Design Standards Manual

The Design Standards Manual is a guide for the planning, design, and construction of stormwater and sanitary sewer collection systems, water distribution systems and facilities, and associated activities for City Utilities. Guidelines, basic design criteria, standards, and mapping are presented in the Standards.

Book 1: General Requirements
Outlines City Utilities general policies for coordination, approval procedures, preparation of drawings and accompanying documents, and basic criteria associated with stormwater, sanitary sewer, and potable water improvement projects.

Book 2: Stormwater
Outlines stormwater standards and policies for the design of stormwater facilities.

Book 3: Sanitary
Outlines standards and policies for the design of sanitary sewers and sanitary lift stations.

Book 4: Water
Outlines standards and policies for the design of potable water distribution systems.

Book 5: Materials
Outlines approved construction materials used on stormwater, sanitary, or water projects.

Book 6: CADD Standards
Outlines drawing requirements and details for use on stormwater, sanitary sewer and water projects.

The final version of the Design Standards Manual is being completed and will soon be posted in its entirety. The chapters that are currently posted have been revised and the final, approved versions are found below.
