Q. Why are the street lights not working on the west side of Brown Street between 4th and 5th streets in Davenport? They have been out for a while. -- Kyle

A. We contacted the city of Davenport to find out. Nicole Gleason, Davenport public works director/assistant city administrator, responded:

"There is currently a coordinated effort between the Downtown Davenport Partnership and Public Works to take over the maintenance for all privately operated street lights. The ones referenced in this email are actually powered by the business on this block and the city does not have access to power. The first such contract was executed on the last council cycle, and we will continue until we have agreements with all private lights that are lighting public streets. The long term goal is to get these lights on the City of Davenport power grid, however, this will take time as we plan to convert them as construction/repairs are occurring."

Q. What are all of the orange markings on trees along Interstate 80 between U.S. 61 and the Mississippi River? -- Reader

A. We contacted the Iowa Department of Transportation to find out. Catherine Cutler, transportation planner, District 6, Iowa DOT, responded:

"We have a project coming to clear up some dead/sick trees and invasive species of trees. Orange markings indicate removal. Blue markings on a tree means it stays."

We also asked if this was an Emerald Ash Borer infestation? Cutler said, "Yes, some. Tree of heaven and red cedar are others. Cedars are a special nuisance as seeds are spread by birds and get into farm fields."

Q. Do any local police departments enforce window tint laws? I am seeing more and more vehicles with extremely dark windows. -- J.W., Walcott, Iowa

A. We contacted the Walcott, Iowa, Police Department; the Davenport Police Department, the Bettendorf Police Department and the Scott County Sheriff for more information.

Walcott Police Chief Jeff Blake said, "We just just recently ordered window tint meters to enforce that law. After receiving them and training the officers we will use the meters."

Bettendorf Police Chief Phil Redington said, "The Bettendorf Police Department does enforce our tinted window laws. Since January 1, 2017, our officers have issued 37 citations and 90 written warnings for dark windows/tint violations.

The Davenport Police Department has not responded. However, a similar question was posed in Ask the Times in 2015. Here was their response at that time:

A. We contacted the Davenport Police Department to find out. Capt. Brent Biggs responded:

"Traffic units are equipped with tint meters, and additional equipment is available for check out on the patrol shifts. The past year 186 (citations and warnings) have been issued for obstructed vision violations, which covers tinted windows."

The Scott County Sheriff's Department has not responded. We will include any responses we receive from the Davenport Police Department or the Scott County Sheriff's Department in a follow up. For more information on window tinting laws visit qctimes.com/askthetimes.
