Systems Integration

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).
