Water Storage Projects updates and Announcements


The water storage project sites are integrated with the surrounding neighborhoods and are valued open space amenities that enhance the quality of life for residents. As such, it's important to keep the public informed and involved in project planning and construction work.

Following is a running list of updates and announcements.

E. 40th

March 1, 2024: We are several major steps closer to completing the water storage project near East 40th Avenue.  

The first tank is fully commissioned and serving drinking water to Eugene residents. The second tank is expected to be operational later this month. 

With tank construction complete, EWEB can move on to the next phases of work. 

The area around the tanks will be backfilled so that only about 12-15 feet of concrete remains visible. Backfilling started earlier this week and will take 3-6 months with increased dump truck traffic. 

The tanks will then be fenced and screened with vegetation. Later in the year, EWEB will collect community input to complete landscape restoration and enhancement of the site. 

Pipeline work is expected to continue through summer 2024 on Hilyard Street from around Tugman Park to East 33rd Avenue. The City of Eugene has plans to rebuild Hilyard Street this summer.

Jan. 9, 2024: Happy New Year! With construction of the new East 40th water storage tanks and associated piping completed in early December, our focus is now on commissioning the new tanks, which includes disinfection, leak testing, and then draining and refilling each tank. To ensure the process doesn't create water quality or service impacts across the water system, several EWEB teams are coordinating efforts including engineering, water treatment plant operators, pump and equipment specialists, and construction crews. Many thanks to these folks who worked throughout the holidays to ensure a safe and efficient process. 

Unfortunately, despite our best efforts commissioning the new tanks is taking longer than expected. EWEB crews and contractors will be onsite for the next several weeks completing the process. We do not expect significant construction noise, truck traffic, or other impacts during this phase of work. 


Once commissioning is complete, what's next?

After the tanks are fully online, the next step is backfilling so that only about 12-15 feet of concrete remains visible. The tanks will be fenced and vegetative screening will be installed. We are in the early stages of planning for this next phase of work. Our landscape architect contractor is creating a design that includes diverse native plants and drought-tolerant species. We expect to have a preliminary design ready for public input by early spring. 

Nov. 9, 2023: Crews have finished excavating for an underground concrete vault near the entrance to the tank site, and have started constructing the forms that will hold the vault's concrete floor and walls in place. Once concrete work begins, there will be approximately five pours, and each pour will be relatively small (just a few truckloads) separated by several days of curing.

Later in November, crews will begin work to install and connect the new pipes in Patterson Street to the tanks, after which the tanks will be filled with water and put into service.

Pipeline construction

In September, pipeline work began along Hilyard St. creating traffic delays and detours, including sidewalk and bike lane closures from E. 40th to E. 33rd Avenue. Please remember to drive slowly through the detours.

Important safety reminders
  • Avoid active work zones if possible.
  • When you need enter the work zone, please wait for the contractor or EWEB staff to escort you safely through. This may take a few minutes but will ensure you pass though the work area safely.
  • Make sure to check your surroundings, including overhead.
  • When heavy equipment is in use, make eye contact with the operator and wait for them to acknowledge you before entering the work zone.
  • Remember that construction equipment can move suddenly and quickly.
  • Don't linger. Get through quickly and watch your step.

Aug. 1, 2023: Work on Patterson Street to install the new water transmission main is progressing, but slowly. There are two main reasons why work is taking longer than anticipated:

Collapsing trenches: Contractors have discovered that when the sewer lines were installed beneath Patterson Street, pea gravel was used as backfill. Pea gravel is round and doesn’t compact well. As the contractors are excavating for the new pipeline, the pea gravel is spilling into the newly excavated trenches and undermining the road. For each section of pipe, the contractor must shore-up the trench and backfill the void under the street.

Hard rock: The contractors are hitting hard rock just a few feet beneath the surface, which is slowing down excavation and requiring the use of a rock-breaking hammer.

As a result of ground conditions, contractors expect it will take another 2-3 weeks to complete the transmission pipeline work on the west side of Patterson.

Contractors are making every effort to expedite the work, including working past 5 p.m. to finish up critical tasks or restore driveway access. For the next few weeks, noisy work may continue as late as 7 p.m., and workers may be on-site past 7 p.m. performing clean-up activities.

We understand that this phase of the project is very disruptive, and we appreciate the continued patience and understanding of area neighbors, especially those on Patterson Street.

After the transmission pipeline is installed, the next phase of work will be performed by EWEB crews, who will connect Patterson Street water service lines to the new pipe. Connecting the service lines will be much quieter work, and less impactful to access in and out.

Once Patterson Street residents are connected to the new pipeline, contractors will return to install the drain line for the tank, along the east side of Patterson Street. That will involve several more weeks of street work very similar to the current work, with elevated noise levels and access impacts.

All told, we anticipate the transmission and drain pipe work on Patterson Street and the intersection of Patterson and E. 40th will continue into September.

Road closures and detours

East 40th Vehicle traffic is being detoured along E. 39th Place for several weeks.

July 19, 2023: Construction of the 36-inch pipeline that will connect the new E. 40th water storage tanks to the water system is fully underway. We want to acknowledge this phase of work brings with it additional impacts to the neighborhood, and we appreciate your patience and understanding. 

The pipeline work on Patterson Street and E. 40th will continue through August and potentially into early September. In September, work will begin on Hilyard Street.

What to expect during this phase of work:

Pipeline construction will create noise, traffic, vibration, dust, and disrupt normal neighborhood activity.

There's no way around it -- street work is loud and disruptive. Crews must remove the existing roadway and dig deep into the ground to access existing utilities and install new infrastructure. Beneath the road surface is a vast network of public and private utilities. Similar to remodeling an old house, you never know what you'll find and unexpected problems will arise.

We know neighbors of this project have already been through a long construction process, and this phase of work is, in some ways, even more unpleasant and difficult. EWEB and our contractors will do our best to minimize noise, delays, and other problems. And when something does go wrong, we will do our best to fix the problem as quickly and safely as possible.

Residents may experience intermittent water service disruptions.

This is necessary to move customers and fire hydrants to new pipelines and to abandon the old pipelines. EWEB will provide at least 24 hours notice before turning off your water. In most cases, water service connections can be performed 4-8 hours, but unexpected problems can arise and prolong the service interruption. We encourage you to store three days of water for emergency use.

Unplanned outages may also occur as contractors dig around and expose old utilities. Some of the infrastructure underground is decades old and easily damaged. If this occurs, EWEB and our contractors will notify you right away do everything we can to restore service quickly.

Access to driveways may be restricted during work hours.

Contractors will do their best to provide access upon request but due to the nature of the work, access cannot be guaranteed at all times. Contractors have been directed to restore access to properties outside of work hours whenever feasible.

In addition, EWEB has requested that workers carpool or park elsewhere to leave sufficient space along nearby streets for residents to use as parking if you choose.

There may be changes to mail and trash service routines.

The contractor will work with service providers to accommodate pick-ups and deliveries whenever possible. We have learned that the USPS has notified some neighbors that mail delivery was not possible on a given day and to pick up mail at the post office.

Sections of roads will be temporarily closed and traffic will be detoured.

The contractor will place road closure and detour signs. Access will be maintained for pedestrians and bikes, with the exception of unplanned events that may cause temporary disruptions.

Work will typically begin at 7 a.m. and conclude by 5 p.m., Monday through Friday.

In order to complete the work as quickly and efficiently as possible, some construction activity may last past 5:00. Efforts will be made to limit noise and allow traffic through after 5 p.m.

Contractors may need to leave tools, machines, and supplies on the street overnight.

For safety, please stay away from them.

 

Map of Patterson St pipeline work

April 7, 2023: Notice of Saturday Work

We learned this evening that the detention pond at the project site has apparently been vandalized, causing minor flooding in a neighbor's property and on Patterson St. EWEB staff notified the contractor who returned to the site and implemented a temporary fix. The contractor will be back tomorrow (Saturday) with a small excavator to install a new pipe and repair the damaged equipment. Work will take place from approximately 11 a.m. to 4 p.m. and will create some noise. This is not the first time the site has been vandalized. We are working with EWEB Security and Eugene Police to investigate.

March 29, 2023

Construction crews are preparing to start the next major phase of work: wire-wrapping the tanks and covering them in shotcrete. Please see important safety reminder below.

Wire-wrapping the tanks is required for earthquake resiliency. The cables are high strength, galvanized 7-strand wire that bonds to multiple layers of shotcrete (sprayed-on concrete). More than 90 miles of wire will be applied to the two tanks!

This process ensures the structures can contain the large loads produced by the stored water as well as the strength and durability to undergo horizontal and vertical ground movement during an earthquake.

For safety, the entire site will be closed during this stage of work.

Additional fencing has been installed to allow an additional 100 feet of clearance around the tanks. On the east side of the site, additional trailers will be installed to provide the necessary safety buffer.

The cables used to wrap the tanks will be under incredible tension stress and if one were to snap, the force could be very dangerous. We ask that neighbors and all members of the public stay clear of the site during this stage of work, which is expected to last around 16 weeks.

Other news and info:

  • The final roof pour is tentatively scheduled for Thursday, March 30 (weather dependent).
  • Material that is no longer needed will be moved off-site once the last roof pour is complete; expect some minor truck traffic.
  • Prior to application of wire and shotcrete, the tanks will be pressure washed.
  • Pressure washing and applying the wire and shotcrete will create additional noise at the site.
  • The pipes that will connect the new tanks to the water system will be delivered soon and will be staged on the west side of the work area.
  • The piping work in Patterson Street will occur in June, and will create access and parking constraints. More info to come as this phase of work gets closer.

water storage tank under construction

Dec. 23, 2022

Concrete work continues, with crews continuing work on the roof of tank #1 and columns of tank #2. The project is on schedule and on budget.

What to expect

Both of the 7.5 MG tanks are being constructed concurrently, beginning with the floors, then walls and columns, and eventually roof slabs.

Concrete work
Tank #1 roof slab pours are tentatively scheduled for Dec. 29 and Dec. 30. The pump truck will arrive on site around 7 a.m. and concrete will arrive shortly after. We are anticipating each roof section will require around 45 concrete trucks. There will be increased cars parked on E. 40th on roof pour days.
 

Tree work
EWEB foresters will be on site in the next week to identify hazard trees for removal. EWEB is doing this work to protect neighboring residences and public safety on the site. Tree removal will likely occur before the end of January.
 

Ferry St. main replacement work
EWEB crews will begin a water main replacement project on Ferry Street north of 43rd Ave. The work involves replacing 500 feet of existing 1950s water infrastructure with a new 8” pipeline, new water services, and a new fire hydrant. The work is schedule to being in early January and will take approximately 2 to 3 weeks to complete. Work hours will be Monday through Thursday and will take place within the City of Eugene’s allowable work hours of 7 a.m - 7 p.m. 
 
Directly impacted neighbors will receive additional communication. If you have any questions or concerns about this work, please contact the EWEB Water Division at 541-685-7595.

Holiday work schedule
Construction crews will be off and there will be no planned work at the site Monday, Dec. 26 and Monday, Jan. 2

Dec. 9, 2022

Concrete work continues, with crews preparing to begin pouring the roof of tank #1. The project is on schedule and on budget.

What to expect

Both of the 7.5 MG tanks are being constructed concurrently, beginning with the floors, then walls and columns, and eventually roof slabs.

Roof construct to begin next week

Wall pours are almost complete, and scaffolding is installed to prepare for the first roof section pour which will be on Monday, Dec. 12.

The roof slabs will be poured in quarters, just like the floors. However, the roof pours are almost twice as big as the floors because the roof is twice as thick. To accomplish the roof pours, workers will begin arriving to the site before 7 a.m. We have asked that they keep noise to an absolute minimum as they arrive and prepare for the work day.

The pump trucks will arrive on site around 7 a.m. and concrete will arrive shortly after. We are anticipating each roof quadrant will require around 45 concrete trucks. There will be increased cars parked on E. 40th on roof pour days.

On some days, finishers and laborers may be on site until 7 p.m. We anticipate that the concrete will be placed and the pump truck will be offsite prior to 7 p.m.

Holiday work schedule

Construction crews will be off and there will be no planned work at the site Monday, Dec. 26 and Monday, Jan. 2

Thank you to KEZI's Billy Hanning for this fantastic drone footage of the project.

Nov. 10, 2022

Concrete work is well underway and will continue through late spring/early summer 2023. The project is on schedule and on budget.

What to expect

Both of the 7.5 MG tanks are being constructed concurrently, beginning with the floors, then walls and columns, and eventually roof slabs.

Concrete is being poured every day

The concrete floors of both tanks are poured and cured. The wall around the first tank is done except for the last section which will remain open for equipment access. Scaffolding is now being installed to prepare for the first roof section pour which will be in late November. At the same time, wall pours have started on the second tank.

The trucks will continue to create engine noise and a loud humming sound during this phase. Because of the cold weather the columns and the walls are being wrapped to keep the new concrete warm during the initial cure time.

Additional slope protection measures are being installed

For worker safety, a chainlink fencing is being installed over the slope to direct sliding material down to the bottom of the slope. The chain link will not be visible at the end of construction. The fence around the back is being moved further away from the slope to protect people walking so they don’t get too close to the unstable edge.

Holiday work schedule

Construction crews will be working on Veterans Day, Nov. 11. They will be off Nov. 24-25 Tor Thanksgiving. We do not yet have the December holiday work schedule, but will share that as soon as it's available.

Additional potholing work planned

Beginning Tuesday, Nov. 15 an EWEB contractor will excavate a series of small holes to locate underground utilities on Patterson and Hilyard streets. "No Parking" signs will be set-up on Patterson St. tomorrow (Nov. 11). This potholing effort is a much smaller effort than previous work conducted over the summer. No major delays are expected. There could be minor inconveniences where a driveway is blocked for a short period of time, but the contractor will work with homeowners to minimize disruptions. We anticipate the work will take approximately 3 days.

Watch a time lapse video of recent work.

Sept. 16, 2022

Concrete work is well underway and will continue through late spring/early summer 2023. The project is on schedule and on budget.

What to expect

  • Both of the 7.5 MG tanks are being constructed concurrently, beginning with the floors, then walls and columns, and eventually roof slabs.
  • The floor of the first tank is poured and cured, and the wall forms are going in while the floor of the second tank is poured. Floor pours for the second tank will start at 7 a.m. on 9/19, 9/29 and 10/12.
  • The contractor will begin pouring the walls on Sept. 20. They will use a crane to inject the concrete through "windows" in the wall frames. Pours will occur twice a week starting at 8 a.m.
  • By the end of the month, the support columns will start going in.
  • The concrete trucks and pumps will create engine noise and a loud humming sound. In between pours, while concrete is setting, it will be fairly quiet at the site.

Watch a time lapse video of work at the site since mid-July:

July 29, 2022

Earthwork and tank subgrade preparation is complete and dump truck hauling is mostly over for now. Crews are currently working on installing rebar and forms for the floor of Tank 1 in preparation for concrete. For the next year or so, it will be primarily concrete work at the site.

What to expect

Both of the 7.5 MG tanks will be constructed concurrently, beginning with the floors, then walls, then roof slabs.

The floors (and eventually roof) slabs are the largest concrete pours that will happen, meaning lots of trucks running continuously.

The floors will be constructed in quadrants and will take a total of four concrete pours for each floor slab. In total, each floor slab will require approximately 800 cubic yards of concrete.

The first major pour will occur on Friday, Aug. 5 and will require approximately 20 truckloads of concrete. Note this date may need to be shifted depending on progress and availability of concrete and the required staff.

The trucks will be safely staged near the site, starting around 6:30 a.m. on Aug. 5.

You can expect a few more construction workers on pour days and they will be arriving a little earlier than normal to be ready. Crews will arrive at the project site around 6:30-6:45 a.m.

At 7 a.m. the first truckload of concrete will arrive, and then trucks will come and go in a continuous stream about every 10 minutes through early afternoon.

After Aug. 5, the next scheduled pour dates are tentatively Monday, Aug. 15 and Thursday, Aug. 18.

Once the floors are poured, the frequency of pours will increase to several a week, but each pour will be smaller--just a couple of trucks per day.

The concrete trucks and pumps will create engine noise and a loud humming sound. In between pours, while concrete is setting, it will be fairly quiet at the site.

 
Reminders regarding general construction impacts:
 
  • We will only do work during hours that the City of Eugene noise ordinance allows and we will communicate work hours as the work progresses.
  • Truck noise such as beeping is not easily mitigated as that is an OSHA-required safety feature and needs to be loud enough for someone to hear while wearing hearing protection. When possible, trucks will be routed around the site to avoid the need to back up.
  • While we can't anticipate or mitigate all impacts, we will be responsive to your questions, suggestions, or concerns. Please reach out to us directly so that we can quickly address any issues that arise by email at water.storage@eweb.org or by phone at 541-685-7899.

Timelapse cameras capturing construction

Cameras have a special ability to help us see what the human eye can't. Infrared spectrum cameras like the Wildfire Alert camera EWEB recently helped install can detect heat from wildfires. Macro lenses and high frame rate cameras can help us zoom in to the minuscule and slow down what's too fast to detect. Timelapse cameras speed up time and let us observe changes that might be imperceptible otherwise.

Thanks to two new timelapse cameras, we can now view months of construction at the E. 40th project site in a matter of seconds. Watch the walls rise from the earth. Watch the shadow of the crane spin like a sundial. See the construction crews zip around like a team of ants.

We will share new videos every month.

June 28, 2022

Beginning the week of July 5, 2022, an EWEB contractor will excavate a series of small holes to locate underground utilities from the intersection near 34th and Hilyard St., south to the location of the water storage construction project off E. 40th and Patterson St.

This survey work is necessary to design and construct the 36” water pipe that will eventually deliver water from the new storage tanks to homes and businesses throughout Eugene. The utility location work will last about two weeks and will primarily take place Monday - Friday between 9 a.m. and 4 p.m., however intermittent work may occur outside of these hours if necessary.

What to expect

  • Construction trucks, flaggers, lane closures, and restricted street parking for this stretch of Patterson, E. 40th Ave. and Hilyard St., including along Tugman Park.
  • Loud equipment noise.
  • Possible delays for cars leaving or entering residences along the route.

Once the survey work begins, the contractor will make every effort to maintain access to the street and driveways, but residents might experience delays coming and going.

Construction of the pipeline will cause additional traffic impacts during the spring-summer of 2023.

Additional updates

  • The excavation and tank subgrade preparation stages of work are nearly complete. The large excavation equipment will leave the site within a couple of weeks.
  • The tank construction contractor (Skaar Construction, Inc.) will arrive onsite with a crane and other equipment at the end of June.
  • Expect an increase in truck traffic as deliveries of rebar and piping arrive starting the week of June 27.
  • In early July, work will begin on installing forms and rebar for the inlet/outlet piping that will be encased in concrete under the floor slab.

View project phases and timeline

May 4, 2022

Tank construction expected to begin this month.

At the April 5 public meeting, EWEB’s Board of Commissioners awarded the contract for tank construction to Pacific Excavation (Pac Ex). Pac Ex was the lowest responsive bidder and is the same company that EWEB contracted to provide tree removal and excavation services at the site.

The first phase of construction—laying the subgrade and constructing the drain system—is expected to begin in the next couple of weeks. We anticipate concrete work to begin late-May to early-June 2022 and last approximately a year.

Preliminary site restoration activities planned.

EWEB staff have started working with a contractor to scope out fire mitigation improvements. The ecological study conducted in 2021 identified several potential improvements to reduce fire hazards, enhance habitat value and improve the overall health of the site.

In the coming months, you can expect to hear more information about fire mitigation and other site improvement plans. In the short-term, EWEB will be working with a local contractor to mitigate poison oak on the West side of the property.

Pipe design work is underway.

EWEB is starting preliminary design work for the new 36-inch water transmission main that will be constructed between West Amazon St. and the intersection of East 40th Ave. and Patterson St. We anticipate that that phase of the work will go out to bid late summer to early fall, with construction occurring mid-to-late 2023 after the concrete work on the tanks is complete.

New bench installed.

A new bench was recently installed on the east side of the property to replace the bench that was destroyed by vandals.

WHAT TO EXPECT AT THE SITE 

  • Truck traffic and construction noise will resume in the next couple of weeks as crews begin laying the subgrade and constructing the drain system.
  • Work hours will be Monday – Friday starting at 7 a.m. and ending by 5 p.m.
  • Workers will be removing blackberries on the west side of the property during the next few weeks.

March 9, 2022: Following is a brief update on what has been happening at the project site.

Excavation for both tanks is substantially complete.

  • The excavation crews will demobilize some of the equipment on Friday, March 11. A large trailer will be on-site, and there may be temporary traffic impacts on Patterson St.
  • Crews next will begin installing a layer of crushed rock within the footprint of the tanks and perform general cleanup at the site.

The tank construction contract is open for public bidding.

  • The Board of Commissioners will be asked to approve a contract at their April 5 public meeting.
  • Tank construction is anticipated to begin mid-April or May and last 18-22 months.
  • During the tank construction phase, neighbors can expect truck traffic and equipment noise, interspersed with relatively quieter stretches of time in between concrete pours.

Jan. 25, 2022: Following is a brief update on what has been happening at the project site.

  • Crews are continuing to remove and haul the rock that was blasted for Tank 1. Blasting was completed in late-December, several months ahead of schedule. Hauling will continue for the next few months, resulting in continued high truck traffic and excavation noise.
  • Plastic sheeting was installed on the south side of Tank 2 in an attempt to control erosion of the exposed slope and to keep workers safe. If the plastic sheeting is not successful, we may need to implement additional measures such as wire mesh and/or shotcrete (sprayed-on concrete).
  • Survey work was completed for the new pipeline. The 36-inch water transmission main will be constructed between West Amazon St. and the intersection of East 40th Ave. and Patterson St. To minimize costs and traffic impacts, the pipeline work will be timed to coincide with planned City of Eugene street repairs.
  • Three viewing benches have been installed--two on the west side and one on the east side of the site. The benches provide a safe spot for members of the public to observe construction and learn more about the infrastructure that allows all of Eugene to enjoy safe, reliable drinking water.

For more information, read our Jan. 25 email to neighbors.

Dec. 27, 2021: We are happy to report that the controlled underground blasting phase of the project is now complete.

Following is the schedule for the next few days:

Monday, 12/27 - No work due to weather conditions.

Tuesday - Thursday, 12/28-12/30: Work will be weather-dependent. Minimal work preparing the site to start removing material within the footprint of Tank 1.

Friday, 12/31: No work due to holiday.

The next several months will primarily involve removing and hauling the rock that was blasted for Tank 1. Area residents can expect high truck traffic and excavation noise.

Thank You

As we approach year-end, the project team would like to take a moment to thank site neighbors and all the members of our extended community for your patience and understanding during the first few phases of this project. EWEB works year-round throughout our community on maintenance repairs, capital projects, and facility renovations to strengthen utility infrastructure and ensure Eugene homes and business have safe and reliable power and water. However, we recognize that the E. 40th project is extraordinary in scope, scale and location, and this first year in particular has acutely impacted surrounding neighbors. Thank you for your perseverance and for the ongoing constructive dialogue about ecological protection, public access, construction impacts and other topics.

Dec. 3, 2021: With just 11 blasts remaining for Tank #1, we have an opportunity to complete the blasting and drilling by Dec. 23 by increasing the number of blasts per week.

Read our Nov. 12 email to neigbhors for additional updates.

Nov. 7, 2021: Contractors completed paving of the entrance last week.

The paved entrance in intended to reduce the amount of sediment leaving the site and entering the gutter. With this new erosion control measure in place, excavation will continue. Please be prepared for a resumption of dump truck traffic on Monday morning (Nov. 8).

At this time, we expect the twice-a-week blasting schedule will resume on Tuesday, Nov. 9. However, there will be no blast on Thursday, Nov. 11 as this is a Federal holiday (Veterans Day).

It's possible that a second blast might be rescheduled for another day during the week of Nov. 8 (to make up for the missed 11/11 blast). If a second blast is planned, we will inform neighbors in advance.

On Nov. 2, EWEB's contractor conducted a controlled underground blast at the E. 40th water storage site. An incident occurred during the blast which resulted in flying rock and debris.

While there were no injuries, a house adjacent to the construction site sustained some cosmetic damage. Although blasting is performed through a professional subcontractor, EWEB is ultimately responsible for the overall project and is taking this incident very seriously. We are committed to doing our part to maintain a safe and well-managed worksite, and to protect the safety of our customers.

EWEB's project manager was on-site at the time of the incident. The immediate response was:

1.    Safety - check on neighbors who were in the area when the incident occurred.

2.    Cease work - contractors were instructed to stop all work on the site.

A Root Cause Analysis Report was performed by the blasting contractor to determine what happened, why it happened and what the contractor can do to make sure it doesn't happen again. 

The analysis determined the incident resulted from an oversight by a drill operator. 

The operator drilled a partial hole, then abandoned the hole without placing a visual marker to alert the blasting crew. Because the partial hole was unknown, the blasting crew did not take measures, such as packing and fully covering the hole with blasting mats, to prevent material from being ejected during the blast. No problems were identified with the design, material or equipment used in the blast. 

The contractor submitted a plan to EWEB for preventing similar incidents from occurring in future blasts. 

The plan includes expanding the footprint of blast mats to extend 20 feet past the last loaded hole, and retraining workers to ensure they mark any drill hole anomalies with visible flags. EWEB's Safety Office reviewed the contractor's plan. We are satisfied that these corrective actions are appropriate to prevent future incidents. Controlled blasting resumed on Tuesday, Nov. 9. 

Listen to EWEB project team's interview with KEPW Eugene Community Newswire.

Nov. 4, 2021: Here's a quick update on work at the site.

Contractors will be paving the entrance to the site on Friday, Nov. 5. The paving is intended as an additional erosion control measure to reduce the amount of sediment leaving the site and entering the gutter. Since the entrance will be unavailable during paving, there will be some trucks parked on Patterson St. on Friday.

Also on Friday, drilling work will resume.

Several more blasting mats have been delivered to the site as part of the contractor's additional safety measures following the Nov. 2 blasting incident. Once we have verified all remedies are done and in place, we will authorize the contractor to resume blasting. At this time, we expect blasting to resume on Tuesday, Nov. 9.

Nov. 3, 2021: We have asked the contractor to prepare a letter to neighbors with additional information about yesterday's blasting incident, their analysis and safety measures.

We will forward the letter to you as soon as we have it. In the meantime, here is an update from the EWEB project team.

Nov. 3, 2021: EWEB staff and contractors met on the job site early this morning to discuss yesterday's blasting incident and next steps.

We expect a full Root Cause Analysis Report from the contractor shortly. The analysis will identify what happened and corrective actions necessary to prevent future incidents. 

Blasting work is postponed until the root cause analysis is complete. However, we have allowed some work on the site to resume today. Read more.

Nov. 2, 2021: An incident occurred during today's blast which resulted in flying rock and debris.

What we know:

This was not supposed to happen. Underground controlled blasting is a common infrastructure construction method that involves extensive safety measures to contain debris and keep people and structures safe.

Safety is our #1 priority. EWEB will not allow work to continue until a full investigation is complete and the contractor provides full assurances that safety measures are in place to prevent this type of incident from occurring again. 

What we don't yet know:

Why this incident occurred. The investigation will provide a cause for the incident.

The vibration and sound measurements of the blast. The contractor will prepare an analysis of seismograph data to verify the vibration and sound measurements.

Read our Nov. 2 email to neighbors.

Nov. 2, 2021: This is just a reminder that today is a blasting day.

The current blasting schedule is Tuesdays and Thursdays between 1-1:30 p.m. The actual blast will last only a couple of seconds.Horn safety signals will sound 5 minutes and 1 minute before the blast and at the conclusion of the blast.

If you are near the construction site and hear a horn signal, please be aware blasting activity will occur shortly and follow instructions of site personnel or any additional signage that may be posted.

See videos of the blast that took place last week on Oct. 28.

The blasting schedule is subject to change based on weather conditions and overall project status. If there is a change to the Tuesday/Thursday blast schedule, we will notify you in advance.

Oct. 28, 2021: The first underground controlled blast occurred today just after 1 p.m.

Here are some photos and video from today's events.

Oct. 25, 2021: Following is a round-up of recent activities on the water storage project.

Third-party pre-blast home inspections are nearly complete. TerraFirma will email the reports directly to homeowners this week.

The additional, unplanned work to reduce the slope angle on the west side of the site is complete.Excavation of topsoil around Tank #1 (east side) is nearing completion. Excavation for Tank #2 (west side) is about 60% complete.

Drilling is beginning this week. Drilling hours are anticipated to be 7:30 a.m. to 5 p.m. M-F. We expect this will be the noisiest phase of the project and will last 6-8 months.

Blasting is tentatively scheduled to begin this Thursday (10/28) at 1 p.m. The first blast will be a small, test. Starting next week, blasting is expected to take place on Tuesdays and Thursdays between 1-1:30 p.m.

Six seismographs/vibration monitors have been installed around the perimeter of the site.In the next couple of weeks we will be installing a temporary construction power supply. The new conduit will be bored from an electric box near 4065 Hilyard St. There could be traffic impacts on Patterson St. that day.

EWEB, the contractor and City staff continue to work together to adjust and improve stormwater management. The switch from dry weather best management practices (BMP) to wet weather BMPs is causing some mud build-up on Patterson St., and we have requested a meeting with the City so that we can make adjustments that align with our erosion control permit.

The contractor is sweeping Patterson St. multiple times a week to keep mud to a minimum. We have asked the contractor to move the "biobags" during street cleaning and then replace them afterward. This should help keep bags and surround areas a little neater.

Benches are here! We will be putting two on the west side of the construction site and one on the east side to provide a place to watch the construction.

Oct. 23, 2021: Notice of potential weekend work

The contractor may need to pump out the drainage tank this weekend due to the amount of rain expected. They will potentially be checking on the site multiple times this weekend. If they have to pump out water, they will use a diesel generator powered pump, which will be noisy for a short amount of time.

Oct. 7, 2021: The construction crew has run into an issue with a section of the excavated slope on the west side of the site.

In this 30-foot section, the slope is crumbling sandstone and per Oregon Safety and Health Administration (OSHA) guidelines could create a potential safety hazard for workers.

We need to resolve this issue quickly for the safety of the work crews. To that end, we evaluated the following options:

1. Shore up the slope - Using shotcrete (sprayed concrete) can stabilize the slope but is very expensive and would add significant time to the excavation process.

2. Flatten or reduce the slope angle - this is a faster and least expensive process but requires us to expand the tank construction zone to the west, impacting about 10 trees on the margin of the work site.

3. Move both tanks to the east - this option would shift the tanks approximately 10 feet to the east. This would require removal of the several remaining fir trees on the east side and would further impact homes on this side of the property.

After evaluating the three options, we have determined that reducing or flattening the slope angle is the best solution. On Friday, we will begin the work to lay back an additional approximately 10 feet of slope.

To learn more, read our Oct. 7 email to neighbors.

Oct. 3, 2022: Following is a round-up of recent activities on the water storage project:

  • Topsoil excavation is still underway and on schedule.
  • A third-party contractor is performing pre-blast home inspections for neighbors within 500 feet of areas to be blasted.
  • EWEB's Safety Officer visited the site to take noise measurements. Noise was within acceptable OSHA limits on the property and workers on the site were using appropriate safety measures while the equipment was operating.
  • EWEB met with the Lane Regional Air Protection Authority (LRAPA), the City of Eugene and the Contractor to discuss dust mitigation. As a result, additional rock was installed over the haul roads on the site, one laborer from the construction company has been dedicated to spraying down the haul road and each dump truck load as it leaves the site when conditions are dry, and dump truck load size has been reduced.
  • EWEB, the contractor and City staff worked together to improve stormwater management. Check dams were installed to keep turbid water from the newly installed rock on the haul routes from running off the site into the gutter.
  • EWEB hosted a drop-in information session for neighbors at the project site. The contractor was available to answer questions about controlled drilling and blasting.
  • EWEB worked with the contractor to add more signs on E. 40th that alert drivers to trucks entering the roadway.
  • Drilling work to prepare the site for underground blasting will begin soon. Expect elevated noise levels during the drilling phase.
  • Drilling and underground blasting is expected to begin the second or third week of October.

For more information, read our Oct. 3 email to neighbors.

Sept. 23, 2021: Excavation work will extend to 6 p.m. today and tomorrow.

Crews are continuing to remove top soil in preparation for the next phase of excavation, drilling and underground controlled blasting. The extra work hours will help crews make up some time lost due to recent weather-related issues.

Sept. 8, 2021: Site preparation activities are still underway and on schedule.

Crews are removing approximately 15 feet of top soil in preparation for the next phase of excavation. Once the soil is removed, controlled drilling and blasting will be used to loosen and fragment in-place rock materials to a size that can be removed, transported, or crushed. The contractor anticipates that drilling and blasting will begin during the first or second week of October. During the next few weeks, the contractor will submit to EWEB a blasting safety plan, vibration monitoring plan, and work schedule. The plans and work schedule will be shared with neighbors and posted on our website.

For more information, read our 9/8/21 email to adjacent neighbors.

August 24, 2021: What's happening at the site?

Site preparation activities continue this week (8/23-8/27) including stump removal, hauling wood materials, and ­­other work to prepare the site for excavation. Additional excavation equipment will arrive next week. For the next 6-8 weeks, crews will be working on removing topsoil. Approximately 15 feet of soil will be removed and hauled off-site, in preparation for controlled drilling and blasting. In addition to excavation equipment noise, there will be dump trucks coming and going, using the Hilyard Street route.

For more information, read our Aug. 24 email to adjacent neighbors.


August 18, 2021: On Wednesday, Aug. 18, the Land Use Board of Appeals (LUBA) lifted the temporary stay, clearing the way for work to continue on the water storage project.

Site preparation activities will resume on Thursday, Aug. 19 including prepping and felling the remaining trees within the construction footprint, stump removal, and ­­other work to prepare the site for excavation.

Reminders regarding general construction impacts:

  • Workers, trucks, and equipment will generally begin arriving on-site around 7 a.m
  • We will only do work during hours that the City of Eugene noise ordinance allows and we will communicate work hours as the work progresses.
  • Truck noise such as beeping is not easily mitigated as that is an OSHA-required safety feature and needs to be loud enough for someone to hear while wearing hearing protection. When possible, trucks will be routed around the site to avoid the need to back up.

While we can't anticipate or mitigate all impacts, we will be responsive to your questions, suggestions, or concerns. Please reach out to us directly so that we can quickly address any issues that arise by email at water.storage@eweb.org or by phone at 541-685-7899.

For more information, read our Aug. 18 email to neighbors.

August 14, 2021: At the Aug. 3 EWEB Board meeting, Commissioners approved a contract for excavation services to facilitate the construction of two new seismically resilient water storage tanks at the E. 40th site. During the next few weeks, the contractor will submit to EWEB a blasting safety plan, vibration monitoring plan, and work schedule. The plans and work schedule will be shared with neighbors and posted on our website.

What to expect next week:

  • We will continue with LUBA's temporary stay order.
  • Site clean-up will continue on Monday, Aug. 16.
  • Chipping downed wood will take around 5-7 days and will result in increased noise levels relative to existing conditions.
  • Excavation equipment will begin arriving on the site Wednesday, Aug. 18.

For more information, read our Aug. 14 email to neighbors.

August 3, 2021: We have been advised by legal counsel that downed trees are not part of the LUBA order, and that we can proceed with limited clean-up work.

The contractor will be back on-site Wednesday, Aug. 4 removing limbs and stockpiling logs. Trucks and crews will begin arriving at the site around 7 a.m. and work will begin at or close to 8 a.m.

Consistent with LUBA's order we will not be doing any additional tree felling or stump removal at this time.

August 3, 2021: On August 2, the Land Use Board of Appeals (LUBA) received a notice of intent to appeal the erosion prevention permit that was issued by the City on July 30, 2021. Later that day, EWEB received an interim stay issued by LUBA which temporarily halts work while LUBA reviews the merits of the appeal.

We want to assure our community that we have adhered to all land use requirements. We are coordinating with our legal counsel to work through the LUBA process so that we can resume work on this project to provide secure, reliable water storage.

Tree removal work is nearly complete, but we will not be able to remove the downed wood until we are cleared by LUBA to resume work.

We are unsure how long the stay will be in place. However, the LUBA order requires responses to be submitted by Monday, Aug. 9. We will share more information as it becomes available.

In the meantime, you may see some limited activity on the site unrelated to tree work. For example, the contractor will be installing more rock for erosion prevention in anticipation of rain in the forecast, and we will be making some repairs to an area of fencing that was damaged.

For more information, read our August 3 email to neighbors.

July 31, 2021: As we begin construction, we want to assure you of the extra precautions we are taking related to fire risk.

While there are no tree removal restrictions within the Eugene Urban Growth Boundary per City fire code, EWEB will adhere to the Oregon Department of Forestry (ODF) restrictions and is taking other proactive risk mitigation measures. The contractors will strictly adhere to the IFPL work schedule (no fire-risk activity after 1 p.m.), continuously monitor conditions throughout the day, and adjust work and mitigation strategies accordingly.

Additionally:

  • A new hydrant was installed at the west entrance of the property. This gives the contractor a path to install a fire hose across the site to have water available throughout construction.
  • The contractor will have two water trucks onsite, one dedicated for fire mitigation and one for dust mitigation.
  • The contractor is removing the vegetation around the work zone down to the bare ground and installing rock up to the tree line. This reduces fire risk and helps with dust mitigation.
  • A minimum 3-hour fire watch will be provided by the contractor after work stops for the day. Additionally, EWEB will have 24/7 security at the site who will be able to call 911 and EWEB's security lead if they see anything concerning after fire-watch.
  • EWEB has been communicating with the Eugene Fire Department regarding schedule and mitigation plans. They are aware of the work and the work schedule and will be ready to respond if an issue should arise, as well as to consult with us if a red flag warning goes into effect in the area.

For more information, read our July 31 email to neighbors.

July 26, 2021: This week, Northwest Youth Corps will be at the site doing invasive weed removal. Blackberry and other invasive weeds are common ladder fuels for wildfire and hamper forest health. Expect to see Northwest Youth Corps on-site July 28-29.

Fencing and tree removal:

  • Fencing and erosion control will be installed during the last 2 weeks of July. The fencing will be chain link, and will be limited to the construction zone on the northeast side of the property. The west and south sides of the property will remain open to the public during most phases of construction. The fencing will remain in place throughout construction (2.5 - 3 years). 
  • During the last week of July, equipment will arrive at the site. Once the equipment arrives, a 24x7 security contractor will be onsite (in a truck parked at the Patterson St. entrance). The security is there to keep equipment safe and is a temporary measure until we have a more frequent presence at the site. 
  • Tree removal will begin in early August. The process to take down, chip and haul wood will take approximately 3-4 weeks. During that time, there will be chainsaw noise, chipper noise, and truck traffic. Work will not begin before 8 a.m. and will be complete by 4 p.m. Monday - Friday. 
  • Approximately 75% of the trees on the site will be left standing. Only the trees in the footprint of the tanks are being removed. 
  • We are keeping all of the downed wood in the community. When possible, we will create snags and leave downed trees on the site for birds and other wildlife to use for nests, nurseries, storage areas, and perching. Other downed trees are being donated to a City of Eugene wetlands restoration project, where they will continue to provide habitat long into the future, and for public use projects in the Southeast Neighborhood and also the City of Springfield. 
  • The tree removal contractor has determined that log trucks will use Hilyard Street to travel to and from the site. Removal of downed trees will take approximately two weeks.


Earthwork:

  • Earthwork will begin mid-September and will last 6-8 months. 
  • This will be a disruptive period of noise and truck traffic. We will host another neighbor meeting in August (date TBD) to discuss construction details and mitigation. 

For more information, read our July 26 email to neighbors

July 9, 2021: On the evening of July 7, EWEB held a meeting on the project site to inform adjacent neighbors about the next steps and to kick off the landscape design process. Several Eugene areas residents attended as well.

Following is a summary of the information that was shared at the July 7 meeting:

Fencing and tree removal:

  • Fencing and erosion control will be installed during the last 2 weeks of July. The fencing will be chain link, and will be limited to the construction zone on the northeast side of the property. The west and south sides of the property will remain open to the public during most phases of construction. The fencing will remain in place throughout construction (2.5 - 3 years).

For more information, read our July 9 neighbor email

June 1, 2021: On May 26, the project team hosted an online meeting with neighbors who live adjacent to the E. 40th water storage site. The meeting drew a small group (6 neighbors), which lent to a pretty informal presentation and conversation. 

The project team reviewed where the tanks will be constructed (previously shared with neighbors in April 14 email) and anticipated dates of activity at the site, which at this point include:


Pre-construction

  • Anticipated late July
  • Includes fencing and erosion control


Tree removal

  • Anticipated to begin August 2
  • Will take 6-8 weeks


Earthwork

  • Anticipated to begin September 15 
  • Will take 6-12 months, including drilling, blasting, excavation, and rock removal for both tanks


We also discussed how access to the site will change in the near future, and some things adjacent neighbors can expect in the coming months:

  • Fencing will change/limit access on the north side of the property throughout construction
  • The summit/viewpoint will remain accessible, but the ridgeline trail to the east will be closed
  • Tree removal will bring chainsaw noise, heavy equipment, log trucks
  • Patterson Street will remain open during tree removal; some traffic control is possible

May 10, 2021: Construction activity tentatively planned to begin August 2, 2021

With the important decisions about tank placement and construction sequence now established, the water storage project is moving into the detailed design, construction bidding, and scheduling phases. The following dates are tentative; we will update this site if the schedule needs to be pushed out due to weather conditions or any other potential delays.

    • May 12 - 14, 2021: Geotechnical fieldworkTechnicians from Foundations Engineering, Inc. will be on-site to perform additional fieldwork.

    • August 2, 2021: Anticipated date to begin tree removal. We estimate this work will take 6-8 weeks. Approximately 265 trees will be removed, which is around 25 percent of trees on the 10-acre site. For healthy trees that are on the margin of the construction zone, we will conduct critical root zone assessments to determine if the trees could potentially survive the disturbance and could therefore be left in place. When possible, we will create snags for birds and other wildlife to use for nests, nurseries, storage areas, and perching.

  • September 15, 2021*: Anticipated date to begin earthwork/excavation. We estimate this work will take 6-12 months for drilling, blasting, and excavation including rock removal and hauling for both tanks.

*On May 26, this date was updated from Sept. 1 to Sept. 15.

April 20, 2021: Construction of two new water storage tanks in SE Eugene to begin later this year
After more than a year of research and planning, EWEB is preparing to move forward with construction of new water storage facilities on an undeveloped property near E. 40th Ave in southeast Eugene. The 10-acre property was acquired by EWEB in 1950 as a future water storage site.

Preliminary plans had called for building one 7.5 million-gallon (MG) tank at the E. 40th site beginning in 2021, then returning several years later to build a second 7.5 MG tank. But at their April 6 meeting, EWEB's elected Board of Commissioners endorsed a decision to construct both tanks concurrently commencing in 2021. 

The decision follows multiple studies by EWEB and external parties to evaluate site layout and construction options considering drinking water safety and quality requirements, engineering and construction constraints, impacts to neighbors, environmental considerations, and costs.

November 6, 2020: Thank you to everyone who provided input to DOWL for the ecological study at the site. We expect to have the report back from DOWL by early December and will share it with neighbors.

A contractor will be on-site Nov. 9 - 13 to complete additional geotechnical investigations. Geotechnical investigations are used to evaluate the physical characteristics of the underlying soil and help determine appropriate excavation methods. In early 2019, a preliminary investigation indicated that blasting would be recommended at the E. 40th site. November 9-13, another contractor will be on-site to perform an additional round of geotechnical work and provide a second opinion.

Learn more (11/6/2020 email to Neighbors).

October 2, 2020: The Holiday Farm Fire delayed some work on the ecological study but things are now moving forward again. The study will identify sensitive habitat and species and help inform the tank design and landscaping plan to preserve and protect sensitive species during construction and restore the site to enhance the habitat afterwards. 

Surveyors have marked the preliminary center point and edges for the first tank.  The initial survey and markers are still preliminary-the tank placement may be revised a few feet in any direction as the detailed design work progresses. The surveyors also took measurements on Patterson Street for pipeline construction.EWEB Commissioners visited the property in late September to get a first-hand look at the preliminary tank siting and to better understand how the project will affect neighbors and habitat. In advance of the Oct. 6 Board meeting, the project team has provided an informational update to Commissioners in order to solicit additional Board guidance regarding the current project path.

Learn more (10/2/2020 email to Neighbors).

August 21, 2020: At the August 4 EWEB Board meeting, Commissioners approved a contract with Murray Smith Associates of Portland, OR for design and engineering-related services for new 7.5 million-gallon (MG) storage tank on the E. 40th Avenue site. The contract with Murray Smith Associates specifies that design services will be completed by spring 2021, which will allow construction to begin summer 2021.

To better understand and address the potential environmental impacts of this project, EWEB is contracting with the consulting firm DOWL to conduct an ecological study at the site. The study will identify sensitive habitat and species and help inform the tank design and landscaping plan to preserve and protect  sensitive species during construction and restore the site to enhance the habitat afterwards.  Learn more (8/21/2020 email to Neighbors).

June 25, 2020: The City of Eugene Planning Department has determined that construction of public water storage at the East 40th site is an allowed use, and does not require Planned Unit Development (PUD) approval. This decision creates more certainty for the timeline moving forward. Our goal is to complete the design and construction of one 7.5 MG tank at East 40th Ave. and bring that facility online by mid-2023. Learn more (7/2/2020 email to Neighbors).

May 21, 2020: An arborist will be on-site beginning the week of May 25 to assess and document the condition of trees on the east side of the property, in the area where the first tank will be constructed. This assessment will be used to develop a tree preservation plan, which is part of the permitting process. The arborist will mark trees to record which have been assessed. The markings do NOT indicate which trees may be removed or retained. They are simply for keeping track of which trees were evaluated. Surveyors will mark trees for removal at a later date. The arborist work is expected to take approximately four days over a two week period.

May 6, 2020: EWEB recently conducted a survey of neighbors who live adjacent to the E. 40th water storage site. The goal was to collect input about landscaping, walking paths and other features that honor the special nature of the 10-acre open space and ridgeline. Approximately 40 households were invited to participate in the online survey, which was administered in place of a community meeting due to COVID-19 social distancing requirements. See the survey results.

March 5, 2020: We held a meeting with immediate neighbors to introduce the project team, share early information about plans for EWEB's water storage facilities, and hear comments and concerns from neighbors who live adjacent to the site. We compiled some of the themes we heard at the meeting and posted them on our website.

College Hill

July 9, 2021: College Hill Reservoir to be decommissioned by 2023
After serving Eugene for over 80 years, the 15 million-gallon (MG) College Hill Reservoir has reached the end of its useful life. The reservoir does not meet current seismic standards and requires significant, expensive repairs to protect the drinking water inside. To meet Oregon Health Authority requirements, EWEB plans to take this reservoir out of service by the end of 2023. 

To continue providing the safe, reliable drinking water our community depends on, EWEB will need to replace the College Hill Reservoir with new water storage infrastructure. 

Although we plan to take College Hill out of service by the end of 2023, pending completion of the replacement storage at East 40th, EWEB has not yet determined a demolition and construction schedule for the concrete tank.

We will keep neighbors informed as we continue to assess and refine the construction plan for College Hill.

Learn more and join our project email list to receive future updates.

April 20, 2021: For the past year or so, you have been hearing about plans to replace the 15 million-gallon (MG) College Hill Reservoir with new water storage infrastructure. Construction had been planned to begin mid-2023, but a recent decision by the EWEB Board of Commissioners to focus the utility's efforts on building two new tanks at another site means that EWEB will have an opportunity to rethink the timing for rebuilding at College Hill.

We still plan to take College Hill out of service by the end of 2023, per OHA requirement, pending completion of the replacement storage at East 40th. But EWEB has not yet determined a new demolition and construction schedule for the concrete tank.

We will keep neighbors informed as we continue to assess and refine the construction plan for College Hill. Watch for communication later this year with updates on the public engagement timeline for both historic mitigation and landscape design.

July 2, 2020: The City Planning Department has determined that construction of public water storage at the East 40th site is an allowed use, and does not require Planned Unit Development (PUD) approval. This news is significant to College Hill for two reasons: 

1) It means construction at College Hill likely will not begin until mid-2023.

2) It allows the option to site the new College Hill tank within the footprint of the existing reservoir.

March 5, 2020: Landscapers will be on-site March 26 to blow-in grass seed and repair areas that were damaged during geotechnical work

February 24, 2020: The north side of the College Hill roof will be closed to the public from Feb. 25 - March 2 while a contractor works to re-seal the joints. These joints were resealed November 2018, but have failed. Temporary fencing will restrict access to the north side and the gate will be locked to prevent public access while this work is being done, and to allow cure time for the repairs. We anticipate that normal access will resume Monday, March 2. The south side of the reservoir will remain open as usual. 

February 21, 2020: EWEB will be working with a contractor to complete geotechnical investigations at our College Hill and Hawkins Hill water storage facilities. The purpose of the geotechnical investigations is to evaluate the physical characteristics of the underlying soil to aid in the design and construction of new water storage tanks. 

  • A contractor will put stakes in the ground Feb. 26 to mark boring locations.
  • Boring will take place between March 2 - 11 at both the College Hill and Hawkins Hill water storage facilities. The work is anticipated to take up to four days.
  • Hydraulic equipment will be used to drill multiple borings. The holes will be back-filled.
  • For safety reasons, some areas of the property may have restricted access during drilling.
  • The work may be noisy but will be contained to EWEB's site. 

January 30, 2020: We held a meeting with immediate neighbors to introduce the project team, share early information about plans for EWEB's water storage facilities, and hear comments and concerns from neighbors who live adjacent to the site. We compiled some of the themes we heard at the meeting and posted them on our website.

Hawkins Hill

July 9, 2021: Future updates planned for Hawkins Hills water storage
In addition to the work at E. 40th Ave. and College Hill, a third water storage project is in the capital plan-building two new 7.5 MG tanks at Hawkins Hill to replace the existing 20 MG tank built in the 1960s.
This project is still in the earliest planning stages. As planning progresses, we will reach out to neighbors to discuss site layout, construction, and other details.

These inter-related projects are part of a significant investment aimed at diversifying EWEB's water storage system with additional, but smaller tanks, to enhance resiliency, water quality, and systems operations.
