Stormwater Native Vegetation Installation

The City of Sun Prairie Department of Public Works is soliciting proposals for a Stormwater Native Vegetation Installation project under RFP #24-SWU15, located at the Pumpkin Patch stormwater management facility. The procurement seeks qualified vendors to install and maintain native vegetation on approximately 3 acres of basin side slopes, with a comprehensive four-year contract that includes an initial installation phase and an alternate three-year maintenance plan. Key deliverables include site preparation, invasive species management, hydroseeding with native seed mixes, erosion control, and ongoing maintenance to achieve specific performance standards of 50% native species density by the end of 2025, increasing to 75% by the end of 2027. Evaluation criteria will assess vendor qualifications, experience, costs, sustainability efforts, and local vendor preferences, with scoring encompassing the firm's expertise, relevant project history, proposed costs, and sustainability initiatives. Proposals are due on August 30, 2024, with a contract term spanning four years and an option to extend for an additional year. Vendors must submit comprehensive documentation, including a Vendor Profile, References, Fee Proposal, and Sustainability Questionnaire, demonstrating their capability to execute the detailed Vegetation Restoration and Management Plan.

The RFP encourages participation from Disadvantaged Business Enterprises (DBE), Woman-Owned Business Enterprises (WBE), and Disabled Veteran-Owned Businesses (DVB), though these certifications will not directly impact scoring. Vendors may use subcontractors and can partner with DBE firms, although no specific credit will be awarded for such partnerships. The contract allows for potential piggybacking by other government agencies and requires vendors to provide hourly rates for additional services. Insurance requirements are extensive, mandating coverage for worker's compensation, commercial general liability, automobile liability, umbrella liability, and professional liability, with specific policy limits and conditions. While no incumbent vendor is explicitly mentioned, the project requires adherence to strict technical specifications, including using ProGanics DUAL Biotic Soil Media and native seed mixes sourced from within 350 miles of the project site. Although a specific budget range is not disclosed, the comprehensive multi-year nature of the project suggests a substantial investment in ecological restoration and stormwater management infrastructure.
