When the existing Wanapum Dam Upper Boat Launch facility was in need of improvements, Grant County PUD relied on MacKay Sposito for design and construction support.
The improvements included the renovation of the existing boat launch facility, the addition of parking, improvements to the access road, dredging of the ramp toe to make the ramp more accessible at varying water levels, ADA parking stalls, new launch floats, interpretive signage, and the installation of a single vault toilet.
MacKay Sposito provided land surveying, developed conceptual designs, prepared cost estimates, developed the permitting documents and final design plans and specs, led the environmental permitting effort in collaboration with an environmental consultant, and assisted the PUD with the bidding process. We also assisted the PUD by providing construction management and inspection services during construction.
