The party is scheduled to be held in the Oregon District, a popular nightlife area where the Aug. 4 mass shooting unfolded.
"This event will honor the lives lost and to reclaim the community’s favorite places to shop, dine and enjoy time with family and friends," the Facebook event page said.
Titled the "Gem City Shine," the event is strictly for Dayton residents, according to a registration page.
“You will not be able to redeem tickets, even if you receive a code, unless you are a legal resident of Dayton, OH area,” the page read.
Guests will receive a commemorative T-shirt in exchange for a $20 minimum donation that will go toward the tragedy fund at the Dayton Foundation, the page stated.
Dayton Mayor Nan Whaley tweeted about the party Wednesday, saying she was "so excited" to announce the event.
