Day-long power outages from June-uary winds and rain that hit over 7,000 Seattle City Light customers in northern Capitol Hill earlier this month didnβt have enough of an impact for the city to consider installing underground power lines. The location of Capitol Hill power outages follows a pattern: in areas where multifamily housing development is less prevalent, power lines sit above ground and are left vulnerable to high winds and storms.
βThe recent, sustained high wind event caused many outages throughout our service area including Capitol Hill,β Jenn Strang, media relations manager of SCL, told CHS.
Power outages are frequently caused by fallen trees, wind and ice. Strang said some instances are easier to fix than others, like the outage at 15th St and E Olive St.
βIn the case of Mondayβs outage at 15th Street East and East Olive, multiple wire spans and crossarms needed to be replaced and repaired which required different crews to complete the tasks,β Strang said.
Installing power lines underground to lessen the risk of outages in the area isnβt an option without larger scale housing development.
For one, it’s expensive — and the city wants developers to pay for it.
Nicholas Rich, client executive at IMEGβa national engineering and design consulting companyβ said many owners of newly built apartments want City Light to bury overhead power lines underground.
βIf you put those underground you really improve the reliability in that respect locally,β Rich told CHS. βUsually a new developer wonβt want to do that because City Light is perfectly happy keeping those overhead lines just the way they are.β Continue reading →
