(Dublin Zoning Ordinance Section 8.36.100) Subject to Building Code requirements for access. The 3ra floor must be stepped back from front and rear elevation to reduce building mass. Where 50% or more of the elevation of the home is a single story element and there is a 5' minimum offset between the 1st and 2nd story elements, the setback for the single story and 2- story elements shall be considered as that for a single story building. Three car front-on garages are prohibited on lots within the F1 Neighborhood. In the F2 Neighborhood, three car front-on garages are limited to one plan per neighborhood plan package. Refer to Building Mass and Form and Architectural Treatment Sections of the Architectural Design Standards for additional architectural requirements pertaining to garage fagade, roof lines, etc. Swing-in garages are prohibited on lots less than 55' wide. Retaining walls up to 3' high may be used to create a level usable area. Retaining walls in excess of 3' to create usable area are subject to review and approval of the Building Official or Community Development and Director of Public Works. Wails over 30" in height are subject to safety criteria as determined by the Building Official. Setbacks subject to review and approval of Building Official for Building Code and Fire Code issues. Setback to building overhang to be 3' minimum or as required by current City Building Code Standards. Where a minimum 5' wide Homeowners Association (HOA) parcel lies between a lot and an adjacent street the adjacent lot is not considered a corner lot. At cul-de-sac bulbs where lot depths are less than the standard 100', minimum rear yard setback requirements may be reduced by an amount equal to 100' minus the actual depth of the lot (i.e. 100' - 90' = 10'). In no case will the rear yard setback be reduced to less than 10'. Curbside parking may be counted toward required number of guest spaces.

These standards have been developed to establish pedestrian-friendly neighborhoods with variety and interest and uphold a high level of quality and value in the overall community. The goal for these neighborhoods is to achieve a safe and pleasant neighborhood environment within ~vhich varied architecture, reduced dominance of automobiles, pedestrian scaled landscapes and walkways and connections to other community areas are all present. Relative to this document is Attachment A - "Architectural Style Guidelines" which is intended to further define the architectural design intent of this project. This attachment can be found following the Architectural Design Standards of this PD document. NEIGHBORHOOD DESIGN Neighborhood Plotting and Massing One important goal of these guidelines is to create a functional street scene possessing visual quality and variety. Plotting and design criteria are intended to provide this variety in appearance as well as a sense of individuality for each home. Projects where nearly identical buildings line streets without variation in placement and architectural form are not permitted. This and the following section lists plotting and massing techniques which will aid in the creation of a successful street scene. While it is not necessary that every method be utilized, selective and appropriate use will greatly contribute to achieving the desired results. 11 - 1 Architectural Design Sta~tdards Dublin Ranch Area F North · .lune 2003 The following techniques address the use of plotting and massing to improve the street scene: · Reversing and varying adjacent house plan forms. · Avoiding obviously repetitious patterns. · Opening corner lots through plan selection and reduced building heights. · Varying setbacks. · Giving attention to composition of building mass. · Incorporating single story elements into two story buildings. · Stepping second stories. · Minimizing ¥isual impact of the garagc. Architectural Plan and Style Mix In order to achieve varied and interesting street scenes, the following architectural style mix and plan requirements must be met: In each neighborhood provide: Or~ · a minimum of · a minimum of · a minimum of neighborhood · a minimum of · a minimum of · a minimum of neighborhood 3 plans 3 elevations per plan 4 different architectural styles per 4 plans 3 elevations per plan 3 different architectural styles per Where the same plan is plotted across from or adja.cent to another, it must be reverse plotted and have a significantly different elevation and color scheme. The use of style-appropriate materials and color schemes helps to achieve greater variety between homes with identical plans and elevations. It is the intent to avoid an overall monotonous color scheme through the use of a varied neighborhood color and materials palette. Varied color schemes shall be applied to homes according to each individual style color palette as shown in the architectural guidelines section of this document. H - 2 Architectural Design Standards Dublb~ Ranch Area F North · June 2003 Setbacks Front yard setbacks shall vary for visual interest. A 2' minimum offset between adjacent buildings is required for lots where minimum rear and front yard setbacks can be met. (Refer to Table I- 1 for specific setback requirements). Treatment of Corner Conditions The treatment of corner lots is key to a successful site plan. All units occupying corner lots shall be designed and placed so that: · The driveway and garage is placed against the interior side yard or accessed from the side street at the rear of the lot. · A clear line of site across the corner is maximized. · The building wall adjacent to the exterior side yard is as short as practical. · The exterior side and front yard setbacks are maximized. Rear Elevations Rows of units seen from a distance or on elevated lots are generally perceived by their contrast against the background. Here the dominant impact is the overall shape of the building and roof lines instead of the surface treatment or materials. In these circumstances: · Maximize the rear yard setback from the top of slope. · Design the rear elevation and roof forms to provide diversity. (Refer to Table I-1 for specific setback requirements). These buildings should appear as varied as practical with particular attention given to avoiding repetitious architectural elements such as fireplace placement, flat rear elevations, and major gable conditions. Each plan shall differ based on rear roof framing so that no rear roofs appear identical in form. There shall be a combination of shed, hip and gables, etc. as seen from adjacent streets. Areas of particular concern include those lots in Area F North Neighborhoods that abut Gleason Drive, Grafton Street and Fallon Road. Refer to Site Development Standards Table I-1 and Massing and Articulation of Side and Rear Elevations, pg. II- 11 for additional specific criteria. [1 - 3 Architectural Design Standards Dublin Ranch Area F North · June 2003 Building Side Yard Separations There are numerous effective techniques for nfitigating the aesthetic and practical aspects of side yard building adjacencies. Side yards in the 10' range are useful in that they optimize density and affordability of a site while minimizing the amount of street paving and length and cost of common utility runs on a site. Various design and plotting techniques can successfully overcome concerns such as privacy, adjacency and accessibility. The Uniform Building Code (UBC) mandates a minimum of 3' clear side yard and/or 6' clear of building separation f~,r non-fire rated single family residences. This is to provide both physical separation to limit the spread of fire and to allow accessibility around structures for fire fighting personnel. Typically, side yards are a minimum of 5' with 10' of building separation to allow for the placement of fireplaces on the side yard and eave overhang of the roof while maintaining the UBC separation criteria. Where setbacks are less than 5', extra attention must be paid to location of such encroachments to comply with UBC and any/all other applicable codes. See Table I-1 for specific setback requirements. The typical aesthetic criticism with the building separations in the 10' range are that they lack privacy where windows align, are too dark and canyon-like when between adjacent two story buildings and the accessibility is reduced because of the placement of storage sheds, air conditioning units and trash storage. Setbacks for encroachments have been established (see "encroachments"), however, local fire authority standards may supersede those stated in this document. Modem planned communities should address these issues through the design guidelines and community standards planning process. Placement of sheds and air conditioners shall be controlled and enforced to insure accessibility. Plan designs shall provide for the placement of air conditioning and trash storage units that do not intrude into either side or rear yard setbacks. Plan designs with attention to the placement of windows must insure privacy. Many of the same techniques used to vary the street scene should also be used to prevent dark canyon- like side yards and rear yards. These include: single story massing elements, hipped roofs, and stepped second stories to minimize side and rear yard depth. H - 4 Architectural Design Standards Dublin Ranch Area F North · June 2003 Encroachments The following encroachments may project up to 2' into yard setbacks: (all non-fire rated encroachments must be at least 3 feet from property lines), eaves, architectural projections, fireplaces, log storage, entertainment niches, balconies, exterior stairs, bay windows, window seats, decks, and air conditioning equipment. Local fire authority standards which may exceed those stated here must be adhered to. SLOPE CONSIDERATIONS Grading Sloped Conditions Where there is adequate space, slope conditions in Area F North should be addressed by creating a series of terraces generally stepping down from north to south. At locations within blocks or at interim points within larger parcels, slope banks or walls shall address any excess slope. The intent is to provide a reasonable number of terraces rather than creating large level areas. Plotting on Cross Slope Conditions When plotting where the elevation difference between lots is greater than 3 feet, the units should be placed so that the driveway is on the high side of the lot. Plotting on Lots at the Bottom of a Slope When plotting and designing the home, maximize the rear yard depth and consider stepping back the rear elevations on the second story to avoid a "canyon-like" rear yard effect. BUILDING MASS AND FORM Residential Massing Exterior mass and form can be manipulated to improve the street scene by reducing the impact of certain home elements as they relate to corner conditions, adjacent units, setbacks and the street. Massing should be designed to decrease perceived density. H - 5 Architectural Design Standards Dublbz Ranch Area F North · June 2003 Architectural Form Building mass should be formulated to reflect interior uses, to create a positive relationship with adjacent homes and land use, to provide visual emphasis and to reflect the architectural style. Methods for maximizing the variety of architectural form within these constraints include: · Creating recessed alcoves or projected overhangs which cast shadows. · Sculpting major chimney forms. · Utilizing dormers, bay windows and other architectural projections. · Using porch/entry projections. Relationship of One and Two Story Buildings A key technique for creating a sense of variety within a neighborhood is to vary the heights and forms of the homes. This can be accomplished by using a combination of one and two story buildings and staggering the massing. It is preferable to use single story elements on fronts and outside edges of comer lots to provide a transition from taller, two story vertical planes to the horizontal planes of sidewalk and street. Introducing an intermediate transition between one and two story buildings helps to improve the visual relationship between the two. Two Story Buildings Style-appropriate, significant single story architectural elements shall be used on two story buildings to lessen their apparent height. (see "Architectural Style Guidelines" of this document for description of style-appropriate elements). Stepping the second story mass, where appropriate to the architectural style, should be used to improve the street scene. The second stones must be set back in relation to the garage face below. Designers shall create the building form as a series of interlocking masses rather than a box. Single Story Architectural Elements A single story architectural element on the front or side provides a transitional step between a two story home and the sidewalk level, helping to create a sense of pedestrian scale. II - 6 Architectural Design Standards Dublin Ranch Area F North · dutle 2003 Significant single story architectural elements include: · A single story room (interior living space) · A front or wraparound porch ( minimum 6' deep and 10' wide) applied when appropriate to the architectural style (See additional porch requirements below) · Extended entry alcove · A single story garage (if located at the side of the home) All architectural elements shall be appropriate to each architectural style as described in the "Architectural Style Guidelines" section of tl~is documcnt. A minimum number of single story homes and/or architectural elements are required in Dublin Ranch neighborhoods according to the following lot sizes and building types. Area F-2 Neighborhood: · At least one plan in the architectural plan package for the neighborhood shall include a significant single story element at the front or side. In Area F-2 neighborhoods where lots are equal to or greater than 5,000 square feet with minimum lot widths of at least 50', all corner homes are required to have a significant single story element that provides added interest and articulation at the front corner. Any portion of the single story architectural element requirements may be satisfied with the use of comer homes. A comer home may be designed specifically for use on comer lots. If not designed specifically for a corner location a home plan must have the flexibility to be easily altered for use on corner or interior lots. Homes located on comer lots require the following: · Front and side fagade articulation using materials that wrap around the side of the home. · A significant single story architectural element (interior space) at the front corner of the plan · Garage placement that allows the option of entry from the side street - (where garage is mid to deep recessed) 1I - 7 Architectural Design Standards Dublin Ranch Area F North · June 2003 Area F-1 Neighborhood: Corner plans for these neighborhoods ~nay be designed for interior lots with the flexibility to be adapted for corner use. Homes located on these comer lots require the following: · Front and side facade articulation using materials that wrap around the side of the home. · A pop out side gable or added single story element (exterior - such as a wrap around porch) Corner tlomes Neighborhood quality is enhanced by the addition of a home plan designed specifically for the corner, or by enhancing an interior plan for use on the comer with additional architectural elements and/or details as typically found on front elevations. The use of the required single story elements is highly encouraged on corner homes. The use of the same plan on every corner however, is prohibited. The intent is to provide a pleasing variety in the street scene using a combination of massing forms and heights. Porch Requirements In addition to comer lots, in neighborhoods where lots are smaller than 5,000 square feet with minimmn lot widths of less than 50', a ~ninimum of I plan per neighborhood (on appropriate styles only) is required to have a porch. Where a porch is included as a single story element, it is desirable for the following design dimensions to be present: · Front porches should be a minimum of 6' depth and 1/2 the width of the front living area facade. · Side porches should be a minimum of 5' depth. · Side porch length should be a minimum of 12' measured from front comer of porch. · Eaves must be a minimum of 12" or 18" deep, as appropriate to style. 11 - 8 Architectural Design Standards Dublin Ranch Area F North · June 2003 See individual Architectural Style Guidelines of this document for guidance regarding style-appropriate elements, colors and materials. Refer to Residential Site Development Standards for Setbacks. Garage Criteria The home and the yard, rather than the garage, should be the primary emphasis of the elevation as seen from the street. In order to achieve this, the following standards are required: · The use of front-facing, 3~car garages is limited to one plan per neighborhood. · Swing-in garages are limited to lots 55' wide or greater. · All homes are required to have both automatic garage door openers and "roll up" doors.* · With the exception of lots along substantial street slopes, plans should be reversed and plotted so that garages and entries are adjacent to each other. This creates an undulating sense of setback. Occasionally this pattern should be broken so that it will not become overly repetitious nor reflected by the units directly across the street. · Locate all garages at least 5' behind the front face/ living space of the home -except swing-in garages. (see "Residential Site Development Standards" for setbacks) · Vary garage placement mix within neighborhood plotting plan · Vary garage door appearance · Vary garage placement from plan to plan * The use of a sectional "roll up" garage door is required since it maximizes the availability of useable driveway length. Residents often tend to misjudge the necessary swing-up distance of conventional garage doors. As a result, they often park with the rear of car extending into the sidewalk path. 1I - 9 Architectural Design Standards Dublin Ranch Area F North · June 2003 The following design techniques are encouraged to reduce the emphasis on the garage: garage placement within neighborhood plotting plan: · Vary garage place~nent where possible by alternating front setbacks along street frontage. · Alternate plans with different garage types when plotting adjacent homes. garage door appearance: · Vary garage door pattern, windows and/or color as appropriate to individual architectural styles. · Where possible, use two single doors instead of a large one. · Additional garage treatments are encouraged to buffer direct view of the garage door. · Stagger the setback between individual adjacent garage doors. F-ary garage placement from plan to plan: · Incorporate the garage with the architecture of the house. The design treatment should strive to reduce the overall visual mass of the garage. · De-emphasize the garage by highlighting other parts of the house with architectural forms. · Where lot depth allows, recess the garage at least 20' behind the primary front facade on one plan. 1. Recessed - (may be detached) 2. Corner with side street entry (may be detached) 3. Swing-in - limited to a maximum of 33% of units in each neighborhood (or 1 plan per package) Recessed Garage All front facing garages shall be located a minimum of 5 feet behind the front elevation/living space. Additional garage treatments are encouraged to further reduce the impact of the garage door. H - 10 Architectural Design Standards Dublin Ranch Area F North · June 2003 Corner with side-street entry Garage This garage placement allows the option of entering from the side street, thereby eliminating the garage and driveway from the front face of the house. Swing-In Garage This garage placement is limited to 33% of homes in single- fanfily detached neighborhoods. Swing-in garages greatly reduce the impact of garage door faces on the streetscape. The resulting l'ront-fatcing ga~ragc wall shall bc articulated with thc same level of detail as the front faqade of the home including windows, trim, etc. Swing-in garages are prohibited on lots less than 55' wide. Swing- in garage doors shall be recessed a minimum of 12" behind the garage wall plane. Detached Garages Detached garages may be deep recessed or located adjacent to the comer with side street entry access. Detached garages are located toward the rear of the lot behind the primary structure. They are enhanced by applying the same details found on the home. Where front-facing, long driveways should be improved by adding texture, pattern or a 'ribbon' driveway. 3-Car Front-Facing Garage Requirements 3-car garages with all doors facing front are limited to: · one plan per neighborhood plan package. · lots that are 5,000 SF or greater · being located at least 5' behind the front fagade of the home (living space) · all other standard garage requirements When a 3-car front-facing garage is used, in addition to standard garage requirements it shall provide at least one of the following additional front-facing plan requirements: 1. Provide and offset a single door at least 2' from a double door. 2. Provide three single garage doors each separated by at least 1' H - 11 Architectural Design Standards Dublin Ranch Area F North · June 2003 Additional garage placements and/or treatments are highly encouraged to reduce the impact of a 3-car front-facing garage on the street scene. These include: · Providing a minimum 6' deep by 10' wide porch forward of all garages. · Constructing the additional car bay in tandem behind the standard 2-car garage door. Optional Garage Treatments The following c)ptional trcatmcnts arc highly cncom'agcd to rcducc or buffer the direct view of all garages and garage doors from the sidewalk or street. Porte Cochere: A recessed garage plan with a port cochere creates an additional, partially covered, parking space and also serves an occasional outdoor private space. Garage Door Screening Elements: · Install elements such as attached trellis' beneath single story garage roof fascias and/or above garage door header trims. · Span the driveway forward of the garage with a gated element or an overhead trellis. ARCHITECTURAL TREATMENT ELEVATION TREATMENT It is the intent of these guidelines to achieve a high quality product that reads well from all sides. The following section provides guidance to help the designer and builder achieve this requirement for "4-sided" architecture. 11- 12 Architectural Design Standards Dublin Ranch Area F North · June 2003 Major Elevations Proper visual balance and sense of cohesiveness creates a successful project design. The differences between the plans and elevations must be readily discernible and create variety, yet at the same time design elements, styles and materials should not contrast to such an extent as to result in visual chaos. All elements, materials and colors shall be appropriate to the architectural style. Siding materials shall be ended inside chimney corners, fence and wall corners, etc. and finished with detail. They shall be brought down to within a reasonable distance from finished grade so that thc skLb is not discernible. Large expanses of blank walls shall be avoided. Elevations shall be designed and articulated consistently with requirements in the Architectural Style Guidelines section of this document. Creation of Form and Relief Recesses and Shadow The manner in which light strikes or frames a building is instrumental in how that structure is perceived. The effect of sunlight is a strong design consideration since shadow and shade gives the building a sense of both depth and substance. Projections, offsets, overhangs and recesses are all tools in the creation of shadow. Architectural Projections Projections not only create shadow but also provide strong visual focal points. This can be used to emphasize some aspect of the design such as an entry or major window. It can also distract the observer's attention away from other elements such as the garage or a large wall plane. Stepping Forms Elevations shall be stepped both horizontally and vertically. Desired changes in material must occur at a step. Entry Statement The entry should be designed to serve as a focal point of the elevation and be readily discernible. The approaching observer should be drawn into it by its visual impact. Buried side-facing entries behind front-on garage plane will not be permitted. H - 13 Architectural Design Standards Dublin Ranch Area F North · June 2003 Massing and Articulation of Side and Rear Elevations Interior Couditions It is not acceptable to "build out" plans to the maximum at side and rear conditions without articulating the mass of those wall planes. This is intended to prevent a two story stucco box, producing a canyon-like effect without vertical or horizontal relief. Required solutions include, but are not limited to, the following: · Create a single story plate at the rear by recessing the second story. · Improve the articulation of the plan forms by offsetting the garage and providing plans that do not utilize the full lot width or depth. · Recess or project the elevation and plan to enhance usable and accessible yard space. Elevations Subject to Public View The rears and sides of homes backing onto streets or open space areas may be highly visible from surrounding areas and shall be treated in a similar manner to the front elevation. This is particularly true of second story conditions visible above the fence line. These elevations are viewed in three ways: first, as seen from adjacent units, second, as semi-public foreground with visible details as seen from adjacent streets, and third, as distant silhouettes viewed from adjacent neighborhoods and public areas. It is required that front elevations and those portions of side and rear elevations of homes that abut a street and are visible from a street shall substantially share common materials and degrees of articulation. Architectural trim, design treatments and materials shall be provided as follows: · Provide detailing of the second floor, to include materials, color, window surrounds and changes in wall planes on first and second floors where appropriate to style. · Trim shall be provided on all windows. · At a minimum, second story windows shall have break-ups (muntins) that match the front elevation windows. · Continue trim and accent materials well beyond the front elevations (see individual style requirements). H - 14 Architectural Design Standards Dublin Ranch Area F North · June 2003 · Homes shall be detailed in an authentic manner. · Address issues of second story privacy and scale in design of building plans and elevations. · For homes backing onto streets provide detailing of the second floor, to include materials, color, window surrounds and changes in wall planes on first and second floors where appropriate to style. · As seen from a distance, ridge lines and framing of homes shall appear varied with particular attention given to avoiding repetitious elements such as continuous gable-ends and similar building silhouettes and ridge heights. · Whcrc possiblc, maximize and vary the rem' ym'd setbacks within rows of lots. · Design the rear elevation and roof plane to minimize negative visual impact. ROOF CONSIDERATIONS Roof Forms Homes seen from a close range or a distance are generally perceived with the contrast against their immediate background or skyline, respectively. Overall building lines are predominant, and appearance is directly impacted by roof massing, not the wall plane ,articulation or materials. The use of different roof types will add variety and interest to the street scene, however the roof characteristics shall always be consistent with whatever architectural style is chosen. To achieve this, roof forms shall be addressed by the following criteria: · Vary the height of ridge lines and fascias in combination with different architectural styles, to create a variety of roof forms and visual interest. · Provide a balance of hip and gable forms that avoid repetitious elements. · Provide a balance of architectural massing and forms that minimize negative visual impact of silhouettes and ridge lines. · Provide plans that maximize their rear yard setback so that building outlines are varied and not as dominant. It - I5 Architectural Design Standards Dublin Ranch Area F North · June 2003 Acceptable Roof Forms There is no single form of roof that is preferred. Hip, gable and sheds may, within reason, be used separately or together on the same roof. Care should be taken to avoid a canyon effect in side and rear yard when both buildings have front to rear gables. Roof forms with pitch changes at a porch or projection are acceptable. Inappropriate Roof Forms Roof forms having dual pitches such as Gambrel or Mansard should not be usc& Flat roofs are not portal;xed. Allowable Roof Pitch The principal roof forms shall have a pitch of between 3 1/2: 12 and 8:12 depending upon dwelling style and character (See Architectural Style Guidelines section of this document). A single roof pitch should be used on opposite sides of a ridge. Shallow pitches tend to lessen the apparent building mass. Design of Rakes and Eaves The designer may choose from a variety of rake and eave types based on climatic and stylistic considerations. Moderate or extended overhangs are acceptable if properly designed. Tight fascias with appropriate styles are acceptable. Single fascia boards, double fascia boards, or exposed rafters when adequately scaled are acceptable. Care should be taken to ensure ~naterial sizes avoid a weak or flimsy appearance. Exposed rafter tails without fascias should be at least 3x. Overhang Projections and Covered Porches Substantial overhangs are encouraged as a response to solar and climatic conditions. The inclusion of covered porches and entries expand sheltered living spaces, create entry statements and provide elevation relief. Covered porches may differ from the roof in both pitch and material but front porches should retain at least one of these two characteristics. [1 - 16 Architectural Design Standards Dublin Ranch Area F North · June 2003 Stepping the Roof Form Steps in the roof respond to the interior room arrangement and provide visual relief and interest. A vertical step within the ridge line should be at least 18" in order to create visual impact and allow for adequate weatherproofing. ARCHITECTURAL DESIGN ELEMENTS The following sections provide guidance concerning specific clcmcnts of residences ~uch as entries, doors, windows and garages. Unit Entries Use of Entry Statements The entry serves several important architectural and psychological functions: · Identifies and frames the front doorway. · Acts as an interface between public and private spaces. · Acts as an introduction to the house while creating an initial impression. Placement and Visibility The entry should be designed and located so as to readily emphasize its prime functions. If the front door locations is not obvious or visible because of building configuration, the entry should direct and draw the observer in the desired path. The design of the entry in merchant built housing shall be strong enough to mitigate the impact of the garage on the facade. Incorporation of Roof and Architectural Features Proper use of roof elements, columns, feature windows and architectural forms contribute to the overall impact and success of the entry. A covered entry is a traditional American housing element. It may no longer serve as a living activity area (i.e., porch or veranda) but still has an important function as a semi-private transition between the public walkway and the private interior. Even when the entry visually obscures the door, it still announces the door. I1- 17 Architectural Design Standards Dublin Ranch Area F North · June 2003 Doors Design Emphasis should be placed on the design and type of entry door used. It functions as the major introduction to the interior of the house and concern should be given to the image it creates. · The entire door assembly should be treated as a single design element including surrounding frame, molding and glass side lights, if present. · Typically, the door should be covered by an overhead element or recessed into the wall plane. Materials/Colors Traditionally, wood is used for the entry door. Wood grain texture and raised or recessed panels contribute to the appeal of the door. Greater use is being made of metal entry doors but in order to be acceptable, they must possess the same residential "feel" provided by the wood grain and panels. Flexibility is allowed concerning the color of the door. It may match or contrast the accent trim, but should be differentiated from the wall color. Use of Glass The use of glass in the door and overall assembly is encouraged. It expresses a sense of welcome and human scale. It can be incorporated into the door panels or expressed as single side lights, double side lights, transom glass or fan windows. Residential Address Numbers and Entry Lighting All residential addresses shall be clearly marked, located and sufficiently lit for ease of recognition by postal and public safety agencies. H - 18 Architectural Design Standards Dublin Ranch Area F North · June 2003 Windows Placement and Organization Typically, the location of windows is determined by the practical consideration of room layout, possible furniture placement, view opportunities and concern for privacy. Greater design emphasis shall be directed to insure that window placement and organization will also positively contribute to the exterior architectural character. Windows greatly enhance the elevation through their vertical or horizontal grouping and coordination with other design clements. This relationship to one another and the wall/roof plane creates a co~nposition and sense of order. All windows in a specific plan elevation shall appear compatible. This should not be interpreted that they are all the same shape, size or type but rather that a hierarchy of windows exists which visually relate to and compliment one another. Feature/Theme Windows Feature or theme windows on the front elevation create a strong visual focal point. These focal points may be used to decrease the visual impact of the garage door, draw attention to the entry or emphasize some other element of building. Within the window hierarchy, this window creates the dominant theme or form. Window Frames Vinyl clad, aluminum, wood or cementitious simulated wood window frames are acceptable. When using aluminum, bronze anodized frames or those complementary to the color palette shall be used while natural, silver or gold anodized frames are unacceptable. All windows must be articulated and/or trimmed appropriately to individual style as described in the architectural style section of these guidelines. Use of Wood and Stucco Trim When aluminum tYame windows are used, they shall be surrounded or trimmed with other design elements. These may include wood or cementitious simulated wood trim, stucco surrounds and shutters or recessed openings as appropriate to the architectural style. H- 19 Architectural Design Standards Dublin Ranch Area F North · June 2003 Considerations of Rear Elevations Merchant built housing typically fails to adequately address proper window design and placement on rear and side elevations. This is usually due to prioritization and cost factors. Since side elevations and second story rear windows are frequently visible, greater design effort and budget prioritization need to be given. The guidance concerning window placement organization, trim and incorporation of architectural elements is applicable to all elevations and will be enforced through the design review process. Integrations with Roof and Architectural Details The window is important to the proper articulation of the wall and roof elements. Focal points can be created by the placement of windows in architectural projection or recesses incorporated with gable, hip or shed roof overhangs. Consideration should be given to using overhangs and projections to shadow windows with south and west exposures. Skylights Skylights and roof windows are permitted where they are not visible from any street, if properly installed and weather proofed. The skylight should be designed to appear as an integral part of the roof plane. Skylights should be clear or bronzed with the framework matching the roof or trim color. Balconies The inclusion of balconies is encouraged for both aesthetic and practical purposes. They are useful in breaking up large wall planes, offsetting floors, creating visual interest and adding human scale to the building. They provide the practical advantage of creating outdoor living areas and elevated open space. Balconies may be covered or open. They may be either recessed into the mass of the building or serve as a projecting element. In whichever manner they are used, they must appear to be an integral element of the building rather than an after thought or add-on, the details, eaves supports, and railing must be consistent with the balance of the building design elements or style. Concern should be given to avoid designing balconies in plans in such a manner that they are plotted side by side. I1- 20 Architectural Design Standards Dublin Ranch Area F North · June 2003 Exterior Stairs Stairs should be compatible in type and material to the deck and landing. Use of open stair treads can only be justified where the balcony or landing element is a projecting element. Location of exterior stairs is permitted on the side or rear of the home except on facades that side or back onto public streets or open space areas. Columns and Posts It is important that both columns and posts project a substantial and durable image. Posts should be of wood, not less than 6" in diameter, and may be built up from multiple pieces. Use of 4" posts and metal pipe columns is prohibited. Columns may be clad in wood, masonry or stucco. They should be square, rectangular, or round and at least 14" wide with a height of approximately 4 to 5 times the width. It is desirable that columns incorporate both base and capitals. Related arches may be flat, round or segments of an inch. Other variations such as parabolic curves are unacceptable. Railing The type of exterior railing used on balconies, decks and stairs, creates a significant impact on the elevation. An extensive variety of rail types are permitted including open wrought iron and wood rail or picket. Extruded aluminum is prohibited. Choice of rail type should reflect taste and be consistent with the chosen design vocabulary or be historically correct for the style. Gutters and Downspouts Exposed gutters shall be colored to match fascia material. Exposed downspouts will likewise be colored to match the surface to which they are attached unless they are finished with a false copper patina. II- 21 Architectural Design Standards Dublin Ranch Area F North · June 2003 Chimneys Properly designed and located chimneys can serve as a major design element and focal point for the building elevation. It is frequently the major architectural element on exposed side or a rear elevation. Chimneys should be constructed of style- appropriate materials as described in the architectural styles section of this document. Care must be taken concerning the selection of any accent materials and the cap design. The use of steps, curve and banding on the shaft and capital have major visual impact against the sky and roof plane. Attention should be given to the Git3' setback requirements. Garages and Garage Doors Materials "Roll up" garage doors shall be used on all single-family homes. Metal, wood or fiberglass garage doors are permitted when they include either textured or raised panels of a "residential" nature. The use of window elements is encouraged. The design of garage doors should reflect the theme or style of the overall design of the residence. Proper use of accent colors will compliment the architecture and provide visual variety along the street scene. Refer to the individual color palette for each style. Face Design The design of the door face should result in a tasteful treatment which breaks up the expanse of the door plane while not being so excessively decorative as to draw attention away from the architectural elevation. Recessing It is highly desirable to recess the garage door 6"-12" from the garage face. This allows for a strong shadow line and decreases the impact of the door while increasing the apparent sense of mass of the surrounding wall. H - 22 Architectural Design Standards Dublin Ranch Area F North · June 2003 Patio Covers Patio covers, trellises, pergolas and other exterior structures should reflect the character, color and materials of the building to which they are related. Supports and framing members will conform to the guideline criteria for columns and posts. The pitch of the patio roof may be less than the adjacent building. The materials for the horizontal elements are limited to either wood or the dwelling's roof material. The side elevation of the structure will not be enclosed except in the case where a wall of the dwelling forms a natural enclosure. Ensure that building plans allow space for the later addition of usable patio covers within the buildable envelope and setbacks. Storage Structures If storage structures are used, they must be designed and constructed in accordance with the criteria for the residence as stated in the Architectural Style Guidelines of this document. Prefabricated metal or vinyl sheds are prohibited. All such structures must be screened from view where adjacent to public streets or open space areas. Further Design Considerations All mechanical or other equipment, including utility meters, junction boxes, trash receptacles and air conditioners should be screened from public view. Further consideration should be given as to the placement of these items within the side yards so as not to restrict pedestrian access in emergency situations. They may be accommodated within the rear yard with minimal impact on yard use and layout. All antennas shall be placed in attics or interior of the residence. Inclusion of exterior compact satellite dishes is limited to locations that are not visible from the street or side yards from adjacent lots wherever possible. Canvas awnings of solid accent color may be permitted with moderation. Refer to individual style color palettes for criteria. Metal awnings are prohibited. The decision whether to provide awnings should include consideration of their maintenance and deterioration in neighborhoods without maintenance associations. II - 23 Architectural Design Standards Dublin Ranch Area F North · June 2003 ATTACHMENT A: ARCHITECTURAL STYLE GUIDELINES PURPOSE The goal of these architectural guidelines is to provide more specific design guidance for the residential architectural styles to be used in Neighborhoods F-1 and F-2 in Dublin Ranch. They have been developed to establish a high level of architectural quality, to assure both variety and compatibility and to enhance the community's overall value. The goal for Dublin Ranch neighborhoods is to promote both visual harmony and variety in a community setting achieved by utilizing a number of compatible traditional and contemporary styles and through architectural innovation. Builders will select from the architectural palette described herein to create their own combinations of neighborhood styles, plans and colors. Each neighborhood will eventually develop a unique character within the overall image of the community. Dublin Ranch will remain unified through the implementation of an overall plan tbr landscaping, signs and entry monumentation. RESIDENTIAL ARCHITECTURAL STYLES Dublin Ranch represents an opportunity to develop a unique community combining the most positive aspects of a master planned development with the most favorable building types and styles of long established neighborhoods. These guidelines are based on the prior learning curves of earlier planned communities and can thus implement the successes achieved while avoiding the negative aspects sometimes created. I1 A - I Architectural Style Guidelines Dublin Ranch Area F North · June 2003 Key to a successful project is the development of an appropriate architectural vocabulary and theme which avoids two alternative pitfalls found in some residential developments. One of these is the selection of a single "trendy" style which when used everywhere is monotonous, repetitious and, as a result, quickly becomes dated. The other extreme to be avoided is the combination of strongly contradictory styles and incompatible designs which lead to visual chaos. To achieve a successful middle ground, it is the intent for Dublin Ranch to become a quality living enviromnent with an identifiable visual character that establishes itself at the community entry and community facilities, is maintained along the major roadways, and carries through to the neighborhood entries and individual homes. The goal is to provide both variety and compatibility while creating a sense of familiarity. The styles selected convey a sense of classic character and an opportunity to develop a high quality neighborhood environment. For concept and inspiration, we have turned to the greater Dublin area's own architectural past. In small towns of both the East Bay and the Central Valley, one finds attractive established neighborhoods composed of homes built during the opening decades of the past century. These neighborhoods consist of a mixture of interesting and different, yet compatible styles. From among these "period" or eclectic styles, we have selected those which are not only attractive and compatible but can also be reasonably integrated into a modern merchant-built home. These styles are: · California Craftsman/Bungalow · American Colonial · European Eclectic · Monterey · California Ranch · American Farmhouse · East Coast Traditional These closely associated architectural styles have each evolved in California since the turn of the 20th century and examples are well represented in the East Bay and Central Valley area. Their inherent attractiveness, informality and sense of elegance have enabled these styles to remain popular over a long period of time. II A - 2 Architectural Style Guidelines Dublin Ranch Area F North · June 2003 All styles shown here possess characteristics that the designer and builder shall consider when choosing a desired style or image. Specifically, the styles: · Are visually compatible with each other. · Possess general market appeal and community acceptance. · Can be successfully expressed in a modern merchant built home. · Are capable of authentic interpretation and variation. · Have a historic background and precedence in the East Bay and Central Valley area. The following sections will address each style, defining those elements that are characteristic. The text and graphics are intended to provide specific direction, guidance and authentic inspiration to the builders and architects as they design today's interpretations of these historic styles. It is not the intent of these guidelines to permit any false front architectural design. All sides of the building shall be articulated and consistent with the specific style selected for the residence.

Of the utmost importance was that all exterior and interior elements received both tasteful and "artful" attention. The movement influenced numerous California architects such as Green and Green, and Bernard Maybeck. The resulting Craftsman style responded with extensive built-in elements and by treating details such as windows or ceilings as if they were furniture. The overall affect was the creation of a natural, warm and livable home. The style is further characterized by the rustic texture of the building materials, broad overhangs with exposed rafter tails at the eaves and trellises over the porches. The Craftsman style evolved in California, inspired by bungalows that were the production home of the time. This type of architecture can be found in classic tree lined neighborhoods throughout California. This unique look promoted hand crafted quality; thus the name Craftsman.

Their beginnings were as small and unpretentious as the one story saltbox, favoring the cultures and traditions of the settlements. As living functions became more defined and prosperity increased, so did the need for additional space. Second stories with overhangs, dormers and gabled roof forms became favored solutions, evolving into classic elements of this traditional American style. Later, wings of smaller continuous gable forms were added to each side of the house, becoming a lasting characteristic. Wood shutters and white picket fences became the finishing details for an otherwise simple and functional form. With the influence of Greek Revival styles in the 19th century, the American Colonial style evolved into a more decorative form known as Colonial Revival. Borrowing classic elements from Greek styles, the simple Colonial central front donner window evolved into a standard, prominent roof element or decorative pediment entry form; a portico. The portico was supported by massive classic columns, raising the level of drama and sophistication of this style.

EUROPEAN ECLECTIC Historical Precedent The European Cottage is a style that evolved out of medieval Tudor and Norman architecture. This evolving character that eventually resulted in the English and French "Cottage" became extremely popular when the addition of stone and brick veneer details were developed in the 1920's. Although the cottage is looked upon as small and unpretentious, the style was quickly recognized as one of the most popular in America. Designs for the homes typically reflected the rural setting that they evolved in. Many established older neighborhoods across the United States contain homes with the charm and character of this unpretentious style. Roof pitches for these homes are steeper than traditional homes, and are comprised of gables, hips and half-hip roof forms. The primary material is stucco with heavy use of stone and brick bases, veneers and entry elements. Some of the most recognizable features for this style are the stucco accents in gable end forms and the sculptured swooping walls at the front elevation.

Prior to this innovation in Monterey, all Spanish colonial houses were of single story construction. First built by Thomas Larkin in 1835, this style introduced two story residential construction and shingle roofs to California. This Monterey style and its single story counterpart eventually had a major influence on the development of modern architecture in the 1930's. The style was popularized by the use of simple building forms. Roofs featured gables or hips with broad overhangs, often with exposed rafter tails. Shutters, balconies, verandas and porches are integral to the Monterey character. Traditionally, the first and second stories had distinctly different cladding materials; respectively siding above with stucco and / or brick veneer base below.

The Ranch house was the primary focus of the enormous ranches developed by the early Californians. Representing one of California's true vernacular styles, the Ranch house evolved naturally from native materials and considerations of climate and lifestyle. The primary building materials were adobe, tile roofs and wood detailing. In the later years of its evolution, the Ranch house was adapted to also include shingles for roofs, board and batten siding and other colonial features introduced in Monterey. Plans were typically organized around a courtyard, which became one of the primary living spaces. The houses were generally simple and straight forward while using thick adobe walls, gabled roofs and an occasional hipped roof. In the mid-1930's Cliff May, a designer, began adapting the ranch house design and layout to the needs of family living. His design considerations maintained much of the authentic character of the early "ranchos", but started using contemporary materials. It initiated the current acceptance of the informal open room plan and the strong relationship between indoor and outdoor living. 1I A - 20 Architectural Style Guidelir~es Dublin Ranch Area F North · June 2003 CALIFORNIA RANCH STYLE (Cont.)

Its beginnings are traced to both Colonial and Cape Cod styles begun in New England. As the American Frontier moved westward, the American Farmhouse style evolved according to availability of materials and technological advancements, such as balloon framing. Predominant features of the style are large wrapping front porches with a variety of wood columns and railings. Two story massing, dormers and symmetrical elevations occur most often on the New England Farmhouse variations. The asymmetrical, casual cottage look, with a more decorated appearance, is typical of the Midwest American Farmhouse. Roof ornamentation is a characteristic detail consisting of cupolas, weather vanes and dovecotes. Design Characteristics The design characteristics provide the essentials for massing, scale, proportion, building materials, and details in understanding the primary concepts for this style.

H A - 26 Architectural Style Guidelines Dublin Ranch Area F North · June 2003 WOOD SIDING-- MANUFACTURED FLAT TILE - SIMULATED SHUTTERS -- --- SHINGLE OR SHAKE .~' , AND DETAIL TRIM, EAST COAST TRADITIONAL Historical Precedent The East Coast Traditional style evolved in the early twentieth century being influenced by American Colonial styles as formal as Georgian Revival and those as simple and functional as Cape Cod, New England Colonial and Farmhouse. With respect to East Coast traditions and regional culture, the Colonial Revival vocabulary of white-painted columns, clapboards and shuttered windows were combined with the less symmetrical, unpretentious massing and functional forms of the Cape Cod and farmhouse. Combined one and two story massing with single story wings, gabled roofs with dormered windows, or occasional saltbox roof forms were favored solutions, later becoming classic forms of the traditional style. These inspirations yielded a truly American inspired architecture for a more relaxed, yet still dignified style that would become the new American dream. The characteristic elements and details of this style further demonstrate the blend of American Colonial influences. Use of brick and/or wood siding with somewhat formal character elements and generous trim above the doors and windows is typical. Some of these character details include donnered windows, wood shutters, rounded or squared columns at porch or entry statement and decorative broken pediment trim and painted wood vents in gables.

VEHICULAR CIRCULATION A hierarchy of streets comprise the vehicular circulation system within and through Dublin Ranch. The goal has been to create' synergy and maintain a particular scale, community character, and provide a series of logical connections. Pedestrian walks, bicycle lanes, and multi-use trails adjacent to streets will provide a favorable atmosphere for recreational pursuits and efficient connections throughout the community, in addition to alternative types of commuter transportation. Infrastructure design consistency is executed through a well- established vocabulary of site furnishings, streetlights, signage and plant material articulating arterial, collector, and local residential rights-of-way. These elements provide the consistent visual image that unifies the community theme and character established with Phase I of Dublin Ranch. Arterial Streets - Gleason Drive and Fallon Road Arterial streets define edges of specific planning areas within Dublin Ranch. Both Gleason Drive and Fallon Road provide opportunities for several levels and choices of travel such as vehicular, public transit, bicycles, and walking. Walkways shall be separated from the street to provide for a safer pedestrian environment. Planting shall be designed to define the arterial street from adjacent land uses and provide an interesting view corridor for both the motorist and pedestrian. Street Design Concept Gleason Drive will consist of four traffic lanes, a landscaped median, and bicycle/emergency lanes on both sides of the street. Fallon Road will consist of four traffic lanes, a landscaped median, and bicycle/emergency lanes on both sides of the street. Each side of the street will ultimately include a separated sidewalk within a landscaped area. An additional public service and landscape easement extends beyond the right-of-way line on both sides of the street. A public service easement (PSE) will be provided as required by the City and will be dedicated to the public as shown on the Tentative Map. Parcels will be created for landscape buffer areas and will be owned and maintained by the Homeowners Association.

Page 111-8 Landscape Architectural Design Guidelines Dublin Ranch Area F North · December 2003 Landscape Treatments Gleason Drive medians and parkways will be predominantly planted with evergreen street trees. Flowering trees will be used as accents in key locations. Drifts of tiered (or layered) shrubs and low growing groundcover shall be repeated in elongated patterns over large areas for viewing at higher travel speeds. This will provide a buffer adjacent to residential development as well as providing an attractive environment for motorists, pedestrians, and bicyclists. Where appropriate, groundcover will be placed within the parkway and beyond the sidewalk Fallon Road is designed to be more rural in character and shall utilize similar plant material as Gleason Drive with the inclusion of riparian species. The density of the planting shall be reduced to transition to the intermittent stream corridor landscape. Pilasters, Walls, and Fences The wall/view fence shall be placed adjacent to residential lots that side/back to Gleason Drive, with stone pilasters placed at each property line. Where sound attenuation is required, the community wall and stone pilasters will be placed adjacent to residential lots. The incorporation of the community wall and stone pilasters as accents for the neighborhood entry shall provide visual interest and continuity while reflecting the character of the community. Where a street runs adjacent to Gleason Drive a three rail concrete fence shall be located adjacent to sidewalk Collector Street- Graflon Street/Kohnen Way/Brannigan Street To create a more pedestrian friendly environment and sense of community, the collector street shall have and expanded fight-of- way greater than the City of Dublin standards. This increased width will allow for a landscape parkway and separated multi-use trail or sidewalk along each side of the roadway. A row of shade trees will be planted on either side of the sidewalk, one within the parkway and one within the landscape easement beyond the right-of-way. This will allow the pedestrian path-of-travel to act as a safe domain by visually and physically minimizing the interaction of the pedestrian and motorist while creating a more pedestrian-oriented neighborhood corridor. Grafton Street from Gleason Drive to the property line consists of two traffic lanes, two parking lanes and a landscaped median/turn lane. A parkway strip with a separated multi-use train (one-way pedestrian/bicycle travel on the east side and two-way pedestrian bicycle travel on the west side) will be provided. A public service easement (PSE) will be provided as required by the City and will be Page 111-9 Landscape Architectural Design Guidelines Dablin Ranch Area F North · December 2003 dedicated to the public as shown on the Tentative Map. Parcels will be created for landscape buffer areas and will be owned and maintained by the Homeowners Association. On the west side, beyond the right-of-way line, is the stream/open space corridor. The portion of Kohnen Way south of the proposed middle school site and the extension of Brannigan Street between Gleason Drive and Kohnen Way are designed as residential collector streets. Kohnen Way typically consists of two travel lanes and two parking lanes. A parkway strip with separated multi-use trail (two-way pedestrian/bicycle travel) will be provided on the south side and an integral curb/sidewalk on the north side. The portion of Kohnen Way from the Grafton Street intersection to the middle school entry driveway will be widened to accommodate a landscape median. On the portion of Kohnen Way between the entry and exit from the Middle School drop-off and parking, there will be a Bus pull-out and parking will be prohibited on the school side of the street. (See SDR drawings for details.) The extension of Brannigan Street will consist of two travel lanes, two parking lanes and a landscaped median/turning lane extending from Gleason Drive intersection northerly to the first intersection into the F1 neighborhood. A parkway strip with separated multi-use trail (for two-way pedestrian/bicycle travel on the east side) or sidewalk (on west side) will be provided. Parcels adjacent to the right-of-way will be created for landscape buffer areas in selected locations and will be owned and maintained by the Homeowner's Association. Landscape Treattnent The dominant feature of the residential collector shall be deciduous shade trees to create a canopy effect for pedestrians and motorists. Only one species of tree shall be allowed to clearly and consistently define this collector. Shrubs and groundcover shall be planted where a community wall or rail fence runs parallel to the multi-use trail. Flowering deciduous vines shall be planted adjacent to the community wall. Planting along the rail fence should be predominantly indigenous species when transitioning into the open spaces or intermittent stream corridors. Lawn shall be planted within the parkway strip Pilasters, Walls and Fences The community wall or wall/view fence shall be placed along the rear lot lines of residential lots that back and side onto Grafton Street or portions of Kohnen Way. Where sound attenuation is required, the community wall and stone pilasters will be placed adjacent to the Page IH- 10 Landscape Architectural Design Guidelines Dublin Ranch Area F North · December 2003 residential lots. The incorporation of the community wall and stone pilasters as accents for the secondary neighborhood entries shall provide visual interest and continuity while reflecting the character of the community. To maintain vistas, a rail fence shall be placed 5' behind the walk when adjacent to open space or intermittent stream con-idors. Stone pilasters shall be incorporated into the wall/view fence at property comers and rail fence junction points to provide design continuity throughout the community and shall conform to the typical elevations in the guidelines. Residential Streets Residential streets are pedestrian oriented and accommodate a lighter volume of traffic. They have a strong influence on the character of the neighborhood. Street trees shall act as the primary landscape element affording each neighborhood individualized personality, beauty, and seasonal character. Landscape Treatment Each neighborhood shall create its own identity through the use of one species of street tree per neighborhood. Through the use of a single species per neighborhood, a grove effect will be created. Where practical, each lot shall be required to have a minimum of one street tree and comer lots shall require two. Street trees are to be planted 5' behind the sidewalk (on private property) within the PUE/landscape easement. Pilasters, Walls and Fences Fences placed at property lines, returns to homes, and the side yard of all comer lots shall be wood good neighbor fences. Where fences are visible from any residential street the good neighbor fence shall have an open lattice top conforming to the typical details in these guidelines. A two-rail fence shall be placed three feet (3') behind the back edge of the sidewalk where residential streets are adjacent to open space and the future middle school site. Cul-de-sac Connections Residential streets terminating in cul-de-sacs shall be designed to provide visual and pedestrian access to arterial or collector streets and open space wherever possible. To define pedestrian access from residential lots a two or three rail fence shall be tied into the side yard fencing. The two- rail fence shall be used in all locations with the exception of cul-de-sacs that open onto arterial streets, where a three-rail fence shall be placed. Page III-I 1 Landscape Architectural Design Guidelines Dublin Ranch Area F North · December 2003 Traffic Calming Islands in F2 Neighborhood Traffic calming islands have been placed at two locations within the F2 Neighborhood. To accentuate these traffic calming devices, a specimen tree shall be placed in each island along with colorful groundcover. STREET FURNITURE Street furniture should reflect the community theme and architectural styling of this "upscale rural" community. Benches and other pedestrian amenities should be placed at the mid-block pedestrian access. Additional street furniture such as bollards, mailboxes, and street lights shall be placed according to function to provide a cohesive design. Refer to Materials Source List, page III- 33 for specifications of product types to be used. Bollards Bollards shall be identical to those used in Phase I of Dublin Ranch. They should be placed in locations where pedestrian walks and vehicular traffic meet. Benches Benches shall be shall be identical to those used at the community entries of Dublin Ranch Phase I. Trash Receptacles Trash receptacles shall complement the benches and shall be identical to those used throughout Dublin Ranch Phase I. They should be placed in convenient and accessible locations from pedestrian walks. Mailboxes Mailboxes shall meet the U.S. Postal Service standards. When a mailbox serves only one or two homes, it shall be paired on either side of a post with boxes designed to reflect the character of Dublin Ranch. Street Light Standards Street lighting plays a crucial role in enhancing the level of quality and character of Dublin Ranch. Light standards shall be uniform in color and style. Lights on the arterial streets shall conform to the City of Dublin's standard cobra head and shall be painted to match Page III- 12 Landscape Architectural Design Guidelines Dablin Ranch Area F North · December 2003 the decorative lights to be used along collector and local residential streets. Street lights on collector streets and in residential areas will be the same decorative fixture design and height approved for Phase I to reflect the character of the Dublin Ranch community. All lighting shall be designed to conform to City of Dublin, Pacific Gas and Electric and IES safety standards and illumination requirements. With the exception of the arterial streets, all other streets shall utilize a metal halide light source in conformance with the approved light source for Phase I of Dublin Ranch. Street Identification Signage Street signs shall be round galvanized steel poles painted to match the decorative street light standards. Graphics on signs will display the City of Dublin logo and the name of the street. OPEN SPACE & PEDESTRIAN CIRCULATION The community's open space system shall provide a network of interconnected multi-use trails, bicycle route bike lanes, and a mid- block pedestrian access linking neighborhoods to the community. Stream/Open Space Corridors The stream/open space corridors function as linear circulation routes along the westerly side of Grafton Street between the northern property line and Gleason Drive and along a of portion of Fallon Road north of Gleason Drive. These corridors have been designed as wildlife habitats and will be a continuation of the stream/open space corridors winding through Dublin Ranch Phase I. A 12' wide multi-use trail (for two-way pedestrian/bicycle travel) will be located on the eastern stream bank. It will meander where physically feasible, providing a pedestrian and bicycle connection to proposed parks, schools, neighborhoods, village center, and other areas of Dublin Ranch. At trail access points, bollards will be placed across the opening to prevent unauthorized motorized access. Appropriate directional and informational signage will be provided (in accordance with the American with Disabilities Act 1990). Design Criteria Construction of the stream/open space corridors will provide a naturalized channel with a gentle curvilinear alignment where feasible. If weirs are needed to stabilize the channel, natural materials such as boulders or logs will be utilized. Page 111-13 Landscape Architectural Design Gaidelines Dubliu Ranch Area F North · December 2003 California native, indigenous and appropriate trees, shrubs, and ground covers will be planted within the stream/open space corridor based on species, water requirements, user safety and security surveillance visibility. Channel shading is a critical factor for the development of wildlife corridors. When feasible, vegetation will be installed in masses overhanging the stream. Concentrated plantings within 8' of the streambed will provide the most shading. Barriers, such as solid fences, that may impede the movement of wildlife within the stream/open space corridor will not be permitted. During and after construction of adjacent lands, site-specific storm drains and erosion control practices will be employed to limit sedimentation of the intermittent stream/open space corridor. Human access within the stream/open space corridor will be controlled via fencing, trail placement, and interpretive signage. Where possible, the multi-use trail should be set back as far from the channel as possible to maintain habitat quality. New homeowners will be apprised by written documentation, in addition to signage, of the enforcement of pet leash laws within the stream/open space corridors. Multi-Use Trail The multi-use trail will serve as a shared bicycle and pedestrian trail linking residential areas to community-wide parks and open spaces and to other local and regional trail systems. Dimensions Multi-use trails shall be twelve feet (12') wide with the exception of the trail on the east side of Grafton Street which shall be eight (8') wide. Removable bollards shall be placed at all entry points to prevent unauthorized motorized access. Materials Multi-use trails shall be paved with concrete. Striping shall meet City standards. Signage Appropriate directional and informational signage, as determined by the City of Dublin, will be provided. Page III-14 Landscape Architectural Design Guidelines Dablin Ranch Area F North · December 2003 Bicycle Route Bike Lane The bicycle route bike lane, occurring within arterial streets, will serve to link residential areas to community-wide open spaces and parks, and other local and regional trail systems. Dimensions Bike lanes shall be a minimum of 5' wide. Materials Striping shall meet City standards. Signage Appropriate directional and informational signage shall be provided. Pedestrian Access Pathways Pedestrian pathways represent the interior pedestrian circulation route linking neighborhoods to surrounding streets. Pedestrian pathways are included in both neighborhoods and shall be accented with low stone walls and/or rail fences to draw the pedestrian into the pathway. Where feasible, pedestrian paths should be accessible to all. Dimensions The width of the pedestrian pathway shall be 8'. Removable bollards shall be placed at all entry points at the arterial and residential streets to prevent unauthorized motorized access.

Ownership and Maintenance The stream/open space corridors adjacent to Fallon Road and Grafton Street shall be owned by the Homeowners' Association. The City of Dublin will maintain the multi-use trail system within the stream/open space corridor while the Homeowners Association will maintain the stream channel and all landscaping within the corridor. The Homeowners Association will provide an easement to the City of Dublin for access to the multi-use trails. An existing 30' wide landscape maintenance easement, which is adjacent to the Dublin Ranch Phase I M3 Neighborhood (Tract 6964) will remain. While the easement is located within the future Public/Semi- Public parcel located west of the F-! Neighborhood, the land within the easement will continue to be maintained by the Phase I Homeowners Association. Management and maintenance includes drainage systems, pedestrian pathway, landscape maintenance and vegetation monitoring. GENERAL LANDSCAPE The beauty of the existing rolling topography and natural landscape is the basis for the Dublin Ranch landscape concept and planting themes. Rows of trees delineating entries and streets shall depict the historical aspect of orchards and create a sense of community. Indigenous and horticulturally adaptive plant materials shall serve as unifying elements throughout Dublin Ranch. Trees shall be used to define a hierarchy of entries, streets, and neighborhoods providing individuality and distinctiveness. Oak trees, native to the Tassajara Hills, have been incorporated into the plant palette to reflect the historical landscape of the Th-Valley area. Recommended Plant Palette Following are recommended plant palettes which establish the desired character of Dublin Ranch. Plants have been selected to enhance entries and streets, provide shade where necessary and transition areas to open spaces/intermittent stream corridors. Special attention has been paid to the selection of indigenous and ornamental plants that are horticulturally adaptive to the natural characteristics of the site and are suited to the climate, soils, and recycled irrigation water.
