Dallas Police Chief Renee Hall is reorganizing the Dallas Police Department.

On Thursday the chief released an outline of her plan, which is "expected to bolster department crime fighting resources citywide, increase command-level presence in the field and improve the quality of police response to citizens," the department said in a press release.

The plan comes after a "top to bottom assessment" of the department, and "includes the appointment of her command staff. Only the police chief can select officers to the highest ranks of assistant and deputy chief and major."

The chief announced that she will be reducing the number of assistant and deputy chief positions at DPD, "while establishing higher expectations and responsibilities for majors, lieutenants and sergeants."

“The new structure will deploy and maximize resources to make our city safer and more responsive to the needs of the community," Dallas City Manager T.C. Broadnax said. “I appreciate Chief Hall’s thoughtful and thorough process to move the department forward.”

Starting Dec. 13, the department will go from having nine assistant chief positions and 13 deputy chief positions, to having only three assistant chief positions and seven deputy chiefs.

Among those demoted include Deputy Chief Malik Al'Aziz and Assistant Chief Gary Tittle, who were both finalists for the chief of police job before Hall was hired. They are now listed as majors within the department.

Here's a list of the rank changes:

There will still be 15 majors, and the seven patrol divisions will be put into four geographic sectors: central, south, east, and west, the department said. Each will have its own deputy chief and two majors -- one working during the day and the other working at night.

“Criminals don’t conform to our geographical enforcement boundaries, and we need a flexible structure to put officers where and when they are needed," Chief Hall said. "That includes supervisors and command staff officers. I want the citizens of Dallas to see a much more engaged police force."
