Notified in 2017, the One Plan is the “one stop shop” resource management planning document for the Horizons Region. It combines the Regional Policy Statement, Regional Plan and Coastal Plan.  The One Plan defines how the natural and physical resources of the Region, including fresh water, air, productive land and natural ecosystems, will be cared for and managed by the Regional Council in partnership with Territorial Authorities and the community. 

Part I is the Regional Policy Statement. It sets out regionally significant resource management issues, and outlines objectives, policies and methods that will address them.

Part II is the Regional Plan, which includes the rules for natural and physical resource use in the Region.

Proposed Plan Change 2 (PPC2)

In 2017 an evaluation of the policy for managing nutrients in Horizons’ Regional Plan (the One Plan) demonstrated that a problem exists within the regulatory framework. Proposed Plan Change 2 (PPC2) will recalibrate Table 14.2 with OVERSEER version 6.3.0 and focuses on the controlled activity pathway for managing nutrients. The aim is to notify PPC2 by the end of 2018.
