Definitions
Vacant and underutilized classification rule
Vacant means county IMPRVT_VAL is 0. Likely underutilized means county IMPRVT_VAL is greater than 0 but ≤ 20% of county LAND_VAL. Active means improvement value exceeds that threshold.
Method
Opportunity score and cluster formation
Score weights vacancy or underutilization, lot size, low improvement value, lower assessed value, civic/nonprofit ownership, and QOZ status. Clusters group high-score parcels by nearby centroid grid cells, then size markers by parcel count.
Operations Manual
How to Use the Newark Parcel Dashboard
A complete guide covering filtering, parcel classification logic, map operations, selection tools, AI assistant capabilities, and data export options.
01
Start With the Command Palette
Press ⌘K or click Filters in the top bar to open the command palette. Use status, ownership, geography, zoning, and value range controls to narrow the visible parcel universe. All KPIs, charts, and the map update instantly.
02
Understand Utilization Status
Vacant means county IMPRVT_VAL is 0. Underutilized means IMPRVT_VAL is greater than 0 and ≤ 20% of LAND_VAL. Active parcels exceed that ratio. These are derived from county assessment data, not Regrid USPS vacancy flags.
03
Navigate the Map
Click any parcel polygon to open the detail popup. Use "Full record" to inspect every available field. Toggle clusters (C button) to see assemblage opportunities. At low zoom, fast point rendering is used — zoom in for full polygons.
04
Select and Track Parcels
Check the box beside any high-opportunity parcel in the sidebar list, or use the "Select" button in the popup. Selected parcels persist across filter changes and can be exported independently from the full filtered set.
05
Export and Report
Export all visible parcels as CSV, export only selected parcels, generate a JSON data package, or produce a full HTML report with KPIs, opportunity tables, and current filter conditions. Use the Export dock that appears when parcels are selected.
06
Use the AI Parcel Assistant
Click the AI button to open the intelligent assistant. Ask questions in plain English: "how many vacant parcels?", "show R-3 parcels", "ownership breakdown", "report for nonprofit". The assistant reads the live dataset and answers deterministically — no API key needed.
Data Explorer
Browse, sort and export the current filtered parcel dataset.
