North 21st & Ogden Storm Sewer Project
Project Start Date: June 1st, 2020
Location: North 21st Street and Ogden Avenue, just East of McDonald’s
The Area of Ogden Avenue North of 21st Street is located in a combined sewer district known as district 2. Projects constructed to separate storm infrastructure in combined sewer districts have been proven effective at reducing water-in-basement issues throughout the City. The intention of the proposed project is to diminish flooding risk for the area along Ogden Avenue North of 21st Street. Modeling of the combined sewer in this area indicates susceptibility to surcharging (overloading of the sewer beyond its design capacity) during wet weather events. Residents connected to these combined sewer mains have reported basement backups in the past during wet weather events.
The project consists of constructing 331 lineal feet of 12-inch Reinforced Concrete Pipe (RCP) storm sewer, installing new storm inlets and structures, removal of 30 lineal feet of Vitrified Clay Pipe (VCP) combined sewer, removal of combined storm inlets, installing sanitary manholes in alley entrances, placement of curb and gutter for one-half block along Ogden Avenue, resurfacing of bituminous roadway along Banks Avenue and alleyways, and resurfacing of concrete pavement at 21st Street intersection.
Week of June 1st: Removal of Ogden Avenue existing roadway & combined sewer, installation of sanitary structures.
Week of June 8th: Removal of 21st Street pavement and installation of new storm sewer,
Week of June 15th: Reconstructing 21st Street, Ogden Avenue, and alley roadways.
