Exactly, you would think Mcdonalds wouldn't mind loosing a few feet wide swath of land for a walking path. It doesn't have to be big most sidewalks are only about four feet wide. It would be used by thousands walking throughout the day that might just decide to grab some to go food to snack on in the park or after getting back from the park.
For ADA compliance, the sidewalk would need to be 6' wide. The sidewalks along the east side of Harbor Blvd appear to be 8' wide and this path would likely need to be at least that wide for capacity; for a landscaped buffer to make it a welcoming environment, they would need even more room, likely 3-4' on each side
Looking at the McDonald's site, it doesn't look like they can add an 8' pedestrian path without removing the entire line of parking on the south side. That means losing 30% of the parking capacity (26 of 87 spaces) at one of the busiest McDonald's in the country. No matter how many incidental customers that sidewalk may bring, that's going to be a very tough sell by Disney
Similarly, Disney may allow the adjacent hotels to connect a "back door" to their new walkway, but it would require them to lose revenue-generating rooms and/or parking to make that connection. Just because someone lets you make a connection to their property doesn't mean it's a palatable option for you
As it currently stands, that segment of Harbor Blvd is one of the most walkable streets in southern California (which may say more about the general state of things than about Harbor Blvd specifically). It has a lot of elements that urban planners refer to as "complete streets" and is a welcoming environment, despite the heavy usage of the road and the excessive number of driveway entrances interrupting the sidewalks.
As a transportation engineer, Disney's proposal to force all Harbor Blvd pedestrians to the new security site seems misguided at best. Any guest staying on Harbor Blvd (no matter how far north or south) will be forced to go east to go west to the parks, adding about a quarter mile to their trip. Good pedestrian design seeks to make the most direct route possible, which this certainly does not do
I know that Anaheim has different priorities than more dense urban areas that deal with a lot of pedestrians, but I'm really surprised they're even giving this serious consideration. I work for pedestrian-friendly jurisdictions and I'd get laughed out of the room if I suggested something like this; even as a temporary detour this would be a tough sell. There is more than enough room at the existing Harbor transit plaza for them to build an adequate security checkpoint for pedestrian arrivals alongside the proposed bridge/ramp, so I'm not sure why this proposal has made it this far.
I think it also opens them up pretty easily to an ADA lawsuit since it adds so much distance to the most direct route. I don't think that requiring 2 buses/shuttles to cover that distance would fly in court, especially since boarding and alighting is significantly more complicated for people with mobility impairments. ADA is vague about this specific type of scenario, but it typically encourages the accessible route to be the most direct route whenever possible
I'm also curious about the fate of the existing traffic signal; it appears that it will remain for the ADA and cast shuttles to make the left turns. If the signal remains, it will be very difficult to discourage pedestrians from crossing there (even if they remove all sidewalks along the west side of the street), which could make the intersection even more unsafe than it is now if there's no marked crosswalk. Short of removing the signal and adding a median with a fence in that area, people are going to keep crossing there
I don't fault Disney for this proposal at all. They want to serve their guests, the vast majority of whom will arrive at the parking garage; pedestrians aren't a major concern for them. I'm just surprised that the City is going along with it. It just doesn't seem to be good urban design, for a variety of reasons
