Integration of Ecological Considerations in Stream Design

Emma Blythe, EI, Project Engineer, Timmons Group

Whitney Thomas, PE, CFM, ENV SP, Senior Project Manager, Timmons Group


An overview of the need, methods, and implications of including ecological planning along with physical restoration design; this presentation will discuss ecological restoration – a design approach to encourage the reestablishment of  biodiversity at many hierarchical levels of life. As an ever-evolving science, this presentation will review academic research results suggesting possible avenues of planning and design improvement that may be beneficial in encouraging biodiversity return post-construction.  A discussion of how these considerations and other future impacts to the environment are or can be included as part of stream design projects will be discussed.
