The power of pop-ups: Strategic urban guidelines for indeterminate public spaces in New York city

Abstract

This study examines the interaction between informal food trucks and formal street-level open spaces in Manhattan, New York City, focusing on how food trucks influence the accessibility, use, and vitality of underutilized public spaces, particularly Privately Owned Public Spaces (POPS). By analyzing their spatial relationship, the research finds that informal vending activities can help activate leftover urban spaces, promoting pedestrian use and enhancing public life. The study proposes design and management strategies to integrate temporary pop-up facilities into formal urban systems, offering a flexible model to support inclusive, small-scale economies in dense environments.Using GIS mapping and data from NYC Open Data, Google Maps, and Yelp, Chapter 2 quantitatively analyzes the spatial relationships between food trucks and various categories of open spaces. Findings reveal a strong correlation between food truck activity and underused Privately Owned Public Spaces (POPS), highlighting their potential as spontaneous nodes of street life despite regulatory and design constraints. Chapter 3 explores the systemic causes behind the disconnect between POPS’ intended public function and their actual usage. It traces the evolution of incentive zoning policies and maps the network of city and private stakeholders to expose regulatory fragmentation and design shortcomings. Although separately managed, food trucks and POPS have developed an informal spatial coexistence, where vendors benefit from the visibility of adjacent open spaces while contributing to their activation. Chapter 4 offers design and policy-based strategies for integrating pop-up facilities into the planning and management of POPS. Proposals include a “Pop-up Corridor Program” in East Midtown and guidelines for adapting POPS typologies through temporary infrastructure and coordinated vendor management. These strategies reposition POPS as active components of a vibrant, inclusive public realm rather than passive byproducts of zoning policy. Ultimately, the study provides a design and regulatory roadmap for incorporating informal practices into street-level open spaces, demonstrating the power of pop-up interventions to revitalize indeterminate public spaces and strengthen urban public life.
