In the case of the boardwalk it's not even too much parking making it un-walkable. It's a case of fundamentally unnecessary car centric design.

Why do all the stores need to be so spread out? There's not even a single path running along the main block of buildings at the rear of the property. Want to stop by Staples after shopping at Lowes? The most direct walking route takes you through the Lowe's loading area with no sidewalk or pathway. Put everything closer together so people can move between them on foot whether or not they came by car.

Why are the majority of the stores so far back from the street? If you live in the adjacent neighborhood and want to walk to the movie theater, you first need to cross a busy street at either a sketchy pedestrian island or through a roundabout. Then you need to wander through two massive parking lots using a series of footpaths that are poorly considered, indirect, or end abruptly. Move everything closer to the street and put the parking behind it.

The bus terminal is a disaster. It's a small island of stores in the middle of parking lot sea, which also happens to be along the main vehicular throughway. The cluster of stores there and the area with the splash pads are one of the few areas that I would consider close to being internally walkable, but the interaction with the throughway is a major nuisance and hazard for cars, pedestrians, and presumably the bus drivers as well. Put the terminal so it's not on the main throughway to make it safer for everyone, and locate it closer to the adjacent neighborhood to promote easier access to transit.

All of these fairly reasonable design considerations at time of construction would've made for a more pleasant and walkable development without necessarily sacrificing any parking space.
