Lance, in order for parking to ever be approved for a street, the street must be wide enough for a car to fit, as well as maintain a minimum width for travel. The width is based on the amount of traffic for the road as well (calculated from a number of places including the number of residencies that will be accessing the road on a daily basis). You are right about one thing, it will slow down traffic since anytime you reduce the width of travel, people have the tendancy to naturally slow down. Personally, I don't care for the indents. I believe it encourages poor parking habits since people seem to think they have the additional 2 feet on top of what they would have if the indent weren't there. Not sure why that is, but just an observation! Either way, if you contact KL, they can direct you to the design engineer who can verify if it is safe or not (I believe it is Stantec but I'm not completely sure). I personally wouldn't accept their word for it since they do have a way of distorting the facts in their favor. The design engineer on the other hand has a professional obligation to be completely honest with you.
