Potential Regional Sediment Management (RSM) Projects in the Haleiwa Region, Oahu, Hawaii

Abstract

This Coastal and Hydraulics Engineering Technical Note (CHETN) provides a summary of Regional Sediment Management (RSM) opportunities in the Haleiwa Region on the island of Oahu, Hawaii. The intent of this CHETN is the identification of potential RSM projects (PRPs) within the Haleiwa Region. Regional Sediment Management (RSM) refers to the effective use of littoral, estuarine, and riverine sediment resources in an environmentally sensitive and economically efficient manner. RSM changes the focus of engineering activities from the local or project-specific scale to a broader scale that is defined by natural sediment processes. A prime motivator for the implementation of RSM principles and practices is the potential for reducing construction, maintenance, and operation costs of federally authorized projects while increasing benefits. Implementing RSM principles also has the potential to positively impact linking multiple projects in their ability to realize authorized purposes. RSM was officially implemented at the U.S. Army Corps of Engineer (USACE) Honolulu District (POH), Honolulu, Hawaii, in February 2004. Honolulu District s overall RSM strategy is to investigate RSM opportunities along all regions in Hawaii. To date, Hawaii RSM has been instrumental in quantifying coastal processes and identifying sediment related issues in various regions shown on Figure 1: (a) Island of Oahu (Mokapu Point to Makapuu Point (SEO), and Diamond Head to Pearl Harbor (D2P)); (b) Island of Kauai (Poipu and Kekaha); and (c) Island of Maui (Kahului and Kihei). The Honolulu District s RSM focus in Fiscal Year 2013 (FY13) was the Haleiwa Region on the north shore of Oahu. Figure 2 shows the sub-regions that comprise the region. From left to right in the figure, these sub-regions are (a) Kaiaka Beach, (b) Alii Beach, (c) Haleiwa Small Boat Harbor (HSBH), (d) Haleiwa Beach Park (HBP), and (e) Puaena Point Beach.
