We had originally planned to hold a Community Meeting the evening of December 17, but we are cancelling this meeting. Attendance has been very low and, with the holidays rapidly approaching, we anticipate low attendance this quarter as well.
Please stay tuned to this blog -- and your e-mail inbox -- as we try to coordinate a time to present Euclid Creek Tunnel updates in conjunction with other local meetings already scheduled. We will let you know when the rescheduled date is.
Construction of new sewers will impact eastbound and westbound traffic on Lake Shore Blvd. near Triangle Park.
Vehicular traffic along Lake Shore Boulevard will be restricted to one lane in each direction beginning today, Nov. 19, 2013. This lane closure will occur between the Louis Stokes Bridge (immediately east of East 174 St. near Triangle Park) and Marcella Rd. This closure is for construction of the Northeast Ohio Regional Sewer District’s Lake Shore Boulevard Relief Sewer, a new sewer designed to reduce basement and street flooding in the area.
Construction is expected to continue for approximately one year. See map.
As part of the sewer project, construction crews will be excavating a large access shaft within Lake Shore Blvd. This access shaft will be used to connect the new relief sewer to the Euclid Creek Tunnel beneath Triangle Park near East 174 St.
Prior to the closure, the Sewer District re-paved the two southernmost lanes of Lake Shore Blvd. in anticipation of increased traffic flows to that portion of the road.
Blasting for the Euclid Creek Tunnel project at Shaft 2 (Easterly Wastewater Treatment Plant near E. 140 St. and Lakeshore Blvd.) and Shaft 2 (Beulah Park near E. 156 St. and Lakeshore Blvd.) is complete.
The last blasts for Shafts 2 and 3 occurred on Nov. 4, 2013, and Oct. 31, 2013, respectively.
E. 156 St. will remain closed north of Lakeshore Blvd. for continued sewer infrastructure work related to this project.
Thank you for your continued patience during this project. Have a wonderful weekend.
On Thursday, November 7, St. Clair Ave. between East 185 St. and Neff Rd. was re-opened to traffic. The street has been re-paved and was re-opened ahead of schedule. Motorists should still use caution, however, until the lane lines are added; this should occur in the next several days, weather permitting.
Euclid Creek Tunnel As you know, the Euclid Creek Tunnel is currently being constructed as a part of Project Clean Lake, the Sewer District's long-term program to drastically reduce the amount of raw sewage entering local waterways during heavy rains.
The tunnel itself (nearly 18,000 feet long) is complete, but the Sewer District continues to work on each of the five access shafts and numerous other surface-level project requirements. The Euclid Creek Tunnel is on schedule for a Spring 2015 completion.
In related news, the Sewer District has completed road repairs along Lakeshore Boulevard between East 150th Street (near St. Jerome's Church) and the Collinwood Recreation Center. The resurfacing project currently taking place along other portions of Lakeshore Boulevard is being completed by the City of Cleveland.
Lastly, all blasting near ECT-3 (Shaft 3 near Beulah Park) is expected to be complete this week.
What's New? Parts of a second Sewer District project, the Lakeshore Boulevard Relief Sewer, will begin in late October; work will be done by the Sewer District's Euclid Creek Tunnel contractor, McNally/Kiewit ECT JV. This second project will include construction of a new sewer beneath Lakeshore Boulevard near the Euclid Creek Pump Station (near Triangle Park).
This new sewer will be built using trenchless sewer construction and portions of the work will occur beneath Lakeshore Boulevard. Trenchless construction is optimal because crews do not need to dig a trench the length of the sewer to allow for installation. However, this does not mean that no surface-level work will be done. In addition to sewer construction, this project includes utility relocation and excavation of an access shaft.
During utility relocation, service will be maintained except for a brief period when the new connection is being made. The contractor is required to give all affected parties 24-hour notice before a temporary disconnection is made.
There will be traffic impacts during construction. Signage will be posted but please be aware of changing traffic patterns while utility relocation is taking place. In addition, excavation of an access shaft will occur within Lakeshore Boulevard; during this time, the northernmost two lanes of Lakeshore Boulevard will be closed for approximately eight months. However, traffic will be maintained in both directions throughout this period.
As always, thank you for your patience and understanding during construction. Please know that we will make every effort to mitigate the impacts to your neighborhood as we strive forward to improve the quality of Lake Erie and surrounding waterways.
Our next Euclid Creek Tunnel Community Meeting is Tuesday, Sept. 10, 2013, at 6:00 p.m. We will meet in the usual location, at the Memorial-Nottingham Branch of the Cleveland Public Library. The library address is 17109 Lakeshore Boulevard in Cleveland.
If you have any questions, please contact Jenn Elting at (216) 881-6600.
On Tuesday, July 23, Doug Gabriel from the Northeast Ohio Regional Sewer District presented to the Collinwood Nottingham Development Corporation. This meeting was to explain certain aspects of the Euclid Creek Tunnel and inform area business owners that a portion of St. Clair Avenue will be closing to through traffic.
On Tuesday, August 13, St. Clair Avenue will be closed between East 185 Street and Neff Road so that the Sewer District can install a structure (ECT-5.5) beneath St. Clair Avenue immediately east of East 185 Street. The Sewer District will have crews on site working 24x7, but through traffic will be restricted for approximately three months.
During this time, ACCESS TO ALL BUSINESS BETWEEN EAST 185 STREET AND NEFF ROAD WILL BE MAINTAINED. LOCAL TRAFFIC accessing these businesses will be able to travel westbound on St. Clair Avenue and travel through the signage posted at Neff Road. All eastbound traffic
will have to follow posted detours.
Detour signs will be clearly posted and the Sewer District has committed to additional signage stating that local businesses remain open during construction.
East 156th will be closing on July 15th, 2013 for 450 days (reopening approximately Oct 8th, 2014) immediately in front of our site 3-2 location (the fenced in area by Walgreen). The detour will be similar to what was utilized for the past temporary closure where traffic was directed through the parking lot of apartment complex to the east.
The next Euclid Creek Tunnel Community Meeting is scheduled for Tuesday, September 10, at 6:00 p.m. As usual, we will hold this meeting at the Memorial-Nottingham Branch of the Cleveland Public Library.
During this meeting, we will include an overview of the project as well as site-specific updates for each of our five access shafts. This project update will also include surface-level construction projects that impact vehicular and pedestrian traffic.
Just a quick reminder that we have our regularly-scheduled Euclid Creek Tunnel Community Meeting planned for tonight, June 18th. As usual, we will be at the Memorial-Nottingham Branch of the Cleveland Public Library at 6 p.m. In case you need it, the address is 17109 Lakeshore Boulevard.
Can't make it to the meeting? A copy of the presentation will be posted to this blog in the next day or two.
Blasting will commence at shaft 2-1 middle of next week and the first blast has occurred at shaft 3-1 earlier this week. This first blast went off without incident (the readings were well within allowable limits) and the contractor was pleased with results in the shaft itself. We were fortunate enough to have some of the residents standing next to us during the blast at 3-1 and were impressed with the lack of vibration from the event. That is the result of a well designed blast.
As of 6/6/13 all interior surveys of those residents in the vicinity of the 3-1 work area that have requested basement inspections have been completed. Blasting related activities have started at Shaft 3-1 and will continue through the end of July. Please refer to the previous post for details on the actual blasting procedure.
many questions that arise when someone hears that “blasting” will occur near
their property. They may include:
something we should be scared of?
Why does the
contractor need to blast?
house be shaking continuously for weeks?
before, during and after the blast?
We want provide answers to these questions below
but, first and foremost, we need you to know that blasting is safe.
this something we should be scared of?No.
One way to lessen fears is by understanding the process.
ground where the Euclid Creek Tunnel is being constructed is comprised of
overburden (typically soil or, in our case clay) and bedrock. If you were
digging in your garden, you might use a small shovel to remove a small area. For our shafts, we use hydraulic machinery
because the volume of overburden we need to remove is much greater. Regardless of the technique, overburden is very easy to excavate, but
bedrock is a different story, and it leads to the second question:
does the contractor need to blast? Bedrock,
compared to overburden, is much harder to remove for obvious reasons: it is solid
excavation of the bedrock is aided by controlled blasting inside a series of precisely spaced holes drilled
into the rock. In addition to the drill
holes, there are many other factors that an experienced explosives expert must
consider when planning each blast, including the amount of charge (explosive) and time
delay between when one charge goes off compared to the next one (nanoseconds). Rest assured, the old movies where a guy in
overalls lights a stick of dynamite, throws
it in a hole and yells, “Fire in the hole!”
are truly fiction are nowhere close to what actually happens.
not entirely true. We do yell, "Fire in the hole" as you'll read
later. And we may wear overalls.
my house be shaking for weeks?No.
You will hear the blasts, and it is likely that you will feel them, but
monitoring equipment will ensure they are maintained far below maximum
allowable limits. Here's how.
blast goes off, more than 90 percent of
the energy is used to break up the rock. The remaining energy travels through the
ground and air as vibrations and noise.
Think of the vibrations traveling through the bedrock and overburden as
the ripples in a pond from dropping a pebble into the water. The most apparent
difference is that the vibrations from blasts cannot be seen; they can only be detected with high-tech equipment. But they likely
will be felt.
Just as the ripple in a pond lessens the further away from where the
pebble is dropped, so does the vibrations from the blast. The noise from the blast can be more alarming
than the actual vibrations themselves.
vibrations and noise are accurately measured with a series of seismographs placed
around the blast site. These
seismographs are placed, maintained and read by an independent third party, not
the contractor or the Sewer District.
These seismographs record the peak particle velocity from each blast
event. Various federal, state and local
municipalities and/or agencies have maximum allowable peak particle velocity
for blasting; these standards have been thoroughly tested and are determined to
be safe for nearby structures and utilities.
The Sewer District takes the federal
government’s maximum allowable peak particle velocity and cuts this level in
half, and this becomes the new maximum allowable value for our projects. After each blast event, the data on the
seismograph are read to ensure that these maximum
values were not reached. All Sewer District blasts will not exceed
50 percent of federal standards.
individual’s response to a blast event is different. Someone busy doing housework or cutting the
grass will likely perceive much lower vibrations than someone else sitting at
the kitchen table with a cup of coffee.
People can sense very low levels of vibrations (just think of the
garbage truck picking up the trash), much lower than what would do damage to a
structure. Walking through a house,
closing windows, slamming the door or children running throughout a home will
stress individual building components more than a blast that is below the
maximum peak particle velocity.
that are accompanied by a noise will appear to be stronger than the same
vibration without the noise. Your senses
work together to give the body an impression for a certain experience; try
tasting your food while holding your nose, and again without, and the taste
will be very different.
happens before, during and after the blast? The blasting process
is extremely regulated, standardized for safety, and remains consistent each
and every time. Here’s what you can
There are strict
protocols used when handling the explosive material and in the blasting

District has used these techniques for decades both in residential and
non-residential areas and all of our contractors are experts in their fields.
seismographs are placed strategically around the construction site to record
the peak particle velocity for the neighboring buildings and utilities.
materials are placed above the bedrock to reduce noise while steel plates are
placed above and ensure the loose rock is contained.
blasting process is monitored by police; access to the roads and walks will be
temporarily interrupted five minutes before the blast and not re-started until
the entire site is given an all-clear.
At a typical
shaft site, the Sewer District will carry out two blasts per week (the blast
itself lasting less than 15 seconds each); each blast helps break up to eight
feet of bedrock. That rock must then be removed before preparation for another
blast can occur. This process is repeated until the final depth required is
East 156th will temporary be reopened early next week. The work installing the solider piles (vertical steel beams used to support the ground while the ground is being excavated) and placing dewatering pipes below grade is complete. The portion of the street that was disturbed for the above will be filled with 304 limestone (small diameter stone). Please use caution while traveling over this area. The road will be closed of approximately 15 months starting mid to late July at which time the detour that was previously utilized will be in effect.
The weather was so warm yesterday that the Memorial-Nottingham Library was forced to close due to a malfunctioning air conditioner. A closed library required a last-minute cancellation of our regular ECT Community Meeting, but mark your calendars for June 18th when we should be back to our regular schedule.
The Northeast Ohio Regional Sewer District will host our Euclid Creek
Tunnel Community Meeting tonight, May 21. The meeting, regularly
scheduled for the third Tuesday of each month, begins at 6:00 p.m. and
is held at the Memorial-Nottingham Branch of the Cleveland Public
Library (17109 Lake Shore Blvd.).
For those interested in updates, but unable to attend the meeting, a
copy of the PowerPoint presentation will be posted to the blog within
the next several days.
Thank you to those who attended the Sewer District's community meeting on May 16.
The Lakeshore Boulevard Relief Sewer includes construction of a new sewer between Triangle Park and Rosecliff Avenue. This sewer will further reduce combined sewer overflows as well as reduce basement flooding in the area.
The complete project will begin construction later this year, but a portion of the project is being incorporated into the current Euclid Creek Tunnel construction.
This portion of the project will primarily impact those living and working near Euclid Creek Tunnel Shaft 4 (Triangle Park) and includes a new sewer between Triangle Park and the Euclid Creek Pump Station. The sewer will be constructed beneath Lakeshore Boulevard, but a 70 foot deep access shaft will be constructed in the two westbound lanes of Lakeshore Boulevard. Traffic will be restricted to one lane in each direction.
If you were unable to attend the meeting and would like to review the presented PowerPoint, please see below. If you have questions concerning the project, please feel free to direct those to Jenn at email@example.com.
Work will commence in E 156th St requiring the closure of the road near the entrance to the 3-2 work area (fenced in work site). All residents affected by this temporary closure ( ~3 weeks) should have received a notice regarding the closure and detour. The detour for individuals requiring access to areas north of the closure is via E 159th and through the apartment complex.
Many Americans take the train or ride an elevator to work. These, however, are a bit more unconventional.
WKYC's Chris Tye visited our Euclid Creek Tunnel shaft site at Nine Mile Creek last week, and Bob Auber, Doug Gabriel, and Kellie Rotunno took him on a journey few people ever get to make as he visited our tunnel boring machine at work hundreds of feet underground.
The Euclid Creek Tunnel is an 18,000-foot-long 24-foot-wide sewer tunnel being constructed 200 feet under Cleveland. This is just one of several huge projects that are part of the Northeast Ohio Regional Sewer District's 25-year Project Clean Lake program intended to reduce pollution in Lake Erie.
Northeast Ohio Regional Sewer District
Traffic along E156th north of Lakeshore will be reduced to a single lane this week. This will allow for installation of dewatering wells around what will be the location of Structure 3-4 to be constructed in the future. One lane of traffic will be maintained to allow for vehicular traffic to pass at all times. Please observe the any traffic flaggers in the area.
There will be construction activity later this week or early next week in E 156th St near the entrance to the 3-2 fenced in area. One lane of traffic will be closed to allow for the work activities, flaggers will be present ensuring the smooth flow of traffic in each direction. This work includes the drilling of the dewatering wells that will be utilized in the future excavation of the Structure 3-4. Once the drilling is complete all lanes will be reopened until the actual excavation begins (July). The equipment to be used is currently working inside the fenced in area on the North side.
The Sewer District’s tunnel boring machine, Mackenzie, is working her way through the tunnel and is currently beneath Lake Erie.
If you were to visualize the Euclid Creek Tunnel as a really long cylinder – which it essentially is – that cylinder’s volume is more than 375,000 cubic yards (13.5’ radius squared * pi * 17,750’ long / 27).
What happens to all of the bedrock, or “spoils,” that is being excavated from the tunnel?
This rock travels via conveyor belt through the entire distance of the tunnel and is brought up to the surface at our Nine Mile Construction Site (Shaft #1).
Don’t worry… the Sewer District isn’t permanently creating a mountain next to I-90. The spoils are hauled away by one of McNally/Kiewit’s subcontractors to another community in Northeast Ohio that was in need of “fill.”
For years, the City of Garfield Heights has wanted to extend Transportation Boulevard farther south, connecting it to Rockside Road. To turn these plans into reality, Garfield Heights needed rock. And lots of it. The spoils from the Euclid Creek Tunnel comprise part of what will be needed to establish the Transportation Boulevard Extension.
There is another great photo taken by Lynn Ischay, one of The Plain Dealer’s photographers, last September.
A prior blog post incorrectly calculated the cubic yards of spoils as more than one million.
The Northeast Ohio Regional Sewer District will host our Euclid Creek Tunnel Community Meeting tonight, March 19. The meeting, regularly scheduled for the third Tuesday of each month, begins at 6:00 p.m. and is held at the Memorial-Nottingham Branch of the Cleveland Public Library (17109 Lake Shore Blvd.).
For those interested in updates, but unable to attend the meeting, a copy of the PowerPoint presentation will be posted to the blog within the next several days.
PLEASE NOTE: The date, time and/or location for our April meeting may change. Please subscribe to the Euclid Creek Newsletter or return to the Euclid Creek Blog for updates.
The secant pile drilling at site 3-1 will be coming to completion late this week or early next week. As the contractor completes this phase of the work, he will begin removing his equipment from the site. Both the blue and yellow crane and drill rig will be disassembled and trucked off site. We expect this to take the majority of next week.
Once the secant pile contractor is gone, the excavation contractor will begin to mobilize his excavators and cranes to the site. I will detail this work once we get closer to it.
There are more than 90,000 dogs in Cuyahoga County. If each dog poops twice a day, that could be more than 45 tons of doggie droppings every day! That's a lot of bacteria, and when it rains, that groundwater and surface runoff carries that bacteria to local waterways. Yuck.
Cleaning up after your dog is a simple step you can take help keep my watershed clean and waterways free of harmful bacteria.
Here at the Northeast Ohio Regional Sewer District, we take the environment seriously. Please help us keep things clean. + Take a look at our P.U.P program to see how you can do your part.

The tunnel boring machine that is digging our Euclid Creek Tunnel project—an 18,000-foot journey 200 feet under Cleveland's east side—is named Mackenzie. And in a few short weeks, the bed of Lake Erie will be 160 feet above her head.
The photo above marks the GPS-located position of the tunnel boring machine as of Monday. Moving from west to east (or left to right in the image) at a pace of 80 feet per day, Mackenzie should begin crossing under the lake bed within the next few weeks. The total length of the Euclid Creek Tunnel that will burrow beneath Lake Erie will be about 3,000 feet.
The weather has been playing havoc with the work crews at all the sites along the tunnel but work continues to march on. Our TBM, "Mackenzie", is currently 200' below the guard shack at our Easterly Plant and is steadily heading east, excavation of the shafts at sites 2 and 5 is being performed, the secant piles are being installed at site 3 along with some additional fencing work, ancillary structures are being excavated and constructed along Lakeshore and the various shaft locations and the detour at St. Clair and Nottingham has been removed.
Due to the severity of the weather today, most of the near surface work has been canceled. This includes the secant pile drilling at site 3-1 and the excavation of the two structures along Lakeshore Ave. Mackenzie, our favorite TBM, will remain in action today. At 200' below ground, the workers aren't exposed to the harsh weather that the rest of us are.
The map below shows the road resurfacing that is part of the work at the 3-1 site along with the area in E156th where Structure 3-4 will be constructed.
We noted yesterday that the
secant pile drilling has been progressing as the contractor had planned. Today, the first 2 of 32 piles were completed. Once all the piles are installed, the soil on
the interior will be excavated, then the rock will be removed and finally the
concrete lining of the structure will be placed. We will continue to keep everyone updated on
the progress of the shaft itself and the other near surface structures.
I want to take this opportunity
to give everyone a little information on what all is going on with the project.
The tunnel itself is 24’ diameter 17, 750’ in length and has a
volume of 60,100,000 gallons. So far,
about 3,600 lf of tunnel has been completed
There are a total of 5 shafts
associated with the tunnel ranging in diameters of 24’ to 60’ and 185-225’
There will be approximately 30
near surface structures, 10 of which are complete and 9 currently being worked
on. Associated with many of these
structures were utility relocations (water, electrical, cable, phone, etc.)
that required coordination with each provider, the City of Cleveland and
multiple other parties.
2,440 lf of open cut pipe
placed (where a trench is excavated in the road and pipe is placed in the
trench and backfilled).
2,110 lf of microtunnel
complete (remote controlled mini tunnel boring machine used when open cut is
not feasible due to depth, utilities soil conditions), 240 yet to be completed.
As can been seen from above,
our contractors have been hard at work and have accomplished much on the list
of activities needed to complete the job to “Keep our Great Lake Great”
The secant pile drilling has begun in earnest and the progress is coming along just as scheduled.We do understand that there have been some concerns over the noise and vibrations that may be occurring due to the activities and do understand this inconvenience.The contractor is doing all that they can to limit any disturbances, but please be aware that as with any construction activities whether on your neighbor’s home or on a project such as this, these disturbances are not outside what can be reasonably expected.
Please keep in mind the that sidewalk is still closed on the west side of East 156th Street due to the ongoing activities within the fenced in area, but the sidewalk will be replaced in the future once all the heavy construction traffic is complete.Also there may be short durations of traffic rerouting to allow for construction activities for the safety of the residents and the crews.Any interruption will be kept short as possible.
The new year is upon us and the Euclid Creek Tunnel is progressing towards its terminus. Site 3 has been quiet over the past days but the remainder of the drilling equipment was delivered yesterday. The commencement of the secant pile drilling will be tomorrow, Wednesday. The actual start of drilling will be mid-day. Trucks hauling off the drill cuttings will be intermittently coming and leaving the site; concrete trucks will be delivering material as well.
