The 3-D video display that lights up the courthouse in downtown Redwood City once a week will soon be going in for a spooky makeover.

“In October, they’re actually going to be switching out the video mapping with a new video mapping to go along with a Halloween theme,” said Courtney Rose, of Olive PR Solutions.

She was referring to the Redwood City Improvement Association, which formed last September and considers the Tuesday night light show that debuted in April its centerpiece enhancement to downtown. The new light show, titled “Dias de las Muertos,” will begin in September and run through November, according to Rose. The association plans to install a new show every few months.

The group is helmed by a board made up of property owners, residents, community members and businesses, presided over by interim president Eric Lochtefeld. Its aim is to re-energize and beautify the city’s downtown.

The association levies a fee based on square footage of each building, lot size and frontage area on all property owners in its coverage area, which includes 222 parcels.

The total amount collected in its first year of operation, which ends this month, was $795,781. The largest chunk — $423,000 — went toward sidewalks and was funded entirely by the $9.50-per-square-foot frontage fee. The association staffs workers who power-wash sidewalks and take out the trash daily. It recently added a third valet spot — at the corner of Main Street and Broadway — where visitors can drop off their cars, which are parked at lots after operating hours through an arrangement with several businesses.

The board is scheduled to elect permanent board members at its September meeting.
