I hope Greater Syracuse truly
does embrace the notion of downtown living as being a viable way to restore your city's overall liveability. My specialty is accounting, not urban planning, so you can take my advice with a grain of salt if you so choose, but here are some of my opinions.
I firmly believe that if you increase your downtown's population, you'll also improve the bottom lines of existing downtown businesses and make it more feasible for new entrepreneurs to open up shops and restaurants to latch onto this new consumer market. In general most downtowns that are undergoing residential renaissances are targeting the upper-middle-class exclusively, but I'm hopeful that Syracuse will take a different path for its downtown---even offering rent-subsidized apartments to permit lower-income families to enjoy the convenience of living downtown if possible. I can speak from experience that Center City Philadelphia is one of the most vibrant residential downtowns in the nation, with an estimated 100,000 people living in its central business district, but with average smaller-sized condo prices rivaling the prices of most typical suburban Syracuse single-family detached dwellings on large lots, that has become an option reserved exclusively for generally more affluent people to partake in.
As the downtown booms with hundreds of new residents from all walks of life, you'll see Syracuse transformed from its current 9-5 doldrums to a 24/7 cosmopolitan city. Crime downtown will largely dissipate, as the increased foot traffic spawned by all of the new residents makes it more unattractive for would-be thieves to strike. Soon the image of Downtown Syracuse will change for the better, and it will become noted as an "up-and-coming" place to live. At this point you'll also see some younger families wanting in on the action but also wanting a yard. This will herald the start of gentrification and rebirth in neighborhoods adjacent to downtown. Homes will be rehabilitated, neighborhood watches and associations will be reignited, and entire long-neglected parts of the city near to downtown will become habitable again, driving the criminal elements further out from the city's core.
By and large anyone who doesn't think the notion of supporting downtown housing is a sound one truly isn't thinking with a lucid mind. In the short-run folks might think "Bah. Who'd want to live in Downtown Syracuse?" In the long-run (10+ years) this "seed" planted now will reap a tremendously rewarding harvest later. I'm likewise excited about the downtown living options coming to both Scranton and Wilkes-Barre, and I hope other cities like Binghamton and Elmira latch onto this trend as well. With fuel prices hovering around $3.25/gallon and only expected to continue to spike, the "American Dream" will transition away from a large SUV and a far-flung cul-de-sac to a fuel-efficient family sedan (Camry hybrids perhaps) and neighborhoods closer to urbanized areas.
Best of luck, Syracuse!
