Columbia Park Neighborhood Association

Does anyone remember what company was working on the sidewalks on Monday, 8/3?  One of their employees was urinating in the alley between 36 1/2 and 37th on Monday afternoon.  I've made a complaint with the city, but the city has called back asking what the name of the company was.  I thought it was Blaine Sidewalk Service?  But I can't find any business with that name
