the layer they may want to use it for maintenance. With regard to finding and naming, I side on using the map to find them rather than depend on a coded grid system for naming (of course we have fairly decent cell coverage here). We are just now implementing an ArcGIS Online map for our townships to collect their culverts (as public data). Below are the attributes we are using:

Pipe Material, PipeLength_ft, Opening Height_inches, OpeningDiameter_inches, Township, EndTreatment_IN, End_Treatment_OUT, Description, InstallDate, Maintenance Date, Road_Name, Comments, Pipe Condition, Maintenance Condition. Also have attachments enabled and editor tracking turned on.

We use drop down list values wherever possible.

Lee thanks for your input, the more I think about it the more I think it would be best to keep them out of the 911 addressing data and just create a separate layer for them. I do like the ideas you shared. As far as an "identifer" or "address" for these culverts can you give me an example of how you plan to address yours and the method behind that? would you give them an address based off the road centerlines or some unique method of identifying them? Thank you - Tina

We have a separate layer for the culverts with a field for that grid # that is assigned to it. We also have a field in road centerlines with the grid # for the center of each road segment. Using the grid for road centerlines in this way is handy. If a road is 10 miles long, but there is a problem on 1 mile of it, Road & Bridge can pinpoint the location with that grid ID #.

I would just create an ID field, but not an address. The actual location on the map is how you tell them apart. You could create a field with the "road name - ID" number if you want a little clue about where it is just from the ID. As far as communicating with staff, we have IPads as well as create map books that have the surrounding building footprints, water lines, addresses/parcel lines so that the staff can figure out which one they are looking for by using the surrounding area. Hope this helps.

In Pottawatomie county we also rely on a coordinate system to narrow down the locations of our culverts. Additionally, our culvert names are prefixed with the township abbreviation they're located in. Culverts are their own separate feature class (nothing to do with 911 addressing) and we store data about the physical characteristics of each culvert. Attached is a page from our "Bridge Book" that has a sampling of the data from Belvue township. (This page was exported from the map attribute table and manipulated in MS Access to create a report).
