Flood Plain Maps courtesy of DOT and DEP, Montgomery County, MD
During storms, water flowing into Wheaton Branch backs up as it reaches the undersized Dennis Avenue bridge, just north of the Wheaton Branch stormwater ponds. The result is significant flooding for residents in the area north of the bridge.
The existing 100 year floodplain map shows the flooding that affects residential properties and roadways for several blocks. Through an extensive re-engineering project, the proposed 100 year flood plain would be lowered and widened to direct floodwater away from homes along Glenhaven Drive and other nearby streets.
Ed Murtagh, longtime FOSC member and social media creator, created these videos 1) demonstrating how stormwater ponds function using the University Boulevard Stormwater ponds as an example, and 2) the components of the planned flood mitigation project at Wheaton Branch.
