Flooring – Are these boards above the garage structural

flooringgaragejoistsstructural

I started laying out some plywood for storage above my garage, and was wondering id these 2×8's can be removed to make a flatter space. I saw someone refer to them as "catwalks", though I can't find the reference now. There are two of them, and they're basically a 2×4 nailed flat against the joists, and a 2×10 naild perpendicular to that.

There is nothing above except the roof, and the garage is below. Total area is about 30×30'

Cat walk or rat walk is what we called them. We usually laid them flat and would staple the romex. They keep the boards from moving and cracking the Sheetrock, since you are decking the area make sure to do the same with the decking or as you move around it will damage the Sheetrock.
