19.50.010 Introduction.
A. The items herein contained are the street light standards, conditions, and specifications of the city of Rock Island, and are to be considered in conjunction with other provisions of city plans and/or regulations governing public street lights. These are minimums only and may be increased or altered to fit particular site conditions and/or situations. The city by this reference adopts the latest edition of the “Standard Specifications for Road, Bridge and Municipal Construction” (hereinafter referred to as the “Standard Specifications”) as prepared by the Washington State Department of Transportation and the Washington State Chapter of the American Public Works Association to govern all aspects of sanitary sewer system improvements including but not limited to materials, labor, equipment for installation, workmanship, testing, etc. Any material, design, standard, or testing not specifically addressed within this document shall be as per the Standard Specifications. The city also by this reference adopts the latest version of the “Standard Plans” (engineering drawings hereinafter referred to as the “Standard Plans”) published by the Washington State Department of Transportation.
B. In addition to the specific standards set forth in this chapter, the city may develop a technical specifications guidebook containing drawings that graphically depict the provisions of this chapter and the Standard Specifications. This guidebook may also specify where the city may choose to add to, remove from, and/or replace (in whole or in part) certain aspects of the Standard Specifications and Standard Plans adopted by reference herein. The guidebook is a technical reference document that may be updated periodically based on changes in engineering standards, whether those be city standards or updated standards in the design and construction documents that are adopted by reference in this chapter. (Ord. 01-062 § 5).
