To minimize the spread of COVID-19, the City will be reducing service levels to essential services only. All City Hall offices are closed, except Development Services  and the Permit Counter (temporarily on the first floor) which is open Monday-Friday from 9AM-3PM. See the Essential Services guide under the News Section for more details.

Engineering Department



Vision Statement

Counter Hours: 8:00am - 4:00pm, Monday - Friday


The Engineering Department is focused on project and program support of activities that are primarily in the public right-of-way or are associated with public facilities.  These activities involving public facilities and infrastructure may include but are not limited to: roads, streets, bridges, utilities (i.e. water, sewer, reclaimed water,and stormwater), waterways, parks, City buildings and other facilities.  The Engineering staff manages and executes capital improvement projects that are approved within the City’s budget.  Capital improvement projects enhance public safety, improve quality of life, and expand economic development.  Recently the Engineering Department has been focused on developing a programmatic approach to replacing the City’s water distribution system, sewer collection system, and the rehabilitation of City streets.  

Inspection Services
The Construction Management Division inspects the installation of infrastructure for development projects and oversees any work that is performed within the public right-of-way for both capital improvement projects and work being performed by private developers or by utility companies.

In 2017, the City added a GIS analyst to the Engineering team to resurrect the digital data transfer that was started in 2008.  This quickly proved to be an invaluable asset to the decision making process for repairs/replacements of existing infrastructure and the mapping of City owned and maintained infrastructure.
