KB Home Flood Due to Shoddy Building Practices. Undermines the home's foundation. Mold is in the house from this cause. The City did not have any third party double check KB Home's grading plan. The waterfall cascades over the retaining wall, which is over 4' ft tall. It needed a permit, it was built without a legal permit. Violates State water codes and the 1979 FTC Consent Order.
