HDOT and County of Maui

This session will offer valuable insights into the BMP inspection process conducted by both the State of Hawaii Department of Transportation and County of Maui. We will review the regulatory requirements for project BMP implementation, outline what inspectors look for during site visits, and discuss how to avoid potential enforcement actions resulting from non-compliance.

DOH Clean Water Branch

The DOH administer and enforce the statewide water pollution laws to protect public health and the environment. This goal is achieved by prohibiting discharges that affect water quality, keeping Hawaii’s waters fishable and swimmable for everyone. The DOH has developed a presentation that explains violations that may result in an enforcement action.

HDOT and EnviroServices

This session will provide a practical refresher on the 2022 Post-Construction Best Management Practices (BMP) Manual, highlighting key updates and differences from the 2015 version. Attendees will be guided to available online resources and introduced to updates made to the PCBMP Design Checklist and Compliance Tracking Spreadsheets. Includes a Hawaii Department of Transportation Highways Maui District project case study: the Kaʻahumanu Avenue Drainage System Improvements project.

Kennedy Jenks is assisting the County in this effort, including project timeline and proposed rule changes.

Maui Nui Marine Resource Council

Maui’s nearshore waters are increasingly impacted by polluted runoff and poor stormwater management. This presentation highlights MNMRC’s Reef Friendly Landscaping Program—a community-driven solution that reduces nutrient and sediment runoff through sustainable landscaping practices.

This project designed a hydrodynamic separator and biofiltration curb extension to treat stormwater on Akiohala Street in the Kaelepulu watershed to reduce pollutants currently being discharged into Kaelepulu Pond in Kailua, O‘ahu.

The Nature Conservancy

The 939-acre Olowalu reef has been identified as one of the most essential reefs to protect on the island of Maui. This talk describes ongoing work to inform coastal management, wetland restoration and sediment mitigation projects in the Papalaua to Olowalu stretch of coastline.
