Budget estimate

$500,000 – $2,000,000

Based on typical county IDIQ contracts for stormwater technical services, a medium‑size consulting firm could expect annual awards ranging from roughly $500,000 to $2,000,000, depending on scope breadth, staffing levels, and the number of task orders issued. The lower bound reflects a limited‑scope, low‑volume engagement; the upper bound assumes multiple, complex task orders covering extensive monitoring, reporting, and advisory functions.
