He held that position between 2010 and 2012 before the city hired Steve Hasson for the post. Hasson resigned last month.
LaPine Mayor Ken Mullenex says Allen will once again commute.
"Yes, Rick still lives in Madras. He'll be commuting. He'll work probably less than 30 hours a week. He'll be working on high priority items as there are state budget deadlines coming up. He won't serve more than a year and we'll put a new city manager in place."
The city plans to use the League of Oregon Cities again to hopefully find a new permanent city manager in the next year.
