| Lost Creek Crest Characteristics 1999 | Field work to obtain data needed to develop this layer was
carried out by Shoreland Solutions during late August-early
September of 1996 and late August-early September of 1998.
Specifically, the location and elevation of reference
features including the vegetation line, toe of the
foredune, crest of the foredune, toe of the bluff, and
crest of the bluff were established at ~150 to 300 foot
increments along the study area shoreline. V8-video images
of the shoreline morphology was also collected at each of
these locations. All elevations are referenced to the
National Geodetic Vertical Datum (NGVD) of 1929. Categories
within the attribute field Toe Character are defined as
follows: talus (talus); no talus (not); open sand (os);
hydrophillic vegetation (hveg); beach grass (grass);
vegetated dune (vdune); driftwood (dw); cobble beach
(cobble); shore protection structure (sps); seawall (SW);
and riprap revetment (RR). Categories within the attribute
field Vegetation Cover are defined as follows: less than
25% (25-); between 25 and 50 % (25+); between 50 and 75%
(50+); and greater than 75% (75+). | 2_crest.met |

| Lost Creek Tax Lot Data 1999 | Tax Assessor's maps were obtained from the Lincoln County
Tax Assessor. The maps were digitized using ARCInfo. Once
digitized , each individual map was then referenced to the
1983 State Plane Coordinate System using ground control
points provided by the Lincoln County Surveyor. Once,
referenced, the maps were 'rubbersheeted' on top of the
aerial photographs Finally, the tax lot maps were joined
together using ArcView to create one continuous coverage
for each geographic subarea. | 2_txlot.met |

| Holiday Beach Reference Features 1999 | The reference feature line is a necessity of the spatial
analysis process, as a starting point for model script
calculations It's definition varies by shortype: In Bluff
Hazard Areas it is the landward most of the toe of the
bluff or the OSVL, in Slide Hazard Areas, the landwardmost
of toe of bluff or OSVL in high slide hazard areas, or
landwardmost of the most active headscarp (creats of bluff)
or OSVL in low slide hazard Areas. In Dune Hazard Areas it
is the landwardmost of 1st line of stable vegetation or the
OSVL, and in Inlet Hazard Areas it is defined as the
centerline of the Inlet. | 3_refftr.met |

| Holiday Beach Shoretype 1999 | Based on a review of maps and field reconnaissance
shoreline segments were classified as dune, bluff, slide,
stream or inlet. Dunes are segments of shoreline backed by
a sandy beach and dune. In this setting the extent of
short-term shoreline change attributable to episodic wave
attack events is the primary factor affecting shoreline
stability. Bluffs are segments of shoreline backed by a
sandy beach and bluff. In this setting the extent of
short-term shoreline change attributable to episodic
small-scale mass wasting events is the primary factor
affecting shoreline stability. Slides are segments of
shoreline where slide scarps, hummocky topography, and
other morphologic features commonly associated with
landslides back a sandy beach. In this setting the extent
of short-term shoreline change attributable to episodic
large-scale mass wasting events is the primary factor
affecting shoreline stability. Inlets are segments of
shoreline adjacent to and influenced by unaltered tidal
inlets and their associated shoals. In this setting the
extent of shoreline change attributable to inlet migration
is the primary factor affecting shoreline stability | 3_shrtyp.met |

resolution of ~1.33 feet per pixel. Each TIFF image has an
accompanying 'world file' (.tifw or .tfw) which gives the
affine coordinate transformation coefficients for the
specific image. The original TIFF images were processed in
ArcInfo. Image processing referencing the TIFF image to the
1983 State Plane Coordinate System, North Zone. It also
involved clipping the original images to a desired size
using the RECTIFY command with a defined BOX. A new 'world
file' was produced for each clipped image. | hbr.met |

| Aircraft Laser/GPS Mapping of Coastal Topography. | Laser beach mapping uses a pulsed laser ranging
system mounted onboard an aircraft to measure ground
elevation and coastal topography. The laser emits laser
beams at high frequency and is directed downward at the
earth's surface through a port opening in the bottom of
the aircraft's fuselage. The laser system records the
time difference between emission of the laser beam and
the reception of the reflected laser signal in the
aircraft. The aircraft travels over the beach at
approximately 60 meters per second while surveying from
the low water line to the landward base of the sand dunes. | lidar97.met |

| North Newport Slide Area 4 High Relative Risk Zone | The horizontal extent of risk zones was calculated for individual segments of shoreline using the formulas given below, where individual segments of shoreline are defined by shoreline type (dune, bluff, slide, inlet/creek). Where shoreline type is the same, creeks are commonly used to define boundaries between segments. Further information on the methodology used to define risk zones can be found in the set of documents titled Chronic Coastal Hazards Model Overlay Zone (Shoreland Solutions,1998) among others. Relative Risk in Slide Hazard Areas = Sslide + Sbluff. See Process Steps for more information. | s4hrrskz.met |
