Delaware County Engineer 



The County Engineer's administrative staff includes the Chief Deputy Engineer, Information Systems staff, Safety Officer, Accounting staff and administrative assistants.  The Administration manages the operation of the office and oversees the duties performed by the other departments.


Construction Department:

The construction department staff performs construction management and inspection of county construction projects of roads, bridges and sewers on capital improvements projects.  The department also performs inspection of privately funded subdivision and commercial projects.


Design Department:

The design department plans, programs, budgets, designs and manages publicly funded projects.  The department's staff of seven includes professional engineers, graduate engineers, surveyors and technicians.  The group members assist with the inventory, and inspection of the county's bridges as well as traffic related duties such as speed limit studies and traffic signal warrants.  They work closely with the Development Review staff for coordination of public and privately funded projects as well as the Inspection staff in the supervision of roadway construction projects.  The design department also works with other agencies such as the Ohio Department of Transportation to deliver roadway projects that improve safety and mobility for citizens of Delaware County.


Development Review:

The development review department's staff of three professional engineers and technicians review plans for proposed residential, commercial and industrial developments in unincorporated areas of Delaware County.  The purpose of this review is to ensure that new developments meet all necessary requirements to ensure the public's safety and welfare, such as roadway, storm sewer and traffic control design.



The operations division (also known as the Highway Department) is the largest section of the Engineer's Office and employs a number of crews consisting of operating engineers, skilled laborers, drivers and mechanics.  The Highway Department maintains county highways by repairing or resurfacing pavements and berms, mowing roadsides, installing traffic signs, maintaining traffic signals, and constructing culverts and small bridges.  In winter months, the snow fighters plow and salt roads to keep traffic moving safely.


Map Department:

The map department has a number of responsibilities relating to the County Engineer's mapping and surveying duties. The department's staff of four maintains the official county tax maps in cooperation with the County Auditor's Delaware Area Land Information System (DALIS) staff.  The map department also reviews all surveys and legal descriptions for property transfers in Delaware County to ensure that they meet legal requirements.  The staff also serves customers who need specific mapping information for areas of the county by providing detailed maps upon request.


Permit Department:

The permit and utility coordination staff oversees work within the right-of-way by public utilities and property owners.  This ensures that all utility work, including relocation of overhead and buried electric, phone, cable, water and gas lines does not interfere with the safety and operation of the county road.  Also, any work done by a resident to the front of their property (inside the road right-of-way), including construction of new driveways, installation of drainage pipes, regrading ditches or installing obstructions that would otherwise affect the operation or safety of the road must be reviewed by the permit department.


Stormwater Department:

The stormwater staff is responsible for administration of the Phase II National Pollution Discharge Elimination System (NPDES) Storm Water Program.  The staff inspects the drainage and erosion control on construction projects in Delaware County to ensure that surface waters are not contaminated by sediment and runoff from construction sites.  The drainage administrator coordinates waterway and stormwater permits for the construction activity done by other sections of the office, and also works closely with the Delaware Soil and Water Conservation District on drainage projects such as ditch and farm tile construction.
