Resolutions-1997-021

1 - GENERAL 1.01 ABOUT THESE STANDARDS These Design Standards are based on a standard developed by a team of private and public sector engineers for use in the design of most common public improvements, most development activities and utility work within the public right-of-way. The intent of the joint effort was to set a standard of design for the Metropolitan Area that is consistent, effective, efficient and protects public safety. The standards in this document have been modified to meet the needs of the City of Tiffin, Iowa. 1.02 HOW TO USE THESE STANDARDS The standards contained in this document are organized into sections covering specific areas of design. It will often be necessary to use a number of sections for the design of a single project. For instance, the design of a street may require the use of standards on streets, sidewalks, storm sewers, traffic control signals and erosion control. These standards are a guide for design, but not a substitute for good engineering. It is the obligation of the designer to use these standards responsibly and professionally to produce designs conforming with commonly accepted engineering practices and the Code of Professional Conduct. It will at times be desirable and/or necessary to vary from the standards in this document to produce a good product. When the need arises, please refer to the following section on variances. It should also be noted that while one of the goals of this document was to develop uniform design standards for the metropolitan area, some standards continue to vary from community to community. 1.03 VARIANCES When it becomes necessary or desirable to vary from the standards presented in this document, a variance may be requested by the Engineer of Record to the City of Tiffin. Such a request shall be made in writing and will include: 1. The standard to be varied. 2. The proposed variation. 3. Justification for the variance. A written response will be given within thirty (30) business days of the request. 1.04 AMENDMENTS Amendments to these standards may be requested by writing to the City Engineer with details and justification for an amendment. The City Engineer representing the City will meet periodically to discuss proposed amendments and make recommendations to the City Council.
