Oak Street Assessment District – 2019
The project includes street improvements and public utility replacement including sanitary sewer main and laterals, water main and storm sewer. The gravel base, curb and gutter and asphalt will be removed and replaced. Driveway aprons will be constructed with concrete. Existing sidewalk will be spot replaced as needed.
This project will install sanitary sewer backwater valves to provide properties with additional protection from backups. An example of what the backwater valve will look like can be found here: Backwater Valve
FAQ's for backwater valves:
What are they?
- A vertical standpipe pipe with a flapper valve that prevents wastewater from flowing into a basement (see display)
Where are they located?
- Near to sidewalk
Why are we proposing them here?
- Homes built prior to 1980 are not protected by a functional sewer backwater valves and are at risk of backups
- May prevent wastewater from a surcharged sewer or water from a water main break from entering the basement
- Extreme wet weather events are becoming more common in Madison and as such, the frequency of backups into basements not equipped with a functional backwater valve is likely to increase.
How much do they cost?
- City will pay 75% of the backwater valve and installation cost (City cost share amount up to $1,500)
What is needed for maintenance?
- Backwater valves like sewer laterals are owned by the property owner and require scheduled maintenance to ensure proper function.
Do property owners have to participate?
- No, property owners who do not want a backwater valve installed with the street reconstruction project can contact the project manager listed below and remove the backwater valve from the project.
