Generators are crucial to pump out water, support fresh air system in deep shafts
We’ve been asked by a few residents about generators that are on the surface at several locations in the project area, what they’re being used for, and why they are operating and causing some level of noise 24/7.
These generators are needed in order to pump out groundwater from the shafts and keep them from flooding. The generators must run 24/7 to prevent after hours/weekend flooding and damage to the equipment in the shaft (which causes delays in the project). With significant rains predicted in the coming days, this “dewatering” is even more critical.
In addition, the generator supplies power to the fresh air support system for crews who are working in the shafts, which are 40-45 feet deep.
We apologize to anyone who may have experienced some disruption due to the 24-hour-a-day operation of the generators. We are taking measures to reduce the noise, and are working hard to complete this part of the project so they can be removed. However, for the time being running these generators 24/7 is absolutely crucial for the prevention of flooding in the shafts and the safety of work crews.
Attention motorists: use extra caution on Halloween
Halloween is a week from this Sunday, and that will mean kids and families out in the evening walking on sidewalks and crossing streets. Please be extra-careful when driving on Chanate Road, nearby roads, and the detour streets, particularly around dusk on Halloween – and be especially watchful for trick-or-treaters.
Some general reminders for motorists:
- Check your speed and observe speed limits – never drive faster than is safe for the conditions
- Use extra caution and watch for equipment and materials
- Allow additional time to reach your destination
- During working hours, watch for work crews
If traveling through the two temporarily-opened emergency vehicle access points (Terra Linda Drive/Lake Park Drive, and Andy Way/Baldwin Way), proceed slowly and carefully – access is in the northbound direction only.
Thank you for your attention to safety on the the roads!
Reminder: Chanate Road westbound lane closure/detour extended into late November
Due to unforeseen circumstances, the detour of westbound traffic (including bicyclists) on Chanate Road between Terra Linda Drive and Humboldt Street is now anticipated to extend into late November 2021.There have been unexpected subterranean conditions (up to 40′ underground) that have slowed the installation of the pipeline. This includes having to get through an unexpected, very large boulder and other unanticipated soil conditions, as well as encountering some unmarked underground cables that crews had to work around, which also required some redesign.
As has been noted in each of these weekly update emails, the construction schedule is always subject to change due to unforeseen circumstances – and unfortunately such circumstances have occurred which are beyond the control of the City and its contractors. We apologize for this extension, and appreciate everyone’s patience as construction crews continue working diligently to be able to remove the detour by Thanksgiving.
We will keep you updated should there be any further changes to the schedule. Please note that once the detour is removed and westbound traffic on Chanate Road is restored, daily traffic control and temporary lane closures will continue as other project-related work takes place. The two emergency vehicle access points (Terra Linda Drive/Lake Park Drive, and Andy Way/Baldwin Way) which are temporarily open will be re-closed shortly after the detour is removed.
During the detour, only eastbound, one-way traffic on Chanate Road is available. Pedestrian access is maintained on the north side of Chanate Road. If possible, please avoid the general area of construction throughout the project period. When using the detour route, allow plenty of extra travel time. Click here for a map of the detour. The City’s Fire, Police, and Public Works departments, and the project team have contingency plans to facilitate emergency situations that may occur during the detour of Westbound Chanate Road. If an evacuation is called for, construction on the project will be halted and, if necessary, the travel direction on Chanate Road (eastbound only during the detour) will be reversed to provide westbound-only movement for travel out of the area.
Temporary traffic signal lights now in place will be used only in the event of an urgent public safety issue requiring westbound traffic movement or emergency vehicle access on Chanate Road, during the detour period. Do not proceed when signal is red.
Please be sure to review the City’s Know Your Ways Out web page and neighborhood travel route maps.
