The Windward Ahupua'a Alliance plans one of its "quick and dirty" cleanup sweeps Sunday at the edge of Kawai Nui Marsh. The group meets at the bridge near the entrance to Kailua.

The cleanup effort, which alternates on different sides of the marsh each month, runs only from 12:30 to 2 p.m.

There's a pau hana party, too, immediately afterward, at the new Kalapawai Market in Kailua town, which will include discussions about a possible new effort to help restore Kailua Bay to its former glory. Interested residents are seeking an organization to lead that effort.

Other upcoming cleanup dates are April 1, May 6 and June 3.
