Public Works Engineering & Construction Standards
Design Standards Manual Preface
The City Standards for Public Works Engineering and Construction Manual has been prepared to provide a graphic and written representation of minimum standards for construction of public improvements within the public right-of-way, easements, city properties and on private property relating to utilities which are connected to the basic city utility system. The application of this manual has been coordinated with the latest edition of the Standard Specifications for Road, Bridge and Municipal Construction, published by the Washington State Department of Transportation and the American Public Works Association.
This manual was compiled by staff of both the Office of the City Engineer and Public Works Department of the City of Puyallup, representing years of field and design experience. The intent is to achieve maximum uniformity of engineering and construction practices within the City of Puyallup.
