MANASSA, VA—Corporate Office Properties Trust has secured two long-term leases for two 150,000-square foot build-to-suit shell buildings on land it recently purchased in the Southpoint Business Center. The REIT will begin development here next month.

CLAYMONT, DE—Commercial Development Co., a commercial real estate and brownfield redevelopment company in St. Louis, has acquired a 425-acre, environmentally-distressed, former steel mill here from steel manufacturer Evraz. CDC and Environmental Liability Transfer, an affiliate of CDC, have assumed responsibility for the legacy environmental liabilities associated with the site and its former operators. Evraz acquired the property in 2007 and continued the near century-long steel manufacturing operation until 2013, when it shut its doors for economic reasons. EnviroAnalytics Group, another CDC affiliate, will begin remediation for the soil and groundwater and begin environmental monitoring—projects that will last two years.

EAG is working with the Delaware Department of Environmental Resources and Environmental Concerns to finalize the remedial plan under the state's voluntary cleanup program. At the same time CDC will be performing land studies, market assessments, and meeting with community stakeholders to determine the best use for the site.
