Ko'olaupoko Watershed Restoration Action Strategy 2007

The purpose Watershed Restoration Action Strategy (WRAS) is to serve as the master
plan for the Kailua Bay Advisory Council (KBAC, parent company of Hui o Ko'olaupoko) and provide direction for implementation of Best Management Practices (BMPs), restoration, monitoring,
education and outreach in the Ko’olaupoko area of windward O’ahu, Hawai‘i. The WRAS integrates the Environmental Protection Agency (EPA) nine-priority elements to assess watershed health.

Specifically, objectives for the WRAS are to:
  • guide KBAC and other community organizations and agencies in future implementation projects
  • serve as a planning tool that Ko‘olaupoko communities can use to improve water quality for their watershed area
  • address the State of Hawai‘i’s watershed planning criteria

As an approved WRAS, projects identified within the plan are given priority consideration (to the extent practical) for funding under the State’s 319(h) program established pursuant to the federal Clean Water Act.

Ko'olaupoko Urban Sub-basin Action Plan

Increasingly, HOK is focusing on non-point source (NPS) pollution and urban runoff as an important
component for watershed restoration. As such, HOK realized the need to prioritize opportunities for
future implementation of projects. The purpose of creating the USBAP is to clearly identify and prioritize
Low Impact Retrofit (LIR) projects and assess urban areas for improved pollution prevention within the
Ko‘olaupoko moku.

Low Impact Retrofit projects are defined as landscape features which use green infrastructure principles and ideas to manage storm water within a confined urban space. Low Impact Retrofits are intended to address NPS pollution by capturing and treating storm water on-site. The use of LIR can effectively reduce NPS pollution loading on receiving waters. 

Through this document, two-hundred twenty (220) sites were identified and ground-truthed resulting in a total of sixty (60) sites being ranked candidates for Low-Impact Retrofitting.

Hawai‘i Residential Rain Garden Manual

The purpose of the Hawai‘i Residential Rain Garden Manual is to teach residents of Hawai‘i the procedure of building a rain garden leading to the protection of Hawai‘i’s natural resources.

Rain gardens have the ability to reduce the amount of pollution entering streams and the ocean by intercepting stormwater. Rain gardens are ‘designed with nature’ as they mimic natural processes by treating and infiltrating stormwater into the ground and evaporating it back into the air, much like undeveloped areas.

The Manual will provide homeowners enough information to safely design and construct a rain garden based on historic rainfall patterns, soil properties and drainage areas. Additionally, this manual can easily transfer to schools or more developed urban areas to construct a rain garden. If, after reading this Manual, you are still unsure about how a rain garden should function, proper location or if your site is a good candidate for a rain garden, please contact Hui o Ko‘olaupoko.
