Summary:
Milestone Estimated Actual
The City of Arlington currently has six stream gauges. These gauges Completion Completion
collect important information such has rainfall accumulation, Task 1 Nov. 2021
rainfall increments, and water levels. The stream gauge uses the Task 2 Jan. 2022
ALERT (Automated Local Evaluation in Real Time) 1 system which Task 3 May 2022
needs an upgrade as hardware improves. This real time data will
assist in response time for activating barricade infrastructure,
emergency operations, and engineering assessments. During FY
2021, the Floodplain Group will perform the following three tasks:
 Task 1: Upgrade two existing stream gauges to Automated
Local Evaluation in Real Time 2 (ALERT 2) system to
increase the accuracy and performance of flood detection
systems.
 Task 2: Identify low crossings based on watershed studies
and Emergency Operations to determine two new
locations to install stream gauges.
 Task 3: Identify grants and possible funding opportunities
to assist in installing at least six additional gauges within
the City limits.

This data collected by the stream gauges benefits the citizens of
Arlington by informing them about active flood risks to take
appropriate action. The implementation of a flood hazard
notification system will reduce the potential loss of life or injury due
to flood hazards from overtopped roadways. The collected data
also assists in identifying flood protection projects to be
incorporated into the Stormwater Capital Improvement Plan.
