*TNT on Wednesday announced its development slate for the 2010-11 television season, including projects from executive producers Jamie Foxx and Don Cheadle. 

Foxx will executive produce and write “Miss Philly,” set in the pristine suburbs and urban war zones of Philadelphia, where the mayor has hired the first African-American police commissioner. “She finds herself handling more than she ever expected,” TNT says. 

Cheadle serves as the executive producer of an as-yet-untitled medical show set in 1971 Los Angeles, where a group of idealistic doctors open an urgent-care clinic in hopes of upholding the values that inspired them to become doctors. 

Other shows in development are from executive producers Mark Gordon, Mark Burnett, Ridley Scott, Tony Scott, Steven Bochco and Dean Devlin.

Jada Pinkett Smith’s “Hawthorne” returns this summer, while “Men of a Certain Age” staring Andre Braugher premieres its second season later this year. Regina King’s “Southland”  will return in 2011.

Also returning this summer: “The Closer,” “Saving Grace,” “Dark Blue,” “Leverage,” “Memphis Beat” and “Rizzoli & Isles.”

Meanwhile, TBS is developing “the Black Family,” an animated series about an interracial family from executive producer/writer Ali LeRoi (“Everybody Hates Chris”), executive producer/artist Todd Goldman and executive producers Keenan Ivory, Marlon and Shawn Wayans along with executive producer Rick Alvarez.
