East 16th Avenue Storm Interceptor

16th Avenue Storm Interceptor project web banner


The East 16th Avenue Storm Interceptor project area is located in Montclair Basin (Basin 4500-03) of the City and County of Denver Storm Drainage Master Plan. There are existing storm sewers in East 16th Avenue and Batavia Place which are currently undersized to convey the stormwater resulting in frequent and significant flooding of the neighborhood area.  The goal of this project is to work with hydrology developed by the Outfall Systems Plan (OSP) team to size, design, and construct a new storm main line to safely transport the flows from existing systems in Colfax Avenue and East 16th Avenue towards City Park, while picking up the local flows along the way.

Project Details

This project will improve safety and reduce flood risks in the South Park Hill neighborhood by building a new stormwater system which will include installing a larger stormwater pipe to provide additional capacity to carry and drain stormwater in the area.

The existing storm sewers in E. 16th Ave. and Batavia Pl. are currently undersized to adequately convey stormwater levels, resulting in frequent and significant flooding in the South Park Hill neighborhood. The construction includes installing a new stormwater pipe beneath Colorado Boulevard which will connect to the current the stormwater system at City Park Golf Course.
 
In addition to the storm pipe construction, work includes roadway reconfiguration and traffic signal changes at the intersection of E. 17th Ave. and Colorado Blvd., as well as safer crossings for pedestrians and cyclists.
 
Work begins at Jackson Street and E. 17th Avenue, continues east along E. 17th Avenue Parkway, crosses Colorado Blvd and turns south onto Albion Street for approximately 100 feet.
