Understand Patio Base Problem

What happens here

The video begins by illustrating an existing issue: a "hump" of soil mounded up against the last wooden step of a deck, which was apparently done by whoever installed the deck. This uneven grading creates an obstacle and an unsuitable base for a patio. The goal is to remove this excess soil and establish a flat, level surface, and to replace the problematic soil-to-wood step transition with a more permanent and aesthetically pleasing ledger stone step.

Goal: Identify the current landscaping issue and the planned solution for the patio base.
