This presentation summarizes a project to inventory public shoreline access in Hawaii. It discusses proposed legislation supporting public shoreline access, methods for data collection including collaborating with state and county agencies, examples from pilot studies and case studies on Maui and the Big Island, recommendations for moving forward and maintaining the data collection long term. The goal is to create a comprehensive database and maps of public shoreline access points and facilities to help ensure public access to beaches and shorelines.
GIS-Based Approach to Shoreline Access Mapping
- 1. Public Shoreline Access Inventory Robert O’Conner and Michael Lameier, NOAA Fisheries, Pacific Island Regional Office The information presented in this presentation was produced solely for the purpose of the HIGICC Luncheon Presentation and should not be used or reproduced for any other purpose.
- 2. Public Shoreline Access Inventory Robert O’Conner and Michael Lameier, NOAA Fisheries, Pacific Island Regional Office
- 3. Project Goal Collect comprehensive shoreline access information and make it easily available to the fishing community
- 6. Proposed Legislation House Bill 3265 House Bill 839 Senate Bill 32? Clean water, natural lands, and affordable housing fund (resolution)
- 7. HB 3265 Chapter 115, Hawaii Revised Statutes "§115- Public access to shorelines. Notwithstanding any law to the contrary, the State shall provide public access to the shoreline. To the extent practicable, the distance between each access under this section shall not exceed one-quarter mile.“
- 8. HB 839 Appropriates funds for the office of planning, coastal zone management program, to survey and map all existing public access ways to shoreline areas and nearby public parking areas.
- 9. Public Shoreline Access Inventory Project Purpose: Create list Plan for future Assess conditions Publish
- 10. Benefits There will be a digital base map of access ways from which future surveys and updates can utilize. Facilitate comparisons to historical access ways and associated facilities. Help determine need for additional access and if the ¼ (urban) and ½ mile (rural) recommendations are being met. Access data will be made easily available to the public. Help determine need for additional warning signs and facilities. Illegally blocked public access ways will be identified. More?
- 11. Methods Research existing data and methods Contact interested agencies Conduct pilot study • Collect data • Process data • Create the maps Gather input from other agencies Complete for all of City and County of Honolulu
- 12. Definitions Public rights of way: Any land by which the public has the right to travel and is used by or is intended for use by the public primarily to access a public beach, shore, park, trail, or other public recreational area. Public recreational area: Coastal recreational areas including beaches, shores, public parks, public lands, public trails, and bodies of water open to the public for recreational use. Dedicated public parking: Parking intended for use by the public for the purpose of utilizing a public right of way, recreational area or public park Non-dedicated parking: Parking not designated for use by a particular group or portion of the population. Shoreline: Highest reaches of the wash of the waves at highest high tide except during a major storm (ie hurricane).

Agency Collaboration State of Hawaii • DLNR Office of Conservation and Coastal Lands (OCCL) DAR • Division of Business and Economic Development and Tourism (DBEDT) Office of Planning Office of Coastal Zone Management (CZM) • Land Use Division • GIS Program • Land Use Commission NOAA • National Ocean Service Coastal Services Center • Office of Ocean and Coastal Resource Management (OCRM) Coastal Zone Management Program (CZM) City and County Honolulu • Department of Planning (DPP) • Department of Parks and Recreation • Department of Design and Construction County of Maui • Department of Planning
- 15. 1980 DPR Beach Atlas To identify desirable locations for beach park development and beach rights-of- way for the long- term future. To estimate land costs and approximate development costs.
- 17. Maui Case Study March 2005 Jointly funded by CZM and Maui County Contract awarded to OceanIT for an estimated $150K First Maui inventory conducted since 1986 Complete shoreline access inventory (public and private)
- 20. Big Island Case Study June 2006 by UH Hilo, Department of Geography and Environmental Studies and the Hawai’i County Planning Department. Funds provided by the Office of Planning, Department of Business, Economic Development and Tourism, State of Hawai`i. Electronic version financed through Coastal Zone Management Act of 1972 by Office of Ocean and Coastal Resource Management, NOS, NOAA, DOC, through the State of Hawaii Office of Planning Last update: November of 2006
- 21. Big Island Case Study “Intended to identify and describe public access ways to and along the shoreline of the island of Hawai`i.“
- 22. Preparing for Data Collection Create empty personal geodatabase
- 23. Preparing for Data Collection Assemble necessary base layers for data collection and import to pgb • Aerial imagery • Roads • Coastline • Existing access data points • Geodetic control points layer • Blank point/line file for data to be collected
- 24. Preparing for Data Collection GPS enable personal geodatabase Check out data to ArcPad
- 25. Preparing for Data Collection Build quickforms Transfer .apr to Trimble GeoXT GPS receiver via ActiveSync Verify complete data transfer Get out of the office and collect data!
- 26. Data Collection
- 27. Precision PDOP HDOP • 3-D accuracy • Horizontal accuracy • low value = high • Low value (high precision precision) needed • Not important for for canopy or urban horizontal position setting.
- 28. Processing Check In Data Post Process (but why?) Update fields Associate photographs www.trimble.com
- 29. Identification number TMK number Island Planning region Parcel Owner Access type (vertical, horizontal, or both) Access surface (grass, dirt, gravel, etc) Access width (in feet) Shoreline type (sand, rock, cliff, etc) Restroom, showers, picnic facilities? Trash receptacles, phone, lifeguard? Features Alternative name District Sign Condition Sign Visibility Sign Wording Facilities conditions (good, fair, poor) Other signs Dedicated Public Parking? Number of parking stalls Distance from access to shoreline? If dedicated parking is available, distance from closest stall to shoreline If dedicated parking is unavailable, distance from access entrance point to shoreline Distance to nearest adjacent access?
- 31. Pilot Study
- 34. Results Sites visited: 38 Blocked accesses found: 1 Hours in the field: 24 Disgruntled land owners encountered: 1 Disgruntled dogs encountered: 4
- 37. Bamboo Ridge
- 40. Moving Forward and Recommendations Projected time to Accessibility formula complete data Distance between collection phase-12-15 public rights-of-ways weeks, at 2 field days Distinguish between a week public and private access Record overgrown vegetation on neighboring properties
- 41. Looking to the future What happens after this project is complete? Who will keep the ball rolling? Prioritize areas? How do we serve the data? What about the rest of the state and the Pacific Territories?
