SECTION 1:
INTRODUCTION The Lower Arroyo Master Plan was adopted by thePasadena City Council in 1995 and has currently been updated. TheArroyo Seco, a major tributary to the Los Angeles River, flows outof the San Gabriel Mountains in the northwest corner of the City ofPasadena. As its waters flow through the City, the river passesthrough three distinct geographical areas: Hahamongna WatershedPark (the upper Arroyo), the Central Arroyo, and the Lower Arroyo.See Exhibit 1-1, The Arroyo Seco. The City of Pasadena is currentlydeveloping Master Plans for each area of the Arroyo Seco that lieswithin the City limits.
The Central Arroyo extends from the Colorado Bridge on the left,to the 210 Freeway, on the right. The Lower Arroyo follows theArroyo Seco from the southern boundary of the City to the ColoradoStreet Bridge near the 134 Ventura Freeway. The Lower Arroyo MasterPlan was adopted by the Pasadena City Council in 1995 and iscurrently being updated. The Hahamongna Watershed Park Master Planwas conceptually approved by the City Council in November, 1999.Hahamongna Watershed Park extends from the 210 Freeway north, pastthe Jet Propulsion Laboratory (JPL) bridge, to its upper watershed.This document is the Central Arroyo Master Plan. The area coveredunder this Master Plan extends north from the Colorado StreetBridge to the 210 Freeway. On completion of all three master plans,a Master Environmental Impact Report (MEIR) for the entire ArroyoSeco will be undertaken. The Central Arroyo is located in Township1 North, Range 12 West on the Pasadena, California 7.5’ USGSquadrangle map. The Central Arroyo is generally bounded by ArroyoBoulevard and Arroyo Terrace on the east and Linda Vista Avenue onthe west. The neighborhoods to the east and west areresidential.

As early as 1887, the citizens of Pasadena recognized that theland surrounding the Arroyo Seco should become a park for theenjoyment and benefit of the public. The City of Pasadenaaccumulated the land for what is now the Central and Lower Arroyobetween 1911 and 1927. In 1918, the Arroyo Park Committee headed byarchitect Myron Hunt recommended that a comprehensive plan bedeveloped by noted landscape architect Emile Mische. This planrecommended that the Lower Arroyo be reserved for trails and bridlepaths and that the Central Arroyo (then known as the Upper Arroyo)be dedicated to recreation. By 1913, the City had begun toconstruct a children’s playground, picnic areas, and sports fieldsin the Central Arroyo. In 1914, Mrs. E. W. Brook donated the fundsto build the first public pool in Pasadena. The Brookside Plungewas constructed in what became known as Brookside Park in honor ofMrs. Brook. Tennis courts and a baseball field were added to thepark and in 1924 the stone amphitheater was built. In 1922, theRose Bowl was constructed just north of Brookside Park when itbecame evident that the annual Tournament of Roses football gamehad outgrown Tournament Park at California Avenue and WilsonAvenue. Architect Myron Hunt originally designed the stadium in anopen horseshoe design to seat 57,000. In 1931, the stadium wasexpanded to accommodate 86,000 fans. Hunt’s design, which placedthe Bowl on the flood plain of the Arroyo, had the effect ofminimizing its height and visual impact on the surrounding park.The Brookside Golf Club features two 18-hole golf courses. The C.W. Koiner course was opened in 1928 and is acknowledged to besomewhat more difficult than the E.O. Nay course, which opened in1952. Noted golf course designer Billy Bell designed both courses.The clubhouse was originally designed by Myron Hunt and HaroldChambers. In 1928, when the Municipal Golf Course was finished, theoutline of the existing facilities seen today was in place. Themajor physical elements of the Central Arroyo are identified in thefollowing Exhibit 1-2, Study Area. 1.1 RELATIONSHIP TO OTHER PLANSThe General Plan The second guiding principle of the City ofPasadena’s Comprehensive General Plan states that “change will beharmonized to preserve Pasadena’s historic character andenvironment.” Pursuant to this guiding principle, Objective 9, OpenSpace Preservation and Acquisition, specifically identifies theArroyo Seco for preservation. Policy 9.2 further states “continueand complete comprehensive planning for, and implementation of,plans for the Arroyo, including restoration of the natural area ofthe Lower Arroyo and the development of the Hahamongna WatershedPark Plan.”

The Arroyo Seco Ordinance The Ordinance, as part of the PasadenaMunicipal Code (Chapter 3, Section 32), identifies the uses,activities, facilities, and structures permitted on the publiclands of the Arroyo Seco as well as their limitations. The ArroyoSeco is defined as those public lands lying within the areagenerally bounded by Devil’s Gate Dam on the north, Linda VistaAvenue, San Rafael Avenue, and Hillside Terrace on the west, thecity limits on the south, and Arroyo Boulevard, Arroyo Terrace,Scott Place, Prospect Boulevard, and Armada Drive on the east. Thisarea includes the Central Arroyo and the Lower Arroyo. It does notinclude Hahamongna Watershed Park. The Ordinance identifiessub-areas within the Arroyo Seco for the application of certainregulations. The identified sub-areas include: Natural Preservationarea, Brookside Park area, Rose Bowl area, and Brookside GolfCourse. The Rose Bowl area is defined as the stadium and adjoiningparking lots B, D, F, G, J and K. The maximum number of Rose Bowl“displacement” events under the Arroyo Ordinance is 12 events on anannual basis. A displacement event is one that is projected to havemore than 20,000 in attendance. On August 13, 2001, the PasadenaCity Council conceptually approved the Rose Bowl Operating CompanyUse Plan, which permits a maximum of 25 scheduled events. Centuryof Bikes, Pasadena Bicycle Master Plan The Pasadena Bicycle MasterPlan was published in April 2000, and adopted in 2001, by the Cityto create a safe and attractive environment that will promotebicycling as a transportation mode. The Bicycle Master Planidentifies a grid of east-west and north-south streets to be madebicycle-friendly through a variety of recommended methods. ThisMaster Plan for the Central Arroyo Seco expands upon therecommendations contained in the General Plan and provides guidancefor meeting Pasadena’s goal of becoming “bicycle friendly.” 1.2PROJECT HISTORY The Central Arroyo Master Plan (Master Plan) reportis a product of an analysis of existing conditions; a review ofpertinent documents; input from City officials, the Central ArroyoMaster Plan Advisory Committee (CAMPAC) and City staff; andcomments from the community through an extensive outreach program.In November of 1999, the Recreation and Parks Commissionestablished the Central Arroyo Master Plan Advisory Committee(CAMPAC) to oversee the Master Plan process. Members of theAdvisory Committee included representatives from the Rose BowlOperating Company, Brookside Golf Course, the Tournament of RosesAssociation, the Rose Bowl Aquatics Center, the Pasadena Parks andRecreation Commission, neighboring homeowner associations, and twoCity-wide, at-large representatives.

SECTION 2:
EXISTING CONDITIONS 2.1 OWNERSHIP, ZONING, EAsem*nTS Apredominance of the land in the Central Arroyo is in publicownership. There is however, a small percentage of hillside areathat is in private ownership for residential purposes; this isfound primarily on the westside of the Central Arroyo. The area iszoned and given the land use designation of “Open Space” by theCity of Pasadena General Plan. “Open Space” is defined by thePasadena General Plan as follows: “This category is for a varietyof active and passive public recreational facilities and forCity-owned open space facilities. This includes natural open spacesand areas which have been designated as environmentally andecologically significant. This category also applies to land whichis publicly owned, though in some instances public access may berestricted. Most importantly, this designation only applies tolands owned by the City.” The neighborhoods adjacent to the CentralArroyo are primarily zoned single-family residential in thehillside development district (RS4 HD or RS2 HD). On the southeastedge along Arroyo Terrace are small areas zoned multi-familyresidential (RM 16). The Los Angeles County Department of PublicWorks (the County) has an easem*nt for the flood control channelthat bisects the park. The Metropolitan Water District has aneasem*nt that crosses the Central Arroyo parallel to Seco Street.2.2 LOS ANGELES COUNTY FLOOD CONTROL CHANNEL The Devil’s Gate Damcontrols the drainage from the upper Arroyo Seco watershed andHahamongna Watershed Park into the flood control channel of theCentral Arroyo. The waters released from Devil’s Gate Dam initiallyflow through the existing natural streambed just below the dam, andthen through an open trapezoidal concrete channel extending fromthe golf course to north of Seco Street. South of Seco Street thewater is carried by an open rectangular concrete channel, extending750 feet south to the natural drainage channel under the HollyStreet Bridge, the Colorado Street Bridge, and into the LowerArroyo. The County flood-control channel bisects the CentralArroyo, blocking functional access throughout the park. The presentconfiguration of the channel with its chain-link fencing isunaesthetic as well as below capacity for major storm events.

CITY OF PASADENA / ARROYO SECO MASTER PLANS Central ArroyoMaster Plan
Interest in restoring the natural Arroyo Seco streamcourse hasbeen expressed by individual community members and certainorganizations. A feasibility study has been conducted by the ArroyoSeco Foundation and North East Trees to identify opportunities forstream restoration in the Arroyo Seco. The County has indicated adesire to study possible solutions to increase the flood controlcapacity of the channel. Improvement strategies identified includethe following options: 1. A partial or completely covered channel2. A covered channel with low-flow stream at feasible locations 3.A naturalized stream course at feasible locations 4. An improvedopen concrete channel All of these options will continue to beaggressively pursued with the County and the U.S. Army Corps ofEngineers and considered in any future feasibility studiesundertaken by these agencies. 2.3 UTILITIES Water Mains To servicethe many recreation facilities in the Central Arroyo, a network ofwater mains covers most of the flat terrain. See following Exhibit2-1, Water Lines. Storm Drains The Arroyo Seco is the primarydrainage channel for western Pasadena. A number of storm drainsserving the residential streets connect directly into the floodcontrol channel. The roadways and parking lots within the CentralArroyo also drain directly into the channel. See Exhibit 2-2, StormDrains. Community comment indicated that trash removal from thestorm drains is an issue. The storm drain inlet at the golf course(along Rosemont) is currently undersized for the amount of runofffrom the surrounding slopes. Flooding associated with this drainprimarily impacts the golf course. No funding is currentlyavailable for this project. The two main storm drains in thevicinity of the Rose Bowl have recently been modernized. However,the remainder of the Rose Bowl drainage system does not meetcurrent needs. Most catch basins have restricted inlets, haveruptured, or are rotted. Many of the corrugated metal pipes aroundthe Rose Bowl have collapsed and City engineers cannot confirm thelocation of many older lines. The Rose Bowl Operating Company(RBOC) is currently working to remedy these conditions. North ofWashington Street and west of the flood channel, there are sectionsof 42″ pipe that extend partially down the slope, emptying into thechannel. The City maintains some of these old storm drains thatempty into the channel from the Linda Vista Area.

There are some storm drains that are not owned by the City alongboth sides of the Arroyo Seco that were built before the floodcontrol channel; they are not directly connected to the channel andcontinue to drain into the canyon. There are also a number ofCounty-maintained as well as private, storm drains. The City wouldlike to take over the private drains and have control of theirmaintenance, but lacks the funding. Brookside Park has a number ofcollapsed storm drains in several of the picnic areas behind theAquatic Center that obviously need reconstruction, as indicated bysink holes that are created during storms.

Sewer Lines Sewer lines primarily serve the southeastern sectionof the Central Arroyo where most of the structures have beenlocated. See Exhibit 2-3, Sewer lines. There are no known sewerlines in the golf course other than the line that services theClubhouse. Between the pump station on Rosemont, just north ofWashington and the Clubhouse, there is no existing sewer line. Allsewers lead to the County outfall in South Pasadena. The Rosemontpump station is obsolete and could be removed. It currentlyservices about 40 homes. The City Engineer recommends theinstallation of a gravity-fed sewer line connecting south to theBrookside Clubhouse. Any proposals requiring service on the westside of the golf course will require temporary chemical toilets ora pump station upslope to the Linda Vista line. This line iscurrently being repaired and planned to be turned over to LosAngeles County Sanitation District. No septic systems have beenbuilt in the City in recent history. Septic systems are generallydiscouraged, unless sewer service is not available.

Access via SR 134 is providedvia a diamond interchange at San Rafael Avenue, and freeway rampsat Holly Street/Orange Grove Boulevard and Colorado Avenue/OrangeGrove Boulevard. Additional regional access is provided via theGlendale Freeway (SR 2) located west of the Central Arroyo. Forspecial Rose Bowl events, temporary changeable message signs areprovided by the California Department of Transportation (Caltrans)along the 134 and 210 freeways. It should be noted that additionalregional access will be provided in the vicinity of the CentralArroyo with the construction of the Pasadena Gold Line light-railproject. The Blue line, combined with the existing shuttle system,will provide additional opportunities to reduce car trips in theCentral Arroyo at major Rose Bowl events. Stations are planned atDel Mar Boulevard and Holly Street. The Del Mar station will haveapproximately 600 parking spaces, which might be available foroffsite parking during events. An additional 1,000 parking spacesare available at Sierra Madre Villa Avenue. It is anticipated thatthis additional parking can serve event parking demands as well.Local access to the Central Arroyo is provided by Rosemont Avenue,West Washington Drive, Rose Bowl Drive, Seco Street, ArroyoBoulevard, Salvia Canyon Road, and Parkview Avenue. Each of theseimportant local roads is briefly described below. Existingpermanent signs are provided to guide motorists into and away fromthe Rose Bowl at key locations in the vicinity. It should be notedthat these roads provide continuous access to and through theCentral Arroyo. Other than a sharply descending roadway and theopen vistas of the flat bottom land there is no indication ofarrival into the Central Arroyo. Rosemont Avenue is a two-lane,north-south roadway that parallels the eastern edge of the CentralArroyo. It extends from Arroyo Boulevard on the north to OrangeGrove Boulevard on the south. During special events, between SecoStreet and Orange Grove Boulevard, it is converted to two lanesinbound during the event arrival period and two lanes outboundduring the event departure period. Between Orange Grove Boulevardand Seco Street, Rosemont Avenue is posted with a 25 miles per hour(mph) speed limit; north of Seco Street it is posted with a 35 mphspeed limit. Near the Brookside Golf Course, two-hour parallelparking is provided on the eastside. West Drive is a two-lane,north-south road that borders the western edge of the Rose Bowl andBrookside Golf Course. During special events an additional inboundand outbound lane is provided with the use of traffic controlcones. West Drive is posted with a 40 mph speed limit. Parking ispermitted on the shoulder of the west side of the street, oppositethe Golf Course.

2.5 EXISTING LOCAL PUBLIC TRANSIT SERVICES The Central Arroyo isserved directly by a bus line operated by the Los Angeles CountyMetropolitan Transportation Authority (MTA) and indirectly by thePasadena Area Rapid Transit Service (ARTS). MTA Line 177 is theonly transit route that passes through the Central Arroyo. The MTA177 provides service to and from downtown Glendale via GlendaleCollege, through Montrose, La Canada-Flintridge, Pasadena, and tothe City of Hope in Duarte. The line follows Linda Vista Avenue,Seco Street, Lincoln Avenue, and Orange Grove Boulevard in thevicinity of the Central Arroyo. Approximately seven bus routes havetransfer opportunities to MTA 177. ARTS Route 20 operates on theeast side of the Central Arroyo along Fair Oaks Avenue betweenOrange Grove Boulevard and Woodbury Road. ARTS Route 31/32 operateson the east side of the Central Arroyo southbound along Fair OaksAvenue between Woodbury Road and Washington Boulevard; it operateswestbound on Washington Boulevard between Fair Oaks Avenue andLincoln Avenue, and northbound on Lincoln Avenue to Woodbury Road.ARTS Route 50 operates on both the east and west side of theCentral Arroyo. On the eastside, Route 50 operates on MountainStreet between Fair Oaks Avenue and Seco Street. The route operateson Seco Street through the Rose Bowl area to Linda Vista Avenue,between Seco Street and as far north as the Jet PropulsionLaboratory (JPL). 2.6 LANDSCAPE AND NATURAL ENVIRONMENT The CentralArroyo has traditionally been the premier regional recreation areafor the City of Pasadena and the most developed section of theArroyo Seco. In contrast to the more natural settings of the LowerArroyo and Hahamongna Watershed Park, the Central Arroyo has alwaysaccommodated the broad turf areas necessary for active recreationand landscaping that has year-round appeal and lushness. Theprominence of the landscape is in part due to the siting of theRose Bowl on the canyon floor, de-emphasizing its height and mass.The wooded slopes rather than the stadium are still the mostdistinctive feature of the Central Arroyo, creating a world apartfrom the City’s urban environment. At either end, as the CentralArroyo narrows, the park landscape transitions to a naturalsetting. The surrounding hillsides look onto the two view corridorsin the Central Arroyo. The view corridor to the north includesviews to the Rose Bowl stadium, Brookside Golf Course, and the SanGabriel Mountains. The southern view corridor includes views to theLower Arroyo, Colorado Street Bridge, and the Holly StreetBridge.

CITY OF PASADENA / ARROYO SECO MASTER PLANS Central ArroyoMaster Plan
The plant communities, vegetation, and wildlife of the CentralArroyo probably would not exist in their current array withouthuman influence. The altered and unnatural environmental conditionscurrently found there are due mainly to three factors. These are:(1) The presence of Devil’s Gate Dam; (2) the development ofinfrastructure for public works and recreation; and (3) the earlieragricultural and landscaping practices that over time havesignificantly changed the appearance and composition of the CentralArroyo and nearby areas from that once familiar to the NativeAmerican Gabrielinos. Field inventory surveys of biologicalresources in Central Arroyo were conducted over an area extendingfrom the 210 Freeway just south of the Devil’s Gate Dam to theColorado Street Bridge. The inventories also included theidentification of existing terrestrial natural plant communitiesand landscaped and ruderal vegetation in the park. Additionally,field surveys were conducted in the park to determine the status ofany potentially occurring wetlands and other waters of the UnitedStates that may fall under the jurisdiction of the U.S. Army Corpsof Engineers (COE) and/or the California Department of Fish andGame (CDFG). A total of 278 plant species and 89 animal specieswere observed during the inventory surveys. For an urban park thesenumbers demonstrate a relatively high biodiversity. See BiologicalReport1 in the Technical Appendices of this Master Plan for aninventory of existing plants and animals observed. Five terrestrialnatural plant communities were recorded and mapped in the park.These included coast live oak woodland, southern willow scrub, mulefat scrub, sage scrub, and southern sycamore riparian woodland.Several categories of vegetation, which do not fit the usualdefinitions as terrestrial natural communities were also recordedand mapped. These categories included ruderal and landscapedvegetation. Other features that were mapped included developedareas that are composed of infrastructure features such as roads,buildings, parking lots, or the concrete storm channel that werenot vegetated. See Exhibit 2-5, Terrestrial Natural PlantCommunities. Plant Communities In the survey areas, 75% of thepark, or 409 acres out of a total 545 acres, is developed orconsists of landscape vegetation. Approximately 136 acres consistof a mixture of the five native terrestrial natural plantcommunities: (1) Coast live oak woodland; (2) Sage scrub; (3) Mulefat scrub; (4) Southern willow scrub; and (5) California sycamorewoodland as defined by Holland (1986)2 and Sawyer and Keeler-Woolf(1995).3 These communities are restricted to the slopes of theCentral Arroyo and the areas directly below Devil’s Gate Dam 1Biological Technical Report: Inventory Surveys of BiologicalResources at Central Arroyo Seco Park.

Coast Live Oak Woodland Coast live oak woodland is typicallylocated on north-facing slopes and shaded ravines in southernCalifornia. In the Central Arroyo Seco, it occurs in discontinuousareas on side slopes along the west and east boundaries of thepark. There it intergrades with sage scrub, southern sycamoreriparian woodland, southern willow scrub, and ruderal vegetation.There are still certain areas where a remnant example of coast liveoak (Quercus agrifolia var. agrifolia) is co-dominant with toyon orchristmas berry (Heteromeles arbutifolia), and/or with southernCalifornia black walnut (Juglans californica var. californica).Sawyer and Keeler-Wolf (1995) refer to coast live oak woodland ascoast live oak series. Generally, coast live oak woodlands inhabitupland areas on slopes that are often very steep, or on raisedstream banks and terraces. Soils are well drained, and are oftensandstone or shale-derived but may also be granitic in composition.Coast live oak may be the sole or dominant tree in the canopy.These oaks reach heights as great as 100 feet (30 meters), and thecanopy may be continuous, intermittent, or open. Shrubs areoccasional or sometimes common in the understory and the groundsurface layer is grassy or absent. Commonly associated shrubunderstory species in this plant community include black sage(Salvia mellifera), California blackberry (Rubus ursinus),California bay or laurel (Umbellularia californica), Californiaredberry (Rhamnus californica), California sagebrush (Artemisiacalifornica), chamise (Adenostoma fasciculatum), laurel sumac(Malosma laurina), western poison oak (Toxicodendron diversilobum),scrub oak (Quercus berberidifolia), toyon, Mexican elderberry(Sambucus mexicana), bigleaf maple (Acer macrophyllum), box elder(A. negundo), hairy ceanothus (Ceanothus oliganthus), Engelmann oak(Quercus engelmannii), bush monkeyflower (Mimulus aurantiacus), andvarious currant or gooseberry species (Ribes spp.). The herbaceouslayer component is often continuous and dominated by ripgut (Bromusdiandrus) and other introduced species such as common chickweed(Stellaria media). Coast live oak woodland habitat is notconsidered sensitive by the State of California. Forest habitats,in contrast, connote a greater density of trees than to woodlands.Trees growing close enough that their canopies often touch and thatcollectively cover more than 60 percent of the ground characterizeforest habitat. Woodland canopies cover 30 to 60 percent of theground. Sawyer and Keeler-Wolf (1995) note that coast live oak isnot listed on the national inventory of wetland plants by Reed(1988). Coast live oak woodland is valuable habitat that supports awide variety of wildlife species. Southern Willow Scrub Southernwillow scrub dominates the southern reaches of the park near the134 Freeway and the Colorado Street Bridge where the ripariancorridor of the Arroyo Seco drainage regains a more naturalappearance south of the terminus of the concrete storm waterchannel. At this area of the Central Arroyo, it merges with sagescrub, ruderal vegetation, coast live oak

woodland, and the landscaped vegetation of the adjacentresidents. The southern willow scrub in the southern part of theCentral Arroyo is also widely mixed with other introduced andnaturalized tree species, such as eucalyptus (Eucalyptus spp.),date and fan palms (Phoenix canariensis and Washingtonia robusta),and pines (Pinus spp.) among others. Southern willow scrub is anearly seral or successional type that requires repeated flooding toprevent succession to southern cottonwood-sycamore riparian forest.This plant community is comprised of dense, broad-leaved,winter-deciduous riparian thickets dominated by several willowspecies including arroyo willow (Salix lasiolepis), black willow(S. gooddingii), red willow (S. larvigata), shining willow (S.lucida ssp. lasiandra), and narrow-leaved willow (S. exigua). Thisriparian scrub community occupies sites with loose sandy or finegravelly alluvium deposited along intermittent or perennial streamchannels during flood flows. Habitats within this community areusually seasonally flooded and the soils saturated. Southern willowscrub typically occupies sites on flood plains, or in low gradientdepositions along streams. Shrubs and trees in this community mayreach between 33 to 100 feet in height, and the canopy may becontinuous. Most stands often are so dense that the understoryvegetation layer of grasses and forbs may vary from sparse toabundant. Also associated with this riparian scrub community arescattered emergent species of Fremont cottonwood (Populus fremontiissp. Fremontii)), black cottonwood (P. balsamifera ssp. trichocarpa), and western sycamore (Platanus racemosa). Other commonlyassociated species include mule fat (Baccharis salicifolia), coyotebrush (B. pilularis), mugwort (Artemesia douglasiana), Mexicanelderberry, and bigleaf maple. The Army Corps of Engineers and U.S.Fish and Wildlife Service (USFWS) definition and classification ofwetlands employs hydric soils, saturation or inundation, andvegetation criteria and requires the presence of all three criteriain order to classify an area as a wetland. Southern willow scrub isone of three natural plant communities within the Central Arroyothat are composed of vegetation that typify riparian habitats, someof which include wetland indicator species that may also be foundin wetland habitats. Wetlands and riparian habitats are on thedecline around the nation and are considered sensitive vegetationtypes that warrant considerable regulatory agency oversightregarding their development. Southern willow scrub in the CentralArroyo is comprised of well-established, native wetland habitatsthat are important for wildlife. This plant community is worthy ofapplied conservation efforts. Mule Fat Scrub Mule fat scrub occursin restricted areas along the riparian stream corridor of theArroyo Seco drainage, just south of the southern sycamore riparianwoodland at the north end of the Central Arroyo and just north ofthe concrete storm water channel. The plant community is quitesmall and is bordered by landscaped vegetation, southern sycamoreriparian woodland and coast live oak woodland. Mule fat scrub is anearly seral community that is maintained by frequent flooding. Whensuch flooding conditions are absent, mule fat scrub stands wouldsucceed to cottonwood or sycamore-dominated riparian forests orwoodland. Periodic releases of accumulated rainwater runoffcollected behind Devil’s Gate Dam may help to

maintain this isolated community in this area of the CentralArroyo. Mule fat scrub is typically characterized by tall,herbaceous riparian scrub species dominated by Baccharissalicifolia. Mule fat is usually the sole or dominant shrub in thecanopy, along with narrow-leaved willow, and the plants may attainheights of 13 feet. The canopy often is continuous and the groundlayer of vegetation is sparse. This terrestrial natural communityis located along intermittent stream channels with fairly coarsesubstrate and moderate depth to the water table. Habitats withinthis community are also seasonally flooded and the ground issaturated. Other commonly associated species in mule fat scrubinclude arroyo willow, narrow-leaved willow, hoary nettle (Urticadioica ssp. holosericea), Mexican elderberry, and sedges (Carexspp.). Sage Scrub Sage scrub is found on slopes and sidewalls ofthe Arroyo Seco drainage. It also blends as indistinct borders withcoast live oak woodland and ruderal/landscaped vegetation indeveloped areas of the Central Arroyo. Sage scrub is a mixture offire-adapted, sclerophyllous (hard-leaved), woody chaparralspecies, and drought-deciduous sage scrub species. This plantcommunity appears to be post-fire successional and is found on dry,rocky, often steep, south-facing slopes and ridges with shallow orpoorly differentiated soils. Often these soils are derived fromrock detritus and soil accumulated at the foot of a slope. Thisplant community may also be located on clay-rich soils that areslow to release stored water and that favor the proliferation ofCalifornia sagebrush over chamise. Generally, shrubs in coastalsage-chaparral scrub are no more than six to ten feet in height,although in some areas with associated emergent shrub or treespecies, the plants may attain heights up to13 feet (four meters).The canopy is continuous or intermittent, and the ground layer issparse or absent. Understory cover of forbs and grasses is oftenvariable depending upon the fire history of a particular site.Sawyer and Keeler-Wolf (1995) believe that coastal sage-chaparralscrub is a mixed combination of California sagebrush-Californiabuckwheat series, California sagebrush-black sage series,chamise-black sage series, and sumac series. Dominant species inthis terrestrial natural community include California sagebrush,chamise, California buckwheat, black sage, white sage, laurelsumac, lemonadeberry, sugar bush, deerweed, chaparral yucca, bushmonkeyflower, hoaryleaf ceanothus (Ceanothus crassifolius), otherceanothus or California-lilac species (Ceanothus spp.), scrub oak,birch-leaf mountain-mahogany, poison oak, holly-leaf cherry (Prunusilicifolia ssp. ilicifolia), southern California walnut, Californiaencelia, Mexican elderberry, toyon, Brazilian pepper (Schinusterebinthifolius), and Peruvian pepper (S. molle).

Southern Sycamore Riparian Woodland Southern sycamore riparianwoodland is very limited in its distribution within the CentralArroyo boundaries. Currently, it is found bordering the naturalstream channel just south of Devil’s Gate Dam and the 210 Freewaybefore the start of the flood control channel. Here, surface flowsof water that run past the dam help sustain the hydrologic regimeneeded by western sycamore trees. Holland’s (1986) vegetationclassification system has no “southern sycamore riparian woodland,”but this report utilizes the descriptions given to southernsycamore-alder riparian woodland. Western sycamore is frequentlyutilized as a landscape tree on properties in surroundingresidential and other urban areas. Southern sycamore-alder riparianwoodland is a tall [

The State considers southern sycamore-alder woodland to be asensitive habitat (CNDDB, 1999a and f).4 Landscaped VegetationLandscaped vegetation is largely composed of cultivated ornamental,horticultural plants that may be introduced or native tree, shrub,forb, and grass species. Landscaped vegetation plant species areusually aesthetically appealing and are moderately to extremelydependent on humans for water, minerals and nutrients (fromfertilizers and soil amendments), pruning and maintenance, pest andpathogen control, and for their establishment in an environmentalsetting. That setting often is urban infrastructure, such asbuildings, roads, parking areas, walls, developed parkland,man-made lakes, and ponds. Many of the plant species that compriselandscaped vegetation are drought-tolerant xerophytes that requirelittle or no irrigation for their survival. Occasionally,landscaped plants establish themselves outside of their intendedsetting and become established in the wild. Landscaped plants canbecome naturalized by virtue of adaptive dispersal mechanisms andstrategies of their fruits, seeds, root systems, vegetativereproduction from plant parts, and animal transport. Ruderal, weedyplants are often annuals or biennials and, therefore, reproducerapidly and successfully in places and conditions that other nativeor introduced perennial plants cannot. In the Central Arroyo, thesoil types and textures on the various survey sites of landscapedvegetation are characterized as urban land that historicallyconsisted of native alluvial soils comprised of dry, dense, siltyand occasionally gravelly sand, rocks and boulders. Several feet ofintroduced fill material of unknown origin and varying compositionmay cover the site. The Central Arroyo was once used as a dumpingground. This vegetation category was not surveyed to the extent anddepth as other native, natural terrestrial plant communities duringthe recent inventory surveys of biological resources. However, thisunnatural plant community type was mapped on the naturalterrestrial plant community map. The numbers and types oflandscaped vegetation are too numerous and diverse to include inthe scope of work for this project. Common landscape plantsobserved in the Park included species of eucalyptus, pine, oak,acacia, western sycamore, fig, olive, pittosporum, cherry, peppertree, maple, liquidambar, ash, juniper, cypress, pyracantha,walnut, hibiscus, oleander, privet, redwood, elm, palm, coral tree,periwinkle, lantana, ivy, plumbago, poplar, tree of heaven, agave,and many others.

The Landscaped Setting Today, the asphalt parking areas thatsurround the Rose Bowl are striking when seen in an aerial view orfrom above along the canyon edge. Many of the trees that werepreserved when the parking lots were constructed have since diedand have not been replaced. There are no landscaped islands tobreak up the expanse of asphalt due, in part, to the need forflexibility in staging special events. The storm water runoff fromthese impervious surfaces flows directly into the flood channelwithout treatment. Green swales that retain or slow runoff to meetwater quality standards could be incorporated into the perimetersof the parking areas. Funding to maintain the park areas of theCentral Arroyo has been reduced while use of the facilities hasgrown. User groups and the community have expressed their desirefor improved maintenance within the Central Arroyo. 2.7 ROSE BOWLSTADIUM The 93,000-seat Rose Bowl Stadium, the largest structure inthe Arroyo Seco, has hosted the Rose Bowl football game for 75years. The original horseshoe structure was finished in 1923 andhas undergone remodeling several times to increase the seatingcapacity. The Rose Bowl is managed by the Rose Bowl OperatingCompany (RBOC) as a California nonprofit corporation for thebenefit of the public. A double-lane road with a rose garden in themedian serves as an entry to the stadium. The entry is known as theCourt of Champions and serves as both the main public entry and theprimary service entrance for the Rose Bowl.

An unused horseshoe pit and a few remaining piecesof a large, heavy-timber play structure are left over from earlierpark developments. The park also features the Fannie MorrisonCenter (soon to be the new home of the Kidspace Children’s Museum),the Rosemont Pavilion, group picnic facilities, and otherpark-related elements. There are four restrooms and a storagestructure. General parking is available in Parking Area I. RoseBowl Aquatics Center The Rose Bowl Aquatic Center’s (RBAC) missionis to provide state-of-the-art aquatic opportunities to allregardless of ability to pay. Two Olympic-standard pools areavailable for recreation and competitive swimming. Future plansinclude the construction of a heated therapy and teaching pool andan exercise/weight room. Programs and scholarship opportunities areavailable to young and old, the fit and disabled, the recreationalswimmer, and the Olympic competitor. The pools are open year-roundwith programs continuously offered through the Pasadena UnifiedSchool District and the H2O Summer Fun Day Camp.

Jackie Robinson Baseball Stadium Jackie Robinson BaseballStadium is used by various organizations and schools, and, inrecent history, was leased by the Galaxy Soccer Team for practice.Over the course of the pre-New Year’s celebration, large gatheringsincluding the PAC 10 breakfast and corporate parties are held onthe grounds. Softball Fields Two lighted softball fields arelocated adjacent to the east side of parking area I; they areavailable to the public by reservation. These fields are used foroverflow parking during large events at the Rose Bowl. TennisCourts Five asphalt-paved tennis courts are located adjacent to theRose Bowl Aquatics Center. These courts are available to the publicby reservation. Fannie Morrison Building The Fannie MorrisonBuilding is a collection of three historic, barn-like structuressurrounding a central courtyard. Kidspace, an interactivechildren’s museum, has acquired a lease for the site and has plansto construct an 18,000 sq. ft. addition to the original 1930’sstructure. The new wing will house the permanent exhibitions and a300-seat theater. Rosemont Pavilion The Rosemont Pavilion is a33,750 sq. ft. structure on a two-acre site leased to the PasadenaTournament of Roses Association (PTRA). The Pavilion is used forfloat construction from July to January. During the Rose Bowlfestivities, the Rosemont Pavilion is used for float finishing anddisplay as part of the PTRA’s Fan Fest. The PTRA has used thisfacility for many years; its current lease expires December 31,2017. The PTRA has additional float-building facilities at the RosePalace on Raymond Street and in Azusa and Duarte. Group PicnicFacilities Six group picnic facilities are located throughout thepassive green area of the park. Most areas are defined by largeclusters of picnic tables chained together. Only one is aformalized gathering area with built-in stone barbecues. Thesefacilities are available to the public by reservation.

2.10 RECREATION LOOP From early morning to evening, the fouredge streets adjacent to the Brookside Golf Course and the RoseBowl—Seco, West, Washington, and Rosemont—operate not only as athree-mile recreation loop for bicyclists, strollers, walkers,joggers, and roller bladers but as the main vehicular circulationpattern around the Central Arroyo as well. The recreation loop ismarked by an eight-foot wide, painted pedestrian lane and signedfor a counter-clockwise direction. The pedestrian lane is adjacentto the Golf Course on the inside of the street right-of-way.Bicyclists use the interior vehicular traffic lane to circle in aclockwise direction with continuous right-hand turns. Observationshave indicated that the bicycle peloton or pack, that utilizes theloop on Tuesday and Thursday evenings during the week, averagesapproximately 30 mph. This popular activity can take up asignificant portion of the road’s right-of-way, sometimes crossingthe double yellow dividing lines into the opposing vehicular travellanes. Consequently, there exists a significant potential forconflict between the bicycle peloton and motor vehicles as well asother users of the loop. See Exhibit 2-6, Rose Bowl Loop UserGroups, 1992, for a comparison of recreational use of the Loopduring a typical weekday and during a peloton (bicycle road racers)day. There are two rest areas on the loop, the golf snack stand onWashington Avenue, and the restroom with benches/tables anddrinking fountain at the southwest corner of Area H. There areopportunities to provide improved snack and rest areas for Loopusers and golfers by expanding and reorienting the existing snackfacilities. The community has expressed the wish to createadditional shorter recreation loops. There are opportunities forshort recreation loops south of the stadium. The community also hasexpressed concern about speeding and local traffic using the parkas a short cut. Entrances and circulation through the stadiumparking areas are confusing and poorly marked. Permanent andtemporary signage has been installed for major events to helpaddress this concern.

2.11 RECREATION TRAILS AND PEDESTRIAN ACCESS The recreationtrails in the Central Arroyo are part of a regional hiking andequestrian trail system. There is also a network of localpedestrian pathways connecting to adjacent neighborhoods. RegionalHiking and Equestrian Trails Along the east and west sides of theCentral Arroyo are trails for hikers and equestrians that merge atthe northern and southern ends of the Central Arroyo. Locally,these trails are collectively known as the Arroyo Seco Trail; aspart of the regional trail system they are identified as acomponent of the Rim of the Valley Trail. The Rim of the ValleyTrail, when complete, will circle the San Fernando Valley, linkingthe Arroyo Seco to the Santa Monica Mountains. To the north throughHahamongna Watershed Park, these trails connect to the trailnetwork of the Angeles National Forest; to the south, they connectto Debs Regional Park and the Los Angeles River. See Exhibit 1-1,Arroyo Seco and Exhibit 2-7, Regional Trails below.
Exhibit 2-7, Regional Trails From the Lower Arroyo, travelingnorth, the Arroyo Seco Trail is a single path located on theshoulder of South Arroyo Boulevard adjacent to the Flood ControlChannel. After crossing Seco Street and passing through Areas F andK, the trail splits; the western segment follows the outer edge ofWest Drive north to Washington Avenue, and then the toe of theslope to the beginning of the concrete flood channel just north ofthe golf course. The trail crosses the

Equestrians and hikers following the eastern trail must picktheir way through the parking lots adjacent to the Rose Bowl toaccess the trail on the east side of Rosemont Avenue opposite theBrookside Clubhouse. The trail is located on top of the lowretaining wall along the toe of the eastern slope. The trailcrosses Rosemont Avenue north of Washington Avenue and follows theouter edge of Brookside Golf Course north to the Devil’s Gate Dam.There are two rest areas for equestrians in the Central Arroyo: (1)On the west side north of Salvia Canyon there is a hitching rail,and (2) near the Brookside Club House there is a fenced area withhitching rails and water. A tack area is provided for riders tohang up their bridles while they visit the restaurant andfacilities at the Club House. The volunteer mounted patrol alsouses this rest area to tie up during Rose Bowl events. Issues &Opportunities The equestrian crossing at Rosemont Avenue, north ofWashington Avenue, is located on a double-blind curve and theportion of the trail between the crossing and Washington Avenueleads across the face of an unstable slope. This portion of thetrail is subject to erosion and collapse. Equestrians haveidentified this section of the trail and the crossing as the areamost in need of repair in the Central Arroyo. The western trailstream crossing north of the Golf Course leads across slabs ofconcrete left from construction of the 210 Freeway. The footing isunstable with sharp drops in levels and the trail is slippery inthe winter months when water is released. Additionally, without adefined path of travel for the riders, conflicts between equestrianriders and park users occur in the parking lots surrounding theRose Bowl. In areas with a designated trail (the western route),conflicts occur when the trail is blocked by cars or booths duringRose Bowl events, in particular when the flea market is in session.Local Pedestrian Pathways Existing pathways leading into BrooksidePark from the adjacent neighborhoods include three open entries:Rosemont Avenue Entry, south of the Rosemont Pavilion, wraps aroundthe slope behind
the Fanny Morrison Building and connects to the group picnicareas behind the ball fields.
Arroyo Terrace Entry connects to the old children’s play areabehind the Aquatics Center
Holly Street Bridge Entry connects to the group picnic area atthe southern end of Parking Lot I
There are additional entries from Arroyo Terrace that have beenclosed off. With the exception of the Holly Street Bridgeconnection, the paths that lead from the above- mentioned entrieswere once part of a series of walks built by the CivilianConservation Corps during the Depression. The walks are edged witharroyo stone retaining walls that have fallen into disrepair.
2-29
CITY OF PASADENA / ARROYO SECO MASTER PLANS Central ArroyoMaster Plan
Issues & Opportunities With the exception of RosemontAvenue, south of Seco Street, pedestrians entering the CentralArroyo from local neighborhoods must walk in the street beforereaching the recreation trails or pathways of the park. Duringtimes of high traffic volume such as Rose Bowl events or rush hour,pedestrian safety is an issue. Most of the sloped areas in theCentral Arroyo are inaccessible except for the slopes adjacent toBrookside Park. Although in disrepair, the existing pathway, ifrestored, could allow park users to walk the wooded hillside underthe canopy of native oaks, sycamores, and pines. 2.12 SPECIALEVENTS IN THE CENTRAL ARROYO Within the Arroyo Seco Ordinance,under the description of the Rose Bowl area, it states that“displacement of recreation programs and activities withinBrookside Park and the Brookside Golf Course has not occurred morethan 12 times annually.” With respect to an attendance threshold,it does not provide a specific number of people attending an event,except under item F: “All proposed contracts involving the use ofthe Rose Bowl which anticipate an attendance of over 20,000 peopleshall be approved by the RBOC in conformance with this chapter…”Except in 1994, there have been no more than 14 major events in agiven year. The reason for the spiked number in 1994 (20 majorevents), were the eight World Cup matches and four concerts. 2.13SPECIAL EVENTS SHUTTLE BUS ROUTES The Rose Bowl Operating Companyoperates a Park-n-Ride shuttle during UCLA football games and someof the larger-scale special events. The free shuttle is providedunder contract by Foothill Transit. The shuttle operates betweenthe Parsons Engineering parking facilities, located on thenortheast corner of Union Street and Pasadena Avenue, and the RoseBowl. The Parsons Engineering facility provides approximately 2,300parking spaces. The shuttle buses accommodate 3,000 to 7,000persons during special events. Currently, at Parsons a parking feeof $4.00 is charged, as compared to the current Rose Bowl parkingfee of $5.00. The fee includes the free shuttle ride to the RoseBowl. Service to the Rose Bowl can begin as early as four hoursbefore the start of the event. During the peak operating hours thedeparture buses stack up along Pasadena Avenue and in two linesalong Union Street. All buses are filled to seating capacity. Thecurrent inbound route follows Pasadena Avenue north, onto the 210Freeway. The buses exit at Lincoln Avenue, turn left onto Lincoln,and proceed south to Westgate Street. At Westgate Street the busesturn right, entering the Central Arroyo from Arroyo Drive. Theinbound route takes between seven to ten minutes depending onsignal operation. This route traverses road segments with little orno traffic, including the freeway and southbound
2-30
CITY OF PASADENA / ARROYO SECO MASTER PLANS Central ArroyoMaster Plan
Lincoln Avenue. Once the buses turn right onto Westgate Street(where only local traffic is allowed during the event), thePasadena Police Department stops all cross traffic at intersectionsto allow the buses to proceed without stopping. The return routefrom the Rose Bowl retraces the inbound route to Lincoln Avenue,turning east onto Hammond Avenue, then south onto Fair Oaks Avenueto Parsons Engineering. The return route takes approximately 15minutes due to the number of turns and signalized intersections.During the event, smaller vans carry the few patrons who need toreturn before the end of the event. 2.14 PARKING Parking in theCentral Arroyo is provided in improved asphalt parking lots andselected turf areas within the Golf Course and sports fields. Theselots and areas are identified by letters. For the purposes of thisMaster Plan, please refer to Exhibit 2-9, Central Arroyo ParkingAreas. Depending on how the cars are arranged for parking,off-street parking totals range from 21,281 to 24,245 spaces.Improved asphalt parking spaces total 5,815 and parking on turfranges from 15,466 to 18,430 additional parking spaces.

The need for parking is at constant odds withthe general lack of green open space within the City andspecifically with the community’s desire to preserve the open spaceenvironment of the Central Arroyo. Parking on the turf areas,especially area H, causes compaction, poor turf recovery, and othermaintenance issues. The turf parking areas are not available forparking under wet conditions. During wet conditions, vehicles areparked on the roadways within the Central Arroyo and in adjacentneighborhoods. Recent turf management technology has producedproducts to stabilize soil for engineered turf areas, which cancope with frequent use and high loads. The system resistscompaction and rutting during wet conditions. Turf areas that havebeen constructed with this system can be parked and driven on inwet conditions. These technologies still need to be evaluated overtime and presently are quite expensive. Lease commitments with UCLAand other entities require guaranteed “all weather” parking fortheir events. Area B, the disabled parking area, could be availablefor regular parking during non-event periods. Many of the asphaltparking lots are devoid of any vegetation; they could beaesthetically enhanced with landscaping to provide shade and visualrelief.

2.15 LEASE AGREEMENTS The following groups and organizationscurrently hold leases with the City of Pasadena or with the RoseBowl Operating Company (RBOC), which acts as an agent for the City,to use the facilities in the Central Arroyo. The framework thatdefines the number of large events is the concept of “displacementevents.” These events are defined as having an attendance of 20,000people or more. Parking for this number of people “displaces” thenormal recreation activities that occur within the Central Arroyo.Term Expiration of Existing Tenants Tournament of Roses AssociationJune 30, 2019 University of California Regents (UCLA) November 30,2003 R. C. Canning Enterprises, Inc. (Flea market) May 9, 2009 RoseBowl Operating Company The Rose Bowl Operating Company (RBOC) is aCalifornia nonprofit, public benefit corporation, founded in 1995by an act of the Pasadena City Council. The purpose of the RBOC isto enhance the economic and civic value of the Rose Bowl as aworld-class stadium and the Brookside Golf Course as aprofessional-quality course. The RBOC, acting as an agent of theCity of Pasadena, leases the Rose Bowl to a number of tenants. TheRBOC is managed by an eleven-member Board of Directors. One memberis appointed by each City Council member and the Mayor. The Mayoralso nominates one member at-large from persons recommended by theother seven Council members. Members nominated by Council membersfrom Districts 1 through 6 must be residents of their district.Additionally the Tournament of Roses Association nominates a memberas does the City Manager. The Pasadena City Council maintainsoversight for RBOC funds and provides support to the RBOC forcertain operating functions. The RBOC established and oversees theRose Bowl Foundation which solicits charitable donations to benefitthe community. The RBOC employs a General Manager and a staff toadminister the Rose Bowl. Tournament of Roses Association TheAssociation is a California nonprofit corporation that stages theNew Year’s celebration known as the Tournament of Roses. Thecelebration consists of the nationally televised Rose Parade andthe Rose Bowl Game, the country’s oldest and most successfulpostseason intercollegiate football game. In order to stage theevent, the Association leases a number of facilities located withinthe Central Arroyo and throughout the City. The facilities withinthe Central Arroyo include the Rose Bowl Stadium, the adjacentparking lots and turf areas, the Rosemont Pavilion, and BrooksidePark. The Association holds two leases—one with the City ofPasadena for the facilities managed by the RBOC and one with thePasadena Parks and Natural Resources Department for Brookside Parkand Jackie Robinson Field.

Future plans include the development of a heated therapy andteaching pool for year-round physical therapy and post-surgeryprograms and progressive instruction for the very young and thedisabled. In addition, the Center plans to develop aweight-training/exercise facility to add a dimension ofcross-training to all levels of participation. University ofCalifornia Regents (UCLA) UCLA home varsity football games areplayed at the Rose Bowl during the fall season. Major events canattract 90,000 people to the Rose Bowl. Five to seven games perseason are played on Saturdays. A game can be scheduled on Sundayonly with written permission from RBOC. Practice sessions arescheduled for the Friday preceding each game, in the three weekspreceding the first home or away game (two practices sessions), andin the spring (two practice sessions). UCLA has priority over allother lessees with respect to scheduling games and practices.Between August 25 and November 30, RBOC cannot schedule events thatwould affect the quality of the turf in the Stadium. UCLA ispermitted to have a pre-paid parking program in association withthe sale and distribution of season tickets.

2.17 ARCHAEOLOGICAL RESOURCES In 1987, a Preliminary Assessmentof the Prehistoric Cultural Resources of the Devil’s GateReservoir5 (HWP) was undertaken. A record search was conducted ofarchival materials and a physical inspection of the site wasperformed. The assessment reports that “no prehistoric sites werefound to be located on the property.” The record search looked forexisting survey reports and recorded sites within the study areaand within a one-mile radius of the study area. While there were noreports or recorded sites within the study area, three sites withinthe one-mile radius were surveyed and reported. They are asfollows: Survey Area L-880: located adjacent to the study area onJPL property. This 1980 survey
concluded that there were “no known or recorded resources”within the survey area. Survey Area L-108: located southeast of theDevil’s Gate Dam between Oak Grove
Avenue and the 210 Freeway was also negative. Survey AreaL-1659: the study area, known as the La Vina property, is located.25 miles
northeast of HWP. A prehistoric quartzite flake of culturalorigin was recorded. Also within the one-mile radius there are tworecorded archaeological sites: CA-LAn-342: located .33 mile northof HWP. The site consists of part of a village,
known as the Millard Canyon site. CA-LAn-26: the SheldonReservoir site is located southeast of the Devils’ Gate Dam. In
1938, the Pasadena Water Company uncovered a burial groundduring the excavation of the reservoir.
The conclusion of the assessment was that the areas should beconsidered archaeologically sensitive given the proximity of thetwo known archaeological sites.
