The Esopus Meadows Preserve is a part of the Scenic Hudson Park System in Ulster Park, New York. In 2014, Scenic Hudson sought to improve the Preserve by adding a pavilion for families and hikers alike to rest, have a picnic, or simply just take in the beautiful scenery. Unfortunately, the project site contained an organic soil layer at 4 feet below grade leaving traditional footings susceptible to settlement. In order to resist this potential settlement, Foundation Stabilizers installed a total of 32 helical piles of varying size. The project was finished on time and on budget and the Pavilion has been in use since 2015.
