Rose Street can smell sweet

I offer considerations for Rose Street reconstruction. Design starts by viewing projects holistically. Replacing cold storage facilities with a hotel complex will generate new interest, enterprise and construction along Rose Street making it a major thoroughfare.

Retain healthy trees that don’t restrict cohesive traffic configuration. Rose must be four lanes with sidewalks on both sides.

Sporadic trees, a winding sidewalk with frequent elevation variation, railroad tracks, etc. is not attractive for a north side bike path.

The south sidewalk can be near straight, carrying a larger volume of pedestrians to commercial, hotel, eateries, big box stores, etc. Widen the sidewalk six feet and use an expansion joint delineating the two uses. Justify exceptions per WSDOT guidance for bike lane design; i.e. low bike traffic, etc.

Who pays for bike pavements operation and maintenance?

On both sides of Rose Street utilize bus turnouts accommodating two buses each plus a shelter at strategic locations but not close to intersections where they could obstruct a driver’s view of pedestrian movements.

Utilities should take advantage of construction mayhem to place facilities underground. No poles in sidewalks.

In this era of wanton property destruction and criminal activity be certain streetlights flood the corridor and cameras survey all the areas.

A most important design element is the roadway pavement choice — rigid or flexible concrete. Both use aggregates of sand, gravel and/or crushed rock configured to prevent overstressing the subgrade while supporting heavy traffic. Their main difference is the cement that binds the particles together; Portland cement for rigid or asphalt cement for flexible concrete.

Portland cement concrete lasts for decades without patching. Flexible pavements need continual traffic to massage the surface and prolong its use before needing maintenance; sealing, patching and eventual overlay.

Roller-compacted concrete has undergone massive change. It is the most competitive pavement today.

Roller-compacted concrete must be included in bidding documents as an alternative. It will become a standard for new and rebuilt streets.

We may want to buy our own paver and lease it to others.

By the way, College Place needs solid configuration ASAP to aid its planning and implementation. It move quite rapidly.

Mr. Kelly,

Really? If you would ask some questions, you would find out that the reason for the need to revamp Rose is because it is because of concrete roads. The valley had alot of concrete roads. Concrete roads are very expensive, more than our city can afford, or at least more than is prudent, concidering it would take funds away from other areas. Also, all of Rose St. (WW and CP portions) and College Avenue have a concrete base under the blacktop asphalt. The two materials do not constrict and expand the same way. So, when you look at most of the "chuckholes" there is only an 1 to 1.5 inches to a concrete layer. They say that asphalt does not stick in thin layers to concrete very good. So both cities are planning on having to remove the concrete base and replace it with new bedding and then asphalt. Last year, the CP voters passed a bond, to replace and repair all of Rose and College Ave. That project includes some new intersections and some new sidewalks/bike paths. I asked about a time schedule for their construction, they plan on this summer if funding is ready, or next spring at the latest. Please educate yourself before making plans for our taxes!
