EMS Response

REMSA Health Response Zone Map

REMSA Health, a non-profit private ambulance company, provides ground ambulance transport for City of Sparks, City of Reno, and the Truckee Meadows Fire Protection District service areas. This map illustrates the designated response expectations for presumptively defined life-threatening calls (Priority 1 calls) within those service areas. This is also known as the REMSA Health Franchise Response Zones. Each zone (A–E) corresponds to a different time for expected response. These response times are as follows:

• Zone A – eight (8) minutes and fifty-nine (59) seconds or less
• Zone B – fifteen (15) minutes and fifty-nine (59) seconds or less
• Zone C – twenty (20) minutes and fifty-nine (59) seconds or less
• Zone D – thirty (30) minutes and fifty-nine (59) seconds or less
• Zone E – as quickly as possible

The REMSA Health Response Zone Map is reviewed annually, with changes made as needed based on population growth and population density. The review process includes both annual reviews and census year reviews. View the most recent annual review summary. 

The map is created by the Emergency Medical Services (EMS) Oversight Program and Washoe County Regional Services Geographic Information Systems. It is reviewed by the EMS Oversight Program and REMSA Health, and approved by the District Board of Health.

The last revision to the map was effective July 1, 2024. There were no revisions in 2025 or 2026; however, a new format was created in 2025 to improve accessibility.
