2005-04-03 to 2005-04-05 · Bucks, Pennsylvania

Wider weather episode

For the second time within seven months a greater than 50-year storm affected the Delaware River Basin and its tributaries. In all, about 5,715 homes were evacuated along the Delaware and Susquehanna Rivers in Pennsylvania. Pennsylvania Ed Rendell quickly declared a state of emergency and made money available to the Pennsylvania Emergency Management for flood related needs. Many homes and businesses that were flooded because of the remnants of Hurricane Ivan, were flooded again. The crests along the Delaware River were even higher than in September 2004 and were the highest crests since 1955. In many places, it was the second or third highest crest on record for the Delaware River. In Monroe, Northampton and Bucks Counties, about 2,200 homes and businesses were flooded, 40 homes were destroyed. Many of the homes and businesses that were flooded, had flooding into the first floor of their dwellings. About 4,300 people were evacuated, with the greatest number in Bucks County. Shelters were opened in schools, fire houses and churches. Both the Red Cross and Salvation Army assisted with the evacuations and distributing food and drinks. Many major roads were closed. Some will be closed for months because of the damage. A dozen low-lying bridges from Trenton north were closed and damaged by the flooding. Many schools along river towns were closed on Monday April 4th, some also on Tuesday April 5th. The Delaware Canal took another major hit as the Delaware River merged with the canal. Damage from the remnants of Ivan and the latest storm was estimated at $40 million dollars. In the three county area total damage from this storm was estimated at $120 million dollars. The worst damage was reported in Easton (Northampton County), Yardley and New Hope (Bucks County). Miraculously there were no deaths or major injuries.Residents and businesses found raw sewage that backed into water-logged cellars. Many furnaces, water heaters, electrical panels, washing machines and dryers were destroyed. In many places, everything that was stored below ground level was destroyed. The flood waters dislodged propane and oil tanks. Some basements were contaminated with oil. First floor damage included ruined hardwood floors, furniture, carpeting, vinyl flooring and dry walls. The homes that were greatly affected had their electricity and gas service turned off and in many instances had to get the former replaced. Private wells had to be tested for contamination.The heavy rain loosened the ground and caused trees to be knocked down and carried down river along with waste receptacles, propane tanks and beer kegs. As river levels rose, they damaged the low-lying bridges across the Delaware River. Damage to the bridges was estimated at $1.5 million with the greatest damage and longest closure to the Washington Crossing Bridge between Bucks and Mercer Counties. On April 15th, President George W. Bush declared a major disaster area in Northampton, Bucks and Monroe Counties. This opened the door for federal aid for homeowners and businesses. Persons could get grants for temporary housing and to clean and rebuild their homes. Homeowners and businesses were now eligible for low interest loans to cover uninsured property losses and other federally funded programs.In Bucks County, the heavy rain caused widespread poor drainage flooding on the 2nd and stream and river flooding from the 2nd through the 5th. Rain started late in the evening on the 1st and continued throughout the day on the 2nd. The rain fell at its heaviest during the afternoon of the 2nd. The rain tapered off to some spottier light rain or drizzle during the evening and overnight and ended during the morning on the 3rd. Storm totals averaged around 3 inches. The county was hit by both inland smaller creek flooding as well as flooding along the Delaware River. The majority of the damage occurred in municipalities along the Delaware River as well as the Delaware Canal. Within the county, 1,066 homes were destroyed or damaged and 116 businesses suffered major damage while many others suffered lesser damage. About 3,000 people were evacuated along the Delaware River and Neshaminy Creek. About 1,400 homes and businesses were without electrical power along the river for safety reasons. About 200 of those homes also had gas service stopped. All power was restored as of the 6th, except for about 400 homes that required repairs to their electrical systems. In all 8 county homes were destroyed (moved off their foundations), 489 homes suffered major damage, 306 suffered minor damage while 263 homes had lesser minor damage from basement flooding. Damage to homes and businesses was estimated at $20 million dollars while additional damage to the entire Northampton and Bucks Counties length of the Delaware Canal was estimated at $30 million dollars. Walls along the canal were knocked down, locks and gates were damaged and downed trees exacerbated the damage. Repairs could take years to finish. Many roads were closed and damaged including large stretches of River Road (Pennsylvania State Route 32) and Pennsylvania State Route 611. While most of the low-lying free bridges were reopened by the 6th, the Washington Crossing Bridge was closed much longer as a 3 foot by 8 foot section of one of the piers was eroded by the flood waters after a suspected dumpster struck the pier. About 7,400 vehicles use the bridge daily between Upper Makefield and Hopewell (Mercer County) Townships.In Riegelsville Borough, 500 people were evacuated as flood waters extended west of the canal. Twelve people were rescued from submerged homes. About one quarter of the homes in the borough suffered flood damage and seven roadways were shut. In Nockamixon Township, a half mile stretch of River Road will be closed indefinitely as its shoulder was washed away. In Bridgeton Township, the Upper Black Eddy area had about 140 homes that suffered damage. In Tinicum Township, about 100 homes were damaged and a large stretch of Uhlerstown Road was washed away. In New Hope Borough, the entire downtown area was evacuated as well as the Waterworks and Waterview Developments. The historic Bucks County Playhouse had up to ten feet of water along its outer walls. Other Main Street businesses had up to 7 feet of water on their first floors. A few of the downtown restaurants were expected to be closed for months; the rest were reopened on the 10th. In Upper Makefield Township, five homes were destroyed as the Washington Crossing area was inundated with up to 8 feet of water. In Yardley Borough, all residential areas east of the Delaware Canal were evacuated. About 400 homes were damaged and damage in the borough alone was estimated at more than one million dollars. Flood waters extended west of the Delaware Canal. Three homes were destroyed. In Lower Makefield Township, about 100 homes were damaged. A breach in the Delaware Canal caused flood waters to inundate Morrisville Borough. Inland, flooding along the Neshaminy Creek forced the closure of Pennsylvania State Route 413 and Bridgetown Pike. Flood waters damaged a small bridge in Doylestown. The following are the gaged crests along the Delaware River from north to south in Bucks County.

The flooding heavy rain was caused by a low pressure system that moved from the southern Gulf Coast States on the morning of April 1st northeast to the eastern Tennessee Valley during the evening of the 1st, to far western Virginia just after Midnight EST on the 2nd, into central Virginia at 7 a.m. EST on the 2nd, near Washington, D.C. at 1 p.m. EST on the 2nd, near Lancaster, Pennsylvania at 7 p.m. EST on the 2nd, near Scranton, Pennsylvania at 1 a.m. EST on the 3rd, over the Finger Lakes in New York at 8 a.m. EDT on the 3rd and into eastern Lake Ontario at 2 p.m. EDT on the 3rd. The strong southeast flow preceding the low pressure system was able to entrain Atlantic Ocean moisture in addition to the Gulf of Mexico moisture into the system. The southeast flow also was ideal for orographic lifting in the Poconos and other higher terrain. The flooding was exacerbated by the already wet soil conditions due to heavy rain on both March 23rd and 28th. In addition, along the Delaware River, snowmelt in the upper basin in New York State and because the New York City Delaware County, New York reservoirs were already at capacity added to the flooding.
