2026 Supplemental Specifications
These Specifications and Drawings are intended to supplement the current edition of the Idaho Standards for Public Works Construction (ISPWC). In instances where the ISPWC does not clearly provide for additional requirement(s) of the City of Meridian, these Specifications shall be used.
All construction within the City of Meridian, or within the jurisdiction of the City of Meridian, shall be in accordance with the ISPWC and these Supplemental Specifications and Standard Drawings; the approved Construction Plans; the City of Meridian Construction Stormwater Management Program (CSWMP) manual; all pertinent construction documents; all applicable State, Federal, County, and local district regulations and Specifications; and in compliance with the City of Meridian Subdivision Ordinance. The more stringent of any of these standards shall be the controlling standards or specifications. The City of Meridian recognizes that the ISPWC and these Supplemental Specifications may not cover all situations that might be encountered; however, this does not release the Contractor from properly constructing the work.
Any supplemental specification that the City Engineer or a designated representative deems necessary for the proper construction of any work shall be prepared and issued to the Contractor prior to commencing construction.
City Engineer's Letter
These Supplemental Specifications and Drawings were prepared for, and apply to typical Public Works Construction conditions only. The need may arise to alter them to meet a specific design condition. If this occurs, all alterations, substitutions, or variances shall be approved in writing by the City Engineer or designated representative.
In the event an error or omission is discovered in these Supplemental Specifications and Drawings, whether through an oversight or a change in technology, the finder shall notify the City Engineer in writing so that the proper steps may be taken to make corrections.
It is further understood that the City of Meridian or its authorized agents are not responsible for errors or omissions.
By: Warren Stewart, P.E. City Engineer
