As part of the Sunnyvale-Chandworth Storm Drainage Improvement project, we surveyed a 670+-acre watershed, including topographic mapping, cross section surveys, and inventory of existing utilities using aerial mapping. We met the city of Charlotte's aggressive schedule by submitting all deliverables ahead of schedule, developing a strong relationship with the client in the process. Our storm drainage system study including analysis, design, cost-benefit analysis, and cost estimates provided the city with information needed to improve the existing and inadequate storm drainage system.
