From the “in case you wondered too” file – the land-use-action sign out front of the Arco station at Delridge/Orchard is for major work that just got city approval this week. The owners plan to “remove 2 underground storage tanks and install two new tanks (one 22,000-gallon and one 25,000-gallon tank).” Also: “Existing piping system, dispensers, and trash enclosure to be replaced … (project) includes 1,800 cu. yds. of grading (900 cu. yds. of backfill).” Publication of the decision opens an appeal period, with a March 7 deadline; this notice explains how.
