FROM: PUBLIC WORKS DEPARTMENT/ENGINEERING DIVISION
SUBJECT: APPROVAL OF THE ORANGE COUNTY STORM WATER PROGRAM
DRAINAGE AREA MANAGEMENT PLAN (DAMP) AND THE CITY'S LOCAL
IMPLEMENTATION PLAN (LIP)
SUMMARY
The Orange County Storm Water Program 2003 Drainage Area Management Plan (DAMP) provides
the guidelines for compliance with the Santa Ana Region National Pollutant Discharge Elimination
System (NPDES) Storm Water Permit. The City's Local Implementation Plan (LIP) is a management
document that summarizes the City's activities to meet the requirements of the Santa Ana Region
NPDES Storm Water Permit. The City's principal enforcement tools to ensure compliance with the
requirements of the NPDES Permit are its Water Quality Ordinance (WQO), Grading Ordinance,
other relevant existing ordinances, and the DAMP. The 2003 DAMP and the City's LIP were
developed in cooperation with the Orange County Storm Water Program Staff. These documents are
now complete and are ready for approval by the City Council. The storm water program is dynamic,
and as new technology or information becomes available, the City is required to update its program.
RECOMMENDATION
It is recommended that the City Council approve the Orange County Storm Water Program 2003
Drainage Area Management Plan (DAMP) and the City's Local Implementation Plan (LIP).
FISCAL IMPACT
The City's Fiscal Year 2003/2004 NPDES Operating Budget (01-402-6222) currently provides funding
in the amount of $260,000 for implementation of current year LIP programs, including various
structural and non-structural Best Management Practices (BMPs). Approximately 50% of the City's
NPDES Operating Budget also funds a prorated share of the Orange County Storm Water Program
since the County is providing programs for permit compliance at a regional level. Annual staff time
expended as a result of the current NPDES Permit requirements is estimated at $240,000. This effort
includes both program development and implementation activities provided by the Public Works and
Community Development Departments. The total annual fiscal impact due to permit compliance with
the Santa Ana Region NPDES Permit, including both staff time and operating budget activities, is
approximately $500,000. Since the term of the Santa Ana Region NPDES Storm Water Permit ends
in Fiscal Year 2006/2007, subsequent program development and implementation activities will be
budgeted in the NPDES Operating Budget for the upcoming years.

BACKGROUND AND DISCUSSION
The 2003 DAMP and existing City ordinances, as they may be modified, are intended to serve as the
basis for City compliance with the Santa Ana Region NPDES Storm Water Permit. The LIP is a
management tool that summarizes City Activities required by the NPDES Permit and their
conformance with the DAMP (Executive Summaries are attached). These documents identify various
BMPs and control techniques which may be implemented and reported to the Regional Board. In
developing the LIP, the City has utilized the 2003 DAMP and its ordinances as the foundation for its
program development. The LIP describes the distinct elements of the City's Management Program
for compliance with the permit, such as its legal authority, municipal activities, public education, new
development, significant redevelopment, construction, existing development, illicit connections/illegal
discharges, water quality monitoring, and watersheds. The program includes monitoring of program
activities in an effort to measure water quality improvements.
A Negative Declaration was prepared and approved by the County pursuant to California
Environmental Quality Act (CEQA) for the DAMP. The County of Orange, as "lead agency", prepared
the document and the City of Tustin was listed as a Responsible Agency. Upon completion of the
document, the County determined that implementation of the 2003 DAMP would create no significant
environmental impacts requiring mitigation.
Amendments to the City's Water Quality Ordinance, Chapter 9 of A~ticle 4 of the Tustin City Code,
and the City's Grading Ordinance, Chapter 9 of Article 8 of the Tustin City Code, will be introduced
and have first reading at the November 3, 2003, City Council Meeting to bring these ordinances into
compliance with the current requirements of the NPDES Municipal Storm Water Permit as issued by
the California Regional Water Quality Control Board, Order No. R8-2002-0010, NPDES No.
CAS618030. The proposed amendments to the WQO involve refinement to the roles of staff
regarding administrative orders and the addition of criminal enforcement authority by the City. The
proposed amendments to the Grading Ordinance involve a refined definition of grading activities and
minor modifications to allow conformance with Orange County's model grading ordinance.
Copies of the 2003 Orange County Drainage Area Management Plan and the City of Tustin's Local
Implementation Plan are available at the City's Public Works Department.

LIP Executive Summary
EXECUTIVE SUMMARY
This document details the Drainage Area Management Plan (DAMP) to be implemented
by the County of Orange, Orange County Flood Control District and incorporated cities
(Permittees). The 1993 DAMP was updated in order to reflect the current status of the
NPDES Stormwater Program within Orange Cotmty as well as to provide the future
direction to the program for the Third Term Permit (2002-2007).
Since the DAMP is the result of a comprehensive planning process it will continue to
undergo revision as new information, particularly water quality data, becomes available.
Through this DAMP, the Permittees intend to continue to improve existing stormwater
quality management practices and, where necessary, to address identified problems and
to implement new practices.
The DAMP revision has been formulated with the following objectives in mind:
Address the requirements of the Third Term Permits;
· Ensure effective public participation and support;
· Focus on problems identified through monitoring;
· Utilize available resources effectively;
· Implement public education as a central program component;
· Detect and eliminate illicit connections/illegal discharges;
· Evaluate opportunities and implement projects for retrofitting existing structures as
identified through the watershed planning process;
· Verify Best Management Practice (BMPs) designs and effectiveness through
experience, research and demonstration projects; and
· Develop plans on a watershed basis.
Private and public sector representatives participated in developing the stormwater
pollutant control programs described within this DAMP. Throughout the DAMP's
evolution, the document will be available for public review and comment. Overall
program guidance will be provided by the Permittees.

EXECUTIVE SUMMARY
The Draft 2003 DAMP/LIPs were completed to incorporate the programs developed since
1993, comply with the Third Term NPDES Permits and provide a programmatic foundation
for future activities. The plans propose a wide range of continuing and enhanced Best
Management Practices (BMPs) and control techniques, which will be implemented and
reported on as part of the Third Term Permit reports.
The City of Tustin has developed a LIP which provides a written account of the activities
that the City has undertaken and the City is undertaking to meet the requirements of the
Third Term Permit and make a meaningful improvement in urban water quality. In
developing this LIP, the City has utilized the 2003 DAMP as the foundation for its program
development and the LIP, as a result, contains numerous references to it and the two, in
effect, act as companion parts of the City's compliance program. The LIP is intended to
serve as the basis for City compliance during the five-year life of the Third Term Permit, but
is subject to updating and modification as the City determines necessary, or as directed by
the Regional Board.
The LIP consists of twelve (12) distinct program elements which are summarized in the
following sections. Each program element includes a focus on pollution prevention
measures as well as program effectiveness assessment.
o Introduction (Section A-l)
This element provides some initial background on the program and then describes
the City's environmental setting such as geography and climate, watersheds,
impaired waterbodies and environmentally sensitive areas, as well as the overall
organization of the LIP.
o Program Management (Section A-2)
This element describes the framework for the program management activities
including the countywide and local coordination as well as the fiscal analysis for the
