Olalla boat ramp gets pervious pavement

The in basket: I happened past the inlet and boat launching area at Olalla a couple of weeks ago and saw what appeared to be dead trees lying laterally along the toe of the parking area, best known as the site of the annual Jan. 1 Polar Bear plunge.

I was in too big a hurry that day to stop, so went back Wednesday to check out what I’d seen. By then a couple of tree root balls protruded from the soil along the edge of the newly paved boat launching ramp. They were enclosed in a planting area of native-looking vegetation that separated the new pavement from the water.

I asked County Commissioner Charlotte Garrido at last week’s ribbon cutting at the new Blackjack Creek pedestrian bridge in Port Orchard what was happening in Olalla and she referred me to the county parks department.

The out basket; Parks director Jim Dunwiddie says the boat launch is the fourth county park property to get pervious pavement that lets storm water pass through rather than running untreated into the salt water. The native plantings constitute a water garden that will filter pollutants out of what runoff gets that far.

“There was some paving breaking off into the water and we had no real way to address the water runoff in that area (before the work),” he said.

The Point No Point, Wildcat Lake and Horseshoe Lake parking areas were done last year, he said.

The boat ramp has been closed since Oct. 5, but may be open again by now. The paving was done Wednesday and cones and tape barricaded it that day. Some future short closures are possible for paint striping.

The project is described on the park’s Web site, www.kitsapgov.com/parks/. It says the next closest boat launches for small craft are  in Manchester and Gig Harbor.

Jim said he doesn’t expect the changes to interfere with the Jan. 1 Plunge

Striping in a tight S-curve is no picnic

The in basket: Bob Cairns of Olalla says, “Recently lower Banner Road in Olalla was restriped with the exception of the very dangerous s-curves whose lines are obscured, doubtless, in large measure, from being ridden or crossed over by traffic.

“Was this an oversight? Does the county plan to return and restripe this area?”

The out basket: It’s a logistical thing, says Jeff Shea, Kitsap County’s traffic engineer.

“Sharp corners like this are very challenging for a striping crew,” he said. “As good as they are, this situation is nearly impossible to restripe after the original stripe is painted.”

He attached a photo of what can result from trying.  “Each subsequent line is slightly off the original which makes the line look like a solid very wide line,” he said.

“Safety is also a factor on sharp limited visibility corners such as this. The striper maintains a constant speed when striping to get the required thickness of paint. At the same time it is essential that the driver be watching the centerline for a straight true line. Add the difficulty of a large truck with a long wheel base which makes cornering even more difficult.

“So it is pretty easy to see how difficult it would be for the driver to maintain speed while trying to maneuver a sharp limited visibility corner, not to mention narrow road with oncoming traffic.

“We are looking at alternative methods for the centerline, either thermoplastic line or raised pavement markings.  Either solution should make the corner very visible and easier to maneuver while staying in the correct lane of traffic,” he said.

Pavement losing its color at Burley-Olalla

The in basket: As I drove north on Highway 16 past the new Burley-Olalla Road interchange recently, i thought the wheel paths in the pavement had lost more of their black coloration than I would have expected. The asphalt looked more like what I see on aging parts of I-5, but without the obvious rutting and the loud tire noise. 

I asked if the asphalt wasn’t wearing well.

The out basket: The project engineer for the interchange project, Brenden Clarke, says the loss of color is normal.

“It is typical for asphalt pavement to fade to gray in about nine months,” he said. “The pavement is actually wearing well.”
