Naswa Resort (Laconia, NH)
Evaluating Relationship between Flooding Damage and Construction on Adjacent Property
The Naswa Resort, located in Weirs Beach, Laconia, New Hampshire, has been owned and operated over several generations by the same family since it was founded in 1935. Since 2004, when logging and construction activities began at the abutting property, the Naswa Resort has been plagued by a host of flooding and water-related damage issues that were unlike anything previously observed in the Resort’s 75+ year history. Repair costs for flooding-related damages have exceeded one million dollars. EGGI was retained to evaluate possible causes for this flood damage.
EGGI reviewed a number of reports, plans, and photographs to evaluate pre-existing site conditions, proposed development design features, and documentation of flood damage. EGGI hydrogeologists performed field mapping activities at the Naswa during the fall and early winter of 2011. Detailed mapping of the surface water drainage features was performed using 2010 aerial photographic base maps. EGGI also evaluated land cover, such as the condition of the forest, presence of impermeable surfaces, and land use changes that affect stormwater generation.
EGGI's hydrologic and watershed approach to investigating the flooding at the Naswa Resort identified three overall factors that contributed to the flooding of the Naswa facilities. EGGI’s detailed report of its findings contributed to a legal action that served to recover funds to mitigate property damage.
