About the Standards

The City of Hillsboro Design and Construction Standards (DCS) help to keep people and property safe by setting minimum standards for the design and construction of public infrastructure. The DCS ensure adequate quality and function of public improvements. 

While the information in the DCS is most relevant to developers and engineers, there are some sections that are applicable to home and land owners in Hillsboro. These include:  

  • Street tree and sidewalk maintenance and replacement
  • Driveway renovation
  • Drainage
  • Erosion control

The DCS also regulate the design and construction of private transportation and utility improvements which connect to or impact public infrastructure. 

The current Design and Construction Standards were adopted by Resolution 2607 on October 2, 2018.
