J.Del, probably the Number One Issue holding Newark back is its reputation outside of Newark. According to suburbanites, you would get robbed and murdered the second you get off the Interstate onto Broad Street. Most of them either have not stepped foot in Newark since the 1960's and 70's, or they have only ever returned for an occasional event at the Prudential Center in which they drove to the most expensive parking lot right next to the arena and the drove away the second that the event ended. Up until VERY recently, every single news article about Newark started with "In a City ravaged by Race Riots" and not always mentioning that they were in 1968, regardless of what the article was actually about. If anything, the high ranking on that Amazon HQ2 search significantly changed the reputation of the city. But the damage to the city's reputation has been done.
The stubborn reality is that cities are reliant on suburban shoppers to add to the economy. They CANNOT just rely on their residents and the Downtown office workers. In order to draw the shoppers back, you need to both create better inviting shopping streets (Ferry Street's facade program and the streetscape improvements have made it a tourism destination in addition to efforts of the community), and you have to improve the city's reputation. Outside of the COVID days, events and new developments serve as a good way to draw people back to "rediscover" the city. However the focus on stolen cars being set on fire or people shooting up Heroin in the middle of the street is not doing anything to help. If anything, it contributes to the constant response from social media users, which is to "Drive a fleet of bulldozers through Newark and leave it as Scorched Earth".
If the shopping streets can be revived, they are more likely to have small businesses that hire locally, and to be owned by Newarkers. That puts the maximum amount of money back into Newarkers' pockets and into the city's schools and services. The new warehouses also help to hire a lot of locals. Both groups of businesses are going to dodge any place where they perceive their businesses are at risk. I am NOT saying to censor the crime and decay reports and whatnot. There are better ways to deal with them. Report the graffiti and the decaying infrastructure on the city's app called Newark Connect or This Site
https://seeclickfix.com/web_portal/KQP3H8fCJTzzBnMjmVKUsQo6/report/category There is everything from garbage complaints to sidewalk and pothole reports on there and the city responds to most of them. They monitor it from 8-4, Monday to Friday. Report the crimes to the police, anonymously if needed. The police non-emergency number is 973-733-6000. Just don't overdo it with being a narc. They might already be working on the specific area of drug dealing but they need to build up a case to hold the gang leaders for more than a few hours.
