Singing Sands, part of Bruce Peninsula National Park, is a popular destination for those seeking a day at the beach with a picnic and for those curious explorers wanting to learn about the ecosystem of the Great Lakes.
AECOM was retained by Parks Canada to provide landscape architectural, architectural, structural, mechanical, electrical and civil engineering services to design and prepare contract documents for the new day use area including a new reception and washroom building, observation deck and a new permeable parking lot complete with road crossing.
We developed solutions to manage several challenges the site presented. The groundwater is only one metre below the existing grade and all the subsoil is a silty sand which made excavation and dewatering difficult. We reduced the footing depths to 1.2 meters below grade and increased the finish floor elevation above the surrounding grade as much as possible while respecting the existing grades in the adjacent fen and sand dune area.
The existing granular parking lot established in the 1960s was removed down to subbase exposing the natural sand. This former parking lot is now a sand dune restoration area complete with plants consistent with the adjacent existing sand dune environment. The new parking lot was designed and detailed with permeable pavers to eliminate the need for storm sewer infrastructure.
