Indigo provided planning, civil engineering design and local and state permitting services to convert a former 5-story 100+ year old textile mill building into a new 68-unit workforce housing apartment complex and commercial offices. Indigo provided complete civil engineering services including site layout, access road and parking lot design, sight line evaluation, drainage design and planning, zoning, wetlands and DEEP and DOT approvals. A unique aspect of this project was that a portion of the Hockanum River flows under the western end of the building. This project incorporates an overflow culvert to prevent flooding of the lowest floor of the building. Due to this, Flood Management Certification was required through the DEEP. Indigo is also providing coordination during construction.
