About


Program Overview

In 2006, O‘ahu voters approved a Charter amendment directing one-half of one percent of the City and County of Honolulu’s annual real property tax revenues to be deposited into the Clean Water and Natural Lands (CWNL) Fund for the acquisition of real estate or any qualified interest therein for land conservation on O‘ahu. The City formally established the CWNL Fund in 2007.

In 2016, O‘ahu voters approved a Charter amendment to establish the CWNL Advisory Commission (the Commission) to review qualified proposals and make recommendations to the City Council for the expenditure of the CWNL Fund.

In 2022, a Charter amendment expanded the use of the CWNL Fund to include costs related to the operation, maintenance, and management of lands that have been acquired with the CWNL Fund.

In 2025, the Conservation Office (the CO) was created within the Department of Housing and Land Management (DHLM) to provide administrative support to the Commission and to oversee acquisitions and related conservation transactions or activities. In doing so, the City acquires real property interests in land and the CO works to ensure ongoing compliance with CWNL Fund requirements.
