The XY tolerance and XY resolution revert to default values while creating a new feature class in a geodatabase with any projected coordinate system set to US Feet.

Solución alternativa

1. Create a new feature class in any geodatabase and select the projected coordinate system with measurement units as US Feet.
2. After creating the new feature class, open the Project tool and select the new feature class in the 'Input Dataset or Feature Class' parameter and in environment setting assign a custom XY tolerance and XY resolution. The workaround successfully assigns the custom XY tolerance and resolution to the feature class.
