Ladd's Addition Sewer and Green Street Project

Updated November 18, 2019Sign Up for email updates button

Environmental Services is continuing to design a project in a portion of the Ladd’s Addition neighborhood to install, replace, and upsize approximately 3,500 feet of public sewer pipes.  Environmental Services is also proposing to construct 16 green street planters to manage stormwater runoff from streets, roofs and parking lots. The sewer and stormwater improvements will increase sewer capacity, manage stormwater more naturally, and reduce the risks of street flooding and sewage releases to homes, businesses and streets.

Utility Locates

In the next few weeks, city crews will dig small holes in the street to confirm the location of utilities near proposed construction locations. The industry term for this work is “potholing”. What the engineers learn from this process will help them determine construction locations and methods.

What to Expect

Utility locates are scheduled to occur sometime in November and December between 7:00 a.m. and 6:00 p.m. Work crews will drill eight-inch wide holes in street pavement and unpaved public right-of-way areas at approximately five locations. Crews will fill the holes immediately after the drilling is completed. There may be brief periods of noise, dust and mild vibration during drilling.

Design Update

A public meeting occurred in May of 2019. During this meeting and in the months since, we have received many comments and feedback from neighbors and property owners regarding the project. Specifically, we have worked with many adjacent property owners regarding the green street planters, adjusting the designs, doing additional ground investigations, and removing six green street planters from the project. Specifically, two were removed from SE Cypress, three removed from SE Ladd Ave between Division and Lavender streets, and one from SE 16th and Division. All the green street planters are located within planting strips, except for one curb extension design at SE Harrison and Hemlock. Neighbors worked closely with Environmental Services on this one to preserve the historical layout of Ladd’s Addition.

Schedule and What's Next 

Construction for the Ladd’s Green Street and Sewer Project is expected to start spring 2021. After the holidays, we plan to hold another public meeting and will be presenting to the Hosford-Abernethy Neighborhood District. More information to come later.
