Abstract:

The National ASCE Task Committee on: 'COSTS-BENEFITS OF VARIOUS DESIGN FREQUENCIES FOR URBAN DRAINAGE SYSTEMS AND FLOOD CONTROL' recommends that public officials check into the costs versus benefits of establishing frequencies of protection for various urban drainage systems and flood control. Inadequate drainage protection, property costs, clean-up costs, direct and indirect costs of travel delays, legal fees, and other cost items should be considered. Total costs should be computed for construction costs and total damage costs for each possible drainage design frequency.
