A. 
Purpose. The Riverfront Development District is a mixed-use district which is intended to facilitate the redevelopment of large, underutilized or vacant, former industrial sites along the Monongahela River which may be suitable for a variety of large-scale commercial, residential and flex office uses, provided that the arrangement and design of those uses are carefully planned and implemented. These regulations are further intended to allow considerable flexibility within the RDD in the specific types of uses, their arrangement and their intensity while assuring that:
(1) 
Uses are either compatible in scale, intensity, visual and operational characteristics or, if different, are so arranged that adverse impacts on adjacent properties are minimized.
(2) 
All necessary utilities, facilities and site improvements are provided in accordance with the requirements of the Borough's Subdivision and Land Development Ordinance, Chapter 389.
(3) 
Negative environmental impacts are avoided.
(4) 
Provision is made for the safe movement of people, goods and vehicles without increasing congestion or creating hazards within the RDD or within the area of impact in the larger community.
(5) 
Each building site has adequate off-street parking and loading facilities, safe pedestrian circulation, light and air, access for emergency vehicles and landscaped areas and open space as may be required by other articles of this chapter.
(6) 
The improvement and use of land within the RDD does not adversely affect existing development in adjacent areas.
B. 
Community development objectives.
(1) 
Development within the RDD should be physically integrated with the community in the following ways:
(a) 
A system of public or approved and improved private streets should be constructed in a way so as to ensure coordination with the Borough's Land Use and Thoroughfare Plan.
(b) 
All utilities should be designed and installed in a manner which ensures coordination with the infrastructure systems serving the Borough.
(c) 
Pedestrian and vehicular access to the riverfront should be provided through the RDD.
(d) 
Land uses along the riverfront which permit public access to the river should be encouraged.
(2) 
In order to enhance the Monongahela River as a scenic and recreational community resource, the following criteria shall be adhered to:
(a) 
Development is encouraged which is visually and aesthetically oriented toward the river by enhancing views and creating new ones.
(b) 
Development shall provide for the establishment and maintenance by each individual abutting property owner or an owners' association of a landscaped buffer area which is not less than 25 feet in width measured from the river's edge at "normal pool"; this requirement may, however, be waived by the Borough for water-dependent uses, provided that alternative plans for access to the riverfront have been approved by the Borough.
(c) 
Development shall focus on water-dependent and water-related uses along the river by creating a balance of retail, residential, office and recreational uses which will bring residents and visitors to the riverfront.
(d) 
Development shall include a wide variety of waterfront spaces such as promenades, plazas and tree lawns for walking, jogging, shopping and dining, as well as for sitting and quiet contemplation.
(e) 
Public spaces shall be designed to fit the changeable nature of the riverfront on a daily, seasonal and annual basis.
(f) 
Riverfront spaces shall be designed for public events and celebrations.
(g) 
Public access shall be clearly defined by emphasizing the line of the riverfront's edge with pathways, promenades and plazas that give immediate and continuous public access along the river while defining its physical boundary.
(h) 
Public access to the riverfront shall be highlighted with visual links such as pedestrian-oriented streets and sidewalks, plazas and view corridors, as well as appropriate site planning and building design.
(i) 
The site's history shall be celebrated by incorporating that history into street and building design. The site's history should be told through informative signage and public spaces for periodic events and historical celebrations.
(3) 
Development within the RDD should, to the extent possible:
(a) 
Provide employment opportunities at wage rates substantially above established minimum standards for area residents, particularly residents of Munhall.
(b) 
Contribute to the creation of a diversified job base within the community, with an emphasis on health, education and other service-oriented industries, advanced technology firms, the recreation industry and other more traditional manufacturing firms.
(c) 
Contribute to the long-term stability and growth of Munhall's tax base.
