BACKGROUND The Western Dublin Study began in 1989 with the application by Eden Development Group and Schaefer Heights, Inc. for a- proposed residential community of about 4,300 -units on 2,942 acres. The applicant's current proposal is for 3,131 units. Signature features of the- project would include an 18 hole championship golf course, executive. homes clustered around the golf course, a variety of other ---------- --- ---------------------------------PP------------------- ITEM NO. COPIES TO: A licant/Owner Senior Planner CITY CLERK Project Planner FILE lqD Agenda File lj� Application File housing products and a community/commercial center that would serve the daily shopping needs of onsite and nearby residents. Shortly after submittal of the Eden Development application, an adjacent property was added to the study at the request of the -then current owner. The Cronin Ranch (now owned by- Milestone -Land Development -Corporation); was included in the Western Dublin Study on July 26, 1989. At that time, 143 dwelling units were proposed for the 175 acre site; the applicant's_current proposal is for 125 units. Because these proposals would require a- general plan amendment, the- City undertook a multiphased planning approach to the-project. - The-City contracted with WPM Planning Team to prepare a general plan amendment, specific plan and environmental impact report. In addition,- the City retained the -services of a planning and management consultant, Brenda Gillarde, to coordinate the planning process for the City. During the planning phase of this project, five reports were -published. All are available at the City of Dublin Planning Department for review. Study Report 1: Existini; Conditions. Identifies the -environmental, physical and -planning constraints and opportunities for development in western Dublin. Study Report 2: Alternatives and Policy Considerations. Discusses alternative land use approaches for western Dublin and the implications of existing General Plan policies. Study Report 3: Specific Plan. Establishes detailed policies for development in western Dublin, including land use layout, infrastructure, financing and other issues. Study Report 4: Generale Plan Amendment: Identifies necessary changes and additions -to current general plan policies -and map in order to accommodate the development concept proposed in the Specific Plan. Study Report 5: Environmental-Impact Report. Assesses the impacts associated with implementing-the Specific Plan and recommends mitigations to reduce impacts. In addition, three public-study sessions were held jointly with -the Planning Commission and City -Council on the Western Dublin project pursuant to Government Code Section 65351. The content of those meetings and City Council direction is briefly summarized below. Study Session 1: Existing Conditions, Opportunities and Constraints. December 13, 1989. Presented information on environmental conditions of the property, identified site constraints and opportunities for development. Study Session 2: Land Use and Policy Considerations, February 28, 1991. Presentation of different land use options for western Dublin. The applicants proposed projects were selected Page 2 of 5 for further study. The other options were included in the EIR alternatives analysis. Study Session 3: Visual and Parkland Issues. - September 11, 1991. Presented initial visual analysis of development in selected areas of the site. Discussed linear park concept for Hollis Canyon. Consultants -were directed- to prepare additional visual analysis showing matured project landscaping. The basic concept of a linear park for Hollis Canyon was supported and a proposed road over Skyline Ridge was indicated for emergency vehicle access only. II. DISCUSSION The purpose of the May 12 public hearing-is-to receive comments on the General Plan Amendment and Specific Plan, as recommended by the Planning Commission (refer to Section B below for-further discussion). Notice of tonight's public hearing was made pursuant to Government Code Section 65090. The City Council should not deliberate on the General-Plan Amendment or Specific Plan until the public hearing is closed on these two documents. Public hearings on these two documents were held before the Planning Commission in 1991 and 1992. (Refer to Section A below for the major issues raised during these -meetings:) Notice of the General- Plan Amendment was- also sent to local, county, subregional, state and federal agencies pursuant to Government Code Section 65352. Public hearings on the Final EIR- were-also conducted before the Planning Commission. No -further public hearings on -the Final EIR will be held before the City Council. However, the City Council must consider the Final EIR before taking action on the General Plan Amendment and Specific Plan. A. Major Issues The major issues raised during the Planning Commission public hearings and subsequent Planning Commission meetings included: the proposed Brittany Drive extension a proposed public street over Skyline Ridge future water supply future wastewater treatment capacity concern that existing residents will pay for "new" water destruction of oak woodland destruction of riparian woodland development above the 740' elevation and associated visual impacts excessive-construction dust= - - - open space maintenance and management Page 3 of 5 B. Recommended Changes As a result of public and Planning- Corn mission discussions, the Planning Commission recommended various changes to the specific plan and general plan amendment documents as noted below. 1. Planning Commission Recommended Changes to the General Plan Amendment The Planning Commission approved -a number of minor modifications to the wording- of the General Plan Amendment (see Attachment 2). The most significant of the modifications was a- change to the general plan land use map to reflect a maximum of 74 units, not 125 units, on the Milestone property. 2. Planning Commission Recommended Changes to the Specific Plan The Planning Commission approved a number of minor adjustments to the policy language in the Specific Plan (see Attachment 3). Most of the changes were to clarify existing language. The Planning Commission also-recommended three major-land use modifications to the specific plan map: 1) reduce the maximum number of units for Milestone to 74 units;-2) delete the Brittany Drive extension-from -the plan; -and 3) designate a southerly alignment for the emergency vehicle access road connecting to the Eden/Schaefer development. C. Discussion at the May 12 Public Hearing The purpose of the public hearing tonight is to receive comments from the public on the Western- Dublin General Plan Amendment and Specific Plan as recommended for adoption by the Planning Commission. This public testimony will be heard and considered by the City Council in their subsequent deliberations on these two documents. The City Council should not deliberate or direct Staff on the Western Dublin project until the public hearing is closed on the General Plan Amendment and Specific Plan. Persons wishing to -make comments -are requested to speak only on the General Plan -Amendment or Soecific Plan, not the environmental impact report- The public hearing on -that document is closed and will not be reopened -before the City Council. The public hearing -tonight (May 12) will be. continued, if necessary, to Thursday, May 14 to receive additional public comments. III. CONCLUSION As mentioned above, the May -12 public hearing may be continued to May 14 to receive additional public comment on the General Plan Amendment and Specific Plan. After all public testimony is-heard on these two documents, the public comment portion of the City Council meetings will be closed. Page 4 of 5 Additional meetings will -be scheduled for the Council's discussion and deliberation on the Final EIR, Findings, Statements of Overriding Considerations (if necessary), Mitigation Monitoring Program, the- General Plan Amendment and the Specific Plan. The first set of-meetings is tentatively scheduled for May 27 and 28 for the purpose of Council discussion and-deliberation. on the Final EIR, General Plan Amendment and Specific Plan. - The Council will be requested to indicate their direction to Staff on these documents via "straw votes." Following the Council's deliberations and "straw votes" the staff will prepare draft resolutions on the three documents -for Council- consideration at the next set of meetings, which are expected to occur in early July.

There is easy freeway access, and perimeter ridges provide visual and noise screening. The western Dublin site provides an unusual opportunity to provide a large amount of new housing without creating major visual, noise, and traffic impacts on existing neighborhoods. In other ways,however,the environmental sacrifice is high.Massive grading and considerable tree removal would be necessary to build proposed housing on the site. The site has numerous other environmental constraints which must be acknowledged. The steep terrain and remote location limits opportunities for walking or bicycling to work or other destination. The Specific Plan Approach Throughout the planning process for western Dublin, the consultant team, development con- sultants, and City staff have searched for ways to reconcile these concerns, retaining the key open space values of the Western Dublin Planning Area while providing much-needed housing- in a strategic location. ,hatit In a series of intensive meetings, considerable progress was made in reconciliation of environmental concerns with the economic objectives of applicants. Through this process,some basic realizations emerged. • Need for a flexible planning approach.As the Bay Area enters the 1990s,many communities are struggling with the realization that the easy, "flatland" development sites are disappear- ing. As the region continues to grow, and the demand for strategically-placed housing continues to rise, development pressure is increasing on scenic, hilly areas such as western Dublin. Standard rules,written when abundant level land was available for development at low densities, no longer can be applied effectively to more difficult hillside terrain. The Dublin General Plan has recognized the need for flexible planning of western Dublin.This Specific Plan is an effort to provide this planning approach for western Dublin. • Need to balance open space and development values.The Specific Plan focuses on ways to maintain an effective open space corridor across the Planning Area, while clustering development away from this corridor. About 60% of the site is retained in permanent open space, including key wildlife habitat and other areas with important open space qualities. Development is concentrated in less sensitive sections of the Planning Area. • Recognition of development costs. In contrast to a more typical site located on the urban fringe,very high expenditures would be required in order to develop this site.In particular, major freeway improvements and wastewater facilities would be required.This has impor- tant implications for basic planning decisions for the site.If urban housing and recreational facilities are to be added in this area, the City must accept the fact that large-scale urban development is necessary to support these heavy capital costs. The Specific Plan has included economics as a major determinant in planning for western Dublin, and this plan is intended to provide for economically-viable development while meeting the City's own environmental and economic goals. 1-5 A:\8%4-SP�S914-SP ID 2. SUMMARY 2.1 The Western Dublin Specific Plan = In response to development proposals in western Dublin, this Specific Plan is being prepared to provide detailed direction for land use distribution, location of streets, utilities, financing mechanisms,development standards,and environmental protection.The Specific Plan(Western Dublin Report 3) is part of an extensive planning process for western Dublin, including collection of information on existing conditions, evaluation of alternatives, and preparation of an environmental impact report. 2.2 The Specific Plan Concept The Specific Plan envisions western Dublin as a predominantly residential community, with much of the site preserved as permanent open space. Homes are clustered into neighborhoods, separated by wooded ridges and canyons.A championship golf course is a major feature.Streets, boulevards, and parkways provide attractive and functional access and circulation. A network of bicycle and pedestrian paths include a regional trail link. The Specific Plan protects key environmental resources. An innovative off-site wastewater treatment system recycles water, and design features emphasize conservation of energy and other resources. A pedestrian- oriented Village Center serves as a focus for the community, and other neighborhood and community facilities are provided. There is a diversity of housing options, and affordable housing is included as an essential part of the community. 2.3 Land Use and Housing Summary Residential and open space land uses are predominant in western Dublin,with about 60% of the site reserved as permanent open space. The Land Use Map (Figure 3-1) shows the types and distribution of land uses planned for western Dublin. Land Use Classifications Residential uses range from existing rural residential homesites on large parcels to apartments at a maximum density of 25 units per acre. More than half of the housing units are detached single-family dwellings. Commercial uses primarily serve the local needs of western Dublin residents. Three types of commercial areas are planned: 2-1 AA8914-SP\8914-SP2 Summary 2.4 Traffic and Circulation Summary The Specific Plan emphasizes the use of alternate transportation modes, including pedestrian circulation, bicycles, and public transit as well as private vehicles. Interstate 580 borders the Planning Area on the south, with an existing interchange at Eden Canyon Road and an opportunity for a second interchange at Schaefer Ranch Road. Streets and Highways The street system for western Dublin is planned for efficient traffic flow, safety, community design values, and environmental concerns. Basic design considerations.Policies are included on future freeway interchanges,intersections, and driveway access. Community design values. Streets are designed to State (Caltrans) and City of Dublin design standards to enhance community design values, with a clear sense of orientation and identity. Travel lengths are minimized. In recognition of the steep terrain and other environmental considerations in western Dublin,streets are kept to a minimum width essential to meet access and safety needs. Alleys would be considered for use. Linkage between West and Central Dublin. Dublin Boulevard is extended to connect western Dublin with the existing community.Because of difficult terrain, a visually-sensitive ridgeline, and possible unwanted traffic on existing residential streets, no other major street links to existing areas of Dublin are proposed. Arterials: Hollis Canyon Boulevard will serve as the main east-west street link in western Dublin,with four lanes, a landscaped median,bike lanes, and pedestrian walks. Dior Collector: Dublin Boulevard will be extended to the Planning Area. Residential Access Streets • Shell Ridge Road will be an access street with special design standards,due to steep terrain. • North Ridge Drive and Skyline Ridge Drive are planned to provide access to homes around the golf course. • Cronin Ranch. Existing streets extended to the Cronin Ranch are designed to minimize. environmental disruption and effects on existing neighborhoods. (An emergency vehicle access route is planned to connect the Cronin Ranch with the rest of Western Dublin.). 2-3 A-.\8914-SP�8914-SP2 Summary Other Local Access Streets • Morris propeM access will be coordinated with the linear park in this area. Local residential streets are designed as akeypart of theresidential living environment.Avariety of measures will control traffic speeds. Public Transit - The Specific Plan provides for apartments, shops, and offices to be clustered around transit stops.The Plan calls for BART to establish express bus service in western Dublin.Park-and-ride facilities will be provided. Local transit service will be extended to the Planning Area, with convenient and comfortable transit stops. Pedestrian Circulation A network of sidewalks and trails will provide safe and convenient ways to walk to the school, Village Center, and other destinations in western Dublin. Pedestrian trails are also planned for recreation. A north-south regional trail link will be provided across the Planning Area, with access trails, trailheads, and staging areas. Boulevard walks will meander along the sides of Hollis Canyon Boulevard.L�will provide optional pedestrian walks between neighbor- , hoods. Sidewalks will be required. Convenient access walks will be needed from residential areas to the Village Center.Intersections will be designed to be "pedestrian-friendly". Bicycle Circulation While the steep terrain presents a limitation to bicycle use in western Dublin, a network of bicycle routes is planned to provide opportunities for bicyclists, including bike paths separated from vehicles and bicycle lanes along major streets. Parking While convenient parking is important, large expanses of parking lots can have adverse environmental effects-The Specific Plan identifies opportunities for reducing parking require- ments, including shared parking in mixed-use areas as well as provision for alternative transportation. 2.5 Sewer, Water, and Drainage Summary Domestic Water System The Dublin-San Ramon Services District (DSRSD) will provide water service to wester Dublin*with tireeted potable water supplied by the Alameda County Flood Control and Water Conservation District,Zone 7. Current district sphere of influence,boundaries and facilities will need to be expanded in order to provide water to the Planning Area.Water conservation will be 2-4 A.\8914SA8914-S P2 Summary emphasized in planning new development. With procedures established in the Specific Plan, adequate water service would be available to serve projected uses in western Dublin. Wastewater Future development in the Planning Area would also be serviced by the DSRSD. The district boundgy and sphere of influence needs to be expanded to take in the entire Planning Area. Conventional sanitary sewer service is constrained by lack of off-site wastewater facilities. However,the Eden Canyon Country Club development would include wastewater reclamation, with reclaimed water used for golf course irrigation.With procedures established in the Specific Plan, adequate wastewater service is available to serve projected uses in western Dublin. Drainage and Water Quality The Western Dublin Planning Area lies within the Alameda County Flood Control and Water- Conservation District. Flood hazards. The Planning Area is not subject to substantial flooding hazards. The Specific Plan includes policies to minimize any increased potential for erosion or flooding. Water quality. The plan includes policies and action programs to protect and enhance water quality. A_lteration of existing streams. Drainage facilities in western Dublin are planned to minimize adverse effects on existing stream channels. 2.6 Community Services and Facilities Summary The Specific Plan makes provision for the following community services and facilities: Schools The Planning Area is currently in the Castro Valley School District.The Dublin Unified School District is interested in annexation of this area.Resolution of this annexation issue may need to be referred to the County or State Board of Education. School sites. A new school site is provided in western Dublin. District boundaries.The jurisdictional issue over district service would need to be resolved. Police Protection The City of Dublin's police department would assume service responsibility for the Planning Area following annexation. Additional personnel and equipment will be needed to provide service for western Dublin. 2-5 A.N8914-SPIS914-SP2 Table:3 ' sand Ise a c� oust�g C aractertstxt 'G�estenc Uubu t Category Housing Units Total Acres Total % Ac.

A parking lot for use by transit riders is included near the proposed Schaefer Ranch Road interchange, with an area of about 1 acre. Neighborhood park.The Land Use Plan includes three neighborhood parks,with a combined acreage of 20 acres of level land which would qualify for the City's parkland dedication requirements. Neighborhood parks are discussed in detail in Section 7.2 of Chapter 7. Linear park.The Hollis Canyon Linear Park is proposed ds an east-west link across the Planning Area. A detailed description of this park is included in Section 7.8 of Chapter 7: Golf course. The golf course would occupy 175 acres. Included uses would be clubhouse recreation and commercial facilities in addition to the golf course itself. Detailed golf course standards are included in Section 7.3. Other open space. This primarily includes the Resource Protection Area described in Section 7.9 of the Specific Plan.Some areas of Internal and Perimeter Open Space(Section 7.5)are also mapped. The powerline easement is included in this category. 3.3 Development Proposals As noted in Chapter 1,there are two major development proposals in the Planning Area which are now under consideration by the City of Dublin. The Eden Canyon Country Club develop- ment includes properties controlled by the Eden Development Group and Schaefer Heights,Inc. The Cronin Ranch custom residential project is being proposed on the Cronin Property by Milestone Land Development Corporation.No development proposals have been made for the Morris property, a small inholding located in the southwest part of the Planning Area. Current development proposals are shown in Figures 3-2 and 3-3.In terms of the Specific Plan. these are considered as illustrative site plans only.The Land Use Plan(Figure 3-1)is the actual Specific Plan Map.Adoption of the Specific Plan does not mean the approval of the development proposals. These are subject to change based on EIR analysis and subsequent City staff evaluation throughout the development review process. Eden Canyon Country Club This project would be planned as a golf course-oriented residential community, with local commercial and other community facilities.Table 3-2 summarizes the current land use charac- teristics of the Eden Canyon Country Club. A maximum of 3,131 residential units would be included,with a range of dwelling types from large-lot single-family homes to townhouses and apartments.A golf course would occupy about 175 acres.The project would also include parks, commercial uses, a school site, fire station site, and some other minor public uses. More than 60% of the site would be retained in public open space. 3-4 A:\8914-SP8914SP31) Land Use and Housing ula�1 t` dI' talx :::;:.,::::::::>: r n `a B is an o :.<:> 'Z'able: .2, Suznmfi;.. often de tr.: : ...::..::...:...:..:..:P..::..::.....:..>::;:;:::;:«:>::::: .:::,::::..::,:::..,:::::................................

Figure 3-2 shows the applicants' current site plan.Adoption of the Specific Plan does not imply approval of this particular project. Figure 3-2 is included in the Western Dublin Specific Plan for illustrative purposes only,to show one possible way the site could be developed. In addition to their site plans, the applicants have submitted other project information to the City.Included are preliminary community design guidelines;preliminary landscape guidelines; conceptual sewer,water, and drainage plans, and a report on wastewater treatment alternatives. This information is available for review at the Planning Department in the Dublin City Hall. Cronin Ranch This project would include 125 residential homesites on 175 acres.The Cronin Ranch is located in the eastern part of the Planning Area, and is the only major landholding not integrated into the Eden/Schaefer Heights planning process in western Dublin. The applicant's current site plan (November 26, 1990)is shown in Figure 3-3.Again, it should be emphasized that adoption of the Specific Plan does not mean that this particular project is approved by the City. Figure 3-3 is included in the Specific Plan for illustrative purposes only, as one example of development that could occur on the site. Table 3-3 summarizes proposed land uses for this project.This plan has the following features: • 125 residential lots which would be sold by the applicant. A number of these lots would have slopes ranging up to 33 percent. Custom or production homes would be built on these lots. • Two access streets: an extension of Brittany Drive and a connection to a proposed street on the Hansen Hills property. 3-5 A:\8914-SP\8914-SP3D Land Use and Housing 3.4 Western Dublin Neighborhoods and Districts The Western Dublin Planning Area is divided into neighborhoods as shown in Figure 3-4. Each neighborhood has a distinct development character,which is described below.These neighbor- hoods are further divided into districts;each district has specific land use characteristics,which are noted in this section.Neighborhood and district characteristics are summarized in Table 3-3. These neighborhoods and districts are primarily described in terms of urban development and intensive recreational uses.Certain areas of graded slopes are included in the gross area of these neighborhoods and districts. Natural open space areas are discussed in Chapter 7. While a maximum number of units is noted, this does not necessarily mean that this is the number of units which would be approved by the City. Schaefer Heights Neighborhood (A) Strategically located near the Schaefer Ranch Road interchange, the Schaefer Heights Neigh- borhood is planned with an emphasis on pedestrian orientation.The Village Center is the focal point of this neighborhood,with a core of shops and a pedestrian plaza. Most housing planned in this area would be multi-family units. . District Al: Village Center Mixed-Use(11 acres). Land uses within this district would include the following. • Village Center Plaza:a minimum net one-acre landscaped town square,described in Section 7.6. • Village Center commercial: a maximum of 70,000 square feet 6f commercial space. • Residential units:up to 110 medium-high-density residential units. A number of these units may be upper-floor residential units over commercial or office uses. Because of the mixed-use qualities of this project, typical floor area ratios are not applicable. The Village Center concept is described in more detail in Section 3.6,with design guidelines in Chapter 9. District A2: Schaefer Hei1?hts Condominiums(9 acres).This area west of the Village Center is designated for medium density residential use,with a projected 100 units at a density of 11 units per acre.This location is at the edge of the visually-sensitive I-580 corridor. District A3: Schaefer Heights Townhouses(17 acres).Located northwest of the Village Center, this area is planned for a maximum of 230 townhouses on about 17 acres. District A4: Schaefer Heights Duets (26 acres). This area is planned for a maximum of 230 duplexes or "duets" at a density of about 9 units per acre. 3-8 A:\8914SP8914-SP3D Land Use and Housing • District C2• Machado Ride (78 acres).The golf course would wrap around this district of large-lot homes, with a maximum of 190 units. • District C3'Neto Ridge(65 acres).A maximum of 65 units along North Ridge Drive would overlook the golf course. • District C4: Hollis Ridge (9 acres). A maximum of 30 units would border the golf course on the southwest.The adjacent powerlines are a donstraint, as noted in Chapter 8., District C5:North Ridge Park (5 acres).A public neighborhood park is planned in the northern part of the Golf Course Neighborhood. Additional information about this park is included in Chapter 7. District C6• Machado Ridge Recreation Area (1 acre). A small private recreation facility is designated on Machado Ridge for the use of local residents. District C7• Skyline Ridge Residential(71 acres).This cluster,with a maximum of 231 homes would have a minimum lot size of 5000 square feet. District C8• Powerline Canyon Recreation Area(3 acres).A private recreation area is proposed along North Ridge Parkway, for the use of local residents. District C9' Skyline Ridge Recreation Area (1 acre). A small private recreation area is designated next to the Skyline Ridge Residential District. District CIO: Canyon Reservoir (17 acres). An area of 17 acres is designated for a proposed reservoir, which would be used in the wed recycled water system for irrigating the golf course,and other landscape irrigation. District C 11• Clubhouse Villas(13 acres).This area of proposed medium density residential use is planned for up to 130 medium-density residential units, with convenient access to the clubhouse facilities. District C12: Golf Course and Clubhouse (175 acres). This area would be used for the golf course and clubhouse facilities,including some commercial use.Issues regarding the golf course are discussed in Chapter 7. District C13: Fire Station (1 acre). This facility would be located at the intersection of North Ridge Parkway and Hollis Canyon Boulevard. District C'14• Elementary School (10 acres). A school site is planned between the Clubhouse Villas and Shell Ridge. District C15: Kelly Ridge Park (9 acres). A large neighborhood park is planned next to the school site. Detailed characteristics of this park are discussed in Chapter 7. 3-11 A:\8914-SP8914-SP3D Land Use and Housing visual impact. Height limits and setbacks are as stipulated in the City's H-1 (Highway Frontage)District, with a total maximum of 10,000 square feet of interior commercial space for all structures in combination. Maximum floor area ratio shall be 0.4. (2) Village center zoning.The City shall adopt a"Village Center Mixed Use" zoning ordinance and shall apply this ordinance to the area designated as the Village Center on the Specific Plan Land Use Map. This ordinance shall generally be based on the City's C-1 zoning district, except as noted in this section. ! Encouraged uses shall include medical and dental offices,cafes,bookstores,specialty shops,day care centers, and upper floor residential units.Permitted uses shall include general retail and office uses as noted in the City's.C-1(Retail Business)District,and hotels andinns not to exceed 30 units.Conditional uses shall include theaters and bars, and hotels and inns not to exceed 60 units.

Particular uses encouraged in this location are convenience retail stores(with controlled design),day care centers,restaurants,cafes,antique stores,art galleries,bookstores and other specialty shops. Permitted uses would include offices and general retail operations. Conditional uses would include bars and gas stations. » No front,side,or rear yard setbacks are specifically required for individual lots in the Neighborhood Center. Provisions for fire protection and access to light and air shall be subject to detailed design review.Interior commercial space shall not exceed 10,000 square feet.Maximum floor area ratio shall be 1.0.Residential uses are permitted above or adjacent to non-residential uses. 3.6B Precise Plan.-Village Center A Precise Plan shall be required for the Village Center at the time that a conditional use permit application are submitted for this site.This plan shall show detailed design features as noted in Chapter 9 of the Specific Plan. 3.6C Development Agreement It is in the interest of the City to provide a Neighborhood Center and Village <; Center, to meet basic needs of local residents. However, these mixed-use areas may not be economically viable until most of the proposed housing in the Planning Area has been completed. Consequently, the following provisions are necessary as part of the Development Agreement(see Chapter 11 for a discussion of the Development Agreement as part of the planning process). (1) Village e nt r.A site shall be reserved for the Village Center,if necessary,until substantial buildout of the Planning Area. (2) Neighborhood Center.A three-acre site shall be reserved for the Neighborhood Center if necessary until substantial buildout of the Planning Area. 3-17 A A8914-SP,S914-SM I Figure 3-5 i WESTERN DUBLIN LAND USE DISTRICTS A-1: mg.Cw"Wm.<bL6.

However, if unwarranted traffic signals or stop signs are used to reduce traffic speed,this could result in an increase in traffic accidents, air pollution, energy waste due to inefficient traffic flow, increased travel time, and a disregard of stop signs by drivers. Use of sequencing and demand-generated traffic signals can be helpful in promoting smooth traffic flow. Policy 4-3: Traffic signals and stop signs shall be installed at intersections that meet traffic signal or stop sign warrants. Traffic controls shall be kept to a minimum consistent with traffic safety needs. Current technology shall be used as needed to maximize responsiveness in traffic signals. Driveway Access For residential streets,direct access to the street and/or drivers backing onto the street generally do not present a major safety problem. However, as traffic increases, specifically in collector and arterial streets, direct access to the street from residential properties becomes increasingly hazardous,particularly in hilly terrain such as western Dublin. Policy 4-4: Residential driveways, requiring drivers to back onto the street, shall not be permitted on collector and arterial streets. Community Design Values of Streets Properly scaled streets can create more attractive communities and can contribute to neighbor- hood identity. Thoughtful alignment of streets can open up vistas that otherwise would have been blocked by closely-spaced homes. Policy 4-5: Streets shall be planned to enhance community design values, including human scale. Where possible,streets should be oriented to vistas of natural areas,public buildings, or parks. Street Pattern: Orientation and Identity In recent decades, the typical suburban street plan has consisted of a maze of curving streets, with no clear sense of hierarchy or orientation.This served to exclude through traffic from local neighborhoods. However,this also prevented the creation of a clear,legible circulation system, where neighborhood residents can understand how their home and street fits into the community. This problem is often apparent,for example,when someone is trying to locate a new address. Policy 4-6: Streets in western Dublin shall be designed to provide a clear sense of orientation and identity. 4-4 CAS914-SP\S914-SP4D Traffic and Circulation • A street would intrude on the regional trail corridor in this area. Policy 4-10: Dublin Boulevard shall be extended to connect West and Central Dublin. Due to difficult terrain, visual concerns, and possible effects on existing neighborhoods, no other general-use street links between West and Central Dublin shall be provided. Cronin Ranch Access Streets ; Two residential access streets would link potential development on the Cronin Ranch with central Dublin. These include an extension of Brittany Drive, and a second street leading from the Hansen Hills project. A preliminary review shows that physical capacity of existing streets is adequate to serve the maximum number of homes proposed on the Cronin site (125 homes). The added traffic will, however, increase traffic on existing streets where residents may be sensitive to this change in their neighborhood. Major grading would be required to construct these access streets. Policy 4-11: Plan the Cronin Ranch project to minimize effects on existing residential neighborhoods. Design streets to minimize grading. Emergency Vehicle Access Route (EVA) The Specific Plan does provide for an emergency vehicle access route (EVA) over Skyline Ridge. This road would also serve as a pedestrian link between the regional trail and Central Dublin, and as a possible utility access for a water line extending over the ridge. No general traffic would be permitted on this route. Flexible standards are needed to align this route over the ridge, including relative steep gradient, minimum width, and use of tight curves. These flexible standards would allow this route to be laid out with minimal grading, in contrast to a conventional street. Policy 4-12: An emergency vehicle route/pedestrian trail shall be included between West and Central Dublin. This route shall be planned to minimize grading and visual disruption of the ridgeline and upper slopes. Arterial Street: Hollis Canvon Boulevard This arterial street would serve as the main east-west street link in western Dublin. Hollis Canyon Boulevard would be designed as a moderate-speed parkway for efficient traffic flow. This arterial would generally follow an open space corridor, and would be designed for high visual amenity. Traffic on this boulevard would cross a bridge over Elderberry Canyon. Design features would include four travel lanes, bike lanes in each direction that include emergency parking space, a landscaped center median with left turn lanes at approved intersections, and landscape treatment on each side, with a meandering pedestrian path(see Section 4.4). 4-6 CA8914-Sn914-SND Traffic and Circulation Policy 4-13: Hollis Canyon Boulevard shall serve as the primary east-west circulation corridor in western Dublin. This boulevard shall be designed to provide an efficient and attractive route for private vehicles,public transit,pedestrians, and bicyclists. Major Collector Street: Dublin Boulevard Extension The primary purpose of this collector street is to provide a link between western and central Dublin. Dublin Boulevard is now planned for improvement to the approved Donlan Canyon project, and this street in rum would be extended to the vicinity of the potential Schaefer Ranch Road interchange.Dublin Boulevard would serve as a freeway frontage road,running just north of I-580. The alignment of this street would traverse steep terrain in a highly-visible location with some oak woodland. Nearly all of the frontage is designated as open space, with the exception of a small area of freeway commercial near the intersection with Hollis Canyon Boulevard. Policy 4-14: Extend Dublin Boulevard to western Dublin. Take all available and feasible measures to reduce grading and woodland removal for this proposed street. Residential Access Streets The purpose of residential access streets is to provide access to proposed homes, circulate localized traffic, and to distribute traffic between arterials or collector streets and residential units. This street classification is necessary to allow for the distinctive land use pattern of Western Dublin,where certain streets are needed to provide access to isolated residential areas. While these routes normally would be classed as collector streets, traffic volumes are lower than a typical collector street. Shell Ridge Road The purpose of this street is to provide access to proposed homes,circulate localized traffic,and to distribute traffic to and from arterials and collectors to residential units on the southwest slope of Shell Ridge.Alignment of this street is complicated by steep terrain.Detailed design measures would be needed to discourage speeding on this street, with its continuous downslope for a considerable distance.Major sections of Shell Ridge Road would pass through open space,with no residential frontage. The proposed alignment would require major grading in Hollis Canyon. Policy 4-15: Provide Shell Ridge Road as an access route to residential units at the base of Shell Ridge.Design this street to minimize grading and to reduce speeding potential. North Ridge Drive and Skyline Ridge Drive These proposed streets circulate local traffic, and distribute traffic from collectors and arterials to homes around the golf course and along Skyline Ridge. Much of the length of these streets would have open space on one side, affording opportunities for motorists and pedestrians to enjoy views of the ridgelands. The middle sections of these parkways are expected to have low 4-7 CA8914-SP8914-SND Traffic and Circulation traffic volumes; they would have higher traffic volumes more typical of a collector street near their intersections with Hollis Canyon Boulevard. These parkways are designated for future use as transit,pedestrian and bicycle routes. Policy 4-16: North Ridge Drive and Skyline Ridge Drive shall be designed to take maximum advantage of open space views. Qther Local Access Streets Morris Property Access Special consideration is needed for access to the Morris property. One to four residential units are anticipated for this site. The access to this property is located in the proposed Hollis Canyon Linear Park. The access street would need to follow the alignment of the existing drive serving the Morris residence;widening of this drive is limited by steep slopes on the north and Blackbird Pond on the south. Policy 4-17: Plan the Morris property access for joint use of the pavement by low-speed vehicular traffic and bicycles. Local Residential Streets In recent decades, residential streets have often been viewed only in terms of their function in providing access and conveying traffic.However,residential streets also provide a visual setting and entryway for homes. It is important to design a residential street not just as a part of the transportation system,but as a vital part of a residential community's living environment. Traffic safety is a vital consideration for residential streets. A variety of measures are available for controlling traffic speeds to improve safety on local residential streets. Chokers and road narrowinz. This refers to treatment of the roadway to produce a narrower passageway.This can be'accomplished both physically and perceptually. A physical approach would include narrowing roadway widths at intersections by striping, providing mid=block landscaped medians that force drivers to slow down in passage,and narrowing lanes on straight street segments. With a perceptual approach, landscaping would be used that creates the impression of a narrow roadway.Overhanging trees,low hedges at the roadway's edge and trees or shrubs planted close to the edge of the roadway can all be used. Care must be taken not to obstruct the drivers' view of children. In all cases, careful consideration is needed for maintenance (street sweeper access) and drainage. Stop i-r1 . The purpose of stop signs is to assign right-of-way at intersections with significant volumes or safety problems.All-way stop control is not a desirable means of reducing general traffic speeds as they typically affect travel speeds only in an area within approximately 200 feet of the intersection. 4-8 C:\8914-SPS914-SND Traffic and Circulation Sneed limit signs. These devices are generally effective only with intensive enforcement. Policy 4-18: Use various techniques such as street alignment, short street length, strategic narrowing of lanes,and pavement striping,in order to promote traffic safety on local residential streets in western Dublin. ACTION PROGRAM: Streets and Highways 4.2A Detailed development plans submitted to the City shall include the standards noted below. Localized exceptions for special conditions may be approved by the Public Works Director in keeping with City procedures.

All= • Travelled way:20'minimum(no parking),one way;24'for two-way traffic. • Access:unlimited,consistent with traffic safety. • Adequate backup space shall be provided to the satisfaction of the Public Works Director Other Local Access Streets • Provide access to Morris property,coordinated with recreational uses in this area. Size and design shall be approved by Director of Public Works. • Verify that satisfactory access is provided to existing rural residences to remain. Intersections • The angle between centerlines of intersecting streets shall be as nearly right angles as possible. Streets shall intersect only in tangent sections. The tangent length shall extend a minimum of 100 feet with a 4-10 C:\8914-SR8914-SP4D Traffic and Circulation maximum grade of 6 percent from the point of curb return(PCR)on each leg of the intersection. The tangent length of 100 feet is not required for a residential street intersecting another residential or collector street if an adequate intersection sight distance is provided. Exceptions to this intersection standard may be granted by the Public Works Director where special conditions are present. Emergency Vehicle Access • Provide an emergency vehicle access route between the Eden Canyon Country Club and the Cronin Ranch developments. This route shall meet basic standards for emergency vehicle use, including minimum width,minimum radius curves,maximum gradient,and durable surfacing.Construction shall be carefully planned to minimize grading and visual impact. 4.2B. Eden Canyon Road Interchange. Provide lane widening and other improvements as needed for satisfactory interchange operations. Geerdinate wefk with GaRfafts-. Continue the project development process with Caltrans. 4.2C. Schaefer Ranch Road t r h n . The City shall continue investigation and planning the project development process for a new interchange at Schaefer Ranch Road,in cooperation with Caltrans. 4.3 Public Transit Currently,no transit lines directly serve the Planning Area.The Tri-Valley,however,is served by local bus service and BART express bus service. Figure 4-8 illustrates possible public transit routes in western Dublin,although actual alignments may vary once development occurs. In planning for future public transit in western Dublin, it is important to look at land use patterns as well as bus route alignments.Apartments,shops,and offices clustered around a transit stop can help to encourage people to use the bus. ---------------------------------------------------------------------------------------------------------------- GOAL: Create opportunities for public transit use in western Dublin by providing convenient bus service and by clustering key land uses around transit stops. ---------------------------------------------------------------------------------------------------------------- Access to Rapid Transit System The Bay Area Rapid Transit District (BART) is actively planning an extension which would follow the center median of I-580 along the south side of the Planning Area.No station is planned in the immediate vicinity of western Dublin. However,BART express bus service is currently provided from central Dublin to several BART stations. One way to promote the use of BART and its express buses is the provision of park-and-ride facilities. Generally, they are provided at freeway interchanges and other key transfer points. Design criteria include convenience to the freeway,visibility from the freeway,location within 4-11 0\8914-SP8914-SND Figure 4-2 CIRCULATION PLAN Streets & Highways i LEGEND i EXISTING PROPOSED �■ Arterial .. .. , .... � .. ....K.. ——- Major " .

SEWER, WATER AND DRAINAGE This Chapter includes policies and action progranig for water supply, wastewater, and storm drainage for western Dublin. A more detailed description of existing facilities and current District boundaries is included in Western Dublin Report 1.1 5.1 Domestic Water System Only a small portion of the Western Dublin Planning Area is currently served by domestic water agencies. The East Bay Municipal Utilities District(EBMUD)currently serves several residen- ces along Eden Canyon Road. The Western Dublin Planning Area also lies paiiiaHy wit outside the Dublin-San Ramon Services District (DSRSD) which provides water to both Sftn Ramen ftnd Dublin. In order to serve potential future populations,DSRSD would expand its existing boundaries and infrastruc- ture. Figure 5-1 illustrates a conceptual water supply plan for western Dublin. With the standards of this Specific Plan,an adequate water supply will be available for the projected uses in western Dublin. ---------------------------------------------------------------------------7------------------------------------ GOAL: To insure dernesfie potable water supplies are sufficient in quality and quantity for demestie eensumption and fire suppf ession residential, commercial, and fire suppres- sion demands in Western Dublin, and to provide for conservation and recycling of water resources. ---------------------------------------------------------------------------------------------------------------- Pressure Zones The DSRSD distribution system currently has three pressure zones. (Zones 1,2 and 3). These zones handle water service needs below the elevation of 740 feet. 1 WPM Planning Team,Inc.,Study Report 1:Environmental Setting/Planning Considerations.Westem Dublin General Plan Amendment/Specific Plan Study.Dublin,CA, 1989.Available for review at the Planning Department,City Hall. 5-1 A.-W14-SP8914-SM Sewer,Water and Drainage Expansion of the existing pressure Zone 3 will be necessary to provide a trunk line connection and completion of a loop system. Because several portions of the Planning Area proposed for development are located at higher elevations,two additional pressure zones,Zones 4 and 5,will be necessary. The new zones would be required to improve water mains, pumping facilities and storage tanks (See Figure 5-1). Policy 5-1: Provide an adequate water supply system and related improvements and storage facilities to meet DSRSD standards. iet Emp knsieft Water Service and Rate Structure The DSRSD is aetively seeking to eRp de not-inebade et seetien�The Planning Area deng Eden Ganyon Read is currently outside DSRSD boundaries. Treated water is supplied to DSRSD by the Alameda County Flood Control and Water Conservation District, Zone 7. Zone 7 estimates that it currently has a sufficient total water supply for its service area through the year 2000. This is based on growth rates projected by the cities within the Zone 7 service area. Most of the Planning Area is included in Zone 2 of the Alameda County Flood Control and Water Conservation District. Zone 2 has not historically been a purveyor of water. There are institutional issues which would need to be resolved if Zone 7 were to supply water within Zone 2 boundaries. Various mechanisms to resolve this issue may be available, such as annexation of the Planning Area to Zone 7. Since most of the Planning Area is included in Zone 2, inter-zone coordination is needed. The Dublin San Ramon Services District has stated its intent that existing residents of Dublin should be protected against the costs of new development as reflected in water-associated expenses. A memo from the District states that the costs of new development, whether as connection charges or monthly service charges, should not become a burden on the existing ratepayers. A tiered or additional fee can be imposed as necessary on new developments due to the costs of securing new supplies for them. Policy 5-2: Encourage DSRSD to expand the District's service boundaries to encompass the entire Western Dublin Planning Area. Water supply system expansion should be coordinated with the water purveyor (Zone 7). The City shall support Zone 7's and DSRSD's capital improvement program and water management plan,as it relates to the Western Dublin Planning Area. 2 Bert Michalcryk,Technical Services Manager,DSRSD,Memo to City of Dublin Planning Commission, February 18,1992. 5-2 k\8914SPIS914-SP5D Sewer,Water and Drainage The City of Dublin shall encourage and support DSRSD in its efforts to protect existing water users from the costs of new development, including the possible use of tiered or additional fees and adjusted water connection charges,for new users in Western Dublin.

The DSRSD Water Use Reduction Plan, as amended or replaced by provisions of the Urban Water Management Plan and amendments,shall be supported by the City ofDublin.The DSRSD Urban Water Management Plan and amendments are planning documents that are intended to give staffand policy makers guidance and ready information as they manage the water utility. The DSRSD Water Use ReductionPlan is part of the District's code. Conditions of approval shall be added to the project which effectively serve to implement elements of the Water Management Plan relative to water conservation, including but not limited to the following: • Water efficient irrigation systems within public rights-of-way,median islands,public parks recreation areas,and golf course areas. X. • Drought resistant plant palettes shall be used in common areas. • Recycled water systems shall be provided to park,recreation, and golf course areas in conformance with a recycled water site development plan to be prepared by the developer and approved by the City, DSRSD,DONS and other necessary authorities. 5.1B DSRSD Standards. The City shall require that design and construction of all water system/facility improvements be in accordance with DSRSD standards. 5.1 C Pressure Zones.As a condition of development approval,the City of Dublin shall require that pressure Zone 3 be expanded and two additional pressure zones and water storage facilities be created. These zones will be designed to service development areas between elevations of 740'-1000'or above.The requirements of DSRSD will dictate the expansion of pressure zones and their elevations.Elevations of Zones are subject to revision when facility design is finalized. 5.113 �erzia} Individual Proiect Service.The City shall verify that adequate water service is available for each proposed project in the Planning Area. 5.1E E,,V t ne Wells.The City, in coordination with DSRSD,shall enforce the requirement to connect with the domestic potable water system and abandon the wells as theprimary household use where this is feasible. 5-3 A:\8914-S"914-SM Sewer,Water and Drainage Wells may be allowed to operate for existing residences,subject to health requirements,and provided that water from the private well is used only for the parcel on which the well is physically located. 5.2 Wastewater The Planning Area is not currently serviced by a municipal sanitary sewer system. Future development in the Planning Area would be served by the Dublin-San Ramon Services District (DSRSD), since this district currently includes most of the Planning Area. A conceptual wastewater plan is shown in Figure 5-3. This Specific Plan includes standards to assure that adequate wastewater service would be provided for western Dublin. ---------------------------------------------------------------------------------------------------------------- GOAL: To provide satisfactory wastewater collection, treatment, and disposal for western Dublin. ---------------------------------------------------------------------------------------------------------------- Wastewater Facilities and Services At present, the extreme western edg the Planning Area is not within the current district boundaries and would require petition/annexation into the district, as noted in Section 5.1. Sanitary sewer service to the Planning Area is constrained by the lack of off-site downstream wastewater collection facilities, the capacity at the existing treatment plant in Pleasanton, and the capacity in the existing export pipeline. Shies ere undem-ay by the DSRSD and 9*z�k to empand eapfteiti DSRSD has been a participating member in a TWA project to provide adequate treatment and disposal capacity for its advance planning areas, including Western Dublin. Policy 5-3: Provide public wastewater collection and treatment for all new development in the Western Dublin Planning Area. Wastewater Reelamati Recycling: Eden Canyon Country Club For the Eden Canyon Country Club, an alternative to exporting project generated treated wastewater into the sanitary sewer system would be to use recycled wastewater for irrigation needs,such as street medians,the golf course and common landscaped areas within the Planning Area. A reeletimed recycled water distribution system, parallel to the conventional domestic water system, could be installed containing pumping, distribution and storage facilities. An on-site 5-4 A:\8914-SF 8914-SP5D Sewer,Water and Drainage reservoir would be provided to store teftiapy treated effluent during the winter season when irrigation demand is low. Figure 5-3 illustrates a possible configuration of facilities to provide reclamation of wastewater. Policy 54: Promote alternative tertiary recycled wastewater treatment and use in western Dublin, to provide an alternative water source for irrigation of landscaped areas. Expansion of Facilities: Current capacity of the export pipeline for treated wastewater will need to be expanded unless alternate uses for treated water are utilized. Policy 5-5: Veirt)3 Require that wastewater treatment facilities are provided as needed to meet the needs of figure development in western Dublin. Cronin Ranch Wastewater Service- Unlike the Eden Canyon development,the Cronin Ranch project is located near existing sanitary sewer lines. A service line is planned along Martin Canyon. At this time,this project could be served by existing collection and treatment facilities. Policy 5-6: Extend existing wastewater service lines to serve the Cronin Ranch project. ACTION PROGRAM: Wastewater 5.2A Export Pil2eline•The City of Dublin shall continue to consult with the Tri-Valley Wastewater Authority (TWA)and its current efforts to explore the feasibility of a new wastewater export pipeline system,which would impact the western Dublin area. 5.2B Wastewater Collection System Master Plan.The City shall request DSRSD to update its wastewater collection system computer model to reflect the revised land use alternative for western Dublin. 5.2C Design-Level Wastewater Investigation.The City shall require western Dublin proponents to prepare (in coordination with DSRSD) a detailed wastewater capacity investigation to supplement the information in the Specific Plan,which reflects the phased development approach matched against the allocation of sewer permits. 5.2D IIse of Raals3i Recycled Water. watef system lestem Dublin Pi area.In additieft, the City shaR request --e updating of the -er the b the Western Dublin P1eBftiftg-Ade&.Recycled water shall be provided to park, recreation,and golf course areas in conformance with a recycled water site development plan to be prepared by the applicant and approved by die City, DSRSD, DOHS, Regional Water Quality Control Board, and other necessary authorities. 5.2E Annexation of Seriice A_reahnter-Zone A_mngemmeents. in the b Areft to be afoexed to _DSR.SD, in er-def to The City shall require proposed 5-5 k\8914-SP8914-SM Sewer,Water and Drainage development in the Planning Area to be annexed to DSRSD and included in the DSRSD sphere of influence, in order to provide sanitary sewer service: 5.2F improvement Standards.The City shall require wastewater systems to be designed in compliance with DSRSD standards and guidelines.These guidelines should include but not be limited to the following: • Fencing as needed for Powerline Canyon Reservoir. • New wastewater network should be designed to be placed within the street rights-of-way. • Where necessary,easements should be acquired for wastewater lines within private property areas. • Wastewater network should utilize gravity lines where feasible. 5.2G C—renin4�Individual Proiect Service.Before final subdivision map approval,the applicant shall provide documentation to the City that satisfactory sewer service can be provided to the Grenin Rm each proposed project in the Planning Area. 52H Financing. As a condition of project approval, the City of Dublin shall regtdre verification that financing arrangements for wastewater facilities are satisfactory. XXX 5.21. F_xisti>EggDtic Tanks.The City shall coordinate with DSRSD regarding the use of existing septic tanks in the Planning Area. The City shall encourage DSRSD to allow continued use of septic tanks,subject to health requirements, where there would be a hardship on the part of existing property owners. As an alternative,the City shall considerphasing of annexation so that the Morris property is not initially annexed and subject to DSRSD hookup requirements. 5.3 Drainage and Water Quality The Western Dublin Planning Area lies within Alameda County Flood Control And Water Conservation District Zone 2 and on the western edge of Zone 7.The Planning Area is bisected by several major valleys and swales where runoff water is collected and ultimately discharged into San Leandro Creek. Eighty percent of the Planning Area drains primarily into Hollis Canyon drainage basin, while the remaining 20% drains into either the Eden Canyon drainage or the Dublin Canyon watershed basin.A conceptual storm drainage plan for western Dublin is shown in Figure 5-4. B aced on FEMA maps, the Planning Area is not subject to substantial flooding hazards. Future site runoff from natural and urban areas could be contained in detention basins with capacities to accommodate peak runoff flows. The Specific Plan includes standards to provide satisfactory storm drainage facilities for the projected land uses of westem'Dublin. ---------------------------------------------------------------------------------------------------------------- GOAL: To provide adequate storm drainage facilities for the Western Dublin Planning Area at an urban level to service the new development of western Dublin. ---------------------------------------------------------------------------------------------------------------- 5-G A.\8914-5 P\8 914-S P5D Sewer,Water and Drainage Alteration of Existing Drainage Patterns Development of the Planning Area will change existing drainage patterns with the potential of increasing erosion and flooding. Various other environmental concerns associated with grading of drainage channels are discussed in Chapter 8. Policy 5-7: Require drainage design standards thatwill minimize any increased potential for erosion or.flooding. Require applicants to demonstrate that proposed projects would avoid any net increase in runoff leaving the site. Water Quality The Planning Area and other uphill areas which drain onto the Planning Area consist of natural grasslands with scattered oak trees.The primary use of this area consists of cattle grazing.Some contaminants may result from livestock wastes. However, this most likely does not cause significant degradation of runoff quality. There are a few existing homes within the Planning Area. These residential uses produce additional pollutants including trash,herbicides,pesticides,oil and metals from motor vehicles. Development of western Dublin would result in severe limitation of livestock grazing on site, although proposed open space areas could support limited grazing. Grazing may continue in off-site areas which are upstream and downstream of the site within the same watershed; in this case,livestock wastes would continue to affect the quality of runoff in the Eden,Hollis and San Lorenzo Creeks. However,the concentrations of urban runoff pollutants,including oil, grease, herbicides, pesticides, litter and metals, can be expected to increase and could affect runoff quality. On the other hand, project development plans would include significant open space, watershed,and pollutants produced by the project would be diluted by runoff from undeveloped and landscaped areas. Policy 5-8: Plan facilities and select management practices in western Dublin to protect and enhance water quality. Alteration of Existing Streams A number of intermittent stream channels are now located within the Planning Area, with significant environmental qualities as described in Chapter 8.Drainage facilities associated with development in western Dublin could have an adverse effect on these existing streams and associated riparian vegetation. Policy 5-9: Plan drainage facilities in western Dublin to minimize adverse effects on existing stream channels and riparian vegetation. 5-7 A.\8914-SP8914-SM Sewer,Water and Drainage ACTION PROGRAM: Drainage and Water Quality 53A Master Drainage Plan. The City of Dublin and the Alameda County Flood Control and Water Conservation District shall require a Master Drainage Plan to be prepared prior to development approval. The plan shall include: • Hydrologic studies of entire related upstream watersheds. XXX • Phase approaches and system modeling. • Documentation of existing conditions. • Design-level analysis of the proposed development on the existing creek channels and watershed areas. • Detailed analysis of effects of development to water quality of surface runoff. • Detailed drainage design plans for each phase of the proposed project. • Documentation that any net increase in runoff leaving the site shall be avoided. • Design features to minimize runoff flows within existing creeks/channels in order to alleviate potential erosion impacts and maintain riparian vegetation. 53B Flood Control. The City of Dublin shall require development in the Planning Area to provide facilities to alleviate project exacerbation of downstream flooding.These facilities shall include: • Retention/detendon facilities to control peak runoff discharge rates. • Energy dissipators at discharge locations to prevent channel erosion, as per Alameda County Flood Control and Water Conservation District guidelines. Energy dissipators should be designed to minimize adverse effects on biological resources and the visual environment; in particular, widespread use of rip-rap should be avoided. 53C Water Quality Investigation . A specific water quality investigation shall be required in order to demonstrate existing water quality and impacts that urban project runoff would have. The water quality investigation shall address the quantity of runoff and the effects from discharged pollutants from surface runoff into creeks and detention facilities. 53D Coordination with Other Agencies. • Modifications or enhancements to creeks or the abutting riparian area need to be coordinated with the required permitting agencies as necessary.(California Department of Fish and Game and/or U.S.Army Corps of Engineers.) • A State Water New Development permit will be required from the State Water Resources Control Board. 5-8 A.-V914-SP8914-SM Community Services and Faci' needs. School sites shall not be adjacent to arterial streets. Provide a drop-off and pick-up area. Financing of School Improvements Purchases and construction of new schools are a constraint to school districts, given the restrictive State school programs and lack of financial backing. Policy 6-2: In conjunction with the applicable school district, project applicants should cooperate in providing new school facilities through dedication andlor developer fees. ACTION PROGRAM: Schools 6.1A School District Boundary. Provide assistance to help resolve the issue of attendance areas between Castro Valley School District and Dublin Unified School District. 6.1B Schools. As a condition of project approval, the City of Dublin should require that a logical and buildable school site is offered for dedication according to the State's Board of Education guidelines and acceptable to the local school district which will serve the Planning Area.The City shall coordinate efforts with the school district to require fees or construction of facilities. • Where feasible,the proposed new school(s)should be designed for other community functions,such as a library and multi-purpose rooms. • In coordination with the City of Dublin,the school site should be located adjacent to proposed City parks,where feasible. Also,the school improvements should be designed to integrate with the adjacent park use. However,schools and parks should be able to operate independently,and school acreage shall not count toward park acreage. • Support the efforts of the school district in financing the proposed school construction,either through application of dedication of school site(s)or the participation of alternative financing methods,such as Mello-Roos district and general obligation bonds. 6.2 Police Protection The Planning Area's police protection services are currently under the jurisdiction of the Alameda County sheriff's department. The City of Dublin's police department would assume service responsibility of the Planning Area following annexation of western Dublin to the City. The City's police department is a division of the County sheriff s department and is funded by the City via .a contractual,agreement between the City of Dublin and the County of Alameda. The City of Dublin owns the police department's facilities and equipment but the police department personnel are employed by the County sheriff's department. The City's police 6-2 A:\8914-SP�8914-S P 6D Community Services and Facilit' This facilitates the sharing of staff and equipment among the fire districts within specific zones in case additional resources are needed in an emergency. Once the City annexes the Planning Area, the Dougherty Regional Fire Authority (DRFA) assumes responsibility for providing fire protection services to the Planning Area. The DRFA is currently a joint powers authority operated by the Cities of Dublin and San Ramon,and serves the entire City of Dublin and only a portion of San Ramon. The Planning Area is considered a medium fire hazard in general. The level of hazard is determined by several factors such as weather,intensity of fuels,topography,access to the area, and the use of the area. Sparks from motor vehicles and arson have been the principal reasons for fires in the area over the years. ---------------------------------------------------------------------------------------------------------------- GOAL: Provide adequate fire suppression equipment and facilities to service develop- ment in the Western Dublin Planning Area. ---------------------------------------------------------------------------------------------------------------- Fire Insurance Rating/Response Time The DRFA currently has a state Insurance Services Office(ISO)rating of three. The ISO rating is a measure of risk to assess liability for insurance purposes. The fire authority maintains this low rating by responding to calls for service within five minutes and strategically locating fire stations within one and one-half miles from developed areas. The five minute response time and the 1.5 mile zone are criteria which would need to be met in order to preserve the low risk rating,unless special provisions are required for new construction outside this limit. Location of the Planning Area places it outside the 1.5 mile zone and 5 minute response time needed in order to meet the state ISO rating of three. Policy 6-4: Provide additional facilities so that all new development within the Western Dublin Planning Area generally is within a 1.5 mile radius of afire station facility, and capable of being reached within 5 minutes. Require fire sprinklers and other special requirements for any homes outside this limit. Wildland Fire Hazard - As development occurs in the Planning Area, easier access to rural open space areas could increase the chance of fire due to vandalism or carelessness. This increased fire hazard can be counteracted through appropriate design measures, such as the use of noncombustible roof materials. In addition, access can be controlled to reduce fire risk. Policy 6-5: Minimize fire risk by controlling access, establishing building and planting design standards and maintaining open space areas.Integrate with plans in adjoining areas protected by the San Ramon Valley Fire Protection District. 6-4 A.\8914SM914-SPED Community Services and Facilities ACTION PROGRAM: Fire Protection 6.3A Fire Facilities.The City shall require additional fire facilities to be logistically built,staffed,equipped and maintained,according to Dougherty Regional Fire Authority(DRFA)criteria and guidelines.Incorporate fire department recommendations regarding design aspects of development that affect access,waterpressure, fire safety and prevention in the Western Dublin Planning Area into the requirements for project approval. 63B Design Standards.The City shall require that the following DRFA design standards are incorporated, where appropriate: • Nee-eambustible Class 'A"roof material in all new construction.Wood shingles and shakes shall be prohibited • Capacity of 1,000 GPM at 20 PSI fire flow from project fire hydrants on public water mains. For groupings of one-family and small two-family dwellings not exceeding two stories in height and more than 30 feet apart,the fire flow requirements are a minimum of 1000 GPM. Fire flow requirements for all other buildings will be calculated based on building size,type of construction,and location. • A buffer zone along the backs of the homes which are contiguous with the wildland area. This buffer zone is to be landscaped with irrigated(wet banding)or equivalent fire-resistive vegetation. • Automatic fire alarm systems and sprinklers ia ftH aea residential stmetules for humae use. where required by current codes. • Compliance with DRFA minimum road widths,maximum street slopes,parking recommendations,and secondary access road requirements. • Require residential structures outside the Authority's established response time and zone to include fire alarm systems and sprinklers. 6.4 Solid Waste Coordination of solid waste management activities in Alameda County is the joint responsibility of the County's Solid Waste Management Authority and local jurisdictions. The City of Dublin currently contracts with a private company for residential and commercial garbage collection within the city limits. This disposal service company does not foresee any problems in providing garbage collection service to the Planning Area once it is developed. ----------------------------------------------------------------------------•----------------------------------- GOAL: Development in the Western Dublin Planning Area shall provide efficient collec- tion of solid waste material with special emphasis on recycling programs. 6-S AM914-SPIS914-SPED Community Services and Facilities 6.5D Public Library Service,The City should coordinate efforts with Alameda County to provide library services,including the following options: • Bookmobile service in western Dublin. • Possible community use of the school library in western Dublin. • Possible assessment of fees for branch library expansion in downtown Dublin. 6.5E Commute Organizations • The City shall require a minimum one acre site,with suitable access to a collector street,to be reserved for sale to nonprofit organizations which would allow significant public access to meeting space.The sales price of this property shall be reasonable,and the City shall be notified of the amount.This land shall be reserved in a location approved by the City,where the facility can serve as a local landmark. This land shall be reserved until substantial buildout of the Planning Area as determined by the City, and may revert to private park and recreation use with the approval of the City. • Residential zoning in western Dublin shall include community organizations as a conditional use. 6.5F The City shall analyze other municipal service needs to assure that satisfactory ongoing service can be provided for western Dublin. This includes building and safety, engineering, planning, and general government services. 6-9 AA8914-SP�S914-SPED T 7 ec1restton:::a> d o e .acs Qwnersh�p end M t em x > <:>:»>< Text Loca. % of Management Ongoing tion in Type of Total and Funding SP Open Space Acres Site Access Ownership Maintenance Source 7.2 Neighborhood 20 <1% Public City of Dublin City of Dublin City revenues Parks Parks and Rec.

Maintenance of this buffer zone shall be the responsibility of a Homeowners'Association or other entity approved by the City. The buffer zone should have a minimum width of 50 feet,and shall include all engineered slopes and drainage structures. 7.6 Village Center Plaza The Village Center will serve as the social and commercial center of western Dublin.The Village Center uses would be grouped around a plaza,modeled after the traditional town square as seen in Sonoma and elsewhere. The Village Center concept is discussed in Chapter 3, with design standards in Chapter 9;this section focuses on the central open space within the Village Center. -------------------------------------------------------------------------------------------------------------- GOAL: To include open space in the Village Center which will serve as a setting for outdoor events and socializing. ---------------------------------------------------------------------------------------------------------------- This open space would be designed for outdoor events such as arts and crafts exhibits, educational and public service displays, holiday events, and small concerts. The plaza would not be used for organized sports.Maintenance would be handled as part of the management of the Village Center. Policy 7-15:As part of the Village Center,provide a plaza with a minimum size of one acre, designed as a traditionally-oriented town square for outdoor events. ACTION PROGRAM: Village Center Plaza 7.6A As part of detailed development approval for the Village Center,the City shall require.a landscaped open space area of one acre or more.The plaza shall include lawn,canopy shade trees,seating areas,lighting, and landscaping,with space designed for exhibits and outdoor events. 7-10 A:\8914-SP8914-SP7D Recreation and Open Space Staging Area In conjunction with the regional trail, a staging area is needed for area residents to use the trail. The staging area shall be conveniently located for visitors to western Dublin,without having to travel through residential neighborhoods. A possible location would be at the northeast corner of Dublin Boulevard and Hollis Canyon Boulevard; Dublin Boulevard would need to be shifted slightly south in order to make room for parking. Allowance is needed for equestrian trail users. Policy 7-17: Provide a staging area for trail users in western Dublin,with convenient access for visitors. Lateral Trail Links and Trail Access Points As described in Chapter 4,lateral trail links should be provided to connect residential areas with the regional trail. Where development occurs near the trail, access points should be included for the use of local residents,with orientation signs,benches, and on-street parking space. Policy 7-18: Lateral trail links and trail access points to the regional trail shall be located and designed for convenient pedestrian use. Possible Connection to West and North As noted in Section 7.8,a linear park is planned in Hollis Canyon,extending across the Westem Dublin Planning Area from east to west. An extension of this pedestrian route to the west would be highly desirable, although intervening streets and freeways present complications. This link could serve pedestrians walking to Castro Valley destinations,as well as providing a recreational trail link to the primary regional trail in Castro Valley.Links to the north could connect with a planned trail system in the Westside area of San Ramon. Policy 7-19: Encourage pedestrian links between western Dublin and nearby urban areas. In particular, explore the creation of a pedestrian link between the Planning Area and Castro Valley,and trail links with the San Ramon Westside Area. ACTION PROGRAM: 7.7A The City shall require the following as conditions of development approval: • Dedication of the regional trail corridor along Divide and Skyline Ridges,as well as a staging area and links to the San Ramon Westside Area,to the East Bay Regional Park District or other approved entity. • Construction of trail as well as staging area improvements according to EBRPD standards. Trails typically are 12 to 14 feet wide,with a 10 percent slope,preferable maximum. Twelve parking spaces shall be provided,including at least three spaces for equestrian truck-trailer units. Adequate turnaround space shall be provided for truck-trailer units. 7-12 A.\8914-SPM 14-SPM Recreation and Open Space ACTION PROGRAM: Hollis Canyon Linear Park 7.8A Park Planning. The City of Dublin shall determine the preferred concept of park ownership and management for the park,and shall require the following as conditions of development approval.An interim agreement may be needed with the Moms property owners to clarify access across this property. • Provide funds for the City to prepare a detailed park plan,including standards and construction drawings for trails,fencing,pond modifications,and other necessary alterations. • Dedicate land. • Conduct a complete geotechnical investigation of all potential park land, and complete any necessary landslide repair which could affect trails or other improvements. • Complete stream channel and pond improvements as described in Chapter 8. • Provide complete revegetation plans as needed in park corridor. This would include enhancement of existing vegetation, as well as new plantings in areas to be disturbed by grading. 7.8B Park Improvements. • Construct bicycle path and pedestrian trail. • Complete stream channel and pond improvements. • Make special provisions to minimize impact of the linear park on the existing Morris residence.Phase the project if necessary so that the linearpark in this area is installed after most development is in place. Confine access to the immediate corridor of the trail in this area, which generally would follow the existing alignment of Hollis Canyon Road.Require secure fencing to minimize the risk of trespass. 7.9 Resource Protection Area This comprises the large areas of natural open space in the Planning Area, including ap- proximately 1,900 acres.Most of the Resource Protection Area is rugged terrain in the eastern part of the Planning Area; Shell Ridge,northern Oak Ridge, and Phillips Ridge would also be included. Detailed environmental issues involving resource protection are discussed in Chapter 8; this section focuses on access, ownership, and management responsibilities. ---------------------------------------------------------------------------------------------------------------- GOAL: To designate large areas of natural open space in the Planning Area as a Resource Protection Area, in order to preserve this land as permanent natural open space. ---------------------------------------------------------------------------------------------------------------- 7-15 A.V914-SPN8914-SP7D Recreation and Open Space Policy 7-22: The City shall encourage the East Bay Regional Park District to take on management of the Resource Protection Area. Any other entity responsible for management shall have the necessary expertise for managing large tracts of open rugged terrain. Access The proposed Ridge Trail and its lateral trails would be located in the Resource Protection Area. Other general public access to these biologically-sensitive lands would need to be restricted. Emergency and maintenance access,primarily for fire control and geologic hazard abatement, is needed along the development perimeter. Policy 7-23: Restrict public access in the Resource Protection Area to trails and related low-intensity recreational use. Provide access to the Resource Protection Area as needed for fire control,geologic hazard abatement,and general maintenance. ACTION PROGRAM: Resource Protection Area 7.9A The City shall require the following as conditions of approval: • Land dedication. pttbRe e--*,., .....fmefit a en spaee.�Ibe dedieatien agreement sh—all efnphasi2e 14iat this land mey not be eemidered f Land designated as a Resource Protection Area shall be restricted to open space by documents which shall emphasize that this land may not be considered for development in the fixture. • Management.Resolution of the open space management issues must be completed prior to the issuance of site-specific development plans and/or grading plans. • Maintenance.Arrangements for long-term maintenance by the East Bay Regional Park District or other entity shall be specified to the satisfaction of the City. • Access. For maintenance and fire protection purposes, access shall be provided at frequent intervals along the perimeter of development,as approved by the Fire Chief. 7.9B The City shall establish an open space zoning district with the following provisions,or take equivalent action: • Allowable uses shall be limited to wildlife habitat,watershed, general resource management,low-in- tensity recreational use(trails)and existing powerlines and communications facilities. • High intensity lighting,major noise-producing operations,or other activities which would degrade the resource and esthetic value of natural open space use shall be prohibited. • Agricultural use shall be restricted to any controlled grazing,which is part of a wildfire management program. • Grading shall be limited to necessary initial earthwork completed as part of adjacent development;minor grading for trail improvements;driveways for existing homes; and landslide repair or other necessary 7-17 AA8914-S P,S914-S P7D Recreation and Open Space geologic hazard abatement near development.New landslides which do not affect development or roads may be left in place. ---------------------------------------------------------------------------------------------------------------- 7-18 A:\8914-M8914-SP7D Environmental Management Policy 8-10: Development of the Western Dublin Planning Area shall include measures to effectively minimize the problems associated with springs and shallow ground water conditions. Excavation Deeper cuts in areas underlain by bedrock of the Panoche Formation,Monterey Group and the San Pablo Group may expose rock that is difficulf-to excavate with conventional grading equipment. If blasting is required to make excavations, there could be noise as well as safety problems. . Policy 8-11: Blasting to facilitate excavations is discouraged and should be performed only after all other feasible techniques have been exhausted. ACTION PROGRAM: Geology, Soils, and Grading 8.2A Detailed geotechnical investigation.tion.For proposed development in the Western Dublin Planning Area, the City shall require a detailed geotechnical investigation which shall include the following:slope stability, seismic hazards,expansive soils,erosion control,fill settlement,and groundwater/springs. • Sloes stability_. As a part of detailed geotechnical investigation,major construction slopes should be evaluated and each landslide,debris flow area,rockfall area and area of soil creep that could potentially impact the proposed development should be evaluated by: 1) characterization of the extent of slope instability,2) assessment of the risk to the proposed improvements, and 3)preparation of appropriate mitigation measures to reduce the risk of damage to an acceptable level. • Seismic hazards. As part of the detailed geotechnical investigation,detailed analysis of seismic hazards shall be required for proposed projects in the Western Dublin Planning Area. Effects of ground shaking also shall be carefully evaluated in the geotechnical evaluation,including secondary effects such as rock falls and seismically-induced landslides. The potential hazards of liquefaction and lurching shall be assessed as well. • Expansive soils. As a part of detailed geotechnical investigation,the expansive potential of the various earth materials shall be evaluated and measures developed to reduce the risk of damage to improvements. • Erosion control. The City shall require erosion control plans. The erosion control plan shall include recommendations for preventing erosion and scour of existing drainage ways,consistent with biological and visual values.The plan shall include detailed measures for re-vegetation of exposed soil surfaces. • Fill settlement.As part of detailed geotechnical investigation,the City shall require detailed evaluation of potential fill settlement.This evaluation shall include measures to minimize risks due to fill settlement. All feasible measures should be taken to minimize the placement of structures,roads,and utilities over deep fill.Include special design considerations for deep fill. • Ground water and springs. Areas of possible shallow ground water shall be identified in a detailed geotechnical investigation. Recommendations to mitigate the adverse affects of shallow ground water in those areas as well as in areas of shallow ground water that may develop following grading shall be prepared,evaluated,and implemented. 8-7 A.\8914-SP.8914-SP8 Environmental Management 8.2B QM ing.Plan. A detailed grading plan shall be submitted to the City for review and approval. The grading plan shall be designed to meet City standards, reduce visual impact, and satisfy geotechnical requirements. The plan shall include: • An emphasis on the use of grading techniques which relate to natural land contours,with horizontal and vertical variation of slopes. Every effort shall be made to reduce earthmoving requirements and areas of land disturbance,while still meeting project objectives. Tops and ends of cut and fill slopes should be rounded,to provide a smooth transition to natural terrain. Small,naturally-contoured slopes should be used in preference to large,geometric shapes. • Demonstration that any landform alteration near streets maintains clear sight distances for traffic, bicycles,and pedestrians. • Demonstration that grading and other land alteration for geotechnical or hydrological reasons includes careful consideration of visual concerns. • Demonstration that grading near existing trees to remain includes special construction methods within the tree drip line, restrictions on grading and compaction near the base of trees, and other related requirements. • Identification of watersupply for grading and dust control.The use of recycled water for these purposes is highly preferred. 8.2C Excavation/blasting. The proposed grading plan shall be evaluated so blasting and the associated noise and safety concerns can be avoided if possible. If blasting cannot be avoided, a blasting plan shall be submitted to the City for approval. The blasting plan shall include provisions to control the impact of noise, as well as safety procedures to limit flying rock and ensure controlled detonation. Any blasting operation should be performed in accordance with Alameda County and City of Dublin regulations, and shall be <' approved by the City prior to implementation. 8.3 Biological Resources The Western Dublin Planning Area includes several distinct biomes, or assemblages of plant and animal species which normally exist together under natural climatic conditions.Biomes are often named for their dominant plant community, such as a riparian woodland biome. Figure 8-3 illustrates the biomes in the Planning Area. West Dublin Report 1 includes more detailed information about biological conditions, including lists of species recorddd for the Western Dublin Planning Area. 1 WPM Planning Team,Study RgaQrt 1 Environmental Settinolauni Considerations, Western Dublin,CA,1989. Available for review at the Planning Department,Dublin City Hall. 8-8 A.\8914SP\8914-SP8 Environmental Management Other Biological Implications of Environmental Alteration Wildlife Corridor Alteration Mammals and other wildlife species do not occupy a fixed place in the western Dublin area,but move in response to changing needs for food and water.Riparian growth along stream channels provides a preferred route for these movements. While some species have become adapted to human presence, other species prefer to stay clear of human habitation and activity. Existing wildlife corridors in Elderberry Canyon,Martin Canyon, and elsewhere would be disrupted by proposed development, and replacement would be necessary. Policy 8-18: Development in the Planning Area shall be designed to incorporate meaningful and functional wildlife corridors,so that both large and small wildlife species may move freely through the remaining natural areas.Existing corridors shall be preserved wherever possible; new corridors shall be designed for maximum long-term wildlife benefits. Proposed develop- ments should be designed to avoid creation of"habitat islands"which are cut off from adjacent tracts of natural habitat. Powerline Canyon Reservoir As noted in Chapter 5,a reservoir is proposed in Powerline Canyon as part of a water reclamation system.This reservoir would have fluctuating water levels at various times of the year.Located next to a large oak woodland, with no development in the immediate area, the reservoir has potential for serving as a feeding and watering site for birds. Other wildlife needs for access to the reservoir would have to be reconciled with security requirements, if since the reservoir is would be fenced to keep people out. Policy 8-19:Design and manage Powerline Canyon Reservoir for wildlife benefits consistent with the primary use of the reservoir, including provision of a year-around water supply. If Since fencing of the reservoir is required,provide a nearby ancillary water source for wildlife. Golf Course Wetlands New ponds and reconstruction of streams are proposed as part of the proposed golf course in western Dublin.With proper treatment,these features could provide wildlife benefits over time. Replacement of the current linear riparian corridor in Elderberry Canyon is particularly important. Policy 8-20:Include ponds and streams in the golf course design.Design these aquatic features for maximum wildlife benefits,with continuous wildlife corridors incorporated into the design. Provide a dense border of vegetation around these water features, consistent with golf course use. 8-11 A.g914-SF 8914-SP8 Environmental Management • Grassland revegetation. Remaining areas of grassland disturbed by development activity shall be reseeded, with an emphasis on re-establishing native grassland species. Grassland revegetation and management shall include consideration of interbiome dependency needs of certain species.Appropriate grassland buffers between woodland/scrub and developed areas shall be provided.The Environmental Management Plan shall indicate specific areas and standards for native grassland re-establishment. • Northern coastal scrub revegetation.Development plans shall have an emphasis on protection of this biome. Any areas of northern coastal scrub to be removed shall be replaced on a 3:1 basis. The Environmental Management Plan shall indicate precise areas and standards for revegetation. • Coast live oak woodland revegetation.The Environmental Management Plan shall include standards for protection of existing oak woodland to remain.Requirements for areas proposed for oak woodland revegetation shall be identified, together with the slope aspect and soil type. Removed trees shall be replaced at a minimum 3:1 ratio.Minimize night lighting in adjacent areas of woodland to remain. • Blackbird Pond enhancement.Detailed enhancement plans for Blackbird Pond shall be included with any development submittals affecting this area. Careful dredging is needed to remove sediments and XX restore the pond to its original size. Care must be taken to maintain or re-create an extensive shallow inshore ozone around the pond.Cattail control should be practiced in at least one-half of this zone area. It may be desirable to create an island in the pond for avian habitat.Primary use of this pond shall be for wildlife habitat,with no intensive use of the water for active recreation.Natural vegetation shall be planted in barren areas along the shore.Recreational uses such as picnicking shall be set back from the pond,with access limited to a dock and nature observation area.The water level shall be managed so that at least a minimum pool is retained throughout the year. Water depth near the shore should be established to minimize possible hazard due to unauthorized access by children. • Stock pond enhancement.A professional biologist shall evaluate existing stock ponds to see if they can serve as viable wildlife habitat areas. Enhance these ponds with revegetation where appropriate, or relocate ponds to settings near vegetative cover. • Golf course water features.Ponds and reconstructed stream channels on the golf course shall be designed to provide effective wildlife habitat while meeting recreation needs for the golf course.The golf course plans shall demonstrate how effective wildlife corridors can be created and connected to adjacent natural areas,with particular attention to the area near the clubhouse. • Powerline Canyon Reservoir. Provide a permanent water source for wildlife in this area, including a minimum reservoir pool with a non-fluctuating water level and/or a nearby water source.Wildlife use of the reservoir shall be consistent with water quality needs. • Grazing.If domestic livestock grazing is not to be prohibited entirely,the Environmental Management Plan shall identify non-grazing areas of the site. These shall include all stream channels and other sensitive areas. Fencing shall be provided to secure these areas from degradation by livestock. Other stringent standards shall be established to avoid continued overgrazing in western Dublin. • Riparian woodland. Modify development plans wherever possible to protect riparian woodland. Designate buffer zones along existing streams to remain;these buffer zones shall remain in open space. Coordinate any necessary stream channel alteration so that flood control and access needs are balanced by visual and biological concerns. Provide an adequate riparian corridor width to protect riparian vegetation and to downstream flooding. Revegetate stream banks with characteristic plan materials. Riparian woodland shall be replaced on a 3:1 basis. • Wildife corridors. Incorporate detailed planning for wildlife corridors into project site plans. 8-13 A:\8914 SP�S914-SP8 Environmental Management the potential for vandalism.An interpretive sign may be used at one location to describe the historic value of the walls and the need for their protection. 8AB The City shall encourage the following action: • InteMretive displays. Encourage the inclusion of interpretative displays in the Village Center or elsewhere to describe the history and prehistory of western Dublin.This display could include photos, taped interviews with area ranchers,and artifacts salvaggd during construction. 8.5 Noise and Electromagnetic Field Concerns Noise levels in the Planning Area were evaluated in a field survey. The detailed results of this investigation is described in Report 1 for western Dublin.3 In general,there are no major sources of noise within the Western Dublin Planning Area,except for occasional ranch vehicles. On the easterly slopes, highway traffic in the San Ramon Valley is audible. Construction noise from nearby developments is also present. The Schaefer Basin is exposed to noise from I-580. High-voltage transmission lines crossing the site generate noise,and also are of possible concern in terms of health effects from electromagnetic fields. ---------------------------------------------------------------------------------------------------------------- GOAL: To plan new development in western Dublin so that noise and electromagnetic field concerns are minimized. ---------------------------------------------------------------------------------------------------------------- Freeway Noise Although I-580 borders the Planning Area, a series of ridges serves as a barrier to noise transmission;the 60 and 65 decibel(Ld„)noise contours follow these ridgelines.Schaefer Basin is an important exception. In this area, the 60 dB contour extends as much as 1,800 feet from the highway centerline; residential development is proposed in this area. Policy 8-25: Development in the Schaefer Basin shall be designed to minimize the effects of noise. 3 WPM Planning Team, .Western Dublin Gene Plan Arnendment/Snecific Plan Study.Dublin, 1989,Chapter 5.9.Available for review at City of Dublin Planning Department. 8-16 A.\8914-SPS914-SP8 Environmental Management Construction Noise Development of the Planning Area will generate noise. Existing sensitive receptors include homes in Eden and Hollis Canyon, dwellings on the hills northwest and west of Eden Canyon, and homes in the Sunny Heights subdivision just west of the Planning Area. Policy 8-26: Projects in western Dublin shall include measures to minimize the effects of construction noise on residents of the surrounding area. Transmission Line Noise During humid weather conditions, the PG&E transmission lines generate high-frequency "crackling" noise from discharges in the air and on the tower hardware. These discharge phenomena are also the source of potential radio and television interferences. The PG&E transmission lines are a development constraint, not so much in terms of the noise reaching a high decibel level, but because of possible concern and irritation of future residents living near the lines.The greatest concern is for areas close to the towers. Policy 8-27: Development in western'Dublin shall be planned to maximize the distance from high-voltage transmission lines wherever possible. Transmission Lines: Potential Health Concerns In recent years, considerable attention has been focused on the possible health effects of electromagnetic fields generated by pe eAin high-voltage transmission lines and other sources.The powerlines crossing the Planning Area generate strong eleetrarnagnetie significant electric and magnetic fields. At this time,there is no conclusive evidence linking electromag- netic fields to health problems. Some studies have indicated ft eaffelatien, l'le ,.`he f eseff eh --etremagnetie fields d health an association of magnetic fields with certain types of cancer, but the scientific evidence is not conclusive. However,some government agencies such as the California State Department of Education have adopted guidelines for setback of schools and certain other activities which could be sensitive, as a prudent avoidance strategy. Policy 8-28: While research continues on the potential health effects of electromagnetic fields, the City of Dublin shall take reasonable precautions for future development near transmission lines in western Dublin. ACTION PROGRAM: Noise and Electromagnetic Field Concerns 8.5A The City of Dublin shall require the following as conditions of approval for applicable projects in the Planning Area. 8-17 A.-\89 t4-SP�S914-SPB Environmental Management • Freeway traffic noise.Development in the Schaefer Basin shall have site planning and building design standards applied to minimize noise impacts from I-580,in compliance with the City's adopted Noise Element.In particular,berms or equivalent measures shall be used along the south edge of residential areas within sight of the freeway. • Co struction noise.Apply detailed noise control standards for projects in western Dublin.Require the use of berms and natural landforms wherever possible to reduce the duration and intensity of noise. • Transmission line noise. Site plans for development in western Dublin shall be modified to shift development away from transmission lines and towers wherever possible. Future residents near the transmission lines shall be provided a disclosure statement before purchasing or renting homes,noting that the transmission lines will be generating noise in humid conditions. The following areas are considered sensitive to transmission line noise. Within 250 feet of towers for building pad elevations below 850 feet. Within 200 feet of towers for building pad elevations between 850 and 900 feet. Within 100 feet of any tower for building pad elevations above 900 feet. Within 50 feet of the right-of-way for the entire line. • Transmission ices• health concerns.Potential homeowners and renters near the tfamfflissien lines S in areas sensitive to transmission line noise also shall be given a disclosure statement, noting that research is continuing on the potential health effects of electromagnetic fields. • Noise standards. Apply the traffic noise requirements of the Dublin General Plan to new development in western Dublin. Review all development proposals in noise-impacted areas on the project site, for compliance with applicable City standards. 8.6 Visual Resources Rugged ridges and canyons with woodland,open grassland, and picturesque rock outcroppings in the Western Dublin Planning Area combine to create a landscape of exceptional scenic value. The Planning Area is part of an open space corridor which provides strong visual definition for urban landscapes to the east and west. Prominent ridges and landmarks on the site can be seen from San Francisco to the Altamont Pass.The Planning Area also has special visual significance to travelers on Interstate 580, which borders the site on the south. Alteration of the site thus could potentially affect the visual image of this part of the Bay Area for a large number of area residents and highway travelers. A detailed analysis of visual resources is included in West Dublin Report 1 4. This report notes that, in comparison to nearby urban landscapes, the western Dublin area has been relatively 4 WPM Planning Team, i g Considerations, Western ,1989,Chapter 5.8. Available for review at the Planning 8-18 A.\9914-SP8914-SP8 Environmental Management Home Occupations and Neighborhood Work Centers The concept of the"electronic cottage",enabling people to work at home some or all of the time, has been receiving increasing attention as a method of reducing traffic congestion and resultant air pollution.In addition to telecommunication-related work activities,other home occupations have a long tradition, and are a desirable approach, although their widespread use is somewhat limited by psychological disadvantages of working at.home. Home occupations need to be limited to "inconspicuous uses" which do not disturb nearby residents. An experimental concept now being tried in various locations is the neighborhood work center. With this approach,a company or government agency sets up a satellite office near a residential area.Workers in the vicinity can then walk or drive a short distance to the work center, and still benefit from being in a work environment away from their home. A variant on this idea is the shared office facility,where private office space for self-employed individuals is combined with common access to equipment and personnel. Neighborhood work centers and shared office facilities would be appropriate in the Village Center and the Neighborhood Center. Policy 8-38: Permit home occupations,neighborhood work centers,and shared office facilities in western Dublin, with suitable controls to avoid neighborhood disruption. Other Air Quality Issues Fireplaces and Wood Stoves While fireplaces and wood stoves are an attractive feature in homes,their collective use can add to air quality problems.Improved models of efficient wood stoves are available which greatly reduce pollutants.The U.S.Environmental Protection Agency(EPA)has approved certain units for use. Policy 8-39: Require the use of EPA-approved wood stoves and fireplaces if these features are planned for new housing in western Dublin. Construction Dust Large-scale grading would be required for development in western Dublin. Without proper controls,construction dust can become a health concern as well as a nuisance for area residents. Policy 8-40: Require effective dust control measures for grading activities in western Dublin. Emphasize the use of recycled water for dust control. Educational Program: Pamphlet for New Residents As new.residents in western Dublin move in,they are in a position to take advantage of the air quality conservation opportunities provided in their community. Information should be made available for this purpose. 8-24 A\8914-SPM 14-SP8 Environmental Management Policy 8-41: Provide information for western Dublin residents about opportunities for reducing air pollution. ACTION PROGRAM: Air Quality 83A Perinitprocess�n_g priority.The City shall actively encourage specified types of development which can help to reduce vehicle emissions,in keeping with the standards of this Specific Plan.City staff shall be directed to give priority for permit processing of uses which are encouraged in the Specific Plan. 8.713 Zoning and other land use regulation in western Dublin (1) Permit home occupations which do not require significant signage,visitors, truck deliveries,noise, or other significant neighborhood disturbance.Stipulate home occupations as a permitted use for all residential areas in western Dublin. (2) Permit neighborhood work centers (satellite offices) in the Village Center and in the Neighborhood Center.Include satellite and other offices as permitted uses in these locations. (3) Permit the location of at least one full-service gas station in western Dublin,which would provide on-site tow truck service.Include full-service gas stations with tow truck service as a permitted use in the freeway commercial distri ct,subject to design review. 8.7C Building permit processing (1) Where consistent with State law,include standards for efficient EPA-approved wood stoves and fireplace units as a supplement to the Building Code for western Dublin. Require identification of equipment on building plans,with data about efficiency. (2) Where consistent with State law, require electric outlets in all garages of residential units in western Dublin,conveniently located and suitable for recharging of electric cars. 8.7D Public works standards.In conjunction with adoption of street standards for western Dublin,include a statement that golf carts may be used on dedicated pathways, consistent with applicable regulations. Consider a golf cart path along Hollis Canyon Boulevard to allow golf cart access from homes in the Golf Course Neighborhood to the Village Center. 8.7E Grading _permit processing. Require strict dust control measures for grading in western Dublin, in keeping with City standards and practices. 8.7F Other conditions of approval (1) Require a transportation management plan in conjunction with project approval for the Eden Canyon Country Club project and the Cronin Ranch project.Encourage this planning to be completed as a coordinated effort. The transportation management plan shall include detailed measures to reduce traffic, such as arrangements for van pooling,off-peak commuting for golf course employees,and other measures. (2) The required pamphlet for new residents(see Action Program 8.1 C)should include specific information on how they can help to minimize air pollution,including use of local trails,bicycle routes,transportation management,and other measures noted in this section. LL 8-25 A.\8914-SP\8914-SP8 Design Policy 9-5: Use innovative site planning and design techniques to preserve privacy while promoting social opportunities in residential neighborhoods.In particular, locate windows of homes so that there is minimal visual intrusion on neighbors' windows and backyards. Garages and Driveways Two parallel trends have combined to cause a site planning concern over the nature of garages and driveways in residential development. First, garages have been getting larger; two-car garages have become a minimum standard for single-family residential development. Concur- rently, lots have been shrinking in size. The result often is a streetscape dominated by large garages and driveways. The street then takes on the role of a service corridor rather than a multi-use ceremonial entry and social space. Policy 9-6: Garage and driveway placement and size shall be carefully evaluated in order to minimize a garage-dominated streetscape. Use alleys, auto courts, setbacks and other site planning techniques in order to improve visual quality of residential neighborhoods,particular- ly in small-lot subdivisions. Security How people feel about their neighbors, and how they believe their neighborhood reflects their values, will influence the degree to which they will actively participate in protecting that neighborhood. Site design is one of many factors that can contribute to safety and security. Policy9-7: Site planning should provide for police and security guard surveillance in all public areas. Informal surveillance by residents should be encouraged. Entrances to the project and to individual housing clusters should be structured and clearly marked. Lighting shall be provided in areas of night use, such as access walks to the Village Center. ACTION PROGRAM: Site Planning 9.2A Privacy plan.Development applications for each residential district shall include a privacy plan,with diagrams,elevations,and/or standards to assure that each residential unit will have satisfactory privacy. 9.2B Lot orientation for energy conservation.As part of tentative map review for residential projects within the Planning Area, lot orientation for energy conservation shall be evaluated by the City. As a desirable goal, a minimum of 65%of lots shall have their major axis within 30 degre es east or west of a north-south. alignment.However,in hilly terrain,proper lot orientation needs to be balanced against other site planning constraints.Exceptions to this stmdard shall be considered when it is demonstrated that there would be no significant adverse effects on energy use due to lot orientation, or when innovative energy conservation techniques(beyond State standards)are applied to achieve equivalent energy benefits. 9.2C Garages and driveways. As part of detailed review of the project by the City,garage placement shall be evaluated.For detached single-family homes,street-facing garages generally shall not extend beyond the front facade of the home. Exceptions may be allowed in the cases of homes on steeply-sloping lots, and custom homes on lots of more than 8000 square feet.In place of garages which dominate the street frontage, 9-3 A.\8914-SP8914-SP9 Design Coordinated Building Treatment It is desirable to achieve a sense of identity within housing clusters. This is necessary for practical reasons(ease of identifying and describing where one lives,and for proprietary reasons) to add a level of pride to owning a home within a distinctive neighborhood. Policy 9-10: Compatibility within building groups should be achieved. Dwelling units or other structures should offer variety in size and layout,but should relate to one another by harmonious use of materials, colors, roof styles,and details within each cluster. Supplementary colors and trim details should provide interest and refinement without undue contrast with the basic theme. Building Materials The East Bay residential heritage reflects a variety of styles. The particular design style for buildings in western Dublin is not as important, however, as careful selection and use of appropriate building materials. Policy 9-11:Building materials should be selected that are durable and visually appealing. Building Setbacks Traditional application of uniform building setbacks has sometimes resulted in monotony in residential neighborhoods. Flexible setbacks,particularly in western Dublin's hillside terrain, can provide a more satisfying built environment. Policy 9-12: Variable setbacks should be used to allow a variety of lot sizes and housing arrangements in western Dublin. ACTION PROGRAM: General Building Design Policies 93A Zoning Regulations.The City shall establish detailed zoning regulations specifically geared forwestem Dublin,based on current City standards where appropriate,but allowing flexibility for special conditions in western Dublin.These zoning regulations shall include limitations on height,as well as setbacks. 9.3B Design Review Committees, Deai-,n b Gity e design pfineiples:All construction shall be subject to the City's site development review guidelines,permits and any supplemental design conditions. 9-5 A X8914-SP8914-SP9 Design Policy 9-14:Provide convenient parking which does not detract from the pedestrian emphasis of the Village Center.Instead of one large lot,provide grouped parking primarily at the side or rear of buildings. Allow limited on-street parking where appropriate. Make parking clearly available to shoppers, through the use of signage and visibility of parking lots.Locate parking, deliveries, trash pickup, and other similar services at the side or rear of buildings. Pedestrian Scale - The detailed design of the Village Center can be an important factor in encouraging people to walk rather than drive.Pedestrian amenities along the approaches to the Center,as well as within the Center itself, can make walking an enjoyable experience. Policy 9-I5: Include pedestrian amenities such as trees and shade structures, benches, sculpture,and pedestrian-scale lighting along the approaches to the Village Center. Within the pedestrian-oriented areas of the Village Center, establish controls on the height and length of building walls, the amount of uninterrupted asphalt paving, street width, distance between crosswalks,and the continuity of shop fronts.Building facades and entries should be varied and articulated to provide visual interest to pedestrians. Provide features such as porches, bays, balconies,arcades,and street level windows.Encourage pedestrian-oriented activities such as outdoor cafes and shops with attractive window displays. <:> ACTION PROGRAM: Village Center 9AA Use Permit Requirements. A conditional use permit shall be required for the Village Center,at the time that this part of the project is developed. The conditional use permit shall serve as the basic development plan approval for the Village Center. As part of the submittals for this permit the following design-level information shall be provided. • Site plan,with designation of high-activity areas and pedestrian corridors. Pedestrian pathways from nearby residential areas shall be included. Master landscape plan, with attention to providing shade for pedestrian pathways and parking lots, energy-conserving features, solar access, and water-conserving features, including DSRSD's Best Management Practices. • Desists standards to assure that the project is designed at a pedestrian scale(see Action Program 9.4B). • Signage ,with an emphasis on clear orientation. • Lighting.plan.There shall be anemphasis onpedestrian-scaled light fixtures.Wall-hung exterior lighting shall be a preferred approach along pedestrian passageways, at comers of buildings, and on building walls next to parking lots. Bollard lights at approximately 42 inch mounting height, and post lights at 12 to 18 foot mounting height may also be used. Harsh colors shall be avoided for general lighting. The lighting plan shall be designed to minimize light and glare impacts for residents of the Village Center area. Lighting of signs shall be strictly controlled. Service provisions,including screened trash areas and mechanical equipment. 9-7 AM914-SA8914-SP9 Design Common Open Space and Outdoor Living Space Since individual outdoor living areas are limited for multi-family units,access to common open space is essential.Central recreational facilities help to create a high-quality living environment. Policy 9-18: Provide common open space in multi family residential developments, with convenient access from all units.Each multi family residential district shall include significant private common open space, including children's play'areas, unless the district is designated for senior housing. Individual outdoor living space, even if limited to a balcony or small patio, adds to the quality of an apartment or townhouse unit. Policy 9-19: Provide private outdoor living areas for residential units in western Dublin; designated affordable housing units may be excluded from this requirement. Outdoor Storage and Mechanical Equipment Utility companies (electricity, gas, telephone and cable TV)need to have ready access to their lines and equipments. However, above-grade transformers,valves,meters, and relay boxes are often placed in conspicuous locations, detracting from otherwise pleasant views. Policy 9-20: Outdoor storage areas and mechanical equipment shall be enclosed or hidden from view. Mechanical equipment shall be placed out of view. ACTION PROGRAM: Multi-Family Residential Design 9.6A The City of Dublin shall require the following as conditions of project approval: • Designation of a common open space area with recreation facilities. • Common open space shall be landscaped,and maintained through a homeowners association. • Outdoor living areas.The City's zoning standards for multifamily residential development in western Dublin shall specify that ground level patios or terraces shall be single- or multi-level and contain a minimum flat area of 200 square feet. Upper story decks shall be a minimum area of 70 square feet. Exceptions may be made for designated affordable housing units. • Outdoor storage. Garden sheds,pool equipment enclosures,and trash storage areas shall be placed in unobtrusive locations.Trash receptacles shall be placed in walled enclosures. • Mechanical equipment. Above-grade transformers, irrigation valves and controllers, gas and electric meters and valves should be accessible,but should not be placed in the immediate foreground of any site or building.Provide backflow preventers in accordance with applicable regulations. 9-10 A:\8914-SP8914-SP9 Design ACTION PROGRAM: Landscape Treatment 93A vM ter Landscape Plan.As a condition of development approval for each project in the Specific Plan area,a master landscape plan shall be prepared for the project.This plan shall include the following: • Special provisions for visually-sensitive areas, particularly visible slopes and ridgelines. Disturbed slopes shall be planted with native trees and compatible vegetation,in a pattern similar to existing site conditions. Careful landscape treatment shall be used-to minimize abrupt contrast between irrigated areas and natural open space. J • Planting at the interface of development and natural open space shall be designed for a smooth visual transition. Ground cover,shrubs and trees shall have irregular shapes rather than geometric patterns or straight edges. See Figure 9-5 (Perimeter Slope Treatment). • The landscape plan shall be coordinated with fire protection planning.Planting shall be used as needed to reduce visual impact of firebreaks and should incorporate fire retardant plant material near or adjacent to homes. • The landscape plan shall include plantings to soften the visual effect of sound walls, and shall have strategically-located trees and shrubs to reduce glare impacts where needed. • Plantings and irrigation systems shall be designed to provide maximum water conservation benefits. Emphasis shall be placed on use of drought-tolerant native plants,with little orno irrigation requirements once established. Aggressive non-native species capable of crowding out native vegetation shall be avoided.Apply water conservation measures in conjunction with DSRSD's BestManagement Practices. • Energy conservation features,with use of plantings and structures to control heat gain. • Safety considerations shall be emphasized,including selection and placement of plants to allow clear vision at intersections. • A Landscape Management Program is needed to guarantee establishment and continued care of plantings, including replacement of plants as needed, reseeding of eroded or disturbed slopes, and general maintenance of landscaping in open space areas. 9.7B Master Lighting Plan.Asa condition of approval for each project in the Planning Area,amaster lighting plan shall be submitted to the City for review and approval. 93C Master Fencing Plan.As a condition of approval for each project in the Planning Area,a master fencing plan shall be submitted to the City for review and approval. 9.7D Master Si onager Plan.Asa condition of approval for each project in the Planning Area,a master signage plan shall be submitted to the City for review and approval. 9.8 Golf Course and Clubhouse Golf course ownership,management,and access issues are discussed in Chapter 7. This section focuses on design aspects of the golf course. 9-14 A.\8914-SP,8914-SP9 Financing development within that Specific Plan area,except where specific existing City,County or State sources are available. Policy 10-2: Allocate the backbone infrastructure costs to property within the Specific Plan area based on the general principles of benefit received, with consideration of the financial feasibility of the proposed land use. 'Backbone infrastructure" means public infrastructure outside of building tracts. Policy 16-3: Adopt an Area of Benefit Ordinance and form an Area of Benefit for the Specific Plan area that establishes a fair share cost allocationfor public improvements required to serve development of the Specific Plan area. Policy 10-4: Use pay-as-you-go financing to the extent possible. Use debt financing only when essential to provide facilities necessary to permit development or to maintain service standards. Policy 10-5: Require development projects in the Specific Plan area to ficnd the oversizing of facilities if required by the City,subject to reimbursement from fiiture developments benefiting from the oversizing. Policy 10-6: Require developers who proceed ahead of the infrastructure sequencing plan to pay the costs of extending the backbone infrastructure to their project subject to fitture reimbursement. Policy 10-7: Require dedication of land for road improvements,park and other publicfacilities, and construction of such improvements consistent with City-wide policies. Policy 10-8: Provide for reimbursements from any other benefiting areas for costs that Specific Plan area owners are required to produce. Policy 10-9: Issue bonds(such as Mello-Roos andlor Assessment District bonds) only so long as the security for those bonds equals 300 percent (or more) of the bond value. Developers shall be required to finance privately any infrastructure costs that would cause bond issues to fail to meet the above-stated criteria. Policy 10-10:Issue bonds(such as Mello-Roos and or Assessment District bonds), only so long as the annual special assessment or special tax and 1.0 percent regular property tax and existing bonded indebtedness does not exceed 2.0 percent of property value.Consider exceptions to this policy per approval by the City Council. 10-9 A:\8914-S P\891 ASS P 10 Financing Table 10-5 makes clear that this project should probably attempt to issue bonds for only about 50 percent of the infrastructure eligible for financing; the developers should be required to privately finance the remainder. Table 10-6 more clearly allocates the bond financing costs among different types of housing. Once again, this table indicates that annual special assessments would equal up to 2.0 percent of property value; when added to the 1.0 percent regular property tax, and other current assessments,the total taxation level would be considered too high. 10.6 Action Program »< ACTION PROGRAM: Financing >< 10.6A The City of Dublin should take the following actions to carry out the financing policies of the Specific Plan. • Developmt A=ement. For each project in the Planning Area, prepare and adopt a developmen en t agreement that spells out the precise financial responsibilities of the developer. • Area of Benefit Ordinance. Adopt an Area of Benefit Ordinance and form an Area of Benefit for those properties benefiting from construction of public improvements described in the Specific Plan. • ,Analysis of Financing Techn;oues.Analyze various alternatives for public financing techniques further in order to identify and develop the most flexible and lowest cost financing program for necessary public infrastructure and facilities in the project area.Each technique or combination of techniques should be evaluated for its suitability for funding public infrastructure and facilities costs and its capacity to insure both adequate and timely provision of infrastructure and facilities,and lowest possible burden to new residents.In addition,the financing program should be consistent with financing policies set out above. Public financing mechanisms that the City should consider as part of this analysis may include: S„ .al Assessment District or Mello-Roos CFD. Analyze use of Mello-Roos CFD, Special Assessment District or an appropriate combination of these public financing mechanisms and/or other appropriate public financing mechanisms to finance construction of the infrastructure (outlined in Tables 10-1 and 10-4) to serve the Areas of Benefit. Some of the special taxes or special assessments may be due upon application for building permits,and the remainder may be financed with the appropriate bond mechanisms. L andscaning and Lighting District.Analyze use of a district to fund certain ongoing costs such as mini-park maintenance and fire prevention and suppression in the open space areas surrounding western Dublin. • S,eolo .ic Haz T& Abatement District. Aftlyze use of Establish a GRAD or equivalent entity to periodically inspect and maintain unstable slopes in the western Dublin area. Assess a special fee on property owners in the area to pay for inspections and maintenance as well as create a reserve fund from which to make any necessary repairs. 10-12 A:\8914-SP8914SP10 11. IMPLEMENTATION AND ADMINISTRATION The preceding chapters of this Specific Plan provide the plans,policies and guidelines for the orderly development of the Western Dublin Planning Area. This chapter sets forth a variety of implementing steps and regulatory and organizational proceedings to implement the Specific Plan. 11.1 Summary: Specific Plan Implementation Program The following shows the approximate sequence of the key implementing steps that should be followed to effectively implement this Specific Plan. • Certify the Program Environmental Impact Report- City • Adopt CEQA Findings - City • Amend the General Plan as required- City • Adopt the Specific Plan- City • Adopt prezoning - City • Amend the City's and DSRSD's Sphere of Influence boundary to include all of the Western Dublin Specific Planning Area-LAFCO • Process annexation request and complete annexation to the City and DSRSD-LAFCO/ftttd City/DSRSD • Detach the Planning Area from the Hayward Area Recreation and Park District - LAFCO/HARD • Cancel Williamson Act contracts -City • Conclude property tax exchange agreement with County • Adopt design review procedures • Approve Master Parcel Maps(if needed),Master Grading,Utility and Drainage Plans-City 11-1 AA8914-S"914SP1 I Implementation and Administration • Accept land dedications for public facilities -DSRSD/other agencies • Adopt Environmental Management Plan- City • Adopt District Planned Development Plans- City • Approve Tentative and Final Subdivision Maps- City • Adopt Public Improvements Plans - City • Adopt Financing Plans - City • Other Actions: development agreements,district formation, etc. -various entities • Administer Specific Plan - City • Maintenance and Operation Program- City 11.2 Key Implementing Actions of the Specific Plan EIR Certification To meet the requirements of the California Environmental Quality Act (CEQA), a program Environmental Impact Report (EIR), as authorized by Section 15168 of the CEQA guidelines, has been prepared to assess the environmental impacts of the Western Dublin Specific Plan. The Specific Plan's EIR has been prepared as a program EIR to cover the development of the Western Dublin Planning Area as a total undertaking,although development is expected to occur in several increments over a number of years by several developers. The Specific Plan's Final EIR must be certified by the City as accurate and complete,once all comments on the Draft EIR have been responded to. The City's action to certify the Final EIR does not constitute approval of the Specific Plan. Rather, it indicates that all required environmental information has been presented to the City's decision-makers and the public. CEQA Findings The City must approve Findings of Fact and Statement of Overriding Considerations,as required by Section 15091 of the CEQA guidelines. Such findings explain how the City has dealt with each significant adverse environmental impact and the project alternatives offered in the Final EIR. These findings must be approved prior to the first discretionary action on the proposed project. 11-2 A:\8914-SP8914SP11 Implementation and Administration Responsibilities for Key Implementing Actions The following table indicates the responsibilities for preparation of the documents discussed above: Table 11-1: Responsibilities for Key'Implementing Actions Responsibility for Document Key Implementing Actions Pre arp ation Adoption by EIR Certification City City CEQA Findings City City General Plan Amendments City City Specific Plan Adoption -- City Prezoning City City Sphere of Influence Boundary Adjustments City/DSRSD LAFCO Annexations City/DSRSD LAFCO/City Detachment from HARD HARD/City LAFCO/HARD Cancellation of Williamson Act Contracts City City Design Review Procedures City City Master Parcel Map (Optional) Developers City Master Grading, Utility and Drainage Plans Developers City District PUD Plans Developers City Tentative Map Developers City Site Development Review -- City Public Improvement Plans Developers City Final Subdivision Map Developers City Park Improvement Plans City City Financing Plans Developers City 11-7 AA8914-SP8914SP11 Implementation and Administration • Provide the terms for reimbursement when a developer advances funding for specific facilities which have community-wide or area benefit. • Provide mutual certainty to both the City and the developer regarding entitlements to the developer in return for commitments for public improvements. The City should first develop a Master Development Agreement to serve as the format for all development agreements within the Western Dublin Planning Area. The conditions included in this Master Development Agreement will then be tailored to the special condition for each major project area and the development projects within it. The City should also adopt necessary enabling legislation, if needed, to authorize the use of development agreements. Area of Benefit Ordinance The City shall adopt an Area of Benefit Ordinance and form an Area of Benefit for those properties benefiting from construction of public improvements described in the Specific Plan. Area of Benefit fees may be enacted by the City of Dublin through adoption of an ordinance, without voter approval.The fee must be directly related to the benefit received.It does not create a lien against property,but must be paid in full as a condition of approval.Benefitting properties may be given the option to finance the fees by entering into an assessment district(1913 - 1911 Act) or Mello-Roos CFD. Analysis of Financing Techniques Analyze various alternatives for public financing techniques further in order to identify and develop the most flexible and lowest cost financing program for necessary public infrastructure and facilities in the project area. Each technique or combination of techniques should be evaluated for its suitability for funding public infrastructure and facilities costs and its capacity to insure both adequate and timely provision of infrastructure and facilities,and lowest possible burden to new residents.In addition,the financing program developed should be consistent with financing policies set out in the Specific Plan.Public financing mechanisms that the City should consider as part of this analysis may include: • Special Assessment District or Mello-Roos CFD. The City shall analyze the use of a Mello-Roos CFD,Special Assessment District,or a combination of these and other financing mechanisms to finance construction of the required public(outlined in Tables 10-1 and 10-4 in Chapter 10)to serve the Area of Benefit. Some of the special taxes or special assessments. may be due upon application for building permits, and the remainder may be financed with the appropriate bond mechanisms. • Landscaping apin nd ightl_n istrict.The City shall analyze the use of a district to fund certain ongoing costs such as maintenance of street lights and landscaping.

This section discusses the sequence of major public infrastructure phasing, including grading, construction of streets and utilities, and other public improvements. A new fire station and other key facilities must be installed before any homes can be occupied in the western section of the Planning Area. Eden Canyon Country Club Phasing Public Infrastructure Phasing of public infrastructure costs is based on the project proponent's infrastructure phasing plan ,which shows that most infrastructure costs would occur from 1993 to 1998. This analysis assumes aphasing approach where nearly all the infrastructure would be completed before construction of private homes. 11-14 A.\8914-SPW 14SP I 1 RESOLUTION NO. 92-023 A RESOLUTION OF THE PLANNING COMMISSION OF THE CITY OF DUBLIN A RESOLUTION RECOMMENDING CITY COUNCIL CERTIFICATION OF THE FINAL ENVIRONMENTAL IMPACT REPORT FOR THE WESTERN DUBLIN- GENERAL PLAN AMENDMENT AND SPECIFIC PLAN Recitals 1. In response to residential development applications from Eden Development Group and Schaefer Heights, .Inc. , and later, the Milestone Land Development Corporation, the City of Dublin undertook the Western Dublin Study to plan for the future development of the Western Dublin Expanded Planning Area. 2 . The City Council and Planning Commission conducted three joint public study sessions relating to planning issues in western Dublin. The December 13 , 1989 study session identified existing site conditions in the study area and described the site's development constraints and opportunities. The February 28, 1991 study session considered different land use options for the study area and chose the applicants' proposals as the preferred alternative for further study. The November 11, 1991 study session addressed visual and parkland issues in the study area. 3 . With the identification of a preferred alternative on February 28, 1991, the City prepared a Draft General Plan Amendment and a Draft Specific Plan, to allow the future development of a residential community of approximately 3260 units on approximately 3255 acres of land. 4 . The project included planning for the future development of a residential community of single-family and multiple family residences with supporting community and commercial facilities, together with an 18-hole championship golf course and other park and open space facilities. 5. The City completed an Initial Study on the project and determined that an Environmental Impact Report (EIR) was required. A Notice of Preparation dated September 8, 1-989 was prepared, published in a newspaper of general circulation and mailed to Responsible Agencies and various other interested parties. 6. A Draft Environmental Impact Report was prepared on the project, including the General Plan Amendment, Specific Plan, Prezoning, Annexation to the City and other jurisdictional boundary changes. The Draft Environmental Impact Report consisted of a Draft Environmental Impact Report - Part One of Two Documents, and Appendices for the Draft Environmental Impact Report- Part Two of Two Documents, both Parts dated December, 1991. A Notice of Completion was filed with the State Secretary ATTACHMENT 41 of Resources via the State Clearinghouse on January 13, 1992 (SCH No. 89091211) . 7 . The Draft Environmental Impact Report was circulated for a 45-day public/agency review period beginning on January 17, 1992 and ending on March 2, 1992. Public notice of the availability of the Draft Environmental Impact Report was published in a newspaper of general circulation. 8 . The City of Dublin Planning Commission held a duly noticed public hearing on the Draft Environmental Impact Report on January 29, 1992, which hearing was continued to February 18, 1992, and March 2, 1992 . At these hearings, and through submitted written comments, the Planning Commission received comments on the Draft EIR from the public, responsible agencies, other governmental and private organizations as well as from City staff and its consultants and the project sponsors and their consultants. 9. The City prepared responses to comments on environmental issues received during the public review period and at the public hearings, which responses clarify and amplify the information contained in the Draft EIR, providing good faith reasoned analysis supported by factual information. The comments and responses to comments were published in four parts, on March 23 , 1992, March 24 , 1992 , March 26, 1992 and March 30, 1992 , and were distributed to or otherwise made available to the Planning Commission, Responsible Agencies and other interested parties. 10.
