Recent localized flooding from intense short periods of rainfall now challenge parts of our stormwater system due to issues of capacity and limited overland relief. Arlington is working toward flooding resilience through defining balance between private and public responsibility; scaling levels of flood protection and mitigation; and needs based investment.
Arlington’s stormwater system includes 10,000 storm drains, over 330 miles of storm sewers and 33 miles of natural stream channels.
