Background 

This project will repair a failing storm sewer outfall between 24th Road North and the Analostan Homeowners Association Property which flows into Donaldson Run.  The project will also stabilize the eroded stream channel below the outfall feet to a point that connects to a previously constructed stream restoration project.  A section of storm sewer pipe was also previously re-aligned as part of the project.  The stream stabilization will include the installation of step pools to slow the energy of the stream flow and rock walls to protect the stream channel.   

Construction Schedule 

Some tree removal will take place starting the first week of March, 2023.  Construction is expected to begin in April/May 2023. The construction time frame is 9 months.  Construction access will be from 25th St North and the Missionhurst property.
