É«É«À²

Since 1998, concerted efforts by É«É«À² to address stormwater runoff from their campus footprint and adjacent areas contributing stormwater to É«É«À² infrastructure, as well as community investments through matching grant funds have paid dividends for local water quality in the Portage-Arcadia Creek drainage area. Accomplishments include:

• É«É«À² stormwater treatment projects within their MS4 campus footprint, achieved the 50% TMDL reduction in 2013 from their 1998 baseline annual load of 764 pounds.
• To date, these on-campus projects have reduced their annual TP loading footprint to 175 pounds from the 1998 baseline (a 77% reduction).
• Stormwater treatment areal coverage has increased from 236 acres in 1998 to 488 acres in 2021 out of 619 acres on the Main É«É«À² campus; a 52% improvement over 2011 treatment coverage.
• É«É«À²â€™s treatment of runoff from areas adjacent to campus not under their control contributing additional runoff to their infrastructure, and off-site project investments have achieved an annual load reduction of 968 lbs/year to the Portage-Arcadia Creek watershed and downstream Lake Allegan.
• Overall load reductions since 1998 achieved a zero-discharge Stormwater NeutralSM status for total phosphorus by 2013.
• Continued É«É«À² commitments to address remaining untreated areas on their campus and adjacent areas have now surpassed the zero-discharge goal by more than 200 pounds/year.
• Reductions since 1998 represent capital improvement expenditures of over $5.8M in stormwater retrofits and new treatment infrastructure; portions of this investment coming from university and technical partner persistence to pursue grant funding.
• Local stormwater infrastructure improvements led by É«É«À² have resulted in significant stormwater volume reductions that have mitigated severe wet weather flooding events on compus and in downstream urban areas of the City of Kalamazoo along Arcadia Creek.
• É«É«À² continues to pursue local water quality improvements by integrating low impact development and green infrastructure on all future campus renovations.
• Large, regional treatment opportunities still exist on-campus that have been conceptually designed and targeted for grant fund implementation support.
