Additional and Optional Provisions Within the C-O Overlay District.
[Amended by Ord. 997, 12/16/2014; by Ord. 1014, 12/15/2015; and by Ord. No. 1098, 11/17/2020]
A. 
This subsection is established under the authority of Article VII-A of the Municipalities Planning Code, which promotes traditional neighborhood development within older infill areas, as well as other sections of such Code.
(1) 
The C-O Commercial Overlay District is hereby established, as shown on the map labeled Exhibit A. The C-O Overlay District establishes additional regulations that must be met for properties within the C-O Overlay District, in addition to the requirements of the underlying zoning district. In some cases, these overlay regulations relax requirements of the underlying zoning district. All of the regulations of the underlying C-2 and C-1A Districts and other provisions of this chapter shall continue to apply within the C-O District, except for regulations that are specifically added, made more restrictive or made more permissive by this subsection. If an applicant utilizes the taller height option that is allowed in the C-O District, then those additional standards shall continue to regulate the project over time.
B. 
As a conditional use, the Borough Council shall have the authority to approve a building in the C-O District to have a maximum height of 85 feet with no limit to the number of stories, provided the following additional requirements are met:
(1) 
Floor-to-floor height at ground-floor retail level shall be 15 feet minimum. Floor-to-ceiling height shall be nine feet minimum average for all stories above ground-floor retail level. Total building height, including parapets, elevator shafts, stairway access, or other rooftop structures, but not including mechanical equipment, shall not exceed 85 feet.
(2) 
The maximum height shall be 50 feet where an existing principal single family detached or two-family detached dwelling is within 125 feet of such building.
(3) 
Within the C-O District for a building using this height option, the maximum building height shall be measured based upon the average sidewalk elevation at the front lot line along a public street (excluding alleys), instead of using the height definition in § 27-202 of this chapter. In the event the lot line fronts two public streets (i.e., on a corner), the average sidewalk elevation for both streets shall be used to determine maximum height.
(4) 
Additional Height Standards.
(a) 
Rooftop structures such as parapet walls, chimneys, elevator shafts, and roof access structures are not exempt from the maximum building height requirement.
(b) 
Rooftop equipment necessary for the building functions and maintenance shall be exempt from the maximum building height requirement, provided the equipment is screened or integrated into architectural roof lines so as not to be visible from a height of six feet measured at the curbline (or edge of pave in the absence of curb) of the opposite side of any street, with the exception of public alleyways, at all points perpendicular to the applicant's property lines which abut a public right-of-way. Alleys, as defined in this Part, are exempt from this requirement.
(c) 
For the purposes of overall building height and story heights, a parking structure, or parking levels within a building, shall be regulated in the same manner as a building but shall be exempt from the minimum story height requirements in Subsection 4B(1) above.
(5) 
A story that is located completely below the level of the street along the front lot line shall be exempt from the minimum story height requirements in Subsection 4B(1) above.
(6) 
Parking Requirements. For each residential unit in the building, one parking space shall be provided within 1,000 feet of the nearest building entrance. Municipal lot permits do not count toward meeting this requirement.
(7) 
An applicant shall only be allowed to use this C-O taller height option if the applicant agrees to have the exterior design of a new principal building as viewed from a public street reviewed and approved under standards and procedures of the Borough Historic Preservation District Ordinance [Chapter 4, Part 2], even if the lot is not within the Historic Preservation District.
C. 
As part of the zoning application for any new principal building, the applicant shall submit architectural elevations showing the proposed design of the facade facing the street frontage and sides of the building visible from a public street. Such elevation shall describe the range of materials that are intended to be used. Where conditional use approval was required, if the Zoning Officer determines that substantial revisions have been made to the architectural elevation after conditional use approval has been granted, then the changes shall require another conditional use approval.
D. 
Where the majority of existing buildings on the same side of the same block of Main Street have a front yard setback along such street of 10 feet or less, then a minimum front yard setback shall not be required, and the maximum front yard setback shall be 15 feet.
E. 
A new building abutting Main Street shall meet the following additional requirements:
(1) 
The building shall include pedestrian doors and windows along Main Street and other public streets (excluding alleys), and shall include architectural details, articulation, trim, and a substantial decorative cornice.
(2) 
Windows shall be separated from each other so that the predominant siding material continues uninterrupted between them. In such case, the distance between windows should be no less than 2/3 of the width of adjacent windows.
(3) 
Individual window openings of sizes and proportions typically found in buildings constructed before 1950 along Main Street in the Borough shall be used, as opposed to more modern connected strips of windows.
(4) 
Mirrored glass shall not be used as an exterior building material.
F. 
An undeveloped lot with a property line abutting Main Street shall not be developed with a new building that has less than three habitable stories and that has a height as viewed from Main Street of less than 36 feet.
(1) 
A false facade greater than four feet above the roof shall not be permitted in order to comply with Subsection 4F of this section.
G. 
A new building located in both the C-2 and C-O Zoning Districts and fronting upon Main Street may include a zero foot rear setback along a rear alley and a 95% maximum building coverage.
H. 
No residential use shall be permitted for stories at or below grade at the primary street frontage.
5. 
Zero-Lot-Line Subdivisions.
[Added by Ord. No. 1131, 7/19/2022]
A. 
Zero-lot-line dwellings shall have no windows on the side of the dwelling which would directly face the adjacent attached dwelling.
B. 
Area Requirements.
(1) 
Lot Area. The minimum lot area required is 3,500 square feet.
(2) 
Lot Width. The minimum lot width required for each zero-lot-line dwelling is 30 feet.
C. 
Yard Setback.
(1) 
The required setback for front and rear yards are identical to those found in the specific zoning district in which the zero-lot-line development is located.
(2) 
The common-wall side yard setback is abated, with the opposite side yard setback being a minimum of 10 feet.
D. 
Maximum Lot Coverage. The total maximum lot coverage allowed (including accessory buildings) is 50%.
E. 
Where a lot abuts a public or private alley, all vehicular access shall be taken from the alley.

[As added by Ord. 677, 8/9/1989, § 3]
1. 
Existing Dwelling Units. Properly permitted dwelling units in existence at the date of the adoption of this section shall not be subject to the requirements of this Part as long as the number or area of the dwelling units is not altered.
2. 
Change in Requirements. Whenever there is any change in the number of dwelling units or area of the dwelling units, new construction, or conversion, the requirements of § 27-502, Subsection 3 or 4, shall be met.
3. 
All one bedroom dwelling units for one or two individuals, including efficiency apartments, shall contain an area of not less than 500 square feet of dwelling unit area.
