Shift points for central operations are coded A1-A99, these are usually 
either an intersection, or a specific location such as a gas station 
for fueling. Ambulances are positioned strategically throughout the 
counties to provide coverage. A unit is typically required to be within 
500 meters of the particular point they are stationed. Each crew, typically
has a particular spot they like to park when sitting at a point, such 
as in an empty parking lot or behind buildings.

Huron Valley Ambulance (HVA) Unit Numbering

Washtenaw (Central Operations), Western Wayne, & Oakland (Eastern Operations) Counties:

C100 – Vice President of Central operations

Day Cars - mostly 12 & 10 hour units.  These units range from A101-A113, and 
any extra cars added, start with A114 to A119. They are posted as specific
shift points and are moved when coverage changes:

A101 is the first car to come on in the morning at 04:30 hours.
A113 the last of the day cars starts at 14:00 hours.

The night cars start with A130 – 133 with extra cars starting at A134 to A139.

A150 is the day Mobile Intensive Care Unit (MICU).

A151 is the night MICU.

These units sit shift point and pull calls the same as all 
other Alpha cars however, they do not do P4-5 unless it is a MICU 
call that requires further treatment and equipment than normal ALS 
cars can handle.

A158 = Neonatal Intensive Care Unit (NICU) Also referred to as 
the baby bus:

This unit is a larger type III, medium duty ambulance, used to transport 
neonates requiring extra equipment. In addition, adult (obese) patients
requiring larger equipment such as ECMO that will not fit in 
a normal modular ambulance. This unit usually has staff from 
the hospital on board such as RN’s & MD’s.

sit at such events as U of M baseball games and other community events.

E170 = Dexter Echo unit.

B180 to B188 are BLS units usually reserved for non-emergent P4s & P5s 
(hospital to nursing home, nursing home to doc appointment, Ect…) 
These units typical do not respond to 911 calls unless the ALS unit 
is more than 10min from the call.
