Stormwater Solutions

K&A works with municipalities, drain commissioners, educational institutions, communities, developers, and non-profit organizations to address stormwater management needs, conducting stormwater studies and implementing projects to reduce the effects of stormwater on the environment.

As issues surrounding stormwater permitting and rulemaking continue to garner attention nationwide, K&A is dedicated to partnering with diverse clients to conduct stormwater studies and implement stormwater solutions.

Full reports for many of our projects are available on the Technical Reports page.

Featured Projects

Western Michigan University (WMU)

TMDL Compliance and Stormwater Neutral®:

K&A has been assisting WMU on a variety of water resource issues for more than a decade. K&A has provided technical assistance on numerous stormwater Best Management Practices and low impact development (LID) projects. K&A prepared a TMDL compliance plan to evaluate environmental benefits to the campus, such as stormwater loading and volume reduction. A metric tracking system was put in place to plan for future improvement, assisting WMU with becoming the first MS4 to meet their Stormwater Neutral® goal.

Kalamazoo Valley Community College (KVCC)

Stormwater Management and Upgrades: 
An EPA Section 319 Grant awarded in 2011 provided funding for a stormwater treatment project to eliminate stormwater runoff associated with a single, remaining untreated outfall to the West Fork Portage Creek.  K&A provided engineering and design services for this project.  They also assisted with grant acquisition.  The benefits from this project included stormwater treatment of 92 acre-feet/year, native vegetation covering approximately four acres, over 6,000 native plants and shrubs, permanent educational signage, educational curriculum development, elimination of the MS4 permit, and compliance with TMDL goals.  KVCC has since continued their efforts to become the second Stormwater Neutral® verified MS4 in the area in 2016.

Michigan State University (MSU)

Stormwater Management and Wetlands:
In 2001, MSU expanded its 36-acre Commuter Lot #89, making it the largest commuter parking lot in the county. Working with URS Corporation, designers of the parking lot, K&A designed an innovative stormwater treatment process for this site. The result was an in-line treatment system of successive BMPs with treatment discharge waters incorporated into wetland enhancement 
creating multiple habitats and increased diversity. The system resulted in the elimination of all previous stormwater discharges from the original lot to the impaired Red Cedar River with a capacity to detain back-to-back 10-year storms.

City of Portage, Michigan

Portage Consolidated Drain Project:
K&A initially conducted a feasibility study that ultimately led to their design and oversight of a $4.7 million regional stormwater treatment system know as the Consolidated Drain Project in the City of Portage. This 25-acre regional stormwater treatment system serves over 463 acres of a highly commercialized urban core. The system includes several acres of wet detention, constructed wetlands, public trail ways, educational features, and habitat enhancements to improve water quality and fisheries of the upper Portage Creek, a designated cold-water trout stream.
