OMNNI Brownfield Redevelopment

Brownfield Redevelopment

Trolley Square
Appleton, Wisconsin


OMNNI conducted a Phase II investigation and site investigation at the former Valmet property for the Appleton Redevelopment Authority. OMNNI assisted in placing the site into the WDNR’s Voluntary Party Liability Exemption (VPLE) program and in securing two WDNR Site Assessment Grants to raze the on-site buildings and investigate the property. Since the property had been filled with foundry sand, an historic fill exemption was required from the WDNR before the property could be redeveloped.

OMNNI also assisted in allowing the site to be used as a staging area for the College Avenue reconstruction and streetscape project and as a staging area for a thermal treatment plant, which treated coal tar contamination from a site directly across the river. The use of the property for the staging areas not only saved the city considerable amount of money, but significantly reduced the impact of these projects on the local community. The site received a Certificate of Completion from the WDNR and was successfully redeveloped into Trolley Square, a 20,000-square-foot brick and glass mixed-use facility. The city received a certificate of appreciation for this project from Scott Hassett (former WDNR Secretary).
