With the goal of stopping the damage done by repeated 'uncontrolled' storm runoff at the south end of Napili Bay, we focused on repairs to the desilting basin. 

WHAT?:

  • Designed (donated by NRCS) and installed a tri-level outlet valve on the desilting basin

  • Installed a grassed waterway (NRCS & MCDPW) to slow and filter runoff from basin

  • Installed two outdoor educational signs

    • "Respecting Coral Reefs" 

    • "Malama Kahawai" (original design) 

  • Project completed and blessed, Fall 2011


WHY?:

  • Silt and debris deposits have damaged our reef after heavy rainfall events 


  • Storm runoff was not retained in the basin to settle out


NOW:

  • No new stormwater runoff from basin into Napili Bay since January 2012!
