11:16 AM: The announcement is from Seattle Parks – we’re just mentioning the local fields on the list:
Seattle Parks and Recreation will turn on field lighting on ballfields throughout the city on the evening of Friday, July 3 and Saturday, July 4 to protect the surfaces. The ballfield lights will be turned on at approximately 8:30 p.m. and most 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 or surrounding facilities. The approximate replacement cost for the synthetic surface 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 players of soccer, football, baseball, Ultimate Frisbee, and lacrosse.
The fields will be monitored by security from 9 p.m. to 4 a.m. Lights at 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
West Seattle Stadium, 4432 35th Ave. SW
4:11 PM: The Port of Seattle has a plan too – received from spokesperson Peter McGraw: “Port police will be closing T105, T107, and Jack Block Parks around 3 p.m. this Saturday to prevent possible property damage related to firework use. The parks will reopen on Sunday morning.”
