We strongly encourage you to subscribe to receive CSO No. 12 Project alerts using our NotifyMe service. Periodic project updates will be posted to this project page as well as emailed to subscribers.

Will My Property Be Affected?

MAYBE. The City’s Combined Sewer Overflow (CSO) projects are comprehensive in nature. They include the replacement of sewer lines, water lines, and the street’s drainage system. Depending on the character of the area in which you live, combined with input from you and your neighbors, existing sidewalks may be upgraded, or new sidewalks may be added. As we plan for the future of Lebanon, we are working towards unifying Lebanon’s street network. In this effort, we are striving to create livable/walkable neighborhoods. Your input is highly desired!

Please understand that we will always be mindful and respectful of the historical background of your neighborhood. We know you have concerns about the possible impacts to your land and trees.  Please know that we will strive to evaluate all aspects of your property in advance of construction. Any changes or potential impacts will be discussed with you.

It is also important to note that whenever/wherever possible, we work within the confines of the City’s Right-of-Way. However, there may be times when easements are needed from you to complete the project. Again these will be discussed with you in advance of construction.
