STORMWATER IMPROVEMENT PROJECTS
BOULDER OUTFALL -
This intersection has an undersized storm sewer system that results in frequent flooding from moderate storm events. The project will consist of replacing the existing undersized storm sewer system with a larger capacity storm system in W. Abriendo Avenue from Lincoln Street to the storm system outfall at the Arkansas River along Boulder Avenue. Improvements will help mitigate frequent flooding events in this area and will include approximately 1,650 LF of 60” storm sewer, installation of new manholes, inlets, laterals, water quality and open channel improvements.
Illinois Avenue Storm System Upgrade
This area has experienced significant flooding over the years due to an undersized Stormwater system. This is one of the most frequently complained about areas that routinely requires the time and resources of the Stormwater Maintenance Crew. The upgrade project will consist of replacing the entire existing Stormwater system along Illinois Ave. from Poplar St. to Lakeshore Dr. Approximately 1,100 LF of mainline pipeline will be increased in size (10" to 24") with additional inlets if needed. Also, all pavement, curb and gutter that is removed will be replaced.
An existing pump station that serves to remove storm runoff that collects at a low point near the intersection of I-25 and 29th St. has failed on several occasions and poses a public safety concern. Improvements will include constructing a new pump station in an area away from the low point location to improve capacity, public safety, and maintenance issues. The existing wet well will be converted into an oil/grit separator to help enhance water quality.
