The term the real estate industry uses for Sacramento County’s Department of Environmental Review and Assessment isn’t flattering. They call it “a black hole.” County leaders are aiming to break free of the reputation by revamping the way it handles development. A just-released sweeping audit of the county’s development services offers 99 recommendations. They range from building a multimillion-dollar service center to regular staff evaluations. The county is also considering creating a new agency to oversee all functions associated with development. The would resolve another big issue the auditors identified: lack of communication between departments. The Board of Supervisors is expected to review the audit at its meeting this month.
