KS Associates was retained by the City of North Ridgeville to prepare plans and specifications, assist in bidding and oversee the construction of a major sanitary sewer extension. The project consisted of 11,500 linear feet of sanitary sewer at depths reaching 25 feet.

In the design phase, KS Associates prepared a sanitary sewer master plan for the south Lear Nagle area taking into account estimated future flows from industrial, commercial and residential areas. Based on the master plan, KS Associates performed all topographic surveys along the Lear Nagle Road/Lorain Road/Cook Road corridor. A soil consultant was retained to investigate subsurface conditions at key locations. Soil conditions, which included water-bound sand and sandstone, proved to be major challenges in both design and construction.

KS Associates worked closely with the city auditor and bond counsel to determine the financing for the project; attended the bid opening; provided full-time resident project representation to observe the activities of up to five construction crews working simultaneously; and helped address the residents’ concerns about the quality and appearance of the final landscaping.
