This site, for the Port of Poulsbo, is located on a ¾ acre site west of Jensen Avenue. The project called for the demolition of an old armory facility, to be replaced with a parking lot desperately needed to support the Port's marina operations. As the prime consultant for the client we provide all design services, including land-use & permitting.
The pre-planning phase provided various stall & access configurations to maximize use of the property. The final plan created eight elongated stalls for boat & trailer parking, as well as mixture of 48 regular, compact, and accessible stalls. The circulation layout was complicated by the maneuvering & turning radii required for vehicles with trailers. The design included an 8-ft tall concrete-block retaining wall to maximize the usable area.
Although the native soils were fine-grained, porous asphalt pavement was determined to be the most cost effective option for stormwater treatment & flow control; especially since a significant depth of gravel would be required to compensate for the low subgrade bearing value, the coarse storage-rock layer provided both pavement strength & runoff storage.
The work also included coordinating with a sub-consultant for the landscape design, and providing criteria for contractor-designed lighting. Construction support and as-built plans were also provided.
