(Photos by Julia Wiese) The pounding rain that flooded the Puget Sound region Monday came during a perfect storm of factors that overwhelmed the capacity of the City of Edmonds’ stormwater system, Public Works and Utilities Director Phil Williams said Wednesday. “This was the most serious and widespread urban flooding we have experienced for many years,” Williams said. “Some of our senior stormwater personnel say it was more intense than they can recall in the last 20+ years. We are still looking at the data to see if we can confirm that statistically.”
