2) Willowmoor Floodplain Restoration Project: Greg
and Michael reported on the Stakeholders Advisory Committee
meeting that took place earlier in the day. Of note
were the conceptual design alternatives that were presented
to SAC members. Four proposals were presented,
the first being the obligatiory "No Construction"
alternative. All three new atlernatives utilize the
area west of the slough and north of the Rowing Club to
provide additional flow channels. All three also
reroute Tosh Creek (which flows under West Lake Samm Parkway
just north of the Rowing Club and which flows into the
Sammamish River opposite the 3rd dog swim beach south of the
weir) along a more northward course, joining the river north
of the weir.
Alternative #2 is the 2003 Preferred Alternative
plan from the previous Willowmoor project. The main
flow of the river westward at the weir in a single big arc.
At high water, flood waters would be able to take the
shortcut along the existing transition zone path as well.
Alternative #3 would be similar, adding a series of
parallel gravel channels that would allow water to seep/flow
to the northwest leading out from gravel sills on the west
bank of the river from just north of the Rowing Club to the
weir. These channels would run almost to West Lake
Sammamish Parkway, where they would flow into the rerouted
Tosh Creek. Flow in these channels would be seasonal.
Additionally, there would be ponds that would retain water
even during no-flow periods.
Alternative #4 would be the most radical. The
weir would move north and would become a dam, with flow over
the dam only during flood. The river would be rerouted
to the west just north of the Rowing Club, utilizing a "flow
control structure". The river would meander through
Marymoor West, rejoining the existing channel at what is now
the north end of the Transition Zone.
3) CIP/Project/Facility Updates:
a) BirdLoop - No news on availability or
suitability of surplus Brightwater irrigation parts and
pieces. Asphalt trail repairs Norah raised again the
question of whether to go with new asphalt or compressed
gravel. Gravel might work, but asphalt would be lower
maintenance and would be more resistant to moles.
Eastside Audubon will craft a very draft plan for the
future of the old Interpretive Trail.
b) Garden Loosestrife Control Project The
2013 report was submitted and accepted. Greg warned
that elodea and Garden Loosestrife could take over
Willowmoor project area.
c) Community Gardens - Laura could not attend
the meeting, however she sent along a note with news.
1) Bees: lots of progress and meetings.
Two new honey bee colonies will be incorporated into
the Community Garden as a bee plot. This is
viewed as a pilot project, to be reviewed in 2-3
years. The plot will technically be located
inside the Pet Memorial Garden are, just on the
other side of the fence and along the edge of Snag
2) ADA beds / Eagle Scout candidate project:
still in progress
3) Garden: Currently full, with a
waiting list. Lots of enthusiasm for a good
d) East Lake Sammamish Trail - The northern
portion of the City of Sammamish section of the trail
will be closing soon for paving. This section
abuts the already-paved Redmond portion of the trail
that runs along the east side of Marymoor Park.
e) Lot B Drainage and Restoration - major
maintenance to a retention area to the north of Lot B,
which is expected to reduce pooling of water in Lot B.
Lot B will also be regraded to limit the pool area. The
lot basically needs to totally regraded to fix the
damage caused inadvertently by Cavalia trucks. Work
will begin next week. Lanes will be reconfigured,
parking tightened, much of the lot will be closed while
grass regrows from hydroseed.
f) Clise Mansion New restroom fixtures,
plumbing, paint work is going on now. The showers will
be replaced, which will be beneficial for Green Room use
with the concerts. The kitchen redo is on hold for need
of money. Long term, Norah is looking to do windowpane
restoration; there are many windows that are leaded like
stained glass, and historic (and subject to historic
preservation rules). Norah would like the panes to
receive a treatment that adds a layer to the pane
providing both additional insulation and added strength
and durability to the window. But this is expensive.
g) Climbing Rock Playground Norah has put in
a long-term capital request for a full playground near
the climbing rock. In discussion of picnic sites at
Marymoor, Mike (whos from Australia) touted electric
barbecues that are used in parks all over Australia.
These could be lower maintenance than the charcoal
barbecues that are currently installed in the park, and
they would produce far less smoke.
Boat access to Marymoor - Jim brought up the
subject of boat access at Marymoor, raising the question
of mooring possibilities for both motor boats and
non-motorized craft such as canoes and kayaks. The
old lake platform floating dock was suitable for mooring
a boat, which allowed boaters to visit Marymoor.
But the replacement lake viewing platform is far too
small and too high off the water to allow moorage.
Canoes and kayaks can potentially land at the Rowing
Club dock, but there is no place on the east side of the
slough where they can land. This prevents someone
from kayaking to the park, since the RC dock is on the
"wrong" side of the river. Jim asked if something
could be done.
In discussion, there were a few concerns raised,
especially about anything that might encourage more use
of the slough by motorized boats. The slough is
marked as being a 5 m.p.h. No Wake zone, but some
boaters ignore that. As dogs swim across the
slough at all of the beaches, and as the SRA crew shells
use the slough heavily, there is a significant chance of
dire conflict between motor boats and dogs or people.
Another concern was that, while thousands of people
visit the park by car each day, only a very few people
would ever visit by boat, and probably the very high
cost of permitting and construction would not be
warranted by the usage levels of boat visitors.
Michael suggested that the people interested in
boating to the park might join forces with Eastside
Audubon on a boardwalk replacement that would include an
enhanced lake platform that would include motor boat
mooring capability, and a river platform that would
provide canoe/kayak mooring opportunities. This
would be big-ticket and hard-to-permit, but with the
combined user groups and political support, this might
