Document Description
The purpose of the project is to replace the existing failed 36-inch diameter corrugated steel pipe culvert beneath Springbrook Road and repair the roadway, including strengthening the compromised roadway embankment and adding drainage structures for long-term maintenance activities. The culvert conveys water from properties bordering where the pipe crosses the County maintained roadway. The culvert inlet and outlet occur on adjacent residential properties. Real Estate transactions, utility relocations, temporary traffic control or road closure, tree/vegetation trimming or removal will be necessary in support of the project. Emergency vehicles will have access at all times. Construction is anticipated to begin in 2025 or 2026 and take approximately 30 working days.
