What: project to remove ~ 1200 cu yd of excess sediment accumulated in Kūlanihākoʻi gulch above the highway.
When: anticipated for early July 2023, contractor work lasting 1–2 weeks
Why: fine sediment in streams and gulches moves downstream when it rains negatively impacting our coastal waters
and the corals and fish that need clean water to thrive.
Other benefits: flooding reduction in North Kihei by restoring some capacity in the channel.
Where: an approximately 1000ft stretch of gulch above the highway, 25–35ft wide, top layer where fines are
concentrated.
Permits: DLNR CWRM & US Army Corps do not require for maintenance activities performed as specified in this project;
maintenance activities are about the SMA. Conservation Plan updated and filed with NRCS for stabilization of soil on
ranchland
Orange box shows area where gulch maintenance will take place. Removed sediment will be spread on ranch lands, planted with forage seed and watered to reestablish vegetated cover. Follow the link below to zoom in.
