County, consultant and emergency responders push to fix 170+ addressing errors for 911 reliability

Morgan County planners, emergency services and a consultant told commissioners that a countywide addressing cleanup is needed to correct roughly 170 major addressing errors that currently hinder 911 response and public services.

Nut graf: Wasatch Civil explained at the meeting how the county’s numbering system is tied to an origin point in Morgan City and the Public Land Survey System; the consultant demonstrated examples where parcel addresses “jump” hundreds of address points from one house to the next. County staff and emergency responders said those inconsistencies cause repeated 911 navigation issues and confusion for mapping services used by first responders.

What county officials heard: Thomas Good of Wasatch Civil explained the methodology used to detect and recalculate address numbers so they consistently increase away from the county “origin.” He showed several neighborhoods where current assignments reverse the expected numerical progression or have street-ring anomalies that put neighbors hundreds of address points apart. County staff explained several causes: historic ad hoc assignments, subdivision approvals that did not follow a consistent grid, and property owners requesting individual changes that later broke the grid.

Why it matters: County staff and emergency responders described examples where incorrect addresses have delayed response or created confusion for water, postal and utility providers. County GIS staff said the wrong addressing also breaks data pipelines used by dispatch apps and crowdsourced maps. One example shown in the meeting: an address listed as 3161 West sat among numbers in the 3300–3600 range, creating a nearly 400-address-point discrepancy between backyard neighbors.

Technical and data steps discussed: The county will pursue a multi-part cleanup: (1) adopt a corrected addressing grid and implement it in the county parcel fabric; (2) upload authoritative address updates to OpenStreetMap and to major map providers (Apple Maps and Google Maps) — county GIS staff described a routine of creating a bulk data package to share with mapping vendors; (3) conduct community outreach to affected property owners and coordinate with postal, water and emergency dispatch partners; (4) create internal procedures to avoid ad hoc deviations in the future.

Speakers and roles identified in the meeting: Thomas Good (Wasatch Civil, consultant), Josh (county planning staff), Charles (county GIS staff), Boyd (emergency services representative). County staff said Apple/Google updates can be requested and that OpenStreetMap is used by dispatch systems; they noted mapping vendors prioritize updates but changes are routinely accepted when submitted as a county-certified data file.

Next steps and timeline: Staff said on-site training for the county’s new parcel fabric (redrawn countywide maps) is scheduled within weeks; Charles (GIS) and planning staff will lead uploads to mapping vendors and work with affected homeowners on formal address affidavits where changes are required. Commissioners asked staff to return with an outreach plan and estimated timeline and to identify funding needs for survey, sign replacement and public notification.

Proper names in discussion: Wasatch Civil, Morgan City origin grid, OpenStreetMap, Apple Maps, Google Maps.
