CityofRedmond WASHINGTON STANDARD SPECIFICATIONS AND DETAILS 2013 Approved ---PAGE BREAK--- ---PAGE BREAK--- CityofRedmond WASHINGTON PREFACE The 2013 edition of the City of Redmond Standard Specifications and Details (henceforth referred to as the 2013 Standard Specifications and Details) has been prepared by the City of Redmond Public Works Department. This document supplements and in some cases supersedes the 2012 WSDOT I APWA Standard Specifications for Road, Bridge, and Municipal Construction and Amendments. For all work in the City of Redmond, the following apply on all individual projects and are considered as a whole: • The printed hard copy version of the 2013 Redmond Standard Specifications and Details • Work Zone Traffic Control Manual (used in conjunction with the MUTCD) • 2012 WSDOT Standard Specifications for Road, Bridge, and Municipal Construction and Amendments • Laws of the State of Washington • Charter and Ordinances of the City of Redmond • Project Manual and Drawings for the individual project The 2013 Standard Specifications and Details shall govern all phases of work for, but not be limited to public and private streets, driveways, parking lots, commercial and industrial developments, residential construction, within the City of Redmond limits and any City of Redmond franchised utility. All requirements of the 2013 Standard Specifications and Details apply to such work in the same manner as though the work were being performed under a contract awarded by the City of Redmond, with the exception of those requirements or conditions pertaining to payment for the work performed or to withholding or receiving money due the Contractor. All matters relating to financing of such work shall be between the permittee and the Contractor, and the City will not enter into such matters. Where the Standard Specifications refer to the Engineer, the City Inspector shall have authority to inspect and direct work for compliance with City standards. Despite considerable efforts to produce a completely error-free document, some mistakes seem to defy detection until after publication. Should you discover errors in this document, please bring them to our attention at City of Redmond, Public Works Department, PO Box 97010, MS:2NPW, Redmond, WA 98073, or by email at [EMAIL REDACTED].

Please request CD and/or hard copy 24-hours in advance for pick up at the Development Services Permit Center. My sincere thanks and appreciation go to the individuals in the City's Public Works Department who provided input, review and evaluation of this document. ---PAGE BREAK--- ---PAGE BREAK--- June 2013 TABLE OF CONTENTS Section Standard Plan Revision Date Notes Preface 6/1/13 Table of Contents 6/1/13 1 STANDARD SPECIFICATIONS 6/1/13 Section Standard Plan Revision Date City of Redmond Standard Plan WSDOT Standard Plan Notes 2 CONSTRUCTION ALONG/ACROSS CITY RIGHT-OF-WAY Typical Trench Detail 6/1/13 201 Removed overlay and replaced with add’l full depth;
