I picture the persona of my user to be someone who doesn’t necessarily have a lot of monetary stake in the ongoing developments in and around my area of Brooklyn. Those that do tend to be older and less in-touch with technology-they could operate a website but an app might be a challenge, let alone getting them to engage.
They’re involved in either public policy or local politics or are residents (most likely recent residents) that have a piqued interest in the recent developments in the area. They’re certainly upstarts, familiar with sites that compare rankings of locations on a map-that is yelp, Zillow, etc.
They come across this site via social media most certainly, perhaps having read about it on a local news website or blog. They can include reviews/ratings of the building developers and see more info once selecting a certain one.
Ideally this would be all on one screen, either a map or a list-all of the additional info and ratings should be pop-ups.
