Why is accurate address data important? What is the most important reason for maintaining complete & accurate address datasets?

Our City government keeps accurate address data for permitting, billing, and emergency response. Our GIS serves as the authority system of record for addresses so all other systems for City Departments, such as Fire, Police, Utility Billing, Engineering, Electric, Building, Environmental Utilities, and the City Permit Center, etc. rely on accurate addresses in GIS to perform their particular function well and be compatible with the other integrated systems. 

GIS also keeps our addresses as a point feature class, which allows us to build a composite address locator that first uses address point for the most accurate result, then street ranges for the next best guess. The composite address locator is used for various ad-hoc geocoding operations.

A central component of the City of Santa Fe Geographic Information System (GIS) is a comprehensive addressing system. Addresses are used by a variety of users, provide a convenient reference tool, and are an important part of City Services. As a result, it is critical for City operations that the addressing of parcels and buildings is done methodically and follows a set of standards.

My address is not posted?
It is the duty of the owner and/or occupant to place and maintain the correct address number. (Land Development Code (Ch 7-12.5))

How do I receive an Address Verification Form?
To request an Address Verification Form, please contact the GIS Staff and provide your address. Staff will then verify this with the information on record. If verified as a valid E-911 address, staff will provide an Address Verification Form. If there is a discrepancy, staff will work with you to resolve the issue. The Address Verification Form can be obtained in person or sent by email or postal mail.

What is the difference between an E-911 address and a postal address?
An E-911 address, or physical address, is the physical location (street address) of a property, residence, or business. The mailing address can be the same as the E-911/physical address, dependent on Post Office mail delivery protocols. Mail delivery can be to a PO Box, or as a growing trend, to a ‘cluster box’ (Multiple Box Unit or MBU) not placed at the physical location of a residence or business.
A valid E-911/physical address is required for all properties, residences, occupied structures, and or businesses in order for emergency service personnel to quickly and efficiently locate you in the event of an emergency.

Why is my address being changed?
E-911/physical addresses in the City of Santa Fe is determined by:
Address grid illustrated using 5000 ft cells containing
1000 potential addresses (one odd or even address every
10 feet). Addresses are calculated from the State Plane
Coordinate System (New Mexico Central) using the following formula:
((SPCY – 1705641.53) x 2) / 10 = North-South Address
((SPCX – 1732913.43) x 2) / 10  = East-West Address
Formula corrects for baseline at the Plaza Monument and adjusts for one odd or even address every 10 feet. 

Common reasons why addresses may change:
1) The driveway entrance has relocated to a different location on the same road, or in the case of a corner lot, the driveway entrance is on another road.
2) Even numbers are on one side of the road, and odd numbers are on the opposite. The address may be changed if the address number is out of sequence and/or if it is not on the correct side (an odd number on an even side or an even number on an odd side).
3) City of Santa Fe Ordinance 1987-5 requires that any road or driveway, whether public or private, that accesses four or more lots, occupied buildings, or residences, shall be named. Once this threshold is met, that road or driveway must be named. This will result in a road name and new addresses for all affected lots, occupied buildings, and residences. Property owners may petition for new road names, however, The City of Santa Fe is the final authority for all road naming.
4) Public safety and timely emergency response is the primary objective for E-911/physical address assignment. An address may be changed to correct any circumstance that may cause confusion in locating an address in the event of an emergency.
5) A change of address may be initiated by a property owner or the City GIS Staff. A city-initiated address change occurs when an address poses an emergency service response delay for the property owner or surrounding neighbors. The City GIS staff is notified of these issues by emergency service providers, property owners, and City staff.

I am not receiving mail/packages. How can I fix this?
Check with your local Post Office to determine if your address is in their database. If not, then request that your address be added. If the Post Office asks for verification, E-911 Addressing staff can provide an Address Verification Form.

Google Maps cannot find me or does not show me in the correct location. What do I do?
Contact the GIS Staff to confirm your location. If needed, staff will submit feedback to Google Maps.

Utility company (such as PNM and NM Gas Company) has a different service address than my physical address. How do I reconcile this?
Obtain an Address Verification Form from the GIS Staff and present it to the utility company’s customer service department.

MVD requires two proofs of address to obtain a driver’s license. What do I need to do?
An E-911 Address Verification Form can serve as one of the required proof of address documents.

Why would a road name change?
If the City of Santa Fe discovers a duplicate road name or the threshold of four or more lots, occupied buildings, or residences is met or exceeded, a new road name will be required. (City of Santa Fe Ordinance 1987-5 requires that any road or driveway, whether public or private, that accesses four or more lots, occupied buildings, or residences, shall be named.) Property owners may petition for new road names, however, the City of Santa Fe is the final authority for all road naming.
