Lake Hills and NW Lake Sammamish Sewer Upgrade Project
King County is upgrading and updating the regional sewer
service in Redmond. The sewer line starts south of NE 24th
St. at the Bellevue/Redmond boundary, and runs north through
neighborhoods to Idylwood Beach Park, where it then follows
under and/or adjacent to West Lake Sammamish Parkway all
along Marymoor Park, and then follows the Sammamish River
Trail to NE 85th St. Sewage goes north to the
Brightwater treatment facility in Woodinville. It is a
gravity line, so the alignment needs to stay pretty much
where it is. The old lines were built in the 50s 70s,
with the oldest having well exceeded their design lifetime,
and the newer sections needing repairs. Need to
replace old sewer and increase capacity 4.5 miles from
southwest of Idlewood up to Redmond City Hall.
They are doing community outreach and smaller, localized
meetings to keep residents apprised of the project.
Schedule: Design and permitting 2016-2018,
with construction to take aroud 3 years starting mid-18.
Timing of construction past Marymoor still TBD.
Initial Phase: Upcoming field work
beginning May 2016
Surveying, utility locations, (July-August) geotechnical
evaluations soils and groundwater. Small rubber-tracked
boring rig, accompanied by Bobcat. Borings themselves would
be off to the side of the trail. Drilling cores 15-30 feet
deep, putting in groundwater monitoring wells. Equipment
will move along the trail, but work and overnight storage
will be off-trail.
Construction: Will use open-trench
construction, working in stages. Some sections south of
Marymoor will be in-roadway work. Along Marymoor, and north
to the City Hall, the pipe follows or underlies the trail.
In spots they will use trenchless construction current
thoughts are to use trenchless under the roadway at the
Marymoor Way crossing.
Construction will take place typically from 7 a.m.-5
p.m., but they can sometimes get permits to work later.
Discussion: Norah will want to know about
trail closures well in advance. Many Fun Runs, etc.,
have annual events that start/end at Marymoor and use the
trails to the north. Trail events will be affected.
Jennifer indicated that if trail detours onto WLSP are
necessary, that will require permitting early in the
Norah stressed that during the summer, lane closures on
WLSP and on Marymoor Way would be VERY problematic, i.e. for
The project team is aware of cultural resource issues.
Most of the alignment will be in existing disturbed soils,
but they will be doing surveys, etc. as required.
Michael offered to put informational links onto the
Friends of Marymoor Park website, directing people to the
3) International Drone Day: May 7
Worldwide day of events about drones
technical/scientific usage, racing, recreation. Promotes
drones, but with a heavy emphasis on rules and regulations.
VERY recent FAA ruling requires all owners of drones and
model aircraft weighing over 0.5 lbs to register with the
FAA and to tag all aircraft with identifying codes.
2016 event planned at Marymoor to be located in the
McNair field (parking in Lot B). As Marymoor is already a
place where people bring their drones, this is a great
opportunity to explain Marymoor Park rules covering drones.
(Only allowed at the R/C field, and only by MAR/C members)
Free event, with classes, races, demonstrations.
Norah does not want to have this as an annual event at
4) CIP/Project/Facilities Updates:
a) Birdloop With permanent solutions for
replacing the pavement between the East Footbridge and the
eastern end of the boardwalk not possible in the 2018 time
frame, theres concern about safety of the crumbling
asphalt. We discussed with Andy the possibility of
removing the worst of the pavement and replacing with gravel
as a stop-gap.
b) Noxious weeds - Weed crew completed the spring
2016 treatment of the Canada Thistle around the bird loop.
Troy was happy to see a great reduction in the middle of the
meadow, thought they still have a challenge in the south
end. After nesting season, Troy will check back in
with Eastside Audubon and work with available staff to do a
walk through with shovels and conduct a manual removal about
the same time the thistle is blooming. Troy also told
Glenn they would treat the blackberries on Snag Row and plan
to finish that up quickly, and also touch up the poison
hemlock control for the spring.
c) Community Gardens Irrigation project
complete. Path project will hold off until after the main
d) Park Drainage asking for larger culverts for
the entrance to Lot K. Existing ones small, often get
clogged. Water backs up into Lot K, damaging pavement
Funding request for 2017-18
e) Clise Mansion wood sill restoration work,
painting done on Clise. Fixed some wall water damage.
Still working on some damaged windows (age) and some minor
f) Concert Venue Seating Concrete walkway work
starts Monday. New seating pad will be installed in
g) Shop yard fencing - Fencing approved but not
Marymoor Concerts: AEG Live will host a
Community Meet-n-Greet, Thursday May 26th Will highlight
this summer's concert series. There will be food,
beverages, and giveaways. This is an opportunity to
find out about the shows, ask questions, raise concerns.
