The City of Milwaukee and the Milwaukee Metropolitan Sewerage District (MMSD), has undertaken the transformation of the 30th Street Industrial Corridor. Elements of the project include addressing flooding issues within the northern portion of the corridor in the vicinity of Lincoln Creek. KSingh, as part of a consulting team, was retained by MMSD to take on this project. KSingh, as part of a consulting team led by CDM Smith, was retained by MMSD to take on this project.

A preliminary engineering study recommended the construction of stormwater detention basins and related conveyance infrastructure for the north section of the 30th Street Industrial Corridor. KSingh performed Phase I and II Environmental Site Assessments (ESAs).

The project challenges included many neighborhood concerns including: stakeholders who have investments in the area and managing large amounts of low level contamination in a cost effective manner.

KSingh has been retained to perform geotechnical and environmental engineering services for the project. The work concerns the areas identified as Bee Bus Basin, DRS North Basin, DRS East Basin, and the storm sewer conveyance alignment. Work is currently underway.

As part of the project, KSingh assisted the District in preliminarily identifying pathways to closure and costs in order to allow a fair price to be reached for the purchase of property.

Current work has identified contaminants of concern in soil and groundwater including PAHs, Pesticides, and RCRA Metals. A Soils Management Plan is being prepared which will direct how soils are handled in an environmentally responsible and cost effective manner. In particular, investigations are underway to identify a beneficial reuse site for soils with low-level contamination of PAHs.
