This document was developed at the request of the city of Watertown, Minnesota, to present some conceptual solutions to flood proofing problems of structures in the citys floodplain. This report is intended to provide some general concepts of flood proofing based on a tour of the problem structures. State law and the city floodplain ordinance require that detailed plans and specifications be prepared by a licensed engineer or architect prior to issuance of a building permit for construction of flood proofing features. This report does not satisfy the requirement for detailed plans and specifications of flood proofing designs. Before the concepts presented in this report can be implemented, they must be developed into detailed plans and specifications after more detailed inspections of the problem structure are conducted.
