Site work for a mixed-use development in Grass Valley, California. Completed plans call for site work for a playground / park / athletic field.

**As of December 19, 2025 , this project has not yet been awarded. The project is expected to be awarded on December 23, 2025.** This Request for Proposals is for Design-Build contract to develop an approximately 23,00 square foot new permanent all wheel bike park located at 111 Centreville Rd Grass Valley Ca. The City has established a budget of $1,100,000 for this turnkey project which will include all design, surveying/mapping, engineering, public outreach, construction and all other actions required to erect a new bike park, complete and in place, ready for public use. B. PROJECT OVERVIEW This section provides a project overview for the Project to assist proposers with the minimum items the City will require be included in this Project: _ The intent of this project is to create a high-quality, all-wheel pump track and bike park that blends recreational function with environmental sensitivity and aesthetic harmony. The facility shall provide a safe, engaging, and visually appealing riding experience for users of all ages and skill levels while integrating seamlessly into the surrounding park setting. The design should emphasize flow, sustainability, and long-term durability, using natural materials, thoughtful grading, and native landscaping to minimize maintenance and complement the park's character. _ The Design-Build Contractor shall design and construct the interior of the pump track and surrounding site to achieve a clean, cohesive, and natural aesthetic that integrates with the surrounding park environment. The completed facility shall reflect high-quality craftsmanship, visual appeal, and durability suitable for year-round public use. _ The riding surface shall consist of a smooth, continuous asphalt track featuring a balanced layout of rollers, berms, and banked turns that support both beginner and advanced riders. _ The layout shall promote flow, rhythm, and safe circulation, with multiple line options where feasible. _ Track edges shall transition cleanly into adjacent surface materials to minimize maintenance and improve rider safety. _ Construction of a 6-foot asphalt pathway around the perimeter of bike park connecting back to existing asphalt path at each end shall be included in the design. _ Landscaping shall utilize native or drought-tolerant plant species to enhance aesthetics, support erosion control, and reduce maintenance requirements. _ Plantings shall be used to define circulation areas, provide spectator buffers, and visually soften the perimeter of the riding area. _ All landscaping shall comply with the City's approved plant palette and irrigation standards. _ Grading and drainage improvements shall ensure positive runoff away from the riding surface, preventing puddling and sediment accumulation. _ Perimeter areas and any disturbed soils shall be stabilized with hydroseed, vegetative cover, decomposed granite, or other erosion-resistant materials consistent with the overall design aesthetic _ Exposed slopes shall be treated to prevent erosion and ensure a stable, finished condition. _ Benches, bike racks, shade structures, trash receptacles, and signage shall be included in the design to support rider and spectator comfort. _ Furnishings shall be of durable, vandal-resistant materials that complement the park's existing aesthetic and color palette. _ Signage shall include facility rules, safety information, and acknowledgment of project sponsors or partners as directed by the City. _ The Contractor shall leave the site in a clean, fully stabilized, and visually appealing condition upon completion. _ All disturbed areas outside the project limits shall be restored to pre-construction or better condition. _ Final grading and landscaping shall blend seamlessly with the surrounding park terrain. _ Preliminary engineering design. _ Community outreach - please provide your suggested methods for community outreach (project website for public comments, public meetings, etc.) _ Surveying, engineering, and design services for the construction of a bike park for the Project, including environmental documentation, engineering cost estimates, final design, plans and specifications, complete contract documents for bidding and other work as necessary to provide a complete Project. _ If required based on proposal, provide potential phasing of the project based on available funding. _ Construction bidding oversight. _ Engineering services during construction for geo-technical testing and to provide solutions if field conditions require a deviation from the approved plans and specs. _ Special inspections during inspection, as required Question Deadline 11/21/2025 at 10:00 AM PT Questions may only be submitted to the Citys Project Manager Zac Quentmeyer, at: zacq@cityofgrassvalley.com The City reserves the right to terminate the RFQ/RFP process at any time.
