Public Education Component
SECTION A-6, PUBLIC EDUCATION
City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) A-6-1
A-6.0 PUBLIC EDUCATION
A-6.1 Introduction
Public education is an essential part of the City of Yorba Linda’s municipal storm water program. Developing programs to inform and involve the public can be an effective method for controlling urban runoff and stormwater pollution. Emphasizing the relevant impacts of urban runoff and storm water pollution to each particular target audience increases the likelihood that the messages will be noticed and that the audience will support and participate in the program implementation.
The City recognizes that when a community has a clear idea of where the pollution comes from, how it directly affects them and what they can do to prevent those effects, the community will be more willing to support and participate in the pollution prevention program. The City also recognizes that the Fourth Term Permits set a higher expectation for the performance of an effective public education component of the stormwater program by setting the following goals:
• Target 100% of the residents, including businesses, commercial and industrial establishments. Through the use of the local print, radio and television, the Permittees must ensure that the public and business education program makes a minimum of 10 million impressions per year and that those impressions measurably increase the knowledge and measurably change the behavior of the targeted groups.
A-6.2 Countywide Public Education Program
The City has, and continues to support, a strong countywide public education program as described in the 2003 DAMP (see 2003 DAMP, Section 6). This program provides the common message and theme for the overall program, coordinates that message with neighboring counties to ensure that media overflow messages are compatible and provides combined media buying power that could not be achieved by this City and the other Permittees individually.
The countywide program is currently undertaking the following types of public education activities:
• Revising existing materials and developing new materials as necessary to communicate with audiences about urban runoff, how their actions affect water quality and BMPs to help solve the problem.
• Placing advertisements in local publications, on bus backs, on municipal vehicles, in theaters and/or on television and radio.
• Submitting information for city newsletters and websites. • Implementing Point-of-Purchase campaigns with stores such as home improvement and pet stores.
SECTION A-6, PUBLIC EDUCATION
City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) A-6-2
• Building relationships with community organizations and chambers of commerce. • Using utility bill inserts to communicate with residents and businesses. • Employing targeted outreach to specific industries, especially the food service industry. • Reviewing school education opportunities including Project Wet Workshops (teacher training workshops) that are endorsed by the State Water Resources Quality Board and the new Unified Environmental Education Program of CAL EPA that will focus on waste reduction and on-campus storm water activities.
To date the countywide program has resulted in the following products and accomplishments:
1. Collective preparation and distribution of hundreds of thousands of brochures, magnets, flyers and/or bookmarks. The current materials are listed below and are also included in DAMP Appendix B, Section B-6:
• “The Ocean Begins at Your Front Door” Brochure

2. The Principal Permittee provides materials, Enviroscape displays and banners for the City to use at local events.
3. Coordinating with the American Oceans Campaign storm water resources web page at www.americanoceans.org/runoff/epa.htm.
4. Publicizing the countywide 24-hour water pollution reporting hotline number (714) 567- 6363, which handles water pollution complaints as well as inquiries about storm water and public education materials. The hotline is staffed after normal business hours, on weekends and holidays by a live bilingual operator (Spanish and English).
5. Providing model storm water website materials which have been loaded on the County website, www.ocwatersheds.com and are available to the City and other Permittees. The materials include a site map and nine composed web pages with assembled photomontages, site buttons, navigation buttons and copy text. The nine pages comprise a home page, general information, pollution prevention for residents, pollution prevention for businesses, household hazardous waste and oil recycling, pollution reporting, educational materials, kid’s corner and links.
6. Development of a model watershed specific public education program to increase public awareness about the concept of watersheds, specific pollutants of concern (primarily bacteria and toxicity caused by pesticides), their sources and the solutions.
7. Development of pollutant specific education materials including a pet care activities brochure, a horse and livestock activities brochure, a car wash fundraiser brochure, a sewage spill reference guide.
8. Development of business specific education materials including BMP posters for the automotive repair industry, gasoline stations, and the food/restaurant industry; and brochures for general business practices, carpet cleaning, landscaping and gardening, and concrete and mortar work. As part of the new food facility inspection program (see 2003 DAMP, Section 9) the following information will be incorporated into revised materials and will distributed as part of a focus on almost 9500 of these facilities countywide:
• Appropriate cleaning of dumpster and grease bin areas; • Replacement of leaking or dirty dumpsters;
• Reducing liquid waste in trash and double bagging trash to prevent leaks; • Encouraging dry sweeping;
• Using covers and berms to prevent wash water from entering the storm drain system;
• Disposing of wash water to the sanitary sewer rather than the storm drain system;
SECTION A-6, PUBLIC EDUCATION
City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) A-6-4
• Stopping spills at their source; and
• Proper maintenance of outdoor grease interceptors
9. Conducting public opinion surveys in an effort to better understand the public’s awareness regarding water quality issues. The surveys conducted include:
• The 1994 Stormwater Pollution Prevention and Flood Awareness Survey by the University of California at Irvine (UCI);
• An informal survey at the 2000 Orange County Fair;
• An informal survey through the Los Angeles Times In Education Program of secondary school students on pesticide/herbicide issues; and • The 2001 Orange County Public Awareness Survey.
The primary objectives of the latter survey were 1) to provide a baseline measure of residents’ awareness, attitudes, practices and habits related to storm water pollution, against which future outreach efforts can be measured, and 2) to provide an additional program development tool, for identifying target audiences and key messages, developing strategies and confirming underlying assumptions.
10. Coordinating with other statewide, regional and Orange County public education groups and programs related to surface water quality including the California Stormwater Quality Association Public Information/Public Participation SubCommittee, the Orange County Health Care Agency’s hazardous waste reduction, food protection and animal services programs, the Orange County Integrated Waste Management Department’s household hazardous waste program and the County of Orange Public Library Department.
A-6.3 Public Education Focus
The City’s public education focus is intended to support the countywide effort through financial contributions, participation in the Public Education Committee and the use of countywide materials, thematic messages and common look. The City also intends to supplement the countywide campaign at a local level to address City specific issues and target constituencies that are best reached through a local rather than a countywide effort.
The City intends to do this through the following actions:
1. Public Education Material Distribution
The City will make educational materials available to its residents at the following public facilities:
Public Facility Materials Available

2. Employee Training and Outreach
The City will provide and/or encourage educational activities and training for its direct employees. The City employs individuals with a wide range of education, job responsibilities and skills that, through their direct actions or interface with the public, have an affect on water quality. Some of these include: planning and zoning officials, plan reviewers, emergency crews (police, fire and public works), construction site inspectors, field crews, maintenance crews, elected officials, janitorial staff, etc.
There are also a variety of City facilities and activities that can have an adverse impact on water quality. Examples include everything from large, impervious parking areas, to City vehicle repair garages or maintenance crew base stations. Due to the diversity of the target audiences and the potential impacts, the Principal Permittee is taking the lead in coordinating, developing and presenting a number of different training modules (DAMP Appendix B). The City will support this effort by requiring the appropriate
SECTION A-6, PUBLIC EDUCATION
City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) A-6-6
employees to attend the training sessions and then conducting any supporting train-thetrainer efforts that may be necessary. These local efforts will assist in reinforcing the key messages.
In addition to the overall comprehensive training effort, the City will conduct broad educational outreach on water quality issues to all its employees. The following approaches have been identified:
• Conducting meetings with employees to inform them of water quality issues and the City’s responsibilities (do’s and don’ts).
• Placing information on the City’s Storm Water Quality web page. • Routing relevant newspaper and magazine articles to specific departments or personnel.
3. Outreach to Construction Site Contractors/Developers Mismanagement of construction projects can have severe impacts on water quality if issues such as runoff, sediment control and waste materials are not properly controlled.
The City, through its permitting process, has the opportunity to target the following entities involved in the construction process:
• Builders
• Developers
• Contractors
• Property owners
The following approaches have been identified:
• Distributing BMP materials, available from the County, at construction sites within the City;
• Sending a letter to construction sites with grading permits prior to each rainy season re-emphasizing how runoff is created and reminding the operators to update their BMPs;
• Maintaining a supply of information materials at the City kiosk for interested parties to obtain during business hours throughout the year; and • Sending out notification letters to construction sites that are between 1 acre and 5 acres reminding them of their need to file for General Construction Permit coverage.
4. Outreach to Industrial Site Owners and Operators
The chemicals and materials used at industrial sites, and the wastes produced by them, can cause water quality impacts if not handled properly. The City has opportunities to supplement the countywide effort through its activities of inspecting these facilities.
Educating industrial owners and operators about BMPs will help to change behaviors at these sites.
SECTION A-6, PUBLIC EDUCATION
City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) A-6-7
Target audiences for industrial outreach include:
• Specific industrial facilities;
• Employees as well as supervisors;
• Trade associations; and
• Property management
The following approaches have been identified:
• Distributing BMP information and educating owners and operators during inspections or other interactions with City staff.
• Providing information when industrial companies apply for and/or renew business licenses or permits.
• Attending and promoting seminars or workshops for targeted industries that have a high potential for pollution. The workshops would cover BMPs for pollution prevention and how their actions can help protect water quality.
5. Outreach to Commercial Site Owners and Operators
Like industrial sites, commercial sites can produce large amounts of runoff containing pollutants. Without proper management, water quality impacts can occur. The City has opportunities to supplement the countywide effort through its activities of inspecting these facilities. Educating commercial site owners and operators about BMPs will help to change behaviors at these sites.
Target audiences for commercial outreach include:
• Employees and supervisors;
• Trade associations;
• Merchant associations;
• Franchise chain owners; and
• Property management
The following approaches have been identified:
• Providing information about BMPs and regulations when commercial owners apply for or renew business licenses or permits.
• Distributing information and educating owners and operators during inspections or other interactions with City staff.
• Attending and promoting seminars or workshops for targeted commercial sites that have a high potential for pollution. The workshops would cover BMPs for pollution prevention and how their actions can help protect water quality.
SECTION A-6, PUBLIC EDUCATION
City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) A-6-8
6. Outreach to Residential Community, General Public, and School Children Educating the general public and school children is key to a successful outreach plan.
The City has opportunities to supplement the countywide effort through its daily interactions with its citizenry.
Residents engage in numerous activities that can affect storm water quality, including washing cars, disposing of pet waste, handling hazardous substances and maintaining their lawns. Educating children and adults about these matters can have a tremendous impact on changing behaviors. It is very important that people understand not just what to do or what not to do, but why it is important. When people understand the impact of their actions, they will be more likely to change. Because members of the general public are also the same people who own, work at or patronize commercial or industrial sites, the heightened awareness gained through general public outreach will also assist in those other areas.
Reaching school children is important for two reasons. First, it educates the next generation of adults at an early age and increases the likelihood that they will engage in responsible behavior in the future. Secondly, children are able to influence their parents by asking for assistance with storm water projects for school, sharing brochures or repeating information they have learned.
The following approaches have been identified for the general population:
• Maintaining a supply of brochures and promotional materials at public buildings including City Hall, libraries and community centers.
• Participating in community events by hosting a booth with information and promotional materials.
• Stenciling storm drains to remind residents that materials entering the storm drain wind up in the ocean.
• Working with other jurisdictions, including the Principal Permittee and other Permittees, on joint outreach programs.
• Sharing and utilizing the countywide materials and those developed by other jurisdictions, and maintaining a common theme among all materials used and produced by the City.
The following approaches have been identified for school children:
• Offering child-friendly brochures, coloring books or promotional materials to schools and school districts within the City.
• Offering to provide speakers or educational materials such as video clips for assemblies.
• Participating in the countywide program to develop a comprehensive school program in conjunction with the Principal Permittee and other Permittees, water agencies and school districts.
SECTION A-6, PUBLIC EDUCATION
City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) A-6-9
7. Outreach to Quasi-Governmental Agencies/Districts
The City has opportunities to supplement the countywide effort through its daily interactions with entities that do not directly fall under its auspices. The City will work on its own and/or in conjunction with the Principal Permittee and other Permittees to reach agencies including:
• Water districts;
• School districts;
• Transportation agencies;
• Utility districts;
• Fire and police department; and
• Service providers, including waste haulers
The following approaches have been identified for these quasi-governmental agencies/districts:
• Educating personnel during inspections or other interaction with municipal personnel.
A-6.4 Public Participation
Public participation allows the public to be directly involved with the stormwater program. The City has opportunities to supplement the countywide effort by encouraging and supporting public participation at a local level.
In addition to the positive results of people changing their behaviors to reduce urban runoff and stormwater pollution, public involvement benefits the education program in several ways.
Many of the public participation elements involve direct interaction with City staff that is knowledgeable about water quality issues. People are able to ask questions and receive immediate answers. Extra time can be taken to explain issues in more depth. The City can learn what topics people have the most interest in, what approaches work best, and what approaches might not be effective, helping the County fine-tune countywide educational efforts. Also, direct interaction can make people excited and confident about information they have learned, and they will be more likely to share that information with their family, neighbors, friends and co-workers.
The following approaches have been identified to enhance public participation:
• Daily Activities
Through the public education program, residents will be asked to make adjustments to their activities to reduce the impact to the storm drains and water quality. Issues to be addressed include washing cars, cleaning oil leaks, disposing of waste and pet care. By following guidelines, the public will be helping to solve the problems caused by the improper management of common house and work activities.

By sponsoring or staffing tables at community events, the City can directly communicate with residents about important water quality issues. The one-on-one contact will allow the City to address specific questions and issues an individual might have. • School Programs
The City will be available to provide or assist in school assemblies. Interacting with children allows the City to understand the unique perspectives children have and will help us target messages that they can understand and share with their classmates and families.
• Hotline
The City will maintain a hotline residents can use to ask questions, give comments and report pollution problems (714) 961-7133. In addition, the educational materials and website will include the Principal Permittee’s pollution hotline.
A-6.5 Program Effectiveness Assessment
Section A-6.1 identified specific goals for increasing knowledge and changing potentially polluting behaviors by implementing a comprehensive public and business education program.
Information on program effectiveness will be tracked by the number of impressions recorded (See DAMP Appendix C, Section C-6) and, on a longer term, by the changes in attitudes during public awareness surveys.

2A-7.0 NEW DEVELOPMENT / REDEVELOPMENT
A-7.1 Introduction
One of the most important responsibilities of the City of Yorba Linda is to provide a decision making and approval processing framework for new development and redevelopment that occurs within the City’s boundaries. This ensures that both development and redevelopment occur in an organized and orderly fashion that reflects the vision and needs of the community, assesses the environmental issues associated with the proposed changes and provides a regulatory framework to ensure that standards set by the City are implemented.
In May 1997, the City certified to the Santa Ana Regional Board that it was implementing the new development and redevelopment water quality requirements developed with the Principal Permittee and other Permittees as Appendix G of the 1993 DAMP. Since that time, all development and redevelopment in the City has occurred in conformance with Appendix G resulting in BMPs being implemented for water quality improvement in numerous projects throughout the city.
The Fourth Term Permits require the City and other Permittees to initiate a comprehensive assessment of their planning and development processes with the intent of providing a greater focus on the protection of water bodies and a more rigorous application of BMPs in development and redevelopment projects. The City has supported the Principal Permittee in developing a model program to guide compliance with these requirements (see DAMP, Section 7).
The model program links new development BMP design, construction and operation to the earlier phases of new development project planning encompassed by the General Plan, environmental review process and development permit approval processes. The General Plan specifies policies that guide new development. The environmental review process examines impacts from proposed new development with respect to the General Plan policies and many environmental issues, including water quality, and includes consideration of mitigation measures to reduce any identified significant impacts.
The development permit approval process carries forward mitigation requirements in the form of conditions of approval, design specifications, tracking, inspection and enforcement actions.
These three “front-end” planning processes must be coordinated and linked to the later phases of BMP design, construction and operation for new development/significant redevelopment to help ensure storm water quality protection features are planned, designed and evaluated in accordance with goals for the protection of water quality and other environmental resources.
The City has used this model program in developing the new development/redevelopment plan contained in this section of the LIP. Subsequent sections describe:
• The organization structure for new development/redevelopment in the City • The assessment of the City’s General Plan and the need for amendment

A-7.3 General Plan Assessment and Amendment
The City is required by the Santa Ana Region Permit to minimize short and long-term impacts on receiving water quality from new development and significant redevelopment to the maximum extent practicable. The permit requires at a minimum that the City’s General Plan be reviewed and updated, as necessary, to ensure watershed and storm water quality and quantity management are considered as specified in Section XII of Santa Ana Region Permit.
The Santa Ana Region Permit requires:
“Permittees shall review their watershed protection principles and policies in their General Plan or related documents (such as Development Standards, Zoning Codes, Conditions of Approval, Development Project Guidance) to ensure that these principals and policies are properly considered and are incorporated into these documents.” To meet the Permit requirement, the City has undertaken the following actions consistent with the guidance provided in the DAMP, Section 7.4:
1. Review of City’s General Plan
The City has reviewed its General Plan Elements that cover land development issues, for which it may be appropriate to reflect watershed protection and storm water quality management policies. This included review of goals and policies in the following General Plan Elements:
• Land Use;
• Safety;
• Circulation and Infrastructure (i.e., transportation); • Public Facilities;
• Open Space; and
• Conservation.
The City reviewed development goals and policies, landscaping policies and requirements, open space goals and policies, including preservation or integration with natural features, water conservation policies, and public facilities operation and maintenance policies of these Elements. During the review, special attention was given to how the Elements address water quality protection from urban and storm water runoff. The City kept in mind the following questions during this review, which could trigger the need for specific storm water/urban runoff protection policies in the General Plan either as new policies and objectives or amended text to existing policies and objectives:
a) Are there sensitive water resources in the jurisdiction?
SECTION A-7, NEW DEVELOPMENT/REDEVELOPMENT
City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) A-7-5
b) Are there existing Total Maximum Daily Loads (TMDLs) or other such regulations pertaining to receiving waters in the jurisdiction?
c) Is major new development or significant redevelopment expected? d) Are major new infrastructure projects anticipated (e.g. roads, sewer, flood control, storm drains)?
e) Does storm water/urban runoff affect recreational use of water bodies within the jurisdiction?
The City has also reviewed and considered the following additional objectives to the General Plan and Elements, as specified by the Santa Ana Region Permit, Section XII.A.3:
a) Limit disturbance of natural water bodies and drainage systems; conserve natural areas; protect slopes and channels; and minimize impacts from storm water and urban runoff on the biological integrity of natural drainage systems and water bodies.
b) Minimize changes in hydrology and pollutant loading; require incorporation of control, including structural and non-structural BMPs, to mitigate the projected increases in pollutant loads and flows; ensure that post-development runoff rates and velocities from a site have no significant adverse impact on downstream erosion and stream habitat; minimize the quantity of storm water directed to impermeable surfaces and the MS4s; and maximize the percentage of permeable surfaces to allow more percolation of storm water into the ground;
c) Preserve wetlands, riparian corridors, and buffer zones and establish reasonable limits on the clearing of vegetation from the project site; d) Encourage the use of water quality wetlands, biofiltration swales, watershed-scale retrofits, etc., where such measures are likely to be effective and technically and economically feasible;
e) Provide for appropriate permanent measures to reduce storm water pollutant loads in storm water from the development site; and,
f) Establish development guidelines for areas particularly susceptible to erosion and sediment loss.
2. Assessment of Need to Amend City’s General Plan
Upon completing the review of its General Plan Elements, the City has determined that certain sections should be modified to include specific policies and objectives that address water quality protection as specified in the Fourth Term Permits and as described above. The need for and the extent of revisions to the General Plan were coordinated with the City Attorney and Planning Department.
SECTION A-7, NEW DEVELOPMENT/REDEVELOPMENT
City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) A-7-6
More specifically, the City has determined that the Land Use Section of the General Plan (Chapter 2) will likely be modified to include a policy that addresses incorporation of storm water quality protection into design standards for new development and significant redevelopment consistent with the Orange County Drainage Area Management Plan (DAMP) and city-specific Local Implementation Plan. Also, the Recreation Section (Chapter 4) of the General Plan will likely be amended to incorporate watershed protection objectives consistent with the Santa Ana Region Permit recommendations.
3. Schedule for Amending the City’s General Plan
The City will initiate a process to seek authorization from its City Council to amend its General Plan to incorporate watershed and storm water management principles. As part of the General Plan amendment process, maps will be revised, as necessary, to reflect location-specific watershed protection/storm water quality management policies, and to eliminate conflicts among land use districts, permitted land uses, and stormwater-specific goals and policies.
The process the City will proceed with the General Plan Amendment as follows:
a) Prepare draft text for General Plan Element(s) policy amendment(s) and related CEQA documentation.
b) Publish notice for Planning Commission hearing to consider General Plan Amendment.
c) Request Planning Commission approval through the public hearing process on proposed General Plan Amendment.
d) Incorporate any changes or additional studies, if required, as a result of the Planning Commission hearing.
e) Publish notice on City Council hearings on General Plan Amendment. f) Request City Council approval through the public hearing process on proposed General Plan Amendment.
The City will proceed with the General Plan Amendment by July 1, 2004.
The City’s schedule for amendments to the General Plan is as follows:
• February 1, 2003 through September, 2003 – Develop draft of proposed amendments to the General Plan
• September, 2003 – Submit application for General Plan amendment and proposed General Plan amendments to Planning Department • September, 2003 through January, 2004 – Conduct environmental review, refine proposed General Plan amendments, and conduct necessary reviews and workshops
• February, 2004 – Present proposed General Plan amendments to Planning Commission for approval to present to City Council
SECTION A-7, NEW DEVELOPMENT/REDEVELOPMENT
City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) A-7-7
• March, 2004 – Present proposed General Plan amendments to City Council for adoption
A-7.4 CEQA Environmental Review Process
a) The City is required by the Santa Ana Region Permit to minimize short and long-term impacts on receiving water quality from new development and redevelopment to the maximum extent practicable.
The Santa Ana Region Permit (Section XII.A.3) requires the City to review its CEQA document preparation process to ensure urban runoff-related issues are properly considered and addressed. If necessary, the City’s processes may be revised to consider and mitigate impacts to storm water quality. The Santa Ana Region Permit lists the following potential impacts to be considered by the City during the CEQA review:
a) Potential impact of project construction on storm water runoff; b) Potential impact of project’s post-construction activity on storm water runoff; c) Potential for discharge of storm water pollutants from areas of material storage, vehicle or equipment fueling, vehicle or equipment maintenance (including washing), waste handling, hazardous materials handling or storage, delivery areas, loading docks or other outdoor work areas;
d) Potential for discharge of storm water to affect the beneficial uses of the receiving waters; e) Potential for significant changes in the flow velocity or volume of storm water runoff to cause environmental harm; and
f) Potential for significant increases in erosion of the project site or surrounding areas.
These environmental review issues from the Permit have been considered in an evaluation of the City’s:
• CEQA Initial Study process (project application forms and checklists) and • EIR preparation and review process
The results of this evaluation are presented in the sub-sections below.
A-7.4.1 Project Application Form
After review by the City Attorney and Planning Staff, no changes are needed to the Project Application Form as questions related to urban runoff and storm water quality impacts are adequately addressed.
SECTION A-7, NEW DEVELOPMENT/REDEVELOPMENT
City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) A-7-8
A-7.4.2. Initial Study Checklist
The current Initial Study Checklist contained in Appendix G of the CEQA Guidelines (State of California Office of Planning and Research, February 2001) was recently updated and is used by the City in its environmental review process. This Checklist contains the following considerations under the environmental impact category “Hydrology and Water Quality (Section VIII) with respect to whether the project would:
a) Violate any water quality standards or waste discharge requirements? b) Substantially deplete groundwater supplies or interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level (e.g., the production rate of pre-existing nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted.
c) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, in a manner which would result in substantial erosion or siltation on- or off-site?
d) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, or substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or off-site? e) Create or contribute runoff water which would exceed the capacity of existing or planned storm water drainage systems or provide substantial additional sources of polluted runoff? f) Otherwise substantially degrade water quality?
g) Place housing within a 100-year flood hazard area as mapped on a federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood hazard delineation map? h) Place within a 100-year flood hazard area structures which would impede or redirect flood flows?
i) Expose people or structures to a significant risk of loss, injury or death involving flooding, including flooding as a result of the failure of a levee or dam? j) Inundation by seiche, tsunami, or mudflow?
The City has concluded that storm water/urban runoff/water quality considerations are generally covered in questions a) through f) of the CEQA Guidelines Appendix G checklist, but in some cases with less specificity than the questions provided in the Santa Ana Region Permit.
To ensure that the Initial Study thoroughly considers all issues listed in the Permit, the City has revised the CEQA Initial Study checklist to include some of the additional considerations provided in the Permit. Exhibit A-7.II contains the revised CEQA Initial Study Checklist for Section VIII, Hydrology and Water Quality containing the selected permit considerations. The proposed questions will be subject to review and revision by the City Attorney and Planning Staff prior to approval. The City has also added the following question to the Utilities and Service Systems Section (Section XVI) of the checklist:
SECTION A-7, NEW DEVELOPMENT/REDEVELOPMENT
City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) A-7-9
Would the project include a new or retrofitted storm water treatment control Best Management Practice (BMP), (e.g. water quality treatment basin, constructed treatment wetlands), the operation of which could result in significant environmental effects (e.g. increased vectors and odors)?
To support awareness of the Fourth Term Permit considerations described earlier, the City will take the following additional actions:
• Provide the updated checklist to all environmental planning staff for use in preparing and reviewing CEQA documents for internal City projects and when reviewing CEQA documents prepared by the private sector.
• Make available at the City counter the updated checklist for all consultants and other members of the private sector for use in preparing CEQA documents for private and public sector projects.
• Provide the updated checklist to all project applicants during the CEQA preliminary review process and to all environmental consultants on the city-approved list of contractors,. • Attend training programs hosted by the Principal Permittee to cover this topic. The City will provide training materials containing the additional questions and associated guidance on their use during various phases of the environmental review process.
A-7.4.3 Guidance for Preparing and Reviewing CEQA Initial Studies and Environmental Impact Reports (EIRs)
The guidance provided in the DAMP, Section 7, Exhibit 7.I will be used by the City in evaluating the CEQA Initial Study checklist questions in Section VIII. Hydrology and Water Quality (Appendix G of the CEQA Guidelines, State of California Office of Planning and Research, February 2001), including the additional questions to be considered by the Santa Ana Region Permit. This guidance is also applicable to the review and preparation of CEQA documents including Negative Declarations, Mitigated Negative Declarations and EIRs.
The guidance will be reviewed annually in conjunction with the Principal Permittee and other Permittees, updated as needed, and its status/use will be discussed in the Annual Progress Report.
A-7.5 Development Project Review, Approval and Permitting A-7.5.1 Project Review, Approval, and Permitting Process Overview During project review, approval, and permitting, the City shall require new development and significant redevelopment projects to address the quality and quantity of storm water runoff through the incorporation of permanent (post-construction) BMPs in project design. The City shall require project-specific Water Quality Management Plans (Project WQMPs) for all private and public projects that:
SECTION A-7, NEW DEVELOPMENT/REDEVELOPMENT
City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) A-7-10
• Qualify as one of the Priority Project Categories listed in Figure A-7.2, regardless of project size.
• Do not qualify as one of the Priority Project Categories but meet one of the following criteria:
o Require discretionary action that will include a precise plan of development o Require issuance of a non-residential plumbing permit The WQMP contains all the information specified for the Standard Urban Stormwater Mitigation Plan (SUSMP) and should for purposes of compliance be considered to be a SUSMP.
New development and significant redevelopment projects requiring a WQMP will be categorized by the City as either a Priority Project or a Non-Priority Project. The primary difference between a Priority Project and a Non-Priority Project is that Priority Projects will be required to include treatment control BMPs in project design. The detailed requirements for preparation of a WQMP are included in Section A-7.6 and a template for preparing a WQMP is provided as Exhibit A-7.IV.
“Significant Redevelopment” means development that would create or add at least 5,000 square feet of impervious surfaces on an already developed site. Significant redevelopment includes, but is not limited to:
• Expansion of a building footprint
• Addition to or replacement of a structure
• Replacement of an impervious surface that is not part of a routine maintenance activity • Land disturbing activities related with structural or impervious surfaces.
Replacement of impervious surfaces includes any activity that is not part of a routine maintenance activity where impervious material(s) are removed, exposing underlying soil during construction. Significant redevelopment does not include trenching and resurfacing associated with utility work; resurfacing and reconfiguring surface parking lots; new sidewalk construction, pedestrian ramps, or bike lane on public and private existing roads; and replacement of damaged pavement.
Significant Redevelopment projects may fall into one of several categories:
• Following redevelopment, the entire development (including the redeveloped area) would meet one of the Project Priority categories listed in Figure A-7.2. The project would be considered a Priority Project and require a Project WQMP including Treatment Control BMPs. Where the significant redevelopment results in an increase of less than fifty percent of the impervious surface of a previously existing development, and the existing development was not subject to WQMP requirements, the treatment requirements apply only to the addition, and not to the entire development.
SECTION A-7, NEW DEVELOPMENT/REDEVELOPMENT
City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) A-7-11
• Following redevelopment, the entire development (including the redeveloped area) would not meet one of the Project Priority categories listed in Figure A-7.2, but would require discretionary action that will include a precise plan of development, or require issuance of a non-residential plumbing permit. The project would be considered a NonPriority Project and require a Project WQMP but would not require Treatment Control BMPs.
• The redevelopment activity would not result in a Priority Project and would not require discretionary action that will include a precise plan of development or issuance of a non-residential plumbing permit. The project would not require a Project WQMP.
The City shall require project applicants to submit a Project WQMP at one or both points in the project planning and permitting stage:
• During the discretionary approval process (land use permit) of a proposed project, when the City must exercise judgment or deliberation in order to approve or disapprove a new development or significant redevelopment project, or • During the ministerial approval process of issuing a grading, building, demolition, or similar “construction” permits in which only fixed standards or objective measures are applied.
A-7.5.2 Public Agency Projects
The City has incorporated the requirement for a Project WQMP into the process of planning, design, approval, and construction oversight of its public agency projects. Depending upon the type of public agency project being planned or designed, the City’s design architect/engineering contractor will prepare the Project WQMP for a public facility project.
The City will not require a WQMP for public agency projects consisting of routine maintenance or emergency construction activities required to protect public health and safety; interior remodeling with no outside exposure of construction materials or construction waste to storm water; mechanical permit work; electrical permit work; and sign permit work.
The types of public agency projects for which the City will require a Project WQMP include, but are not limited to:
• Parks and recreation facilities
• Public Buildings
• Streets and roadways
• Above ground drainage facilities (e.g. channels, basins) The categories of Priority Projects are listed in Figure A-7.2. Although the City does not plan and design some of these categories of projects per se, some public agency projects may have similar functions or characteristics or may conduct similar activities after construction is
SECTION A-7, NEW DEVELOPMENT/REDEVELOPMENT
City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) A-7-12
completed. Therefore, some of the City’s public agency projects may fall under the Priority Projects category requiring Treatment Control BMPs. For example, a new corporation yard may include a vehicle and equipment maintenance facility, which is very similar to an automotive repair shop. A new civic center or library may be considered a Priority Project since it is very similar in its characteristics to a commercial office building. A new senior citizens center or a jail may have a cafeteria, which is very similar to a restaurant, and, therefore may be categorized as a Priority Project.
A-7.5.3 Conditions of Approval
The City has reviewed its standard conditions of approval to ensure that the existing standard conditions are not in conflict with any provisions of the Santa Ana Region Permit, the DAMP, California’s General Permit for Stormwater Discharges Associated with Construction Activity, California’s General Permit for Stormwater Discharges Associated with Industrial Activity, and where conflicts were identified, the City has revised the existing standard conditions of approval.
The City shall utilize the following standard conditions of approval to protect receiving water quality from the short-term and long-term impacts of new development and redevelopment:

Local Implementation Plan (LIP) A-7-16
Although both Priority and Non-Priority projects require the preparation of a WQMP, the scope of the WQMP differs. The WQMP for a Priority Project must address:
• Site Design BMPs,
• Routine structural and non-structural Source Control BMPs, • Treatment Control BMPs, including consideration of a regional or watershed approach, and
• The mechanism(s) by which long-term operation and maintenance of all structural BMPs will be provided.
The WQMP for a Non-Priority Project must address:
• Routine structural and non-structural Source Control BMPs, • Consideration of Site Design BMPs, and
• The mechanism(s) by which long-term operation and maintenance of all structural BMPs will be provided.
To assure thorough and consistent reviews of Project WQMPs, the City will utilize the WQMP Checklist provided in Exhibit A-7.III and approve in writing appropriately completed Project WQMPs.
A-7.5.5 Plan Check: Issuance of Grading or Building Permits The construction plans submitted by the applicant for plan check must incorporate all of the structural BMPs identified in an approved Project WQMP. Therefore, the City will encourage applicants to obtain approval of the final Project WQMP prior to submitting construction plans for plan check.
General or Special Notes for Plan Sheets
Prior to the issuance of a grading or building permit, the City shall require the permit applicant to include the following as general or special notes on the plan sheets for new development or significant redevelopment projects:
• Sediment from areas disturbed by construction shall be retained on site using structural controls to the maximum extent practicable.
• Stockpiles of soil shall be properly contained to minimize sediment transport from the site to streets, drainage facilities or adjacent properties via runoff, vehicle tracking, or wind.
• Appropriate BMPs for construction-related materials, wastes, spills or resides shall be implemented to minimize transport from the site to streets, drainage facilities, or adjoining property by wind or runoff.
SECTION A-7, NEW DEVELOPMENT/REDEVELOPMENT
City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) A-7-17
• Runoff from equipment and vehicle washing shall be contained at construction sites unless treated to remove sediment and other pollutants. • All construction contractor and subcontractor personnel are to be made aware of the required best management practices and good housekeeping measures for the project site and any associated construction staging areas.
• At the end of each day of construction activity all construction debris and waste materials shall be collected and properly disposed in trash or recycle bins. • Construction sites shall be maintained in such a condition that an anticipated storm does not carry wastes or pollutants off the site. Discharges of material other than stormwater are allowed only when necessary for performance and completion of construction practices and where they do not: cause or contribute to a violation of any water quality standard; cause or threaten to cause pollution, contamination or nuisance; or contain a hazardous substance in a quantity reportable under Federal Regulations 40 CFR Parts 117 and 302.
Potential pollutants include but are not limited to: solid or liquid chemical spills; wastes from paints, stains, sealants, glues, lime, pesticides, herbicides, wood preservatives and solvents, asbestos fibers, paint flakes or stucco fragments; fuels, oils, lubricants, and hydraulic, radiator or battery fluids; concrete, detergent or floatable wastes; wastes from any engine/equipment steam cleaning or chemical degreasing; and superchlorinated potable water line flushings.
During construction, disposal of such materials should occur in a specified and controlled temporary area on-site physically separated from potential stormwater runoff, with ultimate disposal in accordance with local, state and federal requirements. • Dewatering of contaminated groundwater, or discharging contaminated soils via surface erosion is prohibited. Dewatering of non-contaminated groundwater requires a National Pollutant Discharge Elimination System (NPDES) permit from the respective State Regional Water Quality Control Board.
Plan Check for Private Projects with Land Use Permits
For projects with land use permits, the City shall review the environmental (CEQA) documentation (including the Mitigation Monitoring and Reporting Program), the conditions of approval and the approved Project WQMP for an understanding of the water quality issues and structural BMPs required. The City shall review construction plans for conformity with the approved Project WQMP. If the selected BMPs were approved in concept during the land use entitlement process, the City shall require the applicant to submit detailed construction plans showing locations and design details of all BMPs that are in substantial conformance with the preliminary approvals. The City shall review a project’s construction plans to assure that the
SECTION A-7, NEW DEVELOPMENT/REDEVELOPMENT
City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) A-7-18
plans are consistent with the BMP design criteria and guidance provided in DAMP Section 7, Exhibit 7.II.
Plan Check for Projects with By-Right Zoning (Ministerial Projects) For projects with by-right zoning or projects that do not need discretionary review, the City shall first review the proposed Project WQMP for conformity with the requirements described in DAMP Section 7.7 and DAMP Section 7, Exhibit 7.II. The approved Project WQMP shall then be used in reviewing the construction plans for consistency with the BMP design criteria and guidance provided in DAMP Section 7, Exhibit 7.II.
Plan Check for Public Agency Projects
Prior to initiating grading or construction activities, the City shall ensure that the construction plans for its public works projects reflect the structural BMPs described in the approved Project WQMP. In conducting the design review process for its public agency projects, the City shall review the construction plans and specifications for conformity with the approved Project WQMP and for consistency with the BMP design criteria and guidance provided in DAMP Section 7, Exhibit 7.II.
Plan Check for Projects with Alternative Treatment Control BMPs (See DAMP Section 7, Exhibit 7.II Section 3.3.3.)
If an applicant elected to utilize Alternative Treatment Control BMPs in a project’s construction plans, the City shall require the project’s engineer of record to certify that the Alternative Treatment Control BMPs are equally or more effective in pollutant reduction than comparable BMPs found in the Model WQMP.
A-7.5.6 Permit Closeout, Certificates of Use, and Certificates of Occupancy The Project WQMP continues with the property after the completion of the construction phase and the City may require that the terms, conditions and requirements be recorded with the County Recorder’s office by the property owner or any successive owner as authorized by the Water Quality Ordinance. The end of the construction phase therefore represents a transition from the New Development/Significant Redevelopment Program to the Existing Development Program. Accompanying this is a close out of permits and issuance of certificates of use and occupancy. The City will use this juncture to assure satisfactory completion of all requirements in the Project WQMP by requiring the applicant to:
o Demonstrate that all structural BMPs described in the Project WQMP have been constructed and installed in conformance with approved plans and specifications, and signed off by professional Engineer,
o Schedule City progress inspection of the construction of the structural BMPs • Prepare and submit for review and approval an O&M Plan for all structural BMPs,
SECTION A-7, NEW DEVELOPMENT/REDEVELOPMENT
City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) A-7-19
• Demonstrate that a mechanism or agreement acceptable to the City has been executed for the long-term funding and performance of BMP operation, maintenance, repair, and/or replacement. Demonstrate that the applicant is prepared to implement all non-structural BMPs described in the Project WQMP, • Demonstrate that an adequate number of copies of the Project WQMP are available onsite, and
• For industrial facilities subject to California’s General Permit for Stormwater Discharges Associated with Industrial Activity as defined by Standard Industrial Classification (SIC) code, demonstrate that coverage has been obtained by providing a copy of the Notice of Intent (NOI) submitted to the State Water Resources Control Board and a copy of the notification of the issuance of a Waste Discharge Identification (WDID) Number.
The O&M Plan for structural BMPs that is prepared by the applicant for private sector projects shall describe and/or include:
• Structural BMPs
• Employee responsibilities and training for BMP operation and maintenance • Operating schedule
• Maintenance frequency and schedule
• Specific maintenance activities
• Required permits from resource agencies, if any
• Forms to be used in documenting maintenance activities • Notification to Orange County Vector Control District of the structural BMPs in place
• Recordkeeping requirements (at least 5 years)
At a minimum, the City shall require the annual inspection and maintenance of all structural BMPs by the responsible party designated in the WQMP. Following satisfactory inspection, those structural BMPs agreed during the planning process to be within City right-of-ways, or on land to be dedicated to City ownership will be accepted. Upon acceptance, responsibility for operation and maintenance will transfer from the developer or contractor to the appropriate City department, including the funding mechanism identified in the approved Project WQMP.
If a property owner or a private entity, such as a homeowners association (HOA), retains or assumes responsibility for operation and maintenance of structural BMPs, the City shall require access for inspection through an agreement. If the City will be responsible for operating and maintaining structural BMPs on private property, an easement will be established to allow for entry and proper management of the BMPs. Such access easements shall be binding throughout the life of the project, or until the BMPs requiring access are acceptably replaced with a BMP not requiring access. Funding for the long-term operation and maintenance of structural BMPs will
SECTION A-7, NEW DEVELOPMENT/REDEVELOPMENT
City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) A-7-20
be guaranteed via mechanisms such as approved assessment districts or other funding mechanisms (i.e. front-funded).
Public Agency Projects
For the City’s public facility projects, upon completion of construction when contract close-out occurs, the responsibility for operation and maintenance of the structural BMPs will transfer from the contractor to the appropriate City department. The City has the authority to approve the transfer of structural BMPs to any other public entity within its jurisdiction and shall negotiate satisfactory operation and maintenance standards with the public agencies accepting the operation and maintenance responsibilities. Alternatively, the responsibility for the operation and maintenance of structural BMPs may be transferred to a private entity through contracts or lease agreements. In any such transfer agreement, the City shall be identified as a Fourth-party beneficiary empowered to enforce maintenance agreements.
A-7.6 Water Quality Management Plan (WQMP) Preparation
In accordance with the requirements in the Development Project Review, Approval and Permitting process stated previously, the City will require Project WQMPs to be prepared using the guidelines set forth in the Model WQMP, provided in DAMP Section 7, Exhibit 7.II., and the submittal template provided as Exhibit A-7.IV. Elements of WQMP development are illustrated in the following figure:

BMP Implementation
Consistent with the Model WQMP, the City will require Priority Projects to:
Implement all Source Control BMPs (routine non-structural and routine structural) unless not applicable to the project;
Consider the implementation of Site Design BMPs and document those BMPs included and those not included; and
Either:
o Implement Treatment Control BMPs including a selection of such BMPs into the project design, (unless a waiver is granted for infeasibility of all Treatment Control BMPs, see Model WQMP, DAMP Section 7, Exhibit 7.II, Section 6.0 for details);
or:
o Participate in or contribute to an acceptable regional or watershed management program.
The City will require all other (Non-Priority) projects to implement Source Control BMPs and consider implementing Site Design BMPs. Once a project reaches the plan check phase, the applicant will be required to submit the approved Project WQMP together with construction plans that incorporate the selected BMPs. Projects that have not been subject to the land use entitlement process or other discretionary review will still need to prepare and obtain approval of a Project WQMP, and include it with the plan check review submittal.
A combination of Source Control BMPs (routine non-structural and routine structural BMPs) and Site Design BMPs is generally the most effective means of pollution prevention and because they minimize the need for treatment. The City will require Treatment Control BMPs to be considered for all Priority Projects in addition to Source Controls to meet requirements of the Fourth Term Permits to minimize, to the maximum extent practicable, the discharge of pollutants to the storm drain system or receiving waters.
The categories of stormwater pollution control BMPs are summarized in Table A-7.1, together with applicable projects and primary pollution prevention objectives of the BMPs.
Routine Source Control BMPs
Routine structural Source Control BMPs are low-technology practices designed to prevent pollutants from contacting stormwater runoff or to prevent discharge of contaminated runoff to the storm drainage system. Routine non-structural Source Control BMPs are listed in Table A7.2. Routine structural Source Control BMPs are listed in Table A-7.3.

Site Design BMPs
The principal objective of Site Design BMPs is to prevent pollution of stormwater by minimizing the introduction of pollutants and conditions of concern that may result in significant impacts generated from site runoff to the storm water conveyance system. One approach to achieve this objective is to reduce stormwater runoff flows and volumes and reduce pollutants through appropriate Site Design BMPs.
Start at the Source (Bay Area Stormwater Management Association 1999) provides design guidance and techniques for implementing site design BMPs. Benefits derived from this approach include:
Reduced size of downstream treatment controls and conveyance systems; Reduced pollutant loading to treatment controls; and
Reduced hydraulic impact on receiving streams
Site Design BMPs should be considered for all projects. Site Design BMPs include the design techniques listed in Table A-7.4.
Table A-7.4
Site Design BMP Techniques
Minimize Impervious Area/Maximize Permeability (C-Factor Reduction) Minimize Directly Connected Impervious Areas (DCIAs) (C-Factor Reduction) Create Reduced or “Zero Discharge” Areas (Runoff Volume Reduction) Conserve Natural Areas (C-Factor Reduction)
Fact sheets for routine structural Source Control BMPs and Site Design BMPs are presented in Exhibit A-7.V. The fact sheets include design criteria established to ensure effective implementation of the required Site Design BMPs and will be made available by the City.
Treatment Control BMPs
Treatment Control BMPs are engineered technologies designed to remove pollutants from stormwater runoff and are required to augment Source Control and Site Design BMPs to reduce pollution from stormwater discharges to the maximum extent practicable. The type of Treatment Control BMP(s) to be implemented at a site depends on a number of factors including: type of pollutants in the stormwater runoff, volume or flow of stormwater runoff to be treated, project site conditions, receiving water conditions, and General Industrial Permit requirements, when applicable. Land requirements, and costs to design, construct and maintain Treatment Control BMPs vary by Treatment Control BMP.
SECTION A-7, NEW DEVELOPMENT/REDEVELOPMENT
City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) A-7-26
Unlike flood control measures that are designed to handle peak flows, stormwater Treatment Control BMPs are designed to treat the more frequent, lower-flow storm events, or the first flush portions of runoff from larger storm events (typically referred to as the first-flush events).
Small, frequent storm events represent most of the total average annual rainfall for the area.
The flow and volume from such small events is targeted for treatment.
The primary control strategy for designing BMPs is to treat the Stormwater Quality Design Flow (SQDF) or the Stormwater Quality Design Volume (SQDV) of the stormwater runoff.
Table A-7-5 lists BMPs along with the basis of design, SQDF or SQDV, to be used for designing the BMP. The Model WQMP (DAMP Section 7, Exhibit 7-II) shows the approach that should be used to calculate the SQDF and/or SQDV.

Local Implementation Plan (LIP) A-7-27
Regional or Watershed Programs
If the path of a regional of watershed-based program is selected, the regional or watershed BMPs selected must be designed to provide equivalent treatment objectives for the entire area.
More detailed analysis (such as detailed planning and modeling) should be employed and cross-jurisdictional issues must be clearly defined and coordinated (see DAMP Section 7 for a more detailed discussion of the applicability of regional or watershed programs).
A-7.7 Post Construction BMP Inspection and Verification The City will conduct verifications to assure that implementation and appropriate maintenance described in the WQMP are taking place at structural and non-structural BMPs during the post construction phase. Assessment of BMP effectiveness will take place during verification. The goal is to perform verifications at 90% of developments with approved Project WQMPs during the Fourth Term Permit period. The number of verifications necessary to achieve the above goal will be based on either the total area of approved Project WQMP projects, or the total number of Project WQMPs approved.
Verification of BMP implementation and ongoing maintenance will be conducted by selfcertifications, inspection , surveys, or other equally effective approaches. A summary of the inspections conducted and any assessments of effectiveness will be provided in the annual progress report.
A-7.8 Education and Training
To assist responsible municipal staff and contract staff in understanding the DAMP’s Model New Development/Redevelopment Program, annual training sessions will be conducted. In addition to Permittee sponsored training, staff may also attend training seminars or workshops related to general water quality and stormwater management during construction, conducted by other organizations.
A-7.8.1 Training Modules
Two training modules have been prepared that cover different aspects of the Model New Development/Significant Redevelopment Program. These modules are provided in DAMP Appendix B-7.
New Development/Significant Redevelopment Program Management (DAMP Appendix B, Exhibit B7.I) This training module is for Permittee Stormwater Program managers and the managers of a Permittee’s planning and building departments. It provides an overview of the Storm Water Program as it pertains to a Permittee’s General Plan, the preparation and review of environmental documents (Initial Studies, EIRs, EISs, Negative Declarations, Mitigated Negative Declarations, etc.), conditions of approval for projects, the review of Project WQMPs,
SECTION A-7, NEW DEVELOPMENT/REDEVELOPMENT
City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) A-7-28
plan check, and permit closeout. The training module also briefly describes a Permittee’s responsibility for verifying and inspecting permanent BMPs and for assessing the effectiveness of the New Development/Significant Redevelopment Program element.
Project Planning and Design: Environmental Review, Planning and Permitting, and WQMP Development (DAMP Appendix B, Exhibit B.7.II)
This training module is targeted to planners, plan checkers, developers and engineers, and will address: the laws and regulations applicable to new development/significant redevelopment; the connection between new development/significant redevelopment and water quality; how to review and prepare CEQA compliance documents with regard to storm water/urban runoff effects, how to develop and review a Project WQMP; and how to design and incorporate into a project Source Control, Site Design and Treatment Control BMPs to minimize impact to receiving waters.
A-7.8.2 Record Keeping
Records of training provided to City staff will be maintained to allow a determination of:
• Which staff require which training
• When training sessions were conducted
• Compliance with the permit requirements
In addition to the Permittee-sponsored training, City staff may also attend various other workshop or training events as they take place throughout the year. These types of events may include local or national organization sponsored training.
A-7.9 Program Effectiveness Assessment
The City will submit an annual progress report each year to the Principal Permittee (see DAMP Appendix C, Section C-7). This report will provide the basis for evaluating the City’s efforts towards the reduction of pollutants from new development and significant redevelopment. The annual progress report will demonstrate a commitment to pollution prevention and source reduction processes in new development/redevelopment projects in the City. Future annual progress reports will include:
Changes made to the City’s General Plan, CEQA and development review processes Information on WQMPs approved and verified by the City; Documentation of training received by the City staff.

1 SAMPLE GENERAL PLAN AMENDMENT TEXT AND SAMPLE URBAN RUNOFF
WATER QUALITY GENERAL PLAN ELEMENT
Taken from the Model Urban Runoff Program, A How to Guide for Developing Urban Runoff Program for Small Municipalities (City of Monterey, et al, July 1998) SAMPLE URBAN RUNOFF WATER QUALITY ELEMENT1
A. Urban Runoff Water Quality
1. Introduction
There are many major sources of water pollution nationwide. Pollution that originates from a specific, discrete location, referred to as a "point" source, includes: effluent from municipal wastewater treatment plants; regulated industrial wastewater discharges; hazardous wastes and materials from spills, mishandling, and industrial accidents; effluent from inadequately functioning septic systems; and illegal dumping activities.
There are also pollutants contained in urban stormwater runoff, referred to as "non-point" source pollution, due to the diffuse origins of such pollutants. These include metals, organic wastes, pesticides, and a variety of other pollutants. Other types of pollutants include those that result from disinfection of drinking water and the intrusion of salt water from the ocean into nearby groundwater aquifers. The Water Quality and Watershed Management element is designed to protect receiving waters from those pollutants referred to as "non-point" source.
In both urban and areas of the state, substances are deposited on the surface of the land which are carried into the area’s drainage system by stormwater runoff. However, given the much more extensive amount of impervious surface area within urbanized areas, non-point source pollution is often an urban area pollution problem. Although it s a much less obvious source of pollution, it can be a significant contributor of pollutants to receiving waters throughout the state.
2. Urban Runoff Pollution Control
GOAL: Protect on and enhancement of local urban creeks, lakes, wetlands, and beaches is a city goal. Policies and programs should reflect this goal by providing ways to prevent water pollution before it occurs. Achievement of this goal will result in maintaining and enhancing the quality of life valued by residents and visitors.
Policies & Programs
The intent of this general plan is to provide policies and programs that will protect receiving waters from pollutants discharged to the storm drain system. The following policies and programs address non-point source pollution issues and their "solutions."
1 Source: Model Urban Runoff Program, A How to Guide for Developing Urban Runoff Programs for Small Municipalities, prepared by City of Monterey, City of Santa Cruz, California Coastal Commission, Monterey Bay National Marine Sanctuary, Association of Monterey Bay Area Governments, Woodward-Clyde, and Central Coast Regional Water Quality Control Board, July 1998)
2 a. Public Education
Policy 1. Coordinate with other agencies in the watershed area to develop public education programs that will get the most exposure for the money spent.
Program 1a. Encourage local schools, business and neighborhood associations to become educated in urban runoff issues using the available resources of the City and other involved agencies.
Program 1b. Establish a business education program to provide information and incentives to local businesses for the implementation of "Best Management Practices" for pollution prevention and control.
b. Public Outreach
Policy 2. Coordinate with existing public outreach programs and create programs to involve the community in addressing urban runoff pollution problems and raising awareness of how individuals’ activities contribute to urban runoff pollution.
Program 2a: Establish a storm drain stenciling program and/or coordinate with an existing program to label catch basins with warning signs (No Dumping- Flows to Bay/Creek/River/Lake).
Program 2b: Establish a local pollution sampling and monitoring program including citizens monitoring and/or coordinate with existing regional programs.
Program 2c: Encourage public input on development and implementation of urban runoff pollution control and programs by meeting with or sending copies of proposed plans to neighborhood and business association representatives.
c. Illicit Discharge Detection and Elimination
Policy 3: Encourage measures to promote proper disposal of pollutants to the sanitary sewer or hazardous waste facilities rather than to the storm drainage system.
Program 3a: Establish and promote used oil recycling and/or hazardous waste recycling facilities and drop-off locations.
Program 3b: Review plans for new development and redevelopment for connections to storm drain system. Inspectors should field check for such connections when performing building inspections.
Program 3c: Establish a city program for following up on complaints of illegal discharges to the storm drain and creeks.
d. Construction Site Stormwater Discharge Control
Policy 4: Encourage contractors to comply with accepted stormwater pollution prevention planning practices for all projects subject to erosion potential.
Program 4a: Institute routine inspection practices and training for Building Inspectors and Public Works Inspectors to check for proper erosion control methods and housekeeping practices during construction.
3 Program 4b: Enforce requirements for contractors to provide Stormwater Pollution Prevention Plans, grading and housekeeping plans including erosion control measures as necessary.
Program 4c: Enforce erosion control ordinances.
e. Post-Construction Controls for Development and Redevelopment Policy 5: Establish requirements for installation and maintenance of stormwater structural controls to reduce peak discharges and to maximize pollutant removal from runoff.
Program 5a: Establish discharge limits and/or maintenance requirements to be included in site plan f view covenants, conditions, and restrictions (CC&R's) for private development, and requirements for City projects. These requirements should be included by Public Works and Community Development Departments responsible for project management.
Program 5b: Where feasible, encourage establishment or re-establishment of vegetated wetland areas, which can effectively serve as natural water pollutant removal filtration systems. Other vegetated areas (e.g., buffer strips) can also effectively remove pollutants from runoff, and their establishment should also be encouraged.
f. Good Housekeeping Practices for Municipal Operations Policy 6: Establish and coordinate good housekeeping procedures for all City Departments to sure that water quality objectives are not threatened by in- house operations and example is established for the community.
Program 6a: Incorporate water quality objectives into existing regular safety inspections.
Institute additional inspections as necessary.
Program 6b: Establish Best Management Practices to be followed by City Departments and hold training sessions on a regular basis to ensure that employees are familiar with those practices.
Program 6c: Educate City employees on sources and impacts of pollutants in urban runoff and actions that can be taken to reduce these sources.
Program 6d: Ensure that contractors used by City are aware of and implement urban runoff control programs.

Background Statements
The U.S. Environmental Protection Agency has identified urban surface runoff as a significant cause of water pollution in the United States. Surface runoff water may contain a variety of pollutants including: paints, varnishes and solvents; oil and other automotive fluids; nonhazardous liquid and solid wastes and yard wastes; refuse, rubbish, garbage, litter, or other discarded or abandoned objects, articles, and accumulations so that same may cause or contribute to pollution; floatables; pesticides, herbicides, and fertilizers; hazardous substances and wastes; sewage, fecal coliform and pathogens; dissolved and particulate metals; animal wastes; wastes and residues that result from constructing a building or structure (including but not limited to sediments, slurries, and concrete rinsates); and noxious or offensive matter of any kind. These pollutants are typically generated from a variety of diffuse sources present throughout the urban environment, and are referred to herein as "non-point" source pollution.
Surface Runoff
Common pollutants contained in urban runoff generally include:
• tire wear material;
• metals such as copper, chromium, lead, cadmium and other toxics produced by combustion, leakages, metal plating, vehicle wear, and weathered paint; • motor fuels, lubricants, and other fluids which are inadvertently spilled or leak from vehicles, or which are purposely dumped into the ground or into the storm drainage system;
• pesticides, herbicides, and fertilizers applied to agricultural crops, landscaping, and roadsides;
• biological contaminants from litter, organic matter, and animal wastes; and. detergents and solvents used to clean urban surfaces.
Some of these pollutants are introduced to the drainage system by individuals who are uninformed of their effects on the environment. One of the most notorious examples is that of individuals who dump used motor oil into storm drains or onto the ground. Few are aware that one quart of used motor oil is capable of contaminating 250,000 gallons of water, or that substances disposed of into the stormwater drainage system are not treated before entering receiving waters. Other substances are introduced as the result of intentional efforts to avoid the costs of legal disposal and conformance with water quality regulations. The "Illegal Dumping Elimination Program" is one component of the overall Non-point Source Pollution Control Program intended to help reduce such activities.
The variety of sources and concentrations of pollutants, as well as the variability of runoff, make the "end-of-pipe" treatment methods, which are often used to address industrial discharges, impractical and ineffective alternatives for non-point source pollution control. Although not without its own difficulties, the most effective means of reducing non-point source pollution are

5 those which prevent pollutants from being introduced into, or prevent their conveyance through, the storm drainage system to receiving waters. Prevention is the key to a successful urban runoff program with treatment of non-point source pollution used only if prevention fails to meet the goals of the Clean Water Act.
Comprehensive Watershed Management Planning
Increasingly, the governmental entities responsible for water supply will rely upon comprehensive watershed management planning in order to ensure that the quality of the waters entering local reservoirs and rivers charging groundwater are of the highest quality These plans involve the cooperation and coordination of many jurisdictions having land use authority and regulatory powers within the watershed or drainage area. Subjects of major concern include retention of ground cover and vegetation, timber harvesting, development impacts, land use, grading and earth moving, grazing practices, and other activities that affect urban runoff, primarily in the rural areas of the watershed Strategies, Policies, and Implementation
A comprehensive approach to managing water quality should include the following basic strategies, in addition to ongoing point source regulation:
Strategy #1: Reduce Non- Point Source Pollution
Strategy #2: Restore Wetlands, Riparian Areas, and Other Habitats that Improve Water Quality Strategy #3: Prepare and Implement Comprehensive Watershed Management Plans These strategies reflect a comprehensive approach to safeguard water resources, improve water quality, and protect the health of species dependent on them, including humans.
INSERTIONS
Urban Runoff
Urban runoff from [municipality] is discharged into local creeks that empty into [local receiving water]. Both state and fed rat authorities have identified urban runoff as a major source of pollution adversely affecting the beneficial uses of waters statewide. Some of those impaired beneficial uses are recreation, commercial and sport fishing, estuarine habitat, and the preservation of rare and endangered species. [The state has issued a National Pollutant Discharge Elimination System (NPDES) Permit to [municipality] for which a municipal stormwater management program must be developed and implemented.] It is extremely difficult and expensive to control the composition of urban runoff discharges through conventional wastewater treatment technologies. Therefore, it is critical that [municipality] implement measures to identify and control the sources of pollutants before they are actually discharged into the storm drain system. In order to control the non-point sources of pollutants, [municipality] has reviewed the types of land uses and practices which have the potential to discharge pollutants into the storm drain system. In doing so, [municipality] has identified several key areas to control and reduce potential pollutants in urban runoff including:
industrial and commercial discharge, new development and redevelopment, construction
6 activities, illegal dumping, illicit connections to storm drains, public information and participation, and public agency activities.
General Plan Elements
A. Land Use
Apply the following watershed protection activities to all new development and redevelopment proposals during the planning, project review, and permitting processes:
• Avoid conversion of areas particularly susceptible to erosion and sediment loss (e.g., steep slopes) and/or establish development guidance that identifies these areas and protects them from erosion and sediment loss. It is a general policy to limit grading permits or allow grading in those areas susceptible to erosion from October through April.
• In order to prevent undue erosion of creek banks, [municipality] should seek to retain creek channels in their natural state. Regulate development near watercourses to reduce erosion and pollution and to provide open natural areas. • Preserve or restore areas that provide water quality benefits and/or are necessary to maintain riparian and aquatic biota.
• Promote site development that limits impact on and protects the natural integrity of topography, drainage systems, and water bodies.
• Promote integration of stormwater quality protection into construction and postconstruction activities at all development sites. Evaluate the ability of a land parcel to detain excess stormwater runoff and require incorporation of appropriate controls, for example, through use of detention facilities. As part of site approval or as a condition of tentative maps, require permanent stormwater pollution control measures or systems and an ongoing maintenance program, as necessary.
B. Circulation
• Work to reduce transportation related sources of water pollution, particularly in stormwater runoff. Any means by which vehicle-miles-traveled are reduced benefits congestion and reduces air and water pollution.
• Recognize and publicize the relationship between air pollution and water pollution in the deposition onto streets and other surfaces of airborne contaminants, including metals and fine particulate matter (PM10).
C. Housing
• Housing policies and programs stated in the General Plan should be consistent with water quality preservation goals stated within the conservation element.
D. Conservation
• Comprehensive watershed management plans should be developed and implemented for drainage basins in [municipality]. In order to do this, close coordination should take
7 place among the County, the cities, and the various special districts whose decisions and activities affect the county's and cities' watersheds and other natural resources. • [Municipality] shall implement urban runoff pollution control measures and programs to attempt to reduce and control the discharge of pollutants into the municipality's storm drains and local creeks to the maximum extent practicable. • Reduce the quantity of runoff and discharge of pollutants to the maximum extent practicable by integrating surface runoff controls into new development and redevelopment land use decisions.
• [Municipality] should support, and contribute to, the acquisition of areas of open space that have water quality significance by City and County Parks, State Parks, and other agencies and non-profit organizations for permanent preservation. • Work with other local government agencies on land use issues county-wide in order to maintain a watershed-based approach to land use, flood control, and non-point source pollution prevention. Hazard and resource areas with the following characteristics shall be considered unsuited for urban development: flood potential; wetlands; riparian corridors; and areas generally above 25% slope.
• Land uses which pose a major threat to water quality, including commercial and industrial uses such as automobile dismantlers, transportation and vehicle storage facilities, waste transfer disposal facilities, light industries, and other uses that have a significant potential for pollution, shall not be located within the vicinity of streams, reservoirs, or percolation facilities or where pollutants could easily come in contact with flood waters, high groundwater, flowing streams, or reservoirs. Such uses shall be required to reduce any threat of pollution to an insignificant level as a condition of approval.
• Particulate matter pollution shall be minimized through control over new and redevelopment (including erosion and sediment controls on grading, quarrying, vegetation removal, construction and demolition), industrial processes, parking lots, and other activities that pose such a threat to water quality.
E. Open Space
• Open space policies and programs should be consistent with those water quality policies and programs set forth in the conservation element. Open space areas should be managed with erosion control and pollution prevention measures in the forefront.
F. Safety
• Water quality protection measures set forth throughout the General Plan are the result of United States Environmental Protection Agency legislation under the Clean Water Act. The intent of these measures is to protect the health and safety of humans as well as to protect the beneficial uses of receiving waters.
G. Noise
• Not applicable to water quality.

The following is a summary of major concerns relative to this WQMP submittal:
Exhibit A-7.IV
Model Water Quality Management Plan
(WQMP) Template
CITY OF YORBA LINDA
PREPARING A WATER QUALITY MANAGEMENT PLAN (WQMP)
A Brief Overview
What is a WQMP?
All new development and redevelopment projects, with the exception of the construction of a singlefamily detached dwelling unit, require the submittal of a Water Quality Management Plan (WQMP).
A Project WQMP is a plan for managing the quality of storm water or urban runoff that flows from a developed site after construction is completed and the facilities or structures are occupied and/or operational. Final Project WQMPs must be approved prior to issuance of building and grading permits.
A WQMP describes the Best Management Practices (BMPs) that will be implemented and maintained throughout the life of a project and is used by property owners, facility operators, tenants, facility employees, maintenance contractors, etc. to prevent and minimize water pollution that can be caused by storm water or urban runoff.
The City will review the WQMP and revisions will be made by the applicant, if necessary. Once a final WQMP is approved, the applicant will be required to submit three final copies of the entire document and three stand-alone copies of the approved WQMP exhibit showing the location of all structural BMPs. Two of the copies will remain with the City/Plan Checker and the other copy will be returned to the applicant with an approval stamp. The applicant will be responsible for submitting an approved, stamped WQMP exhibit as an attachment to both grading plans and building plans for review during the plan check phase.
What Projects Require a WQMP?
All projects within the City of Yorba Linda require the preparation and submittal of a WQMP. An exception to this is for the construction of one single-family detached dwelling unit unless the City determines that the project may result in the discharge of significant levels of a pollutant into the storm drain system. However, there are two types of projects – Priority Projects and Non-Priority Projects – having different requirements for the BMPs implemented.
When should I prepare and submit my WQMP?
Since the WQMP may affect site layout and drainage design, the WQMP should be prepared as early in the planning and permitting process as is feasible, and should be refined as the project planning and design progresses. A Preliminary WQMP is submitted to the Planning Department during the filing process for Tentative Tract Map, Tentative Parcel Map, and Conditional Use Permitting. A Final WQMP must be approved by the City of Yorba Linda prior to issuance of building and grading permits.
How do I prepare a WQMP?
An informational package, including instructions and guidelines on producing a WQMP, is available upon request. A WQMP must be based upon the Orange County Model WQMP, which can be found at the following website:

PREPARING A WATER QUALITY MANAGEMENT PLAN (WQMP)
Guidance Manual
1.0 INTRODUCTION
All new development and redevelopment projects, with the exception of the construction of a singlefamily detached dwelling unit, require the submittal of a Water Quality Management Plan (WQMP). A Project WQMP is a plan for managing the quality of storm water or urban runoff that flows from a developed site after construction is completed and the facilities or structures are occupied and/or operational. Final Project WQMPs must be approved prior to issuance of building and grading permits.
This guidance document has been prepared for project applicants to outline the requirements for submitting a Project-specific Water Quality Management Plan (WQMP). The Project WQMP must be approved prior to the issuance of building or grading permits. A WQMP Template is available which provides the required structure, format, and content that must be included in a Project WQMP. If the WQMP is missing any information, it must be revised and re-submitted for approval. A copy of the WQMP Template is included with this guidance as Appendix A. The Model WQMP is available online at:
http://www.ocwatersheds.com/StormWater/documents_damp_section7.asp Project WQMPs may be submitted as “Preliminary” during the land use entitlement phase with the content and level of detail reflecting what is known or contemplated at the time project approval is sought. In any case, prior to issuance of grading or building permits, the project applicant must submit the Final Project WQMP for review and approval.
An approved Project WQMP must be implemented for the life of the project. The Project WQMP continues with the property after the completion of construction. The City of Yorba Linda requires a Notice of Transfer Responsibility Form to notify the City that a change of ownership has occurred and to notify the new owner of the responsibility for implementation of the Project WQMP. Additionally, Project WQMPs must be amended to reflect up-to-date conditions on the site consistent with the current Orange County DAMP.
2.0 REQUIREMENTS FOR DEVELOPMENT PROJECTS
Step 1 – Identify Project Type
The WQMP preparer must first identify whether the proposed project is a Priority Project or a Non Priority Project. A project is a Priority Project if it includes any of the project features listed in the following table.
If none of the features listed are included in the proposed project, the project is a Non-Priority Project.
Prepared by Fuscoe Engineering, Inc. SEPTEMBER 1, 2005
CITY OF YORBA LINDA
Is the Project: YES NO
1. Residential development of 10 units or more
2. Commercial and industrial development greater than 100,000 square feet including parking area
3. Automotive repair shops (SIC codes 5013, 5014, 5541, 7532-7534, and 7536-7539)
4. Restaurants where the land area of development is 5,000 square feet or more including parking area (SIC code 5812)
5. Hillside developments on 10,000 square feet or more, which are located on areas with known erosive soil conditions or where natural slope is twenty-five percent or more
6. Impervious surface of 2,500 square feet or more located within, directly adjacent to (within 200 feet), or discharging directly to receiving waters within Environmentally Sensitive Areas**
7. Parking Lots 5,000 square feet or more, or with 15 parking spaces or more, and potentially exposed to urban storm water runoff
8. All Significant Redevelopment projects, where Significant Redevelopment is defined as the addition of 5,000 or more square feet of impervious surface on an already developed site. Significant Redevelopment includes, but is not limited to:
Expansion of a building footprint.
Addition of a building and/or structure.
Addition of an impervious surface, such as construction of a new parking lot, which is not part of a routine maintenance activity.
Replacement of impervious surfaces, buildings and/or structures when 5,000 or more square feet of soil is exposed during replacement construction.
Replacement does not include routine maintenance activities, trenching and resurfacing associated with utility work, resurfacing and reconfiguring the surface of parking lots (unless 5,000 or more square feet of impervious surface is added to the existing parking lot area) or reconfiguration of pedestrian ramps and replacement of damaged pavement.
** These areas are shown on maps that are available upon request or can be found at:
www.ocwatersheds.com/StormWater/documents_damp_section7.asp.
If the project is determined to be a Priority Project, the Project WQMP must:
Incorporate all Source Control Best Management Practices (BMPs), unless not applicable to the project due to project characteristics.
Incorporate Site Design BMPs, as appropriate, and describe how the Site Design BMPs have been incorporated in the project.
Either incorporate Treatment Control BMPs, by including a selection of such BMPs into the project design, or participate in or contribute to an acceptable regional or watershed-based program.
Note: If only a specific project feature falls into one of the above listed Priority Project categories, then only that feature is subject to the Priority Project WQMP requirements. For example, in a situation where there is a 6,000 square foot parking lot for an industrial development that is less than 100,000 square feet, only the parking lot is subject to the Priority Project requirements.
If the project is determined to be a Non-Priority Project, the Project WQMP must:
Prepared by Fuscoe Engineering, Inc. SEPTEMBER 1, 2005
CITY OF YORBA LINDA
Incorporate all Source Control BMPs (routine structural and routine non-structural), unless not applicable to the project due to project characteristics. Provide reasonable and accurate reasons for not including applicable Source Control BMPs.
Incorporate Site Design BMPs, as appropriate, and describe how the Site Design BMPs have been reflected in the project.
Step 2 – Identify Pollutants of Concern
If the proposed project is determined to be a Priority Project, the WQMP must identify anticipated pollutants of concern associated with the project’s land uses and the type of development. These pollutants will be addressed by the project’s Treatment Control BMPs. The following table, derived from the Model WQMP, summarizes the categories of typical land use or project features of concern and the general pollutant categories associated with them. Refer to the Model WQMP for further details and descriptions of the general pollutant categories.
Note: This step is not necessary for Non-Priority Projects.

Prepared by Fuscoe Engineering, Inc. SEPTEMBER 1, 2005
CITY OF YORBA LINDA
Additional considerations should be made when identifying the pollutants of concern, such as the existing soil and water quality conditions as a result of past land uses, and the pollutants of concern associated with the project’s receiving water body. To identify the pollutants of concern to the project’s receiving waters, the WQMP preparer must, at a minimum, do the following:
(1) For each of the proposed project discharge points, identify the receiving water for each point of discharge and all water bodies downstream of the receiving water as identified in the most recent version of the Water Quality Control Plan (Basin Plan) for the Santa Ana Basin – see www.waterboards.ca.gov/santaana/html/basin_plan.html
(2) Identify known pollutant impairments of the downstream receiving waters as included in the most recent list of Clean Water Act Section 303(d) impaired water bodies – see www.waterboards.ca.gov/tmdl/303d_lists.html
(3) Identify if the impaired water bodies have established Total Maximum Daily Loads (TMDLs) – see www.waterboards.ca.gov/tmdl/tmdl.html
Primary Pollutants of Concern are those pollutants that have been identified as anticipated from the project that are also identified as causing impairments of the project receiving waters. These pollutants should be addressed by the project’s Treatment Control BMPs. Other Pollutants of Concern are those pollutants anticipated from the project that have not been identified as causing impairment of project receiving waters.
Step 3 – Identify Hydrology Conditions of Concern
If the project is determined to be a Priority Project, the WQMP preparer must identify hydrologic conditions of concern that will be managed by the BMPs set forth in the Project WQMP. Common impacts to hydrologic conditions resulting from development include increased runoff volume and velocity; reduced infiltration; increased flow frequency, duration, and peaks; faster time to reach peak flow; and water quality degradation. These changes have the potential to permanently impact downstream channels and habitat integrity. If a downstream impact is discovered or identified, a Drainage Study will be required to demonstrate the mitigation measures required to minimize these hydrologic conditions of concern.
This step is not necessary for Non-Priority Projects.
3.0 WQMP PREPARATION
Once the necessary project information has been identified and/or obtained, the WQMP preparer should create the document in the format described in the WQMP Template document and should include all of the required information. The Preparer’s WQMP checklist included as Appendix B must be used to ensure that all of the necessary information has been addressed in the Project WQMP.
The following sections highlight some of the requirements for preparing a Project WQMP. Refer to the Model WQMP and WQMP Template for detailed information on the specific requirements.

A complete copy of the final Resolution of Approval (that is, the conditions of approval) should be included as an appendix to the Project WQMP.
WQMP Section II, Project Description
The Project Description should completely and accurately describe the proposed project, including the size, where facilities and structures will be located, what activities will be conducted and where, what kinds of materials will be used and/or stored, how and where materials will be delivered, what kinds of wastes will be generated, what BMPs are being implemented, etc. Refer to the Model WQMP for a detailed list of all items to be covered in the Project Description section.
WQMP Section III, Site Description
The Site Description must describe the project area and surrounding areas in sufficient detail to allow the project location to be plotted on a map. In this section, provide the general and specific location, site address, and size (acreage to the nearest 1/10 acre), zoning or land use designation, soil types, site drainage (pre- and post-development conditions, watershed, pollutants of concern, and describe the preand post-development imperviousness conditions. Refer to the Model WQMP for a detailed list of all items to be covered in the Site Description section.
WQMP Section IV, Best Management Practices
There are three types of BMPs for a Project WQMP:
1) Site Design BMPs – Project features that are designed or incorporated into a project to reduce the increase in runoff from the development of the project site. Examples are use of porous asphalt or pavers, minimizing the use of decorative concrete, and directing roof drains to landscaped area.
2) Source Control BMPs – Activities or structures aimed at eliminating or minimizing contact between pollutant sources and rainfall or runoff. Examples are education, sweeping, litter collection, canopies over fueling islands, awnings or tarps to cover materials stored outdoors. 3) Treatment Control BMPs – Engineered devices or systems incorporated into the project’s drainage system to remove pollutants from runoff before the runoff leaves the project site.
Examples are vegetated swales, infiltration trenches, detention/retention basins, catch basin filters, and vortex separators.
These BMPs will be used by property owners, facility operators, tenants, facility employees, maintenance contractors, etc. to prevent and minimize water pollution that can be caused by storm water or urban runoff. As such, the description of each BMP should reflect the nature of the activities to be conducted, locations, and how they will be implemented specific to the proposed project.
Prepared by Fuscoe Engineering, Inc. SEPTEMBER 1, 2005
CITY OF YORBA LINDA
If the project has been identified as a Priority Project, the Project WQMP must incorporate:
Site Design BMPs;
Source Control BMPs (routine non-structural and routine structural); Treatment Control BMPs (or participation in a regional or watershed program).
Non-Priority Projects must incorporate:
Site Design BMPs,
Source Control BMPs (routine non-structural and routine structural).
Note: Non-Priority Projects should consider incorporating Treatment Control BMPs into the proposed project.
WQMP Section IV.1, Site Design BMPs
Site Design BMPs are project features that are designed or incorporated into a project to reduce the increase in runoff from the development of the project site. Site Design BMPs can also control or reduce peak storm water runoff flow rates and reduce downstream erosion rates to protect stream habitat. Site Design BMPs include:
Minimize Impervious Areas – This concept includes, but is not limited to: minimizing impervious footprints, constructing streets and sidewalks to the minimum widths necessary, constructing onsite ponding areas, and using pervious pavements. Minimize Directly Connected Impervious Areas – This concept includes, but is not limited to:
draining impervious surfaces such as sidewalks and streets to pervious areas such as adjacent landscaping, use of rural swale systems, and vegetated swale systems. Conserve Natural Areas – This can be achieved by concentrating or clustering development on the least environmentally sensitive portions of a site while leaving the remaining land in a natural, undisturbed condition.
Create Reduced or “Zero Discharge” Areas – such as constructing onsite ponding areas or retention facilities to increase opportunities for infiltration.
These concepts are described further in pages 7.II-15 through 7.II-18 in the Model WQMP.
Within the text of the WQMP, describe how Site Design BMPs were considered and incorporated into the proposed project. Indicate in the table the type of Site Design BMPs included in the proposed project plans. If specific Site Design BMPs were not included in the project plans, the reasons for such must be stated as well.
Section IV.2: Source Control BMPs
Source Control BMPs are activities or structures aimed at eliminating or minimizing the contact between pollutant sources and rainfall or runoff. Source Control BMPs can be divided into three categories:
routine non-structural BMPs, routine structural BMPs, and BMPs for individual project features.
Routine Source Control BMPs (routine non-structural BMPs, routine structural BMPs, and BMPs for individual categories/project features) are required to be incorporated in all new development and Prepared by Fuscoe Engineering, Inc. SEPTEMBER 1, 2005
CITY OF YORBA LINDA
redevelopment projects, unless they do not apply due to the project features and characteristics. This includes both Priority Projects and Non-Priority Projects.
Section IV.2.1, Routine Non-Structural BMPs
The WQMP must include descriptions of how each included BMP will be implemented by the proposed project. Descriptions should include implementation procedures, locations, frequency, and the entity or person responsible for the BMP. For those designated as not applicable, briefly state the reason why in the appropriate column.
N1, Education for Property Owners, Tenants and Occupants Materials (brochures, booklets, operating manuals, etc.) applicable and appropriate for educating and/or training property owners, tenants, facility operators, employees, and others must be provided in Section VII of the Project WQMP. At a minimum, the WQMP preparer must review and consider the educational materials available through the following websites:

The Project WQMP must identify the specific Conditions, Covenants, and Restrictions (CC&Rs), lease terms, or other policies that are or will be applicable to a project in restricting or prohibiting activities once the project is operational. The Project WQMP must also identify the entity or person that will enforce activity prohibitions or restrictions.
Some examples of activity restrictions that promote water quality protection are:
Prohibit discharges of fertilizer, pesticides, or animal wastes to streets or storm drains. Prohibit connections of pool/spa drains to streets or storm drains. Prohibit the washing kitchen wastes or kitchen equipment (restaurant, fast food, grocery store deli, bakery, etc.) to storm water drainage features.
Prohibit vehicle washing, maintenance, or repair on the premises or restrict those activities to designated areas.
N3, Common Area Landscape Management
The Project WQMP must identify the specific procedures that will be implemented to manage landscaped common areas, comply with the applicable water conservation ordinance (City of Yorba Linda Guidelines and Specifications for Landscape Development, Ordinance No. 2004-884), and to properly manage the use of fertilizers and pesticides. Additionally, if the project will utilize reclaimed water for irrigation, the special conditions that apply to the use of reclaimed water must be described in this section.
N4, BMP Maintenance
Detailed discussions of the maintenance for each BMP should be discussed in a separate section of the BMP (WQMP Section V). For the purpose of this section, a reference to that section should be stated. An example statement is, “BMP maintenance, implementation schedules, and responsible parties are included with each specific BMP narrative in Section X of this report.” N5, Compliance with Title 22 California Code of Regulations If no hazardous wastes will be generated during operation of a project, that fact should be provided as the “brief reason”. However, if hazardous wastes will be generated and/or stored, the Project WQMP must describe how a project will comply with local and state requirements, what type of waste will be Prepared by Fuscoe Engineering, Inc. SEPTEMBER 1, 2005
CITY OF YORBA LINDA
generated, how it will be stored and disposed, and who will be responsible for maintaining records. A general statement that the facility will comply with the requirements is not sufficient.
N6, Local Water Quality Permit Compliance
At this time, neither the County of Orange nor the City of Yorba Linda issue water quality permits.
N7, Spill Contingency Plan
Typically spill contingency plans apply to those facilities having bulk liquid storage such as aboveground or underground storage tanks, pipelines, storage of multiple 55-gallon drums, fueling pumps, etc.
Where applicable, a Project WQMP must describe the types and quantities of containment and cleanup materials that will be available onsite and where; and describe agency notification containment, cleanup, and disposal procedures as well as applicable reporting requirements.
N8, Underground Storage Tank Compliance
If the proposed project includes underground storage tanks, the Project WQMP must describe how the facility will comply with State regulations for underground storage tanks. Information regarding California’s underground storage tank regulations can be found at www.waterboards.ca.gov/ust/. A general statement that the facility will comply with the requirements is not sufficient.
N9, Hazardous Materials Disclosure Compliance
If the proposed project (post-construction) will include the storage and use of hazardous materials, the Project WQMP must provide guidance to the owner, operators and employees regarding compliance with hazardous materials disclosure regulations. If hazardous materials will be stored or used, the Project WQMP must identify the person/entity responsible for preparation of the “Chemical Inventory and Business Emergency Plan” and the administering agency for hazardous materials disclosure. More information regarding compliance with hazardous materials disclosure regulations can be found at www.ocfa.org/business/hmss/rmppage2.htm. A general statement that the facility will comply with the requirements is not sufficient.
N10, Uniform Fire Code Implementation
Article 80 of the Uniform Fire Code addresses the proper management of hazardous materials and emergency response plans. The Project WQMP must provide guidance to the owner, operators and employees in the compliance with Article 80 of the Uniform Fire Code enforced by the applicable fire protection agency. More information regarding compliance with Article 80 can be found at www.ocfa.org/business/hmss/index.htm. A general statement that the facility will comply with the requirements is not sufficient.
N11, Common Area Litter Control
Projects are required to implement trash management and litter control procedures in the common areas.
The Project WQMP must describe the common area litter control measures including where trash receptacles will be provided for public use, how frequently trash receptacles will they be emptied, inspection of common areas for litter, noting trash disposal violations by tenants/homeowners or businesses, reporting violations to the owner/HOA/POA for investigation, and identifying the person or entity responsible for implementation.
N12, Employee Training
This BMP refers to the education program (see N1), as it would apply to employees of industrial or commercial facilities. In addition to the information required by BMP N1, if the proposed project is being Prepared by Fuscoe Engineering, Inc. SEPTEMBER 1, 2005
CITY OF YORBA LINDA
constructed for an unspecified use, the developer/owner must describe how this education requirement will be met by future operators/owners.
N13, Housekeeping of Loading Docks
Loading docks and shipping/receiving areas should be kept in a clean and orderly condition through regular sweeping and litter control and immediate cleanup of spills and broken containers. Cleanup procedures should minimize or eliminate the use of water. If washdown water is used, it must be contained, collected, and disposed of in an approved manner and not discharged to the storm drain system.
N14, Common Area Catch Basin Inspection
The owner is required to have at least 80% of drainage facilities inspected, cleaned and maintained on an annual basis with 100% of the facilities included in a 2-year period. Cleaning should take place in the late summer/early fall prior to the start of the rainy season (October 1). Drainage facilities include catch basins (storm drain inlets) detention basins, sediment basins, open channels, and lift stations.
N15, Street Sweeping Private Streets and Parking Lots
At a minimum, streets and parking lots are required to be swept prior to the rainy season (October 1), in late summer or early fall. The Project WQMP must describe the manner and frequency of private street and parking lot cleaning and proper disposal of the accumulated sweeping waste.
Note: There is no BMP with the designation N16.
N17, Retail Gasoline Outlets
Retail gasoline outlets are required to follow operations and maintenance BMPs described in the California Stormwater Quality Association (CASQA) Best Management Practice Guide for Retail Gasoline Outlets. This document may be obtained by downloading from the CASQA website (www.casqa.org) under “Publications and Work Products”. Each BMP listed in the Guide for Retail Gasoline Outlets for an on-site activity/area must be implemented.
Section IV.2.2, Routine Structural BMPs
The WQMP must include descriptions of how each included BMP will be implemented by the proposed project. Descriptions should include implementation procedures, locations, frequency, and the entity or person responsible for the BMP. For those designated as not applicable, briefly state the reason why in the appropriate column.
Provide Storm Drain System Stenciling and Signage.
Storm drain stencils are typically placed directly adjacent to storm drain inlets and catch basins, and contain either a graphical icon and/or a brief statement such as “NO DUMPING-DRAINS TO RIVER” that warns against dumping wastes into the municipal storm drain system.
Design Outdoor Material Storage Areas to Reduce Pollutant Introduction If a proposed project includes outdoor storage areas for materials the following BMPs are required:
Hazardous materials must be placed in an enclosure such as a cabinet or shed or must be protected by secondary containment structures such as berms, dikes, or curbs, and must be paved and sufficiently impervious to prevent leaks and spills from impacting soils. The storage area must have a roof or awning to minimize direct contact with rainwater.
Prepared by Fuscoe Engineering, Inc. SEPTEMBER 1, 2005
CITY OF YORBA LINDA
Any storm water retained within the containment structure must not be discharged to the street or storm drain system.
Use Efficient Irrigation Systems and Landscape Design
Projects must be designed such that the timing and application methods of irrigation water minimizes runoff into the storm drain system. The methods listed on pages 7.II-22 and 7.II-23 of the Model WQMP for reducing excessive irrigation runoff must be considered.
Protect Slopes and Channels
Project plans must include BMPs to decrease the potential for erosion of slopes and downstream drainages or channels. The design principals for the protection of slopes and channels found on pages
7.II-23 and 7.II-24 in the Model WQMP must be incorporated and implemented were applicable.
Requirements Applicable to Individual Features
All projects must incorporate each of the individual project feature requirements that are applicable to the proposed project. These project features include loading docks, maintenance bays, vehicle wash areas, outdoor processing areas, equipment wash areas, fueling areas, hillside landscaping, wash water control for food preparation areas, and community car wash racks. Table 7.II 4 in the Model WQMP must be used to identify the structural BMPs that must be incorporated into the project plans. Pages 7.II26 through 7.II-29 of the Model WQMP provide specific requirements for each of the BMPs. Guidance for the owner, operators and/or employees in the proper maintenance of each measure, the schedule of inspection and maintenance, and the responsible party must be provided.
Section IV.3: Treatment Control BMPs
Priority Projects are required to incorporate Treatment Control BMPs into project plans. Non-Priority Projects should consider implementing Treatment Control BMPs into their project plans to minimize impacts to water quality from urban runoff.
Treatment Control BMPs must be designed to minimize the impacts of urban runoff by capturing and treating the amount of runoff produced from a 24-hour 85th percentile storm. Based on historical rainfall data fro north Orange County, this is generally equivalent to the amount of runoff generated from the first 0.85 inches of rainfall in the City of Yorba Linda.
There are two generally accepted methods to demonstrate that the Treatment Control BMPs are adequately designed to meet this criterion, by calculating the Stormwater Quality Design Volume (SQDV) or the Stormwater Quality Design Flow (SQDF) captured and/or treated by the proposed BMP. These methods are described further in Appendix C. Further information is provided in pages 7.II-33 through
7.II1-40 of the Model WQMP.
The table must indicate all Treatment Control BMPs to be incorporated in the project. Following Table 4 in the Project WQMP, provide descriptions of each Treatment Control BMP to be incorporated in the project plans. This includes an overview of the BMP implemented, proposed location(s), preliminary design calculations for sizing BMPs (i.e. SQDV or SQDF), and pollutants addressed/treated by each BMP. [insert pollutants table reference] The location of each Treatment Control BMP must also be shown on the WQMP Site Plan.

APPENDIX C
Calculating Storm Water Runoff Treatment Design Criteria New developments and redevelopments must be able to capture and treat the amount of runoff generated from the first 0.85 inches of rainfall on the project site. Treatment Control BMPs, such as sedimentation basins and manufactured treatment devices (water quality/storm drain inserts), must be designed to meet this criterion. There are two generally accepted methods to demonstrate this: 1) Volume-Based BMPs (water quality basins, infiltration trenches) and 2) Flow-Based BMPs (vegetated swales, storm drain inserts).
VOLUME-BASED BMPS.
The following equation determines the volume of runoff the post-construction BMPs must be able to mitigate. This volume is termed Stormwater Quality Design Volume, or SQDV.
SQDV = (C ¾ I ¾ A) ¾ (1 ft ÷ 12 inches) ¾ (43,560 ft2 ÷ 1 acre ) Where: SQDV = storm water quality design volume (ft3
)
C = coefficient of runoff of the treatment area (see following page) I = 0.85 inches (24-hour 85th percentile rainfall)
A = total area to be treated (acres)
FLOW-BASED BMPS.
The following equation determines the flow rate capacity that the post-construction BMPs must be able to mitigate. This volume is termed Stormwater Quality Design Flow, or SQDF.
SQDF = (C ¾ I ¾ A) ¾ (1.008333 ft3
per hour ÷ acre-inches-seconds )
Where: SQDF = storm water quality design volume (cubic feet per second [cfs]) C = coefficient of runoff of the treatment area (see following page) I = 0.2 inches / hour (rainfall intensity)
A = total area to be treated (acres)
For more information, refer to Attachment A of the Model WQMP.

1 Detention and retention areas incorporated into landscape design provide areas for retaining and detaining stormwater flows, resulting in lower runoff rates and reductions in volume due to limited infiltration and evaporation. Such Site Design BMPs may reduce the size of Treatment Control BMPs.
2 The “C Factor” is a representation of the ability of a surface to produce runoff. Surfaces that produce higher volumes of runoff are represented by higher C Factors. By incorporating more pervious, lower C Factor surfaces into a development, lower volumes of runoff will be produced. Lower volumes and rates of runoff translate directly to lowering treatment requirements.

permit(s) have expired or have been closed, and projects that have been completed, will be removed from the inventory. New projects will also be added to the inventory as they are initiated. A GIS map showing the location of the construction projects inventoried and their proximity to environmentally sensitive areas has also been included in Exhibit A-8.I.
A-8.3 Prioritization of Construction Sites
After the inventory is compiled, construction projects will be prioritized into high, medium, or low categories, based on the threat to water quality and the procedures set forth in DAMP Section 8.4.3. Priorities will at a minimum be updated annually in conjunction with the annual update of the inventory.
A-8.4 BMPs for Construction Projects
All construction projects, regardless of size or priority, are required to implement BMPs to prevent discharges into the storm drain system or watercourses. DAMP Section 8.4.4.1 specifies minimum requirements for all projects and specific site management requirements for high and medium priority projects.
All private and public works construction projects are required, at a minimum, to implement and be protected by an effective combination of erosion and sediment controls and waste and materials management BMPs. The minimum requirements are summarized in Table 8-6 of the DAMP (also shown below). These minimum requirements are conveyed to construction contractors as part of the permit conditions and plan notes.
Table A-8.1
Minimum Requirements for All Construction Sites
CATEGORY MINIMUM REQUIREMENTS
Erosion and Sediment Control Sediments from areas disturbed by construction shall be retained on site using an effective combination of erosion and sediment controls to the maximum extent practicable, and stockpiles of soil shall be properly contained to minimize sediment transport from the site to streets, drainage facilities or adjacent properties via runoff, vehicle tracking, or wind.
Waste and Materials Management
Control
Construction-related materials, wastes, spills or residues shall be retained on site to minimize transport from the site to streets, drainage facilities, or adjoining property by wind or runoff.

Sandbag Velocity Reducer (No. 1328)
Temporary Drainage Inlet (No. 1330)
A-8.5 Documentation Requirements
The City of Yorba Linda has adopted the documentation requirements provided in DAMP Section 8.4.5. These requirements apply equally to private development and public works projects.
Requirements for General Permit Sites
Construction sites that are subject to the General Permit are required to prepare and implement a Storm Water Pollution Prevention Plan (SWPPP) meeting the requirements of the General Permit. A Model SWPPP Template has been included as Exhibit A-8.IV as a guide for the information that should be included in a SWPPP.
Private Construction Projects Covered by the General Permit The following bullets describe the process that is followed by a private construction project:
The project owner, developer or contractor is responsible for preparing the Notice of Intent (NOI), which must be signed by the owner or person delegated authority and submitted to the State Water Resources Control Board (SWRCB). Before issuing a grading or building permit, the city will require proof of General Permit coverage (See conditions of approval Section A-7.5.3).
Once the project owner, developer or contractor receives a grading or building permit (if applicable), the SWPPP must be prepared by the owner, developer or contractor, and signed by the responsible party and must be implemented year-round throughout the duration of
SECTION A-8, CONSTRUCTION
City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) A-8-6
the project’s construction. Inspector(s) may choose to use the SWPPP as a tool for on-site inspections.
The city will inspect and enforce local permit(s) and ordinances, and will notify the Regional Board of non-compliance when the non-compliance meets the criteria of posing a threat to human or environmental health as discussed in DAMP Section 8.4.6. Once project construction is completed and the site fully complies with the final stabilization requirements of the General Permit, the owner/developer will submit a Notice of Termination (NOT) to the SWRCB.
Public Agency Construction Projects Covered by the General Permit The following bullets describe the process that is followed by a public works construction project:
The City of Yorba Linda will notify the SARWQCB via an informal Notification of Construction Activity.
The SWPPP will be prepared by the City of Yorba Linda or its engineer/contractor, before the contractor is allowed to start construction activities. It is important to note that City Staff is not responsible for enforcing the SWPPP, these are responsibilities of the SARWQCB; but inspectors are required to become familiar with the SWPPP, as it is part of the contract documents.
During construction, the City of Yorba Linda will inspect and enforce the contract documents and will notify the appropriate SARWQCB when non-compliance meets the criteria of posing a threat to human or environmental health as discussed in Section 8.4.6 of the DAMP.
Once the project is completed, the City of Yorba Linda will inform the SARWQCB of the project’s completion.
Requirements for Other Sites
Private Construction Projects Not Covered by the General Permit Private construction projects not covered by the General Permit, but covered under a grading permit, are required to develop Erosion and Sediment Control Plans (ESCPs). These ESCPs must show proposed locations of the erosion and sediment control BMPs that will be implemented during the construction project to comply with the minimum requirements listed in Table A-8.1.
Public Works Construction Projects Not Covered by the General Permit Public agency construction projects not covered by the General Permit are required by DAMP Section 8.4 to comply with appropriate pollution prevention control practices in accordance with the current edition of the “Green Book” Standard Specifications for Public Works
SECTION A-8, CONSTRUCTION
City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) A-8-7
Construction and the provisions of Section A-8, and shall develop and implement ESCPs. Low priority construction sites shall meet the minimum requirements listed in Table 8-6 of Section
8.4.4 of the DAMP.
A-8.6 Municipal Inspection Requirements of Construction Sites and Reporting Requirements
Inspection Responsibilities
The City of Yorba Linda will perform inspections of construction sites to verify that the requirements in DAMP Section 8.4.6 are being implemented and maintained, that they appropriately comply with local permits and ordinances and the General Permit (for public works projects covered by the General Permit), and that they continue to protect water quality.
Construction sites are inspected, according to the established priority, until construction activity is complete.
Inspection Frequencies
The City of Yorba Linda will inspect construction sites based upon the priority of the project.
The frequency of construction site inspections is shown in Table A-8.3:
Table A-8.3
Construction Site
Priority
Rainy Season
(October 1 - April 30)
Dry Season
(May 1 - September 30)
HIGH Once per month As needed
MEDIUM Twice during the season As needed
LOW Once during the season As needed
Inspection Documentation Procedures
The City of Yorba Linda’s construction site inspection checklist is included in Exhibit A-8.V.
Records of all inspections and non-compliance reporting will be retained for a period of at least three years.
Enforcement Actions
Enforcement of construction projects will be undertaken by the City of Yorba Linda’s inspectors and/or other staff who possess internal enforcement authority through established policies and procedures. Threat to water quality will be assessed by inspectors for construction site runoff that will not be reasonably controlled by the BMPs in place or if a failure of BMPs is resulting in the release of sediments or other pollutants. Violations observed will be documented by the inspectors.
SECTION A-8, CONSTRUCTION
City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) A-8-8
If a significant and/or immediate threat to water quality is observed by an inspector, action will be taken to require the developer/contractor to immediately cease the discharge. Table A-8.4 outlines the City of Yorba Linda’s enforcement steps that will be taken by inspectors for private construction projects and for public works construction projects. Depending on the violation, the inspector may choose to utilize contract language, a local permit, the grading ordinance or the water quality ordinance as the basis for enforcement.

As a general rule for the City, if the inspector determines that the violation is resulting in a nonsoil discharge, Code Enforcement officers are contacted to pursue appropriate enforcement action(s). Otherwise, construction site inspectors enforce violations resulting in sediment related discharges.
Non-Compliance Reporting
SECTION A-8, CONSTRUCTION
City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) A-8-9
The City of Yorba Linda will consider a site non-compliant when one or more violations of local ordinances, permits, or plans exist on the site. For the purpose of this document, such a violation shall also be considered a violation of the General Construction Permit for sites subject to those requirements. If a non-compliant private construction project meets the criteria of posing a threat to human or environmental health as discussed in Section 8.4.6 of the DAMP, then the SARWQCB will be notified as required.
Oral notification to the SARWQCB of non-compliant private construction sites that are determined to pose a threat to human or environmental health will be provided within 24-hours of the discovery of non-compliance. Such oral notification shall be followed up by a written report and submitted to the SARWQCB within 5 days of the incidence of non-compliance.
Written notification(s) will identify the type(s) of non-compliance, describe the actions necessary to achieve compliance, and include a time schedule, subject to the modifications by the SARWQCB, indicating when compliance will be achieved.
A form for evaluating the potential impacts to human or environmental health is provided in Exhibit A-8.VII .
A-8.7 Education and Training
To assist responsible municipal staff and contract staff in understanding the DAMP’s Model Construction Program, annual training sessions will be conducted. In addition to Permittee sponsored training, staff may also attend training seminars or workshops related to general water quality and stormwater management during construction, conducted by other organizations.
A-8.7.1 Training Modules
Two training modules have been prepared that cover different aspects of the Model New Development/Significant Redevelopment Program. These modules are provided in DAMP Appendix B, Section B-8.
Construction Program Management (DAMP Appendix B, Exhibit B-8.I) This training module is targeted to staff responsible for managing the NPDES program for construction and will address: the laws and regulations applicable to construction and grading activities; the connection between construction activities and water quality; inventory and prioritization of construction sites; implementation of construction site BMPs; documentation and enforcement requirements; reporting procedures for non-compliance; program effectiveness assessment; and training.
Inspecting Construction Site BMPs (DAMP Appendix B, Exhibit B-8.II) This training module is targeted to staff responsible for conducting inspections of both private and public construction sites and will address: the laws and regulations applicable to
SECTION A-8, CONSTRUCTION
City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) A-8-10
construction and grading activities; the connection between construction activities and water quality; inspection of construction site BMPs; documentation and enforcement procedures; and examples of what to look for in construction site BMPs.
A-8.8 Program Effectiveness Assessment
The overall Program Effectiveness Assessment (PEA) serves as the foundation for the submittal of the annual progress report that is submitted each year to the Principal Permittee and subsequently to the Regional Boards and serves as the basis for evaluating each municipality’s individual construction program efforts (See DAMP Appendix C, Section C-8).
The PEA allows each municipality to assess the effectiveness of their individual storm water program components including those focused on addressing stormwater and non-stormwater discharges associated with construction activity. The construction program effectiveness assessment will enable the City to evaluate the effectiveness of the local program by focusing on data collected from the inventorying, prioritization, inspection and enforcement of construction projects as well as training records.

The existing development component of this plan is composed of the following elements:
1. Section A-9.1, Industrial Program
2. Section A-9.2, Commercial Program
3. Section A-9.3, Residential Program
A-9.1 Industrial Program
The program described in this section was developed pursuant to Sections IX of the Santa Ana Order and Section 9.0 of the DAMP
A-9.1.1 Pollution Prevention and Program Administration The City of Yorba Linda’s Industrial Component includes specifications for pollutionprevention methods for industrial areas and activities located within the City. Specific pollution prevention practices that are generally recognized in each Discharger’s industry or business, or for that Discharger’s activity, as being effective and economically advantageous, were certified by the City (see Section A-9.1.5). The City through an inspection program summarized in Section A-9.1.6 will verify implementation of pollution-prevention methods by industries. Inspectors will use a checklist for their inspections, which will also include appropriate pollution-prevention methods.
The City of Yorba Linda will implement the industrial program through various City departments as illustrated in Figure A-9.1 below.

City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) 3
911 calls that may involve industrial discharges, spills, chemical emergencies, accidents, etc.
Refers problems associated with non-storm water discharges to City for enforcement.
A-9.1.3 Source Identification
The City of Yorba Linda is required to develop, and update annually, a watershed-based inventory of all industrial sites within its jurisdiction, regardless of site ownership. The process for conducting the inventory was explained in the Section 9.4.3 of the DAMP. The components that comprise the inventory include:
All industrial facilities located within the City’s jurisdiction Watersheds where each industrial facility is located
Identified potential pollutants and activities with the potential to discharge pollutants Identified industrial discharges into, or adjacent to, an Area of Special Biological Significance (ASBS)
The City’s inventory database includes the following information about each identified industry within the City’s jurisdiction:
Business Name;
Physical Address Information;
Mailing Address Information;
SIC Code;
Commercial-Specific Information;
Watershed;
Proximity to ESA/ASBS;
Comments/Notes.
The current watershed-based inventory of industrial facilities within the city’s jurisdiction is provided in Exhibit A-9.I.
A-9.1.4 Prioritization for Inspection
To comply with these permit requirements, the City of Yorba Linda prioritized industrial sites and sources as high, medium, and low, based on their respective threat to water quality and the procedures set forth in DAMP Section 9.4.3.2. A classification of High Priority indicates that the facility contains a site or sources with a high potential threat to the water quality. Permit requirements classify some industries as mandatory High Priority facilities. For industries that were not pre-classified, the prioritization process, which is consistent with permit requirements as outlined in Section 9.4.3.2 of the DAMP, consisted of assigning a score to each facility based on the following factors:
Type of Activity
Material Used
Waste Generated
Pollutant Discharge Potential
Non-Storm Water Discharges
SECTION A-9, EXISTING DEVELOPMENT
City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) 4
Size of Facility
Proximity to an Environmentally Sensitive Water Body
Industries that received a score of greater than or equal to 25 were ranked as High Priority, those with a score below 25 and greater than 15 were ranked as Medium Priority, and those with a score less than or equal to 15 were ranked as low priority.
A-9.1.5 BMP Implementation
The City of Yorba Linda has designated a minimum set of activity-specific BMPs for industrial facilities, as set forth in Section 9.4 of the DAMP and modified according to City requirements.
The City has designated the BMPs shown in Table A-9.2 below that are appropriate to prevent or mitigate pollution generated from the specific activities at each site. The corresponding fact sheets are presented in Exhibit A-9.II.

The City encourages the implementation of the designated BMPs at each industrial facility based on site-specific conditions in order to limit that facility’s impact upon receiving water quality. If particular BMPs are infeasible at any specific site, other equivalent BMPs will be implemented.
A-9.1.6 Inspection, Monitoring and Enforcement
A-9.1.6.1 Inspection
Inspection frequencies for industrial facilities are based on permit requirements and the priority ranking assigned to each facility as described in Section A-9.1.3. A summary of required inspection frequencies based on priority ranking is shown in Table A-9.3. In addition to the inspection frequencies described, the City will also investigate all complaints of illegal discharges from industrial facilities made by the public or by another agency or those violations arising from the results or dry-weather field screening or analytical monitoring program. In the event that a site is found to be non-compliant, inspection frequency will be increased to, at a minimum, once per month. Once a facility has been brought into compliance, an inspection frequency of once every four months will be maintained for the next calendar year following the date at which the facility is deemed to be in compliance.

1 – Bi-annually (once every two years) for any site that the City certifies all of the following in a written statement to the RWQCB:
a. City has record of the industrial facility's Waste Discharge Identification Number (WDID#) documenting facility's coverage under the statewide General Industrial Permit; and
b. City has reviewed the Industrial facility's Storm Water Pollution Prevention Plan (SWPPP); and
c. City finds SWPPP to be in compliance with all local ordinances, permits, and plans; and
d. City finds that the SWPPP is being properly implemented on site. 2 – At least once per permit cycle (every 5 years) is recommended The City of Yorba Linda will inspect industrial facilities to determine if they are in compliance with City ordinances, to review BMP implementation, to assess BMP effectiveness and to verify inventory information used for facility prioritization. Such inspections include review of:
Material and waste handling and storage practices,
Pollution control BMP implementation and maintenance, and Evidence of past or present unauthorized, non-storm water discharges.
The inspection procedures and inspection form provided in Exhibit A-9.III will be used and provides a series of questions about specific activities taking place at a facility, as well as a list of suggested corrective actions that can be implemented should a problem be found.
In general the City of Yorba Linda will conduct one of two types of inspections:
Compliance Inspections
Initial compliance inspections will be announced so that the inspector can meet with responsible facility official(s) (e.g., owner, superintendent, compliance manager, engineering consultant, etc.) in order to provide more efficient communication of the storm water requirements and inspection goals. The inspection will focus on current facility operations and activities, BMPs currently in use, and the effectiveness of those BMPs. This inspection will also focus on verifying inventory spreadsheet information and, whenever possible, provide outreach education to facility staff. All re-occurring compliance inspection will cover the same information as an initial compliance inspection, but will typically be unannounced in order to verify compliance and that BMPs are being effectively implemented.
Follow-up Inspections
For those facilities deemed to be non-compliant, the Permittee will perform compliance inspections once a month until said facilities are shown to be complaint, and then once every four months for a full calendar year after the facility achieves compliance.
Generally, these inspection will be similar to Advisory Inspection except that a) they will focus primarily on areas where a facility was deemed to be non-compliant and b) the inspections may be announced or unannounced, depending on which course of action the Permittee deems will be most conducive to continued facility compliance.
Should an inspected site demonstrate non-compliance, the City will coordinate the notification of appropriate agencies. An incident or practice of non-compliance that requires a hazardous materials emergency response will be considered a threat to human or environmental health
SECTION A-9, EXISTING DEVELOPMENT
City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) 7
and will be reported to the RWQCB and to appropriate hazardous waste management agencies.
The City will provide oral notification to the RWQCB within 24 hours of the discovery of a noncompliant site meeting the criteria listed below. This will also be followed by written notification within 5 days of the discovery.
Criteria to be used to determine whether an event of non-compliance poses a threat to human or environmental health include the following:
The event poses a significant or imminent threat to the quality of surface or ground waters and/or their beneficial uses.
The event results in a spill or discharge of hazardous materials in excess of reportable quantities (as listed in 40 CFR Part 117 or 302).
The event results in a spill or discharge of hazardous materials requiring a hazardous materials emergency response (see Section 10 of the DAMP).
A-9.1.6.2 Enforcement
City inspectors with enforcement authority will issue enforcement actions to industrial facility owners and operators determined to be out of compliance as detailed in DAMP Section 9.4.5.
The inspectors will document each observed violation. Depending on the severity of the violation, enforcement actions can range from a verbal warning to civil or criminal court actions with monetary fines.
If a City inspector observes a significant and/or immediate threat to water quality, action will be taken to require the facility owner and/or operator to immediately cease the discharge.
The enforcement mechanisms available to inspectors, as detailed in Section 9.4.5 of the DAMP, are as follows (in increasing order of severity):
Notice of Non-compliance
Administrative compliance orders
Cease and desist orders
Infractions and misdemeanors
While these measures typically escalate in enforcement action, they are not required to be issued in the exact order presented here. City inspectors will apply or recommend any of the enforcement steps as appropriate based on the enforcement consistency guide (Included as an Exhibit 4.I of DAMP Section 4). The City of Yorba Linda will ensure that violations of a similar nature are subjected to similar types of enforcement remedies.
A-9.1.7 Training and Outreach
A-9.1.7.1 Training
A total of six training modules covering different aspects of the Model Existing Development
SECTION A-9, EXISTING DEVELOPMENT
City of Yorba Linda July 1, 2003
Local Implementation Plan (LIP) 8
Program have been developed. These modules are provided in DAMP Appendix B, Section B9. The modules that address implementation of the industrial component of the program include the following:
Existing Development Program Management Module (Appendix B, Exhibit B-9.I) This training module is targeted to Storm Water Program Managers. The module includes an overview of the Existing Development Program and then detailed discussions of the requirements that storm water managers must address in their local implementation plans.
Step by step instructions are provided to aid the managers in preparing their LIPs for industry, commercial businesses, residential, and common interest areas.
Field Implementation of Existing Development Program Module (Appendix B, Exhibit B-9.II) This training module is targeted to staff responsible for code enforcement and inspection of industrial and commercial facilities. The module addresses the basic program element requirements and then provides detailed instruction on conducting inspections, including inspection forms, record keeping requirements, and enforcement tools available for code violations.
A-9.1.7.2. Outreach
The outreach strategy for reaching industrial businesses includes efforts such as providing links to storm water information on the County’s webpage, conducting mass mailings, and development & distribution of brochures, posters, fact sheets, etc. The outreach component of the DAMP (Section 6) goes into specific detail on requirements for the approach of outreach efforts and the materials that have currently been developed are included in DAMP Appendix B, Section B-6.
A-9.1.8 Program Effectiveness Assessment
The overall Program Effectiveness Assessment (PEA) serves as the foundation for the submittal of the annual progress report that is submitted each year to the Principal Permittee and subsequently to the Regional Boards and serves as the basis for evaluating each municipality’s individual industrial program efforts (See DAMP Appendix C, Section C-8).
The PEA allows each municipality to assess the effectiveness of their individual storm water program components including those focused on addressing storm water and non-storm water discharges associated with industrial activity. The industrial program effectiveness assessment will enable the City to evaluate the effectiveness of the local program by focusing on data collected from the inventorying, prioritization, BMP implementation, inspection and enforcement of industrial facilities as well as training records.
