Dot size ∝ opportunity score. Parcel outlines & owners are live Regrid data and appear when you zoom in. Public parcels are shown for adjacency leverage — they are not targets.
Read me first. This is an access-strategy prototype, not a "where to fish" map. It does not assert any public right of access. Private uplands require permission; active rail is a barrier, never a route. Owner names shown are corporate/institutional; individual household owners are not published here. Candidate scoring is an analyst estimate pending parcel verification.
