Ripon addressing Wilma flooding issues The Wilma Avenue roundabout in 2007 was one of several projects that raised the grade of the roadway along the 500 block of Wilma Avenue. The Ripon City Council recently hired DSR Construction, Inc. to handle the work on the Wilma Avenue Driveways Project. The reason for that has to do with the possibility of flooding in the event of intense storms. Three properties in the 500 block of Wilma Avenue could be hit the hardest. "(Those) properties are unique for the fact the pad elevation of the homes on these parcels are below the adjacent roadway, resulting in on-site stormwater not able to flow in to the public right of way," said City of Ripon Engineering Supervisor Elizabeth Quilici in her report to elected leaders at last month's meeting.
