    2METROPOLITAN PARK

    Purpose and Intent

    The Metropolitan Park Design Guidelines have been derived from

    design principles that were identified and discussed in a companionProject Book dated November 12, 2003. The guidelines in this book

    detail the pattern of development for this future residential community,and establish standards for streets, buildings, open space, andlandscaping as a means of insuring quality and consistency as phaseddevelopment proceeds over time.

    This Design Guidelines document and its companion Project Bookrepresent the evolution of Pentagon City planning and development and

    set the stage for the completion of the residential component of thePentagon City Plan.

    Sufficient detail is provided in the Design Guidelines document for the

    community and residents to know the quality of development which isexpected, but not so rigid as to stifle design and innovation for the

    future.

    The Design Guidelines insure a level of quality which can be easily

    referenced for future buildings.

    This Design Guidelines document is to be adopted by reference into theCounty Board approval of the Planned Development Site Plan (PDSP)for Pentagon City.

    Building heights shall vary throughout thedevelopment generally tapering up from

    lower density residential development.The number of stories portrayed on theFramework Plan reflect locating all of theapproved residential units between 12th

    Street and 15th Street. The actual numberof stories may vary slightly with theapproval of the 4.1 site plans. Maximumheights are indicated in each phase ofdevelopment.

    STREET CLASSIFICATION

    Primary streets are located around theperimeter of the development. They

    connect the proposed development withthe surrounding Pentagon Center area.12th Street shall be extended betweenSouth Fern and South Eads Streets. All

    primary streets shall be public streets.

    Secondary streets shall form a modified

    street grid pattern within the developmentbetween South Fern and South EadsStreets, and between 15th and 12th Streets.The north/south road shall be broken by

    the central park feature both to promotetraffic calming and to maximize openspace. All secondary streets shall beprivate with public access easements

    placed in them.

    Tertiary streets shall provide internal

    access for individual phases of thedevelopment. All tertiary streets shall beprivate with public access easements

    placed over them and where appropriate,the streetscape may incorporate unique

    design elements such as specialty paving,awnings and landscaping to create settingsfor particular buildings.

    Street names, as shown are i llustratives.Final names will be approved by ArlingtonCounty.

    Streets shall be classified as primary, secondary,

    A Central Green shall be designed as acontinuously accessible ground plane made upof large and small open space components witha prominent north/south pedestrian connectionthat helps to organize the open space. Asresidential build-out occurs and community

    needs are assessed, this portion of the park maybe programmed for a variety of active andpassive recreation. Large and small open spaceareas shall therefore be sized to accommodate

    outdoor community gatherings, more active usessuch as frisby toss and impromptu ball games

    with friends and family, recreation alternatives forsmall children, and passive uses such as sitting,strolling, and reading. A tot lot shall beincorporated into the open space plan.

    Smaller parks to the north, south and east of the

    central green shall be designed as integral partsof the residential components with which they areassociated while at the same time providing an

    extension both visually and physically to theCentral Green.

    Open space within the core of the project shall compriseapproximately 2 acres, be open to the public and be

    designed to accommodate a variety of passive andmore active uses.

    Landscaped courtyards located throughout theremaining areas of the site shall be designed to

    enhance the pedestrian experience either visually in thecase of private courtyards or physically wherepedestrians are expected to pass by on their way toother destination points.

    Public plaza space will be incorporated into thedevelopment as appropriate, either within the Central

    Green or along primary street frontage.

    All parks shall be designed to accommodate focal/public

    art features.

    actual art or a monetary contribution to helpprovide public art in a later phase of the project.In anticipation of the development by others of apublic art plan for the 10 acres located to thenorth of 12th Street-extended, a portion ofMetropolitan Parks total public art contribution

    may be allocated to art endeavors on thisadjacent parcel if such is determined to beappropriate during the art master planningprocess .

    A public art consultant shall be retained todevelop the concept plan. Public art features

    may include sculpture, fountains, specialtypaving or building details that have beenspecifically designed to promote art in the publiceye.

    Consideration shall be given to location of public

    art in relation to urban plazas, parks andpedestrian connections that are within the

    The building base shall relate to the adjacentstreet and sidewalk and be scaled to enhance

    the pedestrian experience. The base may becharacterized by light-colored masonry materialswith a darker water-table and an articulatedfaade for first floor residential uses, and the

    addition of windowed facades for ground floorretail uses. Cornices may be used to differentiatethe building base from the shaft. First floor heightshall be a minimum of 18 feet .

    The shaft may be designed as a darker f ield with

    lighter accents so as to reinforce vertical andhorizontal rhythms of the architecture and break

    the scale of the building.

    The building crown shall define the building atthe skyline and shall incorporate as appropriatearchitectural elements to create a memorableimage.

    Height and Massing

    The project site shall be organized around 3, 22-story

    buildings which will serve as anchors and referencepoints to the various phases in the development.

    Buildings shall generally taper with height variation andsetbacks as they approach streets, to provide variety at

    the street level, to compliment established developmenton opposite sides of public streets and to enhance openspaces within the project. The principle for tapering upfrom existing low rise residential will be adhered to, and

    used where appropriate to enhance open space areas.The height of individual buildings shall be determined ona phase by phase basis once overall project density hasbeen established by the County under an amended

    PDSP allocation. Height maximums shall be asindicated on the Framework Plan.

    Individual buildings shall follow massing and stylistic

    strategies of traditional classical buildings, such as thedivision into base, shaft, and crown. Building materialand color may vary from building to building so as toprovide variety.

    as to add interest to the skyline
