For what it’s worth I advocate for a numbering schema that means something (ie DCB_xxx, SMH_xxx) and here in Westwood the numbering itself relates to the location in town they are…..sewer mini-systems or catchments, which really helps when you’re trying to find it/them. I’ve worked with the other way and those numbers are illogical and get really big and then just try to label your map! Having a layer that shows where the ‘catchments’ are helps too.
My two cents before I retire J……………………

I'm a big fan of unique IDs that don't mean anything. If you have 1,000 catchbasins, call the next one 1001, regardless of where it is. If it's in a GIS, the number doesn't need to tell you where it is.
Your boss will hate this idea, so of course you'll have to come up with some kind of watershed-based system.

Subject: Stormwater Feature NumberingHello all,
Here in Bangor we’ve had our stormwater infrastructure in GIS for some time, but currently use a grid-based numbering system which is not particularly useful for anyone. We’re considering a switch, as we have not done a significant amount of asset management on stormwater yet and the current system is quite confusing for our field crews. Looking ahead, toward more asset management work, we’d like to have a better system in place.
Our sanitary sewer system is numbered like a branching tree, with a two letter prefix denoting subsection and a three number pipe id number, which are divided into branches by 100s / 10s as necessary. So for instance AB123. This system works well for us, but unfortunately can’t easily be replicated for our stormwater system because it is discontiguous in nature.
Our current grid-based system is more-or-less arbitrary, but includes the complication of using a grid which is otherwise unreferenced elsewhere in the city. This is creating many headaches and conflicts among staff.
Would you be willing to share what your community is using for stormwater numbering and what the pros and cons have been in using this numbering system?
Thank you very much,Sean
