This page describes how EAS is integrated with other city systems.
Parcel Creation - DPW
Parcel creation occurs at DPW.
Every week night an automated extract-transform-load (ETL) job runs that loads new parcels into EAS.
A parcel as defined by EAS includes attribute and geometry data.
The DPW process for creating parcels is non-trivial and is documented here (need link).
Parcel Retirement - DPW
Parcel retirement occurs at DPW.
Every week night an automated extract-transform-load (ETL) job runs that loads retired parcels into EAS.
If a parcel is newly retired, addresses that are linked to the retired parcel are marked as "invalid".
An "invalid" address may be retired or may remain active.
The decision to retire an address is made by an EAS reviewer.
A reviewer may decide to keep an address active, even with a retired parcel, if there is permit activity on that parcel.
However, in most cases the reviewer will retire an "invalid" address.
The DPW process for retiring parcels is non-trivial and is documented here (need link).
Parcel Provisioning - EAS
In some cases, an address must be created immediately using a parcel that does not yet officially exist.
In these cases, an EAS Reviewer can "provision" a parcel within EAS.
This creates an unofficial parcel in EAS.
The EAS Reviewer then requests that the offcial parcel be created by DPW and must provide documentation from the assessor-recorder.
When the official parcel is created by DPW, the nightly ETL uses the block-lot to update the provisioned parcel, marks the provisioning as complete.
