RE. Risk inspection for steam vent property
Emily,
On 5/14/09 at the request of Roxanne Hampton, of your office, I viewed the above
property with Roxanne and Sativa Sultan for risk assessment. Also present was Daryl
Inaba and Mark Gushiken with COH Land Management Division. Permission had been
granted by the owner, John Gray (seller), who currently lives in Florida. Debbie Hecht
was also present for the viewing.
When we arrived at the site there were several cars parked on the side of the road
apparently belonging to visitors of the steam vents. (We did encounter several visitors
during our visit). Sativa indicated it is not unusual for there to be multiple vehicles
parked along the road by those visiting the steam vents. There is a widened shoulder
which can accommodate some parking (7-8 vehicles) without cleating any
parking/traffic issues. We walked and viewed the two lots (approx. 15 acres), one of
which is a road remnant (approx. 3 acres). There was not a survey available nor were
there any stakes or pins to identify lot boundaries, but Roxanne had a general
understanding of the property limits.
During the viewing we observed several large (5x7, 7x12, opening/depth) and many
smaller vents and had the opportunity to climb into the vented areas (access to some
vents would be limited depending on size of person). There was no disturbing smell
associated with the steam at any of the vent locations and the steam itself had a
moisturizing feeling on your skin. According to your staff, the steam is caused from
combination of lava and aquifer. An aquifer is an underground layer of water-bearing
permeable rock or unconsolidated materials (gravel, sand, silt, or clay). According to V
Comm. No. o • u

i rowel', comity a an equal opporfunrry ptor)oer and employer. Ref. UOIe JUN 0 Zang
Sativa, eruption occurred in 1955 creating the lava presence. Location of the vents are
not easily determined due to terrain and vegetation but can be accessed by paths.
These paths can be considered a risk as the terrain is rocky, uneven and steep in
places. Some of the larger vent;i are difficult to enter, ie. climbing through a small hole
into a teepee like setting while another it is necessary to climb down a steep makeshift
ladder. In its current state, due to rough terrain and some open holes at the top of steep
vents, it would not be recommended for night viewing or at anytime for a physically
challenged individual.
According to your staff, during rainy periods more steam is created and there does not
appear to be any ponding or water settlement that would create an issue, other than
slick surfaces hiking to the vents.
Information indicates the owner is interested in selling the two lots together as there are
vents on each lot. Roxanne indicated the seller may consider consolidating the lots and
then subdividing to allow all vents to be within the lot purchased thus avoiding the
acquisition of property that did not include vents thereon. I would recommend survey be
performed addressing. locations of vents and lot lines before making any decisions and
would defer to Property Management for those considerations.
Environmental assessment is recommended and I understand is being scheduled to
address among other things, soil, air quality and sanitation issues.
Since this location may have volcano/lava implications, I recommend Hawaii Volcano
Observatory be contacted to evaluate previous and future considerations.
I would also recommend hydro geologist opinion concerning aquifer status and future
expectations regarding same. It may also be necessary to have an engineer evaluate
the strength of the caves so as to absorb earthquake impacts as there are benches
located within several vent caves.
Information was not available concerning prior incidents at the site and therefore I would
suggest obtaining this information from Police and Fire.
The steam vents are a natural phenomenon that is visited regularly by tourists and
locals alike. I understand, if purehased, the plan is to maintain the area in its current
condition. This of course will create obligations of the County to include but not be
limited to signage (recommendation of shoes and water, enter at own risk, no entry at
night, etc.), security, management and maintenance.
Appraisal is also being scheduled and is vital portion of this process as if the appraised
value is less than seller will accept, all other matters may be moot.
I would recommend that Corp Counsel review the liability issue to the County
considering for both improved and unimproved conditions.
