San Diego City Councilwoman Marti Emerald is officially in the race to represent the City's new, 9th Council District.
She filed her papers Tuesday with the City Clerk's office.
Her first challenger for the June 5 primary is City Heights resident Katherine Eaton. Eaton also filed her paperwork to run.
District 9 was created by a voter approved measure that switched San Diego to a strong-mayor form of government. Elections for the new district will likely be in December.
A redistricting commission used 2010 Census data to outline its boundaries from the College Area, through part of City Heights and down to Southcrest.
Emerald lives in the College Area near San Diego State University, according to KPBS.
"My staff and I have been representing many of the neighborhoods in this new district since I assumed office and we have a great relationship with them," Emerald told KPBS. "I look forward to continuing our partnership with these communities and the other neighborhoods in our new district."
