City of Fernley Department of Public Works DESIGN STANDARDS 1.0 - GENERAL INFORMATION 1.1. INTRODUCTION The City of Fernley Department of Public Works hereinafter referred to as “Public Works”, will review all developments located within the City Public Works boundaries to evaluate the feasibility of integrating the development, presently or in the future, with Public Works systems. Once a project has been determined feasible, complete design and improvement plans are required for Public Works review. A copy of all Public Works Ordinances and Regulations presently in effect can be obtained from the office of Public Works. This document is meant to assist the consulting engineer with the preparation of the required design and improvement plans. It is impossible to cover all contingencies and possible situations within a single document. Conditions and situations not covered in these Standards and Guidelines shall be designed in accordance with acceptable standards for engineering practice with approval by Public Works. If there is a dispute or problems arise during any phase of a project, it is the director of Public Works responsibility to interpret Design Standards. Comments or suggested revisions to the Design Standards can be dropped off at the City of Fernley Public Works Department. The revision suggestions will be reviewed during a designated Design Standard review process. Following any Public Works policy changes, design criteria or design standard revisions, Public Works shall post at both the City Hall and the Builder’s Association at least one month prior to implementation. 1.2.
