City of Enid IDs 10 streets for overlay, overhaul

ENID, Okla. — Enid Public Works and city engineering staff have identified 10 streets they hope to finish new repairs on this fiscal year.

Among them are plans for superficial repairs and replacing sections of entire roadways.

The projects are a part of the 2014 Local Street Program, which identifies residential roads that need improvement. There are two ways the city can make repairs: asphalt overlay and concrete reconstruction. Only roads in residential areas were considered in this program.

One of the streets that will be torn up and rebuilt is Frantz, which runs alongside the pedestrian trail.

“The base of that road, the dirt underneath it and the sub-base, is pretty much gone,” City Engineer Chris Gdanski told Enid City Commission during a briefing Tuesday. “So that requires we pull the road out and rebuild it.”

Other streets needing a top-to-bottom overhaul include portions of 12th and Greg, he said.

Some delays

The Local Street Program is an annual repair calendar the city commits to finishing within the budget year. There have been some delays, though. Roadwork originally scheduled to be finished with last year’s money still is a month or two from being complete.

“The main reason for that is we had a contractor who was doing that — we asked him to pull off that particular piece of work to help us with the sidewalks, curbs and guttering downtown to meet the opening date down there,” Gdanski said. “That put him a little bit behind, but he’s catching up quick.”

The Department of Public Works maintains a running list of road conditions based on reports and studies, which includes film and sonar measurements. The department prioritizes that list each year and then sends it to the engineering department, which performs an initial estimate of the repairs.

The two offices then coordinate to produce a final list.

City Manager Eric Benson said the city also takes suggestions from the public and commission.

“We accept input all the time. We allay that against the structural findings,” he said. “At any time, anyone can make a suggestion.”

The requirements, he said, always exceed the amount of money the city commission budgeted for road repair.

When the base of a roadway still  is structurally sound to support traffic, engineers may only recommend adding an overlay. Essentially, the city will add a layer of asphalt to the road. In most cases, this process increases the height of the road, so they must consider how curbs and gutters would be affected.

The three areas in the 2014 Local Street Program receiving an overlay are a section of Van Buren that departs the northern bypass, Oxford just east of Van Buren, North Washington and the West Evandale subdivision at the corner of Garland and Rupe.

The difference between the two ways of repairing roads is a matter of money and time. A concrete reconstruction will last decades; a layer of asphalt will need attention more quickly.

The city also must decide whether to move utility lines if they are under the road. Benson has said as the city built roads, it also would lay water lines directly underneath them. When those old lines fail, though, it requires digging down into the street to fix them.

Now, when a road is rebuilt, the city will move the utilities to an adjacent right of way.

“It’s plain in our benefit not to put a brand new road down over a decaying underground line, because we have to tear it all up; then we can’t ever make it right again,” Benson said. “A mile of road is very expensive, because we basically have to do two projects.”

Public Works Director Jim McClain also told the commission about a product he intends to start using to repair low-traffic streets.

Repairs with Modified Aggregate Quick Set, or MAQS, are performed by Missouri-based Donelson Construction Co.

About 27 percent of Enid’s roads would be ideal for the mixture.

“With a really good maintenance program and maintenance material, they (roads) could be saved. And the life of those could be increased eight to 12 years at a very reasonable cost,” he said.

Nearly a mile’s worth of overlay at Quailwood and Rolling Oaks cost the city just $48,800, McClain told the commission Tuesday. MAQS currently is in use throughout Tulsa County.

“We plan on using a lot of that and step up our maintenance program a little bit so we’ve got some streets that we can extend the life of, and not be sitting back here 50 or 100 years from now trying to get street work done,” said McClain.
