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.

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.â
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
Ÿ (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.

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).

21. Big Island Case Study
âIntended to identify and describe
public access ways to and along the
shoreline of the island of Hawai`i.â
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!
