Caballos del Rio (Vista Montana III)
- Civil Engineering
The biggest challenge for the Caballos del Rio project was the unique terrain created by an adjacent wash and substantial rock and dirt removal. The site was quite sunken down compared to the surrounding area. The three main tasks to overcome were site grading, flood water and drainage management, and the sewage system.
Handling Necessary Grading with Minimal Retaining Walls
The client requested as few retaining walls to be built as possible, so the team needed to find other ways to implement the necessary grading between the sunken areas and the natural elevation grades. Dirt was resupplied where needed from the retention basins. To have a lower overall site gradient, one end of the site was lowered slightly and the other end was lifted. The lots were big enough to put in slope easements wherever needed.
Having an already low site meant that the sewer would need to be rather shallow. The team worked with City of Peoria to get a variance for the sewer plan, so that it could tie into the existing system and comply with standards.
