Pittsburgh City Zoning Code

ARTICLE II

Base Zoning District

§ 903.01 General.

A. 
Purpose. Pittsburgh's overall character is defined to a great degree by its diverse and unique residential areas. The Urban Zoning Code's approach to residential zoning reflects this diversity by allowing very fine-grained adjustments in the range of zoning controls applied within and among neighborhoods. The purpose of these controls is to encourage development and redevelopment while preserving the character of existing residential neighborhoods.
B. 
Overview of Regulations. The residential zoning regulations of this chapter consist of a series of five (5) Use Subdistricts and five (5) Development Subdistricts. This approach results in twenty-five (25) possible residential zoning districts, each of which is regulated by combining a Use Subdistrict with a Development Subdistrict.

A. 
1. 
Purpose. The Allegheny, Monongahela, and Ohio Rivers and their riverfronts are valuable cultural and ecological resources of city-wide and regional significance that contribute to the public's economic, environmental, recreational, and aesthetic well-being. The City intends to improve the ecological health of its rivers and riverfronts for the benefit of the public through regulation of development along its riverfronts. Regulation through the Riverfront (RIV) Zoning District will limit potentially detrimental impacts near the riverfronts while allowing for high-quality, sustainable development and preservation of the diverse character of the City's riverfronts. The RIV Riverfront Zoning District is intended to promote development of the City's riverfronts in a manner that:
a. 
Acknowledges the historic diversity of uses, the varied character, and the economic value of the riverfronts;
b. 
Facilitates mixed-use development that physically and functionally integrates with the riverfront and strengthens pedestrian connections to the riverfronts;
c. 
Maintains and creates connections between the riverfronts and neighborhoods within the City;
d. 
Protects areas of industrial use from encroachment of incompatible uses;
e. 
Creates an environment that supports multiple modes of transportation;
f. 
Promotes sustainable development;
g. 
Improves of the ecological health of the rivers;
h. 
Conserves and enhances riverbanks and riverfronts;
i. 
Conserves, restores, and enhances native riverbank and aquatic plant life, improves river ecosystem health, and supports biodiversity; and
j. 
Improves the scenic qualities and the public's enjoyment of riverfronts by preserving, creating, and enhancing public views and access to the riverfronts.
2. 
RIV Subdistricts. To respond to the variety of development forms along Pittsburgh's riverfronts, the RIV District is divided into five (5) subdistricts that relate to the function, scale, character and use of different areas along the rivers. The subdistricts are as follows and are indicated in the RIV District Subdistricts map:
a. 
RIV-RM Mixed Residential Subdistrict. The RIV-RM Mixed Residential Subdistrict is intended for areas of higher density residential development.
b. 
RIV-MU Mixed-Use Subdistrict. The RIV-MU Mixed-Use Subdistrict is intended to foster a vibrant, connected mixed-use environment that may be designed either vertically within a single development or horizontally within a larger area.
c. 
RIV-NS North Shore Subdistrict. The RIV-NS North Shore Subdistrict is intended specifically to address the North Shore and its unique mix of large-scale sports, entertainment, and cultural uses. As a mixed-use district, high density residential development is also allowed.
d. 
RIV-GI General Industrial Subdistrict. The RIV-GI General Industrial Subdistrict is intended to address a variety of industrial uses. The district accommodates both general industrial uses, as well as heavier industrial uses that may produce external impacts such as smoke, noise, glare, or vibration. Outdoor storage and related outdoor activities may also be included in the operation of such uses. The subdistrict is structured to prevent encroachment of non-industrial uses, accommodate site design elements related to public safety, and maintain compatibility with surrounding uses.
e. 
RIV-IMU Industrial Mixed-Use Subdistrict. The RIV-IMU Industrial Mixed-Use Subdistrict is intended to address areas of the riverfront that are diversifying from their original, strictly industrial nature. It accommodates a variety of higher intensity uses, including light industrial, commercial, and high density residential development. The RIV-IMU Subdistrict is also intended for industrial areas that are focused on research and development and technology-oriented industries.
