Technical Standards Manual
The City Council adopted the new Garland Development Code (GDC) on Tuesday, May 19, 2015. The Engineering Department has created a Technical Standards Manual (TSM) that was adopted in conjunction with the GDC. The purpose of the manual is to ensure that all public infrastructure in the City is designed and constructed to the highest standards.
The TSM replaces the Public Works Design Guideline from 1996 and the Traffic Management Standards from 1996 in their entirety.
Current Version of the TSM
This manual may be revised periodically. The proposed revision will be posted on this website for a period of 30 days prior to implementation unless the revision is required to comply with Federal, State, County and City laws, regulations, ordinances or codes. The Appendix consists of checklists and forms pertaining to the Technical Standards Manual and therefore may be revised to correspond to the TSM or City Ordinances without a review period.
At any time, if you have a comment or request to modify current design criteria or add new design criteria, a formal request can be submitted to the City for consideration in writing to the Director of Engineering. These comments will be reviewed and responded to.
This page will contain the City’s most current version of the TSM. The Technical Standards Manual will include a Record of Revisions to identify any revisions to the Technical Standards Manual. Please send questions or comments via email at DevEngineeringGroup@garlandtx.gov
