Integrated judicial center shall be allowed as provided for herein and in the Table of Use Regulations, subject to the following provisions:
A. Table of Dimensional Standards.
(1) Minimum lot area: 60,000 square feet.
(2) Minimum front yard: 10 feet.
(3) Minimum side yard: five feet.
(4) Minimum rear yard: five feet.
(5) Minimum upper story step-back: 15 feet (above 3rd story).
(6) Minimum upper story step-back: 15 feet (above 5th story).
(7) Maximum floor area ratio: 450%.
(8) Maximum building coverage: 95%.
(9) Maximum building height: seven stories/112 feet.
(10)Minimum lot width at setback: 200 feet.
B. Additional height, bulk, and area standards.
(1) Upper story step-back. Four-story or higher buildings must step back upper stories by at least 15 feet measured from the face of the wall of the 3rd story (25 feet minimum measured from street or lot line). Six-story or higher buildings shall step back an additional 15 feet measured from the wall of the 5th story (40 feet minimum measured from street or lot lines). Required upper story step-backs may be reduced to a minimum of five feet measured from the face of the wall of the story below if they occur on a facade facing a side or rear yard only. Step-backs for integrated parking structures shall not be reduced. Step-backs on one or more of the first three floors that satisfy the intent of this Section are permitted.
(2) Horizontal building modulation. Building facades shall conform to the following standards:
(a) The maximum width (as measured horizontally along the building exterior) without building modulation shall be 60 feet. If the principal use of the building is for the parking of motor vehicles, there shall be a permitted tolerance of 5%.
(b) The minimum depth of modulation shall be the greater of six feet or not less than 0.2 multiplied by the height of the structure (finish grade to top of wall). The minimum width of modulation shall be 15 feet. When the principal use of the building is for the parking of motor vehicles, the depth of such modulation shall be a minimum of 3.5 feet. No modulations shall be required on a wall of a parking facility which does not front on a public street.
(c) Roof decks or balconies may be used as all or part of the building modulation.
(d) The requirements of the horizontal building modulation subsection shall be considered satisfied if existing building facades of contributing historic structures are preserved and incorporated into the proposed building. Building setbacks for stories 1 through 3 may be reduced to align with adjacent existing building facades and as otherwise permitted by
§ 513: Front Yard Reduction of this Chapter.
(3) Modulated roofline. Roofs are a design element and should relate to the building facade articulations. The roofline of all facades visible from a street or public park or open space shall be modulated according to the following standards:
(a) For flat roofs or facades with a horizontal eave, fascia, or parapet: change roofline so that no unmodulated segment of roof exceeds 60 feet. Minimum vertical dimension of roofline modulation is the greater of two feet or 0.1 multiplied by the wall height (finish grade to top of wall).
(b) For gable, hipped, or shed roofs: a minimum slope of three feet vertical to 12 feet horizontal.
(c) Other roof forms such as arched, vaulted, dormer, or saw-toothed may satisfy this design principle if the individual segments of the roof with no change in slope or discontinuity are less than 60 feet in width (measured horizontally).
(4) Building articulation shall be accomplished with design elements such as the following, so long as the articulation interval does not exceed 60 feet.
(a) Repeating distinctive window patterns at intervals less than the articulation interval.
(b) Providing a balcony or bay window for each articulation interval.
(c) Changing the roofline by alternating dormers, stepped roofs, gables, or other roof elements to reinforce the modulation or articulation interval.
(d) Changing materials with a change in building plane.
(e) Providing lighting fixtures, trellis, tree, or other landscape feature within each interval.
(5) Vertical articulation. To moderate the vertical scale of buildings, the design shall include techniques to clearly define the building's top, middle and bottom. The following techniques are suggested methods of achieving vertical articulation:
(a) Top: sloped roofs, strong eave lines, cornice treatments, horizontal trellises, etc.
(b) Middle: windows, balconies, material changes, railings and similar treatments that unify the building design.
(c) Bottom: pedestrian-oriented fronts, pedestrian scale building details, awnings, and arcades.
(d) Where appropriate, the applicant shall coordinate the horizontal elements (i.e., cornices, window lines, arcades, etc.) in a pattern and height to reflect similar elements on neighboring buildings that exhibit the Borough's desired scale and character.
(6) Building exteriors shall be constructed from high quality, durable materials. Preferred exterior building materials that reflect the Borough's desired traditional main street character are as follows:
(a) Masonry;
(b) Cast stone;
(c) Tile;
(d) Other materials subject to approval by Borough Council.
(e) If concrete or concrete blocks (concrete masonry units) are used for walls that are visible from a street, public park or open space or pedestrian route, then the concrete or concrete block construction must be architecturally treated in one or more of following ways:
1) Use of textured surfaces such as split face or grooved.
2) Use of other masonry types such as brick, glass block, or tile in conjunction with the concrete or concrete blocks.
3) Use of decorative coursing to break up blank wall areas.
(7) Fenestration. The arrangement, proportion and design of windows and doors (fenestration) shall conform to the following:
(a) The height to width ratio of single openings and group openings are to be proportionately scaled to the wall.
(b) Door and window details and trim suitably scaled to the wall.
(c) Reduce large expanses of glass used in windows and doors to smaller component windows reminiscent of traditional main street vernacular when adjacent to existing buildings, sidewalks or other pedestrian use areas.
(d) The total square footage of windows along a facade facing a street shall be a minimum of 15% of the square footage of the facade.
(8) Accessory Parking Structures. Accessory parking structures of two or fewer stories and that are within 300 feet of an Integrated Judicial Center may have a minimum front yard setback of five feet, and are exempt from modulation requirements of Subsection B(2), (3), (4), and (5) herewith, and as follows.
(a) The accessory parking structure is located within the Doylestown Borough Historic District and the design receives a certificate of appropriateness prior to final land development approval.
(b) Areaways and other subsurface light and air wells may be located within the required yard areas, providing their walls do not project more than 18 inches above grade. Fences and guardrails for these areaways may be up to 48 inches above grade but shall be a visually transparent design.
(c) All other dimensional and design requirements of the Integrated Judicial Center are met.
C. Parking. See "Vehicle Parking" above for details.
