Phase 4

We’re installing a storm BRIGHTON R sewer system with a E WHAT V I R five-year capacity to E T T A L service Five Points, P H T U O S Whittier, City Park West and Cheeseman Park. Our goal is to improve drainage during storm events and address areas where significant MARTIN LUTHER KING JR. BLVD. flooding could occur.

The new box culverts we will be installing are 10 foot wide by 8 feet deep — that means almost 43 times as EXISTING SYSTEM TWO 6'-TALL NEW 5-YEAR SYSTEM CONSTRUCTION much water can flow WORKERS through this new and improved system.

To safely perform this extremely complicated construction, we will HOW need to close this intersection for 33RD ST. approximately 3 months.
