Development (LID)
performance
criteria. (Additional
Details in Section

7.II-2.4.3 of the
Model WQMP)
Priority Projects must infiltrate, harvest and use, evapotranspire, or biotreat, the 85th percentile, 24-hour storm event [Design Capture Volume (DCV)]. Infiltration, harvest and use, and/or
evapotranspiration must be utilized to the extent feasible before considering biotreatment.

LID requirements may be met within the project footprint as described in Section IV.3.2 below and/or at a sub-watershed scale (Section IV.3.3 below).

List applicable
treatment control
BMP performance
criteria. (Additional
Details in Section

7.II-3.2.2 from
Model WQMP)
LID performance criteria have been met through retention of the DCV within the project footprint and/or at a sub-watershed scale.

Treatment control requirements are fully met.

LID performance criteria have been met through biotreatment of the remaining DCV not feasibly retained; biotreatment BMPs have been selected to have a medium to high effectiveness for treating the primary POCs.

LID performance criteria are not fully met by retention or biotreatment; treatment control requirements are met by selecting treatment control BMP to have a medium to high effectiveness for treating the primary POCs and sizing treatment control BMPs for the remaining portion of the DCV.

It is not feasible to provide LID or treatment control BMPs for the entire DCV. An alternative compliance plan is prepared utilizing credits from the BMP Exchange.

Calculate LID DCV
for Project.
(See Master WQMP
Section 3.7)
DCV = C x d x A
DCV in cubic feet
C = runoff coefficient
d = design capture depth (in)
A = total tributary area (sq ft)

This Project WQMP template provides the structure and outline required for all WQMPs prepared for Disneyland Resort projects. This section contains additional information, instructions, guidance, and entry examples, to aid the preparer in completing the Project WQMP. This document is only to be used as a guide.

Using or editing older versions of a WQMP may lead to approval delays by the City of Anaheim. Other templates from other cities or sources are not acceptable for Disneyland Resort projects.

The Project WQMP template itself does not include instructions or guidance to facilitate completion of the document. Only limited instruction is provided within this user’s guide.

The Project WQMP template references related and important technical guidance that stipulates regulatory requirements which should be consulted as needed. All technical documents, forms and templates used to prepare a project or sub-watershed BMP WQMP document are found on The Hub. Technical guidance includes:

1. The 2014 Resort Master WQMP (OTH2014-00732) approved by the City of Anaheim

2. The Orange County Technical Guidance Document (TGD) and Appendices (DAMP Exhibit 7.III)

3. The County of Orange Model WQMP (DAMP, Exhibit 7.II, May 19, 2011)

4. The Orange County Municipal Storm Water Permit NPDES Permit No. CAS618030 Using the Template
This Project WQMP template is structured as a “fillable form” with fields formatted for easy entry of data and information. The ability to change the formatting in the WQMP template is restricted and information and data may only be entered in the form fields.

Some fields will automatically populate themselves from information provided in the first fillable area for that specific entry (e.g. Project Name). NOTE: these fields may not show as populated until the “print” or “print preview” function for the document has been used.

Depending on the version of Word being used, go to “Print” or “Print Preview,” and then “Close Print Preview” or return “Home”. Automatically or self-populated fields should now be updated and visible.

Fields in this template are generally of three types as shown below:

Text entry fields appear as gray areas and are provided where specific entries are required or for text that has an “or” option and requires a selection between two choices. Default text appears in most of these fields to indicate what type of information is being requested in the field.

Project Water Quality Management Plan (WQMP) Template
DISNEYLAND RESORT User’s Guide
December 2014 Page 3
Self-populating fields will appear as normal text. These fields take information entered in corresponding “text entry fields” and populate an area where repeat information is requested.

Examples include the project name and engineer information, which are first requested on the cover page and will automatically populate the document’s header and Engineer’s Certification page, respectively. See the note on the previous page for help with viewing these fields after they are updated.

Check boxes to indicate a choice, such as Yes No, are provided and can be checked or unchecked by clicking on the box.

NOTE: The template’s Table of Contents (TOC) is also a self-populating field. An error in the Microsoft Word program may cause the TOC to reflect that all sections in the document are on the same page. In order for this field to reflect accurate page numbers, scroll to the final page in the template, put the cursor in the text entry field on the last page, then depending on the version of Word in use, go to “Print” or “Print Preview,” and then “Close Print Preview” or return “Home.” Users of Word 2013 may need to select “print current page only” and print the final page in order for the TOC to refresh. Saving the document may also force an accurate reflection of the page numbers for users of Word 2013.

It is recommended that prepare seek assistance or support from a word processing expert if difficulty is encountered with this form.

Using this User’s Guide
This User’s Guide goes section-by-section through the Project WQMP template and provides instructions and sample text to assist the preparer in its completion.

EXAMPLE TEXT
The site generally flows from the northwest to the southeast through a combination of downspouts, curb and gutter, vegetated BMPs, storm drain inlets, and storm drain pipes. Runoff from the entire project concentrates at a connection to the existing storm drain in the SE corner of the site (See Section VI - BMP Exhibit and Site Plan).

Narrative Project
Description:
(Use as much space as
necessary.)

EXAMPLE TEXT
The project is a design build phased project which includes expansion of DCA BOH on already developed, mostly paved areas, so there will be very minimal increase of impervious foot prints. Project is divided into several small scope items, each scope would be developed at different time based on schedule. Subject WQMP includes 4 scope items only and considers all 4 scope items as a single project.

Following is the list of scope items:
 Custodial DCA Multipurpose Building
 Central Maintenance Facility East
 DCA Entertainment Complex
 DCA Production Kitchen – Flex Office
The total area of the project is 2.0 acres or 87,120 square feet, of which includes the buildings/structure, parking areas and landscaped area.

There are no retail stores and sit down eating places associated with the proposed redevelopment.

Custodial DCA Multipurpose Building
The Custodial DCA Multipurpose Building is a 2-story building to the existing Monsters Inc attraction building, north of the Monorail, in the northeast area of the DCA BOH. This office is a multi-functional space, intended to be the home base operational area for the Custodial Operations at Disney's California Adventure & Down town Disney. It will also be the central check in area for over 500 Custodial Hourly Cast Members and will be used 24/7.

Exterior Access and Parking Area includes (7) Electric cart parking spaces with (120v AC 20 amp) charging outlets……..

EXAMPLE TEXT
Roof runoff from building 2 and 4 is collected in the roof downspouts and discharged into a biofiltration planter box located on the east side of the building. Runoff from storage area for building-2 also drains into the planter box. Half of the roof of building 6 also drains in to the planter box. Out of 1.8-ac of disturbed area about 0.78ac is treated by the proposed planter box.

Location of the planter box is shown on the BMP Plan and Site Plan for Building 2, 4 & 6 in Attachment C.

The parking/drive area of building 2, 4 and 6 which is about 0.9 acres, follows the existing drainage pattern and continues to drain to the existing catch basins located in the existing Timon Parking Lot. Porous asphalt pavement surface is provided in most of the parking stalls for building 2, 4 and 6.

Drainage leaves the project footprint in via a connection to an existing storm drain.

Water then flows through the Resort storm drain system to Outfall 2 to the City of Anaheim MS4.

Standard text provided at the bottom of the entry box
(LEAVE AS-IS. DO NOT ALTER OR DELETE):

The immediate downstream receiving water from the City of Anaheim’s MS4 is the Anaheim Barber City Channel, which connects to the Bolsa Chica Channel and drains to Sunset-Huntington Harbour through Anaheim Bay to the Pacific Ocean.

Non-Priority Project Water Quality Plan (NPPP)
The Orange County Stormwater Program has developed this Non-Priority Project Water Quality Plan (NPPP) for new development / significant redevelopment projects that do not meet the criteria for Priority Projects as defined within the County’s Model Water Quality Management Plan (see Model WQMP Sections 1.3 and 1.4) but that qualify as Non-Priority Projects as defined in the Drainage Area Management Plan (DAMP). These projects are required under the Santa Ana Regional Board MS4 Permit (North Orange County Permit) to “document, via a WQMP or similar mechanism, site design, source control and any other BMPs which may or may not include treatment control BMPs”. This plan covers both private and public agency projects that qualify as Non-Priority Projects.

Qualifying Non-Priority Projects are projects that do not fall under one of the Priority Project Categories defined within the Model WQMP but meet one of the following conditions:
 Require discretionary action that will include a precise plan of development, except for those projects exempted by the Water Quality Ordinance (as applicable); or  Require issuance of a non-residential plumbing permit for hazardous pipelines as defined in the County or local Water Quality / Stormwater Ordinance. Non-residential plumbing projects that do not pose a potential threat to public safety do not require a WQMP for approval.

A “discretionary action” under CEQA is defined as “an activity which requires the public agency to exercise judgment in deciding whether to approve or disapprove the particular activity, as distinguished from situations where the public agency merely has to determine whether there has been conformity with applicable ordinances or other laws.” (California Public Resources Code § 21080(a); CEQA Guidelines § 15357). Examples of discretionary actions include: feature plans, area plans, use permits, site development permits and special use permits. “Ministerial actions” under CEQA are those where little or no judgment or deliberation by a Permittee is required or possible. Generally, the only example of a ministerial approval action that would qualify as a Non-Priority Project would be a project that requires the issuance of a Non-Residential Plumbing Permit.

All other projects and activities that only require a ministerial grading or building permit for which the Permittee has no discretion to approve do not fall under the requirements of this new development program, with the exception of projects that require a Non-Residential Plumbing Permit.

This plan is provided for summarizing basic project information and stormwater Best Management Practices that are planned for controlling discharges of pollutants from proposed Non-Priority Projects and identify applicable source conrol BMPs, site design features, and determine BMP maintenance requirements. Non-Priority Project proponents are required to complete the plan for local jurisdiction review and approval. Applicable sections of the Technical Guidance Document are referenced for assistance with completing each NPPP section. All Non-Priority Project Water Quality Plans must be in compliance with the Local Implementation Plan developed by each local agency. The local jurisdiction may request additional information necessary for local Non-Priority Project review and approval.

Local jurisdictions may modify existing templates for local program implementation to incorporate the information contained in this Plan provided all information necessary to meet requirements contained in the MS4 Permit and the DAMP for Non-Priority Projects are contained within the local plan.

NPDES Storm Water Pollution Prevention Plan (SWPPP)
DLR NPDES SWPPP Revision 09 PAGE 1

1. Introduction
This Storm Water Pollution Prevention Plan (SWPPP) has been developed for Disneyland Resort (Resort) located in the City of Anaheim (City), California. The Disneyland Resort includes: two theme parks ‐ Disneyland and Disney California Adventure (DCA); three hotels ‐ Disneyland Hotel, Disney’s Paradise Pier Hotel, and Disney’s Grand Californian Hotel & Spa; and Downtown Disney, which is a retail, dining, and entertainment district. The purpose of this SWPPP is to assist Disneyland Resort in meeting specific state and federal regulatory requirements by reducing storm water pollution to the maximum extent practicable (MEP). The SWPPP is also intended to be a tool to educate Disneyland Resort staff (Cast Members) about storm water pollution, how and where it occurs at the Resort, and about methods and practices known as Best Management Practices (BMPs) to prevent or reduce pollution at the source, before it enters the storm water drainage system.

Disneyland Resort has been a leader in environmental awareness and protection for many years. This SWPPP is intended to complement and enhance other existing environmental pollution prevention regulatory programs such as the Spill Prevention, Control, and Countermeasure (SPCC) Plan and the Hazardous Material Release Response (HMRR) Plan.

The SWPPP is a document that shall be retained on site. It is available to the public under Section 308(b) of the Federal Clean Water Act (Clean Water Act) and is to be made available upon request to representatives of the California State Water Resources Control Board (SWRCB) and Regional Water Quality Control Board (RWQCB).

This introductory section is intended to provide the regulatory background that sets forth the need for a SWPPP. This section also includes a discussion of the objectives upon which the SWPPP is based.

1.1 Regulatory Background
Both the state and federal governments have determined that storm water runoff is a significant source of water pollution in creeks, rivers and other water bodies in California. The United States Environmental Protection Agency (EPA) and the SWRCB regulate storm water runoff from municipalities, construction sites, and industrial facilities as a first step towards reducing this source of pollution. The regulations may require facilities such as the Resort to obtain a permit to discharge storm water runoff. The permit sets conditions for acceptable discharges of storm water runoff from the permittee's facility. Although support properties (e.g., parking lots) are not required to obtain a storm water discharge permit, the SWPPP designates these locations with BMPs designed to ensure that storm water pollution is reduced to the MEP.

The Clean Water Act prohibits certain discharges of storm water containing pollutants except in compliance with a National Pollutant Discharge Elimination System (NPDES) permit [33 U.S.C. §§ 1311, 1342 (also referred to as Clean Water Act §§ 301, 402)]. The EPA promulgates federal regulations to implement the Clean Water Act’s mandate to control pollutants in storm water discharges (40 C.F.R. § 122, et seq.). The NPDES permit must require implementation of Best Available Technology Economically Achievable and Best Conventional Pollutant Control Technology, collectively known as Best Management Practices or BMPs, to reduce or prevent pollutants in storm water discharges and authorized non‐storm water discharges to the MEP. The NPDES permit must also include additional requirements necessary to implement applicable water quality objectives or water quality standards (water quality standards, collectively).

On November 16, 1990, the EPA promulgated Phase I of the storm water regulations in compliance with section 402(p) of the Clean Water Act (55 Fed. Reg. 47990, codified at 40 C.F.R. § 122.26). These ENVIRONMENTAL POLICY/PROCEDURE (Water) Doc #: SWPPP – R09 The Disneyland®
Resort
NPDES Storm Water Pollution Prevention Plan (SWPPP)
DLR NPDES SWPPP Revision 09 PAGE 2
regulations require operators of facilities subject to storm water permitting, i.e. those that discharge storm water associated with industrial activity (industrial storm water discharges), to obtain an NPDES permit. Section 402(p)(3)(A) of the Clean Water Act also requires that permits for discharges associated with industrial activity include requirements necessary to meet water quality standards. The SWRCB has been delegated authority by the EPA to administer the NPDES permit program in California. The discharge of storm water runoff from the Resort is currently regulated by NPDES Permit No. CA0106283 (Permit) adopted by the Santa Ana RWQCB as Board Order No. R8‐2008‐0001, on January 18, 2008, which replaced Order No. R8‐2003‐0001 (issued January 17, 2003). The Permit was issued pursuant to section 402 of the Clean Water Act. This SWPPP has been prepared to comply with the conditions of Attachment I of the Resort’s NPDES Permit (Order No. R8‐2008‐0001).

1.2 Objectives
The objectives of this SWPPP are: (1) to identify and evaluate sources of pollutants associated with industrial activities that may affect the quality of storm water discharges and authorized non‐storm water discharges from the facility; and (2) to identify and implement site‐specific BMPs to reduce or prevent pollutants associated with industrial activities in storm water discharges and authorized non‐storm water discharges to the MEP.

This SWPPP is intended to outline methods to reduce the impact of industrial activities on storm water runoff. Disneyland Resort is a unique industrial facility. Many practices that protect storm water runoff quality have been in place at the Resort since long before the storm water regulations were published. A large number of maintenance activities, good housekeeping practices, and employee‐training programs existed prior to the introduction of the regulations and the Resort’s Permit because they are consistent with the Resort's standard business practices and environmental stewardship goals.

Minimizing storm water pollution is accomplished by educating Cast Members and maintaining good housekeeping practices and storm water management facilities at the site.

1.3 Planning and Organization

1.3.1 Other Requirements and Existing Facility Plans
This document is intended to build upon existing, effective practices and programs rather than invent a separate program. Documents such as the Resort’s SPCC and HMRR Plans have therefore been used as references for this SWPPP. These plans, as well as the preventive maintenance procedures and extensive interviews with key facility employees, served as the basis for much of the storm water pollution control practices and BMPs included in this SWPPP.

As stated in Attachment I of the Permit, “The SWPPP requirements are designed to be sufficiently flexible to meet the various needs of the facility. SWPPP requirements that are not applicable to the facility should not be included in the SWPPP.” This SWPPP is therefore organized to assure it not only meets the requirements of the Permit, but that it also serves as a useful tool to implement BMPs.

In addition to summarizing the BMPs implemented generally throughout the Disneyland Resort, this SWPPP also includes a separate section dedicated to each of the four major departments identified as potential pollutant sources. This separation allows for specific management and training of Cast Members within each department regarding the sources of pollutants and the site‐specific BMPs applicable to their duties. Management from each of these departments worked in partnership with the Environmental Affairs Department to develop and update each section.

2. Site Description and Potential Pollutant Sources
Disneyland Resort is located at 1313 Harbor Boulevard, Anaheim, California. The Resort covers an area of approximately 170 acres. The "On Stage" portion of Disneyland Resort is comprised of theme park attractions, rides, restaurants, shops, and three hotels. The “Back of House” portion of the Resort includes operation and maintenance support facilities, warehousing and storage, waste management, and material and equipment delivery.

2.1 Site Map
Figure 2‐1 provides an overview map of Disneyland’s On Stage and Back of House areas, the storm drain system, flow direction, and major structures (e.g., catch basin inlets, manholes). Similarly, Figure 2‐2 provides an overview of Disney California Adventure and its corresponding On Stage and Back of House areas and storm drain system features.

Storm water runoff from the Resort’s On Stage area flows to nine different discharge locations. These discharge locations are designated as M‐001, M‐002, M‐003, M‐005, M‐5D, M‐5E, M‐6C, M‐22B, and M‐ 34A. Storm water from the west, south, and north central portions of Disneyland flows to M‐001. Flow from the northern area discharges at M‐002, and flow from the eastern side of Disneyland discharges at M‐003. Storm water from the Disneyland Hotel discharges at M‐005. Drainage from Finding Nemo Submarine Voyage – during rehab only – flows to M‐03A. Storm water from a portion of Paradise Pier Lagoon at DCA flows to M‐5D, M‐5E, and M‐6C. Flow from the northern portion of DCA also discharges at M‐6C. Storm water from the northern and north‐central areas of DCA, Downtown Disney, and Disney’s Grand Californian Hotel & Spa discharges at M‐22B. Flow from the majority of DCA, including the northeast and southeast potions, discharges at M‐34A. Runoff from the north central and west central areas of Disneyland flows into the recirculating water system which flows to M‐001.

2.2 General Identification of Activities and Areas which are Potential Pollutant Sources
Disneyland Resort owns and operates two theme parks consisting of a number of attractions, including mechanical rides, amusement devices, live entertainment, refreshment stands, and other food services.

Ornamental water systems are an integral part of a number of the attractions. The Disneyland Resort owns and operates three hotels – Disneyland Hotel, Paradise Pier Hotel, and Disney's Grand Californian Hotel & Spa – and manages Downtown Disney, which is a retail, dining, and entertainment district.

The Resort is classified under SIC 7996 Amusement Parks, which covers theme parks, kiddie parks, amusement piers, centers, and parks, and other establishments (excluding fairs, circuses, and carnivals) that operate in part or whole such attractions as mechanical rides, amusement devices, refreshment stands, and picnic grounds.

Although activities at the Resort do not fall under manufacturing or treatment, as is the case with industrial facilities, numerous chemical products are used to maintain attractions and the facility on a routine basis.

2.3 Assessment of Potential Pollutant Sources
The Resort has developed a process to identify activities and areas that have the potential to generate or may be sources of pollutants that may enter the storm drain system. The following sections provide an overview of the assessment of potential pollutant sources, departments/areas, and activities. This document is organized to facilitate implementation of BMPs by pollutant, pollutant sources/activities and departments. Detailed procedures and BMPs for each potential source by department are included in the tables in Sections 4 through 7 – Potential Pollutant Sources and Best Management Practices. The tables include the specific BMPs that apply to each of six important BMP groups: materials handling and storage, housekeeping and other best management practices, spill prevention and response, employee training, waste recycling/disposal procedures, and record keeping, internal reporting, inspection and quality control.

2.4 List of Significant Materials
The Disneyland Resort submitted a list of all chemicals along with their Material Safety Data Sheets (MSDS) to the RWQCB on August 25, 2003. The list of potential pollutant categories or operations has been identified from the list of specific products and chemicals used at the Resort and are (in alphabetical order) as follows:
 Acids (dilute and batteries)
 Ammonia
 Bleach
 Cleaning solvents (degreasers)
 Detergents
 Dirt/debris
 Fertilizers
 Food particles, wastes, materials
 Fuels
 Glues, adhesives, resins, fillers
 Gun powder
 Hazardous materials
 Inks
 Lubricants
 Manure
 Metals
 Non‐hazardous waste
 Oil (petroleum, cooking, etc.)
 Paper, paper ash
 Paints (water‐based, oil‐based, glazes)
 Paving operations
 Plaster, cement, putty
 Polishes
 Propane
 Regulated wastes
 Sawdust
ENVIRONMENTAL POLICY/PROCEDURE (Water) Doc #: SWPPP – R09 The Disneyland®

 Sediments, soil
 Solvents (Thinner, fixers, developers)
 Structure construction (painting and
roof work)
 Urethane and polyvinyl (products and
materials)
 Vehicle and equipment fueling
 Vehicle and equipment cleaning
 Waste lubricants
These pollutant categories or activities are included as part of the tables in Sections 4 through 7 and support the selection and implementation of BMPs.

2.5 General Description of Potential Sources

2.5.1 Operations
Disneyland Resort’s Environmental Affairs Department (Environmental Affairs) performed a thorough review of each of the operational activities and areas (in lieu of industrial processes as they are more indicative of Resort’s function) that could be potential pollutant sources to storm water as a part of the preparation and subsequent revisions of this SWPPP. The following departments at Disneyland Resort were identified as managing activities or areas of potential pollutant sources:
 Facilities and Operations Services
 Park Operations
 Entertainment
 Food and Beverage
As noted above, this SWPPP includes a separate section dedicated to each of these four major departments identified as a part of the review. This allows for specific management and training of Cast Members within each department regarding the sources of pollutants and the site‐specific BMPs.

Management from each of these departments worked in partnership with Environmental Affairs to develop each section.

Refer to Sections 4 through 7 for specific potential sources and activities.

2.5.2 Material Handling and Storage Areas
The Resort operates a central receiving area for all material handling and deliveries. Centralized receiving allows for better management of all materials and personnel handling the materials. Materials are stored in buildings or under cover and on impervious surfaces where practical prior to distribution to minimize exposure to storm water. Larger deliveries are transported to their final locations for storage when staging at the receiving facility is limited. Detailed procedures for handling and storage are included in Sections 4 through 7 – Potential Pollutant Sources and Best Management Practices as they apply for each of the departments.

2.5.3 Dust and Particulate Generating Activities
Dust and particulate generating activities are minimal, dispersed and typically associated with other types of activities or operations at the Resort. As such these activities are generally considered with the primary operation when it comes to addressing the pollutants they may generate and the BMPs selected may specifically target all pollutants from the activity to maximize effectiveness.

In general, the unpaved portion of the Disneyland Resort is landscaped with grass, flowers, trees and shrubs. Because these unpaved areas are landscaped with vegetation, soil erosion is negligible and ENVIRONMENTAL POLICY/PROCEDURE (Water) Doc #: SWPPP – R09 The Disneyland®
Resort
NPDES Storm Water Pollution Prevention Plan (SWPPP)
DLR NPDES SWPPP Revision 09 PAGE 9
sediment does not have a potential to pollute storm water. However, fertilizers and pesticides are used on this vegetation and these chemicals do pose a risk of polluting storm water.

The paved areas are used primarily as walkways for the thousands of people that visit Disneyland Resort every day. Debris left by guests, such as food particles, soft drink liquids, shoe leather, and rubber, along with dust and debris (e.g., green litter, trash, and dirt and debris) accumulate on the paved walkway surface and have the potential to be released in storm water runoff.

2.5.4 Significant Spills and Leaks
Significant spills and leaks may only originate at very specific locations throughout the Resort and potentially originate from storage of larger quantities of materials or wastes. As noted earlier, the Resort’s central receiving area is one location for materials that could lead to spills and leaks. Another possible source is the Environmental Activity Center (EAC) where solid, liquid and hazardous wastes are managed and stored until they are transferred for final disposal. Centralized receiving allows for better management of all materials and personnel handling the materials. Spills may also take place from the sanitary sewer system. Spill response and management is conducted in accordance with the Resort’s SPPC Plan with BMPs specified to minimize storm water system discharges.

The Maintenance Response Team is contacted for larger spills. Detailed procedures for spill prevention and response are included in Sections 4 through 7 – Potential Pollutant Sources and Best Management Practices.

2.5.5 Non‐Storm Water Discharges
Disneyland Resort’s Permit states, “The discharger shall investigate the facility to identify all non‐storm water discharges and their sources.” Non‐storm water discharges may occur at the Resort from a variety of sources and locations as identified in Sections 4 through 7. Non‐storm water discharges, if they occur, are unlikely to include hazardous materials or wastes as those are specifically stored and handled in accordance with the Resort’s HHMR and SPPC Plans with BMPs specified that have a positive impact on storm water and non‐storm water discharges.

The elimination of non‐storm water discharges is a major element of the SWPPP. Non‐storm water discharges can include illicit connections (e.g., floor drains connected to storm drains), improper dumping, spills, and leakage from storage tanks or transfer areas. Improved management practices can often eliminate dumping, spills, and leakage and are in place throughout the Resort.

2.5.6 Soil Erosion
Landscape and hardscape improvements throughout the Disneyland Resort are used to reduce soil erosion and eliminate the potential for soil, sediment, or debris from entering the storm drain system.

Areas are developed to include trees, plants, and ground cover, incorporating the use of geotextile fabrics and mulch, controlled automated drip irrigation and containment curbs and berms which all work together to prevent the erosion of soil in On Stage and Back of House areas. Construction activities are a potential source of soil erosion and sediment discharge.

3. General Resort Storm Water Best Management Practices Disneyland Resort implements many practices to protect storm water quality. This section documents these practices for new and existing employees as well as regulators who may review this SWPPP.

The Permit requires that the Disneyland Resort consider a variety of BMPs including non‐structural, good housekeeping, preventive maintenance, and spill response to address the identified potential sources listed in Section 2. The Resort’s unique activities, management structure by departments, and sources make it more plausible to organize the BMPs as noted earlier and presented in Sections 4 through 7.

In general, BMPs are used to minimize pollutant exposure to rain water and storm water contamination.

BMPs may include a wide range of non‐structural practices from Cast Member training to facility inspections. Structural BMPs may include permanent berms, storm water pollution interceptors, automatic storm water diversion valves, spill kits and absorbents, or additional treatment of roof runoff at the source (such as filters on roof downspouts). Good housekeeping BMPs includes surface cleaning and maintenance, extensive sweeping (both manual and mechanical), trash and debris removal (both manual and mechanical), etc. Methods of pollution control, or BMPs, currently being used at the Resort are described in the following sections for each of the operations departments previously identified and BMPs are included as noted early in six main groups (see Section 2.3). Specifically, Sections 4 through 7 list the sources of pollutants and the site‐specific BMPs by department. Management from each of these departments worked in partnership with Environmental Affairs to develop each section. The sections provide a discussion of the pollution control measures common to all areas and also target the specific management and training needs of Cast Members within each department.

3.1 General Resort‐wide BMPs
Numerous BMPs currently implemented throughout the Disneyland Resort are not specific to a given operation. These BMPs may have multiple benefits in reducing pollutants and pollutant sources. They have been adopted throughout the Resort and include the following:

3.1.1 Non‐Structural BMPs
Non‐Structural BMPs may include good housekeeping, materials and waste handling and storage practices, spill response, and other similar BMPs.
 The Custodial Guest Services Department sweeps all asphalt in Back of House area weekly or more frequently as needed and prior to the start of the rainy season with a regenerative air sweeper. Trash is picked up along the exterior fence line around the property as needed.  Annually, the Disneyland Resort Infrastructure Department cleans all storm drain lines and catch basins prior to the first rain event of the season.
 Materials are distributed and stored in small quantities to minimize the risk of spills.  The Cast Members at the EAC implement a Resort‐wide waste management system. Limiting the number of Cast Members handling hazardous materials minimizes the potential for spills.  All wastes are segregated by the shops into designated hazardous waste containers, recyclables and disposal containers. These wastes are picked up by the EAC.

 Materials inventory is closely controlled pursuant to Air Resources Control Board standards and material issuing areas are all indoors. This control reduces the potential for spills.  All Back of House operations require Resort Cast Members to be responsible for the housekeeping of their own work areas. These areas are cleaned at the end of each day.  Biodegradable cleansers and solvents are used for cleaning activities whenever possible.  The majority of coatings used in painting operations are water base. All are lead‐free paint.  Most materials are stored indoors, minimizing the potential for contact with storm water.  Absorbent material is available throughout the Back of House area and is stored in close proximity to operations with potential to threaten storm water.  The Back of House area is enclosed by a security fence and patrolled by security personnel 24 hours a day to control unauthorized activity that could lead to environmental contamination.

3.1.2 Structural BMPs
 Overhead Coverage – Products are delivered through a centralized receiving department for distribution throughout the Disneyland Resort. Materials are stored under cover where practical.

Each line of business has designated storage facilities for new and used product storage. Storage lockers, covered outdoor storage, the use of spill containment pallets, temporary covers (canopies and polyethylene sheeting pallet covers), and offsite warehousing are utilized as needed.
 Retention Ponds – StormChamber® devices in select areas treat and infiltrate runoff from impervious areas, including roofs and Back of House roadways. This technology is a subterranean, open bottom, high‐density polyethylene infiltration chamber, which functions in both permeable and non‐permeable soils and takes advantage of the natural infiltration and treatment process of the underlying soil.

Storm water runoff from impervious surface is treated by infiltration basins onsite. As water migrates through porous soil and rock, pollutant attenuation mechanisms, including precipitation, sorption, physical filtration, and bacterial degradation are at work. This design has high removal efficiencies for particulate pollutants and moderate removal of soluble pollutants.  Control Devices – Berms, curbs, and diversionary devices have been designed and constructed in such a way to prevent potential run‐on and runoff of storm water in areas that could cause an increase in pollutant loading in storm water. Other control devices include oil/water separators, automatic diversion valves that redirect the first flush of areas such as wash pads, trash compactors, and sorting and recycling locations, and the use of pretreatment inline filters to remove solids, metals, and oil and grease from storm water runoff.  Secondary Containment Structures – Spill containment structures or devices have been installed under product containers, equipment and machinery, and storage lockers and equipment rooms per the requirements of the SWPPP and SPCC Plan. These structures or devices are routinely inspected and maintained as needed.

Resort
NPDES Storm Water Pollution Prevention Plan (SWPPP)
DLR NPDES SWPPP Revision 09 PAGE 12
 Treatment – Several BMP technologies have been incorporated into remodels of existing infrastructure and redevelopment projects throughout the Disneyland Resort to treat roofed, paved and landscaped areas. For many roofed areas, FloGard® downspout filters have been installed to pre‐treat runoff. The downspout filters are designed to treat oil, grease and sediment in the roof runoff before it enters an infiltration unit that allows for water capture and groundwater recharge. In many areas, the pre‐treated roof runoff is discharged to secondary treatment/infiltration devices to recharge the groundwater table. Infiltration pits are located under walkways undetectable to guests visiting the Disneyland Resort.

Stormceptor® systems are also utilized as an effective, tested and proven storm water management solution for new and existing facilities. The treatment system slows incoming storm water to create a non‐turbulent treatment environment, allowing debris to rise and sediment to settle. Also, the system can maintain continuous positive treatment of total suspended solids, regardless of the flow rate, treating a wide range of particle sizes as well as free oils, heavy metals and nutrients attached to fine sediments.

Other storm water treatment BMPs implemented since 2012 include vegetated swales (biotreatment units), downspout filters for treating roof runoff, vortex separators, eight acres of porous pavement, 15 infiltration basins, several trenches and dry wells, and numerous storm drain filtration inserts. The BMPs are being effectively managed and maintained by the Disneyland Resort Environmental Affairs team, which ensures that all BMPs are serviced on a regular basis. The regular maintenance ensures that all devices are performing at their highest efficiency.

3.2 Inspection Program and Preventive Maintenance
A comprehensive inspection and preventive maintenance program is implemented for non‐structural and structural BMPs at the Resort. Routine inspections are planned, scheduled and completed to minimize the non‐storm water discharges, identify Cast Member training needs, document potential for spills or leaks due to equipment failures and routine operations, and track any failing or deficient BMPs. Disneyland Resort has an extensive ongoing preventive maintenance program at the facility. The program includes a history of inspection records and blank inspection forms to be completed by Cast Members during inspections.

Routine inspection of the Resort’s potential sites for non‐storm water discharges take place as part of environmental auditing practices and are scheduled quarterly as department self‐audits. These inspections are designed to identify any potential or existing non‐storm water discharges and initiate corrective actions.

A thorough investigation of the storm drain system serving Disneyland Resort Back of House areas is performed annually for the purpose of identifying any illicit connections which would be documented using the table template included in Appendix A. Environmental Affairs performs annual audits of the facility to verify compliance with environmental regulations (including storm water).

3.3 Spill Response
Cast Members receive hazardous material communication and hazardous waste handling training.

Environmental Affairs coordinates with all departments annually to inform appropriate Cast Members at all levels of their responsibilities as outlined in the SWPPP as well as general storm water requirements that prohibit the discharge of any wastes to the storm drain system. Spill kits are located throughout the Disneyland Resort where the potential exists for accidents and Cast Members are trained to clean up spills immediately and dispose of materials properly. Storm drain inlets are protected from spills and clearly ENVIRONMENTAL POLICY/PROCEDURE (Water) Doc #: SWPPP – R09 The Disneyland®
Resort

DLR NPDES SWPPP Revision 09 PAGE 13
marked, as needed. The Maintenance Response Team is contacted for larger spills. Detailed procedures for spill prevention and response to non‐storm water discharges that may occur at the Resort from a variety of sources and locations are identified in Sections 4 through 7. Non‐storm water discharges, if they occur, are unlikely to include hazardous materials or wastes as those are specifically stored and handled in accordance with the Resort’s HHMR and SPPC Plans with BMPs specified that have a positive impact on storm water and non‐storm water discharges. Significant spills and leaks are documented using the table template included in Appendix B.

3.4 Material Handling and Storage Areas
The Resort operates a central receiving area for all materials handling and deliveries. Materials are stored in buildings or under cover and on impervious surfaces where practical prior to distribution. Larger deliveries are transported to their final locations for storage when staging at the receiving facility is limited. Materials are purchased and/or transported in the minimal quantities possible to minimize the potential for spills. Spills are cleaned up immediately and disposed of properly. Detailed procedures for handling and storage are included in Sections 4 through 7 – Potential Pollutant Sources and Best Management Practices as they apply for each of the departments.

3.5 Cast Member Training
Disney Development Connection (a department within Disneyland Resort) and Environmental Affairs are responsible for implementing various training courses. Cast Member training guidelines are extensive. A section of training focuses on spill prevention and therefore relates closely to storm water pollution prevention.

Roll Call meetings are held daily to discuss safety and operational issues, procedural updates and guest satisfaction guidelines. Throughout the month, a portion of the agenda is devoted to storm water pollution prevention and BMPs. This informal setting is used to communicate immediate needs to support the program, provide feedback to sustain the overall success of the program through team support, and provide updates to practices that help improve the Disneyland Resort’s overall execution of the program. SWPPP‐related communications are also provided to Cast Members through Team Talks (written communication), monthly environmental newsletters, brochures, and online computer based training.

Additional training is conducted with changes in facility procedures, or with the introduction of an MSDS for a new material at the facility. Daily startup meetings address changes in procedures, issues that may arise, and operational improvements as needed.

Custodial Guest Services Department Cast Members are trained to distinguish between sanitary sewer and storm drains. They are instructed in the drainage patterns of the storm drain system and understand that all materials must be prevented from entering the storm drain system. A Back of House demarcation program installs and maintains signage at storm drain inlets and sanitary sewer locations. Communication of BMPs is also made available to Cast Members in English and Spanish with pictorials of signage that allows quick identification through color coding as well as embossed lettering.

The extensive training of Cast Members at the Disneyland Resort has been instituted to disseminate information about the impacts of pollutants on storm water and methods of preventing pollutants from entering the storm water system. The training program is presented to Cast Members and their supervisors who have duties and areas of responsibility that could impact storm water pollution (e.g., vehicle maintenance, materials handling, custodial, and general maintenance). The program includes the following:

ENVIRONMENTAL POLICY/PROCEDURE (Water) Doc #: SWPPP – R09 The Disneyland®
Resort
NPDES Storm Water Pollution Prevention Plan (SWPPP)
DLR NPDES SWPPP Revision 09 PAGE 14
 Background Information – Cast Members are briefed on the regulations derived from the Clean Water Act and the rationale for requiring industries and municipalities to develop and implement a plan to reduce storm water pollution. The term "storm water pollution" is defined and differences between sanitary and storm drain systems are explained.  Site Information – The facility site map is reviewed and the storm drain system, catch basins, sanitary sewer lines and drains, and drainage flow directions are indicated.  Pollution Prevention – Good housekeeping practices and materials management practices are described for various types of activities throughout the facility. Significant materials used on site that could cause pollution to storm water are identified as well as areas with the greatest potential for spills to occur.
 Pollution Control – Cleanup procedures and methods for containing spills are discussed and then demonstrated. Storm water pollution control measures throughout the facility are identified and maintenance procedures are introduced.
 Financial Liability – Cast Members are informed and alerted to the possible financial consequences which could be imposed upon Disneyland Resort for discharging significant pollutants to the storm drains.

3.6 Waste and Recycling Handling, Collection, and Disposal Activities Recycling, waste collection, and disposal activities are coordinated and managed at the EAC. Recyclable materials collection, solid waste management, hazardous waste storage, hazardous materials storage, solvent recovery, and trash compacting operations are centrally located at the EAC.

Materials delivered to the EAC from throughout the Disneyland Resort are sorted into designated dumpsters for recycling. These materials include garden waste, kitchen waste, construction waste, etc.

Hazardous materials, such as solvents and paints, are contained in designated drums to be picked up by a hazardous waste hauler. All of these materials are securely stored to prevent storm water contact and runoff. Only highly trained and qualified Cast Members operate the EAC.

3.7 Erosion Control and Site Stabilization
The Disneyland Resort is not generally subject to sediment erosion during routine operations. Sediment erosion during construction activities is managed through the implementation of construction BMPs and the implementation of a project specific SWPPP as specified by the State’s Construction General Permit (Order No. 2009‐0009‐DWQ; CAS000002), as applicable.

Landscape and hardscape improvements throughout the Disneyland Resort are used to reduce soil erosion and eliminate the potential for soil, sediment, or debris from entering the storm drain system.

The paved areas are used primarily as walkways, driveways, and parking were extensive sweeping and trash pick‐up is used to reduce pollutants.

ENVIRONMENTAL POLICY/PROCEDURE (Water) Doc #: SWPPP – R09 The Disneyland®
Resort
NPDES Storm Water Pollution Prevention Plan (SWPPP)
DLR NPDES SWPPP Revision 09 PAGE 15

3.8 Recordkeeping and Internal Reporting
The Resort maintains extensive recordkeeping for all the environmental programs it implements, including the storm water program. Databases and systems are used to track inspections, maintenance activities, spills, and action items for timely notification, reporting and effective data management.

Communications systems are also in place to support effective internal reporting and response. As appropriate, forms, and logs are maintained to support recordkeeping, internal and compliance reporting activities.

3.9 Quality Assurance
Quality assurance related to the implementation of this SWPPP and the described BMPs is in place and supported by the inspection and auditing system managed by the Environmental Affairs Department. Any deficiencies identified are corrected in a timely manner and adjustments to the SWPPP or BMPs are tracked for incorporation during the next planned revision. Disneyland Resort’s Environmental Affairs Department has dedicated fulltime Cast Members that perform daily process validation audits across the property in accordance with local, state and federal environmental requirements for programs that include hazardous waste, water quality, and air quality compliance.

Environmental auditing Cast Members perform site validation reviews Resort‐wide, develop and continuously improve the process validation program, report findings, track corrective actions, conduct trending analysis, and work closely with environmental program managers so they can effectively act as a liason to Environmental Affairs in the field as they interact with senior management and Cast Members on a daily basis.

3.10 Annual Comprehensive Site Compliance Evaluation
The tables in the following sections have been developed to document the specific BMPs implemented for each of the selected departments within Disneyland Resort as well as to serve as a useful tool for conducting the annual comprehensive site compliance evaluation. Each table is used by the respective individual department on a regular basis throughout the year to assure compliance with the Permit. In addition, an independent representative of the Environmental Affairs Department uses the tables to conduct an annual comprehensive site compliance evaluation at each department.

As a part of the annual evaluation, the Environmental Affairs Department reviews and evaluates each of the BMPs, both structural and non‐structural, to determine whether the BMPs are adequate, properly implemented, and maintained, or whether additional BMPs are needed.

In addition, the annual comprehensive site compliance evaluation, covering the reporting period of July 1 June 30, includes the following:

1. A review of all visual observation records, inspection records, and sampling and analysis results;

2. A visual inspection of all potential pollutant sources for evidence of, or the potential for, pollutants entering the storm drain system;

3. A review and evaluation of all BMPs (both structural and non‐structural) to determine whether the BMPs are adequate, properly implemented and maintained, or whether additional BMPs are needed; and

4. A visual inspection of equipment, such as spill response equipment, needed to implement the SWPPP.

The annual evaluation report includes:

8. Additional Programs and Best Management Practices
The Disneyland Resort implements numerous additional programs related to storm water pollution prevention and management that include innovative and proactive BMPs.

The following sections highlight the numerous programs in place at the Resort or in the vicinity of the Resort that positively impact storm water quality.

8.1 Post‐Construction Treatment BMPs
In 2008, the Disneyland Resort partnered with the City of Anaheim to develop a Master Water Quality Management Plan (Master WQMP) in anticipation of future land redevelopment at the Resort. The Master WQMP includes the use of low impact development techniques in the project design to reduce the amount of storm water discharged to the ocean and improve the quality of discharged water.

Pollutant treatment and volume reduction BMPs suggested by the Master WQMP include porous pavement, percolation ponds, infiltration basins and bioretention swales. The implementation of the Master WQMP has a direct correlation with the success of the Resort’s storm water management practices and improvements in storm water runoff quantity and quality.

The Master WQMP is based on a long‐term development plan for the Disneyland Resort in order to accommodate the most practicable BMPs for the entire watershed and provide a more comprehensive and sustainable water quality program. Periodic updates of the Master WQMP (anticipated to take place every four to five years) will ensure that projected changes in land use through site development or significant redevelopment are taken into account.

Source control BMPs are based on the extensive list provided in this SWPPP. Site design and treatment control BMPs are based on the Orange County (OC or County) Drainage Area Management Plan (DAMP) prepared to comply with the Municipal Separate Storm Sewer System NPDES Permit (CAS618030) issued for north Orange County and the City. The DAMP and the City’s storm water treatment BMP requirements for development and significant redevelopment are met by the Disneyland Resort with an emphasis on a pre‐determined list of the most suitable BMPs for the existing constraints on a Disneyland Resort site that is extensively developed and presents limited opportunities for certain BMPs. As a result, the Master WQMP includes a more comprehensive, holistic, consistent, and methodical approach to the selection and implementation of site design and treatment control BMPs for the Disneyland Resort to comply with land development related storm water quality.

The development and significant redevelopment projects for the Disneyland Resort are known approximately three to five years out, sometimes longer, and are implemented in phases. The Master WQMP takes into account these numerous projects and anticipates the selection of BMPs most suitable for the long‐range plans and development. The benefit to the City is having their Master WQMP be equivalent to a “conceptual” WQMP that includes BMPs proposed for the entire site and is the basis of future detailed project‐specific WQMPs. Secondary benefits to the Disneyland Resort and the City are a streamlined and more effective permit approval process and a long‐term water quality planning process.

The Resort has implemented WQMP development and redevelopment projects with the specific intent of reducing and controlling pollutants anticipated from the on‐going operation and use of the developed property. The three types of BMPs include: source control (both structural and non‐structural); low impact design BMPs, which includes permanent design features embedded into the property that generate lower pollutant discharges and flows during storm events; and treatment control BMPs, which are structural systems designed to remove pollutants. The BMPs are selected to address site specific pollutants based on the use category (e.g., restaurant, parking lot).

NPDES Storm Water Pollution Prevention Plan (SWPPP)
DLR NPDES SWPPP Revision 09 PAGE 45
In order to follow through with these efforts, Disneyland Resort has been committed to designing environmentally friendly practices for the development of new attractions and the redevelopment of existing attractions throughout the facility. More recently, the Resort has concentrated its efforts to minimize non‐point source pollution from construction and post‐construction of new areas and attractions throughout Disneyland Resort and specifically with the expansion of Disney California Adventure.

Newer installations include porous pavement, percolation ponds, downspout filtration, automatic rain diversion systems, inline clarifiers, grease interceptors, and bioretention swales. Many of these measures were included in the construction of the following facilities:

DISNEYLAND RESORT CENTRAL BAKERY – Disneyland Resort commissioned a new 10,000 square foot central bakery facility in March 2009 which produces 90% of all baked goods for their restaurants, hotels, and stores. The facility consolidated most of the Resort’s baking operations into one location that has been designed and built with state of‐the‐art improvements, including daylight systems, energy star equipment, demand response and peak load shifting technologies, landscape infiltration elements, and sustainable pavement solutions. Bioswale landscape elements and sustainable porous pavement solutions were designed to remove silt and pollutants from surface runoff water, and are instrumental in recharging groundwater by capturing storm water and allowing it to seep into the ground. Downspouts from roof drains are also fitted with Hydro FloGard® Downspout Filters designed to collect particulates, debris, metals, and petroleum hydrocarbons that accumulate on rooftops from atmospheric deposition prior to discharge to landscaped bioswales.

The central bakery’s retention and pervious surfaces are designed to infiltrate storm water. Pollutant removal occurs through the infiltration of runoff and absorption of pollutants to the soil and vegetation, and is designed to infiltrate within 48 to 72 hours. This BMP provides for nearly 100% removal efficiency of the entire water volume.

DISNEYLAND RESORT SURFACE PARKING LOT – This project consisted of the construction of approximately 25.5 acres of parking area (4,247 regular spaces and 84 handicapped spaces) on which porous pavement, a permeable pavement surface with an underlying stone reservoir that temporarily stores surface runoff before infiltrating into the subsoil, was installed instead of traditional pavement, allowing parking lot runoff to infiltrate directly into the soil as part of an engineered water quality treatment design. Porous pavement was significantly more expensive than traditional asphalt.

The undeveloped project area predominantly drained towards an existing detention basin. To accomplish effective surface drainage, the site was raised approximately five feet which facilitated 80% of the site to drain back toward the detention basin. The remaining 20% drains into an infiltration basin. Any storm water runoff from this newly developed area flows to either the existing detention basin or the infiltration basins channeled through v‐shaped bioswales that were designed to be hydraulically capable of handling both the first flush and the larger 100‐year storm event.

The storm water treatment BMP features at this site are the following:

Bioswales/V‐channel (Vegetative Swales): Approximately 4,000 linear feet of bioswales are used throughout the site for cleaning storm water before entering either a detention basin or infiltration basin for infiltration. They are also the principal storm water drain system for higher flows. These swales are part of a treatment train for pollutant removal prior to infiltration.

Infiltration Basins and Trench: An infiltration basin and trench with a combined retention capacity of approximately 0.95 acre feet lies along Harbor Boulevard just north of Convention Way. These BMPs ENVIRONMENTAL POLICY/PROCEDURE (Water) Doc #: SWPPP – R09 The Disneyland®
Resort
NPDES Storm Water Pollution Prevention Plan (SWPPP)
DLR NPDES SWPPP Revision 09 PAGE 46
were designed to store and infiltrate the resultant runoff from the porous pavement that was not able to be stored in its subsurface gravel beds. In addition, two other infiltration basins are provided for an additional retention capacity of 0.50 acre feet. An easterly infiltration basin and trench were added to treat the runoff from the additional parking. The easterly infiltration basin has a capacity of approximately 0.195 acre feet.

Pervious Pavement: Approximately 20% of the developed site is pervious pavement designed to reduce runoff by allowing storm water to infiltrate through its porous surface into gravel beds below for storage and infiltration into the native soil.

Extended Detention Basin (existing): A sediment forebay was added to the existing detention basin in order to enhance sediment capture before runoff exits the basin into the City’s storm drain system. The existing detention basin is capable of retaining not only the first flush volume but the entire 100‐year runoff volume while metering out a quantity of flow designed to minimally impact the existing storm drain system along Harbor Boulevard. Treated water from the bioswales enters the sediment forebay and is allowed to fill to a depth of 1.5 feet before overflowing into the existing detention basin. Inlets and cleanouts have 1‐inch sumps designed for sediment capture.

DISNEY CALIFORNIA ADVENTURE BACK OF HOUSE BUILDINGS –The DCA Back of House is a network of buildings, exterior storage areas, and staging areas which for the most part are organized along a heavily used loop‐road. This collection of interior and exterior spaces provides the necessary framework to support the operation of the theme park. Storm water on the existing site previously sheet flowed to drains and catch basins located at local low points. Storm water was then conveyed by the private storm drain system to the city storm drain system. This project included the addition of four new buildings on already developed, mostly paved areas, resulting in very minimal increase of impervious foot prints.

The total area of the project was 2.0 acres, or 87,120 square feet, which includes buildings/structures, parking areas, and landscaped areas. The production kitchen was built with two loading docks fitted with an oil/sediment separator and equipped with rain diversion valves installed in vaults. Trash packers installed at this facility are large trash compactor units with 50 gallon clarifiers to capture hydraulic oil in the event of a line failure, and are also equipped with an independent rain diversion valve. These rain diversion systems allow for the discharge of runoff from the wash down wastewater, and first flush rainwater to be directed to the sanitary sewer. A rain gauge activates a rain valve that switches to discharge to the storm drain system after 1/10th of an inch of rainfall. Storm water from the loading docks is discharged into the swale for runoff treatment.

A grease interceptor and outdoor wash pads are also provided to prevent storm water pollution. These areas are covered and do not allow for rain water runoff to the storm drain system. The roof area for the production kitchen is 10,375 square feet (0.24 acres), the central maintenance facility roof area is 5,746 square feet (0.13 acres), the custodial multipurpose building roof area is 3,407 square feet (0.08 acres), and the roof area for the entertainment complex is 10,145 square feet (0.23 acres).

Runoff from these facilities is treated using the vegetated swale and pervious pavement infiltration.

Concrete walk areas in front of these facilities is about 1,177 square feet. It is engineered to drain to the adjacent pervious pavement at the cart parking stalls. Parking areas designated for vehicles to the west of these buildings incorporates 3,696 square feet of porous asphalt surfaces.

THE VILLAS AT DISNEY’S GRAND CALIFORNIAN HOTEL & SPA – The expansion of Disney’s Grand Californian Hotel & Spa included the addition of 200 guest rooms, 50 suites, two levels of underground parking, a pool, and pathways and driveways to the hotel. This expansion is known as The Villas at Disney’s Grand Californian Hotel & Spa. The total area of this project was 2.88 acres, of which 1.69 acres ENVIRONMENTAL POLICY/PROCEDURE (Water) Doc #: SWPPP – R09 The Disneyland®
Resort
NPDES Storm Water Pollution Prevention Plan (SWPPP)
DLR NPDES SWPPP Revision 09 PAGE 47
are the building and surrounding hardscape, and 1.19 acres are pervious ground with landscaped and planter areas. Portions of the roof were designed to drain to landscaped areas. The majority of the roof runoff is collected by downspouts and piped over to a vegetated swale which facilitates the treatment of storm water and promotes infiltration instead of direct discharge to the storm drain system. These swales are also the principal storm water drain system for higher flows and are part of a treatment train that also includes downspout filters for pollutant removal prior to infiltration.

A small portion of the roof that could not be directed to either landscape or the swale was piped to a dedicated Stormceptor® unit prior to discharge off site. The subterranean parking area was engineered to preclude storm water run‐on with a ribbon gutter at the ramp entrance, and the intercepted sheet flow is directed to a catch basin fitted with an Ultra‐Urban® inlet filter insert. Area drains within the parking lot that capture nuisance flow are directly connected to the sanitary sewer so as to avoid pumping polluted water to the storm drain system.

CARS LAND – In June 2012, Cars Land was unveiled at Disney California Adventure. This redevelopment project includes new attractions, dining areas, and shopping venues. The 12‐acre project included new themed buildings, roads, bridges, tunnels, waterfalls, and landscaped areas. Cars Land is the largest area treated by storm water BMPs within the Disneyland Resort. Great consideration was given in order to incorporate the latest and most effective storm water treatment technologies into this project. The impervious area of the original Timon Parking Lot, which was redeveloped for Cars Land, has been replaced with landscaping and pervious areas allowing for storm water infiltration and treatment.

In addition, this project site has numerous BMPs designed to retain or capture and infiltrate treated storm water runoff allowing for replenishment of shallow groundwater aquifers. The many guests who visit this new land will never know that the BMPs collectively treat 96.3% of the project area. The remaining 3.7% of the project footprint was not treated because it was part of a right of way owned by a 3rd party utility company. All of these attractions and sites include post construction features that maximize pervious areas, treat and infiltrate storm water, and reduce or prevent the discharge of pollutants to the public conveyance system.

The strategy just presented can be summarized as follows: By selecting the most appropriate combination of final BMPs for each project and simultaneously considering the entire Resort’s redevelopment projects included in the Master WQMP, storm water management and development can both be effectively maximized.

8.2 Adopt‐A‐Channel Program
Disneyland Resort discharges storm water to the Anaheim Barber City (ABC) Channel which is a 45,658‐ foot concrete lined storm drain system designed to reduce flooding in multiple cities across Orange County. The channel has been impacted by debris from city streets as well as illicit dumping, overgrowth of vegetation, and reoccurring vandalism of structures with graffiti. For decades, the Disneyland Resort has incorporated structural and non‐structural BMPs into its operations that are specifically designed to reduce, and in many cases eliminate, potential pollutants, resulting in a higher quality of water being discharged through the onsite storm drain system to the ABC Channel which is heavily impacted by debris and pollutants.

In 2012, Disneyland Resort approached the Orange County Public Works Department (OC Public Works) to seek a partnership for this conceptual pilot program proposed to include the field resources of OC Public Works and the outreach resources of the Disneyland Resort to adopt portions of the ABC Channel and provide cleaning and maintenance of the channel on a routine basis.

Disneyland Resort spearheaded the initiation of this program with the adoption of a two‐mile section of the channel from the Disneyland Resort at Ball Road extending south towards the Bolsa Chica Ecological Reserve at Palmwood Drive within the Orange County Flood Control District’s right of way.

The Disneyland Resort engaged the Orange County Sheriff’s Department to partner with the project team to enter data into the Sheriff’s “Tracking Automated Graffiti Reporting System” (also known as TAGRS).

This system is a mobile application designed to serve the needs of law enforcement agencies to identify offenders and reduce graffiti in order to improve the quality of life for the residents.

Waste within the channel has shown significant improvements which includes trash and debris removal, and weed abatement in the Orange County Flood Control District’s right of way using mechanical means (herbicides or algaecides are not used). Graffiti removal has included thousands of square feet abated by covering with water based paint. Vandalism in this channel has decreased by almost 90% since July 2013.

The Disneyland Resort generates an annual report for the period of July 1 through June 30 of the previous year, and submits it to the Director of OC Public Works.

Waste removed from the channel includes mostly household items and general trash and debris.  Large quantities of waste associated with graffiti activities are also routinely removed.  Below is a list of the most common items removed:
 Empty aerosol spray cans     Alcohol containers    Wood fencing  Paper    Lawn furniture    Blankets
 Fast food containers    Footballs      Newspapers Flood channels impacted by debris can pose high risks to residents and entire communities along the right‐of‐ways during storm events and can result in displacement of occupants as well as home damage.

They are also breeding grounds for insects that thrive on wet environments where ponding is prevalent and can drive an increase in illnesses associated with exposure to mosquitoes in epidemic outbreaks like the West Nile Virus (WNV). Long‐term impacts include devastating disruptions in the natural habitats of wildlife in sanctuaries and reserves that are downstream of may flood control channels. The ABC Channel discharges directly into the Bolsa Chica Ecological Reserve which has been designated by the California Department of Fish and Wildlife as a nature reserve to protect coastal wetlands containing resident threatened and endangered species.

Reducing tagging and other illicit activity within and around the flood control channels restores pride among communities and deters the reoccurrence of new graffiti being applied as their displays are short lived. Having crews inspect sites on a weekly basis and remove graffiti as soon as it is found has proven to reduce the reapplication of new tags with a high success rate.

One of the main goals of the adopt‐a‐channel program is for other cities and public and private organizations to take this model and apply it to their own flood channels. To facilitate future implementation by others, the Disneyland Resort worked closely with each of the stakeholder government agencies from the inception of the program to design a streamlined approach to its implementation. Areas reviewed for streamlining include municipal program development, city permitting and approval, public and private adoptee application process (to simplify it), and routine and reoccurring maintenance scheduling. Also important was the development of waste collection and disposal protocols to validate that all applicable laws are followed, implementation of a sustainable on‐going program through permitted and fully insured contractors, uniformity in paint selection for concrete lined flood channel graffiti abatement, control of weeds where necessary, protection of wildlife, beneficial vegetation, and sediment forebays, and a safe environment for crews to work in. All of these parts were ENVIRONMENTAL POLICY/PROCEDURE (Water) Doc #: SWPPP – R09 The Disneyland®

packaged into a comprehensive working document that is intuitive and easy for cities as well as the general public to follow and implement.

Partnerships with government agencies, like the City of Anaheim, OC Public Works, and the Orange County Sheriff’s Department, and non‐profit organizations, including the OC Conservation Corps, Wyland Foundation, and Bolsa Chica Conservancy, are fundamental in the success of programs like these as cities are often unable to fund and sustain projects with accelerated maintenance frequencies specifically focused on deterring taggers and illicit dumping. The Disneyland Resort is committed to environmental protection and in this case, specifically on the water we discharge from our theme parks.

8.3 Non‐Storm Water Diversion to Sanitary Sewer
In 2012, Disneyland Resort approached the Orange County Sanitation District (OCSD) and the Orange County Water District (OCWD) to develop a multi‐year dry weather flow diversion plan for the discharge of nightly washdown water from On Stage areas and limited nuisance flows from the Rivers of America to the sanitary sewer. This collaboration was not only significant in the Disneyland Resort’s approach to non‐storm water management but timely as it correlated with the expansion of the OCSD Groundwater Replenishment System (GWRS). The OCSD had just announced their second phase of development in January 2012, which is scheduled to be completed in September 2014 and which will have a daily production capacity of 100 million gallons per day. The current system has a production capacity of 70 million gallons of water per day and a total production of 23.5 billion gallons per year.

Recognizing that the water discharged from the Resort was of higher quality coupled with the OCSD’s need for additional source water for the GWRS, the project was fully supported by the OCSD, OCWD, and the RWQCB. The Resort’s program is phased over a five‐year project term with the larger volume discharge points being scheduled first. At the end of 2012, the largest of the pump stations came on line which diverts approximately half of the total non‐storm water volume generated at the Disneyland Resort. In doing so, the Disneyland Resort has reduced the amount of permitted non‐storm water originally discharged to the ocean.

The GWRS takes highly treated wastewater that would have otherwise been discharged to the Pacific Ocean and purifies it to near‐distilled quality water. This is done with advanced techniques consisting of microfiltration, reverse osmosis, and ultraviolet disinfection with hydrogen peroxide. Water is then used to replenish the Orange County groundwater basin and to prevent seawater from contaminating the county's groundwater supplies.

Non‐storm water discharge diversion is being achieved through the design and construction of fully automated, redundantly equipped pump stations that divert non‐storm water to the sanitary sewer system. These pumps are turned off by an automatic rain sensor during rain events following an initial discharge of storm water, allowing it to bypass the pump station and flow directly into the storm drain system. Non‐storm water discharges to the GWRS meet the requirements of the Resort’s Permit and far exceed the conditions and requirements in OCSD’s Special Purpose Discharge Permit.

4 SubWatershed BMP Plan

4.1 Introduction
A sub‐watershed infiltration BMP (sub‐watershed BMP) is an LID BMP that is: (1) located within the Disneyland Resort, (2) designed to capture and treat water at the sub‐watershed scale, and (3) not necessarily located within the footprint of a particular project. The use of sub‐watershed BMPs can serve as a compliance option for priority projects to meet the new development and significant redevelopment program requirements of the Municipal Permit, the Model WQMP, and City requirements in a manner consistent with Resort‐specific opportunities and constraints. Sub‐watershed BMPs allow the Resort to achieve equal or better water quality benefits in comparison to LID BMPs within each project footprint by allowing infiltration BMPs to be located where conditions are more favorable for infiltration and where the BMP can capture runoff from a larger tributary watershed. As discussed in Section 3.5, when a sub‐watershed BMP is operational and has capacity available, a constrained project may choose to meet LID BMP requirements by participating in a sub‐watershed BMP rather than implementing LID BMPs within each project footprint.

In order to effectively implement sub‐watershed scale LID BMPs at the Resort, this “Sub‐Watershed BMP Plan” (Section 4 of this Master WQMP and associated appendices) has been developed. This Sub‐ Watershed BMP Plan provides guidance and criteria for: (1) identifying high priority sub‐watershed BMP opportunities (Section 4.2), (2) developing sub‐watershed BMP projects (Section 4.3), and (3) utilizing and tracking sub‐watershed BMP capacity for projects that rely on these BMPs for compliance (Section 4.4). As sub‐watershed BMPs are approved, constructed, and become operational, these BMPs will be incorporated into this section as the “living” portion of the Master WQMP Project Tracking Sheet (Appendix 5‐A).

4.1.1 How to Use this Section
This section can be used for a number of purposes including:
 Identifying and prioritizing sub‐watershed BMP opportunities (Section 4.2);  Developing sub‐watershed BMPs as standalone projects or as part of proposed development projects (Section 4.3); and
 Utilizing sub‐watershed BMPs to meet LID BMP requirements for a project (Section 4.4), including determining if sub‐watershed BMPs with capacity are available and documenting participation in these BMPs.

4.1.2 Regulatory Basis
The Orange County Municipal Permit and Model WQMP recognize that specific considerations apply to individual redevelopment projects within a larger site (Permit XII.B.2.a, Model WQMP 7.II‐1.2) and that numeric sizing criteria for a given redevelopment project are applicable only to the additional or replaced areas created by the project, rather than the entire site as a whole. In the case of the Disneyland Resort Master WQMP
Section 4: Sub‐Watershed BMP Plan
LaRoc Environmental 4‐2 December 2014 –Final
Disneyland Resort, each redevelopment project represents a portion of the existing Resort site; therefore, numeric LID BMP sizing requirements apply only to the new or replaced areas.

The Model WQMP also recognizes that certain conditions (e.g., multiple benefits, groundwater recharge, space restrictions, redevelopment opportunities, economic considerations) may favor the implementation of LID principles and LID BMPs at a broader scale beyond the boundaries of a specific development project through the use of “regional or sub‐regional” LID BMPs (Model WQMP 7.II.2.4.3.2).

The large scale of the Disneyland Resort site presents an opportunity to use an approach that provides on‐site compliance solutions through sub‐watershed BMPs within the Resort site.

Finally, the Municipal Permit recognizes that there are constraining factors, including space restrictions associated with redevelopment projects, in‐fill projects, and high density development that create opportunities to incorporate LID principles into alternative programs including sub‐watershed management approaches (Permit XII.C.5). Redevelopment at the Resort can be highly space constrained, so implementing sub‐watershed scale planning can help achieve additional LID benefits through retention and infiltration at the sub‐watershed scale rather than progressing through the hierarchy of LID options to the use of biotreatment at the project‐scale.

In summary, when appropriately implemented, a sub‐watershed BMP located within the Resort site and downstream of the development or redevelopment project(s) of interest can be used to fully meet LID BMP requirements in a manner consistent with the Model WQMP and Municipal Permit, and will provide equivalent stormwater treatment and water quality benefits. This compliance pathway is introduced in Section 3.5 of this Master WQMP and is supported with guidance and criteria presented in this section. This approach was conceptually approved by the Santa Ana RWQCB in the Disneyland Resort Sub‐Watershed Best Management Plan (BMP) Work Plan Acceptance Letter dated April 16, 2014 (Appendix 4‐C).

4.2 Identifying and Prioritizing SubWatershed BMP Opportunities Developing sub‐watershed BMPs requires conducting proactive sub‐watershed scale site planning and feasibility analyses of potential sub‐watershed BMP locations. This section provides guidance for identifying and prioritizing sub‐watershed BMP opportunities at the Resort. The purpose of this guidance is to assist Resort Cast Members and Resort contractors in identifying locations that are feasible for infiltration of stormwater on the Resort site and would provide strategic value in meeting LID requirements for future developments. By virtue of their sub‐watershed‐scale application, these locations could be selected to accept runoff from multiple redevelopment projects. After the potential locations are identified and prioritized, the high priority locations could be reserved for sub‐watershed BMPs, which would be implemented prior to the first redevelopment project within the sub‐watershed area that relies on them for compliance. The timing and sequencing of actual construction of sub‐ watershed BMPs would be determined by Resort Cast Members depending on development projections and other factors. An example of project sequencing and managing sub‐watershed BMP capacity is illustrated in Figure 4‐1.

4.2.1 Subwatershed BMP Identification and Prioritization Process Identification and prioritization of sub‐watershed infiltration BMPs can be done on an opportunistic, project‐by‐project basis, or may in the future be conducted as part of a structured planning process that could incorporate the following general steps:

1. Identify potential forecasted redevelopment projects within a planning time period as determined by the Disneyland Resort, including locations of these projects and potential project footprints and attributes. Each of the identified projects should be evaluated to determine the footprint area, imperviousness, and other land use characteristics needed to determine: (1) how much LID DCV each would require, (2) whether each would be a constrained site that would benefit from a sub‐watershed BMP, and (3) when a sub‐watershed BMP would need to be completed in order to meet the needs of each project.

2. Conduct a proactive sub‐watershed‐scale site planning analysis that identifies opportunities and constraints for sub‐watershed BMPs. This analysis would include review of forecasted development locations, underground utility corridors, existing building foundations, drainage pathways, Resort use (e.g. on stage, backstage), existing infrastructure, and other factors that relate to feasibility of stormwater infiltration. For each of the candidate sub‐watershed scale BMP locations identified, an analysis considering the feasibility of siting the sub‐watershed scale BMP should be conducted following the infiltration feasibility guidance provided in Section 3.6 and the sub‐watershed BMP design guidance provided in Section 4.3. This includes, but is not limited to, Resort maps, building plans, utility maps, topographical information, soil characteristics, storm drain locations, and input from Resort Cast Members on additional opportunities and constraints.

3. Based on the site planning analysis, identify locations for sub‐watershed BMPs that would be feasible and provide strategic value. These locations would be downstream of forecasted redevelopment projects and feasible for construction of an infiltration system with capacity equal to at least minimum storage volumes for the participating redevelopment projects. This step should include estimation of the type of the underground storage capacity available at the site so that it can be determined how much tributary area can be addressed in each BMP location.

4. Prioritize these sub‐watershed BMP opportunities relative to their strategic value and feasibility.

As part of this step, it may be necessary to develop conceptual designs of these facilities to the level of detail adequate to evaluate their feasibility, capacity, and cost. Conceptual designs should be developed consistent with the design guidance provided in Section 4.3.

For each priority project, Appendix 4‐A may be used to assist with the evaluation of sub‐watershed BMP opportunities and constraints. If high priority sub‐watershed opportunities are identified but not immediately implemented, Environmental Affairs will keep an inventory of potential locations so that these sites can be reconsidered in the future and potentially earmarked for this purpose.

4.2.2 SubWatershed BMP Prioritization Categories
Each of the potential sub‐watershed infiltration BMPs identified through the process above can be categorized as “high”, “medium”, or “low” priority to assist with selecting the most preferential sub‐ watershed BMPs.
 High priority locations are considered preferential and strategic due to the development site characteristics and the proposed location of the sub‐watershed BMP.  Characteristics of high priority locations include: adequate space for BMP within the proposed development project, soils with good infiltration capacity, do not pose a risk to adjacent structures/utilities, can readily tie into the storm drain system, and can provide treatment capacity for multiple up‐ stream priority projects.
 Medium priority locations may have certain factors that make them less desirable or strategically important than high priority locations.  For example, they may have a constrained available BMP footprint due to land use plan and/or proximity to building foundations/utilities, a more challenging connection to existing storm drain system, or not located at an opportunistic Evaluating Opportunities for Sub‐Watershed BMPs
when Planning for a Redevelopment Project
The early planning stages of a priority development project are a good time to evaluate whether a sub‐watershed BMP could be implemented as part of the project.  The redevelopment project and the sub‐watershed BMP could be implemented as part of the same permitting and design action.

The sub‐watershed BMP could address the project footprint in addition to developing surplus capacity for future projects with similar land uses.

location to provide treatment for multiple upstream priority projects. Some of these locations may still be viable, but are considered medium priority due to these challenges.  Low priority locations are defined by significant constraining factors that make them likely infeasible.

4.3 SubWatershed BMP Development Process
Once the potential location for a sub‐watershed BMP has been identified and selected, there are eight main steps that need to be taken in order to effectively design and implement a sub‐watershed BMP, including the submittal of a Preliminary and a Final Project WQMP that documents the sub‐watershed BMP. Table 4‐1 describes each of these steps and provides references to the locations in this Master WQMP where additional guidance is provided.

This process and the following sub‐sections are not intended to provide exhaustive design guidance.

Resort Cast Members and contractors working on sub‐watershed BMPs will need to incorporate site‐ specific information, engineering methods, and professional design judgment to develop designs that are safe, effective, and efficient for a given site. The criteria and guidance presented in this section is intended to describe those features that are most important for the sub‐watershed BMP to serve its water quality function and comply with conditions of use for sub‐watershed BMPs.

4.3.1 Step 1: Preliminary Site Assessment
The first step in the sub‐watershed BMP development process is to conduct a preliminary site assessment to identify potential locations for implementation of sub‐watershed BMPs, evaluate infiltration feasibility, approximate infiltration rate, and determine the project attributes. Guidance for prioritizing sub‐watershed BMP locations is provided in Section 4.2 and introduces the factors that should be evaluated. Guidance for conducting a site assessment is provided in Section 3.3 and 3.6 relative to BMP selection methods and feasibility criteria.

4.3.2 Step 2: SubWatershed BMP Conceptual Sizing and Design The sub‐watershed BMPs implemented at the Resort will typically be underground infiltration facilities (TGD Fact Sheet INF‐7) because of surface space constraints and the need to tie into sub‐surface storm drains at sub‐watershed BMP locations. Fact Sheet No. 1, located in Appendix 4‐B of this Master WQMP, provides a Resort‐specific BMP fact sheet for underground infiltration BMPs, which has been modified from BMP Fact Sheet INF‐7 (Page XIV‐44) in the TGD. The criteria in this fact sheet are considered to be recommended design criteria for all sub‐watershed BMPs implemented at the Resort.

If site‐specific conditions or factors require deviations from these criteria, these deviations can be approved with appropriate supporting documentation, at the discretion of the project engineer and the City of Anaheim.

Underground infiltration facilities are typically pre‐fabricated or cast‐in‐place structures, such as pipes, vaults, or modular structures, with open bottoms that are used to store runoff and percolate stormwater into the subsurface. The specifications of each underground infiltration BMP configuration vary based on site constraints, feasibility and the type of design developed; however, the following design features are generally common across the proposed sub‐watershed BMPs at the Resort:
 Diversion structure (see below for details);
 Pre‐treatment BMP with access for maintenance (see below for details); Disneyland Resort Master WQMP
Section 4: Sub‐Watershed BMP Plan
LaRoc Environmental 4‐8 December 2014 –Final
 Underground structural storage features to provide retention storage (pipes, chambers, vaults, modular systems, gravel reservoir);
 Bedding layer below the storage layer for structural purposes and/or to provide a filtering layer for sediments;
 Compacted backfill above the structural elements to provide separation between the top of the infiltrating BMP and the finished surface above (parking lot, sidewalk, roadway, etc.);  Inspection ports or similar design features to provide verification of continued system performance and identify needs for maintenance; and
 Access ports, if feasibility, to allow for periodic removal of sediment.

Selecting the Size of a Sub‐Watershed BMP
Sub‐watershed BMPs will typically be implemented as retrofit projects, based on the opportunities at a site. As such, the sub‐watershed BMP does not necessarily need to be sized for full DCV of the entire tributary watershed; it simply needs to be sized to generate the amount of capacity that is anticipated to be used by future development projects. The sizing of a sub‐watershed BMP should be determined based on:

1. Available area (i.e., how much volume can be provided?)

2. Tributary area (i.e., how much water is there to capture?) Infiltration of full diverted storage volume

3. Demand for sub‐watershed BMP capacity (i.e., how much development is expected to occur within the sub‐watershed or in other constrained locations that may require BMP Exchange credits?)
The selection of an optimal size of a sub‐watershed BMP can be an iterative process that balances the three sizing factors listed above through achieving a large enough capacity to meet development project demands without inflating the size to unnecessarily occupy the entire available area when the full capacity will never be utilized. For example, if the capacity created by the total available BMP footprint area far exceeds the required capacity from the tributary area and additional demand, the oversized BMP will never be fully utilized and will not be cost‐efficient. Figure 4‐3 presents an example methodology that can be followed when iteratively sizing sub‐watershed BMPs with additional descriptions of each of the steps included below.

LaRoc Environmental 4‐10 December 2014 –Final
Step A: Determine the initial available sub‐watershed capacity:

1. Determine the potential footprint (sq ft) that may be used for storage of stormwater runoff.

This does not include the space that may be required backfill, structural components, and required separation distances between underground storage modules/pipes/vaults.

2. Evaluate the volume available for storage (cu ft). This can be accomplished by determining a depth of stormwater that will be stored by setting a desired draw down time or can be obtained from prefabricated structure specifications. In both of these cases, the volume available is representative of the pore space only and does not include the gravel/rock drainage media.

Step B: Convert the volume capacity in the sub‐watershed BMP to equivalent treatable development area using the method below:

1. First, use the worksheet and method included in Fact Sheet No. 2, located in Appendix 4‐B, to estimate the capture efficiency of the provided volume. This is a function of the tributary area, storage volume, and drawdown time. The result is equal to the percent of long term runoff volume from the entire tributary sub‐watershed that is captured by the sub‐watershed BMP.

2. Next, the following equation can be used to determine the equivalent developable area that can be treated by a sub‐watershed BMP:

ATreat = ATributary × (Watershed % Capture) / 80% Eqn 5.

Where:

ATreat = total treatable area (sq ft)
ATributary = total area tributary to the sub‐watershed BMP (sq ft) Watershed % Capture = as calculated in Step B.1
If the imperviousness of the tributary area is unknown at the time of sub‐watershed BMP sizing, a conservative estimation of 100% imperviousness should be used.

Step C: Estimate the capacity that will be needed in the sub‐watershed BMP by estimating the footprint of development anticipated to occur within the tributary sub‐watershed as well as the amount of BMP credits anticipated to be needed for alternative compliance through the BMP Exchange. Both capacity and demand are expressed in terms of area of development.

Step D: Compare the total treatable area (ATreat) from Step B to the estimated demand from Step C.  If the total treatable area by the BMP is relatively well‐matched to the amount of development demand expected, then the size is approximately appropriate.  If the total treatable area by the BMP is much smaller than the anticipated development demand, then the storage volume of the sub‐watershed BMP should be increased to the extent Disneyland Resort Master WQMP
Section 4: Sub‐Watershed BMP Plan
LaRoc Environmental 4‐11 December 2014 –Final
feasible to provide additional capacity for treatment. If it cannot be increased by a meaningful margin, then it may not be worthwhile to pursue this project further.  If the capacity of the sub‐watershed BMP is greater than anticipated development demands, the size of the BMP can be reduced. This can help reduce construction and maintenance costs.

Step E: Once an acceptable sub‐watershed BMP capacity has been established, the design of the facility (Section 4.3.2) should be determined and the Preliminary or Final Project WQMP for the sub‐watershed BMP should be prepared (Section 4.3.3 or Section 4.3.6).

Diversion Structure Design Requirements
The diversion structure located up‐gradient from a sub‐watershed BMP is intended to divert water from the main Resort storm drain system that is to be treated into the sub‐watershed BMP, while allowing higher flows to bypass the BMP. The design flow rate for the diversion structure should be set using flow‐based BMP sizing methods such that it provides at least the equivalent long term capture efficiency of the sub‐watershed BMP for its entire tributary area. The worksheet and method included in Appendix 4‐B, Fact Sheet No. 2, should be used to estimate the capture efficiency of the sub‐watershed BMP. Next, Appendix 4‐B, Fact Sheet No. 3, presents a Resort‐specific version of TGD Worksheet D to assist with determination of the design flow rate necessary to achieve at least this capture efficiency.

Engineering calculations and design of diversion structures to achieve the target diversion rate must be conducted as part of the BMP design. Diversion structures must be designed as “cutoff” diversions such that no water should be allowed to bypass the diversion structure until the design flow rate is exceeded.

Pre‐Treatment BMP Requirements (Type and Size)
Pre‐treatment systems are strongly recommended for sub‐watershed BMPs to reduce sediment loading (including fine sediment removal), thereby reducing the risk of clogging that may reduce infiltration rates over time, ensuring BMP longevity, avoiding premature failure and reducing maintenance frequencies. Any of the biotreatment and/or pretreatment/gross solids removal BMPs shown in the TGD Appendix XIV (BMP Fact Sheets), or equivalent alternatives, can be used as pre‐treatment. The design flow rate for flow‐based pre‐treatment structures up‐stream of the sub‐watershed BMPs should be equivalent to that determined for the diversion structure as identified above.

Design Infiltration Rate
The design infiltration rate for sub‐watershed BMPs must be based on site‐specific testing under the supervision of a licensed geotechnical professional, with an appropriate factor of safety applied as part of the preliminary or comprehensive site assessments (Section 4.3.1 or Section 4.3.4). TGD Appendix VII should be used to guide infiltration testing and TGD Worksheet H should be used to aid with selection of an appropriate factor of safety. The design infiltration rate influences the capture efficiency of a sub‐ watershed BMP and must be used in calculating the drawdown time of the BMP for sizing and capture efficiency calculations.

4.3.3 Step 3: Prepare and Submit Preliminary Project WQMP for the SubWatershed BMP The Preliminary Project WQMP for the sub‐watershed BMP should contain a level of detail adequate to clearly demonstrate that the sub‐watershed concept and the BMP’s working assumptions will Disneyland Resort Master WQMP
Section 4: Sub‐Watershed BMP Plan
LaRoc Environmental 4‐12 December 2014 –Final
reasonably fit within the proposed site and will provide the necessary level of capacity. Generally, the following should be shown:
 Sub‐watershed BMP location and tributary area delineation;  Development project characteristics and location;
 Footprint, conceptual cross section, and design volume shown on plans/exhibit;  Results of site assessment and basis for working design parameters, including design infiltration rate;
 Calculation of sub‐watershed BMP capacity as developable acreage; and  Conceptual flow paths and routing shown on plans/exhibit.

The Preliminary Project WQMP should be submitted using the Resort’s Project WQMP Template provided in Appendix 3‐C to satisfy the City’s Project WQMP requirements. If the project is being installed entirely as a retrofit (and not part of a priority development project), then only the relevant sections of the Resort’s Project WQMP Template need to be completed. The completed Preliminary Project WQMP along with BMP location map is forwarded to Environmental Affairs to review for compliance with this Master WQMP and logged into the Resort’s Master WQMP Project Tracking Sheet and BMP Exchange Spreadsheet (Section 4.3.8). Environmental Affairs will use the Preliminary Project WQMP to provide a quality check on the project’s BMP selection, identify, verify and track any BMP Exchange credits or debits, and if approved, Environmental Affairs will return it to the project engineer with an updated Master WQMP Project Tracking Sheet for submittal to the City for review.

Preferably, the Preliminary Project WQMP for the sub‐watershed BMP should be prepared and forwarded to Environmental Affairs as early as possible in the design stage before extensive resources are used to finalize sub‐watershed BMP selection and prepare project design plans. A Preliminary Project WQMP can be prepared during the advance conceptual stage of a project or in conjunction with less than or 30% design plans. Internal review of the Preliminary Project WQMP by Environmental Affairs is critical in order to confirm the BMP credit “banking” and to minimize any City approval delays.

4.3.4 Step 4: Conduct Additional Site Assessment to support Final Design A comprehensive site assessment should be conducted to obtain any additional information needed to support the final sub‐watershed BMP design and preparation of the Final Project WQMP for the sub‐ watershed BMP. Some information may have been collected during the preliminary site assessment (Section 4.3.1), in which case the accuracy should be verified and incorporated in the final design. This additional site assessment information may include, but is not limited to, infiltration rate, final grading, sub‐watershed BMP capacity, and connections to the storm drain system.

4.3.5 Step 5: Develop Final Sizing and Design of SubWatershed BMP The sizing guidance in Section 4.3.2 should be used to verify and/or update the capacity and sizing of the sub‐watershed BMP following the site assessment conducted for final design. At the final design phase, construction‐ready details and plans for each of the sub‐watershed system components should be provided, including the diversion structure, pre‐treatment, storm drain connection, and the sub‐ watershed BMP itself.

Disneyland Resort Master WQMP
Section 4: Sub‐Watershed BMP Plan
LaRoc Environmental 4‐13 December 2014 –Final

4.3.6 Step 6: Prepare and Submit Final Project WQMP for the SubWatershed BMP The Final Project WQMP for the sub‐watershed BMP requires additional detail, commensurate with final design documents that will be issued for construction and implementation. In addition to the elements that need to be included in the Preliminary Project WQMP (Section 4.3.3.), the following additional elements are required for the Final Project WQMP:
 Verification or adjustment of preliminary assumptions made for the Preliminary Project WQMP – results of additional site assessment;
 Full design details and specifications;
 Project grading and drainage plans, drawn to scale and no less than 24X36” shall be included;  Current version of the BMP Exchange Spreadsheet (Section 5); and  O&M plan, including activities, responsibilities, and commitments to perpetual maintenance.

Additional information may need to be provided at the discretion of the designer and the reviewer.

Final sub‐watershed BMP design and sizing is based on the Preliminary Project WQMP when greater than 60% and/or 90‐100% design plans for the project are completed. Final sub‐watershed BMP design and sizing may change slightly based on new information but should conform to the City’s requirements and the methodology presented in this Master WQMP.

The Final Project WQMP for a sub‐watershed BMP project must use the Resort’s Project WQMP Template (Appendix 3‐C) in order to receive approval. The draft of the Final Project WQMP, as prepared for submittal and approval by the City of Anaheim, must be routed internally for concurrence by the various stakeholders. The “internal use only” cover to the Resort’s Project WQMP Template in Appendix 3‐C includes the signature blocks for the stakeholders that must approve the scope of the WQMP and BMPs. The project manager/engineer should route the draft Final Project WQMP to the distribution list and consider others, as appropriate for the project type, from the suggested distribution list at the bottom of the cover page. The “internal use only” cover with signatures should be removed from the Final Project WQMP prior to submittal to the City, but included in the Environmental Affairs file copy. At minimum, approval is required from:
 DLR Engineering Services,
 DLR Environmental Affairs, and
 DLR Architectural and Engineering.

4.3.7 Step 7: Install SubWatershed BMP to Meet Conditions of Approval Following approval of the Final Project WQMP, the sub‐watershed BMP should be constructed under the supervision of Facilities Asset Management per the plans and specifications that were approved in the final document. The post‐construction inspection and verification activities should also be conducted to document the sub‐watershed BMP as‐built condition. In addition, operations and maintenance activities should be scheduled and initiated.

Disneyland Resort Master WQMP
Section 4: Sub‐Watershed BMP Plan
LaRoc Environmental 4‐14 December 2014 –Final

4.3.8 Step 8: Incorporate Approved and Constructed Project WQMPs into Master WQMP The Master WQMP Project Tracking Sheet is maintained by Environmental Affairs and is used to track project review, routing and approvals, and to keep an inventory of all existing and proposed LID and treatment control BMPs. The Master WQMP Project Tracking Sheet also tracks all BMPs added to the “BMP Exchange”, debits by Resort projects participating in sub‐watershed BMPs and/or the Resort BMP Exchange, and available credits for constrained projects. The updated Master WQMP Project Tracking Sheet and BMP Exchange Spreadsheet are found in Appendix 5‐A.

The Master WQMP Project Tracking Sheet and BMP Exchange Spreadsheet are updated each time a Preliminary Project WQMP is received and approved by Environmental Affairs for each development/ redevelopment project. The Resort sub‐watershed BMP map(s) are updated periodically, preferably every six to twelve months.

The Master WQMP Project Tracking Sheet serves to update the City of all development and redevelopment BMPs (proposed and existing) and is submitted with the Preliminary Project WQMP by the project engineer as part of the preliminary permitting packet.

The Master WQMP Tracking Sheet and BMP Exchange Spreadsheet are also updated with the sub‐ watershed BMP data per the Final Project WQMP approved by the City and any time a BMP is upgraded, replaced, removed, or otherwise modified. Upon completion of construction, the project engineer or manager must complete the Project Close‐Out Form (Appendix 3‐E) in order to maintain an up‐to‐date BMP inventory. This process allows the Resort to have centralized clearinghouse for BMPs and stormwater quality management.

4.4 Utilizing and Tracking of SubWatershed BMP Capacity The utilization and tracking of sub‐watershed BMP capacity is managed by Environmental Affairs as part of the BMP Exchange Program. The surplus BMP capacity is tracked in square feet of area and by imperviousness of the total tributary area currently treated by the sub‐watershed BMP. As new projects are developed that utilize capacity of the sub‐watershed BMP, the available capacity in the sub‐ watershed BMP must be adjusted accordingly. Projects utilizing sub‐watershed BMPs must conform to the applicable requirements of Section 4.4.1 through 4.4.4, below.

4.4.1 Determining if a SubWatershed BMP is Available
A sub‐watershed BMP may only be used if it is constructed and operational prior to projects participating in it. As sub‐watershed BMPs are approved and constructed at the Resort, they are entered into the BMP Exchange Spreadsheet and added to the Master WQMP BMP Location Map (Exhibit 5‐A). These “living” documents will be updated by Environmental Affairs and can be used to evaluate whether a sub‐watershed BMP is downstream from a proposed development project and whether it has available capacity.

4.4.2 Conditions of Approval for Utilizing a SubWatershed BMP for LID Compliance A priority project that participates in a sub‐watershed BMP that is located downstream of the project and utilizes it as the compliance pathway (i.e., not alternative compliance) must demonstrate that all the following regulatory conditions of approval are met:

Disneyland Resort Master WQMP
Section 4: Sub‐Watershed BMP Plan
LaRoc Environmental 4‐15 December 2014 –Final

1. The sub‐watershed BMP has capacity for all participating development projects and capacity is of similar type land use. This is demonstrated by maintaining a current version of the BMP Exchange Spreadsheet (see Section 5) and showing that allocated capacity does not exceed available capacity.

2. The sub‐watershed BMP is located on the Resort site and located such that runoff from the project would be conveyed to the BMP prior to discharge from the Resort site. The runoff may be conveyed directly if the BMP is located downstream or redirected to the BMP through pipes or other conveyance. Each participating Project WQMP must demonstrate that it is within the tributary area to the sub‐watershed BMP. Projects not located upstream but using a sub‐ watershed BMP would proceed to Section 5 and proceed according to the alternative compliance plan.

3. The sub‐watershed BMP provides equal or greater overall benefit than would be achieved by LID BMPs within the footprint of each redevelopment project that participates in this sub‐ watershed BMP. By meeting conditions 1 and 2, an amount of water equivalent to the DCV is fully infiltrated in the BMP, therefore this requirement is met and nothing further needs to be demonstrated in this regard.

4. The sub‐watershed BMP is constructed and operational prior to occupancy of each project. This is met by maintaining a current version of the BMP Exchange Spreadsheet (see Section 5). Only completed and operational projects are to be shown in this spreadsheet, therefore only completed and operational projects are available to use for compliance.

5. The sub‐watershed BMP must be perpetually monitored and maintained for the life of the facility. The monitoring requirements (which include a combination of visual inspections, sampling, testing or other quantitative measures), operation recommendations and maintenance requirements are development and included as part of the sub‐watershed BMP WQMP (see Section 4.3) through the development of the O&M plan specific to each facility.

4.4.3 Documenting Participation in a SubWatershed BMP for SubWatershed BMP Compliance
Priority projects that are proposed to utilize sub‐watershed BMPs for regulatory compliance are required to determine the capacity that they will require in the sub‐watershed BMP (Section 4.3.4) and document that this capacity is available for utilization through using the BMP Exchange Spreadsheet (Section 5). An updated and current copy of the BMP Exchange Spreadsheet should be provided with the priority project’s Final Project WQMP. Additional details regarding the BMP Exchange Program are provided in Section 5.

4.4.4 Documenting Participation in a SubWatershed BMP as an Alternative Compliance Approach
Sub‐watershed BMPs may be utilized as part of alternative compliance. The requirements for utilizing a sub‐watershed BMP as alternative compliance, including documentation of capacity credits and debits and updating the BMP Exchange Spreadsheet, are presented in Section 5 of this Master WQMP.

Appendix 4-B
Fact Sheet No. 1: Underground Infiltration BMP Fact Sheet Underground infiltration is a vault or chamber with an open bottom that used to store runoff and percolate into the subsurface. A number of vendors offer proprietary infiltration products that allow for similar or enhanced rates of infiltration and subsurface storage while offering durable prefrabricated structures. There are many varieties of proprietary infiltration BMPs that can be used for roads and parking lots, parks and open spaces, or mixed-use and commercial uses at the Disneyland Resort.

Feasibility Screening Considerations
 Underground infiltration basins shall pass infeasible screening criteria to be considered for use (Worksheet INF, Appendix 3-B.2)
 Feasibility screening shall be supported by a site-specific geotechical investigation and measurement of infiltration rates.

Opportunity Criteria
 Soils are adequate for infiltration or can be amended to provide an adequate infiltration rate.  Appropriate for sites with limited surface space.
 Can be placed beneath roads, sidewalks, parking lots, parks, and some commercial areas.  Potential for groundwater contamination can be mitigated through isolation of pollutant sources, pretreatment of inflow, and/or demonstration of adequate treatment capacity of underlying soils.  Tributary area land uses include mixed-use and commercial, roads and parking lots, and parks and open spaces. High pollutant land uses should not be tributary to infiltration BMPs.

Disneyland-Specific Design Criteria and Considerations
□ Placement of BMPs should observe geotechnical recommendations with respect to geological hazards (e.g. landslides, liquefaction zones, erosion, etc.) and set-backs (e.g., foundations, utilities, roadways, etc.)
□ Diversion structure located up-gradient from infiltration BMP should divert water from the main Resort storm drain system for flows to be treated, while allowing higher flows to bypass the BMP.
□
Pre-treatment of the diverted water shall be provided upstream of the infiltration facility, with access for maintentace. Water bypassing pre-treatment should not be directed to the facility. At a minimum, a pre-treatment BMP certified by the Washington State Department of Ecology for “Pretreatment” shall be used (e.g., Contech CDS system) (http://www.ecy.wa.gov/programs/wq/stormwater/newtech/technologies.html).

Disneyland Resort Master WQMP Appendix 4‐B
December 2014 Page 2 of 2 Fact Sheet No. 1
□ The diversion structure and pre-treatment system shall be sized with adequate capacity to match the long term capture efficiency of the infiltration gallery. □
Underground infiltration should not be used for drainage areas with high sediment production potential unless preceded by a BMP that provides M or H level of treatment effectiveness for TSS. Preferrably, pre-treatmenbt systems for high sediment source areas should be certified by the Washington State Department of Ecology for “Basic Treatmet” (http://www.ecy.wa.gov/programs/wq/stormwater/newtech/technologies.html). □ Design infiltration rate should be determined as described in TGD Appendix VII. □ Underground structural storage features shall provide capacity for the design retention volume (pipes, chambers, vaults, modular systems, gravel reservoirs). □ A bedding layer below the storage layer is recommended for structural purposes and/or to provide a filtering layer for sediments.
□ Inspection ports or similar design features shall be provided to verify continued system performance and identify need for major maintenance.
□ Access ports, if feasible, should be provided to allow for periodic removal of sediment. □ For infiltration facilities beneath roads and parking areas, structural requirements should meet H-20 load requirements.

Computing Underground Infiltration Device Size
Underground infiltration BMPs vary by design and by proprietary designs. The sizing of the subwatershed infiltration BMP should follow the procedure described in Section 4.3.2 of this Master WQMP.  Volumetric computations shall be per the vendor specifications.  Infiltration rate and drawdown calcualtions shall be based on the design infiltration rate, with an appropriate factor of safety, per methods described in TGD Appendix VII and TGD Worksheet H.  Fact Sheet No. 2 in Appendix 4-B should be used to calculate the capture efficiency of the subwatershed BMP.  Fact Sheet No. 3 in Appendix 4-B should be used to calculate the required diversion flowrate for the diversion system and pre-treatment BMP.

DISNEYLAND RESORT SUB-WATERSHED BEST MANAGEMENT PLAN (BMP) WORK PLAN
Late in 2013, Regional Board staff were approached by representatives from the Disneyland Resort to discuss a sub-watershed BMP approach proposed by Disneyland Resort. The SubWatershed BMP Plan that would be developed by Disneyland Resort would involve managing storm water runoff from the development of new projects within the Resort by using subgrade LID infiltration BMPs within the Disneyland Resort area, but not necessarily underlying the new projects. In subsequent conversations with Mr. Keith Linker, the Principal Engineer for the City of Anaheim, the City asked that Regional Board staff make a determination as to whether the proposed Disneyland Resort Sub-Watershed BMP Plan would represent an acceptable on-site stormwater management approach as described in the Orange County Municipal Separate Storm Sewer System (MS4) Permit (Order No. RB-2009-0030).

Regional Board staff have reviewed the concepts for post-construction infiltration BMPs proposed in "Disneyland Resort, Sub-Watershed BMP Work Plan" dated December 12, 2013. Board staff's comments respond to the project-specific Sections 3-5 and Appendices A & B of the submitted document and do not address the statements or conclusions presented in Section 2, Technical Background.

For post-construction storm water management, Disneyland Resort is proposing the implementation of on-site LID retention facilities at the sub-watershed scale. To implement this approach, it is Board staff's understanding that:
• The proposed LID infiltration BMPs would be used in areas of the Disneyland Resort site where a sub-watershed scale LID infiltration BMP would result in retention of an equal or greater volume of runoff on-site in comparison to LID BMPs implemented only within each project footprint, including consideration for protecting subsurface infrastructure (utilities, corridors and/or tunnels) and building/feature foundations. The Sub-Watershed BMP Plan will be used to augment a project-specific site planning process by identifying feasible sites for on-site storm water infiltration at the sub-watershed scale; • The proposed infiltration BMPs would be functional prior to occupancy of the area of new development or significant redevelopment;

• Potential types of sub-watershed scale retrofit projects would include Site 2 (Walkway Expansion), Site 4 (Retail, Dining and Entertainment) and Site 5 (Lodging), as identified in the submitted document, however other similar sub-watershed scale retrofit projects that meet the applicable regulatory criteria could be identified as part of future planning activities and included as part of the Sub-Watershed BMP Plan;
• Maintenance schedules for the infiltration BMPs would be developed as specific plans for the implementation of BMPs are determined. At a minimum, the schedule should meet the requirements set forth in the current Model WQMP and must result in the continued proper operation of the units, but could be adapted with time and experience; and, • If excess treatment capacity results in a "BMP Credit", that capacity would only be used to offset treatment of runoff from areas with similar uses as those areas creating the credit.

Section XII.C.2 of the Orange County MS4 Permit requires priority development projects to retain the Design Capture Volume on-site to the extent feasible. Section XII.C.5 of the Orange County MS4 Permit states that in situations where constraints limit the implementation of LID BMPs, such as space restrictions, potential for impact of underground infrastructure in the immediate project vicinity, etc. inherent in some in-fill projects and redevelopment projects, LID principles could be integrated into a regional or sub-watershed management approach. The proposed approach for a Sub-Watershed BMP Plan would be consistent with both provisions.

Based on the submitted document, staff agrees that the conceptual approach presented in the December 12, 2013 sub-watershed BMP Work Plan for the Disneyland Resort meets the requirements of the current Orange County MS4 Permit and the County's current Model Water Quality Management Plan (WQMP). As allowed by the MS4 Permit, the Board defers to the City of Anaheim (City) for approval of the Resort's Sub-Watershed BMP Plan (and BMP retrofit projects to be identified therein) as the lead agency for post-construction BMP strategies and facilities within its jurisdiction. It is anticipated by Board staff that as additional details are established through the development and implementation of WQMPs for these projects, the City of Anaheim will provide the normal review, approval and inspection actions as needed to meet the requirements in the current and forthcoming Orange County MS4 Permits and the City of Anaheim Local Implementation Plans.

5 Alternative Compliance Plan

5.1 Purpose
Alternative compliance for LID BMP and treatment control BMP requirements may be needed in cases where site‐specific constraints do not allow for full implementation of the required LID BMPs and/or treatment control BMPs within the project footprint or in a sub‐watershed infiltration BMP downstream of the project. In this case, the project must document this infeasibility and utilize alternative compliance options for the remaining DCV that could not be retained, biotreated, or treated by the project. The Resort’s preferred method for alternative compliance is to participate in the Resort’s “BMP Exchange.”
This section describes the Resort’s BMP Exchange Program and provides guidelines for participating in the BMP Exchange to meet alternative compliance requirements. The BMP Exchange provides a platform for Resort‐wide water quality management, and maintains a record of approved sub‐ watershed BMPs located within the Resort and the projects that have recorded a debit or have used credits from the BMP Exchange. The BMP Exchange also establishes a system to track the surplus of treatment capacity available in other locations throughout the Resort and makes this surplus available as credits to projects that require alternative compliance. The tracking spreadsheet for the BMP Exchange is part of the Master BMP Project Tracking Sheet located in Appendix 5‐A.

The bullets below provide guidance for using this section to answer three common questions:
 Is my project eligible for participation in the BMP Exchange? Individual Project WQMPs should refer to the findings, procedures, and other guidance in Section 3 and Section 5.2.1 to demonstrate that the project is eligible to participate in the BMP Exchange.  How are credits generated for the BMP Exchange? Credits (expressed in square feet of development) are generated by implementing BMP retrofits and/or providing excess capacity in BMPs installed as part of other projects. Credits generated are documented for each project by completing the form found in Appendix 5‐B. See Sections 5.3.2, 5.3.3, and 5.3.4 for guidance on calculating the quantity of credits generated by different types of BMPs.  How are credits utilized from the BMP Exchange? Projects must first demonstrate that they are eligible to enter the BMP Exchange as discussed above. An eligible project may utilize existing credits by documenting the debit and identifying the land use category. The credit request from the BMP Exchange to offset the project’s debit is formalized by providing the completed form found in Appendix 5‐B. Environmental Affairs will then update the BMP Project Tracking Sheet (Appendix 5‐A) with each Project WQMP submittal. See Sections 5.2.3 and 5.3.6 for more guidance. Figure 3‐4 in Section 3 provides a graphical representation of the concepts presented below.

LaRoc Environmental 5‐2 December 2014 – Final

5.2 Alternative Compliance Process for Priority Projects This sub‐section presents a stepwise process for participation in alternative compliance. The steps are described in the following sub‐headings and are illustrated in Figure 5‐1.

5.2.1 Step 1: Demonstrate Eligibility to Enter Alternative Compliance (BMP Exchange) The project applicant must first demonstrate in the Preliminary Project WQMP that the project is eligible to participate in the BMP Exchange. This should be done by demonstrating that neither project‐based nor new sub‐watershed BMPs are feasible for the portion of the sizing obligation and that the project seeks to meet it with alternative compliance. Sections 3 and 4 of this Master WQMP contain the site assessment process and sizing requirements for project‐based and sub‐watershed LID BMPs, respectively. These sections also include feasibility criteria that should be used as a basis for demonstrating infeasibility and eligibility for participation in the BMP Exchange, where applicable. If a project still has remaining sizing obligations after attempting to use LID BMPs and treatment control BMPs, then the project is eligible to enter the BMP Exchange and request credits for the remaining volume as specified in the following sections. An explanation of eligibility must be provided in the Project WQMP, and should include one or more of the following factors, as applicable:
 Infiltration rate/geotechnical feasibility,
 Proximity to existing or proposed resort infrastructure (utility corridors, tunnels, building foundations, storm drain system, etc.),
 Impact on Resort activities and/or On‐Stage operations,  Impact on Resort guest experience and/or safety,
 Impact of operations and maintenance requirements,
 Space constraints, and/or
 Significantly greater water quality benefit through participation in the BMP Exchange.

Figure 5‐1 illustrates eligible pathways for entering alternative compliance and identifies the major steps required to participate in the BMP Exchange.

5.2.2 Step 2: Calculate Required Quantity and Type of BMP Exchange Credits Needed (Debits) for a Priority Project
BMP Exchange credits, expressed as a square footage of impervious surface1 , are the means by which
the Resort tracks BMP surplus capacity generated in Resort sub‐watershed BMPs. In addition, the BMP Exchange is used to track the debits for priority projects that cannot satisfy LID and treatment control BMP requirements and have secured credits from the BMP Exchange. The following steps are involved in calculating the quantity and type of BMP Exchange credits being requested by the project applicant.

For accounting purposes, a project requesting or needing credits from the BMP Exchange will calculate the development area in square feet not being treated by project BMPs as a debit for the project.

1. Calculate new or replaced impervious surface that requires treatment. BMP Exchange credits are represented by a “developable area” in units of square footage of impervious surface.

2. Adjust for reduced imperviousness, if needed. Nearly all projects within the Resort have a high degree of imperviousness; therefore a simple conservative method assumes that the number of BMP Exchange credits needed is equal to the total project area. If a project has a significant

fraction of pervious surface, this area can be removed from the BMP Exchange credit request if it is designed to be self‐retaining (i.e., to produce no runoff during the 0.85‐inch storm event).

This can reduce the number of credits needed. For example, if a project is 14,000 sq ft and includes 1,500 sq ft of landscape features that are enclosed within an elevated curb (i.e., that do not contribute runoff during the 0.85‐inch storm), then the total BMP Exchange credit needed (or the project’s debit) is 12,500 sq ft. All priority projects must still meet source control and site design requirements.

3. Account for partial LID/treatment control requirements already met by the project. If a project has been able to feasibly address a portion of the DCV via LID and/or treatment control BMPs, then the amount of BMP Exchange credit needed can be reduced by the fraction of the DCV already met by the project. For example, if a project has captured 40 percent of the DCV within the project, then the total required BMP Exchange credit needed or project debit can be reduced by 40 percent.

4. Determine types of credits needed based on proposed surface types and uses. There are two “surface type” groups within the Resort that are distinguished for the purpose of determining credit and debit types needed:
 Surface Type 1: Parking lots and similar areas with significant pollutant generating activities;
 Surface Type 2: All other impervious surfaces.

The project’s debit calculated in Steps 1, 2, and 3 should be subdivided based on the proportion of the untreated runoff originating from each of these surface type categories, and the debit in each category should be tracked separately. A template worksheet for documenting calculation of the project’s debit by category is provided in Appendix 5‐B.

5.2.3 Step 3: Document Participation in Alternative Compliance (BMP Exchange) As will be discussed in Section 5.3, participation in the BMP Exchange requires the tracking of BMP Exchange credits and debits, and reporting to the City. A current and updated copy of the Master WQMP Project Tracking Sheet should be attached as an appendix to each Project WQMP that involves generation or utilization of credits. Section 5.3 provides details on how participation in the BMP Exchange must be documented. All projects requesting to participate in the BMP Exchange must submit the Preliminary Project WQMP to Environmental Affairs to validate the availability of credit from the BMP Exchange and obtain an updated Master WQMP Project Tracking Sheet (Appendix 5‐A).

5.3 Resort BMP Exchange
This section describes the “rules of the road” for the Resort’s BMP Exchange. The BMP Exchange Program consists of three primary elements, described in detail in the following sections. These elements are:

Disneyland Resort Master WQMP
Section 5: Alternative Compliance Plan
LaRoc Environmental 5‐5 December 2014 – Final

1. Criteria for generating and calculating BMP credits (Section 5.3.1, 5.3.2, 5.3.3, 5.3.4),

2. Requirements for utilizing BMP credits (Section 5.3.5), and

3. Requirements for tracking and reporting the BMP Exchange (Section 5.3.6).

Environmental Affairs is responsible for managing the BMP Exchange Program and maintaining the official version of the Master WQMP Project Tracking Sheet.

5.3.1 Options for Generating BMP Exchange Credits
In order to offset debits generated by projects with constraints, the BMP Exchange must have credits in the appropriate surface type requested (or better) available to use. There are three options for generating surplus treatment capacity that may be utilized as BMP Exchange credit. These options are:
 New capacity generated in retrofit BMPs across the Resort that are not located in a priority project area (Section 5.3.2);
 Excess capacity in BMPs within other new and significant redevelopment projects that have been sized and designed to treat additional area beyond that required for the respective project for which they were constructed (Section 5.3.3); and
 Excess capacity in a sub‐watershed BMP to which the project is not tributary (Section 5.3.4).

The referenced sections above provide guidance for generating and calculating BMP credits for each of these options.

5.3.2 Generating Credits through BMP Retrofits
BMP retrofits of areas outside of a priority project footprint (i.e., those not requiring treatment) offer opportunities to generate a surplus of treatment capacity for the BMP Exchange. Retrofits for roofs and parking lots present the majority of the retrofit opportunities at the Resort. Retrofit projects can be implemented as standalone efforts, or associated with a priority or non‐priority project as long as a WQMP is completed. Priority projects with identified spatial or operational constraints can opt to consider retrofitting a comparable use area (roof, parking, etc.) at another location within the Disneyland Resort to generate BMP Exchange surplus capacity. Once the BMP retrofit is completed, the surplus capacity can be added to the BMP Exchange and used to assist with compliance for the constrained redevelopment project.

In general, BMP retrofit opportunities include, but are not limited to:

Roof Downspouts – Downspouts from building roofs that are directly connected to the storm drain system may benefit from retrofitting them to drain to existing pervious areas (infiltration trenches, proprietary infiltration devices, or bioretention units). These areas may also be candidates for Note:

If a project is tributary to a sub‐watershed BMP, then participation in that BMP is not considered alternative compliance and only Section 4 applies.

redesigned landscaping that incorporates rainwater harvesting with rain gardens. TGD Fact Sheets for Localized On‐Lot Infiltration (HSC‐1), Impervious Area Dispersion (HSC‐2), or Rain Barrels (HSC‐4) may be consulted for design guidance.

Walkways, Staging Areas, Parking, and Other Impervious Areas – Applies by converting impervious areas, such as backstage areas and parking lots, by retrofitting them with pervious materials like porous concrete or asphalt, or permeable pavers, either independently of other projects or as part of redeveloped or remodeled areas, if practical. Remodeling does not require LID or treatment control BMPs to be incorporated and may offer additional opportunities for retrofit BMPs to augment the BMP Exchange by generating surplus capacity. TGD Fact Sheet for Permeable Pavement (INF‐6) may be consulted for design guidance.

Catch Basins – The Disneyland Resort may retrofit catch basins with media filters. The media and configuration options available for these proprietary devices allow for strategic implementation to address pollutants of concern specific to a site and can generate BMP surplus or offsets. It should be noted that simple catch basin inserts (non‐media filtration type) do not address pollutants of concern for the Resort and are not capable of generating BMP credits. TGD Fact Sheets for Catch Basin Planter Boxes (BIO‐7) or Cartridge Media Filters (TRT‐2) may be consulted for design guidance.

Landscape Retrofit and Re‐design (including infiltration design and/or efficient irrigation) – Landscaping currently in large raised and curved planter areas may be retrofitted with curb cuts and/or re‐designed and re‐graded to provide opportunities for infiltration and treatment. Areas that can be retrofitted to provide equivalent treatment characteristics of vegetated swales, vegetated buffer strips, bioretention systems, infiltration trenches, or pervious areas may be able to provide BMP surplus or offset for other new or re‐development areas. TGD Fact Sheet for Localized On‐Lot Infiltration (HSC‐1), Street Trees (HSC‐3), Infiltration Trench (INF‐2), Bioretention with no underdrain (INF‐3), Bioinfiltration (INF‐4), Bioretention with underdrains (BIO‐1), Vegetated Swale (BIO‐2), Vegetated Filter Strip (BIO‐3), Planting/Storage Media (MISC‐1), or Amended Soils (MISC‐2) may be consulted for design guidance.

Submittal Requirements for BMP Retrofits
BMP retrofits may be implemented as part of a priority project, a non‐priority project, or as a standalone effort. If the retrofit is associated with a priority project, the BMP design and location should be documented as part of the Project WQMP, clearly indicating that the BMP is intended as a voluntary retrofit measure to generate excess capacity within the Resort, not as part of compliance for the priority project. If the retrofit is proposed as a standalone effort and is not associated with a priority project, then an abbreviated Project WQMP should be compiled to present the BMP design details and specifications and the resulting equivalent BMP Exchange credits provided by the retrofit BMP.

Calculating Credits Generated by BMP Retrofits
The credits generated by retrofit LID BMPs can be calculated based on how large of an area it addresses.

For this option, it is assumed that the BMP is sized for the entire DCV for the area it addresses. The tributary area must be subdivided into the two surface types of credits described in Section 5.3.5. If the Disneyland Resort Master WQMP
Section 5: Alternative Compliance Plan
LaRoc Environmental 5‐7 December 2014 – Final
BMP is undersized relative to its tributary area, the methods used for sub‐watershed BMPs should be followed (Section 4.3.4) to estimate the credits generated.

5.3.3 Generating Credits through Treatment of Additional Area by Priority Project BMPs Priority projects at the Resort may design their project‐based LID and treatment control BMPs to accept runoff from a larger tributary area beyond the project footprint. The additional area treated can be claimed as credit for the BMP Exchange.

Submittal Requirements for Surplus Treatment by Priority Project BMPs Priority projects are required to submit Preliminary and Final Project WQMPs, which will detail the design criteria and specifications for the LID and treatment control BMPs associated with the project.

Additional tributary area and associated capacity beyond that required to satisfy the regulatory criteria for the priority project itself should be clearly identified in the Project WQMP as being a voluntary treatment area. This additional area can be entered into the BMP Exchange once the BMP is operational (Section 5.3.6 and 5.3.7).

Calculating Credits for Surplus Treatment by Priority Project BMPs The amount of credit generated is equal to the amount of additional voluntary area treated in the project BMPs. The BMPs must be designed for the full DCV sizing criteria for all of the areas that they treat. The surplus tributary area must be subdivided into the two surface types of credits described in Section 5.3.5.

5.3.4 Generating Credits through Surplus Capacity in SubWatershed BMPs Sub‐watershed BMPs may also generate credits to be used in alternative compliance for projects that are not located within the tributary area of the sub‐watershed BMP as shown in Figure 5‐2. A sub‐ watershed BMP may be installed as a stand‐alone project or in conjunction with one or more priority projects to both offset debits from those projects and generate surplus credits. The sub‐watershed BMP credits may be used to offset debits from one or more priority projects located outside the sub‐ watershed BMP’s tributary area. Section 4.3.4 presents how to evaluate credits available in a sub‐ watershed BMP that will be tracked using the BMP Exchange (Section 5.3.6 and 5.3.7) and utilized by priority projects according to Section 5.3.5.

5.3.5 Utilization of BMP Exchange Credits
Participation in the BMP Exchange requires the tracking of BMP Exchange credits and debits, and reporting to the City. The Resort’s Master WQMP Project Tracking Sheet serves as the primary basis for demonstrating that BMP Exchange credits are available for the project with a debit due to constraints or other factors and that credits are used appropriately. Appendix 5‐A includes the Master WQMP Project Tracking Sheet for the Resort.

Utilization of Credits Across Similar or Lower Pollutant Generating Land Uses As embodied in the Master WQMP Project Tracking Sheet, BMP Exchange credits can be generated, tracked, and utilized in two categories of surface types based on the pollutants that they would be expected to generate. These categories are:

Disneyland Resort Master WQMP
Section 5: Alternative Compliance Plan
LaRoc Environmental 5‐8 December 2014 – Final
 Surface Type 1: Parking lots and similar areas with significant pollutant generating activities.

These areas typically generate a greater number and quantity of potential pollutant types, including metals, oils and greases, and trash/debris.
 Surface Type 2: All other impervious areas.

In utilizing credits, a simple rule must be followed: it is acceptable to utilize credits toward projects with an equivalent or lesser pollution generating type; however the inverse is not acceptable. For example, credit generated by treating a parking lot (Surface Type 1) can be used to offset treatment debits for walkways or roof tops (Surface Types 2), however, a credit generated by treating a rooftop (Surface Type 2) cannot be used to offset treatment debits for a parking lot (Surface Type 1). This concept of exchanging “down” ensures that the overall pollutant impact in storm water runoff to the environment from this exchange exercise is anticipated to be a net benefit or neutral. The Master WQMP Project Tracking Sheet provides the ability to track each of these surface types.

Utilization of Credits Across Sub‐watersheds
Furthermore, credits can be utilized across sub‐watersheds within the Resort by following the principles laid out in this Master WQMP. The Master WQMP Project Tracking Sheet (Appendix 5‐A) is designed to account for all BMP credits and debits across the Resort to ensure they are applied and accounted for appropriately. As shown in Figure 5‐2, a new project site (light green) with constraints is planned in an existing drainage area (in orange) connected via a storm drain to the City’s storm drain system. An already built project is located in the adjacent drainage area (in light blue) that is tributary to a sub‐ watershed BMP (dark blue) that has generated credits that have been noted in the Master WQMP Project Tracking Sheet. The BMP Exchange has available credits to offset the light green project site that cannot accommodate LID or treatment BMPs.

5.3.6 BMP Exchange Tracking Methodology
Any project site using the BMP Exchange, either generating or utilizing credits, shall document the credit or debit in the form in Appendix 5‐B and submit it for approval by Environmental Affairs. Environmental Affairs will review the forms, verify the entries, and update the Master WQMP Project Tracking Sheet.

Environmental Affairs will provide the project’s proponent with an updated Master WQMP Project Tracking Sheet to include with the project’s WQMP for submittal to the City for review and approval. As new projects generating credits or requesting offset of debits are submitted and approved by the City, Environmental Affairs will update and manage the surplus available in the BMP Exchange through the Master WQMP Project Tracking Sheet as part of maintaining the Master WQMP to keep it current and viable for the Resort. A running total of credits and debits will be documented in the Master WQMP Project Tracking Sheet (Appendix 5‐A) for submission to the City whenever credits are generated or used. Additionally, BMP locations should be added to Exhibit 5‐A.

Appendix 5-B.2: Credit Generation - BMP Exchange Calculations Step 1: Determine Type of Alternative Compliance BMP Generating Credits 1 If a retrofit or new BMP is not located in a priority development project area and is proposed to generate
BMP credits (Section 5.3.2) then…
Go to Step 2.
2 If a BMP is designed to treat additional area beyond that required for the project and BMP credits are generated
(Section 5.3.3) then…
Go to Step 3.
3 If BMP credits are generated by a sub-watershed BMPs
(Section 5.3.4) then…. Go to Step 4.

Step 2: Simple Retrofit BMP Credits Created by Full Sized Retrofit BMPs

2.1 Determine the area tributary to the retrofit BMP, Atrib Atrib= sq-ft

2.2 Is BMP sized for DCV required to meet LID requirements for the entire tributary area?
Use Resort Sizing Factor Approach, Simple DCV
approach, or 80% capture method (Section 3.7)
Circle one: Yes
No
DCV= cu-ft

2.3 If no, then upsize the BMP, reduce the tributary area to meet full DCV sizing, or calculate credits following Step 4, below

2.4 If yes, the credits created by the retrofit BMP are equivalent to the tributary area (Atrib), ACredit
ACredit= sq-ft

2.5 Determine the types of credits created based on tributary land uses of impervious area:

Note: ACredit1 + ACredit2 shall equal ACredit
1) Surface Type 1:

Parking lots, roadways, and similar activities with
significant traffic and/or other significant pollutant
generating activities.

ACredit1 = sq-ft
2) Surface Type 2:

Other surface types.

ACredit2 = sq-ft
Step 3: Additional Tributary Area Treated in Full Sized Priority Project BMPs

3.1 Determine the new or replaced impervious area tributary to the Priority Project BMP that requires treatment, Atrib_req Note: tributary area shall include run-on areas to be treated by the proposed BMP
Atrib_req sq-ft

3.2 Determine the excess impervious area tributary to the Priority Project BMP that requires treatment, Atrib excess Atrib_excess sq-ft

3.3 Determine the total area tributary to the Priority Project BMP, Atrib where Atrib = Atrib_req + Atrib_excess
Note: Include new and replaced impervious area and as
noted above, run-on from other areas not already treated Atrib= sq-ft

3.4 Is BMP sized for DCV required to meet LID requirements for the entire tributary area (Atrib)?
Use Resort Sizing Factor Approach, Simple DCV
approach, or 80% capture method (Section 3.7)
Circle one: Yes
No

3.5 DCV= cu-ft

3.6 If no, then upsize the BMP, reduce the tributary area to meet full DCV sizing, or calculate credits following Step 4, below

3.7 If yes, then BMP Exchange Credit is equal to the excess area treated (Acredit = ATrib excess) ACredit= sq-ft

3.8 Determine the types of credits created based on tributary land uses of impervious area:

Note: ACredit1 + ACredit2 shall equal ACredit
1) Surface Type 1:

Parking lots, roadways, and similar activities with
significant traffic and/or other significant pollutant
generating activities.

ACredit1 = sq-ft
2) Surface Type 2:

Other surface types.

ACredit2 = sq-ft
Step 4: Surplus Capacity in Sub-Watershed BMPs and Undersized Retrofit BMPs

4.1 Determine the area tributary to the sub-watershed BMP, Atrib
Atrib= sq-ft

4.2 Use Appendix 4-C.2 to determine the capture efficiency of the sub-watershed BMP, %Cap %Cap= %

4.3 Calculate the total credits created by the sub-watershed BMP using the following equation:

ACredit = Atrib × (%Cap)/80%
Acredit= sq-ft

4.4 Determine the types of credits created based on tributary land uses of impervious area:

Note: ACredit1 + ACredit2 shall equal ACredit
1) Surface Type 1:

Parking lots, roadways, and similar activities with
significant traffic and/or other significant pollutant
generating activities.

ACredit1 = sq-ft
2) Surface Type 2:

Other surface types.

ACredit2 = sq-ft

PURPOSE
The City of Anaheim (City) retained the service of Ardurra to perform a hydraulic analysis for the proposed Disneyland Forward Project within the Disneyland Resort Area (DRA) to identify any water system improvements needed to accommodate ultimate growth of DRA.

DISCUSSION
The water hydraulic scenarios were analyzed under Peak Hour Demand (PHD) condition and Maximum Day Demand plus Fire Flow (MDD + FF) condition:
• Scenario 1: Currently entitled land use in DRA
• Scenario 2: Modified land use as part of the Disneyland Forward Project The hydraulic analysis was performed using the City’s future (2040) system model developed as part of the 2020 Water Master Plan (WMP). Psomas, the Developer’s consultant, provided demand allocation information for Scenario 1 and Scenario 2 and was included as Attachment A. The provided demand information was used to update the demand allocation within the DRA in the model. In addition, the City developed its 2020 Urban Water Management Plan (UWMP) post completion of the 2020 WMP which includes updated future water demand forecasts. The 2040 demand set in the model was updated so that the total demand of DRA and the remaining areas is consistent with the 2040 systemwide demand projected in the 2020 UWMP.

The 2040 system was analyzed under MDD extended period simulation (EPS), and was evaluated at peak hour demand (Hour 5). The 12-inch main that bisects Disneyland between Disneyland and California Adventure Park between Disneyland Dr and Harbor Blvd is assumed to be abandoned.1 Model results were checked against City’s Design Guidelines, as summarized in Table 1.
