City of Portage Consolidated Drain Stormwater Quality and Trailways Facility

In a unique project, a regional stormwater treatment system for Consolidated Drain # 1, identified as the single largest contributor of nonpoint source pollution to Portage Creek, has been constructed, which will significantly increase the quality of life for city residents and biota in Portage Creek while meeting and exceeding regulatory requirements. The drain provides treatment for runoff from 463 acres within the highly commercialized urban core and targets 80% pollution removal rates. Its design integrates several large-scale stormwater treatment options, including a sediment pond, wet detention basin and both existing and created wetland treatment areas. More than a mile of accessible scenic trailways, bridges and overlooks, integrated into the site plan, now connect major retail and recreational facilities. Trailways also provide limited access to the 25 acres comprising the stormwater treatment area.

Voluntary stormwater permit and analysis of Goldsworth Valley Pond at Western Michigan University

K&A performed investigations of Goldsworth Valley Pond and surroundings with regard to current water quality conditions, existing and future capacity for storm water detention, need for dredging and biological diversity. Recommended options for improvements have been submitted and several are pending implementation. An Application for coverage under a Voluntary Storm Water Discharge Permit (MIG 610000) was prepared by K&A and submitted by WMU to the MDEQ as part of their continuing commitment to demonstrate that locally driven efforts will be effective in addressing wet weather issues. Work related to this permit is pending the approval process.

Stormwater treatment system for Woods Lake, Kalamazoo

After submitting the 1997 Woods Lake Water Quality Study Report, Kieser & Associates, along with their engineering team member, URS Corporation, has initiated implementation of several key lake restoration elements. The first of these includes the creative development of a stormwater detention/wetland treatment system for nearly two-thirds of the lake's drainage area. Constrained by a very limited site area, system design included detailed meteorological and hydraulic analyses to determine optimal sizing of the treatment facility. Such efforts resulted in a treatment system one-third the size of that prescribed for a 5-year design storm yet capable of still treating nearly 98% of all storms.

Stormwater treatment from the U.S.'s largest commuter parking lot at Michigan State University

Among the services provided by K&A were coordination of input from, and updates to faculty and administrators, soils, hydraulic and vegetational analyses, conceptual storm water treatment system design and engineeering, hydrologic modeling, water quality monitoring, wetlands delineation, wetlands mitigation design, plantings recommendations and design and preparation of all required permits.

Maple Street School Rain Garden, Axtell Creek

Kieser & Associates served as the technical consultant to identify a location for the project, design the rain garden and oversee the construction. A rain garden capable of capturing up to a 2-inch storm event from roof top areas over the gymnasium, cafeteria and some classrooms was designed. The project has received notable publicity in local publications.
