“It just seems that the Bronx’s moment has arrived,” she said.

Morris Park is well positioned to capitalize on interest in the borough. Residents not only have subway and express bus service, but expect to have their own Metro-North station on the New Haven line in the next several years. Last month, a ferry route opened between Clason Point Park, about 20 minutes away, and Manhattan.

The neighborhood has also been long rated among the safest in New York. According to city data that is updated weekly, crime in the 49th precinct, which includes Morris Park, has declined 8.5 percent in the last two years and 27.6 percent in the last eight. In the year ending on July 31, the incident rate was 11.5 per 1,000 residents, a lower figure than in the 26th precinct of Manhattan, which includes Morningside Heights, or the 17th precinct, which includes Murray Hill.

“A lot of people are trying to get in,” said John DeFonzo, the manager of the Morris Park Avenue outpost of Patsy’s Pizzeria, who lives in the attached brick house on Rhinelander Avenue that his grandmother bought 70 years ago when she arrived from Italy. “In the last year and a half, when I see new faces, nine out of 10 times they’re new people living in the neighborhood.”

But Albert D’Angelo, who headed the Morris Park Community Association before becoming chair of Bronx Community Board 11 in July, sees a fine line between opportunity and opportunism. Some outside investors, he noted, are turning multifamily homes into illegal boardinghouses, crowding the community, exacerbating traffic problems and straining resources.

Mom-and-pop stores prevail because a shortage of parking spots has discouraged larger businesses from opening on the commercial stretches of Morris Park Avenue and Williamsbridge Road, Mr. D’Angelo added. Congestion is one reason the community association is fighting a city plan to narrow vehicle lanes and introduce bicycle lanes on Morris Park Avenue.

He predicted that the new Metro-North station will help solidify Morris Park’s reputation as a desirable middle-class district. “There are very, very few neighborhoods in the city where you can grow up, go to school, go to college and hang out with friends that can be your friends for 40 to 50 years,” he said.
