Sample Data Stormwater Data Management Solution

[RickHendrickson1]

Hello,

We are migrating some stormwater data into the Stormwater Data Management Solution. I have questions about how to use all the various feature classes and would love to see some sample data. For example, say there is a trash insert inside of a catch basin. Are you supposed to put the BMP poly around the entire thing, put a BMP inlet where the water goes in, and the BMP point where the trash filter is? So if you know of a sample dataset please let me know.

Thanks!
Rick

@RickHendrickson1 From my perspective, the answer to this question really depends on your organizations needs.  Unfortunately I don't have sample data that would help gain further insight into your specific question.  I do hope that someone in the Community can share more specific / user insight, but I will do my best to give you at least one perspective.
My initial gut reaction to your question (without knowing your organizational needs) for this use case above, would be to consider adding a new BMP Point, snapped to the Catch Basin.  This point would represent the trash insert to provide you a location of the BMP.  Now your trash insert could be tracked seperate from the catch basin itself and inspection and maintainence history of that trash insert is seperate from the any catch basin specific inspection and maintenance tasks. In this scenario I would not add a BMP Inlet or a BMP poly around it.  Happy to chat more if you would like.

Thank you for the reply. Yes that makes sense and was what I was leaning towards. We will likely use the BMP poly for something like a grassy swale and the BMP inlet where there might be a curb opening into the swale. I do have a question in that case though, are you still supposed to add a BMP point within the grassy swale?  Thanks!

Adding the point in the grassy swale situation is another odd one.  If, for example, you use BMP Points to generate an inspection for all BMPs, then adding to both the point and the polygon would be the best approach in my opinion (since not all BMPs will have polygons). Of course you can certainly have only BMPs in one or the other, you would just have potentially two seperate BMP Inspection tables.

If you are editing the layer in ArcGIS Pro you could create a template to add the polygon and add a BMP Point too at the same time, which might help reduce errors if forgetting to add both - just a thought.

Long story short, using them in tandem is the approach if you were to use the Utility Network. You would want the point for network connectivity in the network, but the polygon for a better representation of the asset itself.
