Application to Waitakere Community Board
for Park Development Funding at Karekare Waterfall
1. Overview
We thank you for the opportunity to apply for Park Development funding
from your discetionary fund. KKLandcare, under the umbrella of KKRRPT
is, in conjunction with other stakeholders, developing an action plan
to restore and rehabilitate the "Four Streams" area, which is
the portal for most visitor activity and traffic at Karekare. The waterfall
area appears as item D in the attached discussion document.
The Karekare waterfall is heavily visited by locals, picnickers, trampers,
wedding parties and film crews. Loss of vegetation and erosion of the
poolside and surroundings has increased markedly over the last few years,
and a significant deterioration of amenity is likely in future unless
action is undertaken to protect and restore the area. The sum of $4,500
is respectfully requested.
2. Proposal
KKLandcare and KKRRPT, assisted by ARC staff (Simon Stoddart, Ranger;
Ken Becker, Riparian Management; Ngaire Sullivan, Land Care) proposes
that the banks of the pool and stream outlet be protected by an arrangement
of rock and vegetation "islands" using large (~ 200 kg) boulders
arranged to resemble the "rock gardens" that are a feature of
the banks of the nearby Opal Pools stream. The boulders would come from
the Bethells quarry, be bought along the track to the site by rubber-tyred
mini-dozer, placed under the direction of local artists, and planted in
native species. Boulder faces would be aligned to create a "natural
stairway" down to the pool, whilst encouraging visitors to stay on
the existing path. The boulder wall would also protect the nikau palm
whose roots have been exposed by flood waters diverted by past attempts
to dam the stream outlet to increase the depth of the pool. It would also
be possible to use small stones from the bottom of the pool as fill between
the boulders, thereby going someway to restoring the pool to its original
depth. The existing picnic table, which currently "moves" all
around the area, will be relocated to the old concrete BBQ pad, and fixed
there. This, in conjunction with the new bench seat near the pool, will
provide ample amenity for visitors.
3. Resources
ARC will provide riparian and and project management expertise (the site
manager will be a local ARC Parks Ranger). Labour is available from the
Justice Dept. Periodic Detention workers who spend one day every week
at Karekare under ARC supervision, and who have assisted with previous
ARC / KKRRPT restoration projects. KK Landcare and KKRRPT will provide
artistic direction as well as "sweat equity", and will maintain
the plantings and provide overall coordination between stakeholders. Funding
is sought from Waitakere City Council, the owner of the land, via the
Waitakere Community Board. The sum sought is $4,500, which includes the
costs of rock and fill, transport, native plants, compost, contingencies
and administration.
Thankyou for your consideration,

Where Four Streams Meet:
an ARC / KK Landcare/KKRRPT / WCC discussion document
Boundaries of area under discussion
Karekare Stream: from the Watchman Rd bridge to the lagoon
Murdoch Stream: from the "twin pohutakawa" by the road
Opal Pools Stream: from the pools along the Lone Kauri Rd to the confluence
with Company Stream
Company Stream: from the waterfall pool, through Bill's park, then past
the carpark to the lagoon
Areas of concern
Karekare Stream
streambanks both sides of the Watchman Bridge constricted with slumping
and invasive weeds pampas and bamboo overgrowth stream bank undercut and
slumping, especially alongside Karekare Road, just past mailboxes roadside
verges bare earth, gouged by traffic
Murdoch Stream
moderate erosion toilet block itself
Opal Pools Stream
informal pathways people create from road to pools are eroding the steep
bank and damaging plants
Waterfall pool
severe erosion due to flooding, traffic and the partial damming of the
outlet
Company Stream
invasive weeds overwhelming native plants on the streambanks,
inadequate Carpark ARC bulletin board due for upgrade?
Remedial projects and estimated requirements
A. Karekare Stream
1) Remove pampas at Watchman Bridge, put in roadside barrier and plant
streamside natives (flax, nikau, etc) Resources: $550 plants and mulch
+ labour
2) Harvest bamboo at Watchman Bridge as close to ground as possible and
interplant with streamside natives (sheets of corrugated iron can be driven
into the ground to stop the bamboo roots from spreading. Tubes of corrugated
iron set into the bank around the young plants will also assist them)
Resources: $400 plants and corrugated iron + labour
3) Clear up the bottleneck in KK stream downstream from Watchman bridge
by removing broken trees and realigning boulders. The bottleneck is forcing
water through in such a way as to undercut the banks. A section now threatening
to undercut the road could be saved with baskets of rocks, grading and
plantings as was the Green car park streamside (this area is a good model
for such corrective measures) Resources: detailed costing required; involves
LTA, WCC?
4) Protect the stream/roadside plantings from cars being parked on them
with either rocks or low railings Resources: $300 plants + fencing + labour
5) Encourage and assist Watchman Rd locals tidy up the mailboxes and rubbish
collection area near the bridge
6) Two years ago, the green carpark was partially resurfaced by rock and
fill from an abortive attempt to develop a streamside floodplain. This
has caused erosion and drainage problems, and the carpark needs to be
regraded and returfed, with a new layer of sand over the rock to prevent
grass die-off under summer traffic.
Resources: Request to capital works budget of ARC
B. Murdoch Stream
1) Control erosion by planting the stronger natives found on the banks
further upstream. Resources: $300 plants + labour
2) Upgrade the toilets (not enlarge them, but redesign and upgrade septic
system). Shower taps could be included for bathers to wash off salt and
sand. Resources: Request to capital works budget of ARC
C. Opal Pools Stream
1) Either formalize a pathway down the steep bank or simply repair the
damage in such a way as to discourage such use or minimize damage (steps
of stone or wood? rope handrail?) Resources: Request to capital works
budget of ARC
D. Waterfall pool
1) Bring in rock slabs, boulders and plants to create a naturalistic pool
bank in some ways like the Opal Pools stream bank, which will bear foot
traffic and winter water flows without the heavy erosion happening now.
The erosion here seems to be accentuated by people shifting the rocks
to pool the water. The rock slabs need to be big enough to discourage
such landscaping efforts. Involvement of local artists could help achieve
a "wild look" to the restoration. Resources: Request to Waitakere
Community Board Park Development Fund
2) Either fasten the existing picnic table to the old concrete BBQ pad,
or remove it entirely. If the latter, a new picnic table could in future
be placed at a distance from the pool, which would take some pressure
off the immediate waterfall area, leaving it more "wild".
E. Company Stream
1) With help of local artist, redesign the bulletin boards. Resources:
Request to capital works budget of ARC 2) Plant natives among the invasive
streamside weeds to encourage a shadier waterway. Resources: $400 plants
+ labour
F. Water Pollution Monitoring programmes and procedures need to
be assessed in the light of current data. Are the results good enough?
G. Commercial Filming and Tourism
KKRRPT/KK Landcare is working to establish consultation and liasion protocols
with film and tourism companies and their controlling local authorities
(eg Waitakere Enterprise Board), to ameliorate the impact of these industries'
growing use of the Four Streams area as both a portal and a destination.
