Sewage Backup Prevention Project

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 pipe 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 2015.

Next Steps

The project is entering the design phase with the goal of starting construction in 2015. 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.
