(a) Purpose.
The Wissahickon /NCO intends to protect the existing walkable and aesthetic character of the Wissahickon section of Philadelphia. Walkability serves the health, safety, and general welfare of the citizens by providing human-scaled design, interesting and pedestrian friendly facades, and "eyes on the street", all in close proximity to useful commercial destinations, parks, and transit.
These blocks and streets were selected for their relatively intact historic pattern. The design of new buildings should be consistent with the character-defining features of this overlay district in terms of massing, vertical and horizontal articulation, fenestration proportions, and building materials.
The Wissahickon /NCO applies to properties in the area bounded by Henry Avenue, Hermit Street, Ridge Avenue, and the Wissahickon Creek, except for the parcels located in the /RAN Ridge Avenue Neighborhoods Overlay district, as shown on the following map for illustrative purposes only.

(c) Zoning Regulations for Residential and Residentially-Zoned Structures.
These regulations shall apply to residentially-zoned properties and to properties permitted by L&I for exclusive residential use.
(.1) Building Setback line.
The front setback shall be no further from the street than the furthest front facade of the principal building on any abutting lots on the same blockface and shall be located no closer to the primary street than the closest front facade of the principal building on any such abutting lots. If all such abutting lots are vacant, then the setback range shall be based on the building that is closest to the subject property and on the same blockface. Where there are not a sufficient number of lots that meet these criteria to establish a front setback, the front setback shall adhere to the standards set by the underlying zoning district.
(.2) Building Height.
(.a) If at least one abutting lot on either side of a house contains only two stories of habitable space, the stories above the second story of the house shall:
(i) Be set back an additional eight ft. from the minimum required setback; or
(ii) Incorporate a front facade mansard roof with a minimum slope of 15 degrees measured from the vertical plane of the front facade and a maximum dormer width of 7 ft., aligned on-center with second story windows below.
(.b) In no instance shall the maximum height of a house be greater than any house on an abutting lot with the same frontage that contains three stories of habitable space.
(.3) Porches.
Porches are permitted on all blocks and may be located in the required front setback. Porches shall be required if at least one of the immediately abutting lots with the same frontage contains a porch. Porches shall be a minimum of 5 ft. in depth, as measured from the front wall of the enclosed main structure, out toward the front property line.
(.4) Parking.
(.a) Parking in the front yard shall be prohibited.
(.b) Vehicular entryways of private residence parking garages that front on any street shall be prohibited, except when all immediately abutting lots with the same frontage contain existing structures with such vehicular entryways. In such instances, a vehicular entryway of a private residence parking garage that fronts on a street shall be permitted, provided it complies with all other applicable standards of this Zoning Code.
(.c) Curb cut width shall be limited to 12 ft.
(d) Design Standards for Residential and Residentially-Zoned Structures.
These regulations shall apply to residentially-zoned properties and to properties permitted by L&I for exclusive residential use.
(.1) The principal building shall have a habitable room on the front of the first floor with at least one entryway and one window facing the street. A habitable room shall be defined as in the Property Maintenance Code, Section PM-202.0.
(.2) New utility meters and HVAC equipment located on frontages shall be screened with landscaping, fences, or walls. Any other utility structures and their conduits facing a frontage shall be painted to match the wall or otherwise have their visibility minimized. This provision shall not apply to satellite dishes less than one meter in diameter or window air conditioning units.
(.3) Flush mounted windows shall be prohibited. Sills shall project from the wall a minimum of two inches.
(.4) Impervious Surface Coverage and Landscaping.
(.a) At least seventy percent (70%) of the front yard shall be covered with pervious planted material. 468
(.b) A street tree is required, in accordance with requirements of the Streets Department and the Department of Parks and Recreation.
(.5) Materials.
(.a) For new construction, the following front facade materials shall be prohibited: vinyl siding, aluminum siding, fiber cement siding, stone veneer, metal panels, and synthetic stucco.
(.b) Retaining walls and garden walls located along a street frontage shall not be constructed of concrete masonry units (CMUs) unless capped and covered with stone, cultured stone, stucco, or brick.
(.c) Fences or fence walls located along a street frontage shall be iron, stone, cultured stone, stucco, brick, painted wood, or finished wood. Chain link and vinyl fences are prohibited on frontages.
(.d) Windows in masonry, brick, brick veneer, or stone veneer walls, with or without stucco veneer, shall be inset a minimum of three inches.
These regulations shall apply to commercially-zoned or residentially-zoned properties used for commercial purposes.
(.1) Store frontages shall have a zero-step entry at the front door.
(.2) Store frontages shall have minimum fifty percent (50%) clear glass on the facade between the area 2 ft. and 10 ft. above the sidewalk.
(.3) Awnings on store frontages, if provided, shall be a minimum of 3 ft. in depth, as measured from the front facade of the building to the curb line.
