Engineering

The City of Bay City Engineering Services provides support to contractors, utilities, other units of governments, developers, businesses and residents for their development projects. Other responsibilities include:

  • Managing the City’s street and sidewalk development program
  • Assisting with the coordination of water and sewer improvements
  • Overseeing construction activities performed by the City's contractors
  • Coordinating projects with public utilities, the Michigan Department of Transportation and other agencies
  • Assisting the public regarding public utility locations, encroachment permits, sidewalk issues, etc.

Duties & Activities


Engineering Services staff administers state and federal highway grants and participates in regional transportation planning, asset management and funding efforts through the Bay City Area Transportation Study (BCATS). Daily activities include evaluating the street and sidewalk system to determine repair and maintenance needs, collecting infrastructure and traffic count data, creating and maintaining GIS maps and databases associated with Engineering Services, and administering the city's right-of-way, stormwater management and encroachment permit processes.

Transportation Asset Management Plan

As required by PA 325 of 2018, the City has developed a Transportation Asset Management Plan.  The goal is the create a strategy to manage the condition of the City's street system with the funding available.  The steps are:

  • Evaluate the overall condition of the City's road system
  • Analyze the road segments by applying multiple solutions to optimize life span of each
  • Evaluate various levels of investment required to maintain and improve overall condition
  • Establish a strategy and prioritize roadway improvements for short and long term Capital Improvement Plans

Downtown Traffic Study

A traffic study that was conducted in 2012 determined the traffic signals Downtown were not warranted.  This year, an updated study was conducted and investigated data in more detail. The 2021 report studied traffic volumes, traffic signal warrants, crash history, pedestrian timing and safety, sight distance, and parking.

The Manual for Traffic Control Devices (MUTCD) is the law governing all traffic control devices, and is used all over the country.  In this manual, there are nine warrants that are evaluated.  They consist of traffic volumes, crashes, pedestrian volume, and other factors.  If even one warrant is met, a traffic signal is considered warranted and likely the best fit for the intersection.  None of the intersections that were studied Downtown met any warrants and therefore do not meet the legal requirements for a signal.  The new study also considered other factors, and still no warrants were met. If a signal is not warranted, the risk of some types of crashes increases.

The solution to the unwarranted signals is to replace them with 2- and 4-way stops. This will increase safety and meet the legal requirements for traffic control at the intersections.

How do we select Street Projects?

We consider many things when we choose projects.  Some of them are:

  • Pavement Condition
  • Funding
  • Project Cost
  • Utility Coordination
  • Availability of Additional Funding
