The San Luis Creek Walk is part of the Mission Plaza expansion in downtown San Luis Obispo. The Creek Walk is located along a portion of San Luis Obispo Creek near the corner of Higuera and Nipomo Streets, and near the San Luis Obispo Children’s Museum. The improvements include a pedestrian bridge that spans the creek, and walkways and stairways supported by small retaining walls. Earth Systems performed a soils engineering investigation which entailed site reconnaissance, field exploration, laboratory testing of soil samples, geotechnical analysis of data, and provided geotechnical recommendations for site preparation and grading, foundations, retaining walls, flatwork, and site drainage. During construction, Earth Systems provided observation of caisson drilling and construction, and special inspection of concrete placement.
