Thanks,
@Rover .
I have lived here for almost eight years. During that time, most folks didn't have a clue who owned the development, what was a part of it, what was planned, and what was "coming soon!" until DivCo added transparency to the mix.
Regarding height ... there are a few folks in CX who have mentioned height negatively during my tenure, but honestly: had DivCo seen a benefit in building skyward, they would have and most residents would have merely said, "wow". That's the general reaction I have heard regarding Lot I's monolithic core.
Remember: several of these structures were linked to tenants much sooner than expected (Lots G, H, and U), despite detractors suggesting DivCo would build a bunch of empty structures and then leave. And the developer is building what is in demand among (mostly, stereotypically) upper middle class urban professionals and their employers: contemporary open work and lab space, non chain dining, green space, and semi-luxe residential. I have reviewed documents back to 2004: regardless of what could have been built here, my study revealed no one (formally) ever pushing height beyond 350', IIRC.
Beyond that, I have read waves of criticism regarding the park, and even the site's total footprint and its corresponding general lack of density. Judging from how many folks use it year round, and even now with COVID-19 and snow, I think there's a sour grapes mentality at work. Surveys have shown that one thing folks absolutely adore about Northpoint, and now CX, is the park (and, more recently, how DivCo is building sub park spaces around the new tenants). Residents, their guests, and plenty of folks from nearby communities (Museum Way, Glassworks, AVA, Zinc, One Canal, One First, Point 262, etc) use the facilities. Absent COVID it can actually get rather packed.
I've never been a NIMBY, and I do have a predilection toward supporting height: but with such positive support among end users for what's here, and (most) criticism relegated to internet forums, I posit that it's working well. And that's the point.
