Per as-builts received, the as-built pipe slope was observed to be 0.16%. While this is below the minimum required slope listed in the drainage certification checklist, the pipe as constructed still has the capacity to convey 4.20 CFS. As observed from the EPA/SWMM model output (see next page, from the As-Built Design Report for the Remington Street Storm Sewer Outfall Improvement Project, prepared by Anderson Consulting Engineers on December 7, 2020), the expected flows through this pipe are 6.3, 4.6, and 2.4 CFS in the 100,10, and 2-YR storm events respectively. Thus, in the as-built condition, the 18" RCP pipe should be able to convey the full 2-YR event, 91% of the 10-YR event and 66% of the 100-YR event. It was also observed that this inlet is expected to be significantly flooded/surcharged in the 100-YR event so the slope of the newly constructed pipe should have little to no impact on the ROW stormwater system.
