DGR performed the boundary and topographic surveying as well as the site design of school building addition as a subconsultant of Architecture, Inc.
The school facility addition design included storm sewer upgrades, pedestrian facilities to multiple building levels, enhanced and expanded parking, as well as significant embankment work to match the existing site constraints.
The addition cut off an existing overflow drainage path so an enhanced storm sewer system capable of draining runoff from a 500 year storm event was designed and constructed.
This project required working with a building design team and ownership group to overcome design challenges and communicate with all project stakeholders. The facility was completed and opened in late fall of 2015 for the Central Lyon Community School District.
