Dolezal recently came under fire after her parents said the 37-year-old activist falsely portrayed herself as black for years.
In a Facebook post, Dolezal says chapter vice president, Naima Quarles-Burnley, will take over her role.
"Please know I will never stop fighting for human rights and will do everything in my power to help and assist, whether it means stepping up or stepping down, because this is not about me. It's about justice. This is not me quitting; this is a continuum," she said in her Facebook post. You can read the Facebook post in full below.
Dear Executive Committee and NAACP Members, It is a true honor to serve in the racial and social justice movement here...Posted by Spokane NAACP on Monday, June 15, 2015
Dolezal was elected president of the local NAACP chapter about six months ago.
Ruthanne Dolezal, Rachel Dolezal's mother, said the family's ancestry is Czech, Swedish and German, with a trace of Native American heritage. She produced a copy of her daughter's Montana birth certificate listing herself and Larry Dolezal as Rachel's parents.
The city of Spokane is investigating whether Dolezal lied about her ethnicity when she applied to be on the police board. Police on Friday said they were suspending investigations into racial-harassment complaints filed by Dolezal, including one from earlier this year in which she said she received hate mail at her office.
