San Francisco's Chinatown is the biggest and oldest in the country. It's the third most visited tourist destination in the city. It's also the city's most densely populated neighbor- hood. So why are. businesses in Chinatown struggling?

In this week's paper, I outline some of the reasons for why Chinatown's crowded streets and busy shops might be declining. Underneath the surface, Chinatown is falling. And the city, local organizations and businesses are trying to figure out what they can do to turn things around.

While numbers of people visit Chinatown, they don't stay long and they don't spend a lot of money.  And beyond annual festivals,1ike Chinese New Years,  this month's Moon Festival and last month's Sunday Streets - which drew about 15,000 t0 20.000 people – the neighborhood has a hard time attracting locals.

Can you remember the last. time you went to Chinatown ?If you can't, You're not alone. Locals told me that Chinatown doesn't have much to offer them - that the stores are all the same. There are some good eating joints, people said, but they don't know how to find them. Some people even told me that they sometimes go to extreme measures to avoid the neighborhood altogether. But when asked if the-v would like to see Chinatown gone, the answer was always a strong no.

Locals are hopeful that things will get better and traffic will increase when the Central Subway is complete. But chat's not for another five years. at least. And if' new shops or restaurants don't make their way into Chinatown. the same problem of attracting locals will exist.

Not that Chinatown's going to die. The dragon still has some fire in its belly. And many people are rooting for positive change. The question is, how does Chinatown change without losing the very importance of what makes it unique?
