Laughlin and later, its parent company, LTV, when it closed in 1998. According to a December 23, 2008, article in the Pittsburgh Post-Gazette, Dimperio's Market, the only full service grocery store in Hazelwood, would close because of shoplifters. Neighborhood Revitalization Mirroring Pittsburgh's overall decline, Hazelwood suffered a significant population loss and disinvestment following the decline of the steel industry and the final shuttering of the LTV Coke Works in 1997. However, the purchase of the 178-acre vacant brownfield site in 2002 by Almono LP (at the time composed of four Pittsburgh foundations) marked the beginning of a new era for Hazelwood. Since then, the neighborhood and community have organized to reinvest and revitalize their main street - Second Avenue - with new local-serving retail, stabilize and improve housing stock and affordability, and ensure redevelopment of the vacant 178-acre site is a positive catalyst for the neighborhood. These reinvestment efforts are often aided by the same foundations that compose Almono LP and own Hazelwood Green: the Claude Worthington Benedum Foundation, The Heinz Endowments, and the Richard King Mellon Foundation. On January 8, 2019, the amended SP-10 Zoning Ordinance was passed by City Council for the 178-acre site, Hazelwood Green. This Zoning Ordinance amendment accompanied the new Preliminary Land Development Plan (PLDP), which was approved on September 11, 2018 by Pittsburgh Planning Commission to replace the plan of record. The PLDP provides a core framework with flexible programming and development approaches to make the site adaptive to fast shifting externalities. The PLDP has been designed (and registered with USGBC) to meet LEED for Neighborhood Development Plan standards, with an expectation to reach Gold certification in 2019. The plan calls for approximately 8 million square feet of development that would be home to 5,000 residents and approximately 15,000 employees. To date, much of the horizontal development of Hazelwood Green has been completed, including: preliminary remediation, mass grading, new streets and utilities, and stormwater management system. After decades of being closed to the public, the site's new streets - extensions of Hazelwood Avenue and Blair Street - were publicly dedicated and opened to the public on April 1, 2019. This was followed by the first tenants moving into the new building at Mill 19 in Summer 2019. In 2020, the site's first public open space - the Plaza - is expected to be completed and opened to the public, along with additional buildings opening.
