A longtime employee of the Douglas County appraiser’s office has agreed to lead the department until a permanent replacement is named.

Steven Miles, an appraisal manager who has worked there for 18 years, will be the interim leader after appraiser Marion Johnson retires from the department today, County Administrator Craig Weinaug said.

The county is searching for a permanent replacement for Johnson, who served as appraiser for 18 years. County commissioners on Monday will decide how to narrow the field of 10 candidates for the new position.

Weinaug said administrators will recommend that commissioners interview two internal and two external candidates. He declined to identify any of the candidates.
