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 Timing
We know that timing of the project is also an issue. SPU explored the possibility of constructing the project before the new South Park Bridge opens in 2014. But it is not possible to design and construct the project responsibly before the bridge opening. Rushing the project can lead to cost overruns and additional delays.
At the same time, 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.
Next Steps
The project is entering the design phase with the goal of starting construction in 2014.
