Richmond City Council is guaranteed to have at least two new members sworn in next year, with a potential for additional newcomers depending on the outcome of the five contested races that voters will decide on Election Day.

Of the nine members, only two from South Side are guaranteed re-election, Councilman Michael J. Jones of the 9th District and Councilwoman Kristen N. Larson of the neighboring 4th District. Both are unopposed in seeking their second, four-year terms.

Highlighting the council races are the contests to fill open seats in the 2nd and 3rd districts, both of which include large swaths of North Side.

In the 2nd District, urban and environmental planner Katherine L. Jordan and health care information technology specialist Tavarris J. Spinks are battling it out to replace first-term Councilwoman Kim B. Gray, who chose to run for mayor instead of re-election.

In the 3rd District, barber Willie E. Hilliard, drone company owner Ann-Frances Lambert and community investment strategist Elaine T. Summerfield are facing off in a quest to replace 16-year veteran Councilman Chris A. Hilbert, the current council vice president, who decided to step down rather than seek a new term.

Meanwhile, four incumbents are battling to keep their seats. In the 1st District, Councilman Andreas D. Addison is trying to overtake two challengers to secure a second term. His challengers are businessman Michael R. “Mike” Dickinson and public relations company partner and co-founder Michael C. “Mike” Gray.

In the 5th District, Councilwoman Stephanie A. Lynch, who won a special election last year to replace Parker C. Agelasto, also is battling two challengers in a bid to win her first four-year term. Her challengers are journalist and former School Board member Mamie L. Taylor and business development specialist Jer’mykeal D. McCoy.

In the 6th District, 17-year veteran Councilwoman Ellen F. Robertson is seeking another four-year term, but must overcome a challenge from community organizer Allan-Charles R. Chipman.

In the 7th District, 11-year council veteran and current Council President Cynthia I. Newbille is facing a challenge from museum educator Joseph S.H. Rogers.

In the 8th District, 18-year veteran Councilwoman Reva M. Trammell is trying to win a new term and prevent either of her challengers, mortgage consultant Regie D. Ford and analyst Amy C. Wentz, from inflicting a second defeat. Ms. Trammell, who was first elected to the council in 1998, spent years on the sidelines after losing in 2002 to Jacqueline M. Jackson, who held the seat for four years before Ms. Trammell defeated her in 2006.
