This $60M residence captures the Bel Air view using concrete to create a robust and yet elegant finish. For this project -and in large scale developments where impervious areas have a higher-than-average magnitude- we coordinated with city officials to determine the most cost effective way to keep runoff volumes at the lowest so that structures end up being optimal for the catchment area. A slope reparation plan was provided to avoid erosion from the irrigation area and the LID structures were placed along the repaired extent.
