As a north Brookside resident (my house is literally on the map above - I'm west of Peoria/south of 31st), this looks great to me.
I walk from my house to Brookside "proper" all the time... I've been hoping for a while that the west side of Peoria north of 34th would get a little bit more developed, and I think this would certainly potentially benefit that.
Well, I confess, I have just gone down a rabbit hole on this development and related development from Kaiser and TGP, the possible Crow Creek trail, and the like. Spent waaayyy too much time thing morning, but pretty cool stuff.
When you say North of 34th on the West side, what area do you mean? The area South of Crow Creek is already commercial (but yes, could be improved upon), and the area North of the Creek on the SW corner of Peoria and 32 st is owned by Kaiser. (Who I assume is holding it as part of the proposed trail.) North of that is all existing residential.
After looking at what Kaiser owns, it could make sense to acquire the land immediately across Peoria and South of the line that would be the extended 32st, and make some kind of entry into Brookside, with the requisite parks, etc. Any non- residential development North of the 32 st street line seems (IMHO) intrusive on the current residential nature of the area.
