In my opinion the key to a long-life concrete or brick unit paver surface–assuming the foundation structure is properly built–is re-sanding. As discussed in other articles at this blog the sand is the “glue” that “locks” the individual pavers together.

State law in Texas requires someone digging in the public rights of way to call “One Call” who then notifies all utilities the area where digging may occur so the utility can mark the locations of their underground facilities. That is a good as it preserves the services expected by the utility’s customers and the utility does not have to make repairs thereby increasing the cost to the customers. It also protects the workers doing the excavation as, for example, hitting a high-voltage duct bank is not a healthy thing.

But the issue is in the application of the markings. There are published guidelines for the style and frequency of the markings as well as the color. The color indicates the business type of the utility, e.g. telecommunications, power transmission, natural  gas. The frequency of the marks can remove all doubt about the location as well as remove all value of the classy, upscale look paid for by the public.

I have had the great opportunity and pleasure of managing three archeological investigations related to projects in the oldest part of Houston Texas that is also in the core of downtown. This post is to share my experiences and what I learned to hopefully assist someone who may be where I was when I began the RFP process for the first project.  I acknowledge I had the benefit of Bob Eury’s (Central Houston and the Downtown District) experience and great advice from Dr. Roger Moore that helped me avoid  learning some things the hard way.

The state law in Texas requires a message 15 feet from each radius point of an intersection to restrict drivers from parking so close to the turn that other drivers cannot see on-coming traffic. If that message is on a typical sign then the intersection has  four more pieces of clutter in the form of a galvanized  or zinc-coated post adorned with a blue sign with its bolts and nuts. If the installation  is like most then we would also have a base plate bolted to the sidewalk with four bolts that soon start rusting. In general this will not create a positive streetscape amenity.

One of our Cotswold projects anticipated removing many old street bricks. We found bricks in many streets but the street where they were to be saved for reuse was also where we were removing unused old railroad tracks and placing the new water, waste water and storm water lines. But, we did not find enough bricks to rebuild the planned two blocks of Commerce Street either side of Main Street.

Looking back on that disappointment I now believe that was a blessing. Not that it was a bad idea but that we did not have the contract requirements in place to recreate a pavement equal to what our forefathers built. We also did not have a consistent brick source. We did plan plan to install the old bricks on a concrete slab to support the heavier vehicles of today.

This post is for the purpose of celebrating the generations of people who have worked for many years in our urban places long before the term urban was used and blogs were read. Our reconstruction/revitalization of the historic end of downtown Houston dug through some of the oldest soil in the city. When we rebuilt Commerce St. at Fannin St. we were only a few feet from Allen’s Landing where Houston began.
