Thanks Kristal and Dan, I re-checked the properties on both my basemap and my layer and the Projected Coordinate Systems are both set to NAD 1983 (2011) StatePlane Connecticut FIPS 0600 (US Feet). However the Geographic Coordinate System on the layer is set to NAD 1983 (2011). Could that be it? I checked the units and it says linear unit set to US Survey Feet. could it be the "Projection" of the layer (different than the Projected Coordinate System)? That is set to "Lambert Conformal Conic". I double checked the diameters of a couple of the shapes just to make sure those were in fact the sizes I thought they were and that all seemed to correct.

Hi, I am having trouble calculating the geometry correctly in ArcPro. Here's what I'm doing: In the attribute table, I right click on the column, select calculate geometry, fill in property (Area), and unit (Square feet (US)) and select the coordinate system. The problem is the area calculated is quite a bit bigger than what it should be. For example a circle with a 3 feet diameter calculates as 75. 7 sqFT. I've gone through trying to use geodesc but with such small areas it shouldn't make that much of a difference. My coordinate systems are the same for the basemap and all my data layers. What am I doing wrong? Thank you!
