Midtown at Clear Creek

Our client could not develop this parcel without navigating the compliance minefield of various solid waste, groundwater and surface water quality regulations.

Client

Brookfield Residential

Project Status

Completed, 2017

Buried solid waste from previous bridge demolition made it imperative that materials management simultaneously demonstrate compliance and proper due diligence while reducing/minimizing exposure to stormwater.

WSP USA served as Brookfield’s environmental consultant and stormwater compliance administrator. The property slated for residential development had previously been used for manufacturing parts and supplies for the aircraft industry and therefore had impacts to be addressed during construction.

WSP guided Brookfield through a construction stormwater discharge permit audit, recommended stormwater runoff control measures to minimize pollution from potential historical sources and prepared a stormwater management plan. Our team navigated through Colorado Department of Public Health and Environment regulations and reporting requirements and worked with Brookfield to determine the potential need for long-term treatment of low concentrations of trichloroethylene in the groundwater and provided design options.

Runoff control measures were designed and implemented to limit discharge to surface waters and to isolate stormwater from potential pollutant sources. In addition, beneficial use permits were obtained to incorporate select materials into open spaces and park areas, thus reducing wastes requiring disposal. Brookfield was able to develop the property and sell it to future retail or residential building partners.
