Pittsburgh Zoning Map - RIV Zoning Max Height

By Carolyn Ristau

Introduction

Pittsburgh’s interactive zoning map includes many layers besides the zoning districts, most of which relate to requirements within or adjacent to the zoning code. For an overview on how to use the interactive zoning map, see our introductory post.

To select different layers, click the stack of paper in the upper right corner. The layers available are listed below. Today’s post features the RIV Zoning Max Height layer, pictured above and in bold text below.

The RIV Zoning Max Height Layer

Overview

This layer of the interactive zoning map shows the maximum permitted heights for areas of the city in the Riverfront (RIV) zoning districts. To see the maximum permitted height:

• Use the arrows to navigate between the pop-up windows as necessary

Relationship with Zoning

Most of Pittsburgh’s zoning districts include a maximum height requirement that is consistent throughout the district. The RIV zoning districts (RIV-RM, RIV-MU, RIV-NS, RIV-GI, and RIV-IMU) follow a different pattern. The starting point for the height requirements in the RIV zoning districts applies across all five districts with a minimum 24’ and maximum 60’ height thresholds for Primary Structures (905.04.E.3). From there, the height map layer indicates areas where the maximum height is reduced to 45’ and where the height may exceed 60’ provided the conditions enumerated in 905.04.E.3 are met.

Note: this pattern of separate map layers for uses and height harks back to the early zoning standards in Pittsburgh. The 1927 zoning map used separate layers to regulate permitted uses, maximum height thresholds, and area standards.

Challenges

In other districts, either the proposed project meets the maximum height requirement or it doesn’t; if it doesn’t, a variance may be requested from the Zoning Board. In the RIV zoning districts, the maximum height a particular project is permitted to reach is based on the location, design, programming, and provision of community assets. Additional documentation, such as a shadow study, will likely be required as part of the application to demonstrate compliance with the requirements for heights beyond 60’.

Conclusion

The RIV Zoning Max Height layer is a key starting point for determining the maximum height permitted for a project in one of the RIV zoning districts. Start with Pittsburgh’s interactive zoning map to check the maximum permitted height where the project is located. Then, refer to the height standards in the zoning code (905.04.E.3) to determine how the project can reach its ideal height within the maximum threshold.
