Receives Grant from Board of Water Supply
AWWA has been awarded a grant from the Board of
Water Supply to do a series of bus tours and community presentations on Ahupua`a
Foundations for Watershed Stewardship. These tours build on the successful
Foundations of the Ahupuaa , Ka Wai Nui Marsh, and Bioremediation site visits we
did several years ago but with the opportunity to expand to an island-wide
We are planning site visits to West Oahu,
Central Oahu, and Windward Oahu in addition to our homebase in East Oahu. The
tours will be longer because of the travel time but refreshments will be
provided. From October to March, there will be at least one per month. The tours
will feature cultural guides and experts in their fields as on-board narrators. For topics that
require more technology than can be accommodated on a bus, there will be
seminars. Content and schedules are being worked out and will be available soon.

Forward on Erosion Control , Vegetated Buffers, Ala Wai to Manoa Trail ,
Under our DLNR grant, AWWA moved forward on
ambitious projects, raising our expertise level way beyond stream
One of the contract items was to extend the
Ala Wai to Manoa trail, a concept born in the 1970 s but never fully
brought to fruition. The trail begins as a jogging path at the Ala Wai
Boathouse at Kapiolani and McCully. It follows the Manoa-Palolo Drainage
Canal up Laau Street and stops at Date Street.
Artistic exuberance overwhelmed practicality,
however, as landscaped berms and a community garden developed alongside
it. Forgotten was the drainage system of Ala Wai Elementary School.
Despite its low lying location, slightly higher than canal itself, the
school never flooded during heavy rains. Its old-fashioned system of
rounded culverts carried the water off the grounds to the canal. The
berms and the gardens blocked the natural grade and Ala Wai Elementary
became a swamp during the rainy season. AWWA
contracted for raised walkways on 3 sides of the school to counteract
the impact of the trail s berms.
tree shaded out the playfield for lower grades, resulting in a highly
eroded area, compacted by many little feet. During heavy rains, a mudpond developed, draining the sediment almost directly into the Ala
Wai Canal. As an erosion control project, AWWA arranged for tree
trimming, remediating the soil, re-sodding the surface, and landscaping
to improve the conditions.
The Kaimuki High School streambank has
been neglected for years but is a hidden treasure of the community.
Overgrowth of invasive plants hid a beautiful stream view, valued highly
by residents across the stream. Unfortunately, it also provided a hiding
place for drug and alcohol activities in the evening, posing a threat to
students who walked through the field after activities at the school.
contracted out the clearance of the dense streambank vegetation, leaving
enough to maintain the habitat for the ducks, the herons, the white
terns, the turtles, and the omnipresent mongoose. The cleared area
exposed the old riprap, the stone facing for the channel. Some of it
needs to be repaired to withstand storm flows. Community people passing
through during the clearing activity volunteered to help in future work
projects. We hope, with future grants, to turn the area into a mini
diseased opiuma trees were removed on the advice of the Outdoor Circle
and were replaced with monkeypods. The existing gravel path will be
paved as a meandering extension to the Ala Wai to Manoa trail for
walkers, joggers, and bikers. AWWA will be planning work days to
landscape the area with appropriate local and native species.
St. Louis Trail and Garden:
the intent was to link Manoa Stream to the Waahila Ridge trail system
and create a garden on the ridge. A trail already existed by Manoa
Stream next to Dole Street with access through the lo'i next to Hawaiian
Studies. The UH Botany Department, in conjunction with DLNR's Safe
Harbor Program, had started a native plant garden across the street at
the bottom of Waahila Ridge but had difficulty with maintenance.
teamed up with Downhill Hawaii, a mountain biking group, the UH Botany
Department, and DLNR to cut a continuous trail from the bottom of
Waahila Ridge to the first lookout. The trails now connect all the way
to Waahila State Park.
where the trail was cut had several sections of difficult passage. With o`o and muscle power, the bikers moved and chipped rocks to create a
trail standard 5-foot wide path. A hiker can now easily stroll through
the garden, onto the path, and up Waahila's lookout points without the
need for 4-limb acrobatics. This was especially important because
the hill has many homeless encampments.
fire starts during the dry season, the exit route is now safe for
quick retreats. AWWA assists with the maintenance of the garden.
