INTRODUCTION 2. To provide a gathering place that will bring together people of all ages and abilities, serving the diverse need of the entire City of Dublin. The facilities should provide opportunities for tots, par- ents, teens, seniors, athletes and students of all ages, and should offer a wide variety of active and passive uses, as well as places in which to participate or observe. Purpose of the Document The following is a document of the Master Plan concepts which will guide the present and future development of Emerald Glen Park. The plan was developed while working with the Emerald Glen Park Task Force which was appointed by the City Council. During the planning process, input was solicited directly from local high schools and middle schools, Parks & Community Service Commission, City Staff, as well as the general community and user groups at workshops. 3. To develop facilities that maximize the recreational and leisure experience by creating a synergy that provides interests for all groups. The park should provide a variety of uses and sub-spaces to address the needs of both the organized league play and informal "pick-up" games; opportunities to appreciate the creek wildlife or host an evening concert; a place for kite flying, farmers' market, bike races, art shows, playgrounds and rose gardens. In developing the Emerald Glen Park Master Plan, the Task Force re- viewed the total projected recreational needs of the Dublin community, and the distribution of the required facilities in the proposed Sports Park, Community Park and Neighborhood Parks. This analysis ensures that adequate facilities and parkland will be available between Emerald Glen Park and other proposed parks to accomodate future Dublin residents' recreation needs. 4. To create a park setting that celebrates nature and reflects the uniqueness of the setting. The plan should incorporate the Tassajara Creek, existing vegetation, and major wind patterns into the final design. The historical agrarian references should be reflected, and landforms should be sculpted to create a pleasant respite from the surrounding development. The intent of this Master Plan is to lay the groundwork for park devel- opment by documenting the goals, priorities and design parameters which will govern the development of each phase. Background Overall Goals The City of Dublin is experiencing major growth in the East, which will more than double the size and population of the City within the next 20 years. It is anticipated that the majority of the new park and recreation facilities will be located in the Eastern expansion area. This growth is being directed by the Eastern Dublin Specific Plan which designates park sites to meet the future demands of the Dublin community. Four major goals were established that have influenced and guided the development of the master plan. These goals are as follows: 1. To create a strong, memorable public destination, a special place that provides a memorable and inviting focus for all of the Dublin community; a "signature park." The City of Dublin adopted a Parks and Recreation Master Plan in July, 1994. The Parks & Recreation Master Plan, which was developed concur- . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ~M[~~[D1 ~~[~ ~A~r~ rent with the Eastern Dublin Specific Plan, provides direction for address- ing the long-term recreational needs of the Dublin community and its chang- ing population through the next twenty years. The plan contains goals, long- term policies and standards to guide the City in the acquisition, develop- ment and management of park and recreation facilities. I I . CHAPTER 1: INTRODUCTION I The City Park Standards, as contained in the Parks and Recreation Mas- ter Plan, were used as a basis for directing the final design for Emerald Glen Park. The Parks & Recreation Master Plan suggests a variety of recreational opportunities that will attract a wide range of local age groups and interests. "The City Park should feature large open space areas, unique natural and cultural areas as well as group picnic areas, inter- pretive centers, bicycling and hiking trails, sports facilities, recreational facilities and other unique features or facilities.

I I I I I I I I I I I I I I I I CHAPTER 2: THE SITE. THE SITE The proposed improvements which will effect the Emerald Glen Park development include: Context Emerald Glen Park site is located near major transportation corridors to ensure convenient access for all members of the Dublin community. Currently, the property is owned by the Alameda County Surplus Prop- erty Authority, and was designated for the City Park in the Eastern Dublin Specific Plan. While much of the adjacent property is undeveloped, the Specific Plan outlines a development scenario which features the park as a major focus of the community. The Specific Plan will direct the development of numerous single family neighborhoods, apartment com- plexes, commercial uses and an elementary school in the area immedi- ately adjacent to the Park site. Extensive infrastructure improvements are planned to accommodate this growth. widening and adding traffic signals on Gleason Drive. development of a four-lane, street with a median along the southern edge of the site (Central Parkway). infrastructure for water, power, sewer and storm drainage systems. improvement and enhancement of Tassajara Creek. development of a regional trail along the western edge of the site. The timing of these improvements and development will have a strong influence on the phasing of Emerald Glen Park construction.

[M~~~[D1 ~~[~ ~A~OC Site Analysis Extensive channel improvements and revegetation are proposed for Tassajara Creek. An East Bay Regional Parks bike and pedestrian trail, which will accommodate Flood Control Maintenance Access, is pro- posed along the top of the eastern creek bank. I I I . CHAPTER 2: THE SITE The Emerald Glen Park site is a 50:t-acre, rectangular and predomi- nantly level site. Formerly used as a military hospital, the only remnants of this previous use are two lines of mature Italian Stone Pines which lined the former entry drive, and random clusters of Eucalyptus and or- namental trees. This site is bordered to the north by Gleason Drive, to the east by Tassajara Road, on the west by Tassajara Creek, and on the south by the proposed extension of "Central Parkway". The site gently slopes towards the creek. However, storm water drain- age will be redirected towards the infrastructure within the roadways. I I I The physical nature of the site, combined with the cultural and climatic influences of Dublin, shaped the program response and design intent of the master plan. In particular, wind patterns, solar aspect, views (both to and from the site) and relationship to future uses have been studied to ultimately determine a logical arrangement of site components. Work- ing with these constraints, the goal is to create a unique response and a strong memorable statement. I Tassajara Road will be the "front door" of the Park for much of the Dublin community. While many of the adjacent residents to the west and north may arrive at the park along the future extension of Central Parkway, from Gleason Drive, or on the regional trail, the majority of the users first experience will be from Tassajara Road. Consequently, the intersection of Tassajara Road and Central Parkway will be the key Image zone. I I While located at the epicenter of the proposed residential and commer- cial development, Emerald Glen Park will not directly abut these uses. Rather, three edges of the site will be clearly defined by major roadways with generously landscaped setbacks and a pedestrian path. The fourth edge of the site will be Tassajara Creek with a minimum riparian corri- dor width of 200 feet.

Working with the City staff, the Recreation Needs Assessment for the Dublin commu- nity was updated to reflect revised population projections, changes in recreational trends, and current inventory of facilities. This updated rec- reation needs program was then distributed over the proposed park sites to ensure that at build-out of the park system, the facilities would meet recreation demand. This distribution of facilities was evaluated by the Park Task Force to identify a preferred program for Emerald Glen Park. Through meetings with students from middle and high schools, work- shops with the community and user groups, the Parks and Community Services Commission, this program was refined and prioritized. The final program includes: * Currently a task force is stud.ving the possibility of converting the existing Dublin Library into a senior centeJ: The reuse of the librmy is a preferred solution because of its convenient location to the existing Dublin senior popu- lation. If it is determined that the senior center will ultimately be located in the existing library. the pmposed senior center on Emerald Glen Park site will be developed with other park uses. THE MASTER PLAN Introduction Recreation Center/Gymnasium Aquatics Center I 90-foot Diamond Field 4 Tennis Courts Play Area Skateboard Park Amphitheater Satellite Restroom Facilities Hike and Bike Trails Senior Center * The Master Plan I The initial challenge for the Task Force was to determine the types of uses which should be located at Emerald Glen Park. The next step was to organize those uses on the 50I acre site. The Task Force also identi- fied additional elements which were not specific "documented commu- nity needs," but were still important to the park program - such as focal elements, central plazas and promenade. These refinements help give the park its personality and character while creating a visual and social structure. I I I A special place, be it a park, city hall or college campus, creates a unique feeling which conveys a positive image. This sense of image and place comes from the way the park components are put together to address the realities of the site. I I Elements of the park structure should include: I Community Center 3 60-foot Diamond Fields 3-4 Soccer Fields 2 Basketball Courts Lake System Terraced Garden Picnic and Meadow areas Parking for 450 cars Maintenance Yard Points of entry: The main ceremonial entry that will set the tone and a lasting impression for the park and the community. I Central visual focus: An element that can be seen as one drives and walks around the perimeter of the park. This look will set an image for the entire Dublin community. The lake system will fulfill that function at Emerald Glen Park. I I Links: These are vital pe- destrian connectors or prom- enades between parking ar- eas and buildings, between buildings and sports facili- ties and between parking and sports, and north and south park entries.

I I I I I I + CHAPTER 3: THE MASTER PLAN Personal scale places: Meadows, gardens, interpretive natural areas, and other such places offer an intimate scale setting and sense of enclo- sure for more private usage. Architectural crescent: This is a pedestrian-scaled "main street" which organizes the building entries. This element focuses on the Central Plaza / Town Square. The master plan structure must also be derived from the site factors. The following are considered in the design of Emerald Glen Park: 1. It is a large site and the user could be confused moving from one part of the site to the other, hence the components are organized to promote clear circulation within the park. I I I 2. The site is flat and lacks unique features with the exception of the creek. There is no high point for good views, no rock outcrops and no large, old oaks. Hence, it is our task to create this interest, char- acter and ambiance for Emerald Glen Park. 3. The site will have multiple entry points which must be linked and made obvious by special landscaping and signage. In very simple terms, the visual and experiential organization of the park boils down to these basic components: I Finally, the image of the park will be set by the character of the elements such as buildings, lighting, signage and materials.

Locate the primary entry along Central Parkway at a minimum of 750 feet from the Tassajara Road intersection, and align the oppos- ing cross street to provide the potential for future intersection sig- nalization. Design Objectives The visitor's perception of the park will be largely influenced by the design of the circulation system. Thus, careful consideration must be given to the components of this system, which includes the auto entry, the parking areas, the pedestrian drop-off areas, and the pedestrian and maintenance distribution system. In the park, where a wide variety of user groups are represented, it is essential to clearly direct visitors to their ultimate destination and to minimize conflicts between the differ- ent user groups; the wedding party and the swim team, the corporate picnic and the toddlers. This can be achieved by developing a hierarchy of trails and entries, based on path width, location and materials. 5. Align the western most project entry on Gleason Drive with the proposed entry to the residential development. This will facilitate future signalization and safe pedestrian crossing for regional trail. 6. Provide a minimum of two secondary vehicular auto entries at both Gleason Drive and Central Parkway to facilitate the distribution of vehicular traffic. Each entry may become associated with specific uses. Parking Areas Vehicular Circulation Auto Entry / Arrival The program for Emerald Glen Park envisions a minimum of 450 cars to be accommodated on site. These parking areas should be consistent with the park ambiance. The parking areas should be designed to: The design of the circulation system begins with the arrival at the site. As vehicular access is not permitted from Tassajara Road, site access is limited to Gleason Drive and the proposed Central Parkway. I. Create a crescent to link the architectural hub of the site and to pro- vide a park in close proximity to buildings without allowing park- ing to visually dominate the central space. Auto entries should be designed to: I. Create a strong first impression of the park, emphasizing views of the open meadows, lakes and architecture from vehicular entries. The image of the park, not the parking lots, should be the visitors' first impression 2. Locate vehicular circulation and parking at the perimeter of the site to encourage the use of the whole park. This layout will help to facilitate surveillance of the park from patrol cars and prevent con- flicts between vehicular and park activities. 2. Focus the primary entry on the pedestrian plaza/drop-off areas. 3. Subdivide parking areas to reduce the visual expanse of asphalt, and to provide parking closer to different uses. 3. Develop entry and drop-off areas with special plantings, signage, and other features that reinforce the character of the site. Create a sense of arrival. 4. Provide adequate parking stall widths to accomodate family-sized cars. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . [M[~~[D1 G~[~ ~A~OC 5. Limit access at night to some parking areas with lockable gates. concrete and accent pavers are possible material choices. The paved path within the promenade should be a minimum of 14' wide with numerous opportunities for seating along its length. This is the pri- mary organizing element of Emerald Glen Park. I I I . CHAPTER 3: THE MASTER PLAN 6. Provide strong links between parking areas and park destinations. 7. Provide a significant number of trees for shade, as well as to clarify pedestrian and vehicular circulation patterns. 8. Provide handicapped parking spaces adjacent to the main drop-off zones. 5. Provide a continuous loop trail system, 8' to 12' wide, surfaced for hiking and jogging. Markers should be spaced at regular intervals indicating kmlmiles jogged or walked. The trail surface may be a combination of asphalt, concrete, cinder and gravel as appropriate to the location in the park. I I Pedestrian Circulation The pedestrian system should be designed to: 8. Provide paved walkways suitable for handicapped access through- out the park. I I I I The pedestrian circulation system must accommodate park users mov- ing directly from the car to their destination, as well as those using the trail system to enjoy the ambiance of the park. The large size of the park makes it necessary for the pedestrian circulation to function as an orga- nizing element, thus providing a clear structure for the park. 6. Provide ample seating pockets with drinking fountains, bike racks and trash receptacles tucked into alcoves along the path system. 7. Link the pedestrian paths to the EBRPD regional trail and the low flow bridge crossing across Tassajara Creek. 1. Create a pedestrian hub at the Central Plaza which will function as a 'Town Square' and a ceremonial focus for the park as well as the community. Maintenance/Service Access 2. Create a 'Main Street' crescent that organizes pedestrian interface with the architectural entries. The trail system may also be used for park maintenance. Maintenance access system should be designed with maintenance staff to provide 10' wide paths for maintenance access throughout the park. Lockable gates should be installed to limit vehicular use. I 3. Develop a clear system of promenades to accommodate major pe- destrian circulation through the park. This promenade system should not only function as a link to the various sub-spaces, but also as a windbreak and a special feature in itself. I I 4. Utilize materials for the spine and plazas that are richer and more refined than materials used for paths in other parts of the park.

CHAPTER 3: THE MASTER PLAN LIGHTING Design Objectives A strong lighting concept can establish the presence of the facility from the road and orient users to the site. Lighting provides a visual link along the pedestrian circulation zones and creates a secure environment at night. Night use would be limited to the buildings, their related court- yards and hardcourt areas. General use of the park at night should be prohibited. Recommendations 1. Use special lighting treatment to highlight the park entry from the road and orient users to the site. 2. Provide lighting at the park entry and parking lots to promote safe night use of these areas. 3. Use special thematic light standards to illuminate and define the pedestrian promenade within the entry plaza. The style of lights should blend with the character of the park and buildings. 4. Use special lighting effects on structures, and up lighting of trees and water features to define night use courtyards. 5. Avoid lighting of the trail system, playgrounds, or other park fea- tures beyond the minimum required for security to discourage night use. 6. Provide sports lighting for tennis courts, basketball courts and skate- board area. Establish a lighting curfew compatible with the adja- cent area.

CHAPTER 3: THE MASTER PLAN Design Objectives 2. Plant formal grids or arches of trees to reinforce the scale of the spaces. The landscape imagery varies as the park visitor moves through the dif- ferent zones, in a gradual hierarchy from formal plazas to natural mead- ows. In addition, the overall approach to planting design will: 3. Provide shade for large plaza areas. 4. Create small, formal gardens which relate to interior building uses. Promote "xeriscape" techniques through the use of drought toler- ant plant material, appropriate irrigation design and proper installa- tion maintenance. 5. Provide dense planting that is also aesthetically tidy and neat. Se- lect appropriate planting for uses and activities. Plant trees and shrubs that are low in litter within the aquatics complex. I Consider maintenance practices in selection and placement of plant material, including use of mow strips along all turf edges, selection of pest/disease resistant plant species and proper spacing of materi- als for the ultimate size. I Windrow / Promenades Recommendations I. Be distinct and unique to Dublin. I I I I I The landscape concept for Emerald Glen Park has six categories: The formal windbreak character is consistent with the agrarian setting while providing a visual structure for the park. Double and quadruple rows of columnar trees should be planted to delineate promenades and create windbreaks. I. formal landscape zone 2. windrows/promenades 3. entry zone 4. parking lot zone 5. streets cape edge zone 6. open meadow / riparian zone Entry Zone Vehicular entries are located along Gleason Drive and Central Parkway. These are the areas that will provide the public with a first impression of the park, thus the entries should: Formal Landscape Zone 2. Be landscaped with formal trees, accent plantings, bedding colors, and formal hedges. I I I These are the people intense places and as such require a more refined, detailed landscape response. In this zone: 3. Use architectural features such as walls, colunms, pots or special paving to enhance the entry experience. [EM~~LD G~[~ ~A~OC .

Trees should be spaced and massed to provide shade, designate pedestrian circula- tion patterns through the parking areas, and frame views. The landscape character of the park transitions from green, pastoral mead- ows and more formally planted areas to a native creekside character, with annual grasses and scattered riparian vegetation. The meadows provide a soft, green area for picnics and informal sports as well as passive group and individual uses. These will be the open pastoral ar- eas in contrast to the more formal areas near buildings. The landcape at these zones should: . CHAPTER 3: THE MASTER PLAN Streetscape This area located in the right-of-way along three edges of the park is the first impression for the driver from the peripherial streets. The streetscape planting should: Meadows / Riparian Zones I. Generally conform to the streetscape character already developed for the perimeter roads. 2. Be modified to provide views into the site and frame focal elements such as the lake. Parking Lot Zone Landscape treatment within and adjacent to parking lots should rein- force the circulation patterns and provide ample buffer and shade. These areas should: I I I I I I I I I I I. Reflect the traditional pastoral park image; a soft, green turf meadow with berms and clusters of large canopy shade trees. I. Use low maintenance, low litter plant material. 2. Include windrows of trees and shrubs in exposed areas to reduce the impact of prevailing winds. 2. Include tree species that are able to tolerate the parking lot environ- ment, with confined root space, and reflected heat. Trees must also withstand the prevailing winds. 3. Create lightly-irrigated pockets with riparian trees and low shrub understory to complement the creekside character. 3. Include canopy trees to provide maximum shade for automobiles with sufficient branching height for buses and trucks. 4. Include a substantial buffer of evergreen trees along the western boundary to protect the adjacent homes from being impacted by park use. 4.

INFRASTRUCTURE and Tassajara Road water improvements are not yet defined and will be dependent on the development of the sites on the south side of Central Parkway, and Dublin Ranch to the east of the park. Storm Drainage Install an on-site storm drainage collector system with adequate number of catch basins, inlets and area drains in and around buildings, vehicle parking areas and other improved areas. The current site drainage is tributary to Tassajara Creek. The storm drainage master plan for the adjacent area calls for a 36" to 48" storm drain pipe to be installed and improved in Central Parkway improvement east of Tassajara Creek. The on-site drainage system will be tied into the Central Parkway system, which then directs the drainage to a proposed 48" outfall into Tassajara Creek at the future Central Parkway bridge location. Phase 1 of Emerald Glen Park will be served by the existing 14" water line in Gleason Drive and interconnected with future park phases and tied into Central Parkway once the Central Parkway water improve- ments are completed. Reclaimed Water Currently there are no reclaimed water lines adjacent to the Emerald Glen Park site. However, reclaimed water line improvements are pro- posed as part of the future improvements to Gleason Drive to the north (20"RW), Tassajara Road to the east (10" RW) and a Central Parkway to the south (8" RW). The Dublin Park site irrigation system shall be designed in way that a future connection to the reclaimed water system can be accommodated once the reclaimed water system is activated by the Dublin San Ramon Services District (DSRSD) in the area. The timing of the Central Parkway improvements are not yet defined and will be dependent on development of the sites on the south side on Central Parkway adjacent to the Dublin Park. In lieu of the Central Parkway improvements, the Dublin Park on-site storm drainage will parallel the northern boundary of Central Parkway and outfall into a new 48" outfall structure into Tassajara Creek. Sanitary Sewer Water Install 8" on-site loop water system connected to the Gleason Drive system and the future system in Central Parkway. The on-site loop wa- ter system will provide laterals for domestic, irrigation and fire protec- tion for the proposed buildings and facilities and other site water system improvements as necessary. The water system will become a Dublin San Ramon Services District (DSRSD) facility and will be maintained by DSRSD once improvements are completed and accepted. Install new sanitary services to each of the buildings and restroom fa- cilities proposed. The sanitary sewer services will be connected to the proposed future public trunk line in Tassajara Road or Central Parkway. Water services will be provided from an existing 14" water line in Gleason Drive, and proposed new water mains proposed in Central Parkway (14"W) and Tassajara Road (18"W). The timing of the Central Parkway Currently, there are no sanitary sewers adjacent to the Emerald Glen Park site in Tassajara Road or Central Parkway, however, a new sanitary trunk system will be improved in Tassajara Road by the Dublin Ranch project to the east of the Park site in the near future. The proposed future sanitary sewer main improvements will include an 18" sewer in Tassajara Road, 8" sewer in Central Parkway and an 8" sewer in a por- tion of Gleason Drive. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

CHAPTER 3: THE MASTER PLAN Electric/Gasffelephone Currently overhead utility power (21kv) and telephone exist in Tassajara Road on the eastern side of the park and in both Gleason Drive and Central Parkway on the west side of Tassajara Creek. No gas service is currently available immediately adjacent to the site. Existing underground utilities (Electric/Gastrelephone) on Gleason Drive at Hacienda Drive are currently being planned for extension to the west- ern limits of the Emerald Glen Park site at Tassajara Creek. These fa- cilities will have to be extended to Tassajara Road in the future as part of the Gleason Drive improvements between Tassajara Creek and Tassajara Road.

Focal Lakes The 0.5 acre lake with a 15 foot high wind-controlled, monitored water spout will be the visual feature of the park entry. The lake will create a unique image of soft pastoral character at the corner of Central Parkway and Tassajara Road - establishing a strong first impression. A formal, terraced overlook located at the end of the pedestrian promenade pro- vides a symbolic point of origin for the water source - a small fountain element. The water will spill down the terraced seatwalls into the lake. A sculpture/gazebo at the end of the promenade will provide a focal A second proposed 0.3 acre lake adjacent to the community center will be a visual backdrop to a variety of active and passive park uses. The edge treatment will vary from an urban, more formal concrete steps at the overlooks, to a more natural edge. For health and safety concerns, no swimming will be allowed in the lakes. A full recirculation system will be necessary to maintain clarity with a possibility of using the water from the lakes for irrigation within the park.

CHAPTER 4: PARK COMPONENTS Architectural Crescent and Central Plaza Architectural Crescent The Central Plaza, at the terminus of the main entry drive, is a ceremo- nial area for events such as Fourth of July celebrations, bicycle races, marathons, and art displays. The Community Center, Aquatic Center and Recreation Center are arranged in a crescent to provide architec- tural enclosure, creating a sense of a town square. Multiple points of ingress and egress, combined with window walls and arcades that ex- tend into the plaza, will interlock the building mass with the plaza space. Food concession areas should be located in this zone to support park uses.

Equipment will be cus- tom designed to create a distinct ambiance for Emerald Glen Park. Edu- cational opportunities such as animal prints, a rose compass stamped in paving, or metric measurements on the wall surfaces can enhance the play value. Berms, low wall, plantings, and pedestrian entry elements will enclose this space to create a distinct world, and protect it from the surrounding park uses. The Play Area will be divided into two distinct sub-spaces, one for beginning play, and the other for advanced play. A concrete path will border the play areas and provide a track system for the children's wheel toys. A participatory water element will be the visual focus of the space, creating an opportunity for children's water play. Shaded Parents' Area Seatwall i The design includes a shaded parents' seating area overlooking the en- tire play area. This will be where parents can relax and socialize while supervising their children. Parking, drinking fountains and restrooms will be provided in close proximity to the play area.

The Promenade Ballfields A 40' wide, tree-shaded promenade will extend from the lake to the northern plaza, with a cross axis to the creek creating strong pedestrian links between the various parts of the site. The Promenade will func- tion as a collector for people from the parking areas as well as a place for pedestrian activities such as street festivals and fairs. Focal points, highlighted with colorful plantings, will be located on each end of the Promenade. Both the Promenade and Central Plaza will be special spaces, and their uniqueness will be enhanced by the use of paving materials that are higher quality than materials found in other parts of the park. The sports fields identified for the Master Plan include 3 60-foot dia- mond fields, I 90-foot diamond field, 3 independent 330' x 220' com- petition soccer fields and a fourth soccer field overlapping the ballfield area. To minimize the impact of the sports fields and to keep them from dominating the whole park, they have been distributed throughout the site. The fields will be enclosed by vegetation, and as far as possible, serviced by their own parking area. Information kiosks with game sched- ules will be located at the entrances by the parking lots, directing the players and spectators to their fields. Rows of Columnar Trees Delineate Promenade A restroom facility to support sport field use will be located at the west- ern end of the east/west promenade. A concessionnaire may also be developed. Fields will be designed and arranged to maximize playabil- ity and use, and oriented to avoid the low angle sun. Group picnic areas with barbecue facilities will be located near the fields. These areas may be rented out to large groups or used for informal family gatherings associated with athletic field use.

Basketball Courts Both the Task Force and the community emphasized the provision of hardcourt facilities such as basketball courts, tennis courts, and a skate- board park. These hardcourt areas should be designed with a high-qual- ity theme visually consistent with the overall park. The Master Plan includes 4 lighted tennis courts. The court area will be designed with a sign-up kiosk, seating, drinking fountain, picnic tables and informal play area. Trees and wind screens will be used to buffer winds. The tennis courts will be located near parking. A back board will be provided for tennis practise. Tennis Courts Parking The Master Plan provides 2 full-size basketball courts. Seatwalls and berms will be used to enclose the court area for ball control and to pro- vide seating for spectators. The basketball courts will have a refined plaza character - scored con- crete to demarcate court lines, with special walls, entry fea- tures and lights to define bas- ketball territory. The basket- ball courts will be conve- niently located to parking, and will be separated from chil- dren/family gathering areas. Shade Trees for Enclosure Painted Stucco Walls for Seating . CHAPTER 4: PARK COMPONENTS Skateboard Park The skateboard park should not only be challenging, but be visually integrated with overall park theme. This facility should be located near a parking area and be buffered from other park uses. The design of the skateboard park will create separate sub-spaces to allow varying degrees of challenge and avoid conflicts between skill levels. A shaded spec- tators' overlook/rest area will be developed. The de- sign will address evening lighting of facility and easy survellience. Upright Tree, Rows along Promenade Wind-Protected Amphitheater Section through Amphitheater and lake Amphitheater I I The amphitheater is designed to support both informal picnics and sum- mer concerts or plays. While not designed to fulfill all the theatrical needs of the community, it will provide opportunities for small scale casual events. The following are measures considered: I I I. Grades are sculpted to create a wind-protected bowl looking towards the small lake and community center. I 2. Lawn is terraced to provide casual seating for events. The bowl is oriented towards the northeast to avoid late afternoon sun. I I 3. The existing pine tree grove is maintained to provide a backdrop and additional wind protection. 4. A raised concrete step with open column framework is used as an informal stage. Power is provided to the stage area for lighting and sound equipment needs. I I 5.

Restrooms Several small satellite restrooms will be strategically located through- out the park to provide for peak use. These structures will be designed to blend with the architectural character of the park, while providing durable, easily-maintained fixtures. Restrooms will also be accessible from the maintenance paths throughout the park. The Aquatic Center, Community Center and Recreation Center will have ample restroom facilities to serve park users. Maintenance Facility A 0.5 acre maintenance facility for Emerald Glen Park is planned for the northwest corner of the site. It is anticipated that this area will pro- vide storage and workspace for the maintenance staff. Storage area will be provided for equipment, fertilizers, mulch and other items limited to specific needs associated with Emerald Glen Park. The maintenance facility will be enclosed by an attractive fence and dense vegetative screen. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

To this end, all the buildings have been clustered in one location and oriented to an inward facing crescent for pedestrian and auto circulation. I Architectural Crescent I The concept of Emerald Glen Park is that it will be a unique and diverse place for family-related recreational activities. In line with this concept and in order to capture the spirit of the park's overall diversity and ex- citement, the buildings are envisioned as a family of structures housing different uses and functions connected through common themes in a crescent shape which is oriented towards the park entry. While each of the buildings has not yet been designed, it is anticipated that the com- mon elements which create the crescent will include connected walk- ways, covered arcades, landscaping, and specific building forms and materials (such as roofs, windows, and exterior colors). Freizes or other decorative elements can also unify the various building types. Each structure should have its own unique character, clear but discrete sense of entry, and expression of function. All main building entries should be articulated with strong volumes like towers or roof forms. I Each structure should have its own separate identity, and should be leg- ible in its function to avoid confusion amongst users. I The pedestrian crescent should have a grand scale encompassing the parking areas and visually organizing the individual structures. How- ever, it must also have a human scale that will be comfortable for seat- ing, meeting, and gathering. I I Relationship of Buildings Structures that are two-story high will create an enclosure for the park- ing area, as well as provide a visual statement seen from periphery streets. I While it is important that the buildings have a strong relationship to one another and read as a family of buildings, it is not necessary that they look exactly alike. Variety and diversity within a unified theme, similar to that of a European village, where the use of similar materials and details integrate diverse building types and sizes is the goal of the de- sign concept. Building materials should be permanent, classic and low maintenance facades such as stone, tile and stucco. I Building facades (fenestrations, signage and detailing) should be part of the richness and vitality focused on the pedestrian crescent. I Each of the individual structures need to be related to each other. They must have a family of similar forms (roof pitch, overhangs, facade). All structures should be linked by an all-weather enclosed arcade, porch, trellis or some consistent device. Building Needs Assessment Space Definition During the Parks & Recreation Master Plan development, a needs as- sessment of recreation facilities was prepared. The City's inventory of indoor facilities currently limits some recreation programming. Many of the city-sponsored programs are overcrowded and/or enrollments are restricted. Programming limitations will be exacerbated by the increas- ing population and the changing demographic profile of the community over the next 20 years. I I Another important goal of each building's design is to relate positively to exterior spaces rather than be structures that dominate the surround- I I [M[~~[D1 G~~~ ~A~OC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . I I I I I I I I I I I I I I I I CHAPTER 5: ARCHITECTURAL COMPONENTS. The needs assessment examined patterns of use to determine if existing facilities are fully utilized. The study confirmed that existing facilities are programmed to their limit, and thus, the Master Plan identified new recreation facilities that are necessary to meet program demand that can- not be met elsewhere in the community. private sector. A new library was initially considered for location at the Emerald Glen Park site, but it was determined that the Civic Center site better meets the community needs. A new Senior Center is presently identified on the Emerald Glen Park Master Plan. However, a study is currently underway of the existing Dublin Library building to determine if it could be renovated for use as a Senior Center in the event that a new Library is built at the Civic Center. If it is determined that the Senior Center should be housed in the Library building, the Emerald Glen Park Master Plan will be modi- fied to reflect the elimination of the Senior Center. During the development of the Emerald Glen Park Master Plan, several additional facilities such as a Library and full service daycare were iden- tified as being in high demand, but it was determined that they were not appropriate to this particular site. Currently, full service day care is not provided by the Parks and Community Services Department, but by the Tree Grove with Seating Auto Court and Drop-Off Gymnasium Fountain Community Center Section through Entry Crescent . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

CHAPTER 5: ARCHITECTURAL COMPONENTS I COMMUNITY CENTER Program Elements for Community Center (Based on Dublin Parks & Recreation Master Plan Standards) I The goal of the Community Center is to provide a comprehensi ve multi- purpose center which responds to the recreational, cultural and social needs of all residents of Dublin. This Center must be designed for use by all ages and abilities, including senior citizens, teens/preschoolers and their parents. The indoor facilities will provide diverse and chal- lenging opportunities to develop and enhance human potential through creative activities and experiences. Lobby/Reception - 1 ,500 sf Within this area, access control, registrations and equipment issue will be allocated. A lounge area is provided for waiting and relaxing before or after using the facilities, and it may accommodate art displays. I I The Community Center must ensure long term effective resource man- agement while focusing on issues of access and public safety. The de- sign and location of the Community Center will improve access to rec- reational activity and offer the best possible facilities to the public. Classrooms/Meeting Rooms - 1.200 sf Two rooms designed to accommodate a wide range of activities includ- ing classroom instruction, community meetings, small lectures and work- shops, table games, crafts and other similar activities. I I The facility should be a vital building which provides a variety of rooms in various sizes, to meet the program needs of community organizations and activities. Additionally, potential for revenue generation should be considered as substantial amounts can be raised to meet the City's cost recovery objectives. Office Area - 1.000 sf Administrative and clerical offices for the Community Center staff. The office suite includes staff offices, a small conference room and work- room. The conference room would also serve the needs of the commu- nity for public or club meetings, small workshops and classes. I The Community Center should serve as a focal point and a source of pride for the community. A building area of approximately 25,000 square feet will be needed at Emerald Glen Park to meet the projected commu- nity needs. Community Hall! Assembly Facility - 5,000 sf This is a large attractive social space with desired amenities for recep- tions, parties and meetings. The building program includes a commer- cial kitchen and adjacent restroom facilities. The space would be very flexible and could include a portable stage and dance floor. I I I The Community Center should be designed as a part of the entry cres- cent. There should be a strong relationship between interior and exte- rior uses, including individual courtyards and patio space for use by teens, seniors, weddings and receptions. Commercial Kitchen - 800 sf This incorporates a full service caterer's kitchen for large social events in the Community Hall, as well as smaller functions in the multi-use rooms, Senior's Activity Area, Teen Lounge and patio/garden areas. The kitchen would also be designed as a demonstration classroom for cooking classes.

Treat this fa- cade with architectural enhancements and landscaping to create a comfortable relationship between the structure and pool area. I The Aquatic Center will be a dynamic, multi-use facility that provides programmed and drop-in recreational opportunities for the entire com- munity. This pool would supplement the existing City Swim Center, and would serve the needs of youth and adults who participate in age group swimming, synchronized swimming, water aerobics, other fitness programs, and the full range of instructional classes. I 7. Provide a shade structure close to, and possibly over a portion of the tot wading pool. Enclose tot pool area to prevent access to deeper pools. I According to the Parks & Recreation Master Plan, the aquatic center should include a 50 meter by 25 yard with a shallow water "L", a tot wading pool, and a fun pool with features such as slides and sprays to increase family and youth participation and generate additional revenue. The Aquatics Center should: 8. Provide outdoor showers, multi-level pool deck areas, lawn, shade canopies and picnic facilities to enhance the aquatics center. I 9. Provide a concession/snack bar area; possibly operated by an inde- pendent concessionnaire to generate revenues and provide food ser- VIce. I 1. Provide a sufficient and flexible inventory of pools to meet the di- verse and changing aquatic interests of the current and projected population. 10. Enclose the pool area with a combination of berm, landscape screen and fencing to provide security and visual separation from other park uses. I 2. Develop aquatics facilities and the related amenities that will en- courage family participation and recurring use. 11. Provide indoor facilities to support aquatic uses. Indoor facilities should include: I I 3. Provide facilities to meet the demand for instructional aquatics pro- grams and provide the opportunity for all residents of Dublin to learn to swim.

CHAPTER 5: ARCHITECTURAL COMPONENTS The Recreation Center or Gymnasium is envisioned as a dynamic, multi- use facility that provides structured programs and drop-in recreation opportunities for the entire community. It will provide residents of all ages with access to indoor recreation. This dynamic and versatile build- ing will be tailored to the needs of youth, families and adult team activi- ties. It will not be designed to serve as a spectator facility for competi- tive sports, but rather to provide spaces where residents of all ages and abilities can participate in healthy activities. Gymnasium - 16.000 sf Large, high-ceilinged, wood floor space designed to accommodate one (1) basketball feature court with bleachers, or three (3) basketball cross courts, or four (4) volleyball courts, or six (6) badminton courts. In- cludes storage area for equipment. The scale of the gymnasium requires special consideration to ensure a structure which blends with the other features of the park. Long facades should be articulated with architectural detailing, as well as landscap- ing. The building entry should be emphasized with a vertical tower, and arcades should be used to create a pedestrian scale at the building pe- rimeter. Lobbies of the gymnasium and aquatics center should be spa- tially connected. Office Area - 600 sf Small administrative offices for staff. I I I I I I I The Recreation Center forms the western edge of the building crescent. To meet the projected demands of the community, an approximate build- ing area of 30,000 sf will be required. Appropriate relationship between interior and exterior uses should be considered. Locker Rooms - 3.600 sf Provide separate male and female showers, rental locker area, restroom and dressing area. Activity Lobby - 1.200 sf Access control location. Lobby area possibly shared with Aquatic Cen- ter. Include passive area for Reception Counter, socializing, displays and disseminating information. Program Elements for the Recreation Center (Based on Dublin Parks & Recreation Master Plan Standards) Aerobics/Dance - 2.000 sf Designed with dance bars, mirrors and specialized wood flooring, this space will provide a high quality instructional room. This facility would meet a wide range of program needs including all types of dance, yoga, stretching, back care, children's tumbling, teen poise, etc. I I I [M[~~[D1 ~~~~ ~A~OC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Design Objectives In group picnic areas, provide heavy duty tables and larger barbeques sites. Arrange groupings in such a way as to make them convenient to reserve for group functions. In developing a palette of materials for the site amenities, two main goals were kept in mind. Firstly, to provide elements which will en- hance the enjoyment of the park by a wide range of visitors, and specifi- cally to emphasize the distinct character of the various settings. The site furniture helps to distinguish the more formal areas from the more natural, casual parts of the park. In addition, site amenities located within heavily used park must be durable and easy to maintain. Seating Provide park benches frequently along the trail system. Benches should be durable and easily maintained. Locate more contemporary benches with backrests in the plaza spaces and along the promenade. They should be visually compatible with the architecture. Provide low walls which define the use spaces and offer opportuni- ties for casual seating. Appropriate locations include the children's play area, the front of the Community Center, the Aquatic Center, and in the plaza spaces. These low walls should be made of sand- blasted concrete for durability and maintenance, detailed with re- veals, insets and color for visual interest. Picnic Tables and Barbeques Picnic tables of durable material should be located throughout the park. Individual tables on round concrete pads should be located along the trail system. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . lliMlli~W I[;U/NI r~AR(OC ~ '1i . CHAPTER 6: SITE ELEMENTS I Signage I space. The classroom areas require movable tables and chairs, while the Community Center courtyard might contain a small water fea- ture. I Locate directional signage throughout the park in key areas. Pro- vide mounted park plans of durable material illustrating key desti- nations within the park. Consider the needs of special use groups like the disabled, sight impaired, seniors and young children in the design and placement of amenities and signage. I Incorporate and cluster signage on building facades, kiosk struc- tures and fences wherever possible to minimize clutter in the land- scaped areas. I Utilize positive, friendly statements such as, "Thank you for not eating in the pool area". I Coordinate graphics, materials and colors with the architecture when located near buildings. I Provide opportunities for dedication plaques for donations and vol- unteer efforts. I Miscellaneous Use portals, window wall systems or overhead arbors to define the entries to special areas. Portals can provide opportunities for at- taching fences, shade structures or signage and should be designed to harmonize with building details and colors. I I Locate trash receptacles and drinking fountains appropriately throughout the park. Provide I trash receptacle per 2 picnic tables in picnic areas. Drinking fountains should not be placed near sand areas and should be installed with hose bibs at the base. I I Introduce special elements to the plazas and formal garden areas, each having a character which supports the activities taking place. The art-related courtyards might have sculpture pads and display I I [M[~~D ~~~~ ~A~OC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

The purpose of this fee is to finance municipal public facilities to reduce the impacts caused by future developments in the City of Dublin and East- ern Dublin. These facilities include the completion of the Civic Center office space, construction of a new library expansion of the existing library, relocation and expansion of the existing senior center, acquisi- tion and construction of neighborhood/community parks and commu- nity buildings (including a community theater, a community center, a recreation center and an aquatic center). The Public Facilities Fee is subject to periodic review and update by the City Council to insure con- sistency with increments of construction costs. The development of Emerald Glen Park will be undertaken in phases based on the availability of land and funding. It is anticipated that about 19 acres will be available for Phase I development, and will cost ap- proximately $3.2 million. Facilities will include: 2 60-foot Diamond (without lighting, with backstop) 1 90-foot Diamond (without lighting, with backstop) 1 Soccer (overlap with baseball) 1 Soccer (regulation) 2 Basketball (with lighting and seating) 4 Tennis Courts (with lighting) Skateboard Park Play Area Picnic Areas Plaza Promenade Based on the cost estimates associated with Emerald Glen Park, as well as the consultant's recent experience with the costs for similar projects, it is anticipated that it will be necessary to update the Public Facilities Fees in order to construct the park as designed. The Emerald Glen Park Task Force came to a consensus that Phase I should consist of facilities that meet the needs of different user groups, and that no single facility or use should dominate the park. Due to the infrastructure improvements schedule, the first phase of the park will be constructed with access from Gleason Drive. Subsequent Phasing The Emerald Glen Park Task Force reviewed possible scenarios for the second phase of development. The consensus was that those elements which are essential parts of creating the "signature park" image should be constructed as soon as possible. Specifically, the Task Force empha- sized the development of landmark features at the TassajaralCentral Parkway intersection, the building crescent and southern plaza. The community center and associated park, lake system, focal gazebo, meadow, promenade and the additional picnic areas should be devel- oped in the second phase. Based on the availability of funds, the gym- nasium and aquatics center (additional soccer fields and volleyball courts) may be built in the second or third phase. The amphitheater, additional baseball fields, and sculpture or terraced gardens may be delayed until the final phase. 1 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . [MUAW lGUIi\! Il'Ar~1K , In the decision-making process of Phase 1, the Emerald Glen Park Task Force identified alternate playfields to be used during the renovation of the Dublin Sports Grounds. When the 1996-2001 Capital Improvement Program was developed, it was anticipated that the facilities in Phase I of Emerald Glen Park would provide adequate replacement fields. + CHAPTER 7: PHASING / ,~.". .,':; '.
