Stormwater Master Planning Consulting Services for Multiple Watersheds

The City of Greenville is seeking proposals from qualified engineering firms to develop comprehensive stormwater master plans across multiple watersheds, focusing on water quality, water quantity, flooding mitigation, erosion control, and nutrient management, in compliance with federal and regional regulations such as the NPDES Phase II MS4 Permit and nutrient strategies. The scope includes updating stormwater system inventories, GIS databases, hydrologic and hydraulic models, conducting criticality assessments, public outreach, and prioritizing capital improvement projects, with deliverables comprising updated models, prioritized CIP lists, project fact sheets, and funding opportunities, all to be completed by November 2026. The procurement process is qualifications-based, emphasizing the experience, approach, and personnel credentials of the proposing team, with evaluation weights assigned to experience (30%), approach (30%), response quality (20%), and individual qualifications (20%). The City encourages MWBE participation, requiring firms to submit specific forms certifying their commitments and compliance, with sanctions for noncompliance. The solicitation, posted on September 11, 2025, mandates proposals be submitted by October 9, 2025, either electronically via a Dropbox link or as four hard copies, with a strict 15-page limit excluding resumes and attachments. The contract will be negotiated post-selection, with fees and scope to be finalized during contract development. The project’s performance and deliverables are subject to review and acceptance by the City, with no explicit physical packaging, labeling, or MIL-STD standards specified. Administrative and payment procedures involve submission of payment applications with proof of subcontractor payments, directed to the City’s designated contact, Daryl Norris. The contract emphasizes compliance with nondiscrimination laws, MWBE goals, conflict of interest disclosures, and the development of scope and fees during negotiations, ensuring a transparent, equitable process for selecting a qualified firm to support Greenville’s stormwater infrastructure improvements.
