Purpose. The purpose of the SEO District regulations is to promote the development of a safe, inviting, and accessible commercial corridor along Pennsylvania State Route 51 that is easily navigable by vehicular traffic, bicyclists, and pedestrians. The regulations provide for a variety of streetscape amenities and design treatments including, but not limited to, sidewalks, crosswalks, street trees, and screened and pedestrian-friendly parking areas. The SEO District regulations shall serve as an additional series of site plan requirements applicable to the development, redevelopment, or alteration of commercial uses and properties, and are to be implemented with the site plan in addition to all standard requirements of the base commercial zoning district within which the property or commercial use is located. Other objectives include:
(1) Regulation of public and private improvements relative to commercial uses located in the corridor and to increase flexibility for site design.
(2) Implementation of long-term planning efforts and strategies for the corridor, including but not limited to the AIA Center for Communities by Design, Sustainable Design Assessment Team project for Allegheny County (2010).
(3) Management of the future development of strip-type, auto-dependent, commercial uses to minimize traffic conflicts and pedestrian safety problems and creation of an overall cohesive character for the streetscapes along the corridor.
(4) Enhancement of pedestrian circulation and pedestrian-oriented streetscapes through the use of sidewalks and pedestrian areas.
(5) Creation of consistent and cohesive streetscapes through the use of effective landscaping and screening.
(6) Definition of the character and identity of the corridor through the effective use of unified elements of the streetscape such as street trees, landscaping, hardscapes, street furniture, and accessory structures.
(7) Encouragement for the installation of landscape elements and visual screening of off-street parking areas.
(8) Promotion of green construction and maintenance practices so as to mitigate the environmental impact of development.
