Gillarde, Project Consultant ATTACHMENTS: 1. City of Dublin General Plan Technical Revisions, dated August 13, 1992 2. Resolution Recommending City Council Adoption of Technical Revisions General Plan Amendment 3. Negative Declaration, dated February 25, 1991 4. General Plan Technical Appendices, dated February 1984 RECOMMENDATION: ic 2. 1. Open public hearing and hear staff presentation Take public testimony 3. Ask questions of Staff and the public 4. Close public hearing 5. Discuss general plan amendment 6. Approve the resolution FINANCIAL STATEMENT: Cost to prepare amendment (graphics and printing) estimated at $2,320. Funds are available in the FY 92-93 budget. BACKGROUND: A recent review of the City's current general plan (adopted February 1985) has revealed that certain information should be added in conformance with Government Code provisions for general plans. The City used the 1990 General Plan Guidelines published by the California State Office of Planning and Research for guidance in this general plan revision effort. Most of the changes involve adding statutory references, cross referencing statutes, or updating text to reflect statutory changes. Some implementing policies have been added to strengthen existing City programs. In addition, policies adopted by previous City general plan amendments have been included with this general plan amendment and physically inserted into the general plan document. The above changes have been made to the plan and are now proposed for incorporation into the document (Attachment 1). This would be accomplished by the adoption of a resolution amending the existing city general plan (Attachment 2). A negative declaration was prepared for this project and was circulated to the appropriate agencies (Attachment 3). ITEM NO. go2.. COPIES TO: Project Planner Agenda File Application File DISCUSSION: A. Technical Revisions to the Plan As discussed above, language has been added to the Dublin General Plan that generally explains or clarifies certain sections of the plan. In some instances, information has been added that was previously lacking for specific areas, such as intensity standards for each commercial land use category. The additions are to bring the plan into better conformance with the 1990 State General Plan Guidelines. The changes do not affect the policy direction of the plan and it remains as adopted in 1985. The most important technical revisions to the plan are outlined below by general plan chapter. Attachment 1 contains the actual text changes, indicated by underlining and s4iikeeih Chapter 1.0 Background Several paragraphs have been added to the introduction to clarify the format of the current general plan and where certain information can be located. Reference is made to current planning studies underway in western and eastern Dublin. Note has been made that the Western Dublin General Plan Amendment and Specific Plan was recently approved by the City. Pages 1-6 through 1-7 contain additional intensity standards for commercial development, as required by the Government Code and discussed in the State General Plan Guidelines. Chapter 2.0 Land Use and Circulation Section: Land Use Element Paragraphs have been added to the introduction clarifying the required scope and content of a general plan land use element. The location of certain required information such as density and intensity standards, distribution of land uses and open space is also provided in these introductory paragraphs. Table 2.2 has been updated to reflect current potential housing sites. Explanatory language was added to pages 2-4 and 2-5 about the Downtown Specific Plan which was adopted in 1987. Chanter 3.0 Land Use and Circulation Section: Parks and Open Space Explanatory language was added to the introduction describing the required contents of an open space element. On page 3-2, language was added describing the City's current park facilities and additional implementation policies added to page 3-3 that would further promote acquisition of needed outdoor recreation sites. Chapter 4.0 Land Use and Circulation Section: Schools. Public Lands and Utilities Element Explanatory language was added to the introduction specifying the required contents of this portion of the land use element. Additional implementing policies were inserted on page 4-1 to ensure provision of adequate school facilities in the Extended Planning Area. The discussion of solid waste was updated to reflect current legislation for source reduction and recycling. Accordingly, implementation policies were added to ensure 2 current city programs are enforced. An implementation policy was also added to the sewer treatment section (page 4-4) to ensure the availability of adequate treatment prior to construction. Chapter 5,.0 Land Use and Circulation Section: Circulation and Scenic Highways Element This chapter contains the most extensive technical revisions. In addition to language added to the introduction describing the required contents of a circulation element, a complete set of street standards has been added (see pages 5-2 through 5-7). On page 5-11, a brief description of funding for road improvements has been inserted. While these revisions are fairly extensive, they do not alter the current policy direction of the general plan. The standards were included for the purpose of better defining the City's current and future roadway system. Chapter 6.0 Housing Section This section has been deleted from the document since it was recently updated in 1990. A reference is provided indicating where the revised housing element can be obtained. Chapter 7.0 Environmental Resources Management Section; Conservation Element The major changes to this element are the addition of explanatory language to the introduction (page 7-1); similar language added to the section addressing stream corridors (page 7-2); and expansion of the open space section to include language and measures that further strengthen open space acquisition and maintenance (pages 7-5, 7-6). Chapter 8.0 Environmental Resources Management Section: Seismic Safety and Safety Element Explanatory language has been added to the introduction (page 8-1); clarifying language about fire service (page 8-4); further explanation about flooding (pages 8-5, 8-6); and an implementation policy about hazardous waste (page 8-7). Chapter 9.0 Environmental Resources Management Section: Noise Element Language was added to the introduction specifying the required contents of a noise element (page 9-1). Discussion was added about future noise sources created by the proposed BART stations (page 9-1). The BART EIR was referenced for further infor m ation. B. Incorporation of the Technical Appendices, Although the Technical Appendices are contained in a separate document (Attachment 4), they contain information relevant to the general plan elements and should be adopted as part of the plan. A section has been included in the attached resolution that would formally adopt the Technical Appendices as part of the general plan. 3 C. Incorporation of Previously Adopted Policies Prior to this proposed general plan amendment, there were several previous general plan amendments which added certain policies to the City's general plan. These policies were never physically inserted into the plan document. This current general plan amendment provides the opportunity to do this and so they have been included in the August 1992 amended document. They are located on the following pages: Addition of the Low -Density Single Family land use category, page 1-6 Guiding Policy G, page 5-8 Guiding Policy A, page 7-5 Implementing Policies B through G, pages 7-5 and 7-6 Implementing Policy B, page 8-5 A section has been included in the resolution that would physically incorporate these statements and policies into the City's general plan document. RECOMMENDATION: Staff recommends that the Planning Commission adopt the resolution recommending City Council adoption of the technical revisions general plan amendment.

Policies for the Extended Planning Area are being formulated through general plan amendment and specific plan studies currently underway for the Western and Eastern Extended Planning Areas. These documents are expected to be comkleted in 1992. As of July 1992, a General Plan Amendment and Specific Plan were adopted for the Western Extended Planning Area and are available from the City Planning Department. The text and plan maps adopted by the City Council in Volume -I: --Plan Polieies-of-the-General-Plan-eonstitutes this General Plan constitute a guide for the day to day physical development decisions that shape the social, economic, and environmental character of the city and its extended planning area. State Law requires Dublin to adopt a General Plan within 30 months from the time it commenced operation as a city on February 1, 1982. The law (Government Code 65300) directs each jurisdiction to include "any land outside its boundaries which in the planning agency's judgment bears relation to its planning." Consequently, the Dublin Planning Area, including the Extended Planning Area, covers 24.9 square miles, 9 square miles of which are currently in the city. 1 - 1 General: Because it is long-range and comprehensive, the plan must be general. Neither time nor knowledge exist to make it detailed or specific. The plan's purpose is to serve as a framework for detailed public and private development proposals.

As mentioned in the Introduction, policies for the Extended Planning Area are being formulated through general plan amendment and specific plan studies currently underway for the Western and Eastern Extended Planning Areas. These documents are expected to be completed in 1992.

A Community Workshop held in July 1983 attracted about 25 participants in addition to most members of the Commission and Council. General Plan discussions were thorough, usually lasting more than four hours, but the number of public participants was small - probably because most residents in a nearly built -out community do not expect the plan to have major effects on their lives or property. During the same period, hearings on several controversial medium or medium -high density residential projects drew large audiences. 1 - 3 1.8 GENERAL PLAN MAP The General Plan Map for the Primary Planning Area proposes an arrangement of land uses and a circulation system to serve those uses at full development - expected to occur within 10 years. Because so little land remains uncommitted, boundaries between uses are exact. However, deviations in road alignments or open space configurations, and request for approval of churches or other semi-public facilities typically appropriate to the adjoining uses are not to be considered inconsistent with the General Plan. Both the map and the text should be consulted to determine consistency or inconsistency.; -the -text -shall govern. (See Figure 1) 1.8.1 Land Use Classification The following descriptions are intended to aid interpretations of the General Plan map legends. Density Measurements Density measurements for General Plan purposes are based upon gross residential acreage and is calculated as follows: Gross residential acreage (GRA) shall be determined by calculating the area of the site and by adding one-half of the area of abutting streets, provided that the street width used for calculation shall not be less than 25 feet or more than 50 feet. Public or private streets within the boundaries of the site, as well as streets abutting the site, are calculated within the gross acreage total. Gross acreage, rather than net acreage, is used as a General Plan density measurement in order to account for situations in which larger multiple family and Planned Development residential projects include much vehicular circulation area that is not public right-of-way. In such cases, the project site area would be larger than on smaller, conventional sites that rely mainly on dedicated streets for access. If allowable densities were calculated on the site area or net acreage basis, the larger projects would have higher "effective" densities than the smaller sites. Example: Ponderosa Village General Plan designation = single-family residential (0.9 to 6.0 units per gross residential acre). 89 dwelling units (DU) 12.20 net acres (average lot size = 5,970 square feet) 3.13 street acres (20% of gross residential area) 15.33 gross residential acres (GRA) Project density = 5.8 DU/GRA 1 - 5 requirements and typically result in .35 to .40 FAR's. Examples: Clark Avenue, Sierra Court. Business Park/Industrial: Outdoor Storage (FAR: .25 to .40; employee density: 360-490 square feet per employee.). In addition to the Business Park/Industrial uses described above, this classification includes retail and manufacturing activities conducted outdoors such as mobile home or construction materials storage. Example: Scarlett Court. Public/Semi-Public (FAR: .50; employee density: 590 square feet per employee) Public/Semi-Public Facilities. Uses other than parks owned by a public agency that are of sufficient size to warrant differentiation from adjoining uses are labeled. Development of housing on a site designated on the General Plan as semi-public shall be considered consistent with the General Plan. Determination as to whether housing should be permitted on a specific semi-public site and the acceptable density and design will be through review of a Planned Unit Development proposal under the Zoning Ordinance. Examples: Public and private schools, churches, Civic Center. Parks/Public Recreation. Publicly owned parks and recreation facilities. Open Space. Included are areas dedicated as open space on subdivision maps, slopes greater than 30 percent, stream protection corridors, woodlands, and grazing lands. Extended Planning Area (See Figure 1-2) Residential and Open Space See General Plan Map and Sections 2.1.4, 3.1, 3.2, and 3.3. Commercial/Industrial Business Park/Industrial: Low Coverage (FAR: .25 to .40; employee density: 360-490 square feet per employee). This classification is intended to provide a campus -like setting with open plazas and landscaped pedestrian amenities for the uses described in the Business Park/Industrial classification for the Primary Planning Area and to allow retail uses to serve businesses and residents.

A land use element must first designate the proposed distribution of specified uses and facilities. It must identify population density and building intensity standards for each land use district. It must identify areas subject to flooding and review those areas annually. Finally, it must create a timber production land use category where appropriate. Each of these required features is included in Dublin's adopted General Plan, although not all are present in the land use element. Dublin's General Plan Maps for the Primary and Extended Planning Areas, Figures 1-1 and 1-2, summarize the proposed distribution of residential, commercial, industrial, and open space uses. The maps also show existing schools and other public buildings and grounds. Policies further defining the location and intensity of residential, commercial, and industrial uses appear in this land use element. Policies relating to open space and kparks appear in the Parks and Open Space Element, sec. 3.0; while policies relating to schools, and solid and liquid waste disposal facilities appear in the Schools, Public Lands and Utilities Element, sec. 4.0. Background information supporting the adopted policies is located in the corresponding Land Use, Open Space, and Schools, Public Lands and Utilities sections of the Technical Supplement. Population Density and building intensity standards are presented in sec. 1.8.1. of General Plan Volume 1. Areas subject to flooding and appropriate land use policies are presented in sec. 8.2 of the Seismic Safety and Safety Element. Dublin's General Plan contains no timber production land use category because no timberland as described in Government Code sec. 65302(a) occurs anywhere in the city's planning area. Because Ninety-nine f99)- percent of the primary planning area has been developed since 1960 or has development approvals; therefore, the Land Use Element focuses on the remaining uncommitted sites and on the potential for more intensive use of existing sites. Land use changes in the extended planning area will be more dramatic, but urban development there is likely to occur mainly after the mid-1990's. The primary planning area is expected to be built -out within ten years, (1994) adding a potential 3,500 housing units, 8,400 residents, and 2,400 jobs to the 1983 totals. Except for downtown intensification, the General Plan does not envision highly visible changes in Dublin's primary planning area, but it does provide for more than a 60 percent gain in population.

(Based on data contained in the 1990 Housing Element) 2Totals rounded. 2.1.3 Residential Compatibility Guiding Policy A. Avoid abrupt transitions between single-family development and higher density development on adjoining sites. Implementing Policies B. Require all site plans to respect the privacy and scale of residential development nearby. C. Require a planned development zoning process for all development proposals over 6.0 units per gross residential acre. 2.1.4 Extended Planning Area Guiding Policy A. Consider residential development proposals (including support facilities such as neighborhood shopping centers, schools and parks) on moderate slopes, with multi -family densities typically considered on flatter land and next to business park areas. Many potential sites are under Williamson Act contract requiring open space use for at least 10 years. A number of urban design improvements are contemplated including entry ways to downtown, theme elements in the medians and a potential plaza or structure which would be used as an informal gathering place as well as for public and civic events. (Refer to the plan for further details. Available from the City of Dublin Planning Department.) Implementing Policies B. Designate a Downtown Intensification Area on the General Plan Land Use and Circulation map, Figure 1-1. C. Provide a downtown BART station that will serve customers and workers with and without cars. Add offices and apartments within walking distance and eventually over BART parking. D. Encourage mid -rise office/apartment buildings and parking structures with ground floor retail space. Create store -lined pedestrian connections between existing shopping centers. E. Make downtown more understandable to the first-time visitor by installing standardized identification signs and directories. seon- 2.2.2 Automobile Dealerships Guiding Policy A. Keep automobile dealers in Dublin. Implementing Policy B. Allow for the creation of an auto center east of Camp Parks Military Reservation. If or when downtown land becomes too costly for car dealers they will have the opportunity to relocate in an auto center with freeway frontage. 2.2.3 Neighborhood Shopping Centers Guiding Policy A. Strengthen existing neighborhood shopping centers. Competition from downtown and from north of the County line leaves no trade area within the primary planning area for neighborhood shopping centers other than Dublin Square, San Ramon Village Plaza, and Village Square.

Government Code sec. 65560 calls for an inventory of open space resources and for policies to preserve and manage four categories of open space lands: (1) Open space for the preservation of natural resources. (2) Open space for the managed production of resources. (3) Open space for outdoor recreations. (4) Open space for public health and safety. Government Code sec. 65564 requires local open space plans to include action programs with specific programs to implement open space policies. Public Resources Code sec. 5076 requires that demand for trail oriented recreational uses be considered when developing the open space programs. It further requires that the open space plan consider integrating local trails with the state trails system. Policies and programs to provide oTen space both within and apart from development projects are included in this parks and open space element. Related provisions to protect particular natural resources through open space planning are included in sec. 7.0, Conservation Element. Background information upon which open space and conservation policies are based is located in the corresponding Open Space and Conservation sections of the Technical Supplement. The Government Code requires discussion of several resources which do not occur in the Dublin planning area and therefore, have not been analyzed. Accordingly, the open space plan for preservation of natural resources does not address ecological or scientific study areas, bays, estuaries, coastal beaches or lakeshores. Similarly, the open space plan for managed production of resources does not address bays, estuaries, marshes, commercial fisheries, or mineral deposits. Flooding is addressed in the Safety Element, section 8.2.3. 3.1 OPEN SPACE FOR PRESERVATION OF NATURAL RESOURCES AND FOR PUBLIC HEALTH AND SAFETY Subsequent to adoption of this general plan, the City began preparation of specific plans for the Extended Planning Area. These documents should be completed by the end of 1992. Refer to these documents for specific information on open space, parkland and recreation facilities in the Extended Planning Area. 3 - 1 The City's existing trail network consists of bikeways located along Amador Valley Boulevard, Village Parkway, San Ramon Road and Dougherty Road.

This plan updates and quantifies the City's need for recreation facilities. It is expected this plan will be comileted in 1992. Readers should refer to this plan for additional information on city park and recreation facilities, as well as action and acquisition programs. Guiding Policies A.

Dublin has included these three concerns in a separate element because they generally are operated by independent units of government, whereas most of the other development related concerns addressed in the statutes involve city regulation. Information supporting the schools, public lands and utilities policies is located in the Technical Supplement, sec. 2.3. 4.1 PUBLIC SCHOOLS Enrollment in the Dublin Unified School District has been increasing since 1990 with a current enrollment of 3206 students Murray-Seheel Bistriet-{grades-K-8)--has-been-declining-since-1973. Currently, three K-65 schools (Nielsen, Murray and Frederiksen Cronin) and one two 67-8 schools (Wells Middle School), one high school (Dublin High School, 9- 12) and one continuation high school (Valley High School, 10-12) and Frederieksen} accommodate Dublin students.

Initiate preparation of site plans or specific plans jointly with the Dublin Unified School District prior to sale. D. As a condition of project approval in the Extended Planning Area, it is required that logical and buildable school sites be offered for dedication according to the State's Board of Education guidelines and acceptable to the Dublin Unified School District. planning process to require each jurisdiction to prepare a Source Reduction and Recycling Element and a Household Hazardous Waste Element. While these elements are not required to be part of a city's general plan, planning policy nevertheless should be guided by the elements since solid waste disposal is a necessary service for new development. The City of Dublin currently has a Franchise Agreement with Oakland Scavenger Company for residential and commercial garbage collection. Solid waste is deposited at the Altamont Landfill. The owners of the landfill are currently pursuing an expansion which would provide 350 million cubic yards. As of March 1992, estimated remaining capacity at the landfill is 24.5 million cubic yards. This is anticipated to provide landfill capacity for eight years. This assumes a countywide increase in the amount of solid waste disposed of at 0.8 percent per year. Guiding Policy A. Ensure that adequate solid waste disposal capacity is available to avoid constraining development consistent with the Dublin General Plan. Implementing Policies B. Continue to enforce the City Source Reduction and Recycling/ Household Hazardous Waste Elements. C. Cooperate with Alameda County, as necessary, for adoption and implementation of the County Solid Integrated Waste Management Plan. D. Prior to project approval, the applicant shall demonstrate that capacity will exist in solid waste disposal facilities for their project prior to the issuance of building permits. E. Large scale projects should be required to submit a plan that demonstrates how they will contribute toward the City's State mandated diversion requirement. 4.4 SEWAGE TREATMENT AND DISPOSAL Sewage treatment and disposal capacity for the City of Dublin is limited. The existing Dublin San Ramon Services District (DSRSD) sewage treatment plant adjoining I-680 in Pleasanton could be expanded to four times its present size, but the Livermore Amador Valley Water Management Agency (LAVWMA) pipeline that carries treated effluent from Livermore, Pleasanton and Dublin through Dublin Canyon to the Bay is nearing capacity. Currently, approximately 2,900 dwelling unit equivalents of wastewater capacity are available on a first -come, first -serve basis. The Tri-Valley Wastewater Authority is working to obtain additional capacity from the Central Contra Costa Sanitation 4 - 3 5.0 LAND USE AND CIRCULATION SECTION: CIRCULATION AND SCENIC HIGHWAYS ELEMENT 5.1 TRAFFICWAYS Government Code sec. 65302(b) requires that circulation elements include diagrams, policies and programs for existing and proposed major thoroughfares, transportation routes, terminals and other public utilities and facilities. The statute further requires that these circulation and public services features be correlated with the land use element. That is, the General Plan must propose circulation and public services adequate to meet the needs of the population planned for in the land use element. Dublin's proposed road system for the Primary Planning Area is shown on Figure 1-1, the General Plan map for Land Use and Circulation. Proposed traffic and roadway volicies are presented below in this element. Information supporting the policies is located in the Technical Supplement, sec. 2.4, Circulation and Scenic Highways Element. The -prepared -road -system -and -planning -policies -will -be determined -through -the -East -and -West -Dublin -Extending -Planning -Area Speeifie-Plan-Studies-for-the-Extended-Planning-Area.- The policies and standards in this element also pertain to the extended planning areas. In addition, the general plan amendment and specific plan studies being prepared for the Eastern and Western Extended Planning Areas should also be consulted for guidance on circulation. These documents are expected to be completed in 1992. Proposed public utilities and facilities are addressed in sec. 3.0, the Parks and Oven Space Element, and in sec. 4.0, the Schools, Public Lands, and Utilities Element. Information supporting these policies is located in the Technical Supplement, sec. 2.2, Open Space Element and sec. 2.3, Schools, Public Lands and Utilities Element. The street network described in this Circulation Element was designed to accommodate peak period traffic demand and minimize excessive delays and congested conditions during peak hours. The street design standards specify the width and other design features necessary to ensure there is sufficient roadway capacity to accommodate future travel on Dublin streets. Guiding Policy A. Design streets to accommodate peak period traffic demand and minimize congested conditions during peak hours of operation. Implementing Policy B. Design streets according to the standards set forth in paragraphs 1 through 8 below, as well as the listed Additional Design Criteria. If average daily traffic (ADT) is greater than the stated approximate maximum ADT, design the street to a higher functional classification, per approval of the City Engineer. 5 - 1 Major streets are primarily designed to distribute localized trips. Typically, intersections with median openings shall be spaced no closer than 660 feet. Any other intersections without median openings may be approved by the City Engineer. A raised median is required to separate the two directions of travel and to improve the visual appearance of the arterial corridor. Akproaches to intersections shall be widened as required by the City Engineer in order to provide for additional lanes for left turn and right turn movements. Access to and from four -lane major streets from abutting commercial properties shall be controlled but not restricted. No direct access from single-family residential homes is allowed. Parking on these facilities shall be prohibited with the exception of emergency parking. Bike lanes shall be provided. Pedestrian crossings should be carefully selected to direct pedestrians to designated crossing points at signalized intersections. EXAMPLES: San Ramon Road from Amador Valley Boulevard to Alcosta; Village Parkway, and Amador Valley Boulevard, west of Village Parkway. 3. CLASS I COLLECTOR STREETS Design ADT 27,000 Minimum design speed 45 mph Curb -to -curb 76' Right-of-way 92' Maximum grade g% Minimum Curve Radius 1,100' with no superelevation Public utility and landscaped buffer area easement 10' on each side of right-of-way Class I collector streets serve primarily to circulate localized traffic and to distribute traffic to and from arterials and major streets. Class I collectors are designed to accommodate four lanes of traffic; however, they carry lower traffic volumes at slower speeds than major streets, and they have a continuous left turn lane separating the two directions of traffic flow. Typically, intersections shall be spaced no closer than 660 feet unless otherwise approved by the City Engineer and potential signalized intersections shall be spaced at intervals of 660 feet. Medians shall be striped in special cases if no abutting property access is allowed (minimum of a mile), the striped median can be reduced to 4 feet with approval of the City Engineer. Left turns into driveways near an intersection (200') will be prohibited by a raised median. EXAMPLES: None yet existing in Dublin. 5 - 3 streets accommodate low volume levels and the use of this facility as a carrier of through traffic should be discouraged by its design. Minimum distance between intersections shall be 250 feet. Deviation from this minimum distance requirement may be approved by the City Engineer only if it can be demonstrated that left turn demands do not create adverse traffic conditions. Parking on this facility shall typically be allowed. However, parking at critical locations may be denied as deemed appropriate by the City Engineer. If a bike lane is provided on this facility and parking is retained, an additional 10 feet of right- of-way will be required to allow for a 10-foot widening of the roadway cross section. EXAMPLES: York Drive, Vomac Road 6. RESIDENTIAL STREETS Design ADT Minimum vertical design speed Curb -to -curb Right-of-way Maximum grade Minimum curve radius Public utility and landscaped buffer area easement 1,500 25 mph 36' (32' single loaded) 52' (45' single loaded) 12%* 200' with no superelevation 10' on each side of right-of-way *Maximum grade up to 15% may be allowed under special conditions and approval by the City Engineer. Grade_ segments in excess of 12% shall not exceed 300 feet in length. Average grade over any 1,000 foot segment shall not exceed 10%. Residential streets circulate localized traffic as well as distribute traffic to and from arterials and collectors to access residential areas. Residential streets accommodate low volume levels and should not be used to carry through traffic. Minimum distance between intersections shall be 150 feet. Deviation from this minimum distance requirement may be approved by the City Engineer only if it can be demonstrated that left turn demands do not create an adverse traffic condition. Examples: Beverley Lane, Ironwood 5 - 5 minimum of 200 feet and maximum grade of 6% from the point of curb return (PCR) on each leg of the intersection except as approved by the City Engineer. The tangent length of 200 feet is not required for residential streets intersecting another residential or collector street if an adequate intersection sight distance is provided. 4. Intersection sight distance shall meet CalTrans Highway Design Manual criteria. 5. A minimum of one on -street parking space (20 feet) shall be provided along the frontage of each residential lot. However, in cases where the minimum on -street parking space requirement cannot be met, credit shall be given for surplus on -street parking in front of nearby lots upon approval of the City Engineer. With approval of the City Engineer, residential lots which provide three or more off-street parking spaces shall be exempt. 6. No gates or controlled access devices or private street. are allowed on any public 7 Compound curves shall not be allowed. 8. All box -landscaped planters along a raised median shall be placed no closer than 3 feet from the face of the median curb. The I-680 freeway is to be widened to eight lanes within the years and the freeway to freeway interchange will be rebuilt freeways and the arterial street system experience heavy new from development in adjoining communities. Guiding Policy C. Improve Implementing D. Provide provide freeway access. Policies an additional better access next five as both demands interchange on I-680 north of I-580 to to the downtown area. B--.-Add-an-I-680-interchange-at-er-xear-Amadar-Vallep-Beulevard- Access to downtown from the north and south along Interstate 680 is needed at a point closer than Alcosta Boulevard. The entire central portion of the City needs an alternative to congested Dublin Boulevard intersections at San Ramon Road and Dougherty Road. E. Work with the City of San Ramon to increase the capacity of the Alcosta Boulevard interchange. This may be achieved by relocating southbound I-680 ramps to intersect San Ramon Road north of Alcosta. 5.2 TRANSIT BART currently operates two bus lines serving BART rail stations and providing limited local transit service. Dublin taxpayers have been paying their full share for direct rail service as shown on the original BART plan, but other extensions competing for funding have received stronger support from the Metropolitan Transportation Commission staff. The rail service proposal was revised in 1983 to indicate BART in the I-580 freeway median with stations in downtown Dublin (West Dublin/Pleasanton station) and at Hacienda Drive (East Dublin/Pleasanton station). The Pleasanton/Dublin Short Range Transit Plan (December 1983) proposes a nine -bus fleet providing local service on routes within three blocks of 85 percent of Dublin's residents. Guiding Policies A. Support a compact multi -story downtown BART station and a second station to the east along I-580, provided the BART rail line is extended at least to the eastern limits of the City of Pleasanton. B. Support improved local transit as essential to a quality urban environment, particularly for residents who do not drive. Implementing Policies C. Urge BART cooperation in maintaining availability of station sites and develop standards for review of public and private improvements in the vicinity of BART stations that take account of both future traffic needs and development opportunities. D. Pursue formation of a Joint Exercise of Powers Agreement with neighboring jurisdictions to enable use of Transportation Development Act funds to begin improved local transit service late in 1984. The proposed bus loop would start at San Ramon Road and Dublin Boulevard, proceeding via Dublin Boulevard, Hansen Drive, Silvergate, Peppertree, Shannon, San Ramon Road, Alcosta, Davona, Village Parkway, Amador Valley Boulevard, Dougherty Road, Dublin Boulevard, and San Ramon Road, to Stoneridge and Pleasanton. 5.3 SOUTHERN PACIFIC RAILROAD RIGHT-OF-WAY TRANSPORTATION CORRIDOR Contra Costa and Alameda Counties are considering means of preserving the Southern Pacific right-of-way. Track has been removed from the San Ramon Branch line between Pleasanton and Pleasant Hill. Recent studies have proposed future use for light rail transit or as a busway. 5 - 9 5.6 SCENIC HIGHWAYS 1-580, I-680, San Ramon Road, and Dougherty Road were designated scenic routes by Alameda County in 1966. These are the routes from which people traveling through Dublin gain their impression of the city; so it is important that the quality of views be protected. In the Eastern Extended Planning Area, Tassajara Road and Doolan Road are designated by Alameda County. Guiding Policy A. Incorporate previously designated scenic routes in the General Plan and work to enhance a positive image of Dublin as seen by through travelers. Implementing Policy B. Exercise design review of all projects within 500 feet of a scenic route and visible from it. 5.7 FINANCING ROAD IMPROVEMENTS The City has a five year Capital Improvement Program (CIP) which includes a section on streets. The most recent CIP (1991-92) lists 17 street improvement projects along with estimated costs and financing schedules. The monies to fund these projects come from several sources including the City's operating budget, state/federal funds, development fees, grants and loans. (A copy of the Dublin 1991-92 CIP program is available from the City Manager's Office.) Currently, development plans are being formulated for the Eastern and Western Extended Planning Areas. Construction of necessary roads will be funded by the developers. Developer contributions will also be required for existing city roadway projects which will be impacted by traffic from developments in the extended planning areas.

This document entitled "City of Dublin General Plan Housing Element" is available from the City of Dublin Planning Department. 6 - 1 7.0 ENVIRONMENTAL RESOURCES MANAGEMENT SECTION: CONSERVATION ELEMENT Government Code sec. 65302(d) requires that conservation elements plan for the conservation, development and use of natural resources. The statute lists resources that must be included and suggests other resources that may be included in the element. Finally, the statute specifically requires that countywide and any other water development, control or conservation agencies be included in the element's water analysis. Dublin's Conservation Element addresses the following statutorily required elements: water resources, agricultural ana other soils, rivers and streams, and wildlife habitats. Other important resources discussed in this element are air quality and archaeological and historical resources. Many conservation related resources are also important in the context of other elements. For example, agricultural and other open spaces are discussed in sec. 3.0 Parks and Open Space and sec. 4.0 Schools, Public Lands and Utilities Elements. Soil conditions related to earthquakes and flood hazard from local streams are discussed in sec. 8.0 Seismic Safety and Safety Element. Each of these elements' counterparts in the Technical Supplement may also be consulted for information and background on resource related planning policies. Still other statutorily required resources do not occur in Dublin's planning area and are therefore not discussed. Specifically, Dublin is an inland city which contains no artificial or natural harbors. Likewise, the planning area contains no fisheries nor mineral extraction areas. Air quality and wastewater disposal have been the Tri-Valley's most difficult conservation issues affecting urban growth, even with construction of the Livermore Amador Valley Wastewater Management Association (LAVWMA) pipeline, and significantly improved air quality. The extent of anticipated development now draws greater attention to other conservation issues -- conversion of agricultural land to urban uses; loss of open space; hazards posed by development in steep and landslide -prone areas; increased runoff; and erosion and stream siltation. Additionally, the prospect of renewed or intensified air quality and sewage disposal problems accompanies plans approved or under consideration that would result in up to 200,000 jobs in the Tri- Valley. open-spaee-resourees-are-discussed-in-the-open-spaee-element;-the seismie-safety-and-safety-elements-eonsider-natural-hazards- This-section-and-its-eounterpart-in-the-Technicai-Supplement eensider-hydrology;-habitats;-agricultural-open-spaee;-air;-sail reseurees7-and-arehaeoiagieai=and-historic-resourees7 7 - Eastern Dublin Environmental Setting - November, 1988 Eastern Dublin Specific Plan, General Plan Amendment and Environmental Impact Report - to be published in 1992 Guiding Policies A. Protect riparian vegetation as a protective buffer for stream quality and for its value as a habitat and aesthetic resource. B. Promote access to stream corridors for passive recreational use and to allow stream maintenance and improvements as necessary, while respecting the privacy of owners of property abutting stream corridors. Implementing Policies C. Enforce watercourse ordinance in developed areas of city. D. Require open stream corridors of adequate width to protect all riparian vegetation, improve access, and prevent flooding caused by blockage of streams. E. Require revegetation of creek banks with species characteristic of local riparian vegetation, where construction requires creekbank alteration. F. Complete and adopt the Western and Eastern Dublin General Plan Amendment and Specific Plan Studies in a timely manner. 7.2 EROSION AND SILTATION CONTROL Guiding Policies A. Maintain natural hydrologic systems. B. Regulate grading and development on steep slopes. Implementing Policies C. Enact and enforce erosion and sedimentation ordinance establishing performance standards in relation to maintenance of water quality and protection of stream courses. D. Enact ordinance requiring on -site runoff control. E. Review development proposals to insure site design that minimizes soil erosion and volume and velocity of surface runoff. F. Restrict development on slopes of over 30 percent. 7 - 3 the original Murray School House the old St. Raymond's Church the Alviso Adobe The Amador Adobe The Green Home and The Palomares School Refer to City of Dublin Technical Supplement, January, 1985 for additional information on historic resources in Dublin.-ehurch and-seheol-an-the-grounds-Of-the-heritage-park. B. Follow State regulations -- Public Resources Code Sections 21083.2(c) and (d) -- regarding discovery of archaeological sites, and Historic Resources, as defined in Section 5020.1 of the Public Resources Code. 7.7 OPEN SPACE MAINTENANCE/MANAGEMENT Acquisition of existina open space has been accomplished through Planned Developments and subdivision approvals. Since the existing City is mostly built out, there will be no additional major areas set aside for open space. In the Western and Eastern Extended Planning Areas, substantial amounts of open space will be designated for open space. Refer to the Western Dublin Specific Plan for additional information. The Specific Plan for eastern Dublin is expected to be completed in 1992. It will contain designated areas of open space and mechanisms for maintenance and management. In addition, the City's Park and Recreation Master Plan (to be completed in 1992) will contain information on open space acquisition and maintenance. Guiding Policy A. Require open space management and maintenance programs for open space areas established through subdivisions and Planned Development districts. Programs should include standards to ensure control of potential hazards; appropriate setbacks; and management of the open space so that it produces a positive and pleasing visual image. Implementing Policy B. Require that land designated as open space through development approval be permanently restricted to open space use by recorded map or deed. C. Require reveaetation of cut and fill slopes. D. Require use of native trees, shrubs and grasses with low maintenance costs in reveaetation of cut and fill slopes. 7 - 5 8.0 ENVIRONMENTAL RESOURCES MANAGEMENT SECTION: SEISMIC SAFETY AND SAFETY ELEMENT 8.1 SEISMIC SAFETY Government Code sec. 65302(q) requires safety elements to propose policies and programs to protect communities from unreasonable seismic, geologic, flooding and fire risks. The statute requires that seismic and geologic hazard areas be mapped. It also requires the element to address evacuation routes, peakload water supply, minimum road widths and structural clearances for geologic and fire hazards identified in the element. Accordingly, Dublin's Seismic Safety Element assesses the risk of ground shaking, rupture, and failure due to earthquakes. The element discusses landslide, subsidence and liquefaction hazards. It also discusses flooding, and urban and wildland fires. Related discussion and analysis of these hazards is located in the Technical Supplement, sec. 4.1 Conservation Element and sec. 4.2 Seismic Safety and Safety Element. The planning area offers examples of most of the geologic hazards commonly found in California, but only two -- downslope movement (mainly landslides) and earthquake fault surface rupture -- are significant constraints on the location of urban development. Downslope movement includes landslides, rockfalls, debris flows, and soil creep. Factors affecting downslope movement are groundwater, rock and soil type, slope angle, propensity to erosion, seismic activity, vegetation, and grading or other human alterations. The Calaveras Fault is the major active fault in the planning area with rupture potential and runs parallel to and just west of San Ramon Road. The Pleasanton Fault, near the west edge of Camp Parks, is difficult to locate precisely. The State has established Alquist-Priolo Special Studies Zones along both faults, requiring detailed studies of rupture hazards prior to construction. Few potential building sites within the City of Dublin or the extended planning area are without geologic impact or hazard. The hazard may be actual, such as an active landslide or proximity to an active fault, or potential, such as a proposed cut that might activate a landslide. Mitigation of hazards may increase construction cost, but will reduce long-term costs to both property owners and the city. 8 - 1 - cumulative effect of new development on a partially developed slide; effects of septic leach systems, garden watering, and altered drainage patterns; - impact of a maximum credible earthquake; - where applicable, passage of the Calaveras Fault through or under landslide deposits; - debris flow and other downslope hazards (especially common east of Dublin). Care must be taken not to locate structures in the path of potential debris flows. - Where published maps identify or show "ancient" or Quaternary slides on sites of proposed development, their stability must be analyzed, and effects of the proposed development on the area's stability must be evaluated by a soils engineer. C. If the preliminary report indicates liquefaction potential, an engineering analysis and design, if necessary, to mitigate liquefaction hazards, shall be required for all structures planned for human occupancy. D. Evaluation for shrink -swell potential shall be included with all soils reports and design recommendations formulated where the potential is present. These analyses and recommendations shall include public streets and utilities, in order to reduce future public repair costs. E. A fault rupture evaluation, as outlined by the State of California for Special Studies Zones (Alquist-Priolo Act), shall be required for all development within the Revised Special Studies Zones as shown on the Geologic Hazards and Constraints map. The fault rupture evaluation should be conducted after building sites are specifically defined. Sites situated outside of this zone but within the Preliminary Zones (Slossen, 1973) shall be evaluated if proposed for multi -family dwellings or for public or recreational facilities. F. Any changes in grading or building design that would be significantly affected by geologic hazards or soils conditions, or in turn would significantly alter geologic or soils conditions, shall be accompanied by a re -analysis of those conditions. In addition, any conditions discovered during excavation or grading that significantly depart from the previously described geologic and soils setting shall be evaluated. 8.1.3 Existing Structures A. Post -earthquake or damage reconstruction of existing structures shall be permitted only if mitigating factors are incorporated. San Ramon Services District (DSRSD) supplies water to the City of Dublin. Currently, the District has a capacity of 10,500 gallons per minute. On a peak day, 5,250 gallons per minute is used for domestic purposes, leaving 3,750 gallons per minute for fire fighting or other uses. According to the Fire Authority, there has been sufficient water to accommodate fire calls in the City of Dublin. (Personal Communication, Harold Ritter, former Fire Chief, Dougherty Regional Fire Authority, January 23, 1992.) Steep, inaccessible slopes and brush create a high fire hazard in the western hills. Major personnel and equipment additions would be needed to protect development in the extended planning area. DRFA DSRSD does currently provide protection to Camp Parks Military Reservation and to Santa Rita Rehabilitation Center under contract with the County of Alameda. and -is -not -able -to serve -these -areas -at -present - Guiding Policy A. Require special precautions against fire as a condition of development approval in the western hills outside the primary planning area. Implementing Policies B. A fire protection buffer zone shall be provided around the perimeter of residential development situated adjacent to undeveloped open space land. 87C. Enact a high hazard ordinance specifying Fire -retardant -roof -materials; -spark -arrestors; -water storage;-and-vegetation-elearance-around-structures: Sprinklers for all habitable structures beyond five minutes response time from a station. D. Continue to enforce the City's Fire Safe Roof and Spark Arrestor ordinances. Guiding Policy e7E. Prepare and implement a plan for facilities and personnel at one or more fire stations east of Tassajara Road as a condition of development approval in the Eastern Extended Planning Area. 8.2.3 Flooding Figure 8-2 delineates flood prone areas in the existing City limits. The areas shown identify the 100 and 500 year flood zones. Since this map was published, the City has implemented some downstream improvements and the map will ultimately be amended by the Flood Emergency Management Agency. 8 - 5 8.2.4 Hazardous Materials Hazardous materials are transported on the freeways and some are used by Dublin industries. DSRSD, Fire Department and the Dublin Police Department form the City's hazardous materials team. Guiding Policy A. Maintain and enhance ability to regulate use, transport, and storage of hazardous materials and to quickly identify substances and take appropriate action during emergencies. Implementing Policy B. Consider formation of a hazardous materials team consisting of specially trained personnel from all Tri-Valley public safety agencies. C. Implement the Alameda County Hazardous Waste Management Plan, when it is approved by the State. D.C.- Adopt an ordinance to regulate handling, transport, and storage of hazardous materials and hazardous waste.

Recognizing the State Office of Noise Control (ONC) guidelines, noise elements must quantify current and projected noise levels for local noise sources. Among the noise sources to be evaluated are highways, freeways, arterials and major streets, railroads and rapid transit systems, airports and heliports, industrial plants, and any other local sources. Traffic noise and potential light rail noise are the only major noise sources in Dublin's planning area. The focus of this noise element, therefore, is the effect of traffic and transit noise on locating categories of land use and developing projects within those categories. Information supporting the adopted noise policies is located in the corresponding Noise Element section of the Technical Supplement. The planning area contains no railroads, airports, heliports or industrial plants. Since these noise sources are not a factor in Dublin's planning, they are not addressed. Traffic is the primary source of continuous noise in Dublin. Noise exposure contours have been plotted for 1983 (based on noise measurements and current traffic data) and projected to 2005 based on traffic volume increases (see Figures 9-1 and 9-2). The Community Noise Equivalent Level (CNEL) described 24-hour average noise levels measured in decibels (dB) taking account of the increased sensitivity of people to noise during evening and nighttime hours. Sound levels between 7:00 and 10:00 p.m. are penalized 5 dB and those between 10:00 p.m. and 7:00 a.m. are penalized 10 dB. The dB scale is logarithmic; a 3 dB difference normally is discernable and a 10 dB increase is subjectively heard as a doubling in loudness. The other potential significant noise source is the two proposed BART stations. Based on best available information (as of January 1992) one station will be located in downtown Dublin, near existing commercial development. The other station will be located on Alameda County property, west of the Hacienda interchange. Noise impacts from these two stations were addressed in the "Draft Environmental Impact Report - Dublin/Pleasanton Extension Project," September 1989. This document was certified on February 8, 1990. A copy of this document is available from the City Public Works Department. No areas near the Dublin stations were identified where noise or vibration would exceed acceptable standards. The Land Use Compatibility Table provides the basis for decisions on location of land uses in relation to noise sources, and for determining noise mitigation needs. For noise issues in the Western and Eastern Dublin Extended Planning Areas, refer to the 9 - 1 Noise impacts related to all new development shall be analyzed by a certified acoustic consultant. Conditionally acceptable exposure requires noise insulation features in building design. Conventional construction, but with closed windows and fresh air supply systems or air conditioning will normally suffice. Source: California Office of Noise Control, 1976, as modified by Charles M. Salter Associates, Inc. G. Request demonstration of ability to mitigate noise prior to approval of light rail or bus service in the Southern Pacific Right -of -Way Transportation Corridor. A depressed rail line or noise walls close to the tracks could make light rail a good neighbor. Review all multi -family development proposals within the projected 60 CNEL contour for compliance with noise standards (45 CNEL in any habitable room) as required by State law. Because the General Plan designates almost all residential sites subject to 60 or greater CNEL for multi -family development, this standard will be effective in Dublin. Project designers may use one or more of four available categories of mitigation measures: site planning, architectural layout (bedrooms away from noise source, for example), noise barriers, or construction modifications.
