I was responsible for creating the environments below.  I modeled all of the architecture, terrain, props, and foliage.  I modeled high and low versions and baked out normal and ambient occlusion maps where applicable.  I UV mapped everything and created all textures and their materials.  I set up the lighting, volumetrics, and post effects.  These levels run on both a PS3 and X360 at 30fps and fit within console memory limitations.
