Street Maintenance & Road Repair
| Above: A Highland Village road that was repaired using crack sealing. |
The useful life-span of both concrete and asphalt streets can be extended through a variety of street repair and preventative methods. The City's budget for street renovation is sufficient to pay for ongoing maintenance needs, but unfortunately, not sufficient to meet the restoration needs for streets that have failed.
Given this limited budget, the City has developed a priority plan to identify a limited number of streets for reconstruction. Streets targeted for reconstruction are brought forward every four to five years as a bond issue. For the remaining majority of streets not yet candidates for complete street reconstruction, the City utilizes less financially prohibitive methods of street repair and maintenance including:
- preventative crack sealing: Although aesthetically unappealing in the eyes of some, preventative crack sealing is a cost-effective way fill pavement cracks caused by ultra-violet rays and bad weather with a hot, rubberized asphalt so that water does not enter the base and cause extensive damage.
- asphaltic mill and overlay: A method whereby an inch and a half layer of new asphalt is laid over existing pavement and rolled to a smooth finish for a new driving surface that typically lasts 7-12 years, depending on road usage.
Traffic Sign Replacement Project
An ongoing City project is the installation of higher reflectivity traffic signs and pavement markings to meet the Federal Highway Administration's new minimum brightness or "retroflectivity" standards by the January 2018 deadline. According to the U.S. Department of Transportation, the new standards will improve road safety by making streets easier to navigate at night-time and in other low-light conditions. The new standards, however, do not apply to such markings as crosswalks, chevrons, parking space markings and lane-use arrows.
Highland Village's method for measuring the reflectivity of traffic signs and bringing them up to the new minimum requirements will be established and implemented by January 2012. By January 2015, Highland Village expects to have identified all regulatory, warning, and ground-mounted guide signs (except street-names) needing replacement. All street names and overhead guide signs not in compliance with the minimum reflectivity standards will be replaced by January, 2018.
