Feasibility of 25 psi blast shelter system for entire population of Providence, R. I. is investigated. Factors analyzed include peak population distribution site availability and ownership accessibility and travel time characteristics of site and surrounding terrain potential flooding, fire, and debris hazard and potential dual purpose shelter applications. Legal financial and construction problems are discussed. Maps and tables define a network of 46 shelters capable of loading to capacity within 30 minutes after alert. Complete coverage of populated areas of the city is afforded by a maximum 34 mile walking radius of shelter. Single purpose shelters cost an estimated 204. per person. Dual purpose shelters such as garages, schools and offices could reduce federal outlay to 147. per person. Cost variation of shelter structure and site sensitive factors with capacity are graphically presented. Additional cost studies cover austere shelter with packaged ventilation kits, cost of upgrading existing below ground structures, and life support systems. An addendum discusses problems of constructing shelters under streets. Author
