The cleaned ground, by suburb

By the count of parcels carrying a cleanup on the file.

Each remediated parcel files under the suburb its exterior’s middle sits in, the count of parcels, their hectares, and how many carry the verified mark. A cleanup on the file is the register’s word, not a clearance.

The latest on file

Questions, answered briefly

What is the remediation register?

The cleanup file. Christchurch’s remediation layer holds 260 parcels, about 85 hectares, where the record says contamination was dealt with: 211 dug out and carted away, 25 managed in place under a long-term site plan, the rest capped, sealed or treated. It is the other half of the hazardous-activities register, the parcels that did something about it.

Does a remediation record mean the ground is clean?

No, it means a cleanup is on the file. 57 records are marked verified; the rest are the register’s own description of work done, "soil removed", "contamination removed", "asbestos removed", without the file confirming it held. And "managed" records mean the contamination stays, contained, under a plan that outlives the cleanup.

What does "dug out" mean?

Exactly that, the file’s own phrase is usually "soil removed" or "contamination removed": the ground was excavated and carted away, often to a lined landfill. It is the commonest cleanup on the register. The rarer ones are sealed, a cap of concrete or clean fill poured over the contaminated ground, and managed, where the contamination stays and the site carries a Long Term Site Management Plan.

How does this sit alongside the hazard register?

A parcel can sit on both, the HAIL register records the work that can leave something behind; this register records the cleanup. The two pages cross-reference where the records link. A point’s own answer is at /before.

The record behind this

Christchurch City Council’s open land layers, the ContaminationRemediation layer of OpenData/LandCharacteristic. 57 records are marked verified; the rest are the file’s own word that the work happened. A remediation record is a cleanup on the file, not a clearance certificate, and "managed" means the contamination stays, held by a plan. The work that can leave something behind is /hazards; a point’s own record is at /before; the tips are /landfills.
