Engineering

The Engineering Division is dedicated to giving support and guidance for the administration and construction of a high quality infrastructure that provides a safe environment while at the same time keeping a balance between the interests of the private and public sectors.

The division’s primary focus is on the engineering, coordination, and inspection of the city infrastructure and capital improvement projects for each year. Developers and citizens rely on the Engineering Division to provide information about the city utilities and street systems and to provide assistance with various permits.


Another very important activity of the Engineering Division is to work closely with ODOT District 1 in helping them with their planning needs, engineering, coordination, and inspection.


Engineering works very closely with all city divisions. The previously mentioned work could not be achieved without their help. In turn, we help them with their work as needed. This sharing of work skills, knowledge, and abilities between the various city divisions is what makes the city service divisions work so well for our citizens.

All of the projects, permits, etc., need to have a final home, so our staff also spends time updating all of the city maps and the GIS system. They are used daily throughout the city. To perform all of this work on a yearly basis requires the efforts of a very highly skilled, technical, and organized engineering staff. The staff works hard at taking a proactive, behind-the-scenes approach to project management so that the work and construction goes on as seamlessly and effortlessly as possible to those affected. We believe in continuing to make Defiance “A Great Place to Live.”

Infrastructure Management

The Engineering Division is responsible for tracking and recording all of the various city owned data as it relates to city owned infrastructure, such as streets, signage, traffic signals, water lines, storm and sanitary sewers, etc..

This database of information is being used to help plan and coordinate Capital Improvement expenditures for our annual street improvements projects, waterline replacement projects, storm and sanitary sewer improvements and other infrastructure investments.

The City of Defiance provided the public with information on pavement management at the April 10, 2018 Council Meeting.  The presentation included the City’s current approach to pavement management using street history data, asset inventory, life cycle cost considerations and evaluations of various types of maintenance techniques with associated cost.  Information relating to projected funding levels required for pavement management was also provided.  Click here for a copy of the presentation.

The current Capital Improvements Plan Map is a 10 year projection based on known needs. This map is dynamic in nature, and changes based on available and anticipated funding levels.

The current Projected Street Improvements Map  is a 5 year projection based on available and anticipated funding.

The Street Surface Age Map shows the surface pavement history on all streets city-wide.
