Project site location
Overview
A 100 foot pipe segment is rusted and is in need of replacement. Alternatives were identified and evaluated. The goal of the project is to replace the pipe in order to maintain proper hydraulic function and stability while providing fish passage. Normally, old deteriorated pipe would be replaced with the same size pipe. However, because Molasses Creek is a stream known to be used by fish or meets the physical criteria to be potentially used by fish, state fisheries regulations require that the pipe meet current fish passage guidelines. The project is located in the vicinity of 134th Avenue Southeast and Southeast 163rd Street.
