Base elevations:
LiDAR values processed to Digital Elevation Model (DEM) - LAS files to Mass Point (MP) feature class; MP converted to Triangulated Irregular Network (TIN). TIN to DEM as ESRI GRID. Multiple collections mosaicked to single GRID - preserving best available datum and best resolution among all collections.
2016-01-01T01:00:00
RESAMPLE CELLS:
For GRID...
Upsample horizontal resolution to two meters.
2016-01-01T02:00:00
Adjust DEM in accordance to sea-level change estimate:
For GRID...
DEM minus scenario specific (Year, Tide) SLC Value Localized SLC: NOAA tidal reference station contributes elevation readings (Station ID: 8575512; MSL: 5.24, MHHW: 5.95).
Station elevations are calibrated to land-based elevations representing the NAVD88
(Vertical Correction MSL to NAVD88 = -0.05).
A 3.32mm/yr correction for glacial isostatic adjustment and land subsidence brings USACE observations (1992) to 2015
(Project Year = 0.25).
Account for variation between MSL and MHHW
(Tide = 0.71).
USACE sea level change estimate:
Year; Tide: SLC Value; Tide: SLC Value
2015; MSL: 0.00; MHHW: 0.71
2050; MSL: 2.08; MHHW: 2.79
2100; MSL: 5.70; MHHW: 6.41
[MSL SLC = (VC + PY + USACE)]
[MHHW SLC = (VC + PY + USACE + T)]
2016-01-01T03:00:00
FILL SINKS:
For GRID...
Multiple by 1000 reclassify values ([LESS THAN ZERO = 0; ELSE: VALUE = VALUE]) cast datatype(int) to float divide by 1000
2016-01-01T04:00:00
SLC adjusted DEM serves as elevation dataset for a Level 1 Coastal Only HAZUS-MH (FEMA) Flood analysis. The countywide study's shoreline is restricted to that of the Deal Island Neck. Breakpoints segment the shorline to capture flooding sources, locations, and heights outlined in the county's FEMA Flood Insurance Study.
Flooding Source; Location; Annual Chance Event: Eleveation (ft) NAVD88
Chesapeake Bay; Patapsco River; 10%: 3.3, 4%: 4.31*, 2%: 6.0, 1%: 7.3, 0.2%: 9.9
Chesapeake Bay; Severn Run; 10%: 3.3, 4%: 4.09*, 2%: 5.4, 1%: 6.4, 0.2%: 8.6
2016-01-01T05:00:00
GET AREA VULNERABLE TO SLC:
For GRID...
Reclassify values ([LESS THAN EQUAL TO SLC Value = 1; ELSE: VALUE = "NODATA"]) convert raster output to vector create feature from vector polygons intersect Chesapeake Bay connected flowlines. BAY CONNECTED FLOWLINES: build Network Dataset from (Select Flowlines from National Hydrography Dataset(high-resolution) where inersect County border) select features from National Hydrography Dataset(high-resolution) - NHD Area and NHD Waterbody - comprising County's physical boundary; select junctions from Network Dataset where intersect physical boundary features; load select junctions as locations and solve service area analysis where impedance is 30,000, polygon not generated, lines on but not overlapping. solution is 'Chesapeake Bay connected flowlines'.
2016-01-01T06:00:00
CREATE DEPTH FOR AREA VULNERABLE TO SLC:
For GRID...
Extract values where mask is feature - polygons intersect Chesapeake Bay connected flowlines For extracted area... subtract SLC Value multiple by negative one(-1)
2016-01-01T07:00:00
RECLASSIFY STILLWATER ELEVATIONS:
For Depth GRID...
Reclassify values with ranges: [<0' to 0.10' = 0, >0.10' to 0.5' = 1, >0.5 to 1' = 2, 1' to 2' = 3, >2' = 4]

2016-01-01T10:00:00
IDENTIFY ELEVATED SURFACES AND UPDATE GRIDCODE:
For Identity Analysis output...
with RAW DEM as base layer... split segments where overlay hydro-enforced LiDAR values and set 'bridge = 1'
select where bridge = 1... new feature'bridge'. switch selection... new feature 'notBridge'
dissolve 'bridge' on FID (multi-feature line possible as IDENTITY ANALYSIS breaks feature on classified depth range)
SPATIAL JOIN (select from 'notBridge' where INTERSECT 'bridge') and 'bridge with field mapping set to return MAX gridcode from 'notBridge' selection
join Spatially Joined features to IDENTITY ANALYSIS output... calculate IDENTITY ANALYSIS [GRIDCODE] = SPATIAL JOIN [GRIDCODE_MAX]
DROP JOIN
