CITY OF ENCINITAS ENGINEERING DESIGN MANUAL - 2009
INTRODUCTION
The City of Encinitas Engineering Department has authored this Engineering
Design Manual to assist the professional design community and the general
public by consolidating information concerning the City's engineering
standards and submittal requirements for various plans and permits
administered by the Engineering Department. The manual is intended to be
used as a guideline for design, plan preparation, and permit processing, and
it includes the following chapters:
Chapter 1: Map/ Parcel Map Preparation and Processing Requirements
Chapter 2: Permits and Processing
Chapter 3: Grading Plan Preparation and Submittal Requirements
Chapter 4: Sewer Design Requirements
Chapter 5: Water Design Requirements
Chapter 6: Drainage Design Requirements
Chapter 1 covers all City requirements pertaining to maps and City map
review. Chapter 2, Permits and Processing, describes all permits issued by
the City Engineering Department and outlines requirements specific to each.
Chapter 3, Grading Plan Preparation and Submittal Requirements, covers in
depth the standards for grading plans, but it can also be used as a general
guide for the preparation of improvement plans; for instance, the standard
notes required for improvement plan title sheets are presented here.
Specific requirements for improvement plans relating to sewer, water,
drainage design, and street design are discussed in Chapters 4, 5, 6, and 8,
respectively. Permanent storm water pollution control BMPs required for
most grading and improvement projects are discussed in Chapter 7.
The Engineering Design Manual contains appendices specific to the material
presented in each of the chapters. These appendices are designed to be
modified and updated as City requirements change from time to time. If in
doubt, please contact the City Engineering Department or reference the
posting of the Engineering Design Manual on the City website to ensure that
a current version is being used.
Should you have any questions, please contact the Engineering Department
at (760) 633 -2770.
