Q: On the photo enforcement cameras in Davenport, doesn’t the city need to have a sign to warn drivers about them? I got a ticket in the 5700 block of Northwest Boulevard. I’ve been back several times, and I can’t see any sign or camera there. I paid the fine, but I just wondered if they need to have a warning sign?

A: Davenport Police Lt. Jamie Brown provided the following response to Bob’s question.

The city ordinance that covers Automated Traffic Enforcement (10.16.070) does not require the city to provide a sign to alert drivers. However, since inception, the city has provided signs to help make drivers aware of the upcoming enforcement and to slow down. Signs are permanently placed with each fixed red light and speed camera in the city of Davenport.

The mobile speed van, which moves to various locations throughout the city, also does not require a sign, but the Davenport Police Department always places a temporary sign at each location. The sign is bright yellow and states: “BE ALERT SPEED ENFORCEMENT AHEAD.”

The question Bob posed stated he received a citation in the 5700 block of Northwest Boulevard. There are no fixed cameras at this location, therefore no permanent signs. The citation would have been issued from the mobile van, and the sign would have been removed from the area when the van left.

Q: My friend and I like to ride through Credit Island in Davenport and look at the Mississippi River. When you enter the park, the weeds on the west side are so tall you can’t even see the river. In fact, there are weeds all over the park. We don’t understand this. There is not hardly any grass to mow with the lack of rain. The workers should have lots of time on their hands, so why not cut the weeds down?

A: Seve Ghose, Davenport Parks and Recreation director, explained what’s going on with the landscaping at Credit Island.

In Davenport, there are naturalized areas across the city — at several parks, along the trails and on Credit Island. The naturalization provides an opportunity for the local flora and fauna to thrive. Credit Island has already shown marked improvement in attracting native flora and fauna, with the discovery last year of a flowering plant thought to be extinct in Iowa for many years.

“Credit Island is recognized as a historic park and nature preserve, and we strive to provide the community with a true nature setting in as many ways possible through the naturalized areas,” Ghose said. “These areas may take anywhere from two to three years to mature into beautiful settings, such as the areas along the Duck Creek trails, at the city golf courses and at Sunderbruch Park.”

However, in order to provide clearer viewing at Credit Island, the edges of the grassy areas are lopped off and cleaned up on a schedule. Being close to the water they do grow quickly, and parks staff will increase the frequency of the task, he said.
