Project Update - Phase 1 Work Complete (posted November 2, 2020)

Phase 1 of the Mission Trunk Sewer Project is now complete. Crews are working to dismantle the sewer bypass system along Arden Way east of Safari Court, and contractors will return for final paving in early 2021. Thank you to all the residents and businesses impacted by Phase 1 construction. We appreciate your patience!

Project Update - Bowerwood Drive (update October 22, 2020)

Phase 1 of the Mission Trunk Sewer Project is expected to be complete by late October, and Phase 3 work will soon begin. Here’s what to expect as Phase 1 nears completion and Phase 3 gets underway.

Relocation and Installation of Sewer Bypass System—starting late October and continuing for 4 weeks:

The Phase 1 temporary sewer bypass system that begins at the intersection of Bowerwood Drive will be dismantled and moved for the Phase 3 bypass route (see map below). Activities include the following:

  • Bypass equipment (pumps, generators, fencing, etc.) will be removed from Bowerwood Drive intersection
  • The Phase 3 bypass system will be installed with protective barriers along Mission Avenue and a section of the frontage road. This will remain in place from mid-November through February 2021
  • Large segments of the bypass pipes will be moved from the Phase 1 alignment and reused for Phase 3
  • Bypass pipes at Mission Avenue and Bowerwood Drive will be trenched to allow for vehicle turns
  • Mission Avenue will be open to two-way traffic up to Melvin Drive, where northbound traffic will be directed to a detour route
  • Street parking will be prohibited along Mission Avenue through February 2021
  • Trash, green waste, and recycling bins can be placed on the street per your normal pickup protocol unless otherwise notified

During most of the activities listed above, trucks and heavy equipment will use Mission Avenue to complete the work and some night work will be necessary.  We will take all reasonable measures to minimize construction impacts—including noise, odor, dust, and temporary traffic impacts. Please look for cones, flaggers, and construction signs, and exercise caution at all times around construction activities.

Project Update - Keane Drive (posted September 29)

This is an update on construction activities on Keane Drive between Oak Vista Drive and Copperfield Way.

Cured-In-Place-Pipe (CIPP) Installation— Begins October 10 and continues for 1 week:

What to Expect: In our previous update for Keane Drive, we stated that the CIPP installation would take about three weeks. The contractor has completed the first two weeks of work but will now need to return for the third and final week. Beginning on Saturday, October 10, crews will erect the preparation tent again to prepare the CIPP lining material, after which they will insert the liner into the sewer pipe through the existing junction structure. As a reminder, once the lining process begins, crews must work 24/7 to complete the process, and some weekend work may be necessary. Keane Drive will be closed through mid-October and detour routes will be clearly marked.

We will take all reasonable measures to minimize construction impacts—including noise, odor, dust, and temporary traffic, parking, and property access impacts. Please look for cones, flaggers, and construction signs, and exercise caution at all times around construction activities. Additionally, we will work closely with affected property owners before and during this work.

Project Update - CIPP Lining Underway (posted August 11)

This week, the Sacramento Area Sewer District (SASD) began the sewer lining phase of the Mission Trunk Sewer Project (see CIPP Lining Areas on map). SASD’s contractors will create a laydown area that spans about 150 feet over the insertion manhole, and the liner will be prepared and inserted through the manhole and into the sewer pipe. Once the lining begins, crews must work 24/7 to complete the process, and some weekend work may be necessary.

We will make every effort to minimize construction impacts—including noise, odor, dust, and temporary traffic, parking, and property access impacts. Please look for traffic detours, flaggers, and construction signs, and exercise caution at all times around construction activities.

Below is the lining schedule:

  • Mission and Arden – Mid-August
  • Barnett Circle – Late August
  • Del Dayo Drive – September
  • Keane Drive – September/October
  • Kingsford Drive – September/October
  • Sand Bar Circle – September/October

Project Update – Bowerwood and Mission (posted May 12)

During Phase 1 work for the Mission Trunk Sewer Project, Bowerwood Drive at Mission Avenue will remain closed, and northbound traffic on Mission Avenue will continue to be prohibited between Arden Way and Thor Way. Southbound traffic on Mission Avenue will remain open, and detour routes for northbound traffic will be clearly marked.

These ongoing lane and road closures are necessary to ensure public safety and facilitate the temporary sewer bypass system. Please look for cones, flaggers, and construction signs, and exercise caution at all times around construction activities and detour routes.

Bypass pumps, generators, and piping will be placed at the intersection of Mission Avenue and Bowerwood Drive and operate continuously until Phase 1 is complete. The bypass system will collect wastewater from the Mission Trunk to keep the community’s wastewater flowing to the treatment plant while repairs to the Mission Trunk are made.

SASD’s contractors will take measures to minimize noise and other possible impacts, such as dust and odor. Special equipment and noise reduction measures will be used to mitigate the continual operation of the bypass pumps. 

Project Update – Night Work at Fair Oaks/Arden (posted May 8) 

WORK COMPLETE

Phase 1 work has begun with the installation of a temporary sewer bypass system that will keep the community’s wastewater flowing to the treatment plant while repairs to the Mission Trunk are performed. During installation of the bypass, temporary night work will be required at the intersection of Arden Way and Fair Oaks Boulevard to bury the temporary sewer pipes so that the intersection can remain open during Phase 1.

WHAT: Night work for Mission Trunk Sewer Project

WHERE: Intersection of Arden Way and Fair Oaks Boulevard

WHEN: After a delay, work is now anticipated to begin Tuesday, May 26, and continue through Friday, May 29. Work hours will be from 8 p.m. to 6 a.m. each night. 

WHY: SASD’s contractors are installing temporary bypass pipes beneath the intersection to reduce traffic impacts to the surrounding community during Phase 1 construction.

While SASD’s contractors will take measures to minimize construction impacts, some noise and dust should be expected during the night work. In addition, lane closures will be necessary, but the intersection will remain open in all directions with flaggers directing traffic. Street parking will be restricted on parts of Arden Way. Traffic restrictions will be removed by 6 a.m. each morning.

Project Update – Upgrades to Facilities in American River Parkway (posted April 30)

The Mission Trunk connects to structures and pipes located at the Sheriff’s Academy near the American River Parkway. These facilities are owned and operated by the Sacramento Regional County Sanitation District (Regional San), your local wastewater conveyance and treatment provider. As part of the Mission Trunk Sewer Project, these Regional San facilities will be repaired or reconstructed. These improvements are necessary to upgrade the aging facilities, which are critical components of the wastewater conveyance system.

What to Expect: Beginning in early June, work will take place Monday through Friday between 7 a.m. and 5 p.m., and some weekend work may be necessary. During this time, contractors will make every effort to minimize noise and other possible impacts, such as dust and odor. After work hours, you may see security personnel whose job it is to monitor and protect the bypass pipes that connect to the facilities to ensure they are operating properly. Project work is expected to be complete in fall 2020.

Throughout construction, SASD and Regional San will maintain uninterrupted sewer service. Access to residences will be maintained at all times. Additionally, pedestrian and bike mobility will also be maintained. 

Safety Precautions: Safety is our number one priority. Please look for cones, flaggers, and construction signs, and exercise caution at all times around construction activities. Crews will follow strict protocols for traffic safety during construction and when equipment and materials are delivered.

Project Update – Phase 1 Bypass (posted April 17)

Beginning in April, work will start on Phase 1 of the Mission Trunk Sewer Project at the southern end of the Mission Trunk, which includes the installation of temporary bypass pipes. Bypass pumping is necessary to keep sewage flowing during this project, and during installation of the bypass, SASD’s contractors will need to use part of the westbound lane of Arden Way at the intersection of Kingsford Drive. This staging area is expected to be in place for approximately two months and will be used to store bypass pipes, materials and equipment, and fuse the pipe segments together. The following traffic control measures in your area are necessary to facilitate the work and ensure public safety:

  • Arden Way lane shift for westbound traffic at intersection of Kingsford Drive (two-way traffic maintained at all times)
  • Cones and traffic signs near intersection

Although the staging area will remain in place around the clock, active work will only be performed Monday through Friday between 7 a.m. and 5 p.m. SASD’s contractors will take measures to minimize noise and other possible impacts, such as dust and odor. Access to properties will be maintained at all times, as will pedestrian and bike mobility.

Project Update – Phase 1 Begins (posted April 7)

The Sacramento Area Sewer District (SASD) is beginning the Mission Trunk Sewer Project to address sewer pipe corrosion and return the Mission Trunk to optimal operating performance.

In mid-April, work will start  on Phase 1 with installation of a new manhole at the intersection of Bowerwood Drive and Mission Avenue. Temporary road closures are necessary to facilitate this work and ensure public safety. For up to two weeks, access to Bowerwood at Mission will be closed, and Mission will be closed to northbound traffic between Arden Way and Thor Way. Detours will be clearly marked. Southbound traffic on Mission Avenue will remain open.

Closures will be in effect 24 hours a day, but work will be performed during normal business hours. Access to properties will be maintained at all times, as will pedestrian and bike mobility. Contractors will make every effort to minimize noise, dust, and odor.
