The Greenprinting Process

Timeline at-a-Glance

Spring-Winter 2013: Community Engagement and Current Conditions Review

In developing the Greenprint, TPL first completed a current conditions review of Olahu. The TPL and ОНА (project team) built on that research through community outreach including SpeakOuts, interviews, and Island Leadership Team meetings. Through this process, the project team was able to establish the value residents place on important cultural, recreational, and natural resources on Olahu. A Technical Advisory Team (TAT) was created to guide the mapping process. Please see the Acknowledgments section for the full list of attendees at Island Leadership Team meetings and members of the Technical Advisory Team.

• Fall 2013-Winter 2014: Mapping Conservation Values

GIS mapping experts from both TPL and ОНА worked with the TAT to collect data, refine that data, and integrate it with the community-developed values to create maps identifying the best opportunities for land protection throughout Olahu.

• Spring 2014: Island Leadership Team Creates an Action Plan for Realizing the Greenprint

The project team compiled action ideas from the public outreach process and presented a draft action plan to the Island Leadership Team in March 2014. The ILT offered suggestions for refining the action plan for realizing the Greenprint in June 2014 and confirmed the Greenprint maps.

• Summer 2014: Finalize Greenprint Results

The project team created and placed the mapping site on-line and developed final materials.

A. Current Conditions and Community Engagement

Current Conditions Review

In order to develop the Current Conditions Report, The Trust for Public Land staff collected and synthesized background information. This information included related planning efforts such as local sustainable community and development plans, water management plans, state planning and economic development efforts, and demographic trends. The report provided context throughout the planning process and informed the project objectives, mapping analysis and action plan.

Community Engagement


A SpeakOut is an interactive display where organizers can share informative materials on an issue and participants can express their views and provide their feedback in an informal and cooperative environment. In order to understand the community’s conservation priorities, ОНА and The Trust for Public Land worked with Townscape, Inc. to develop and host a booth at several community events throughout Olahu in a “SpeakOut” style format. At these events, staff shared information on conservation and Greenprints with event participants and feedback was solicited on specific questions.

The Olahu Greenprint team attended 12 events from May through December 2013, hosting booths in a “SpeakOut” style format. The goal was to solicit ideas and share information about the Greenprint with residents throughout the island’s eight planning districts at community events, rather than through formal public hearings.

The project team solicited feedback in a variety of ways including through surveys (hard copy and on-line), mapping exercises, voting on conservation value priorities and even drawing pictures of favorite outdoor activities for keiki (children). A total of 910 surveys were completed, 784 at the SpeakOuts and 126 online. In the survey, participants were asked several questions to gain an understanding of the types of land most important to protect. Responses painted a picture of what residents value most about 0‘ahu, what lands are at risk of changing, and what people want for their island over the next 25 years.

The Island Leadership Team

The project team developed a stakeholder committee called the Island Leadership Team, comprised of more than 90 experts and interested residents. This team met in July 2013, October 2013, March 2014, and June 2014.


The project team completed 25 interviews by phone and in-person throughout Olahu with stakeholders during the fall of 2013. The vast majority of these interviews took place in person in Honolulu from October 25-November 1, 2013. Through these interviews we received advice and candid feedback about what a successful Greenprint would entail and how to ensure this project and plan are implemented toward that goal.

In total, we estimate that that the O'ahu Greenprint Team reached more than 1,300 people through this public engagement effort.

Mapping Conservation Values

Geographic Information Systems (GIS) analysis uses satellite photos, aerial photos, and on-the-ground verification to interpret the geography of a place. The conservation values expressed by residents through the public outreach and stakeholder engagement process informed the development of GIS maps. These maps, in turn, served as the basis for the online mapping tool that enables users to generate land conservation opportunity maps for the island.

In moving from the public outreach phase of the Greenprint to the Geographic Information System (GIS) mapping and modeling phase, a Technical Advisory Team (TAT) of local mapping experts provided strategic advice on data collection and data modeling. The TAT was responsible for making recommendations related to data. Their advice was invaluable in developing the criteria for each goal; identifying the best available data and their sources; and advising through the modeling process to ensure that that modeling assumptions were based on defensible science and that input data and model results were accurate.

The Greenprint Maps

A set of seven conservation values emerged from the public outreach process. The TAT analyzed public input from surveys, Island Leadership Team guidance, and SpeakOut information to inform the development of a set of color coded maps of Olahu that incorporate those land and water conservation values. By showcasing lands most in need of protection, these maps will allow organizations and agencies to coordinate planning and pursue projects where investments of limited dollars can yield the highest possible conservation impact. Today, 51,749 acres of land, nearly 18% of the study area, are already conserved. These lands include beach parks, botanical gardens, community parks, district parks, regional cultural areas, beach access walkways, steep slope areas, and state parks. Nearly a quarter of the study area—34,970 acres—is protected as a National Marine Sanctuary. Also, 51,501 acres (17.64% of the study area) are considered developed, whereas 10,157 acres are agricultural (Homer et al. 2015).

There is one map for each of the Greenprint values. These values are as follows: Protect Agricultural Lands, Preserve Cultural and Historic Places, Protect Coastal Regions, Protect Natural Habitats, Increase Recreation and Public Access Opportunities, Preserve and Enhance Viewplanes, and Protect Water Quality and Quantity.

While The Trust for Public Land and the Office of Hawaiian Affairs strive to provide the best data available, we depend on sources outside of our organizations for much of our information. We also acknowledge that there are likely data gaps in the mapped conservation values due to undocumented cultural sites, native natural habitat and other resources. Thus, there may be very special and significant places not yet reflected in the maps. Our maps are meant to provide information that can encourage various conservation efforts. The Trust for Public Land and the Office of Hawaiian Affairs are not responsible for any errors, omissions, or positional accuracy. This map is provided without warranties, expressed or implied, and will be updated and corrected over time as new data becomes available.

In the tables that follow (Tables 10.1 and 10.2), “study area” encompasses the 292,017 acres of land and 148,870 off-shore acres in the 0‘ahu Greenprint. These numbers were then combined with data derived from the North Shore Greenprint to get information for the whole island of 0‘ahu.

The seven maps describe the values as follows (in no particular order):
