Specifications include, but are not limited to: The project will have two phases. In Phase 1, the Consultant will determine the impacts of the 1,000-year storm over the entire District service area within Milwaukee County. Inputs will include the Milwaukee County 2020 LiDAR data and an appropriate source for rainfall data. Atlas 14 has estimates for the 1,000-year storm, but the Consultant may advocate for another determination. The Consultant will analyze the flood mapping and identify key locations for which additional analysis may be warranted. Technical stakeholders will be brought into the process at this point to help with selection of areas (both location and size) to study in Phase 2. The consultant will facilitate stakeholder gatherings to identify where further analysis would be helpful to define the flood risks in the county. Focus areas will be chosen based on criteria agreed upon by the stakeholders and may include items such as flooding extents, threat to District or municipality assets, threat to public safety, transportation obstructions, socioeconomic conditions, or other stakeholder goals. In Phase 2, the Consultant will move from the countywide analysis to a (sub)watershed-scale analysis. The identified areas will be analyzed separately to refine the flood analysis to determine the magnitude of the risks to the stakeholder’s criteria. The subwatershed analyses will include determination of potential next steps and the champion(s) who may move that work forward. Categories of Work: Planning, Computer Hydraulic Modeling, Climate Change Impacts, Large Storm Modeling.
