December 2003 Final environmental Impact Statement, Lahaina Watershed Flood Control Project, Project Location Map.
Community Quote from Long-Term Planning Recovery Survey
This project will implement holistic stormwater and flood management, minimize stormwater runoff into the ocean and manage floodwaters across West Maui.
Drainage Master Plan Update (to address localized flooding in urbanized areas of Lahaina) and preliminary design for the flood control project (retention basins and diversion channels mauka of Lahaina). This project is supported through U.S. Department of Agriculture (USDA) Natural Resources Conservation Service’s (NRCS) Watershed and Flood Prevention Operations Program. The County Department of Public Works (DPW) is the local sponsor with Stantec as contractor. The project is currently working on a supplementary environmental impact study since the original Environmental Impact Statement was written in the 1980s, and a hydrologic and hydraulic study. Once studies are completed, USDA NRCS and DPW will discuss the data, needs and how the Lahaina Watershed can address the needs through feasible conservation practices, either structural or non-structural.
This project aligns with the current effort to develop a watershed management plan for Kahoma and Kaua’ula watersheds. Currently there is a lack of sponsorship for NRCS projects. The current contract NRCS has is for roughly $1.4 million, but additional funds are needed. This project will have to compete nationally for design funding.
