This Landslides data contains point and other attributes for historic and recent landslide locations in New Jersey mapped by the New Jersey Geological Survey (NJGS). The landslides have occurred in many parts of the state and include slumps, debris flows, rockfalls and rockslides. Landslides in New Jersey are a geologic hazard in areas with steep to moderate slopes or geologic units prone to failure. They cause damage to utilities, property, and transportation routes. The average annual direct and indirect cost of New Jersey landslides is likely in the hundreds of thousands of dollars. New Jersey landslides have also caused fatalities and injuries. The landslides are caused by heavy rains, weathering, ocean waves, quarrying and construction activities.

These maps delineate the entire Puget Sound shoreline by geomorphic type. The primary purpose of the mapping was to identify feeder bluffs, eroding shorelines that are important to maintaining nearby beaches. Knowledge of the distribution of these features can be used by local planners and resource agencies to better manage Puget Sound shorelines. The study emphasized mapping of coastal bluffs, but also extended to a wide range of other coastal landforms, including rocky shores, river deltas, and small lagoons and estuaries. This mapping project is described in the following report, available from the Department of Ecology: MacLennan., A. Johannessen, J.W., Williams, S.A., Gerstel, W., Waggoner, J.F., and Bailey, A., 2013, Feeder Bluff Mapping of Puget Sound, prepared by Coastal Geologic Services, Bellingham, for Washington Department of Ecology, Olympia WA, 117 pp and map folio.
