What documentation is necessary to assess if a new shopping center parking lot can be built in a floodway?

To determine if a new shopping center parking lot can be built in a floodway, both a floodway encroachment analysis and site plans are necessary. A floodway encroachment analysis is critical because it evaluates the potential impacts of the proposed development on the floodway and its capacity to carry floodwaters. This analysis helps determine if the project would adversely affect flood levels or the natural flow of water.

Site plans are equally important as they provide a visual representation of the proposed development, detailing how the new parking lot will fit within the existing site and its relationship to surrounding properties and floodplain boundaries. By examining both the floodway encroachment analysis and the site plans, regulatory authorities can make informed decisions regarding the feasibility of the project, ensuring compliance with floodplain management standards and minimizing the risk of flood damage.

While the floodplain development permit application might be required as part of the overall permitting process, it does not serve as a standalone tool for assessing project impacts, unlike the specific analyses and site documentation. Thus, the combination of the floodway encroachment analysis and site plans provides a comprehensive approach necessary for evaluating the implications of building in a floodway.
