Grading of hillslopes to create pads for home construction has contributed to the frequency of landslides in southern California. This is because grading can alter the natural slope and stability of the hillside, making it more prone to failure. It can also disrupt the drainage patterns, leading to the accumulation of water and increased pore pressure, which can trigger landslides.
