The Two MarketPointe Site, located at 4400 West 78th Street, was redeveloped as part of the MarketPointe Office Park, which includes the MarketPointe I property at 4300 MarketPointe Drive to the northeast. These two properties and the Three MarketPointe site at 4300 West 78th Street, proposed for future redevelopment, are collectively referred to as the “Overall MarketPointe Site.” Environmental concerns at the Overall MarketPointe Site were principally related to contamination associated with the former France Avenue Dump, whose western footprint extends onto the MarketPointe I and Three MarketPointe properties east and northeast of the Two MarketPointe Site.
Environmental issues and the cleanup process
The France Avenue Dump was mined for gravel and backfilled with fill and debris. Following its use as a dump, light industrial and commercial buildings were constructed on the Overall MarketPointe Site. These buildings were razed in the 1990s.
Environmental investigations to prepare for redevelopment were conducted throughout the Overall MarketPointe Site in 1998, 2002, 2005, 2006 and 2007. The investigations defined the location of waste and soil contamination, and found low levels of methane gas, likely originating from the France Avenue Dump, in limited areas of the Two MarketPointe Site.
Groundwater investigations at the Two MarketPointe Site detected volatile organic compounds and metals in groundwater, but below drinking water criteria.
Response actions were conducted during the summer and fall of 2007 to screen for potential impacted soils and waste during redevelopment of the site and to address potential methane gas concerns for the new Two MarketPointe Building and Two MarketPointe Parking Ramp as well as the underground utilities, including an underground stormwater-retention system. Construction monitoring included screening for methane gas and potentially impacted soils. Proactive construction activities to protect against potential methane vapor risks from the nearby former France Avenue Dump involved construction of vapor-control systems for the Two MarketPointe Building, including sealing utility penetrations with flexible boots, expanding foam and mastic; the use of commercial ventilation for the Two MarketPointe Building and Two MarketPointe Ramp; and venting of an oil/water separator in the Two MarketPointe Building.
During soil correction activities to remove organic soils at the southeastern portion of the Two MarketPointe Building, contaminated soil associated with old wooden pilings that were had been treated with creosote was encountered and excavated. Approximately 70 tons of soils impacted with polynuclear aromatic hydrocarbons were disposed at the Veolia ES Rolling Hills Landfill near Buffalo, Minnesota.
Redevelopment of the site
Ryan Companies US, Inc. was the developer and design-builder for redevelopment of the Two MarketPointe Building in 2007. The Two MarketPointe Building is an eight-story office building with one level of underground parking and a connected two-story restaurant building, the Two MarketPointe Parking Ramp, related utilities, surface parking driveways, and landscaped areas.
Two MarketPointe is designed to meet the US Green Building Council’s Leadership in Energy and Environmental Design (LEED) gold level standards for certification. The innovative property features include executive parking below the building, under-floor air delivery system, floor-to-ceiling windows, and raised floor panels. This project also created approximately 50 new jobs.
