What is the reason for the deep cut in the center of the W site. It has water in it now. Is it for a sump pump to keep water out of the building after it is built?

And why was the Four Seasons allowed to build sooo close to the street and into the existing sidewalk. I thought sidewalks could not be obstructed. This building, being so close to the street, does not have enough space left along Cesar Chaves to plant any trees. This building appears to not follow Austins' Great Streets guidelines; and for a high end condo building this does not make sense. Any info?
