This appendix presents the documentation of the engineering analyses which formed the basis of the designs and costs of wastewater management systems. To a certain extent, the design and cost information was refined in an interative fashion similar to the refinement of the plans themselves. The Design and Cost Appendix presents the development and methodology of the engineering analyses as well as the detailed design and cost of the final plans. The Plan Formulation Appendix documents all significant events and decisions involved in the formulation, evaluation, and selection of wastewater management plans. Other supporting appendices, presenting detailed information on particular elements of the Study include the following: Impact Assessment and Evaluation, Institutional Analysis, and Public Involvement. Also included is the Speciality Appendix which presents detailed analyses of investigations that either overlapped the other appendices or were of particular interest to participants in the Study. These investigations were: the Outlying Communities, river recreation, nonstructural measures, land application, non-point source pollution, and industrial wastewater management. A general profile of the Study Area is contained in the Background Information Appendix.
