Updated January 10, 2020

Environmental Services – your sewer and stormwater utility – will soon begin design of a project in the Council Crest Neighborhood to replace or repair aging public sewer pipes, better manage stormwater, and support healthy habitat.  Stormwater and ground water can enter sanitary sewers through roof drains, basement floor drains, foundation drains, basement sump pumps, driveway drains, cracked sewer laterals, or cracked sewer mains. By repairing existing pipes and more effectively managing stormwater, this project will help keep stormwater and groundwater out of the system, while safely carrying sanitary sewage to the treatment plant.

Survey and Inspection Occurring in Early 2020

Environmental Services will be surveying and inspecting sewer and stormwater infrastructure throughout the area in early 2020. You may see crews in the area surveying, inspecting culverts and pipes using CCTV cameras, and marking utility locations with paint and flags.

Most information-gathering activities during this project will occur in the public right-of-way. Some surveying and inspection will occur where the city has public sewer easements on private property, or on private property where there are no easements in place. City outreach staff will coordinate with affected property owners for access to private property for inspection and survey purposes.

You may see paint markings, stakes, and small flags in the ground identifying the locations of utilities and sewer and/or stormwater infrastructure.  Different marking colors identify the types of utilities that have been located.  If you are interested in learning more about what each color means, or for more information on the survey and inspection process, please visit


Survey and inspection work will take place throughout the winter of 2020 and in to the spring of 2020.  It is important to inspect stormwater infrastructure during wetter times of the year so that crews can evaluate how the facilities are working. 

The Council Crest Inflow and Infiltration Project is in an early evaluation and information gathering phase known as “pre-design.”  Design for the project will likely not begin until later in 2020 or early 2021.  Construction is not expected until 2022 or later. 

Environmental Services will continue to provide schedule updates via the project website, mailings, social media, and via email updates.
