The Engineering Division of the City of Helena seeks the services of an engineering firm to provide services necessary to complete a Preliminary Engineering Report (PER), meeting WASACT formatting requirements, of the existing stormwater system serving the downtown area (Last Chance Gulch Basin) and provide recommendations for increasing the system’s conveyance capacity/storage capabilities. At the present time the City of Helena wishes to evaluate the existing stormwater system serving the downtown area and consider alternative design options to reduce the potential for flooding during larger rain events. The project will entail completion of an in-depth study of the existing stormwater network located within the downtown area (Last Chance Gulch Basin) along with recommendations for potential upgrades in line with current stormwater best management practices.
