Again this year, Seattle Parks will leave the lights on at synthetic-turf ballfields around the city to discourage fireworks. We’ve excerpted its citywide announcement to include the West Seattle fields it mentions (no WS fields will be turned off at 10):

Seattle Parks and Recreation will activate the field lighting on synthetic ballfields throughout the city on the evening of Thursday, July 4, to protect the synthetic surfaces. The ballfield lights will be turned on at 8:45 p.m. and will be turned off at either 10 p.m. or 11 p.m., depending on the field.

The lights will be turned on to discourage the use of fireworks. Fireworks are illegal in the City of Seattle and will destroy the artificial turf on the fields. The approximate replacement cost for synthetic carpet based on per average full size field (110,000 square feet) is $1.2 million. All the fields have been renovated in the past several years and benefit field users including soccer, football, baseball, Ultimate Frisbee and lacrosse.

The following fields will be turned off at 11 p.m.:
· Delridge Playfield, 4458 Delridge Way SW

· Hiawatha Playfield, 2700 California Ave. SW

· Walt Hundley Playfield, 6920 34th Avenue SW
