Elm & Sibley Street Culvert - 15STR14 

Construction Wards - 7 & 9

Contract Awarded to: L. Keeley Construction


Project Description

Since the passage of Proposition P on August 2, 2016, the Department of Public Works, the Department of Engineering and the Stormwater Task Force have prioritized stormwater projects across the City. The Task Force has recommended 24 projects to be completed including culvert replacements at Elm Street and Sibley Street. The project will replace two deteriorated seven foot diameter culverts beneath Sibley and a sub-standard bridge beneath Elm on Boschert Creek.These existing infrastructures have met the end of their useful life. The project was identified through a comprehensive stormwater analysis. This project includes an expedited culvert construction schedule, and a closure of Elm Street (between 2047 and 2021 Elm Street) for fifty days. When Elm Street is reopened to traffic, construction crews will close Sibley, and begin construction of the second culvert.
