The retirement system made an up to $100 million real assets commitment last week.
The new manager was selected for the $60 million mandate following finalist interviews with four total firms this summer.
The plan also delegated investment authority to its executive director.
The retirement plan received three submissions to its RFP issued earlier this year.
The plans currently work with general investment consultant Callan.
The county is seeking the services on behalf of its $9.9 million 457(b) and $414,000 401(a) plan.
The plan added a pair of private equity commitments and another to a credit opportunities fund.
The deferred compensation plan replaced its domestic small-cap growth and international large-cap value equity managers last month.
The search is required due to state procurement law requiring an RFP every seven years.
The hires followed closed session deliberations.
