Here are my two cents. As a principal, owner, we all work together as a team to secure the bottom line, MONEY. Pretty pictures are a selling point to ultimately get paid. I have clients who come to me just for the pretty picture, those are the easy projects, being I am an artist first and LA second.
With that said, there are underlying liability issue involved with graphics…As a Licensed Professional, we protect the public’s Health Safety and Welfare. Therefore if graphics are presented under a seal, then they better be buildable or some trigger happy attorney will have a nice fat fee at your firm’s expense and ultimately putting the qualifier at risk. Landscape Architects as graphic Czars is appropriate, because we can be responsible for the legal realm of graphics, not just a pretty picture.
