After yet another heavy rainstorm last week, a section of Northern Liberties experienced localized flooding as result of an overwhelmed stormwater system.
This area contains the historic Cohocksink Creek and is the focus of a long-term infrastructure improvement project. Traditional sewer expansion and green stormwater tools will improve the capacity of the local system while reducing the amount of water entering sewers.
Philadelphia Water is aware of last week's flooding and on-going issues, and we're working with the community to address immediate concerns as we implement a plan to improve conditions in the long haul.
You can see a summary of plans to address flooding in the vicinity of Wildey and N. American streets here and here.
Impacted residents are also encouraged to attend a community meeting on the Northern Liberties Storm Flood Relief Program. Philadelphia Water representatives will discuss flood reduction efforts at the South Kensington Neighborhood Association,1301 N. 2nd St., on Tuesday, July 14 at 6:30 p.m.
Stress on the Sewers: Is June Philly's New Monsoon?
The July 9 storm dumped nearly an inch of rain in just under 10 minutes—the heaviest of the month so far—and came at a time when the Delaware River was at its highest tide level.
It’s been a rather wet summer so far, and that means additional stress for stormwater infrastructure. After a historically dry May, June made up for it with a vengeance. Only two years have seen a wetter June in the city, according to records dating to 1872.
The wettest June ever was in 2013, followed by 1938 and 2015 with 8.88 inches. The National Weather Service lists June’s rain average as 3.43 inches.
It’s all part of a trend that has seen six of the rainiest Junes EVER occur in the city in just the last dozen years:
June 2013: 10.36 (1st)
June 2015: 8.88 (3rd)
June 2003: 8.08 (4th)
June 2006: 7.95 (6th)
