Coinciding with the start of hurricane season, the Fairfax, Va.-based Public Entity Risk Institute (PERI) has released the 2006 Risk Management Yearbook, a collection of articles about levee maintenance, hazard mitigation and disaster recovery. Written for risk managers, emergency managers, disaster professionals and policymakers, the book reveals lessons learned from last year's storms — including Hurricane Katrina — and examines emerging trends and challenges facing local governments, small businesses and non-profit organizations.
