If your question is something like 'where can I expect puddling and flooding you will not achieve this with a flow accumulation surface. Flow accumulation is returning a new grid where each value is the number of cells that flow into that cell. Your urban area has a vast network of storm water facilities that are not accounted for meaning your flow ...

This is a large radius, so this will be computationnally expensive. That being said, focal stat is the good tools if you have only 1 and 2 values: make the sum of the cells with focal stat, then "percentage of cells == 1" is equal to 100*(2*(number of cells in the radius)-(focal stat result))/(number of cells in the radius)

I created a simple model in ArcMap ModelBuilder that adds the shapefile name as a new field in the shapefile. I assumed that your shapefiles are all in the same folder (Test) and not in sub-folders. If they are also in sub-folders, make sure to set "recursive" in the iterator tool. For the add field tool: make sure the field type is set to TEXT, ...
