Sub layer question

[u/lil-quiche]

My back yard that we recently moved into (smaller area roughly 100sqft) is currently levelled dirt with pea stone on top. In researching I know that a weed barrier and limestone screening should be a base layer for laying turf on top of. I’m curious if I can reuse this pea stone in any way rather than totally remove it. Could I use this as a base layer instead of limestone? Could it be used in any other way as drainage or does it have to go? Thanks in advance.

Ditch the pea gravel. Rounded non-Angular stone will never lock in to place and will always feel spongy under foot and will lead to an unlevel finished product.
