Chapter 1 INTRODUCTION
1.1 Background
The Del Mar Fairgrounds is one of the preeminent community event and activity centers in San Diego County and a major visitor serving facility of regional, if not state-wide significance. Over 3-million people annually attend events occurring within the Del Mar Fairgrounds. Since it's opening in 1937, the Del Mar Fairgrounds coastal location, within full view of the Pacific Ocean, has been a major component of its success. At the same time, success brings traffic and growth pressures that, if left unchecked and unplanned, have the potential to impact coastal resources.
This Consent Order Compliance and Physical Development Plan ("Plan") was prepared in response to California Coastal Commission ("CCC") Consent Cease and Desist Order No. CCC-I2-CD-02 and Restoration Order No. CCC-I2-CD-RO-02 (herein the "Consent Orders"). The Consent Orders detail a variety of actions to be undertaken by the 22"d District Agricultural Association ("22"d DAA") inci ding submittal of a coastal development permit ("CDP") application for permanent authorization of typical short-term events to be held within the Fairgrounds, with measures to avoid and minimize impacts to habitat, and to accommodate and mitigate for associated traffic and parking impacts (hereinafter "Comprehensive CDP"). This Plan, which includes a full description of the typical short-term temporary events to be conducted within the Del Mar Fairgrounds along with mitigation measures to reduce associated impacts, is part of the Comprehensive CDP application required by the Consent Orders.1 1.1.1 Consent Orders
Section 3.3 B. of the Consent Orders states:
Within twelve (12) months of the effective date of these Consent Orders, DAA shall submit, and allow to be processed to Commission hearing under its normal procedures, a complete coastal development permit application for permanent authorization of typical short-term events to be held within the Fairgrounds that DAA wishes to retain or continue to perform and for which CCC staff has determined,
1 Habitat restoration, maintenance, and monitoring plans for the South Overflow Lot( "SOL"), Buffer Sites and Rip- Rapsites as required by the Consent Orders were submitted to the Coastal Commission on September 6, 2012. The restoration plans are subject to approval by the state Coastal Commission Executive Director and are not a part of this plan. n~~('A' C Del Mar Fairgrounds Consent Order Compliance March 2013 ~ ~ ~~ ~ r J and Physical Improvements Plan Page 1 CHAPTER 1 INTRODUCTION
after consultation with DAA, a permit to be necessary. This comprehensive permitting requirement excludes the Fair and Races as defined in Section 3.2.A.3 of these Consent Orders.
The Consent Orders further state, in Section 3.3.6.2:
In addition to all information and requirements of the Commission's permit application form, DAA shall include the following documents and information as part of the permit application:
a. A description of the typical short-term events to be conducted including the timing and duration of each; b. A scaled map of the Fairgrounds depicting the location of the events described in 3.3.8.2.a within the Fairgrounds including, but not limited to an analysis of measures to avoid sensitive habitat areas and to minimize impacts to species that use such habitat; and c. A description of the measures to accommodate and mitigate for the increased parking and traffic demands resultantfrom the temporary events described in 3.3.8.2.a.
For consistency, this Plan uses the term "temporary events" to refer to both "short-term events" and "temporary events" wherever those terms are used in the Consent Orders. This Plan, which includes a full description of the typical temporary events to be conducted within the Del Mar Fairgrounds, is submitted to the Coastal Commission as part of the Comprehensive CDP application described in Section 3.3.6 of Consent Orders.
Chapter 3 (Off-Season Temporary Events) and Chapter 4 (Second Race Meet) specifically address temporary events. The analysis of measures to avoid sensitive habitat areas and minimize impacts to species that use such habitat is provided in the Coastal Resource Summary Report( "CRSR") document submitted to the CCC with this Plan. Measures to accommodate and mitigate for parking and traffic demands are also provided in the CRSR (Public Access), along with an analysis of potential impacts to water quality, visual resources and visitor serving facilities.
Chapter 5 (Planned Physical Improvements) describes new facilities planned for the Fairgrounds, many of which will either accommodate or support temporary events. This portion of the Plan goes beyond what is required in the Consent Orders but is intended to ensure that future development within the Fairgrounds will be guided by site development standards that are protective of coastal resources. 1.1.2 Purpose of Plan
The Plan is intended to:
1. Fulfill specific requirements of the Consent Orders regarding the permitting of temporary events, to be held within the Fairgrounds;
2. Describe new physical improvements planned for the Del Mar Fairgrounds; and
3. Provide appropriate design criteria and mitigations for the activities and improvements described in the Plan to ensure that off-season temporary events and planned physical improvements would not have a significant adverse impact on coastal resources
^~~('~ C Del Mar Fairgrounds Consent Order Compliance March 2013 ~ ~ ~~ J and Physical Improvements Plan Page 2 CHAPTER 1 INTRODUCTION 1.2 Location and Regional Setting
The Fairgrounds( "Plan area") is approximately 340 acres and is located in the cities of Del Mar and San Diego in northern San Diego County (see Figure 1-1 Vicinity Map). The Plan area is surrounded by open water bodies, preserved open space, roadways, a railroad line, and urban land uses.
Via de la Valle defines the northerly boundary, while the Interstate 5 (1-5) freeway defines the easterly boundary. Jimmy Durante Boulevard and the San Dieguito River floodplain define the southerly boundary. Rail tracks and Stevens Creek define the westerly boundary of the Fairgrounds.
Jimmy Durante Boulevard runs through the Plan area, and separates the main Fairgrounds area from the overflow parking areas and commercial recreation area to the east and south. These areas include: the South Overflow Lot ("SOL")/Phase I and II Salt Marsh Restoration areas south of Jimmy Durante Boulevard, the East Overflow Lot ("EOL") east of Jimmy Durante Boulevard, and the SurF &Turf recreational facilities between the EOL and I-5. The Surf &Turf Golf Driving Range( "GDR"j also serves as an overflow parking lot. 1.2.1 Surrounding Uses
The Fairgrounds boundaries and surrounding uses are depicted in Figure 1-2 (Surrounding Uses). Uses immediately surrounding the Fairgrounds include the following:
1. To the north is the Del Mar Hilton Hotel and other freeway oriented commercial uses located at the southeast corner of Via de la Valle and Jimmy Durante Boulevard, commercial and visitor serving uses along the north side of Via de la Valle from Jimmy Durante Boulevard west to Del Mar Downs Road, multi-family residential from Del Mar Downs Road further west to the railroad tracks; and a row of townhomes and a restaurant overlooking the Fairgrounds on the south side of Via de la Valle just east of Camino del Mar(Highway 101);
2. To the west is the railroad right-of-way. The railroad itself is elevated above the western side of Fairgrounds by a high berm on the northern half and a trestle on the southern half. The San Dieguito River passes underneath the trestle. Further west, beyond the berm and trestle is the mouth of San Dieguito Lagoon. Camino del Mar crosses the San Dieguito River approximately mid-way between the railroad tracks and the shoreline. Public beach areas in the City of Del Mar are located to the west of Camino Del Mar. The beaches are accessible from Camino Del Mar and residential streets to the south in the City of Del Mar. To the southwest across the San Dieguito River channel are two large multi-family residential developments flanked by single- family homes to the south and west along the ocean shoreline.
3. To the south is the San Dieguito River, beyond which lies the City of Del Mar Public Works Department yard and a mix of office/industrial uses and the San Dieguito River Park.
4. To the east is the I-5 freeway which is elevated above the project site. Further east beyond the freeway are large expanses of the San Dieguito River Park. A community serving shopping center is located east of I-5 on the south side of Via de la Valle.

The strong edge conditions formed by I-5, the San Dieguito River channel, the railroad tracks (including trestle and berm), and grade separation from Via de la Valle, create a well defined buffer from surrounding uses.
1.3 Regulatory Framework 1.3.1 Land Use Planning
City of Del Mar
The majority of the Fairgrounds is located within the City of Del Mar, as depicted in Figure 1-3 (Jurisdictional Boundaries). The Fairgrounds are designated as "Fairgrounds Racetrack"( "FR")in the Del Mar General Plan and zoned FR under the City's zoning code. The FR Zone provides that all allowable and accessory uses for the Del Mar Fairgrounds shall be regulated by the 22nd DAA. Avery small portion of the Fairgrounds located in the northwest corner is zoned Low Density Residential (LR). The LR zoned area lies on a steep hillside and will not be residentially developed.. The SOL, located south of Jimmy Durante Boulevard, is designated "Floodway" in the Del Mar General Plan and is zoned Floodway (FW).
City of San Diego
The areas of the Fairgrounds located east of Jimmy Durante Boulevard are within the City of San Diego. The EOL and GDR are designated as "Open Space" in the Torrey Pines Community Plan and zoned Open Space Park (OP-1-1) under the City's Land Development Code. The area north and east of the EOL, which includes the Surf &Turf recreational facilities is designated "Commercial Recreation" in the Torrey Pines Community Plan and zoned Agriculture Residential (AR-1-1) under the City's Land Development Code.
State Authority/Jurisdiction
Because the 22"d DAA is a state agency with an appointed board and independent authority to approve development within its jurisdiction, discretionary approvals and building permits for the Fairgrounds are not issued by local agencies. However, coastal permits for "development" as defined in Coastal Act Section 30106 are required by the CCC.
San Dieguito JPA
The Fairgrounds is located within the San Dieguito Joint Powers Authority ("JPA") River Park Focused Planning Area (FPA). The FPA extends along a 55 mile corridor that begins at the desert just east of Volcan Mountain and extends to the mouth of the San Dieguito River in Del Mar, thereby including the Fairgrounds project site. The goal of the River Park is to preserve open space and the natural floodplain, conserve sensitive resources, protect water resources, retain agricultural uses, and create educational and recreational opportunities. The 22"d DAA has worked with the JPA to achieve many of its planning goals.

n~~('A' C Del Mar Fairgrounds Consent Order Compliance March 2013 ~ ~ ~~ ~ ~~ `"~ and Physical Improvements Plan Page 10 CHAPTER 1 INTRODUCTION 1.3.2 Local Coastal Planning
The Del Mar Fairgrounds is built on filled tidelands and is therefore within the CCC's area of original jurisdiction. In such areas, Chapter 3 of the Coastal Act remains the standard of review and the CCC retains permit authority even where a Local Coastal Program has been certified. Both the City of San Diego and City of Del Mar have certified local coastal programs. The City of Del Mar's LCP land use plan and implementing ordinances specify that the Del Mar Fairgrounds is a "deferred certification area." The City of San Diego's LCP includes open space and agricultural land use designations for the areas east of Jimmy Durante Boulevard. However, all uses within the state-owned Del Mar Fairgrounds are not subject to local zoning and building regulations and permanently remain in an original jurisdiction area with respect to coastal permitting.
While the Coastal Act does not provide for LCP preparation within the area controlled by 22~d DAA, it is anticipated that this Plan will, as part of the approved Comprehensive CDP,_become a standard of review for future development within the Del Mar Fairgrounds in addition to Chapter 3 of the Coastal { Act. ~i 1.3.3 Regulation of Temporary Events
Generally, Coastal Development Permits for temporary events located in original jurisdiction areas or where an LCP has not been certified, are required only where certain conditions are present. As set forth in the Coastal Commission's Guidelines for Temporary Events (adopted 5-12-93), a Coastal Development would be required for a temporary event only where the proposed event would: ~, 1. [Be] held between Memorial Day weekend and Labor Day; and,
2. Occupy all or a portion of a sandy beach area; and
3. Involve a charge for general public admission or seating where no fee is currently charged for use of the same area (not including booth or entry fees).
The Guidelines also state that a coastal development permit may be required in any circumstance where it has been determined by the Executive Director or Commission that "unique or changing circumstances exist relative to a particular temporary event that have the potential for significant adverse impacts on coastal resources."
It is the intent of this plan to provide all necessary measures to ensure that temporary events do not have the potential for significant adverse impacts on coastal resources. 1.3.4 Documents Used in Plan Preparation
The plan relies in part on information in the following documents and some of the recommendations from these documents have been incorporated into the Plan. Documents previously submitted to the CCC in compliance with the Consent Orders: ,, ■EOL-GDR Site Plan Temporary Events and Uses Figure 3A as approved under CDP 6-12-067, '~ ~" ~ii~; submitted on September 6, 2012

Chapter2 FAIRGROUND OPERATIONS
2.1 Existing Fairground Operations
The year-round use of the Del Mar Fairgrounds is defined by three major operations: the San Diego County Fair, the Del Mar Thoroughbred Races, and off-season temporary events. As clarified in Chapter ~, 1, the off-season temporary„_events described in the Plan are the same as the short-term events referenced in the Consent Orders. Each operation is conducted during a discrete period of time without significant overlap. Throughout this plan the three operations are referred to simply as the Fair, the Races and Off-Season Temporary Events. F r- k 2.1.1 The Fair ~ ~ ~.~1~~.~,~:~L:~ ~~~ . `~~ ~,~ ~~~f r
The San Diego County Fair at Del Mar is one of the most successful and well-attended fairs in the United States, with an attendance of over 1.5 million visitors during it 24~day run. It is the fourth-largest fair in ~.. the U.S. and the largest fair in the California State Fair system. The annual Fair contributes in excess of $160 million to the local economy. The Fair season generally runs from early June to July 4th.
The Consent Orders acknowledge the ongoing activities of the Fair and exclude_. such activities from_ any . requirement to obtain CDPs. Proposed physical facilities which may support Fair activities, as well as off- seasontemporary events are included in this Plan. ~;,( 2.1.2 The Races ~ ~ ~~ ~~~~~ ~ ~`~-~ ~~” ~~
The Races are one of the leading horseracing meets in the country. The Races attract over 700,000 spectators over the 43?day season, which runs from mid-July to early September each year. Many more patrons watch and wager on Del Mar races from around California, the U.S. and the world through an extensive simulcast wagering network. An off-track betting facility operates on the Fairgrounds on a year-round basis to offer the public an opportunity to wager on racing events occurring at horseracing tracks around the U.S. The economic impact of the Races on the San Diego economy has been estimated to be in excess of $100 million.
The Consent Orders acknowledge the Races as an ongoing activity of the Fairgrounds and excludes such activities from any requirement to obtain CDPs. Proposed physical facilities which may support Race activities are included in this Plan.
n~~(I~ C Del Mar Fairgrounds Consent Order Compliance March 2013 ~ ~ ~~ "~ and Physical Improvements Plan Page 1 1 CHAPTER 2 FAIRGROUND OPERATIONS 2.1.3 The Off-Season
The third core operation of the Del Mar Fairgrounds is the off-season temporary events that start at the end of the Race season in September and continue until the first week of June, prior to the Fair season. During the off-season, the Fairgrounds can be very busy with up to 300 events and from 500,000 to 800,000 visitors. The off-season temporary events utilize almost all of the facilities on the Fairgrounds, particularly the exhibit buildings and the outdoor space around those buildings. The economic impact of the off-season events to the San Diego economy is estimated to be approximately $100 million.
As discussed in Section 1.1.1 above the Consent Orders require a detailed description of the off-season temporary events and measures to minimize or avoid impacts to identified coastal resources. This description is provided in Chapter 3 (Off-Season Temporary Events). Proposed physical facilities which may support off-season temporary event activities are identified in Chapter 5 of this plan.
2.2 Existing Fairground Infrastructure 2.2.1 Access and Internal Circulation
Primary public access to the Del Mar Fairgrounds is from the-'main parking lot bordering Jimmy Durante Boulevard. The main parking lot is accessible from two principal`access points and two secondary access points. The principal access points consist of the Main Gate entrance at the curve in Jimmy Durante Boulevard and the Crosby Gate entrance adjacent to the Surfside Race Place. Secondary access points consist of a driveway located at the southwest corner of the main parking lot and a driveway located approximately half-way between the southwest corner access and the Main Gate entrance. During the Fair, Races, and off-season the main parking lot can be reconfigured as needed to optimize access, egress, and circulation through the main parking lot, both for the public and service vehicles. A tunnel under Jimmy Durante drive connects the main parking lot to the EOL.
The Solana Gate provides an important secondary entrance to the Fairgrounds from Via de la Valle. This entrance is used as a service entrance to support activities taking place in the Fairgrounds and, as needed, for public access to parking areas on the west side of the Fairgrounds. Other service entrances to the Fairgrounds are located on Jimmy Durante Boulevard at the southwest corner of the Fairgrounds near the Del Mar Fire Station (Fire Gate) and at the northeast corner of the Fairgrounds approximately 200 feet south of Via de la Valle (Stable Gate).
Internal circulation within the Del Mar Fairgrounds consists of several interconnected service roads which link parking areas and provide access to all Fairground facilities. The paved road from the Solana Gate entrance provides access to the training track, racetrack (west end), green lot, west lot, then turns eastward to connect with Avenida de Las Palmas, the central roadway which fronts the Grandstand Complex on the north and exhibit halls on the south. On the east side, Avenida de Las Palmas connects to the main parking lot.
An unpaved perimeter roadway on the west and south side of the Fairgrounds extends from the paved Solana Gate roadway to the Fire Station on Jimmy Durante Boulevard providing access to the RV spaces n~~('~ S Del Mar Fairgrounds Consent Order Compliance March 2013 ~ ~ ~~ and Physical Improvements Plan Page 12 CHAPTER 2 FAIRGROUND OPERATIONS and maintenance areas adjacent the San Dieguito River. This road is a key emergency fire access road and is a heavily utilized bus route. A locked gate (Fire Gate) at the Jimmy Durante driveway limits access from the east side. A second, mostly unpaved, perimeter roadway extends from the Solana Gate roadway near the guard station, around the north side of the stables to connect with the stables entrance on Jimmy Durante Boulevard. This roadway provides access to the stables area.
In addition to the defined service roads, the entire Fairgrounds is highly accessible to service vehicles which can maneuver freely through both paved and unpaved passage ways between buildings in the exhibit and maintenance areas, on the racetrack and infield areas, and throughout the stables area and training track. The internal circulation roadways and off-roadway passages play a critical role in the set- up, take down and other logistical support associated with Fairground operations. 2.2.2 Parking
The Del Mar Fairgrounds contains a variety of parking areas that are utilized in different configurations depending on the season and type of event. A parking assessment report prepared by Linscott, Law & Greenspan (LLG), 3-12-12, in compliance with the Consent Orders, identifies twelve parking lots_. that are currently available to handle the needs of the public, employees, and others associated with Fairgrounds activities such as vendors, exhibitors, entertainers, and stable residents. The locations and general availability of these parking areas is shown in Table 2-1 and in Figure 2-1 (Existing Fairgrounds Parking).
Peak parking demand periods occur primarily during the Fair and Race seasons. The adequacy of parking for Fair and Race events is detailed in the Del Mar Fairgrounds Parking Assessment report. That report assesses the impacts of ceasing parking operations on the South Overflow Lot (SOL) to make way for its restoration as a salt marsh wetland as required by the Consent Orders. The report recommends three potential improvements, any one of which would individually negate the loss of the SOL parking: 1) Additional Off-Site Parking, 2) A Seasonal Rail Platform, and 3) On-Site Parking Lot Modifications. None of these potential improvements are anticipated to be necessary to ensure adequate parking for temporary events during the off-season. However, on-site parking lot modifications to increase parking capacity could potentially reduce utilization of the overflow lots.
This Plan addresses the availability and management of parking during the off-season. While parking demand during the off-season is significantly lower than the Fair and Races, the limited supply of paved parking poses a potential temporary constraint to parking operations during rainy months. Such an occurrence would be most likely when the current paved parking areas are being utilized for outdoor events such as RV and cars shows. Planned physical improvements to pave the EOL (Section 5.2.7, Semi- Permeable Paving of EOL) and/or build a parking structure (Section 5.2.8, Parking Structured would remove this constraint.
The parking totals in the Table 2-1 represent existing parking available prior to the closure of the SOL and construction of the proposed new exhibit hall (described in Chapter 5). Use of the SOL has already been discontinued for off-season parking. Under current conditions a total of 10,550 parking spaces will be available for use during the off-season.

The new exhibit hall will alter the parking configuration in the valet parking area and a portion of the Carnival Area. However, 1,156 new subterranean parking spaces and valet parking in the new exhibit hall will result in a net increase in parking. 2.2.3 Stormwater
The Del Mar Fairgrounds is located within the San Dieguito River Watershed, which drains approximately 346 square miles in central San Diego County. The majority of the watershed is located upstream of Lake Hodges (the dam at the lake only supplies flows to the lower San Dieguito River during large storm events). The San Dieguito River, the watershed's primary drainage course (including San Dieguito Lagoon), is located along the southern boundary of the Fairgrounds. Stevens Creek, a tributary of the San Dieguito Lagoon, is located along the western and northern boundaries of the Fairgrounds. Nearly the entire Fairgrounds site is located in an area subject to flooding during a 100-year storm event.
Presently, there are 16 separate drainage basins within the Del Mar Fairgrounds site. An existing storm drainage system conveys runoff from the various drainage basins to four discharge points along the San Dieguito River and three discharge points along Stevens Creek. With the construction of the exhibit halls and front/gate administrative building some of the drainage basins will be consolidated, split and/or reconfigured and new or upgraded drainage lines will be added. However, no new discharge points will be required for any development proposed in this Plan. In several existing drainage basins, low-flow runoff is currently directed to ponds on-site where it either evaporates or percolates into the ground. Under high-flow conditions, water is conveyed either by surface flow directly into Stevens Creek or a combination of surface flow and drainage system inlets into one of the Stevens Creek discharge points.
In drainage Basin 6 (Backstretch Area) and Basin 7 (Race Track and Infield), the low-flow and first-flush runoff is manually diverted to the Del Mar Fairgrounds sewer system. Under standard practice, sanitary sewer systems are designed to serve sewer-generating facilities such as restrooms, restaurants, and offices. In certain instances, however, on-site low-flow runoff can be diverted to the sewer system for treatment in a sewer treatment plant. This procedure prevents flows stemming from areas of high pollution potential from entering the storm drain system and eventually the Pacific Ocean. Under existing conditions, horse wash water, first-flush stormwater from the Backstretch Area and from the area north of the arena and Surfside Race Place (when animals are present), and runoff from the recycling yard and car wash are diverted to the City of Del Mar sewer system. If a major storm event were to occur, excess water would be conveyed by the existing storm water system.
The current racing season takes place in the late summer when the likelihood of major storm events is low. The_ second__ race season and Breeder's Cup proposed under this Plan (see Chapter 4) wi,Il.,take..,placeM during the fall when storm events are more likely_ to occur. For this reason, the 22nd DAA is planning. '', additional onsite treatment of surface flows within Basin 6 and Basin 7 that may, under high-flow conditions, be discharged into Stevens Creek. Additionally, a new drainage system for the turf track (not a part of this Plan) will be constructed to remove water quickly and deliver flows to the infield ponds in a manner similar to the Polytrack drainage system for the main racetrack.
^~K'(A' Del Mar Fairgrounds Consent Order Compliance March 2013 ~ ~ ~ r J and Physical Improvements Plan Page 17 CHAPTER 2 FAIRGROUND OPERATIONS 2.2.4 Wastewater
Sewer service for the Del Mar Fairgrounds is provided by the City of Del Mar. The City of Del Mar owns and operates a collection system consisting of about 22 miles of sewer mains, 3 miles of force main, and three lift stations, which provide service to approximately 4,500 residents and other users (City of Del Mar Sanitary Sewer Management Plan [SSMP], 2010). The collected wastewater is transported to and treated by the City of San Diego through the San Diego Metro System. Capacity agreements for transportation and treatment limit the amount of wastewater that can be handled. The 22"d DAA is the largest user of the City of Del Mar's wastewater system. To assure system integrity during peak flows, the 22"d DAA and the City of Del Mar have entered into a wastewater disposal agreement on sewer flows. This agreement limits peak rate of flow, peak daily flow, and average daily flow and allows for testing of the 22"d DAA wastewater strength. As discussed in Section 2.3.3, the Del Mar wastewater system is relied upon to treat a portion of the low-flow runoff for the Del Mar Fairgrounds.

Plan under the Comprehensive CDP, it is anticipated that off-season temporary events held within the Del Mar Fairgrounds that are consistent with this Plan will be permanently authorized by the CCC pursuant to Section 3.3.B of the Consent Orders and not subject to further review by the CCC.
3.2 Existing Fairground Facilities
The Del Mar Fairgrounds offers a wide variety of facilities designed to accommodate temporary events. Most off-season temporary events are held within existing buildings west of Jimmy Durante Boulevard. However, a number of events utilize outdoor spaces which often serve as flexible-use areas. It is not uncommon for an event to have both an indoor and outdoor component. A few specialized events, such as circuses and carnivals, prefer to operate in large open areas (such as the main parking lot), which can temporarily accommodate large tents, fencing, bleachers, storage areas, lighting, and other support structures.
Figure 3-1 shows the enclosed and outdoor facilities within the Del Mar Fairgrounds along with temporary event data for the 2012-2013 off-season. A description of each facility is provided in the following section. Further description of the off-season temporary events is provided in Section 3.3, Description of Off-Season Temporary Events. 3.2.1 Enclosed Facilities
Existing enclosed and semi-enclosed facilities available for off-season temporary events are described in Table 3-1.
Off-season temporary events held within existing enclosed structures generally have limited potential to impact coastal resources and do not constitute "development" under the Coastal Act. Potential impacts to public access due to traffic and parking are discussed in the CRSR. 3.2.2 Outdoor Facilities
Existing outdoor facilities within the Fairgrounds typically used for off-season temporary events are described below:
Main Parking Lot
The main Fairground parking lot is an approximately 22-acre facility that is suitable for a variety of events. Certain specialized events, such as circuses and carnivals, prefer to operate in large open areas which can accommodate large tents, fencing, bleachers, storage areas, lighting, and other support structures. A Cirque du Soleil event, for example, is completely self-contained, within a layout space of approximately 4.5 acres. Generally, parking for events located in the main parking lot is easily accommodated in the remaining portions of the main lot.
Del Mar Fairgrounds Consent Order Compliance March 2013 /\TKI N5 and Physical Improvements Plan Page 22 CHAPTER 3OFF-SEASON TEMPORARY EVENTS
Chapter 3 OFF-SEASON TEMPORARY EVENTS
3.1 Overview
The Consent Orders specifically require that the 22°d DAA:...shall submit, and allow to be processed to Commission hearing under its normal procedures, a complete coastal development permit application for permanent authorization of typical short-term events to be held within the Fairgrounds that DAA wishes to retain or continue to perform and which CCC staff has determined, after consultation with DAA, a permit to be necessary. This comprehensive permitting requirement excludes the Fair and Races as defined in Section 3.2.A.3 of these Orders.
The 22"d DAA has initiated this process by delivering to CCC staff a list of all the off-season temporary events presently occurring during the 2012-2013 off-season with descriptive information and analysis designed to assist CCC staff in determining if any of the off-season temporary events would require a coastal development permit. Materials provided to CCC staff included:
1. A scaled site plan showing the location of all temporary events in relation to identified sensitive habitat areas (see Figure 3-1, Typical Off-Season Temporary Event Locations); 2. A chart showing event duration and concurrency (day-by-day intensity of use)for the 2012-2013 off-season (available at CCC office); and 3. A table showing the major recurring off-season temporary events with estimates of daily ~ attendance and parking (see Table 3-2, Del Mar Fairgrounds Major Recurring Off-Season Temporary Events).
To date, no specific temporary event, other than the proposed second race season discussed in Chapter 4, has been determined by the CCC to require a coastal development permit.
This Plan assumes that temporary events held in a facility designed specifically to accommodate such events will not typically require Coastal Commission approval. The potential impacts to coastal resources, as expressed by CCC staff are generally the cumulative effects of very large or simultaneously occurring temporary events where the potential exists to exhaust existing parking facilities, impact identified wetland areas, degrade water quality, or cause significant visual impacts.
This Plan describes the typical temporary events that occur during the off-season, the facilities used to accommodate them, and the parking management associated with such events. Site development standards have been incorporated into the Plan to protect coastal resources. With the approval of this

The western side of the West Parking Lot is located in proximity to San Dieguito Lagoon, but is buffered by a chain link fence, perimeter roadway and an environmentally sensitive habitat buffer area of varying width along the lagoon shoreline. The variable width buffer is a requirement of Section 3.4.C.3 of the Consent Orders and is currently defined by a wooden post and rail fence. Stevens Creek which flows into San Diego Lagoon just west of the West Parking Lot is located approximately 50 feet from the West Parking Lot at its closest point. The West Parking Lot is visible from the Camino Del Mar Bridge but is partially obscured by the train trestle crossing the San Dieguito Lagoon Channel.
Two locations in the West Parking Lot have. been used during the Fair and Race season for outdoor concerts. The Coors Light Rock On Stage, when in use during the Fair season, is located in the southern portion of the West Parking Lot. The stage location is approximately 265 feet from the San Dieguito River and 250 feet from Stevens Creek. The Del Mar Thoroughbred Club (DMTC) Stage, when in use for DMTC race meet concerts, is located in the northwest corner of the West Parking Lot. This stage location is approximately 900 feet from the San Dieguito River and 120 feet from Stevens Creek.

Green Parking Lot
The Green Parking Lot is a triangular shaped property located on the western edge of the Fairgrounds just south of the Training Track. During the Fair and Races the lot is used for visitor parking. During the off-season the lot is used primarily for parking, temporary vehicle storage, logistics and the 22"d DAA's annual Scream Zone event. Due to the height of the railroad berm the Green Parking Lot is not visible from roadways outside the Fairgrounds.

EOL Area 1
EOL Area 1, which as defined in Coastal Development Permit Application 6-12-067, is an approximately 7.0 acre area located on the northern portion of the EOL. Typical off-season temporary events in EOL Area 1 include a Pumpkin Patch carnival event and a Christmas Tree sales event. As described in CDP application 6-12-067, EOL Areas 2 and 3 may also be utilized for temporary events subject to the conditions of the permit. Generally, however, off-season temporary events will be confined to EOL Area 1. As described in the Consent Orders, the entire EOL has been identified as an area of concern with respect to adjacent wetland resources and potential disturbance of wetland resources on the site. Mitigations for potential impacts to coastal resources in the vicinity of the EOL will be addressed by CDP 6-12-067 and incorporated into this plan by reference.
West Parking Lot
The West Parking Lot is an expansive paved area located on the southwest corner of the Fairgrounds. During the Race Season the West lot is used as a visitor parking lot. During the Fair season the lot is used

5K and 10K runs. The Racetrack is also utilized for the 22"d DAA's annual Holiday of Lights event. Visitors may drive through the Racetrack or take a hayride to view themed light displays. Infield
The Infield area is amulti-purpose outdoor area located on the east side of the Racetrack. During the Fair season the Infield is used for smaller carnival rides and attractions for kids. During the off-season the Infield may be used for a few outdoor events such as mud runs, obstacle courses, and outdoor games. The Infield is often used in tandem with the Infield Pavilion, an indoor facility also located in the racetrack infield. Exhibit Hall North Parking Lot and Bing Crosby Parking Lot
The Exhibit Hall North Parking Lot and Bing Crosby Parking Lot are multi-purpose outdoor areas located north of the existing Exhibit Hall and Bing Crosby Hall, south of Avenida de Las Palmas. The lots are also part of the Carnival Parking Area described in Table 1-1 (Existing Fairgrounds Parkingj. During the off- season, these facilities are used primarily in conjunction with temporary events held in the Exhibit Hall and Bing Crosby Hall. The two lots are situated in the area to be cleared for the construction of the new Exhibit Building (see Section 5.2.3, Exhibit Building with Rooftop Sportsfields) and will no longer be available as outdoor temporary event facilities. The lost parking spaces will be offset by subterranean parking and indoor valet parking in the new Exhibit Building. Outdoor East O'Brien Hall
The Outdoor East O'Brien Hall area is located on the east side of O'Brien Hall not far from the main gate. During the off-season this facility is used primarily in conjunction with temporary events held in the O'Brien Hall. This area will be cleared to make way for the new Exhibit Building (see Section 5.2.3).
Ring Lot 1
Ring Lot 1 is a small triangular shaped area located between the Wyland Hall and Expo Center. During the off-season the lot is occasionally used as an outdoor extension for temporary events utilizing the adjacent Activity Center.
3.3 Description of Off-Season Temporary Events
Every year the 22"d DAA hosts approximately 200 to 300 off-season temporary events. The number of events varies from year-to-year depending on demand. Over the past 20 years the number of off-season temporary events has increased steadily. In recent years, however, off-season temporary event bookings have been fairly level with no significant increase in attendance. The proposed physical improvements described in Chapter 5 (Planned Physical Improvements) would result in a net increase in exhibit hall space of 26,220 sf, all of which would be available for temporary events during the off- season. ~--

season, Del Mar Fairgrounds operates much-like aconference/trad_e show facility. Attu During the off- the ...~.,_~ _...__.,w _.._ _. . Fairground activities, including the Fair and Races, are temporary events and must be programmed into the available facilities. These facilities, including parking and logistical areas, place constraints on what can be accommodated at any one time.
Off-season temporary events range in size from private weddings and bar mitzvahs to major trade shows and community events open to the general public. On any given day during the off-season the number of temporary events will range from zero to approximately eight events. The median number of daily events is approximately three. The number of daily events occurring simultaneously tends to peak towards the weekends (Friday, Saturday, and Sunday).
Event durations vary from less than one day to over four weeks. Many events have set-up and take down periods when the event is not open to the public. Logistical activity occurring during the set-up and take-down time periods is important because it may preclude other temporary events from taking place at the same time.
The various off-season temporary event types are listed in Table 3-1 (above) along with the current capacity of the existing facilities. 3.3.1 Potentiallmpacts .__ In general, event size, location, and the ~~.mulative increase in parking demand ..ire more.. important than` event type in assessing potential impacts to coastal resources. The vast majority of off=season temporary events are held in enclosed facilities. The largest events such as the spring car show may ~ , utilize several facilities throughout the Fairgrounds including the EOL and GDR for overflow parking. A i~:> list of the major recurring off-season temporary events is provided in Table 3-2. The recurring events are shown in order of average daily paid parking receipts.
Off-season temporary events occurring indoors have no significant potential to impact wetlands, water quality, or visual resources. However, all indoor events contribute to traffic and parking demand. For this reason a traffic study was prepared (Traffic Analysis Report for the Comprehensive CDP, LLG, 2013) to assess the need for traffic and parking mitigations that might be needed to accommodate off-season temporary events.
A smaller but significant portion of the off-season temporary events. utilize outdoor facilities (see description in Section 3.2.2 Outdoor Facilities). Outdoor off-season temporary events located well within the fairgrounds interior have little potential to impact wetlands, water quality, or visual resources. The interior facilities include the Racetrack, Infield, Exhibit Hall North Parking Lot, Bing Crosby Parking Lot, Outdoor East O'Brien Hall and Ring 1 Lot. These facilities are neither visually prominent nor located adjacent to identified wetlands.
The main parking lot, which lies east of the entry gate, is also located away from wetland areas but does have a significant visual exposure from Jimmy Durante Boulevard and I-5. Outdoor facilities with some visual exposure and/or proximity to wetlands include the West Parking Lot, Green Parking Lot, Training Track and the EOL. Potential impacts to coastal resources from off-season temporary events occurring in f , these facilities are discussed in the CRSR. ~' ~, ~~ ~ ~R' e~° ''

The potential for parking impacts related to off-season temporary events within outdoor facilities is essentially the same as enclosed facilities, except that the event itself, if occupying a parking area, may reduce the number of available spaces. A description of the 22"d DAA's parking and traffic management activities during the off-season is provided in Section 3.4 below.
3.4 .Parking and Traffic Management
As discussed in Section 2.2.2, approximately 10,550 parking spaces are available for use during the off- season. The parking is distributed in 12 separate parking areas within the Fairgrounds including overflow
n~~('At C Del Mar Fairgrounds Consent Order Compliance March 2013 ~ ~ ~~ ~ rJ and Physical Improvements Plan Page 30 CHAPTER 3OFF-SEASON TEMPORARY EVENTS
According to 22~d DAA Parking and Traffic Managers, use of the EOL has little or no impact on the Surf can and Turf area. Ther utilization,_...... of_~._._. the___. GDR,_..~.. if necessary,_ _...__. is done in phases_. so that the Golf Range continue its driving range business by shifting patrons to the east. The Surf and Turf parking area is separate from the EOl and is not affected by off-season events.
The parking and traffic management provided by the 22"d DAA is designed to reduce traffic congestion and the possibility of drivers opting to find alternative parking in the surrounding neighborhoods. The size of the Fairgrounds, the substantial grade separation from Via de la Valle, and the location of the entrance far from neighboring residential and commercial areas, makes it inconvenient for Fairground patrons to park on public streets. These factors are even more pronounced on the west side of the Fairgrounds in the neighborhoods closest to the beach.
Additionally, off-season temporary events occur outside of the summer season, during the fall and winter when ambient traffic volumes in the beach communities are significantly lower. Average daily traffic volumes attributable to off-season temporary events are substantially less than for the Fair and Races. When traffic volumes for individual off-season temporary events do approach those of the Fair and Races, they are of much shorter duration. Potential impacts to public access related to parking and traffic generated by off-season temporary events are discussed in the CRSR.
^~~(I n'S Del Mar Fairgrounds Consent Order Compliance March 2013 ~ ~ ~~ ~ ~~ and Physical Improvements Plan Page 32 CHAPTER 3OFF-SEASON TEMPORARY EVENTS
sites. Overall, on a sustained basis, parking demand during the off-season is substantially lower than for the Fair and Races. A few large events may, on occasion, require use of the EOL and GDR parking areas. The SOL is no longer used for off-season parking.
Parking management for the Fairgrounds is a coordinated effort between the 22"d DAA's Events Department, Parking Department and Traffic Department. During the off-season, the Events Department (responsible for event planning) assesses the parking need when booking events. Contact is made with the previous venue where the event was held to analyze and evaluate the traffic and parking information as well as other important event information. The Events Department estimates the expected attendance based on the promoter's previous show to determine parking requirements and other planning needs. Coordination between departments is maintained through weekly in-house event meetings to review event orders and plan for upcoming events.
Efficient utilization of the existing parking facilities is achieved through the use of "directed" parking. For major events, the Parking Department assigns traffic directors to direct inbound traffic to each parking aisle. The vehicles are then directed into the next available parking space thereby maximizing the use of all available parking spaces. Parking staff closely monitors turnover from key vantage points to direct traffic directors to back fill vacant spaces. As required in the 22°d DAA Parking Department Operations Plan, throughout the day, supervisors and traffic directors closely monitor the parking demand by gauging the flow of traffic by communicating with the street traffic controllers, monitoring turnover, patrolling the parking lots and utilizing all available space to accommodate the event. ,.n, ~,~~~s ., Prior to anticipated heavy traffic days, a traffic plan is prepared and implemented in coordination with t z~~~`~~~~~N y the County Sheriff's Department and City of San Diego Special Events Department. The traffic plan is ~r~`"~ ~-~ designed to expedite the flow of traffic from the freeway off-ramps and surface streets into the ''fig Fairgrounds parking lots. The Parking Department also coordinates with the Caltrans Traffic t Management Center to activate freeway signage as needed to provide helpful traffic information and divert traffic to off-site lots where necessary. To date, the 22"d DAA has never needed to use off_ -site lots ~"~'~,~~~~ ~ ~' .. to accommodate parking for off-season temporary events. While this \plan does not anticipate such a `~~~,?t`~~"` need; the same off-site parking lots and shuttle service utilized during the Fair can be implemen#ed if it' is anticipated that the parking requirements for an events) will exceed the number of spaces within the Fairgrounds. The 22"d DAA Parking and Traffic Managers have an exemplary record of meeting the traffic and parking challenges of the annual Fair and Races and have been acknowledged for their talents by Caltrans, the San Diego County Sheriff's Department and the City of San Diego Special Events Department. ~., 5..~
The use of the EOL and GDR is typically anticipated in advance based on the number of events booked, ~,~ past history associated with the event(s), expected attendance and background information from the promoters) and previous venue. Based on the established pre-planning for events, including staffing levels, the overflow lots are available to be put into service as the need arises. With the exception of the second race season (including Breeder's Cup) discussed in Chapter 4, no significant increase in the use of the EOL and GDR for overflow parking is anticipated during the off-season. However, the EOL and GDR ?~ will remain available for overflow parking use without limitation.
n~~(I~ ( Del Mar Fairgrounds Consent Order Compliance March 2013 ~ ~ ~~ J and Physical Improvements Plan Page 31 CHAPTER 4 SECOND RACE MEET
Chapter4 SECOND RACE MEET
4.1 Overview
While the previous chapter describes the ongoing off-season temporary events as required in the Consent Orders, this chapter proposes a second race meet outside the period in which the regular Fair and Races are held. The timing, scale and characteristics of the second race meet set it apart from the other off-season temporary events. For this reason, the Comprehensive CDP application includes a request for CCC approval of the second race meet, and it is included in the Plan. This chapter describes the proposed temporary events which comprise the second race meet and identifies water quality, parking and traffic management issues which must be addressed to avoid potential impacts to coastal resources.
4.2 Description of Second Race Meet
Changes in the horseracing industry, including the potential closure and redevelopment of Hollywood Park in the Los Angeles area, have created opportunities for new racing events at the Del Mar Fairgrounds. Since these opportunities exist in potential only, the 22"d DAA must remain flexible. At this time, the 22"d DAA is seeking to hold an approximately five-week second race season beginning in late October or early November. Racing would occur on an average of four days per week. The racing dates, as well as the racetrack selection, will be determined by the California Horse Racing Board (CHRB) and are not under the control of the 22"d DAA.
The second race meet would take place within the Del Mar Fairgrounds racetrack. No additional seating capacity is required or proposed. Attendance during the regular summer racing period averages about 17,000 persons per day. Average daily attendance for the second race meet is estimated to be about 60% of the summer period or about 10,000 persons per day. Adequate parking exists to handle projected attendance, but occasional use of the EOL and GDR overflow lots will be required. ~h tJ ~~: 4.2.1 Breeder's Cup Race Event
Included within the second race season is the Breeder's Cup World Championship. The Breeder's Cup is a prestigious two-day racing event similar to the Kentucky Derby, Preakness Stakes, or Belmont Stakes. The race location changes each year, however, some locations have hosted the event more frequently. From 2008 to 2012 the Breeder's Cup has been held in either Santa Anita Park, CA or Churchill Downs,
/~I~('~ C Del Mar Fairgrounds Consent Order Compliance March 2013 ~ ~ ~~ J and Physical Improvements Plan Page 33 CHAPTER 4 SECOND RACE MEET
KY. The Del Mar Racetrack has never hosted the Breeder's Cup, but with minimal upgrades to comply with Breeder's Cup event specifications, the facility has the potential become one of the favored locations.
The Breeder's Cup is held either in the last week of October or first week of November. While the race itself is a two-day event, other activities leading up to the event would bring additional people to the Fairgrounds. Attendance over the course of the event may reach 90,000 people. Peak daily attendance would be about 45,000 people. Other off-season temporary events would be curtailed during the Breeders Cup's period. Use of the EOL and GDR overflow lots is anticipated.
4.3 Water Quality Improvements
To accommodate a second race during the rainy season, additional water quality improvements will be needed for the Backstretch, Polytrack, Turf Track, and Infield portions of the Del Mar Fairgrounds. The water quality improvements are designed to treat runoff from the Polytrack to meet water quality objectives and to ensure compliance with Confined Animal Feeding Operations (CAFO) regulations during wet weather conditions. These improvements are further described in Chapter 6 General Development Standards. While designed for the second race, the water quality improvements would serve a large portion of the Fairgrounds and would result in less year round runoff entering the Del Mar wastewater treatment system. With the improvements fully in place, the potential exists to reduce existing pollutants in Stevens Creek to meet acceptable water quality standards on a year round basis. Potential impacts to water quality from the second race meet are discussed in the CRSR.
4.4 Parking and Traffic Management
Parking management for the second race meet will be provided in the same manner as described for the off-season temporary events (see Section 3.4, Parking and Traffic Management) except that the available parking areas will be the same as for the Race season.
These management techniques include: ■Coordination between 22"d DAA Events, Parking, and Traffic Departments ■Evaluation of information from previous race events ■Estimations of expected attendance ■Use of directed parking to achieve efficient utilization of existing parking facilities ■Close monitoring of parking turnover to achieve efficient back-fill of vacant spaces ■Continual monitoring of parking demand by communication with street controllers ■Preparation of traffic plan to expedite flow of traffic from freeway off-ramps and surface streets into Fairgrounds parking lots. ■Coordination with Caltrans to activate freeway signage as needed.
n~~('n' C Del Mar Fairgrounds Consent Order Compliance March 2013 ~ ~ ~~ ~ r~ and Physical Improvements Plan Page 34 CHAPTER 4 SECOND RACE MEET
It is anticipated that the EOL and GDR parking lots will be utilized only a few times during the second ~ , race meet, most likely on the opening day and during the two-days of the Breeder's Cup event. As with i ; the regular Race season, the need for off-site parking is not expected. Specific parking and traffic `~, ' management mitigations are provided in Chapter 6, General Design Standards. Potential impacts to ~'- publicaccess related to parking and traffic generated by the second race are discussed in the CRSR.

Chapter 5 PLANNED PHYSICAL IMPROVEMENTS
5.1 Overview
In addition to the off-season temporary events required by the Consent Orders, this Plan identifies 11 physical improvements designed to upgrade existing facilities and ensure a quality experience for users of the Del Mar Fairgrounds and adjacent Surf &Turf areas. These physical improvements are needed to support the full range of off-season temporary events described in Chapters 3 and 4 and are of critical importance in protecting coastal resources from impacts associated with temporary events. Each improvement is conceptually described, at the plan level, to convey its potential, either individually or cumulatively, to impact coastal resources. Where appropriate, specific site development standards have been incorporated into the Plan to protect coastal resources. General development standards applicable to all physical improvements, off-season temporary events, and the second race meet are provided in Chapter 6(General Development Standards)
Approval of this Plan under a Comprehensive CDP does not imply Coastal Commission approval of any "; identified physical improvements. Each development will require an individual CDP under the Coastal ~'`,~ Act. The purpose of the Plan is to reduce uncertainty regarding the 22"d DAA long-range development ~ ~_ aspirations and to provide a framework to assess potential cumulative impacts to coastal resources. An added benefit of the Plan will be a reduction in the level of coastal permit review for projects found consistent with the Plan.
Potential impacts to coastal resources from physical improvements are discussed in the CRSR.
5.2 Conceptuallmprovements
The following conceptual improvements are in various stages of planning and are anticipated to be submitted for CCC approval over the course of an approximate 20-year period. Due to the conceptual nature of the improvements, project details may ultimately vary from those described but the site development standards of this Chapter and the general development standards of Chapter 6 shall be met. Figure 5-1 illustrates the conceptual improvement sites within the Del Mar Fairgrounds.
n~~l A'C Del Mar Fairgrounds Consent Order Compliance March 2013 ~ ~ ~ r J and Physical Improvements Plan Page 37 CHAPTER 5 PLANNED PHYSICAL IMPROVEMENTS 5.2.1 Solana Gate Road Realignment
The Solana Gate currently provides direct access from Via de la Valle to the Backstretch area, Training Track, Racetrack and interior parking areas within the Del Mar Fairgrounds.
Conceptual plans include a realignment of Solana Gate Road to allow more efficient use of the Backstretch facilities and the addition of a sidewalk to afford better pedestrian access. The project is also expected to reduce traffic congestion on Via de la Valle by reducing queuing delays for vehicles waiting to make a left turn into the Solana Gate entrance. The preliminary concept is shown in Figure 5-Z
The realignment will incorporate a smoother horizontal and vertical transition from Via de la Valle to the. northwest corner of the Racetrack. The existing two-lane roadway will be widened to three lanes, for a total of 36 ft in width, and will include a new Americans with Disabilities Act (ADA) compliant sidewalk and curb paralleling the roadway on the west side only. New lighting and guard railings will be installed to enhance pedestrian safety.
Grading will be required on the east and west sides of the new road, including filled slopes on the east and south sides. Keystone retaining walls on the west side will be used to minimize encroachment into existing wetlands. Stevens Creek, which crosses the roadway, will continue to flow through an existing culvert to be incorporated into the new roadway design. An equestrian tunnel will pass under the new roadway linking the Backstretch facilities to the Training Track. Site Development Standards
Wetland Mitigation Standards
The 22"d DAA will implement the following wetland impact mitigation for the Solana Gate road realignment:
1. Wetland impact mitigation will include, at minimum, creation or substantial restoration of wetlands of the same type as the affected wetland or similar type of habitat within the San Dieguito Lagoon area. It is anticipated that the impacts would be very small ranging from 0.1 to 0.3 acres. However, the final acreage of wetland habitat impacted will be determined based on the approved project in the Coastal Development Permit.
2. Prior to issuance of the Coastal Development Permit, the 22"d DAA will identify an area of disturbed or degraded wetland habitat of equivalent or superior type and acreage sufficient to provide mitigation of the wetland impacts according to the following ratios (number of acres of created or restored habitat required for each acre of wetland habitat impacted), as applicable:
Seasonal wetlands 3:1 Freshwater marsh 3:1 Riparian areas 3:1 Brackish water/estuarine 3:1
~~~('^' C Del Mar Fairgrounds Consent Order Compliance March 2013 ~~ ~ r J and Physical Improvements Plan Page 38 CHAPTER 5 PLANNED PHYSICAL IMPROVEMENTS
3. These mitigation ratios will be minimum standards unless the 22nd DAA provides evidence establishing, and the CCC finds, that creation or restoration of a lesser area of wetlands will fully mitigate the adverse impacts of the project. However, in no event will the mitigation ratio be less than 2:1 unless, prior to the development impacts, the wetland creation or restoration proposed as project mitigation is completed and is empirically demonstrated, based upon a report provided by the 22nd DAA from a qualified biologist or resource specialist, to meet performance criteria that establish that the created or restored wetlands are functionally equivalent or superior to the impacted wetlands.
4. Prior to issuance of the coastal development permit, the 22nd DAA will submit wetland habitat creation, restoration, management, maintenance and monitoring plans for the proposed wetland mitigation area prepared by a qualified biologist and/or resource specialist. The plans will provide a 100 foot restored buffer where feasible as measured from the upland limit of the wetland area, and at a minimum include ecological assessment of the mitigation site and surrounding ecology; goals, objectives and performance standards; procedures and technical specifications for wetland and upland planting; methodology and specifications for removal of exotic species; soil engineering and soil amendment criteria; identification of plant species and density; maintenance measures and schedules; temporary irrigation measures; restoration success criteria; measures to be implemented if success criteria are not met; and long-term adaptive management of the restored areas for a period of not less than 3 years, unless otherwise conditioned by the CCC. No buffer, or a buffer of less than 100-feet, would be acceptable if the wetland mitigation area occurs on a constrained site within or adjacent to the Fairgrounds, (such as Stevens Creek). Such constraints include, but are not limited to, steep slopes, roadways, railroad or roadway berms, or other physical features of the developed landscape. The CCC will determine that the proposed restoration site is of equivalent or superior type and acreage to the impacted wetland habitat.
5. The area of wetland habitat to be restored will be restricted from future development and permanently preserved through the recordation of an open space deed restriction that applies to the entire restored area. The habitat restoration will be carried out prior to or concurrently with construction of the development project. In any case, the wetland restoration or creation project will be complete prior to the issuance of certificates of occupancy for any structures approved in the Coastal Development Permit.
Landscaping Standards
The 22nd DAA will implement the following specific landscaping standards for the Solana Gate Realignment project:
■Submit for the review and written approval of the CCC Executive Director, a plan for landscaping. The plan will be prepared by a licensed landscape architect and include, at a minimum, the following:
1. All new vegetation planted on the site will consist of native, drought-tolerant, and non- invasive plants which will not have an adverse impact on nearby wetlands and ESHA. No plant species listed as problematic and/or invasive by the California Native Plant Society, the
/~t~['nt C Del Mar Fairgrounds Consent Order Compliance March 2013 ~ ~ ~~ ~ r J and Physical Improvements Plan Page 41 CHAPTER 5 PLANNED PHYSICAL IMPROVEMENTS
California Invasive Plant Council, or as may be identified from time to time by the State of California will be employed or allowed to naturalize or persist on the site. No plant species listed as `noxious weed' by the State of California or the U.S. Federal Government will be utilized. All required plantings will be maintained in good growing conditions throughout the life of the project, and, whenever necessary, will be replaced with new plant materials to ensure continued compliance with the landscape plan.
2. A plan showing the type, size, and location of all plant materials that will be on the developed site, the irrigation system, topography of the developed site, and all other landscape features.
3. A requirement that five years from the date of issuance of the Coastal Development Permit, the applicant shall submit for review and written approval of the CCC Executive Director, a landscape monitoring report, prepared by a licensed Landscape Architect or qualified Resource Specialist, that certifies the on-site landscaping is in conformance with the approved landscape plan. The monitoring report will include photographic documentation of plant species and plant coverage.
(See also Chapter 6, General Development Standards). 5.2.2 RV Lot Improvements
The existing Surf &Turf RV Park located on the east side of Jimmy Durante Blvd just north of the Crosby Gate provides 62 RV parking spaces. Water and electricity hook-ups are currently in place. Conceptual plans include the provision of sewer hook-up facilities to serve the same existing 62 RV parking spaces. The connections will be made to an existing sewer line which runs through the property. The existing RV parking spaces are shown in Figure 5-3(RV Lot Improvement Sites).

Three existing exhibit halls and a tent structure on the south side of the Del Mar Fairgrounds are aging and need to be replaced. These include the Pat O'Brien Hall, Bing Cros~Hall,._.__ "Exhbi.t"-Ma.0 and the Seaside Pavilion. The existing exhibit halls range from approximate y 29.5 ft to 45 75 ft in height...,.. ~___ _~ ~~.~ _._e..~_ Conceptual plans include the demolition of the existing exhibit halls and the construction of a new exhibit building at the same general location. The new exhibit hall will consist of one building with the ability to be cordoned-off into three separate areas, each providing approximately 66,000 square feet of exhibit space (198,000 sf total) for a net increase of 26,220 sf of exhibit space. The preliminary design concept is shown is Figure 5-4.
The new exhibit hall will include break-out rooms and a rooftop sports field available for public use during the off-season. A portion of the exhibit hall will contain an upper level terrace on the north side of the building. The terrace would overlook Avenida de Las Palmas—the multi-use roadway running through the main exhibit area just south of the Grandstand Complex. The maximum height of the exhibit hall will be approximately 51.5 ft at grade (three stories).
The new exhibit hall will feature Mission style architecture consistent with the Grandstand Complex. Elements from the demolished Clock Tower (i.e., decorative tiles) will be incorporated into the design.
Approximately 1,156 new semi-subterranean parking spaces will be provided under the new exhibit hall. Fifty-eight (58) RV hook-ups currently on the site will be relocated and incorporated into the design.
Site Development Standards
Habitat Buffer ■The new exhibit hall shall be built in conformance with the one hundred (100) foot wide environmentally sensitive habitat buffer (100-feet from the from wetlands and/or the San Dieguito River) as defined in Section 3.4.C.3 of the Consent Orders and depicted in Figure 6-1 (Habitat Buffersj. Only the following uses shall be permitted within the buffer: 1. Restoration and maintenance activities (e.g. habitat, trails, fencing, stormwater drainage facilities) < $,f; ~ 2. Public access on approved trails c ~_~ 3. Temporary walking and running events confined to approved trails ~ .~ ,~ (See also Chapter 6, General Development Standards). ` '

Rooftop Lighting ■Rooftop lighting shall be low level only, with light standards not to exceed 15 feet in height. Shielding using the best available visor technology and design that minimizes light spill, and glare impacts to public views and wildlife shall be employed. Light spill shall not exceed 0.5 foot candles measured at the northernmost edge of the 100-foot Buffer for the Exhibit Hall. ■No sports field lighting shall be allowed. ■During the off-season, rooftop lighting shall be turned off no later than 8:00 p.m., except that the rooftop lighting may be used until 10:00 p.m. for not more than 122 days per year. (See also Chapter 6, General Development Standards). 5.2.4 Entry Gate/Administration Building
In order to accommodate the proposed Exhibit Hall (discussed above), provide adequate space for the 100-foot buffer and ensure that the structure is not located within the floodway of the San Dieguito River, several existing structures would need to be demolished. These include office buildings used by the 22"d DAA's Exhibits Department, Operations Department and Production Department. Demolition of the existing Marketing/Human Resources (HR) structure, which includes the existing Board Room and Lounge, would also be required. Additionally, to increase efficiency and accessibility to patrons, the ticket box office would need to be relocated closer to the entry gate and main parking lot.
Conceptual plans include a new entry gate and a relocated ticket box office with replacement administrative offices integrated into two buildings located on the north and south sides of the gate. A retail shop area will be located in the south building on the interior -side of the gate. Approximately 58,000 sf of usable space will be provided in the three above ground stories and basement. Mission style architecture consistent with the main fairground structures will be used throughout. The preliminary design concept is shown in Figure 5-4.
(See also Chapter 6, General Development Standards). 5.2.5 Relocated Maintenance Yard Structures
The existing maintenance buildings/yard is located adjacent to the San Dieguito River on the south side of the Del Mar Fairgrounds. Relocation of the buildings/yard is needed to make room for the proposed new exhibit hall complex and the 100-foot buffer required by the Consent Orders. The buffer ensures that the proposed structures will not be located within the floodway of the San Dieguito River.
Conceptual development plans include three new maintenance buildings/yards referred to as Site A, Site B, and Site C. .
Site A will be the location for a new two-story, 28,000 sf facility located at the west end of the Grandstand Complex in an area currently referred to as the West Lawn (see Figure 5-5, Conceptual Site A Maintenance Building Floor Plan and Elevations). The new building will have two floors with a height of approximately 34 ft above grade. The lower floor will be used for food service catering, receiving, and storage. The second floor will provide ameeting/function area.
Del Mar Fairgrounds Consent Order Compliance March 2013 /\TKI N S and Physical Improvements Plan Page 47 CHAPTER 5 PLANNED PHYSICAL IMPROVEMENTS
Site B plans consist of two buildings (north and south), a maintenance yard, a vehicle wash rack, a fuel station, and a small parking area. The new facility will be located west of the stable area on the north corner of the Racetrack near the Solana Gate entrance (see Figure 5-6, Conceptual Site B Maintenance Buildings Site and Floor Plans). The new facility would function as a shared 22"d DAA and Del Mar Thoroughbred Club facility. Existing structures on the site used by the Del Mar Thoroughbred Club would be demolished to make way for the new facility.
The north building will be two stories, approximately 34 ft above grade with the highest architecture feature reaching approximately 44 ft above grade. An open-air courtyard will be provided on the ground floor in the center of the building. Solar panels will be incorporated into the building to generate electrical energy. The ground floor will primarily be used as a maintenance shop, and the second floor will be used for operations and administrative offices for the 22nd DAA and Del Mar Thoroughbred Club.
The south building will be one story, approximately 28 ft above grade, and will be used for a maintenance shop, storage, and receiving.
The approximately 6,300 sf maintenance yard will be located west of the north building at ground level.
An existing fuel station and vehicle wash rack for Del Mar Fairgrounds maintenance use is located directly west of the north and south buildings. The wash rack will be covered and equipped with appropriate Wastewater Treatment BMPs, including a clarifier for oil and water separation and solids removal.
Site C will be the location for an approximately 32,000 sf single-story open-air steel structure located in the stable area on the north side of the project site near the Solana Gate entrance. The new structure will be approximately 30 ft above grade. The facility will be used for recycling, landscaped storage and landscaped equipment, and general storage.
(See also Chapter 6, General Development Standards). 5.2.6 Health Club/Sports Training Facility.
The 22"d DAA properties include an approximately 0.7-acre vacant site located adjacent to I-5 in the SurF and Turf area just north of the existing Mini Golf facility.
Conceptual development plans include the construction of a 60,000 sf Health Club/Sports Training Facility on an approximately 1.0 acre site consisting of the 0.7 acre vacant site and an approximately 0.3 acre portion of the tennis club facility to the north. Three existing tennis courts would be removed to accommodate the new facility. The building will have three stories; 48 feet in height, with an allowance for architectural features to reach a maximum height of 75 ft. Architecturally, the structure will follow ~.~~~~~f~ r, f.r~ the Mission style characteristic of buildings within the Del Mar Fairgrounds. The preliminary design concept is shown in Figures 5-7 and 5-8.

The health club will occupy approximately 25,000 sf while the sports training facility will use approximately 35,000 sf. Associated facilities will include a rooftop complex to accommodate a field for various sports activities. The sports training facility will be available for such uses as baseball camps and soccer camps.
Access will be provided from a driveway off Jimmy Durante Boulevard. The project includes 110 parking spaces that will be shared with the adjacent Golf center (driving range and mini-golf). Additional space to meet City of San Diego parking requirements (5 spaces per 1,000 square feet [190 spaces]) can be accommodated on the adjacent EOL. Site Development Standards
Parking
■When the EOL is in use for overflow parking, the 22nd DAA staff shall cordon off an area sufficient to accommodate 190 additional parking spaces for use by the Health Club/Sports Training Facility. This accommodation will be required as part of the Traffic Control Plan and the Health Club/Sports Training Facility operating program.
Rooftop Lighting
■Rooftop lighting shall be low level only, with light standards not to exceed 15 feet in height. Shielding using the best available visor technology and design that minimizes light spill, and glare impacts to public views and wildlife shall be employed. Light spill shall be controlled so there is no net increase in ambient light levels within the Surf and Turf area.
■No sports field lighting shall be allowed.
■During the off-season, rooftop lighting shall be turned off no later than 8:00 p.m., except that the rooftop lighting may be used until 10:00 p.m. for not more than 122 days per year.
(See also Chapter 6, General Development Standards). 5.2.7 Semi-Permeable Paving of EOL
The EOL is an approximately 23-acre dirt lot used primarily for overflow parking, some temporary events, and fairground logistics including hay bale and horse trailer storage. A coastal development permit application (6-12-067), required by the Consent Orders, has been filed by the 22"d DAA to establish entitlement to continue these traditional uses under newly proposed site development criteria addressing permitted uses, height, lighting, water quality, noise, signage, landscaping and wetland buffers. Under the proposed permit the EOL is to remain a permeable dirt surface, although Section 3.2.8. of the Consent Orders contemplates the installation of semi-permeable surfacing. This condition will remain until the permit is amended to allow for the paving of the EOL as described in this Plan.
Conceptual development plans include paving of the EOL (using semi-permeable paving) to provide approximately 3,200 all-weather parking spaces, a tram path, and pedestrian circulation. Access to the parking area will be provided by two driveways off Jimmy Durante Boulevard and one driveway from the
n~~l A'C Del Mar Fairgrounds Consent Order Compliance March 2013 ~ ~ ~ r J and Physical Improvements Plan Page 53 CHAPTER 5 PLANNED PHYSICAL IMPROVEMENTS
proposed Health Club/Sports Training Facility east of the parking area. The preliminary design concept is shown in Figure 5-9.
Stormwater runoff would be treated using a combination of adjacent grass swales, concrete swales, and a bioretention basin. Water quality BMPs and wetland buffers consistent with the previous coastal development permit would be incorporated into the design. Site Development Standards ■All site development standards approved under CDP 6-12-067 shall also apply to the semi- permeable paving of the EOL, provided an amendment to CDP 6-12-67 is approved by the CCC to allow semi-permeable paving of the current dirt surface. Approval of this Plan by the CCC acknowledges the acceptability of semi-permeable paving, in concept, at a future date subject to the review and approval of final plans under a subsequent CDP. ■All activities and events on the EOL will be operated in conformance with the 22°d DAA Storm Water Management Plan and Erosion Control Water Quality BMP Plan.
■The 22nd DAA will incorporate project -specific design, source control, and treatment control BMPs to control predictable pollutant runoff, including an operations and maintenance plan for the prescribed structural BMPs to ensure their long-term performance.
■The 22"d DAA will further adhere to the General Industrial Storm Water Permit, NPDES Phase II permit, and incorporation of BMPs through compliance with the latest version of the City of Del Mar SUSMP requirements.
(See also Chapter 6, General Development Standards). 5.2.8 Parking Structure
This Plan includes the development of a multi-level parking structure accommodating approximately 1,300 vehicles."w either on the northern portion of the EOL (Area 1) or on the Main Parking Lot. It is ~,.~,;.,~ anticipated that the parking structure will be approximately four stories in height. EOL Area 1 which lies north of the Crosby gate, is the least visually sensitive location on the EOL, due to a variety of factors including the site's distance from the San Dieguito River Valley viewshed, the background structures of the Fairgrounds when viewed from I-5, the elevated height of I-5 above the site, and existing trees (and buildings) along the west side of I-5 which would provide effective screening of any structure located on the site. No conceptual plans for the parking structure have been prepared.

(See also Chapter 6, General Development Standards). 5.2.10 Horseman's Village Cafe The existing horseman's facility is inadequate to meet the needs of the Del Mar Thoroughbred Club. Conceptual plans include the demolition of the existing horseman's facility and construction of a new Horseman's Village with a cafe to serve the grooms, trainers, horse owners, and jockeys. The 25,000 sf facility would include a viewing platform adjacent to the Race Track. No preliminary design concepts for the Horseman's Village Cafe have been prepared. (See also Chapter 6, General Development Standards). 5.2.11 Vehicle Wash Rack Conceptual development plans include the construction of a second vehicle wash rack in the area west of the Racetrack also referred to as the Green Parking Lot (refer to Figure 5-1) The new vehicle rack would accommodate larger vehicles (including semi-trucks) that cannot be serviced by the primary wash rack station incorporated into the Building Area B plans (see Section 5.2.5). The new vehicle wash rack is anticipated to be equipped with a wastewater clarifier for oil and water separation and solids removal. When implemented, the new facility will become an important part of the Wastewater Treatment BMPs for the Del Mar Fairgrounds. No preliminary design concepts for the Vehicle Wash Rack have been prepared.

References to these plans include all such measures. ~z~ The timing of the second race meet relative to development of the new exhibit hall is unknown at this time. The WB triple- left mitigation measure for the Via de la Valle/Jimmy Durante Boulevard intersection is required with development of the new exhibit hall, and may or may not be completed prior to any potential second race events. Since race-event traffic control plans apply to numerous segments and intersections in the study area (e.g. I-5 NB and SB ramps at Via de la Valle, the main gate at Jimmy Durante Blvd, Solana Gate at Via de la Valle, etc), they should be implemented collectively for second race meets whether any local improvements are completed or not. /~t~['n' C Del Mar Fairgrounds Consent Order Compliance March 2013 ~ ~ ~~ ~ ~~ J and Physical Improvements Plan Page 63 CHAPTER 6 GENERAL DEVEOPMENT STANDARDS 6.1.9 Water Quality ■Any new development, temporary event, or construction activity shall be in conformance with the 22"d DAA Storm Water Management Plan and Erosion Control and Water Quality BMP Plan. ■The 22~d DAA will incorporate project -specific site design, source control, and treatment control BMPs to control predictable pollutant runoff, including an operations and maintenance plan for the prescribed structural BMPs to ensure their long-term performance. ■The 22"d DAA will further adhere to the General Industrial Storm Water Permit, NPDES Phase II permit, and incorporation of BMPs through compliance with the latest version of the City of Del Mar SUSMP requirements. ■The Storm Water Management Plan shall be kept up-to-date as required by the San Diego County Regional Water Control Board and each subsequent update shall be incorporated into this plan by reference. Temporary events and all outdoor facilities shall be subject to each subsequent revision in the same manner as the Phase II SWMP dated March 2012. To address water quality requirements of the Second Race Meet, the 22nd DAA shall implement the following improvements recommended in the Backstretch and Polytrack Water Quality Improvements Report prepared by Fuscoe Engineering, Inc., March 2013. The following improvements shall be installed in the approximate order and time frames specified. The estimated dates and time frames are assumed to commence in July 2013 but may be adjusted accordingly based on the actual year in which the initial Second Race Meet is held. ■Phase I Improvements: Backstretch Non-Horse Area Storm Drain System &Stevens Creek. The purpose of the Phase I Improvements is to reduce flooding within the CAFO Backstretch area from Stevens Creek and to collect all runoff from non-horse area impervious surfaces (i.e. rooftops) into a dedicated storm drain line. The dedicated non-horse area storm drain line would be treated by BMPs designed for sediment removal before discharging into Stevens Creek. Both of these efforts reduce the volume of water associated with the 25-year, 24-hour storm event criteria for CAFO requirements within the backstretch area. Prior to opening day of the 2015 second race meet, the following improvements will be made: 1. Prepare construction documents and obtain Resource Agency approvals for raising berm along Stevens Creek. Estimated Time Frame: 12 months. 2. Prepare construction documents and obtain local and State approvals for Backstretch Non- Horse Area Storm Drain System. Includes Horse Operation Phasing Plan to ensure safety to all horses and operators during construction period. Estimated Time Frame:8 months 3. Raise berm along Stevens Creek to a minimum elevation of 15.0'. Construct 6' retaining wall along south side of berm adjacent to Dormitory JJ. Estimated Time Frame:2 months 4. Raise berms along Infield Pond to provide additional storm water storage capacity for Polytrack and Turf Track drainage systems. The additional berms will allow multiple back-to- back storms to be retained within the Infield Ponds. No outlet from the Ponds to Stevens Creek exists and one will not be allowed as part of the project. In the event of extreme ~~~(I~ C Del Mar Fairgrounds Consent Order Compliance March 2013 ~~ J and Physical Improvements Plan Page 64 CHAPTER 6 GENERAL DEVEOPMENT STANDARDS storm events, the ponds will back up into the infield area which serves as a low-lying sump in extreme precipitation. Estimated Time Frame:3 Months 5. Install separate storm drain system to convey and treat storm water from non-horse areas of the backstretch. Estimated Time Frame:10 months. a. Add permanent roofs to structures in the backstretch that have temporary roofs. b. Add gutters and downspouts to all buildings in the backstretch that do not currently have gutters. c. Connect downspouts from all buildings to a dedicated underground storm drain system. d. For surface areas where no horses will be present, either connect the existing inlets to the new dedicated storm drain system or construct new inlets where none are present. 6. Provide storm water treatment for the water quality flow rate from these areas including sediment removal. The total estimated time duration for Phase I is 24 months (2 years) as certain components can be done concurrently. ■Phase 11 Improvements: Storm Water Disinfection System Infrastructure & Polytrack Module. The- purpose of the Phase II improvements is to collect stormwater from the Polytrack, Turf Track and Infield drainage area, temporarily store within the infield ponds and then pump through a storm water disinfection system prior to discharging into Stevens Creek. The disinfection system includes gross solids removal, particulate filtration, ozone enhanced foam floatation and UV sterilization. Prior to opening day of the 2018 second race meet: 1. Prepare construction drawings for the Storm Water Disinfection System including storm drain, sewer, disinfection infrastructure and polytrack treatment module. Estimated Time Frame: 12 months 2. Obtain Resource Agency Permits for Waste Discharge Requirements for Disinfection System (UV Primary Disinfection Component). Estimated Time Frame:8 months 3. Construction disinfection system at near the westerly portion of the property adjacent to Stevens Creek. Approximate dimensions of the treatment plant are 68' by 46', with a maximum height of 24'. Estimated Time Frame: 10 months 4. Direct runoff from the Polytrack, Turf Track and Infield to the lakes for storage. Estimated Time Frame:2 months 5. Direct runoff from the Infield Ponds through the disinfection system prior to discharging into Stevens Creek at the existing outlet location. Estimated Time Frame:4 months The total estimated time duration for Phase II is 30 months(2 %years) as certain components can be done concurrently. /~t~('A' C Del Mar Fairgrounds Consent Order Compliance March 2013 ~ ~ ~~ ~ r J and Physical Improvements Plan Page 65 CHAPTER 6 GENERAL DEVEOPMENT STANDARDS ■Phase III Improvements: Storm Water /Wash Water Connection System and Backstretch Disinfection Module. The purpose of the Phase III improvements is to collect storm water from the horse areas of the backstretch, temporarily store within the infield ponds and then pump through a storm water disinfection system prior to discharging into Stevens Creek. The disinfection system includes gross solids removal, particulate filtration, ozone enhanced foam floatation and UV sterilization. The draw down process also allows future rain events to be diverted to the Infield ponds. Due to the similarities in water quality characteristics with storm water, horse wash waters during non-rainy times will also be collected and discharged into the Infield Ponds for treatment. Currently, all horse wash water and initial flows of storm events are sent to the sanitary sewer. The proposed system would alleviate significant volumes of horse wash water and storm water from entering the sewer system thereby maintaining capacity for more traditional uses. Prior to opening day of the 2019 second race meet. 1. Prepare construction drawings for the wash water/storm drain collection system to convey CAFO runoff and horse wash water from the backstretch area to the Infield Ponds for storage. Estimated Time Frame:6 months 2. Prepare construction drawings for Backstretch and Wash Water Disinfection Component to be added to the existing disinfection system. Estimated Time Frame:6 months 3. Construct a wash water/storm drain system to convey horse wash water and runoff from horse areas of the Backstretch to the Infield lakes for storage. Estimated Time Frame: 6 months 4. Expand disinfection system by adding Backstretch Treatment Module to accommodate backstretch storm water and horse wash water. Estimated Time Frame:6 months 5. Direct runoff from the Infield Ponds (now collecting from Polytrack, Turf Track, Infield, Backstretch and Wash Water systems) through the disinfection system prior to discharge into Stevens Creek at the existing outlet. Estimated Time Frame:4 months The total estimated time duration for Phase III is 18 months(1 %years) as certain components can be done concurrently. ■Optionalltem 1. Prepare construction drawings for a loes-flow diversion system for Stevens Creek to provide disinfection of urban runoff during dry season and low flows during wet season events. Obtain Resource Agency approvals for low-flow diversions during dry and wet weather months. Estimated Time Frame: 12 months 2. Construct low-flow diversion system for Stevens Creek to divert urban runoff and initial wet season flows from Stevens Creek into the disinfection systems for regional bacteria reduction to assist with Bacterial TMDL compliance. Estimated Time Frame:4 months The total estimated time duration for the optional Stevens Creek diversion system is 16 months. n~~('A' S Del Mar Fairgrounds Consent Order Compliance March 2013 ~ ~ ~~ ~ ~~ and Physical Improvements Plan Page 66 CHAPTER 6 GENERAL DEVEOPMENT STANDARDS ■Assumptions and Clarifications 1. All time frames are estimated based on past experience and best judgment. In the event approvals from the Resource Agencies take longer than estimated, completion dates will be extended beyond estimated time frames by equivalent amounts. 2. The 22"d DAA may reduce the required disinfection treatment volumes by the construction of a separate Infield drainage system that is treated separately and bypasses the proposed disinfection system. 3. The 22°d DAA reserves the right to reduce the treatment volumes for non-CAFO areas (i.e. Polytrack and Turf Track) if the system incorporates the low-flow diversion for Stevens Creek for dry season urban runoff and wet season storm flows. n~K'~ C Del Mar Fairgrounds Consent Order Compliance March 2013 ~ ~ J and Physical Improvements Plan Page 67 CHAPTER 6 GENERAL DEVEOPMENT STANDARDS This page intentionally left blank. ^~~(I A'C Del Mar Fairgrounds Consent Order Compliance March 2013 ~ ~ ~~ ~ ~~J and Physical Improvements Plan Page 68
