Characteristics of the County and the Road Network

Waukesha County is a metropolitan county with a population of nearly 390,000 persons. Over 90% of

the population is urban. Milwaukee County is to the east, Racine and Walworth counties are to the

south, Jefferson County is to the west, and Dodge and Washington counties are to the north. The

county is 581 square miles large, approximately 95% of which is land.

There are 91 lakes in the county, including Pewaukee Lake, Big Muskego Lake, Okauchee Lake, Lac La

Belle, Nagawicka Lake, Oconomowoc Lake, Pine Lake, Little Muskego Lake, North Lake, Lower Phantom

Lake, Beaver Lake, Eagle Spring Lake, Upper Nemahbin Lake, Lower Nemahbin Lake, Golden Lake, Lake

Keesus, and Silver Lake. Aside from the lakes, the most prominent topological feature is the kettle

moraine extending north-northwest through Eagle, North Prairie, Wales, between Delafield and

Pewaukee Lake, and through Merton. Kettle Moraine State Forest is along this ridge west of North

Prairie and south-southwest into Jefferson and Walworth Counties. There are also some large hills

between Waukesha, New Berlin, Muskego, and Big Bend. The lowest elevation is in Butler along the

Menomonee River and the highest elevation is Lapham Peak in the town of Delafield.

Interstate 94 is an east-west highway, carrying traffic that bypasses Summit, Oconomowoc, Delafield,

the City of Pewaukee, Waukesha, and Brookfield. To the east, I-94 heads to Milwaukee and then south

surrounded by Menomonee Falls on three sides in which there is a chocolate plant owned by Cargill

(formerly ADM). It can only be accessed via road from roads in Milwaukee.

Lannon is surrounded by Menomonee Falls on three sides with the Town of Lisbon on the other. CTH W

begins at W Main St on W Good Hope Rd in Lannon and heads east, ending at STH 175 in Menomonee

Falls. CTH F is W Main St in Lannon, and it heads west and south through the town of Lisbon, Sussex,

and the city of Pewaukee. CTH F turns south on Waukesha Ave at Main St in Sussex, becoming Redford

Blvd in the city of Pewaukee, where it first intersects STH 190 and then I-94. CTH Y is Lannon Rd in

Lannon. To the north, it travels through Menomonee Falls and heads into Germantown in Washington

County, where it is also designated as CTH Y. In Germantown, CTH Y intersects STH 175 and I-41. Across

I-41, CTH Y becomes STH 167. To the south, CTH Y heads into Menomonee Falls, but it does not connect

with the CTH Y further south in Brookfield, Waukesha, New Berlin, and Muskego. CTH V runs along the

western municipal boundary of Lannon. CTH V heads north and south of Lannon along the municipal

boundary of Menomonee Falls. To the south, CTH V intersects CTH VV and ends at CTH K. To the north,

CTH V heads to CTH Q, which is County Line Rd, a road that travels along border of Waukesha and

Washington counties.

CTH P in the town of Oconomowoc may carry a significant amount of long-distance traffic between

western portions of Waukesha County and the Fox Valley.

Municipalities

Waukesha County is the third most populous county in the state, constituting 6.85% of the state’s

population and is part of the Milwaukee-Waukesha-West Allis, WI Metropolitan Statistical Area (MSA).

The cities of Waukesha, New Berlin, Brookfield, and Muskego, plus the village of Menomonee Falls, all

have a 2015 estimated population of greater than 20,000 people, reflecting the overall suburban nature

of the county, given it is at the geographical peripheral of the MSA. But Waukesha County differs from

Washington County, which is also at the geographical peripheral of the same MSA, in that it has a level

of manufacturing comparable to Milwaukee County. Milwaukee County has 46,104 manufacturing

sector employees, whereas Waukesha County has 43,605, as of 2014. The level of manufacturing in a

county as populous as Waukesha County is significant to transportation and all of its safety-related

factors for both the businesses and the employees commuting to the businesses.

The following table includes 2015 population estimates for the municipalities within the county.1 For

municipalities in multiple counties, the table only includes the population that resides in the county.

Emergency Medical Services

Waukesha County has five trauma centers, consisting of one level II (adult only), three level III, and one

level IV centers. The level II trauma center is Aurora Medical Center –Summit in the village of Summit.

The three level III trauma centers are Community Memorial Hospital in Menomonee Falls, Wheaton

Franciscan Healthcare Elmbrook Memorial Hospital in the city of Brookfield, and Oconomowoc

Memorial Hospital in the city of Oconomowoc. The only level IV trauma center in Waukesha County is

Waukesha Memorial Hospital in the city of Waukesha.

The closest level I or level II trauma centers for adults to the city of Waukesha, the county seat and most

populated municipality, are Froedtert Memorial Lutheran Hospital in the city of Milwaukee,

approximately 13 miles away, and Aurora Medical Center in the village of Summit (within Waukesha

County), approximately 15 miles away. The closest pediatric level I or level II trauma center is Children's

Hospital of Wisconsin in the city of Milwaukee, approximately 13 miles from the city of Waukesha and is

in the same medical complex as the Froedtert Memorial adult trauma center.

8

A long distance from a level I or level II trauma center will have a negative impact on the outcomes of

motor vehicle crashes especially as the population ages. But with the nearby availability of two adult

and one pediatric trauma centers, the likelihood of healthier crash outcomes is greater for the residents

of Waukesha County than for many other counties in the state.

As of 2015, there were 1,459 emergency medical technicians (EMTs) in Waukesha County operating out

of 29 different EMS providers. The largest of these organizations are the Menomonee Falls (Village of)

Fire Department, the Waukesha (City of) Fire Department, the Oconomowoc Fire Department, and the

Dousman Fire District. A table of these organizations is below:

There are 3.70 EMTs per 1,000 persons in the county, compared to 3.85 EMTs per 1,000 persons

statewide.

Also, a number of employed persons commute between Waukesha and Washington, Racine, Jefferson,

and Walworth counties, with more workers coming to Waukesha County than workers going from

Waukesha County to these other counties. The one-way shift in employees creates a situation, where

attempting to address traffic safety issues will probably need to involve significant coordination with

these counties.
