14th and Concord Sewer Improvement Project

Project Update - April 2015

In late April, geotechnical investigations and utility location will be conducted on 14th Avenue South as part of preliminary work on the project. While the main construction effort on the project is anticipated for early 2016, this work is needed to determine current conditions around the sewer alignment. View details about location, schedule and impacts.

Project Background

The 14th and Concord Sewer Improvement Project will install a new pipe to increase capacity to convery stormwater and sewage. The pipe will run under 14th Avenue South, between South Concord and South Donovan streets, and west under South Donovan Street to 12th Avenue South (see map). Added conveyance capacity will relieve chronic sewage backups in homes and businesses and reduce chronic flooding in the area of 14th Avenue South and South Concord Street.

Please see the project fact sheet for more information, including what to expect during construction in early 2016 and next steps.

Options Considered

SPU examined various options to avoid further disruption along 14th Avenue South, including a route through several private properties. However, the private property route would impact eleven private properties, potentially cost significantly more, and forever restrict those homeowners from building on their property easements.

Selected Alternative

For these reasons, SPU determined that the best option is to install a new, larger pipe to collect stormwater and sewage under 14th Avenue South, between South Concord and South Donovan, and west under Donovan to 12th Avenue South (see map).

Project Schedule

We know that timing of the project is also an issue. SPU examined an expedited schedule to construct in 2014. The decision to not pursue the expedited schedule was due to high risks identified that are typical for unplanned activities. Construction is anticipated for early 2016.

Next Steps

The project is 90% designed with the goal of starting construction in early 2016. SPU is committed to exploring construction methods that will minimize impacts to South Park businesses and residents, and we will be contacting all those potentially impacted to make sure they have the opportunity to share their concerns and inform our actions. Stay tuned for more information from the project team and in the meantime, please join the project listserv to receive updates.
