The Stumblr is a blog devoted to documenting some of the worst sidewalks in San Diego, California.  Some of these sidewalks would make for good X-Games ramps.

MicroPAVER Field Inspector 1.0

PAVER Field Inspector™ is the new PAVER™ companion software that takes advantage of GIS/ GPS state of the art technology as well as innovative graphics to facilitate pavement inspection using handheld computer tablets.

The program allows the user to identify his location on a pavement network map displayed on his/her tablet computer.  As the user clicks on the section to be inspected, the program already knows all the section information and the user is ready for immediate data entry.  As the user is entering pavement distress data, the PCI is being calculated and displayed to the inspector in real time and the program has built significant data entry validation tools to identify errors before they are recorded.

When inspecting concrete pavement, the program allows the user to generate graphics of the individual concrete panels (slabs) and record identified distresses on each slab.  These graphics are stored with the inspection and can be viewed later.  When inspection is completed, the program generates an error free XML file for import into PAVER.

The program has wide applications especially for agencies with more than one  evaluation team where each team is assigned to inspect different parts of the airfield and the data are later imported into the main copy of PAVER™.

SR-125 Road and Storm Drain Condition Evaluation

Opened in 2007, the State Route (SR) 125 toll road is approximately 10 miles long and extends from HWY 54 to I-905 in the City of Chula Vista, San Diego County, California. The city of Chula Vista witnessed rapid growth in housing development during the housing boom of the mid-2000s. An estimated 30,000 residential, commercial, and other parcel units were slated for development in this region. The SR-125 toll road, which was privately operated by South Bay Expressway (SBX), was created to accommodate this rapid expansion.

However, the economic slowdown of 2008 arrived and hit boom towns like Chula Vista particularly hard. Ridership and revenue projections made during the boom cycle fell short under the reality of recession. On July 29, 2011, the San Diego Association of Governments (SANDAG) voted to purchase the lease from SBX for about $345 million with various contingencies.

VanderHawk Consulting LLC was contracted to perform a condition assessment of the road pavement and storm drainage systems on the SR-125 toll road and report the findings. The road pavement condition assessment was performed in accordance with the MicroPAVER pavement management protocol, while the storm drainage assessment was performed in a manner consistent with CalTrans’ storm drainage system evaluation procedures.  Almost 1,400 images (many geo-tagged) were captured for this project and comprise the most extensive analytical photo archive of the SR-125 toll road and drainage networks to date.
