BACKGROUND
County Staff and Consultants have recently completed a comprehensive review of conditions along Mt. Veeder Road and numerous problem areas were identified where “preventative” maintenance can be considered to reduce risks of emergency repairs. The site that was judged to have the highest risk of damage that would be both costly to repair but also result in a likely complete closure of the roadway is at Mile Post 3.42 (just south of 2080 Mt. Veeder Road). Although it didn’t collapse then, the storms of November 2025 significantly weakened this area. The two “failures” that are possible at the site are significant roadway settlements due to a likely void where water has washed soils away below the culvert or an outward rotation/collapse of the wall which will result in a rapid drop of the roadway surface, likely closing the entire road. At this location, a 30-inch diameter culvert crosses under the roadway and an old concrete block wall is located on the downhill side of the road and around a culvert. The old wall extends down about 12 feet and below that, erosion from the culvert has resulted in another vertical slope so the total drop from roadway to ground surface below the culvert is about 16 feet. The old concrete block wall exhibits significant cracking and has...
