Have GIS, Will Travel: Using GIS as an Interactive Decision Support Tool in Community Meetings

The Maui Planning Department is the lead planning agency for the County of Maui, Hawaii. The county is made up of four major islands: Maui, Molokai, Lanai and Kahoolawe. This presents special problems in providing accurate land information at community meetings. In 1996, the department opted for portability in developing a laptop-based GIS to support its community planning program. After many meetings and much travel over land and sea, GIS has become an integral part of the county's planning process. This paper will document the sometimes bumpy road to interactive GIS.


BACKGROUND

The County of Maui is made up of four major islands: Maui, Molokai, Lanai and Kahoolawe. The four islands are divided into nine (9) community planning regions (see Photo 1). County regulations require that public hearings on amendments to the regional community plans be held within the affected region. This presents special problems as some of the regions are only accessible by aircraft or boat.

Maui County map In 1997, the County Planning Department was midway through a comprehensive update of the regional community plans. The update included dozens of proposed amendments which affected scores of properties within each community plan region. All of these changes had to be reviewed by the appropriate planning commission and then transmitted to the Maui County Council (the County's legislative body and final authority on planning and zoning issues) for review and adoption.

During the course of the Council's review of the update of the Kihei-Makena Community Plan, it became readily apparent that the use of hard copy exhibits was adversely affecting the planning process. Whenever a complex question arose, the process would be put on hold while the department researched the issue and then transferred the findings onto an acetate overlay. The overlay would be draped over a hand-colored display map (1:24,000 scale) of the region. Delays of several weeks were commonplace.

Finally, the County Council and the Planning Director agreed that the situation had become untenable. The only solution was to develop a fully functional GIS which could be used to support the Council's deliberations on the community plans. The staff of the Office of Council Services and the Department of Planning were directed to deliver a working GIS for the Kihei-Makena region within 90 days.

THE PROJECT TEAM AND THEIR APPROACH

The project team was made up of Wayne Boteilho (Legislative Analyst within the Office of Council Services), Walle Landenberger and Bill Medeiros (Cartographic Technician and Planner, respectively, within the Planning Department). The team immediately realized that, while replacing hand-colored maps with computer-generated maps would improve quality, paper maps were not going to be the answer. What was really needed was a fully interactive GIS that could be taken out to community meetings and be able to answer questions on-the-fly. Once this goal was set, the team divided up the workload and dove in.

The initial step was developing the system specs. This turned out to be the easy part. Portability required using a laptop. Both Planning and Council Services were already using Microsoft Windows as their base operating systems. It didn't take a rocket scientist to figure out that if you needed to run GIS on a Windows laptop, you had to get ArcView.

Using ArcView to hotlink to a photo After purchasing a laptop and a copy of ArcView (version 3.0a), the Planning Department licensed digital parcel data for the Kihei region from an Oahu GIS vendor, GDSI Hawaii. Using the parcel base, Planning began to develop layers of Community Plan designations and zoning. Planning also acquired GIS data from the Hawaii Office of State Planning. However, as is commonly the case, the datasets were in different map projections. The State data had to be reprojected into the County's map projection and datum. Initially, this had to be outsourced. Later, with the help of the Esri CA/NV/HI/GU Regional Office staff, the Esri Hawaii User Group was able to figure out the answer to a particularly pesky problem involing trying to convert between Hawaiian datums. Once this was resolved, the Planning Department was able to do reprojections inhouse using ArcView.

While the Planning Department worked at acquiring and developing base layers for the GIS, Council Services contracted Royce Jones of GDSI Hawaii to provide GIS support and to digitize specific data layers requested by the County Council. These layers included historic and cultural features, wetland areas and proposed roadways. Council Services also scanned photographs taken during the Council's visits to the various sites. These scanned photos were loaded into the machine and pulled up using ArcView hotlinking tool. (See photo 2)

THE SYSTEM MAKES ITS DEBUT

In June 1997, the County Council prepared to take up the Kihei plan again. The team feverishly worked to get the data double-checked and edited. Of course, an hour before the meeting, the machine crashed and the entire project had to be rebuilt from scratch. The work continued as the meeting started and the Council went through the initial items on the agenda. Finally, the lights went down, the digital projector was switched on and the outline of the Kihei-Makena Community Plan region came up on screen.

Using ArcView to identify flood and tsunami areas The system worked flawlessly. The Planning staff explained the various data layers while Royce Jones ran the machine. Zoom in. Query the ownership of a parcel. Zoom out. Show all the proposed amendments to the community plan. Zoom in. Identify which changes are in proximity to defined wetlands. After a few questions about the system, the Council started to discuss the Kihei community plan in earnest. As the discussion began to center on the amount of vacant hotel-designated lands within the region, the staff jogged over to Royce and whispered, "Building value equals zero and CP equals 200."

On screen, the parcels started to draw up in ArcView's standard selection color. Staff leaned into the microphone and said, "The properties highlighted in yellow are vacant and designated for hotel use."

We haven't used very much clear acetate since then. And three years later, the system continues to impress. We make a concerted effort to add a little more functionality each time we start up a new project. We work diligently on developing new data as well as verifying and editing existing data. Incremental improvements, no matter how small, add up over time.

WHERE ARE WE NOW

ArcView has not changed the world as we know it. But it has made us more able to do the job that the taxpayers of Maui pay us to do. Nor does GIS guarantee better decisionmaking. But it does much to promote better informed decisions.

Since 1997, the GIS has been used in the Community Plan updates for three regions: Kihei-Makena, Lanai and Wailuku-Kahului. The Planning Department is already gearing up for the Molokai update later this year. The GIS has also been used to support major zoning projects such as the Lanai Comprehensive Zoning project which rezoned over 800 individual properties.

There has also been an interesting side benefit to our decision to use interactive GIS in meetings rather than paper maps. Participants, no matter which side of an issue they are on, feel more a part of the process when they can see the information live and can pose questions and see the results come up on screen. The GIS has also quickly resolved potential disagreements or misunderstandings and kept meetings on track and let the participants focus on the key issues.

Using GIS in community meetings GIS has become an integral part of the planning process within the County of Maui. The system has been taken on the road to community meetings and public hearings in school cafeterias, community centers and libraries throughout the county. The County has begun to utilize GIS to support community-based efforts in areas such as disaster preparedness and the identification of community-defined cultural resources. (See photo 4)

In 1999, Esri recognized the efforts of the GIS team with a Special Achievement in GIS award. This proves that a small-scale GIS can make it to the big leagues. In March of this year, the County initiated a reorganization to move the Planning Department's GIS team into the Office of the Managing Director in order to promote countywide GIS. To this date, seven County agencies, including the Department of Public Works, County Civil Defense and the Maui Police Department have begun GIS projects.

THE LESSONS WE'VE LEARNED

We have learned a lot in these last three years. We have tried share this knowledge with others in Maui and throughout the state through conferences and user group meetings. This paper gives us the opportunity to share some of what we have learned with folks outside of Hawaii. And, if there is one thing that we have learned, it is that you don't need a multi-million dollar system to create an effective GIS. A clear focus on a specific goal or issue, a little ingenuity and a lot of hard work can go a long way in reducing costs and maximizing the potential for success.

Here are our top ten keys for a successful GIS:

On that note, let me pass along a big mahalo or two to all the folks that have helped us out along the way.

ALOHA AND MAHALO

First, let me thank the rest of the project team:

Second, the folks behind the data and the software:

Next, the folks that got us into this back in 1997:

And finally, much thanks go out to you for reading this paper (or worse yet, actually sitting through my presentation). I hope some of this has proven helpful to you.

Mahalo nui loa from the Maui GIS folks...
