This Request for Quotation (RFQ # 140P8626Q0042) outlines the scope of work for tree maintenance, removal, replacement, and irrigation installation at Aquatic Park, within the San Francisco Maritime National Historical Park. The project requires qualified contractors with specific California licensing and ISA certifications to perform services while protecting the park's historic landscape. Key tasks include pruning 12 Cordyline Australis palms to specific aesthetic standards, removing 12 diseased Arbutus trees, and grinding 13 stumps. In their place, contractors must plant 13 24-inch box Magnolia grandiflora 'Little Gem' trees equipped with root barriers and stabilizing stakes. To support the new trees, the contractor must install a fully operational subsurface irrigation system on Jefferson Street. This requires utilizing trenchless pneumatic boring methods from within the tree wells to connect 375 feet of new 1.5-inch HDPE mainline to an existing water source without disrupting adjacent paving. The contractor is entirely responsible for utility locating (including USA 811 and ground-penetrating radar), traffic and pedestrian safety control, and restoring any disturbed turf. The National Park Service will monitor quality assurance, and a final inspection with the Contracting Officer’s Representative is required upon project completion.
