Property Data

Reassess status of property data with Connor
Determine if raster based analysis is feasible
Determine if area threshold is necessary

Hi Connor - what do you think of this approach?

Calculate Acres in GIS to make sure acreage is accurate for the projection we are working in
Dissolve multipart all CPAD to a single shape
Intersect with parcel data
Dissolve output from step 3 on APN
Calculate Acres of the output from step 4
Join by attribute the output from step 5 onto the output of step 1 (the parcel data). The join field would be the APN
Divide protected acreage (from the joined table) by the total parcel acreage, multiply by 100
Remove parcels with >70% protected (this is where we may need to adjust) does this miss some parcels we should have removed? Would >50% remove some we should have left?)

Hand-off from Connor:
N:\Projects\Atlas\data\parcels\round2_analysis\scripts

county_loop_test is the current workspace, county_loop has the full list of county abbreviations that will eventually be added to the final script.

Finish Protected Area Removal

• Check all joins by calculating difference
• Export table with PARCEL_ID, PA_ACRES, and pa_percent
• arcpy join small table to lg_par shapefile attribute
• decide on cutoff - explore SD county
• export non-pa parcels

Create property rasters

• Dissolve non pa parcels on owner
• Give unique ID
• convert to raster, keep extent identical (in R)

Deal with boundary issues

• select parcels within 5m of county boundary
• export as shapes
• merge to one shape - all counties
• dissolve on owner (singlepart - max acreage_
• subset to just parcels that changed size by calculating new size and identifying those with larger size than the MAX_acreage)
• covert to raster

Populate property data with

• acres within each category
• mean, min, max of each SDM
• acres of each connectivity category
• average HMI
• dist to PA
• Acres of ICLUS
• dist to ICLUS
• dist to DAC
• mean carbon
• acres of 100yr flood
• drinking water watershed
• acres in fmmp cats
• average crop value
