That's fair and understand why you'd clarify but the streetcar is a unique service that doesn't exist elsewhere in the metro, streets/sewers/etc do. It's a free fare horizontal elevator ride to many amenities/entertainment, huge benefit to developers and long term investment of the property. Pretty good chance the value of projects will be higher in the long run along streetcar vs. similar project not (even after factoring higher property tax). In that context, the streetcar is the incentive in that it should boost value of their investment in the long term at a higher % than say the value of the 39th/State Line project going in.
Piling on more incentives because the presence of streetcar is increasing land value is an awful precedent to set. Let the market play out in context to what has been laid down. But developers also shouldn't be buying up what locals consider historical worthy and then hold it hostage for incentives. This developer really does have good intentions and have shown that from the start. But at this point they are also milking what they can given they now have the support from historical orgs.
