Collective Series J Storm Drain Improvement Project

The Collective Storm Drainage Improvement Project (SDIP) Series J contains three separate projects which vary in size and each bring their unique differences. The work involves various storm drainage improvements including replacement of storm drainage pipes, culvert, masonry drainage structures, water line, sewer line, asphalt pavement, concrete driveways, concrete sidewalk and concrete curb. These improvements will realign storm drainage to reduce structure flooding and address failing infrastructure. Due to the complexity of these projects and their proximity to utility poles/structures/retaining walls, active shoring will be required.
