The Mile High Flood District proposes to work with Broomfield to develop the final design, acquire right-of-way/easements, and construct drainage and flood control improvements for the Nissen Reservoir Channel from approximately Tennyson Street to just upstream of Lowell Blvd. This area is from immediately upstream of the constructed improvements under Lowell Blvd. to the east side of Walmart near the Cimarron neighborhood. The area between these limits is a narrow channel and wide floodplain impacting businesses and overtopping Perry Street during significant precipitation events. The work includes obtaining all required local, state, and federal permits (including environmental).
