Early Warning System

This system provides information to residents and City staff 24-hours a day with updates every 15-minutes.   It alerts City of Shoreline staff if water reaches an elevation of 365 feet above sea level which corresponds to the top of the pipe draining Ronald Bog.  At that point, staff will visit the site and make an assessment.  It can also initiate reverse 911 if necessary.
