Design Criteria and Engineering Standards

Contact

 

The Town of Whitby has developed engineering design criteria and engineering standards as guidance for consulting engineers on design issues under the jurisdiction of the Public Works Department. This includes storm drainage, Town of Whitby roads, lot grading, fencing, and street lighting, among others. 

Separate design criteria and guidelines that may apply to a particular project are available from: Regional Municipality of Durham (Sanitary Sewer, Watermains and Regional Roads), Whitby Hydro (Electrical Distribution) Town of Whitby Planning Department, Region of Durham Planning Department, CLOCA/MNR (Watercourses and Environmentally Sensitive Areas), MTO (Provincial Highways), Railroads and other authorities when required.

The engineering design criteria make reference to the Town of Whitby Standard Drawings found in the Engineering Design Standards, which provide details on certain areas to clarify the design intent. These Engineering Design Standards are indexed as follows:

  • Section 100 - Storm Sewers
  • Section 200 - Curbs/Sidewalks
  • Section 300 - Grading
  • Section 400 - Geometrics
  • Section 500 - Miscellaneous
