Repairs Over Water? Check With the City First.

SDCI is reminding residents that if they need to make any repair over water they need to check with the City of Seattle first.

Two common shoreline violations are unauthorized pier repair and the use of pressure-treated with for pier surfaces.

If you are making repairs, you will need to apply for a shoreline exemption. Learn about the types of projects that qualify for an exemption on our Shoreline Exemptions website. Tip 209A, Shoreline Substantial Development Exemptions Application Instructions, provides more information about shoreline exemptions and how to apply.

Pressure treated wood can be identified by score marks on the surface and a green or orange color. We don’t allow you to use wood treated with preservatives because it’s toxic to fish, doesn’t degrade, and accumulates in the environment. While treated wood is low-cost and decay resistant, the chemicals are toxic to humans as well as aquatic life.

For more information about shoreline regulations, contact (206) 684-5040.

If you want to file a complaint, call (206) 615-0808.

City Light Completes Cable Injection in Lake Forest Park

Earlier this fall, Seattle City Light completed its silicone cable injection work in Lake Forest Park. The project began in September 2016 to enhance the reliability and extend the life of aging underground electrical cables in parts of Lake Forest Park by injecting them with silicone.

City Light’s contractor, Novinium, tested and where possible, injected about a mile of underground cable with silicone to fill cracks in the cable insulation to prevent outages. This work extends the life of the cable for an additional 25 years and improves electrical reliability.

Example photo of typical cable injection work.

Approximately 50 percent (half a mile) of the total underground cable from this project was suited to injection. The remaining 50 percent of cable was not suited for injection and will be replaced at a later time.

Past cable injection projects in areas such as Shoreline and Seattle’s Capitol Hill neighborhood have succeeded in extending the lifespan of aging cables and improving reliability at a lower cost than replacement. A 2011 cost comparison showed that the average cost of cable injection was $25, compared to $248 for cable replacement.

Shoreline Substation Construction Work to Increase Electrical Reliability

Beginning in early May, City Light plans to increase system reliability by replacing an old power transformer with a new one at the Shoreline Substation. The work will be similar to a new transformer installation that took place there in 2014. See the map for the location of the Shoreline Substation:

 

 

 

 

 

 

 

 

 

 

 

Construction will begin with jackhammering in the center of the substation yard during daylight hours in order to prepare the site for building the new electrical equipment. From approximately mid-August, crews will begin the assembly of the new transformer on its pad. Once assembly is complete, a truck-mounted mobile generator and oil processing tanker will be used to process the new transformer’s oil.

The upcoming construction work at Shoreline Substation is one of the many projects City Light carries out in order to maintain and improve electrical reliability in its service areas.

City Light Plans Silicone Cable Injection In Parts of Service Territory

Seattle City Light will start another project this October to enhance the reliability and extend the life of aging underground electrical cables in parts of Shoreline, Lake Forest Park and Seattle by injecting them with silicone.

City Light’s contractor, Novinium, will test and where possible, inject underground cables with silicone to fill cracks in the cable insulation to prevent outages. This work will extend the life of the cable for an additional 25 years and improve electrical reliability. If cables are not suited for injection, they will be replaced at a later time.

Please refer to the construction notification fliers for approximate construction areas:

This project is expected to start in early-to-mid October 2015 and extend for approximately six weeks. Work hours are scheduled for Monday to Friday, from 8:30 a.m. to 4:30 p.m. During construction, customers should expect some traffic and parking impacts in the immediate area. Crews will be careful to try and maintain access to driveways.

Several maintenance outages are required for this work. Affected customers will be notified the Thursday before the following week’s outage. The outage date and time will be specified on the notification.

Past cable injection projects in neighborhoods such as Sandpoint, Queen Anne and Delridge have succeeded in extending the lifespan of aging cables and improving reliability at a lower cost than replacement. A 2011 cost comparison showed that the average cost of cable injection was $25, compared to $248 for cable replacement.
