Description:
Note: IMS-30 comprises map image PDFs for the NE, SE, and SE
quarter quadrangles. The IMS-26 map image PDF, of the NW quarter quadrangle, is
included with this publication. The OregonCity_1.gdb geodatabase
includes spatial and tabular data for all four quarter quadrangles.
Abstract:
This layer is an inventory of existing landslides deposits
in the Oregon City USGS 7.5' quadrangle. Each landslide deposit shown on this
map has been classified according to a number of specific characteristics
identified at the time recorded in the GIS database. The classification scheme
was developed by the Oregon Department of Geology and Mineral Industries (Burns
and Madin, 2009). Several significant landslide characteristics recorded in the
database are portrayed with symbology on this map.
The specific characteristics shown for each landslide are the activity of landsliding, landslide features, deep or shallow failure,
type of landslide movement, and confidence of landslide interpretation. These
landslide characteristics are determined primarily on the basis of geomorphic
features, or landforms, observed for each landslide.
Purpose:
The landslide inventory is one of the essential data layers
used to delineate regional landslide susceptibility. This landslide inventory
is not regulatory, and revisions can happen when new information regarding
landslides is found or future (new) landslides occur. Therefore, it is possible
that landslides within the map area were not identified or occurred after the
map was prepared.
This inventory map was prepared by following the Protocol for Inventory Mapping
of Landslide Deposits from Light Detection and Ranging (Lidar)
Imagery developed by Burns and Madin (2009). The three primary tasks included
compilation of previously mapped landslides (including review of SP-34 (Hofmeister, 2000) and SLIDO (Burns and others, 2008)), lidar-based morphologic mapping of landslide features, and
review of aerial photographs. Landslides identified by these methods were
digitally compiled into a GIS database at varying scales. The recommended map
scale for this data is 1:8,000 as displayed on this map. Each landslide was
also attributed with classifications for activity, depth of failure, movement
type, and confidence of interpretation. The landslide data is displayed on top
of a base map that consists of an aerial photograph (orthorectified)
overlain on the lidar-derived hillshade
image.
This landslide inventory map is intended to provide users with basic
information regarding landslides within the quadrangle. The geologic, terrain,
and climatic conditions that led to slope failures in the past may provide
clues to the locations and conditions of future slope failures, and it is
intended that this map will provide useful information to develop regional
landslide susceptibility maps, guide site-specific investigations for future
developments, assist in regional planning, and mitigation of existing
landslides.

This map depicts an inventory of existing landslides based
on published and unpublished reports and interpretation of topography derived
from lidar data and air photos. The inventory was
created following the protocol defined by Burns and Madin (2009). This map
cannot serve as a substitute for site-specific investigations by qualified
practitioners. Site-specific data may give results that differ from those shown
on this map.
Use_Constraints:
Restrictions and legal prerequisites for using the data set
after use is granted. These include any access constraints applied to assure
the protection of privacy or intellectual property, and any special
restrictions or limitations on using the data set. The maps cannot serve as a
substitute for site-specific investigations by qualified practitioners.
Site-specific data may give results that differ from those shown on the maps.

CONFIDENCE OF INTERPRETATION: Each landslide should be
classified according to a "confidence" that the mapper
assigns based on the likelihood that the landslide actually exists. Landslides
are mapped on the basis of characteristic morphology, and the confidence of the
interpretation is based on the visual strength of the morphologies. As a
landslide ages, after its most recent movement, weathering (primarily through
erosion) degrades the morphologies produced by landsliding.
With time, landslide morphologies may become so subtle that they resemble
morphologies produced by geologic processes and conditions unrelated to landsliding. Some landslides have several different types
of morphologies associated with them. A good way to define certainty is through
a simple point system (see table below) associated with these features. The
point system used is based on a ranking of four primary landslide features with
a ranking of 0 to 10 points per feature. For example, if during mapping, the
head scarp and toe of a landslide were identifiable and had very strong visual
strength, the mapper would apply 10 points for the
head scarp and 10 points for the toe equaling 20 points, which would be
associated with a moderate certainty of identification.
