The flood damage to the boardwalk occured between 7pm and 9pm the evening of Thursday, August 7, 2008, when an unrelenting storm front dropped about 4 to 5 inches of rain in a two hour period. These pictures were taken the following morning, August 8, 2008.
By the afternoon of August 8 construction crews were already hard at work on emergency repairs. A 36" wide regional sewer line that paralleled Lakeside Avenue ran right through the damaged area. The flooding had left the line unsupported from below and in imminent danger of failure. A rupture to the line would have caused an environmental disaster, as raw sewerage would have poured into the Lake. Fortunately, by the following day the line had been secured by the emergency work crews.
The line, known as the "Meredith Interceptor" carries 500,000 gallons per day and is part of the Winnipesaukee River Basin Program. The program was authorized in 1972, construction began in 1976, and the Meredith Interceptor, "a main artery for carrying sewerage from Meredith and points along the southerly shore of Meredith Bay to Weirs Beach", was completed in 1983. The Meredith Interceptor follows alongside the railroad tracks from Lakeside Avenue to the western side of Paugus Bay, then continues onward to Laconia and ultimately to the wastewater treatment plant in Franklin.
Shortly after the end of the boardwalk, the Meredith Interceptor merges with the Gunstock Interceptor from Gilford in the vicinity of the Endicott Rock Park parking lot. A concrete structure marks the exact spot. The Gilford Interceptor diverges from Route 3 just before the Aquedocatan stone bridge. Passing about 50' to the north of the bridge, the Gilford Interceptor crosses 5' deep underneath the Weirs Channel to the grassy area of Endicott Rock Park.
In addition to the main damage there was also minor damage in about 8 places to the embankment supporting the southern section of the boardwalk.
By Thursday, August 28, 2008, in the area where the major damage had occurred, repairs were completed to the railroad bed and the embankment, but not to the boardwalk or the stairway to the public docks.
There remains a large 80 foot gap in the boardwalk which is scheduled to be repaired sometime in 2009. The stairs to the public docks will be replaced concurrently with the boardwalk repair.
Funding of the repair project remains an issue. FEMA (the Federal Emergency Management Agency) has committed to 75% of the cost of the repair; however, FEMA will only fund repairs to the area of major damage to the boardwalk, while the City of Laconia is seeking additional funding for repairs to the southern section of the boardwalk where minor damage occurred. In addition, the City is looking to strengthen the boardwalk in both areas to insure that damage from any future flooding is minimalized. This would entail "new concrete footings and grade beam atop a steel sheet pile wall." The estimated entire cost of the project as envisioned by city officials is in the range of $1.3 to $1.5 million dollars.
